Answer:
2x + 2y = 4 does not belong
Step-by-step explanation:
2x + y = 4 → y = -2x + 4
y = -2x + 4 → y = -2x + 4
f(x) = -2x + 4 → y = -2x + 4
2x + 2y = 4 → y = -x + 2

Does the point (–3, 4) satisfy the equation y = –2x + 5? Yes Or No
Answer:
No
Step-by-step explanation:
y = -2x + 5
4 = -2(-3) + 5 - Substitute both x and y
4 = 6 + 5 - Simplify
4 ≠ 11
Hence, no, (-3, 4) doesn't statify the equation y = -2x + 5
The hypotenuse of a right triangle is 7 feet long. One leg is 4 feet longer than the other. Find the lengths of the legs, Round to the nearest tenth of a foot
The length of the shorter leg is ft, and the length of the longer leg is ft.
(Do not round until the final answer. Then round to the nearest tenth as needed)
Help Me Solve This
View any
Answer:
Shorter leg = 2.5 ft.
Longer leg = 6.5 ft.
Step-by-step explanation:
a^2 + b^2 = c^2
Because the hypotenuse = 7 ft, a^2 + b^2 = 49
To represent the two legs, we can use x and x+4.
x^2 + (x+4)^2 = 49
Simplifying this equation using FOIL gives us 2x^2 + 8x - 33 = 0.
Then, using the quadratic formula, we find that x = 2.5.
Thus, the shorter leg is 2.5 ft. and, when 4 is added, the longer leg is 6.5 ft.

X-(-y-z+3) remove the parentheses
Answer:
x + y + z - 3
Step-by-step explanation:
Basically, putting a negative sign before parentheses signifies that you want to flip the sign of everything within the parentheses. This can also be explained by the negative sign representing -1.
Knowing this, we can just multiply everything within by -1.
-y -> y
-z -> z
3 -> -3
We now have y + z - 3, just put this into the original expression and we have our final answer of:
x + y + z - 3

Round the number 245,382 to the nearest given place value.
13. hundred
14. ten-thousand
16. ten
15. thousand
The value of each digit in a number is known as the place value. The number 245,382 to the nearest hundred place value is 245,400.
What is the place value of a digit in a number?The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.
The given number 245,382 can be rounded off to the nearest given place values as,
A.) hundred
The hundred is the third place in any number from the right end since the second value is 8 which is close to 10, therefore, the hundred place value will be rounded off to the next number.
245,400
B.) ten-thousand
The ten-thousand is the fifth place in any number from the right end since the fourth value is 5 followed by 382 which is more close to 50,000 than 40,000 , therefore, the ten-thousand place value will be rounded off to the next number.
250,000
C.) ten
The ten is the second place in any number from the right end since the first value is 2 which is close to 0, therefore, the ten place value will be the same while the first place will become zero.
245,380
D.) thousand
The thousand is the fourth place in any number from the right end since the third value is 3 which is close to 0, therefore, the thousand place value will be the same while the third place and the ahead will become zero.

When you want to multiply 2 fractions, merge the fractions together & then multiply the numerator first & then the denominator. After that, simplify to the lowest form if possible.Members of a softball team raised $1319.25 to go to a tournament. They rented a bus
for $776.50 and budgeted $41.75 per player for meals. Write and solve an equation
which can be used to determine p, the number of players the team can bring to the
tournament. Giving 100 points please help
Answer:
13 players
Step-by-step explanation:
Money Raised=RentedBus+Meals
1319.25=776.50+41.75p (p is for the number of players)(Now we solve for x)
Subtract 776.50 from both sides: 542.75=41.75x
Divide both sides by 41.75: 13=x
Remember that x is for the number of players so there'll be 13 players going to the tournament.

