Answer:
26 + 8x.x = 15.Step-by-step explanation:
Marise has 26 pokemon cards. Marisa claims that he will have 146 or more cards after she receives her shipment of 8 packs of cards.
So, we have to make a unknown value on 8.
8x.Now, we have to find out that unknown value:
26 + 8x= 26 + 8(15)= 26 + 120= 146.x = 15.There will be 15 cards in Marisa's 8 boxes.

∠2 and ∠5 are adjacent as they lie right next to ∠1C. Angles 2 & 514.
∠5 will form a linear pair as they add up to 180°C. Angle 515.
∠2 = 180° - 70° - 50°∠2 = 60°B. 60°16.
A. ∠RVT and ∠RVUAnswer:
13. C. Angles 2 and 5, becuase adjacent means the angles are touching and right next to each other, and three is too far away and is not buffering up to angle 1.
14. That would be C. angle 5, because linear pair angles are angles that share a line and would add up to 180, in this case only angle 5 does that.
15. B. 60 degrees, to find out angle 2, you first need to know the information that a line=180 degrees, and all three angles share a single line being line TQ. so all you have to do, is add up the angles you know, so 70+50=120, and then subtract them by 180, giving you the remainder that is unkown, in this case being angle 2, so 180-120=60.
16. A. angles RVT and angle RVU, remember, ajacent angles are angles that share a side and buffer each other, in which angles RVT and RVU are the only ones that do that.
From the top of a lighthouse 160 feet above sea level, the angle of depression to a boat
at
sea is 25 degrees. To the nearest foot, what is the horizontal distance from the boat to
the base of the lighthouse?
Answer:
75 feet
Step-by-step explanation:
The perpendicular height from the base of the lighthouse to the top is 160 feet. The angle of depression is the angle that is adjacent to this side. The opposite of this angle is the horizontal distance from the boat to the base of the lighthouse, so we need to use the tangent. tan 25°=x/160, tan 25° is 0.466 so when we multiplty by 160 to find x, we get x=74.56, which rounded up is 75.

Can anyone solve this correctly?
Answer:
J. x = 1
Step-by-step explanation:
Write an equation based on the image of the scales.
3x + 6 = 9
Subtract 6.
3x = 3
Divide by 3.
x = 1
If you haven't learned to solve equations yet, the same thought process can be used with the scale image. The scales are balanced. To keep them balanced, remove 6 of the pieces marked "1" from BOTH sides of the scale. Then the scale will have three x's on one side and three "1"'s on the other side. So each x has to be one "1".
Which values of c will cause the quadratic equation -x^2+3x+c=0 to have no real number solutions? Check all that apply.
Taking into account the discriminant of a cuadratic function, values of c less than[tex]-\frac{9}{4}[/tex] cause the quadratic equation -x²+3x+c=0 to have no real number solutions.
Discriminant of a cuadratic functionThe function f(x) = ax² + bx + c with a, b, c real numbers and a ≠ 0, is a function quadratic expressed in its polynomial form (It is so called because the function is expressed by a polynomial).
The following expression is called discriminant:
Δ= b²- 4×a×c
The discriminant determines the amount of roots of the function. The roots are those values of x for which the expression is 0, so it graphically cuts the x-axis.
Then:
If Δ <0 the function has no real roots and its graph does not intersect the x-axis.If Δ> 0 the function has two real roots and its graph intersects the x-axis at two points .If Δ = 0 the function has a real root and its graph intersects the x-axis at a single point that coincides with its vertex. In this case the function is said to have a double root.Value of cIn this case, for the quadratic equation -x²+3x+c=0 you know:
a= -1b= 3c= cIf the function has no real roots, the discriminant is less than zero (Δ <0). This is: b²- 4×a×c < 0
Substituting the corresponding values, you get:
3²- 4×(-1)×c < 0
Solving:
9 + 4×c < 0
4×c < -9
c< (-9)÷4
c< [tex]-\frac{9}{4}[/tex]
Finally, values of c less than[tex]-\frac{9}{4}[/tex] cause the quadratic equation -x²+3x+c=0 to have no real number solutions.

