Answer:The b is 15.7-2(a)
Step-by-step explanation:
2a+b=15.7
b=15.7-2a
The length will be a+a which is greater than length of b
The b is 15.7-2(a)
That would be 12*2 + 10*2 = 24 + 20 = 44 feet
Slope (m) = change in Y over change in X
change in Y = 9-5 = 4
change in x = 8-4 = 4
slope = 4/4 = 1
m = 1
the y intercept (b) would be found by using the formula y = mx+b
find b by replacing y, m and x in the equation with one of the points and the calculated slope:
(4,5) x = 4, y = 5 and slope m = 1
5 = 1*4 +b
5 = 4+b
b = 5-4
b=1
so the equation of the line would be y = x +1
the answer is A
Answer:
x = -12
Step-by-step explanation:
Let x be the number.
The product of 5 and x increased by 9 is equal to 15 less than 3 times x.
5x + 9 = 3x - 15.
We can isolate x, getting (5-3)x = -15-9
Then we can solve:
2x = -24
x = -12.
Answer:
The answer should be 16 because they gained 14 yards, then they lost 7 yards, and finally they gained 9 yards.
14 -7 + 9 = 16
