Answer:
P = 0.14t +2.25
Step-by-step explanation:
The statement that "the price of a school lunch ... has risen at a constant rate" is telling you that the price can be modeled by a linear equation. If P is the price, and t is years after 2012, you are given two points on the line:
(t, P) = (0, 2.25) and (7, 3.20)
You can use these points to find the equation of the line in the usual way.
m = (y2 -y1)/(x2 -x1) . . . . . . slope of a line through (x1, y1) and (x2, y2)
m = (3.20 -2.25)/(7 -0) = 0.95/7 ≈ 0.14
The first point tells you the equation intercept, so the relationship between P and t is ...
y = mx +b . . . . . . . m = slope; b = y-intercept. We're using (t, P) for (x, y).
P = 0.14t +2.25
Answer:
m>11
Step-by-step explanation:
2*(m+3)-(-5+3*m)<0
STEP1:
2 • (m + 3) - (3m - 5) < 0
STEP2:
11 - m < 0
STEP3:
Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
m-11 > 0
Its a square( same sides)
its a right-angled triangle as half
18²=a²+a²
a=12.73
Answer:
4. -28 ÷ 2
Step-by-step explanation:
Dylan's in debt, so it's -28 dollars. Since he now owes half of what he used to owe, he still is in debt, just not as much as he used to be
Answer:
the answer to your equation is 53/3
Step-by-step explanation:
the easiest way to do it is to multiply the denominator (bottom number of bar line) by the whole number at which it makes it a mixed number, then add the numerator (top number of fraction bar line) to your product.
hope this helped ((; brainliest please !!
