2(y + 3) + 2(4 - y) HELP ME
Answer:
14
Step-by-step explanation:
1. Distribute
2(y + 3) + 2(4 - y)
2 + 6 + 2(4 − )
2. Rearange terms
2y + 6 + 2(4 - y)
2 + 6 + 2(- + 4)
3. Distribute
2y + 6 + 2(-y - 4)
2y + 6 - 2y + 8
4. Add numbers
2y + 6 - 2y + 8
2y + 14 - 2y
5. Combine like terms
2y + 14 - 2y
14
6. Solution

can i be brainiest...
Answer:
the answer is 14y
Step-by-step explanation:
this is because if you multiply 2xy it is 2y then multiply 2x3 and that's 6. Then you add 6+2y and get 8y. Next you multiply 2x4 which is 8 then 2xy which is 2y. Next you subtract 8-2y which is 6y. then you add 6y+8y and you answer is 14y.
Which of the following is a quadratic function?
f(x) = 0x + 3x - 6
f(x) = 2x + 5
f(x) = 3 - 4x^2

Marco is interested in the number of penguins who live on a particular ice floe. He decides to take an aerial photo of
the floe and create a 20 by 20 grid on the photo. He randomly selects 3 cells and counts the number of penguins in
each. He then finds the mean number of penguins for those 3 cells. Marco repeats this process for a total of 50
samples and makes a dotplot of the 50 means. This graph is an approximation of
O stratified random sampling.
the distribution of sample data.
the distribution of the population.
the sampling distribution of means.
the sampling distribution of proportions,
M
Answer: D
Step-by-step explanation: In this experiment, the researcher, Marco first collectd the data values, then computes the sample means and finally obtains the sampling distribution of sample means.

What is the value of x in the equation 3/4 x + 24 = x − 12 ?
Answer:
x = 144
Step-by-step explanation:
3/4x + 24 = x - 12
3/4x - x = -12 - 24
3/4x - 4/4x = -36
-1/4x = -36
x = -36/-1/4
x = 144

Answer:
a = 8, b = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given the exponential function
f(x) = a[tex]b^{x}[/tex]
To find a and b use the given coordinate points on the graph
Using (0, 8 ), then
8 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ] , then
a = 8
f(x) = 8[tex]b^{x}[/tex]
Using (2, 18 ) , then
18 = 8b² ( divide both sides by 8 )
[tex]\frac{18}{8}[/tex] = b² , that is
b² = [tex]\frac{9}{4}[/tex] ( take the square root of both sides )
b = [tex]\sqrt{\frac{9}{4} }[/tex] = [tex]\frac{3}{2}[/tex]
Thus
f(x) = 8[tex](\frac{3}{2}) ^{x}[/tex]
a line that includes the point (5, 1)and has a slope of 1

which of the following is not a factor of 4x^3+12x^2-72x? a.(x+9) b.(x-3) c.4x d.(x+6
Answer:
x+9
Step-by-step explanation:
4x³+12x²-72x
=4x(x²+3x-18)
=4x[x²+6x-3x-18]
=4x[x(x+6)-3(x+6)]
=4x(x+6)(x-3)

What is your question?
8/9 divided by 5? :’)
Answer:
8/45 or 0.177...... (the seven continues forever).
Step-by-step explanation:
8/9 ÷ 5
First, turn 5 into a fraction. That will be 5/1
8/9 ÷ 5/1
When you're dividing fractions, you flip the second fraction and turn the division sign to a mutiplication sign
8/9 ÷ 1/5
8/9 * 1/5
Now you multiply. We will multiply the numerator and then the denominators through since there are no common factors.
8 * 1/9 * 5
8/45
