Answer:
5 and 25
Step-by-step explanation:
let the son's age be x then the father's age is x + 20
In 5 years
son = x + 5 and father = x + 20 + 5 = x + 25
Then
x + 25 = 3(x + 5) ← father is three times as old as son
x + 25 = 3x + 15 ( subtract x from both sides )
25 = 2x + 15 ( subtract 15 from both sides )
10 = 2x ( divide both sides by 2 )
5 = x and x + 20 = 5 + 20 = 25
si=on is 5 and father is 25
Divide by 3 bring it down by the 20th and bring the second one down
Answer:
B. y = x² - 3x - 10
Step-by-step explanation:
<em>good luck, i hope this helps :)</em>
Step-by-step explanation:
Simplify :
x4−6x3+2x−7+7x3−x+5x2+2−x4
x4−6x3+2x−7+7x3−x+5x2+2−x4
Rearranging and collecting the like terms, we get:
=(x4−x4)+(−6x3+7x3)+5x2+(2x−x)+(−7+2)
=(1−1)x4+(−6+7)x3+5x2+(2−1)x+(−7+2)
=(1)x3+5x2+(1)x−7+2
=x3+5x2+x−5
Hi There!
Follow y = mx + b
m = slope
b = y intercept
(a) What are the slope and the y-intercept for the equation that represents the number of baskets of berries the workers picked over a period of time?
Slope = 5
Y intercept = 10
(b) What are the rate of change and the initial amount? Explain the meaning of the rate of change and the initial amount for the situation.
The rate of change is how much it takes for the amoun to change. The initial amount should be going up with a slope of 5 each time.
(c) Use graph paper to draw a graph representing the situation. Label the axes appropriately.
Start at the origin than continue with a slope of 5 and make sure the y intercept is correctly graphed.
