Answer:

A linear function has the form y=mx+b

A line has a proportional relationship if y/x is always the same ratio for any value.

The slope m=(y2-y1)/(x2-x1) for some two points on a line is always constant, else it wouldn't create a line.

A line won't be proportional if you adapt b because the ratio of y/x won't match the slope anymore.

In the end this means all lines with proportional relationships must intersect (0,0) or in other words f(0)=0.

This happens if they have the shape y=mx.

For each expression ,use the distributive property to write an equivalent expression
liq [111]
A. 4•x and 4•2 this would turn in 4x+8
B. x•6 and x•8 this would turn into 6x+8x and this equals to 14x
C. 4•2x and 4•3 this would turn into 8x+12.
D. 6•x, 6•y, and 6•z this would equal 6x+6y+6z.

I’m sorry if it’s not clear this is my first answered question.

Question
Mashutka [201]

The equivalent value of given the expression is -17.25. Therefore, option C is the correct answer.

<h3>What is an equivalent expression?</h3>

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

The given expression is -14-8×0.5+0.75.

Now, -14-8×0.5+0.75

= -14-(8×0.5)+0.75

= -14-4+0.75

= -18+0.75

= -17.25

The equivalent value of given the expression is -17.25. Therefore, option C is the correct answer.

Alright.
So, we have 2185 student in Rose.
Lily School has 307 more students than Rose, so Lily has,
2185 + 307 = 2492 Students in Lily School.
Since question a. is asking you to round off to the nearest ten, your answer to part a is 2490.

For part b. add 2185 and 2490.
2185 + 2490 = 4675 students. 
The questions want you to round to the nearest hundredth, so,
4700 is the answer to part b.

Find the surface area of the right prism. Round to the nearest whole number.
andriy [413]

Answer:

\large\boxed{S.A.=96\ cm^2}

Step-by-step explanation:

We have:

(1) two trapezoids with bases b₁ = 7cm and b₂ = 5cm and the height h = 4cm

(2) three rectangles 3 cm × 7 cm, 3 cm × 4 cm and 3 cm × 5 cm.

The formula of an area of a trapezoid:

A=\dfrac{b_1+b_2}{2}\cdot h

Substitute:

A=\dfrac{7+5}{2}\cdot4=24\ cm^2

Calculate the areas of the rectangles:

A_1=(3)(7)=21\ cm^2\\\\A_2=(3)(4)=12\ cm^2\\\\A_3=(3)(5)=15\ cm^2

The Surface Area:

S.A.=(2)(24)+21+12+15=96\ cm^2
