Ƒ2 + 8 if ƒ = 7? Please help, LOL.

Nata [24]

Answer:

Step-by-step explanation:

If f is equal to 7, you'd multiply 7 by 2 (following pemdas/gemdas). When you multiply those two numbers, you get 14. If you add 8 to 14 you get 24.

Find the equation of the line using the point-slope formula. Write all the final equations

vivado [14]

Answer:

$y=\frac{1}{2}x+\frac{5}{2}$

Step-by-step explanation:

We are going to find the slope by lining up the points vertically and subtract, then put 2nd difference over first.

Also you could just use $\frac{y_2-y_1}{x_2-x_1}$ . It is the same thing.

( 5 , 5)

-( 1 , 3)

--------------

4 2

So the slope is 2/4 or 1/2 after reducing.

The point-slope form a line is

$y-y_1=m(x-x_1)$ with a point on the line $(x_1,y_1)=(1,3)$ given and with slope $m=\frac{1}{2}$ given.

$y-3=\frac{1}{2}(x-1)$

We are going to solve this for y and simplify what we can because our goal is y=mx+b; this is slope-intercept form. It is called that because it tells us the slope,m, and the y-intercept,b.

Distribute:

$y-3=\frac{1}{2}x-\frac{1}{2}$

Add 3 on both sides:

$y=\frac{1}{2}x-\frac{1}{2}+3$

Simplify:

$y=\frac{1}{2}x+\frac{5}{2}$

5x+6y=13 and -5x+2y=11

murzikaleks [220]

$6y = 13 + 2y = 11$
$4y = 13 + 11$
$4y = 24$

$24 \div 4 =$
$6$
