r+b =12
r =2b (twice as many red as blue)
substitute r = 2b into r+b=12
2b + b = 12
3b =12
divide by 3
b=4
r = 2b
r=2(4)
r=8
There are 4 blue pencils and 8 red pencils
We have the following product:
-2x ^ 2y ^ 3 · 14x ^ 2y ^ 3
For power properties we have:
"same base add the exponents"
We have then:
(-2 * 14) (x ^ (2 + 2)) (y ^ (3 + 3))
-28x ^ 4y ^ 6
Answer:
The product -2x ^ 2y ^ 3 · 14x ^ 2y ^ 3 is:
-28x ^ 4y ^ 6
Answer:
B
Step-by-step explanation:
The red graph is a horizontal translation of 5 units left, followed by a reflection in the x- axis, of the black graph.
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then shift to the left of a units
• If a < 0 then shift to the right of a units
Here the graph is shifted 5 units to the left, thus
f(x) → f(x + 5)
Under a reflection in the x- axis
a point (x, y ) → (x, - y )
Note the y- coordinate of the image is the negative of the original
Note that 
= - y, thus
The equation of the red graph is
= f(x + 5) → B
Answer:
x is the number of miles
Step-by-step explanation:
Because the per mile charge is $2.65 per mile .. so for x miles, the per mile charge is 2.65x. And the fixed charge is the initial charge of $2.50.
y = 2.50 + 2.65x
Answer:
24.
Step-by-step explanation:
So you need to fine 30% of 80.
I did the following method:
-Break it down, and do, 80 -/- 10 which is 8, now you have 10%, and you need to find 30, times your 10% by 3, so 24.
-Therefore, 24 out of 80 rides at the amusement park are water-related.
Hope this helps!
