• when x is -1:
[tex]{ \tt{y = 2( - 1) + 3}} \\ { \tt{y = 1}}[/tex]

What is the sum of 2 with exponent of 4 and 7 with an exponent of 2. please write in standard form.
Answer:
I think the answer would be 65 , because :
2^4 + 7^2 = 16 + 49 = 65 .
hope it helps u ^.^
Answer:
65
Step-by-step explanation:
First you would solve the exponent and then you would add them
2 to the power of 4 = 16
7 to the power of 2 = 49
16 + 49 = 65
2 to the power of 4 + 7 to the power of 2 = 65

The equation for the line of reflection is x = 6
What is reflection?An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.
For example, 3x + 5 = 15.
Given that, a graph, we need to find the equation of the reflection of the polygon graphed,
We can see, all the vertices on the polygon are being mirrored across the line x = 6.
So, we can say the line of reflection is x = 6.
Hence, the equation for the line of reflection is x = 6

(5g - 3h) - (6g + 7h)
Answer: -g - 10h
Step-by-step explanation:
(5g - 3h) - (6g + 7h)
= 5g - 3h - 6g - 7h
= 5g - 6g - 3h - 7h
= -g - 10h
An inch is equal to about 2.54 centimeters. Write an expression which estimates the number of centimeters in X inches
Answer: 2.54(x)
Step-by-step explanation:
Since an inch is equal to about 2.54 centimeters, the expression which estimates the number of centimeters in X inches will be gotten by multiplying 2.54 by X. This will be:
= 2.54 × X
= 2.54(x)
For example, if there are 4 inches, the number of centimeters in it will be:
= 2.54(x)
= 2.54 × 4
= 10.16 inches
Find the area of the polygon.
Answer:
120
Step-by-step explanation:
The polygon shown is a parallelogram with a base length of 15 and a height of 8
The area of a parallelogram can easily be calculated by multiplying the height by the base length
So A = 15 * 8
15 * 8 = 120
Hence, the area of the polygon is 120 square units

Answer:
Sam made a mistake. The answer should have been 30.
This is what Sam should have done:
2n^2 - 20
2n^2 - 20 = 2(5)^2 - 20
= 2(25) - 20
= 50 - 20
= 30
Sam multiplied 2 and 5 when he should have done the power first.

not going to worry about it
you would start with the initial amount that she had and then subtract 82x
x=8
so 1250-82x or 82(8)

Calculate the IQR given in the box: 
A child toy is made by removing a triangular prism from the center of a wooden rectangular prism The triangular base of the triangular prism has a base length of 1 inch and a height of 1 inch. Write and solve an equation to find the volume of the toy.
*see attachment for the diagram given
Answer:
Volume of the toy = 68 in.³
Step-by-step explanation:
The equation to find the volume of the toy = volume of the wooden rectangular prism - volume of the triangular prism removed form the center
Volume of the toy = (L*W*H) - (½*bhl)
Where,
L = 8 inches
W = 3 inches
H = 3 inches
b = 1 inch
h = 1 inch
l = 8 inches
Plug in the values into the equation
Volume of the toy = (8*3*3) - (½*1*1*8)
Volume = 72 - 4
Volume of the toy = 68 in.³
solve the system of substitution y=-2x y=5x-21
Answer:
x = 3 is the answerStep-by-step explanation:
1. Write the equation.
y = -2x
y = 5x - 21
2. Substitute the values.
(-2x) = 5x - 21
3. Solve the equation.
-2x = 5x - 21
-5x - 5x
-7x = -21
4. Both negatives cancel
7x = 21
5. Divide both sides by 7
7x = 21
/7 /7
6. x = 3
7. Check the answer.
-2(3) = 5(3) - 21
-6 = 15 - 21
-6 = -6
x = 3 is the answerHope this helped,

if given a radius of 6mm, what is the diameter?
if given a diameter of 22ft, what is the radius?
Answer:
If the radius is 6mm, the diameter is 12mm.
If the diameter is 22 ft, the radius is 11 ft.
Step-by-step explanation:
1st one) When you try to find the diameter of any circle, and you already have the radius, you need to multiply it by two (double it)
6 x 2 = 12mm
2nd one) Then to do the opposite, you need to divide the diameter by 2.
22/2 = 11 ft

find the value of X, round to the nearest 10th
Answer:
4.0731 cm
Step-by-step explanation:
Use pythagorean Theorem which is a^2 + b^2 = c^2 where a and b are the sides of the triangle and c is the hypotenuse, in other words the longest side.
Since x is in line with the center of the circle and is perpendicular with line that measures 15.6 cm we know that one side of the triangle is half of 15.6 or 7.8.
So then we input our known values into the formula and solve for the missing one. The formula looks like this
7.8^2 + b^2 = 8.8^2
solve for b and you get about 4.07431
