Answer:
d = -1/4 or -0.25
now that i helped you can you go follow my twitch KayduxTV
Step-by-step explanation:
Answer:
d= -1/4
Step-by-step explanation:
First: subtract 2d from each side so you end up with 4d-11/2=-13/2
Second: next add 11/2 to both sides so you end up with 4d=-1
last: divide each by 4 to get d by itself
your final amswer is d=-1/4
The length of the window is 2m longer than its width and the area is 32m^
Answer:
X¹= -2 + 2√33
X²= -2 - 2√33
Step-by-step explanation:
X × (X+2) = 32
X² + 2X = 32
X² + 2X - 32= 0
Δ=132
X= -2 ± 2√33
X¹= -2 + 2√33
X²= -2 - 2√33
(You can change the 2√33 to 11,5 if you want to)

If _A = 28°, what must the measure of D be in order for A ABC to be similar
to A DEF?
A. 14
B. 28
C. 31
D. 62°
Answer:
62°
Step-by-step explanation:
If it is a right triangle, subtract 90, from 180 and then subtract 28 to get D. D should = 62°
D must be equal to 28° in order for triangle ABC to be similar to triangle DEF.
The correct answer is option B.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
We know that if two angles of a triangle are congruent to two angles of another triangle, then the triangles are similar.
Since angle A is congruent to angle D, we need to find the value of D that makes this true.
Therefore,
D must be equal to 28° in order for triangle ABC to be similar to triangle DEF.

Over what interval is the graph of y=−2 +|x− 2| increasing?
a. (2, ∞)
b. (−2, ∞)
c. (−∞, −2)
d. (−∞, 2)
Answer:
(2, ∞)
Step-by-step explanation:
An absolute value graph at (0, 0) is an up facing V shape graph. After a few transformation, according to the equation y = −2 + |x− 2|, we have our vertex at (0, - 2). It remains at up facing V graph.
x - h,
x - 2,
x - (+ 2),
h = 2
Therefore our slope is 2, with out vertex at (0, - 2). If we plot our graph, you can see that on the interval (2, ∞) the graph increases...

Multiply using the foil method than combined the real and imaginary parts of the expression
bc = ad
solve for a
Answer:
[tex]\huge\boxed{a=\frac{bc}{d}}[/tex]
Step-by-step explanation:
In order to find the value of a when we have the equation [tex]bc=ad[/tex], our goal is to isolate a on one side.
The key question here is: what's stopping a from being alone on one side? That would be it being multiplied by [tex]d[/tex]. If we were able to remove the d, we would have a by itself.
Since we are multiplying a and d, we can get rid of the d by dividing both sides by d.
We have to divide both sides of the equation by the same value in order to keep it equal.
[tex]bc \div d = ad \div d\\\\\frac{bc}{d}=a\\\\a = \frac{bc}{d}[/tex]

Bob is trying to see if his shadow is longer than Kevin’s. Kevin is 3 feet tall, and Bob is 2½ feet tall. Kevin’s shadow is 5 feet long. Help Bob find the length of his shadow
Given parameters:
Height of Kevin = 3ft
Height of Bob = 2.5ft
Hieght of Kevin's shadow = 5ft
Unknown:
Length of Bob's shadow = ?
We can simply set up simple ratio to solve this problem.
The ratio of Kevin's height to Bob's height is 3 : 2.5
The ratio of their shadow should also be 5: Bob's shadow height
Equating the two of them should give a fairly constant ratio;
[tex]\frac{3}{2.5} = \frac{5}{Bob}[/tex]
3Bob = 5 x 2.5
Bob's shadow height = [tex]\frac{5 x 2.5}{3}[/tex] = 4.2ft
The height of Bob's shadow is 4.2ft.

Answer:
Number line from negative 10 to positive 10 in increments of 1 is shown. Only the whole numbers are labeled. A point labeled R is placed between the 4th and 5th tick marks to the left of 0. A point labeled T is placed on the 3rd tick mark to the right of 0.
Step-by-step explanation:
The points given are (-4.5,0) and (3,0), which means the points are on the x-axis. Point R (-4.5,0) will be located to the left of 0, the negative side of the number line between the 4th and 5th marks. Point T (3,0) will be located to the right of 0, the positive side of the number line at the 3rd mark.
The second answer is incorrect because point (-4.5,0) is not on the right side of 0 but on the left side.
The third answer is incorrect because point T(3,0) is place between 2 and first mark instead of the third mark.
The fourth answer is incorrect because R (-4.5,0) is placed on the first mark instead of between 4th and 5th mark.

Number line from negative 10 to positive 10 in increments of 1 is shown. Only the whole numbers are labeled. A point labeled R is placed between the 4th and 5th tick marks to the left of 0. A point labeled T is placed on the 3rd tick mark to the right of 0.

Maggie's brother is 5 years younger than twice her age. The sum of their ages is 22.
How old is Maggie?
Answer:
9 years old
Step-by-step explanation:
Let maggie's age be m,
and let maggie's brother's age be b
b = 2m - 5,
m + b = 22
Substitute "2m - 5" for b in the second equation (substitution)
m + (2m - 5) = 22 -> Remove parenthesis
m + 2m - 5 = 22 -> Combine like terms
3m = 22 + 5 = 27 -> Divide either side by 3
m = 27/3 = 9
Solution: Maggie is 9 years old

Simplify the following expression.
44[(9 + 3) + 72 - 6 * 2.5 - 19] - [42 - 3(77 + (3.5 2)) - 9]
The value of the expression is 2419.
The required answer is 2400.5
What is simplification?Simplification generally means finding an answer for the complex calculation that may involve numbers on division, multiplication, square roots, cube roots, plus and minus.
Now the given expression is,
44[(9 + 3) + 72 - 6 * 2.5 - 19] - [42 - 3(77 + (3.5 - 2)) - 9]
It can be simplified using PEMDAS rule.
P is parenthesis
E is exponents
M is multiplication
D is division
A is addition
S is subtraction
Firstly we will solve parenthesis, thus
44[(9 + 3) + 72 - 6 * 2.5 - 19] - [42 - 3(77 + (3.5 - 2)) - 9]
= 44[(12) + 72 - 6 * 2.5 - 19] - [42 - 3(77 + (1.5)) - 9]
= 44[12 + 72 - 6 * 2.5 - 19] - [42 - 3(78.5) - 9]
Now we will solve multiplication,
= 44[12 + 72 - 15 - 19] - [42 - 235.5 - 9]
Now we will solve addition,
= 44[84 - 15 - 19] - [42 - 235.5 - 9]
Now we will solve subtraction,
= 44[84 -34] - [42 - 244.5]
= 44[50] - [42 - 244.5]
= 44[50] - [-200.5]
= 2200+ 200.5
= 2400.5
Thus, the required answer is 2400.5

Find the linear function with the following properties.
f(−4)=6
Slope of f=−6
Given:
f(−4)=6
Slope of f=−6
To find:
The linear function with the given properties.
Solution:
We have,
f(−4)=6
It means, the value of linear function is 6 at x=-4. So, the linear function passes through the point (-4,6).
Slope of f=−6
The point slope form of a linear function is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope of the linear function.
On substituting the values, we get
[tex]y-6=(-6)(x-(-4))[/tex]
[tex]y-6=-6(x+4)[/tex]
[tex]y-6=-6x-24[/tex]
Add 6 on both sides.
[tex]y-6+6=-6x-24+6[/tex]
[tex]y=-6x-18[/tex]
The function form of this linear equation is
[tex]f(x)=-6x-18[/tex]
Therefore, the required function is [tex]f(x)=-6x-18[/tex].
