What are the x and y intercepts for the graph of 4x - 3y = -12
vovangra [49]

x intercept is where the line crosses the x axis or where y=0

y intercept is where the line crosses the y axis or where x=0

x intercept

set y=0

4x-3y=12

4x-3(0)=12

4x=12

divide by 4

x=3

the  x intercept is 3

y intercept

set x=0

4x-3y=12

4(0)-3y=12

-3y=12

divide by -3

y=-4

the y intercept is -4

If ∠1 and ∠2 are complementary and m∠1 = 17º, what is m∠2
Romashka [77]

Answer:

m<2 = 73

Step-by-step explanation:

Since <1 and <2 are complementary (which means that they equal 90), all you have to do is subtract 17 from 90 to find your answer:

90 - 17 = 73

thus, m<2 = 73

What is 7x + 6x = ?<br>​
viva [34]

Answer:

  • 13x

Step-by-step explanation:

<u>Two ways to solve</u>

1.) Expand each term in the equation

  • 7x = x · x · x · x · x · x · x
  • 6x = x · x · x · x · x · x
  • Count all the x’s ⇒ There are 13 x’s ⇒ 13x

2.) Add the coefficients

  • 7 + 6 = 13
  • 7x + 6x = 13x

Hence,

Answer = 13x

Determine rather each equation is there not a equation. Write yes or no. if yes write equation in standard form. -2x-3=y
abruzzese [7]
I don't know about how to put that in standard form, but an equation has to have an equals sign... So, that would be an equation.
