Intercepts are when one value is 0...like when x is 0, the point would be the y intercept....
x intercept is 4
y intercept is 5
slope: y2 - y1/x2 - x1
slope = 0 - 5/4 - 0
slope = -5/4
the for the equation plug in any points from the line.
y = mx + b
5 = -5/4(0) + b
5 = B
y = -5/4x + 5 is the equationh to the line
let cat food = x
total plus 5% = 105% = 1.05
1.05 * (11.50 + X) = 16.80
12.075 + 1.05x = 16.80
1.05x = 16.80-12.075
1.05x = 4.725
x = 4.725 / 1.05
x= 4.50
the cat food cost $4.50
11.50 +4.50 = 16.00
16.00 * 0.05 = 0.80
16.00 + 0.80 = 16.80
Answer:
59 degrees
Step-by-step explanation:
law of cosines states that
for sides A B C and angle c opposite to side C,

cos(b) = 
cos-1(23/45) = b
b = 59
Answer:
See attachment
Step-by-step explanation:
We want to show all values of x, for

on the number line.
By the definition of absolute value function:

Divide through the first inequality by -1 and reverse the sign.

On the number line, we can represent this as shown in attachment.
