Answer:

-3.5 or -7/2

Step-by-step explanation:

To find the slope of a linear line, change it to y=mx+b where m=slope.

7x+2y=5

2y=-7x+5

y=(-7x+5)/2

y=-7/2x+5/2

5/2 is the y intercept(b), it does not affect the slope.

Thus, the answer is -7/2

The rule for h(f(x))
Marat540 [252]

Answer:

h(f(x))=3x-4

Step-by-step explanation:

You combine both F(X) and H(x).

f(x)=x-7 , therefore  it is f(x)=1x-7

You add 2x with 1x  to get  3x

and 7-3 is -4.

h(f(x))=3x-4

Find the value of x. Round your answer to the nearest tenth.
Crazy boy [7]
<h2>The value of x "option A) 12.5" is required answer.</h2>

Step-by-step explanation:

In given figure,

Base (b) = 11 and Angle = 28°

To find, the value of x = ?

We know that,

\cos A=\dfrac{b}{h}

Where, h is the hypotaneous = x

⇒ \cos 28=\dfrac{11}{x}

⇒ x=\dfrac{11}{\cos 28}

The value of \cos 28 = 0.8829

⇒ x = \dfrac{11}{0.8829}

⇒ x = 12.458

⇒ x ≈ 12.5

∴ The value of x ≈ 12.5

Thus, the value of x "option A) 12.5" is required answer.

hram777 [196]
Of 85% of cars sold where not black then 100-85% where black = 15%
let the number of cars sold be y
then 15%*y=300
y= 300 divided by 15%
= (300*100)/15
=2000
therefore 2000 cars were sold
