Identify the range of the function y=4x-2 domain={-1,-2,-3,-4}

olga55 [171]

Answer:

<h2>The range: {-6, -10, -14, -18}</h2>

Step-by-step explanation:

Put the values of x from the domain to the equation of a function y = 4x - 2:

for x = -1

y = 4(-1) - 2 = -4 - 2 = -6

for x = -2

y = 4(-2) - 2 = -8 - 2 = -10

for x = -3

y = 4(-3) - 2 = -12 - 2 = -14

for x = -4

y = 4(-4) - 2 = -16 - 2 = -18

Help

alisha [4.7K]

Answer:

a. $x^{2} + 3y^{3}$

b. $3y^{3} -6$

c. $5x -3$

d. -6t - 5

Step-by-step explanation:

When a number has the same variable as another, you can add or subtract them

So for the first one, you can do

$5x^{2} -4x^{2} = 1x^{2} = x^{2}$

(But don't forget the $3y^{3}$ !)

So it is:

$x^{2} + 3y^{3}$

Continue this process for the rest of them

What is the measure of x in degrees ?

mr Goodwill [35]

Answer:

x = 35°

Step-by-step explanation:

Same side interior angles are supplementary, or they add up to 180°. So write an equation:

$x+145=180$

Solve for x. Subtract 145 from both sides:

$x+145-145=180-145\\\\x=35$

The value of x is 35°.
