The y intercept (b) is where is crosses the y axis = 5
The x intercept is where is crosses the x axis = 4
The slope is rise over run or y2 - y1/x2 - x1
m = 0 - 5/4 - 0
m = -5/4
y = mx +b
y = -5/4x + 5
Let f(x)=ax+b
11a+b=23.55
12a+b=25.35
solve: a=1.8 b=3.75
so ..
f(x)=1.8x+3.75
if x=31 , f(x)=59.55
Answer:
50,000 $
Step-by-step explanation:
Since its 8th , 9th , 10th, 11th, and 12th grade that's 5 years of throughout high school, so once he graduated high school Christopher ended up with 50,000 $. (5 × 10,000)
Here you go:
h = 5 x 2.54
please correct me if I'm wrong,
Hope it helps!
We can use ratios and the cross-multiply-divide to find this.
The ratio 21:5 is avaliable via the question. We then need to compare that to the ratio x:100, the 100 being the percent and the x being the number of airplane parts.
21/5 = x/100
We can then solve for x to find the number of airplane parts. First we multiply by 100 on both sides to get 2100/5 = x. Therefore x = 420 and there are 420 airplane parts.
