Answer:
A) 20 represents the amount of money saved in one month or amount saved per month. This is the slope or rate of change of the function.
B) 50 represents the amount of money already present in the account when she starts saving. This is the y-intercept of the function.
C) It will take 5 weeks for her to save $150
Step-by-step explanation:
A) 20 represents the amount of money saved in one month or amount saved per month. This is the slope or rate of change of the function.
B) 50 represents the amount of money already present in the account when she starts saving. This is the y-intercept of the function.
C) The time to reach $150
150 = 20(w) + 50
20(w) = 150 - 50
20w = 100
w = 100/20
w = 5
It will take 5 weeks
Answer:
f(-3) = -4
Step-by-step explanation:
f(x) = -2x² - 3x + 5
f(-3) = -2(-3)² - 3(-3) + 5
f(-3) = -2(9) + 9 + 5
f(-3) = -18 + 9 + 5
f(-3) = -9 + 5
f(-3) = -4
-3(-15w+2)
You have to use the distributive property to simplify this expression.
-3 times -15w is 45w.
-3 times 2 is -6.
-3(-15w+2)
45w-6 is the answer
Answer:
Around 8 or 9
Step-by-step explanation:
210/ 24= 8.75
if ur rounding then the answer is 9
Since those two triangles are similar by AA
then use proportions to get "x"
thus
hmmm wait just a second? what the dickens is WU anyway?
well, let's take a look at the triangle on the right-side
is a right-triangle, has a 90° angle
so, just use the pythagorean theorem to get WU
which will give you
solve for "x"
