Answer:70
Step-by-step explanation:
10^2 =100
-2(10+15) = -2(15)=-30
100-30= 70
First, multiply. 7x-14-4x+9. Now, add the like terms. 3x-5.
Answer:
y= -2/3x+10
Step-by-step explanation:
-2/3=slope, x-intercept=5 = (5,0)
formula is y-y1=m(x-x1)
(5,0) ---> 5=x1 0=y1
y-0= -2/3(x-5)
y-0= -2/3x+10
+0 +0
y= -2/3x+10
3x° is 60° , 2x° is 40° and 4x° is 80°

How to determine the angles</h3>
Note that the sum of angles in a triangle is 180°
Solve for x in the triangle
Then,
3x° +2x° + 4x° = 180°
Add the x°
9x° = 180°
Divide both sides by 9
x° = 180÷ 9 = 20°
If x° = 20
Then 3x° = 3× 20 = 60°
2x° = 2 × 20 = 40°
4x°= 4× 20 = 80°
Therefore, 3x° is 60° , 2x° is 40° and 4x° is 80°
