23) Store A: y=6.30÷2
y=3.15
Store B: y=3.2
Store C: y=3.25x
y=3.25 so Store A sells the cheapest so (A) is the answer
24) the area uses half of the diameter, not the whole diameter. so the answer is 5.5pi^2 (B)
25) 1/2 × 1/2 = 1/4 × 1/2 = 1/8 (D)
26) was done correctly and (D) is the correct answer
27) 2 (x-3) +1 =19
2 (x-3) = 19 - 1
(x-3) = 18 ÷ 2
x-3 = 9
x= 9+3
x=12 (D)
Answer:
3, - 2, - 7, - 12, - 17, - 22
Step-by-step explanation:
To find the first 6 terms substitute n = 1, 2, 3, 4, 5 into the formula, that is
t(1 + 1) = t(1) - 5 ⇒ t(2) = 3 - 5 = - 2
t(2 + 1) = t(2) - 5 ⇒ t(3) = - 2 - 5 = - 7
t(3 + 1) = t(3) - 5 ⇒ t(4) = - 7 - 5 = - 12
t(4 + 1) = t(4) - 5 ⇒ t(5) = - 12 - 5 = - 17
t(5 + 1) = t(5) - 5 ⇒ t(6) = - 17 - 5 = - 22
You put number nine in the form of y=kx
Answer:
slope: -11/7
Step-by-step explanation:
Slope is equal to the change in yy over the change in xx, or rise over run.
m=change in ychange in xm=change in ychange in x
The change in xx is equal to the difference in x-coordinates (also called run), and the change in yy is equal to the difference in y-coordinates (also called rise).
m=y2−y1x2−x1m=y2-y1x2-x1
Substitute in the values of xx and yy into the equation to find the slope.
m=19−(8)−9−(−2)m=19-(8)-9-(-2)
Simplify.
m=−11/7
