Help I Will Give Brainliest To The First One To Have A REAL Answer

Answers

Answer 1

Answer:

y = -32

Step-by-step explanation:

-6 (y+15) = -3y + 6

-6y - 90 = -3y + 6

-3y - 90 = 6 + 90

= -3 = 96

y = -32

Answer 2

Answer:

Y=28

Step-by-step explanation:

Distribute-6(y+15) > -6y-90

-6y-90=-3y+6 add the -3y to the -6y and the -90 to the 6

-3y=-84

Then just divide -84 by -3

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

                               Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

What is the y-intercept when a line has a slope of 3 and passes through
the point (2, 7)?

Answers

Answer:

The y-intercept is (0,1)

Step-by-step explanation:

So, first you need to find the equation! Point slope form is (y-y1)=m(x-x1).

Plug the numbers in and you get (y-7)=3(x-2). Now, the y intercept is where x=0, so plug in zero for x.

y-7=3(0-2)

y-7=3(-2)

y-7= -6.

-6+7= 1, so y=1

The ordered pair is then (0,1). Hope this was useful :)

Answers

Answer:

c = 3[tex]\sqrt{6}[/tex]

Step-by-step explanation:

triangle is right isosceles so both sides equal 3[tex]\sqrt{3}[/tex]

can use pythagorean theorem which is square each leg and set it equal to the hypotenuse (side 'c') squared

(3[tex]\sqrt{3}[/tex])^2 +  (3[tex]\sqrt{3}[/tex])^2 = c^2

(9x3) + (9x3) = c^2

27 + 27 = c^2

54 = c^2

c = [tex]\sqrt{54}[/tex]

simplify  [tex]\sqrt{54}[/tex] to equal = [tex]\sqrt{9}[/tex] x [tex]\sqrt{6}[/tex] which simplies to 3[tex]\sqrt{6}[/tex]

Answers

Answer:

a) ∠BAC = 30°b) ∠B = 120°c) ∠BAG = 150°

Step-by-step explanation:

2x + 18 = 5x

18 = 5x - 2x

3x = 18

x = 6

a)  find m∠BAC

substitute x=6 to ∠BAC

∠BAC = 2x + 18

          = 2(6) + 18

          = 30°

b)  find m∠B

∠B = 180 - ∠A - ∠C

    = 180 - 30 - 30

     = 120°

c) find m∠BAG

∠BAG = 180 - ∠A

          = 180 - 30

          = 150°
