Answer:

x=15

Step-by-step explanation:

the angle 7x+12 and 63 are on opposite sides of complimentary, meaning they add to 180.

180-63 = 117

117-12 = 105

105/7 = 15

Write the equation of the line, in standard form that has an x intercept at (3,0) and y
Nataly [62]
  • x intercept=a=3
  • y intercept=b=-2

We need the normal form first

\\ \rm\bull\rightarrowtail \dfrac{x}{a}+\dfrac{y}{b}=1

\\ \rm\bull\rightarrowtail \dfrac{x}{3}-\dfrac{y}{2}=1

Multiply by 6to bring standard form

\\ \rm\bull\rightarrowtail 2x-3y=1

Answer:

A

Step-by-step explanation:

If we insert the original coordinates into the problem, we will find the answer.

(2+2, 1-5)

so, once solved

(4, -4)

Adding to Y means moving the point up, subtracting to Y means moving down.

17X+1 +20x-14 = 90<br> find x
professor190 [17]

Answer:

x = 2.8

Step-by-step explanation:

17x+1+20x-14 = 90

Combine like terms.

37x-13 = 90

Add 13 on both sides.

37x-13 = 90

     <u>+13   +13</u>

37x = 103

Divide both sides by 37.

37x = 103

<u>/37     /37</u>

x = 2.8

(I rounded up, but if you need a more specific number, just search up 103 divided by 37.)

Hopefully this helps you!! Have an amazing day c:
