3 times the product of 5 and b is reduced by 2
3*(5*b)-2
15b-2
Answer:
80 degrees
Step-by-step explanation:
ALL TRIANGLES MUST EQUAL 180 DEGREES!
180-70-30 = 80
Say it with me.
<em>ALL TRIANGLES MUST EQUAL 180 DEGREES!</em>
<em>ALL TRIANGLES MUST EQUAL 180 DEGREES!</em>
<em>ALL TRIANGLES MUST EQUAL 180 DEGREES!</em>
Also, triangle CED reflects over the invisible y-axis. Angle C is shared = 70. Angle E is Angle A, and Angle B is Angle D (which is 80 degrees).
5x - 8y + 104 = 0 is a linear equation passing through (-8 , 8) and parallel to the line whose equation is 5x - 8y - 7 = 0.
First, for two equations of line to be parallel with each other, their slope must be equal.
Transforming the given equation into slope-intercept form, y = mx + b:
5x - 8y - 7 = 0
8y = 5x - 7
y = 5/8 x - 7/8
m = 5/8
Hence, the slope of our equation should also be 5/8.
Using the again the slope intercept form, solve for b.
y = mx + b
where m = 5/8, x = -8 and y = 8
8 = 5/8 (-8) + b
8 = -5 + b
b = 13
With m= 5/8 and y-intercept, b = 13, the equation of our line is
y = mx + b
y = 5/8 x + 13
Multiplying both sides by 8,
8y = 5x + 104
5x - 8y + 104 = 0

Your correct, +1 would give you one point on y line then go down and over to get your slope, so yes you are correct, good job.
