Which of the following ordered pairs
make this equation true?
y = 2x - 7
A. (1,9)
B. (-3, 4).
C. (4,1)
D. (-1, 5)

Answer: x=3

Step-by-step explanation:

4^2+b^2=5^2    25-16=9 sqrt of 9 is 3

Answer:

the slope is 2/7 and the intercept is 4

Step-by-step explanation:

In order to find slope, you use the equation delta y over delta x which is the equation, y2-y1/x2-x1.

In this case you plug in each point and get the equation, 2-4/-7-0 or 4-2/0+7.

Simplify to get 2/7.

To find the intercept, you must see what's the y value when x is 0. In this case it's already given to you, so y intercept is 4.

Answer:

115, A

Step-by-step explanation:

The formula to find the total interior angles is   ([number of sides] - 2) x 180, so in this case it would be  540, and     if you subtract all the other interior angles you wi ll get y! (90,135,112,and  88)    (please excuse therandom spaces my spacebar isbroken)

The value of y from the figure is 115 degrees

The given polygon is a pentagon

The sum of an interior angle of the pentagon is 540 degrees

Taking the sum and equating to 540 will give:

90 + 135 + 112 + y + 88 = 540

y + 425 = 540

y = 540 - 425

y = 115 degres

Hence the value of y from the figure is 115 degrees

Answer:

x= 2/3

Step-by-step explanation:

if they are equating,

10x +38 = 40+7x

10x-7x = 40-38

3x = 2

x= 2/3

Answer:

x = 0.6666666667

Step-by-step explanation:

Simplifying

10x + 38 = 40 + 7x

Reorder the terms:

38 + 10x = 40 + 7x

Solving

38 + 10x = 40 + 7x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-7x' to each side of the equation.

38 + 10x + -7x = 40 + 7x + -7x

Combine like terms: 10x + -7x = 3x

38 + 3x = 40 + 7x + -7x

Combine like terms: 7x + -7x = 0

38 + 3x = 40 + 0

38 + 3x = 40

Add '-38' to each side of the equation.

38 + -38 + 3x = 40 + -38

Combine like terms: 38 + -38 = 0

0 + 3x = 40 + -38

3x = 40 + -38

Combine like terms: 40 + -38 = 2

3x = 2

Divide each side by '3'.

x = 0.6666666667

Simplifying

x = 0.6666666667

Step-by-step explanation:

Hope this helps

Answer:

0.80 and 1.30

Step-by-step explanation:

0.80, 1.05, 1.30, 1.55, 1.80, 2.05

... + 0.25 = 1.05

= 1.05 - 0.25

= 0.80

0.80 + 0.25 = 1.05

1.05 + 0.25 = 1.30

1.30 + 0.25 = 1.55

1.55 + 0.25 = 1.80

1.80 + 0.25 = 2.05

Answer:

Pretty sure its 256 in2

Step-by-step explanation:

did the iready test

By decomposing the design into two rectangular prisms, the surface area of the design is calculated as: A. 256 in.²

The surface area of a rectangular prism is expressed as, S = 2(lw + lh + wh).

The design can be decomposed into top rectangular prism and bottom rectangular prism.

The surface area of the design = surface area of the top rectangular prism + surface area of the bottom rectangular prism - 2(area of the top rectangular prism that joins the bottom rectangular prism)

Surface area of the top rectangular prism = 2(lw + lh + wh) = 2(5×4 + 5×4 + 4×4) = 112 in.²

Surface area of the bottom rectangular prism = 2(lw + lh + wh) = 2(8×5 + 8×4 + 5×4) = 184 in.²

Area of the top rectangular prism that joins the bottom rectangular prism = l × w = 5 × 4 = 20 in.²

The surface area of the design = 112 + 184 - 2(20) = 256 in.²
