If you would like to calculate A + B and B - A, you can do this using the following steps:
A = 3 * X - 2
B = - 6 * X - 7
A + B = (3 * X - 2) + (- 6 * X - 7) = - 3 * X - 9
B - A = (- 6 * X - 7) - (3 * X - 2) = - 9 * X - 5
The correct result would be B.
Answer:
To find the length of a horizontal line segment, find the difference between the x-coordinates. Subtract the smaller from the larger.
slope (m) = rate. $40 per hour is the rate, so m = 45
y-intercept (b) = one time fee. $45 is the flat rate which is the one time fee, so b = 45
y = mx + b
y = 40x + 45
Answer: A
Answer:
(-5 , 0)
(-2, 0)
(0, 20)
Step-by-step explanation:
y = 2x² + 14x + 20
x intercepts occur when y = 0
0 = 2x² + 14x + 20
0 = (2x + 4)(x + 5)
x = -5
or
x = -2
y intercept occurs when x = 0
y = 2(0)² + 14(0) + 20
y = 20
Answer:
g = 2d - 8
g + d = 46
Step-by-step explanation:
It is given that the guitarist wrote eight less than twice as many songs as the drummer did, hence one would multiply by the number of songs the drummer wrote by two, and subtract eight.
It is also given that the combined total of songs that they both wrote is 46, hence one would add up the songs that they wrote, and attain a result fo 46.