I need help to find the side
Answer:
x = 10.55cm
Step-by-step explanation:
Sin 29 degrees = 7cm/x
X = 7cm / sin 29
= 10.55 cm
Answer:
x =14.4cm
Step-by-step explanation:
Sin x = opp/hyp
This is because we are given angle look into the triangle and see opp given =7 and need hypotenuse
Sin x = 7 / sin (29) = 14.4386574 cm = 14.4cm
This is because the opp is the 7 measure.
x = 14.4cm
We can prove the base is less through Pythagoras theorem
simply as c^2-b^2 = a^2
14.4386.....^2 -7^2 = c^2
sqrt 208.47 - sqrt 49 =c^2
c^2 = sqrt 159 = 7.43849023
therefore base = 7.44
To check angle 29 degrees for 3rd proof
cos (29) x 7/x= (x)
= 203 / x
check 203/29 = 7
Given a=7 and ∠α=29°,
b = 12.62833
c = 14.43866 proof
∠β = 61°
h = 6.12234
area = 44.19917
perimeter = 34.06699
inradius = 2.59484
circumradius = 7.2193
Write an equation for the line that passes through the given point and is parallel/perpendicular to the graph of the given point.
Parallel: Y=3x-2; (3,2)
Perpendicular: Y= -2x-1; (2,-1)
Also I will mark brainly to who explain what they did step by step
Answer:
Parallel: The slope is the same as in the previous equation. So, y=3x+b. To find the value of b, you plug in the given point, 2=3(3)+b, b=-7. So the equation is y=3x-7.
Perpendicular: The slope is the negative reciprocal when an equation is perpendicular. The negative reciprocal of -2 is 1/2. So, y=1/2x+b. To find the value of b, you plug in the given point, -1=1/2(2)+b, -1=1+b, b=-2. So the equation is y=1/2x-2.

Answer:
parallel: y = 3x -7perpendicular: y = 1/2x -2Step-by-step explanation:
The given line equations are written in "slope-intercept" form.
y = mx + b . . . . . . . . . m is the slope; b is the y-intercept
If we solve this equation for b, we find ...
b = y - mx
This is useful for completing the equation of the line through a given point when the slope is known.
ParallelA parallel line will have the same slope as the given line. The given line has a slope (x-coefficient) of 3. We can find the "b" of the line through the desired point as ...
b = y -3x
b = 2 -(3)(3) = -7
The equation of the parallel line is ...
y = 3x -7
__
PerpendicularA perpendicular line will have a slope that is the opposite reciprocal of the slope of the line it is perpendicular to. Here, the given line has a slope of -2, so the perpendicular line will have a slope of ...
-1/(-2) = 1/2
Then the y-intercept is ...
b = y -(1/2)x
b = -1 -(1/2)(2) = -2
And the equation of the perpendicular line is ...
y = 1/2x -2

solve the following inequality for n -5n+6≥-7(5n-6)-6n
Answer: The inequality is: n ≥ 36/37
Step-by-step explanation:
Let's solve your inequality step-by-step.
n − 5n + 6 ≥ −7(5n−6)−6
----------------------------------------------------------------------------------------------------------------
Step 1: Simplify both sides of the inequality.
−4n + 6 ≥ −41n + 42
----------------------------------------------------------------------------------------------------------------
Step 2: Add 41n to both sides.
−4n + 6 + 41n ≥ − 41n+ 42 + 41n
37n + 6 ≥ 42
----------------------------------------------------------------------------------------------------------------
Step 3: Subtract 6 from both sides.
37n + 6 − 6 ≥ 42 − 6
37n ≥ 36
----------------------------------------------------------------------------------------------------------------
Step 4: Divide both sides by 37.
37n/37 ≥ 36/37
n ≥ 36/37
----------------------------------------------------------------------------------------------------------------
Answer:
n ≥ 36/37

The fraction spent altogether on food and clothes is 7/12.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
Fraction of earnings spend on food:
= 1/3
Fraction of earnings spend on clothes:
= 1/4
Fraction of total spending on food and clothes.
= 1/3 + 1/4
= (4 + 3) / 12
= 7/12
The formula for adding two fractions:
= a/b + c/d
= (ad + bc) / cd
Fraction of earnings saved after spending on food and clothes.
= 1 - 7/12
= (12 - 7) / 12
= 5/12
Thus,
The fraction spent altogether on food and clothes is 7/12.
