Answer:
a = 9
Step-by-step explanation:
Let's make the demoninators of the 2 fractions the same :
(2a+8)/10 - (5a +15)/10 = 5
(2a + 8 - 5a + 15)/10 = 5
=> -3a + 23 = 50
=> -3a = 27
=> a = 9
The answer is 9 for this question
Answer: b = 69
The slashes mean the opposite angles are the same. This is and isosceles triangle, which mean two sides are the same and one is not.
A triangle = 180
We know one angle is 42 and the other two angles are the same.
Subtract 42 from 180
180 - 42 = 138
Now the 138 is going to two sides but we know they are equal so we can divide 138 by 2
138 divided by 2 = 69
So b = 69
Slope intercept form is y= form
4y+8=0
-8 both sides
4y=-8
÷4 both sides
y=-2