write an approximate equation of the line of best fit, then predict the average temperature.
Answer:
[tex]\textsf{\sf(a)} \quad y=-\dfrac54x+\dfrac{205}{2}[/tex]
(b) $46.25
Step-by-step explanation:
When adding a line of best fit, ensure that the number of points above and below the line is about equal.
See attachment for line of best fit.
Part (a)From inspection of the graph, two points on the line are (10, 90) and (50, 40). Therefore,
[tex]\textsf{let}\:(x_1,y_1)=(10,90)[/tex]
[tex]\textsf{let}\:(x_2,y_2)=(50,40)[/tex]
Calculating the slope of the line:
[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{40-90}{50-10}=-\dfrac54[/tex]
Using the point-slope form of linear equation: [tex]y-y_1=m(x-x_1)[/tex]
(where m is the slope and (x₁, y₁) is a point on the line)
[tex]\implies y-90=-\dfrac54(x-10)[/tex]
[tex]\implies y-90=-\dfrac54x+\dfrac{25}{2}[/tex]
[tex]\implies y=-\dfrac54x+\dfrac{205}{2}[/tex]
(where x is the average monthly temperature in °F and y is the monthly heating costs in dollars)
Part (b)Substitute x = 45 into the equation found in part (a):
[tex]\implies -\dfrac54(45)+\dfrac{205}{2}=46.25[/tex]
Therefore, the monthly heating cost for a month with an average temperature of 45 °F is approximately $46.25

What type of angle is shown below?
29°
O A. Obtuse
O B. Acute
O C. Right
O D. Straight
Help pls
Answer:
B. Acute
Step-by-step explanation:
Any angle less than 90 degrees is an acute angle. A 90-degree angle is a right angle, and is typically marked with a little box. Any angle more than 90 degrees and less than 180 degrees is an obtuse angle. A 180-degree angle is a straight angle and is basically just a line.
Since 29 degrees is less than 90 degrees, we know that the answer is B, an acute angle.

Addition of two polynomials:
Like terms have same variable with same power. Combine like terms.
(-16x² & -5x² are like terms ; 10x and (-2x) are like terms ; (1 and 1 are constants)
-16x² + 10x + 1 + (-5x² - 2x + 1) = -16x² + 10x + 1 -5x² - 2x + 1

Neil and his mom are volunteering at an emergency relief center. To help prepare in case of a flood, they pack emergency kits with food and water. Neil puts 3 water bottles into each kit they pack. In all, he packs 150 water bottles. Which equation can you use to find the number of emergency kits k Neil packs?
The number of emergency kits that Neil packed in total for the 150 bottles is gotten as; k = 50 kits.
How to create equations?We are told that Neil puts 3 water bottles into each emergency kit packed.
Now, let the number of emergency kits be k.
Thus;
3k = 150
Division property of equality, we have;
3k/3 = 150/3
k = 50
Thus, the number of emergency kits that Neil packed is gotten as k = 50 kits.

Which equation represents a line which is parallel to the line x-
8y = 48?
Answer:
y = 1/8x
Step-by-step explanation:
REMEBER: When the slopes are two lines are equal, they're parallel.Given Equation:
x - 8y = 48 ---> This equation is in standard form.⇒ -8y = -1x + 48
⇒ y = 1/8x + 6
As a result, the equation of the parallal line to the given equation x - 8y = 48 is:
⇒ y = 1/8x
Which is true for
the vertex?
A. A vertex is any angle.
B. A vertex is the end point of a single line segment.
C. A vertex is a point that describes the corner or
intersection of an angle.
Answer:
C.
Step-by-step explanation:
It is the corner or a point where line segments meet.
Hi!
Your answer is C.
The vertex is the point where two different rays meet, forming an angle.
It can also simply be the point where 2 straight lines simply meet.
Option A is NOT correct because a vertex is not angle, it is a part of an angle.
Option B is NOT correct because, if there's only one segment, we cannot form a vertex.

Which algebraic expressions are binomials? Check all that apply
Answer:
Of the ones listed, in the way they are written, the answers are x²y – 3x and 6y² – y.
Explanation:
A monomial is a constant, a variable, or the product of constants and variables. A binomial is the sum or difference of two monomials.
The first option, xy, is a monomial. There is only one, so it is not a binomial.
The second one, x²y-3x, is the difference of two monomials; this means it is a binomial.
The third one, 6y²-y, is the difference of two monomials; this means it is a binomial.
The last one, y²+4xy-x², is the sum and/or difference of at least three monomials (there is a plus at the end that makes me think there is more to it). This means it is a trinomial, not a binomial.
Answer: B, C, and E.

Since all three show the characteristics found in a binomial then these three are your answers. Plus I just did it on Edge.
