Answer:
C
Step-by-step explanation:
Alright so for this one they want us to find the x values of angle 3 and angle 5 and those 2 angles happen to be supplementary meaning that the two angles will add up to equal 180. So to setup the equation we do
180 = 5x+10+3x+10
step 1 combine like terms ( 5x +3x and 10 + 10)
180 = 8x +20
step 2 subtract each side by 20
160 = 8x
step 3 divide each side by 8
x=20
The equation is y= 1.5x+38.5 and the value of y-intercept is 38.5
What is slope and y-intercept?
- The values of the slope and y-intercept reveal details of the relationship between the two variables, x and y.
- The slope shows how quickly y changes for every unit change in x. When the x-value is 0, the y-intercept shows the y-value.
Standard form of a slope intercept form is
y= mx+c
here m is slope. This is rate of y increases as x increases by 1,
C is y intercept, this is the value of y at start(when x=0).
Here y is amount collected. Here we have 38.5 at start. So C= 38.5
In each week amount (y) increases by 1.5. So m=1.5
Substitute in the standard form: Then,
y= 1.5x+38.5
Hence, the equation is y= 1.5x+38.5 and the value of y-intercept is 38.5

Ok so you would times 8.4*10 and get 84-6 which is 78, and 6.5*10 which is 65-6, so then you get 78+59=137 :)
