Answer:
So the y-intercept is 2 while the slope is -7/2.
Step-by-step explanation:
We are going to write this in slope-intercept form because it tells us the slope,m, and the y-intercept,b.
Slope-intercept form is y=mx+b.
So our goal is to solve for y.
-7x-2y=-4
Add 7x on both sides:
-2y=7x-4
Divide both sides by -2:
Separate the fraction:
Simplify:
If we compare this to y=mx+b, we see m is -7/2 and b is 2.
So the y-intercept is 2 while the slope is -7/2.

Answer:
50.528º
Step-by-step explanation:
tanA = BC/BA
tanA = 17/14
A = 50.528º
Geometric series are in the form of
Where a is the first term and r is the common ratio .
And it is given that
r=-3,2
So the first five terms are
= 2-6+18-54+162 or 2+4+8+16+32
= 122 or 62
Answer: Price of Math Textbook= $42.5, Price of the Novel= $11.5
Step-by-step explanation:
Let x = price of the Novel.
Price of Math Textbook = 8+3x
As per given , we have
Price of Math Textbook + Price of the Novel = $54
⇒ 8+3x+x = 54
⇒ 8+4x=54
⇒ 4x = 46 [subtract 8 from both sides]
⇒ x = 11.5
Price of Math Textbook = 8+3(11.5) = 8+34.5= $42.5
Hence, Price of Math Textbook= $42.5, Price of the Novel= $11.5
