Answer:

The equation of new line is: \mathbf{y=\frac{3}{4}x-12}

Option H is correct.

Step-by-step explanation:

We need to write an equation for the line that is parallel to the given line y=\frac{3}{4} x-9 and point (-8,-18)

The equation of required line will in in form y=mx+b where m is slope and b is y-intercept.

We need to find slope m and b y-intercept for new line.

Finding slope:

When two lines are parallel, they have the same slope.

The slope of given line can be found by comparing the equation y=\frac{3}{4} x-9 with y=mx+b

So, m = 3/4

The slope of new line will be: m=\frac{3}{4}

Finding y-intercept:

Using slope m = 3/4 and point (-8,-18) we can find y-intercept

y=mx+b\\-18=\frac{3}{4}(-8)+b\\-18=-6+b\\b=-18+6\\b=-12

So, y-intercept is b=-12

The equation of new line having m = 3/4 and b=-12 is:

y=mx+b\\y=\frac{3}{4}x-12

So, the equation of new line is: \mathbf{y=\frac{3}{4}x-12}

Option H is correct.

Question 4. Just replace x with 2a.
So f(2a) = 5(2a)^2 + 4(2a)
= 5*4a^2 + 8a
= 20a^2 + 8a

Question 5. Since x = 3, which is more than 1, use the second equation.
f(3) = 3^2 + 1
= 9 + 1
= 10

Which scenario is modeled by the equation (x)(0.6) = $86.46?
belka [17]

Answer: A picnic table is on sale for 60 percent off. The original price of the picnic table is x, $144.10.


Step-by-step explanation:

Given equation: (x)(0.6)=\$86.46

To find x, divide 0.6 on both sides, we get

x=\frac{\$86.46}{0.6}\\\Rightarrow\ x=\frac{\$864.6}{6}\\\Rightarrow\ x=\$144.10

Also 0.6=0.6\times100=60\%

Thus, 60\%\ of\ \$144.10=\$86.46

So the best scenario modeled by the above equation is

"A picnic table is on sale for 60 percent off. The original price of the picnic table is x, $144.10."

How do you factor 8y^3+316
PilotLPTM [1.2K]
8y^3+316
divide both sides by 4 (smallest divisable number) just say you tried to factor 2 and 3 and they weren't whole numbers and then you tried 4 and gave you the answer :)
4(2y^3+79)

The volume of a cube is V=s3 , where s is the length of one edge of the cube. What is the edge length s for each cube?
PolarNik [594]

Answer:

s = \sqrt[3]{999} }

Step-by-step explanation:

V = s^3

Plug in the given volume.

999 = s^3

Take the third root of both sides to cancel out the ^3.

\sqrt[3]{999} } = s
