Solve the following system of equations graphically. y - 4 = 0 2x - y - 2 = 0 What is the solution set?

Answer:

{ $(x,y)|(x=3,y=4)$ }

Step-by-step explanation:

The given system of equations is;

$y-4=0...(1)$

and

$2x-y-2=0...(2)$

We rewrite the equations in the standard form to get:

$y=4...(3)$

$2x-y=2...(4)$

We now substitute equation (3) into equation (4) to get:

$2x-4=2$

Group similar terms:

$2x=2+4$

$2x=6$

Divide both sides by 2

$\frac{2x}{2}=\frac{6}{2}$

This implies that:

$x=3$

Therefore the solution set is:

{ $(x,y)|(x=3,y=4)$ }

The parent function of the function represented in the table is exponential.

Note if you subtract 10 from each output, you get $f(x)=3^x$ .

If function f was translated down 4 units, the f(x) values would be decreased by 4.

See attached image.

A point on the table for the transformed function would be (4, 87).

$f(4)-4=87$

Step-by-step explanation:

$\sf \left(-7c+8d\right)\cdot \:0.6$

$\sf 0.6\left(-7c+8d\right)$

Apply distributive property

$\sf 0.6\left(-7c\right)+0.6\times \:8d$

$\sf -4.2c+4.8d$

Have a good day!
