Answer:
a) upward
b) x-intercepts at x= -4, -2
y-intercept at y = 8
c) x = -3
d) (-3, -1)
Step-by-step explanation:
after the answer to the other, very similar question you should be really able to do this one.
all is really visible.
please refer to my other answer for more details about the reasons.
Write and solve an equation of ratios:
8 cups OJ 18 cups punch
-------------- = --------------------
x 108 cups
Cross mult.: (8)(108) = 18x. Dividing both sides by 18, x = 48 (answer)
Answer:
h(n+1) = h(n) - 7
Step-by-step explanation:
Our objective is to write the expression for h(n+1) in terms of h(n) which equals -31 -7(n-1)
So we use the given formula to find what h(n+1) is:
h(n+1) = -31 -7((n+1)-1)
h(n+1) = -31 -7(n+1-1)
we now re-arrange the order of terms inside the parenthesis without combining like terms:
h(n+1) = -31 -7(n-1+1)
and use distributive property to multiply "-7" times the "+1" term and get it extracted from inside the parenthesis:
h(n+1) = -31 -7(n-1) -7
Notice that this way we were able to preserve the form of the term h(n) "-31 -7(n-1)" , and see what is the modification introduced to it when finding the term h(n+1). We now replace "-31 -7(n-1)" by "h(n)" in the above equation:
h(n+1) = -31 -7(n-1) -7
h(n+1) = h(n) - 7
And this is the recursive formula that tells us how to construct the following term of a sequence by knowing the previous one.
Answer:
$24.375
Step-by-step explanation:
Regular price of sandals = $32.50
Store sells sandals for 25% of the regular price.
Hence selling price =(100-25)% of the regular price.
In other words, selling price = 75% of regular price
= 75% of $32.50
=
=
Hence the sale price of the sandals is $24.375
This is $8.125 less than the regular price of the sandal.
