1) does the point (0,4) make either equation true? substitute it in and find out.

The point (0,4) doesn't make either equation true.

Step-by-step explanation:

Consider the equations.

and

We need to determine the point (0,4) make either equation true.

Substitute x=0 and y=4 in

Which is false.

Substitute x=0 and y=4 in

Which is false.

Hence, the point (0,4) doesn't make either equation true.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms
