Answer:

x=12

Step-by-step explanation:

Supplementary angles add up to 180 degrees.

10x+60=180

Subtract 60 from both sides:

10x=120

Divide 10 to both sides:

x=12

Answer:

x=12

Step-by-step explanation:

By definition, supplementary angles add up to 180 degrees. Therefore, we can set up the follow equation to solve for x:

10x+60=180,\\10x=120,\\x=\boxed{12}

Answer:

Step-by-step explanation:

y - 3 = 1/4(x - 4)

now use algebra to get the above point-slope formula in the slope-intercept formula

y - 3 = 1/4(x - 4)

y - 3 = 1/4x -1

y = 1/4x +2

now that you have the slope-intercept form graph it

Rewrite the function y= x^2 + 14x + 4 in vertex form
Step2247 [10]
Vertex form is basically commplete the square
y=a(x-h)^2+k


y=x^2+14x+4
take 1/2 of 14 and square it, (7^2=49)
add that and its negative to right side
y=x^2+14x+49-49+4
factor perfect squaer
y=(x+7)^2-49+4
y=(x+7)^2-45

answer is A
