Step-by-step explanation:
Assume that

hence,

now,

attached below is the complete solution
Answer:
= 3x - 3y
Step-by-step explanation:
10(x^2) = 80x
(divide by the 10)
x^2 = 8x
which also equals
(x)(x) = 8x
(divide by x)
x = 8
Answer:
When x=1/2, y=28/3
when x =0, y=9
Equation is y=2/3 x + 9
Step-by-step explanation:
First lets convert them to fractions to make it easier. Also put them in order.
X Y
0
1/2
3/4 19/2
1 29/3
6/5 49/5
You can find the slope since we know 2 points.
(3/4, 19/2) and (6/5, 49/5)
m=3/10 / 9/20
m=2/3
y=2/3 x + b
Lets plug in x and y points to find the y-int
19/2=2/3(3/4) + b
b=9
Therefore y=2/3 x + 9
When x=1/2, y=28/3
when x =0, y=9
Answer:
B 0.6825
Step-by-step explanation:
From the tables
0.80 = 02881 of the area
1.25 = 0.3944 of the area
Sum of these 2 = 0.6825
