Answer:
59°
Explanation:
If you add the angles 99° from angle C in the top shape and add 22° on the bottom shape it will give you 121°. When you get this subtract it from 180°
180°-121°= 59°
So, it's 58°
You can check by adding 180°+121°+59° = 180°

Answer:

Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have two standard form equations which we will get a slope and a y-intercept from. We will convert each to slope intercept form to get the information. We will then write a new slope-intercept equation and convert to standard form.
3x-5y=7 has the same slope as the line. Let's convert.


The slope is
.
2y-9x=8 has the same y-intercept as the line. Let's convert.


The y-intercept is 4.
We take
and b=4 and substitute into y=mx+b.

We now convert to standard form.

For standard form we need the coefficients of x and y to be not zero or fractions. We need integers but the coefficient of x cannot be negative. So we multiply the entire equation by -5 to clear the denominators.

(a) d=days C=cost
d C
1 30
2 40
3 50
4 60
C=10(d-1)+30
(b) C=10(5-1)+30
C=40+30
C=70
