Given h(x) = 5 - 9x, find h(8).
Answer:
h(8)=-67
Step-by-step explanation:
We know that x=8 so we solve the solution on the right by replacing x with 8
5-9*8
5-72
-67
So h(8)=-67

Answer:
(3, 10, 17, 24....)
Step-by-step explanation:
f(x) = 7x - 4
x = 1:
f(1) = 7*1 - 4 = 7 - 4 = 3
x = 2:
f(2) = 7*2 - 4 = 14 - 4 = 10
x = 3
f(3) = 7*3 - 4 = 21 - 4 = 17
then the sequence is:
(3, 10, 17, 24.....)

Answer:
D
Step-by-step explanation:
So we have the equation:
[tex]A=\frac{1}{2}(12)(3+7)[/tex]
And we want to find out which of the answer choices is not equivalent.
Thus, let's go through each of the choices.
A)
We have:
[tex]\frac{12(3+7)}{2}[/tex]
This is correct.
Our original equation can be written as:
[tex]A=\frac{1}{2}(\frac{12(3+7)}{1})[/tex]
And if we multiply straight across:
[tex]A=\frac{12(3+7)}{2}[/tex]
We'll get choice A. So choice A is correct.
B)
We have:
[tex]6(3+7)[/tex]
This is also correct.
From our original equation:
[tex]A=\frac{1}{2}(12)\cdot(3+7)[/tex]
If we multiply the first term together:
[tex]A=6(3+7)[/tex]
We'll get choice B. So, choice B is correct.
C)
We have:
[tex]0.5(12)(10)[/tex]
This is correct as well.
If we reduce 1/2 to decimal form and add the operations within the parentheses in the original equation, we will get:
[tex]A=\frac{1}{2}(12)(3+7)\\A=0.5(12)(10)[/tex]
So, C is also correct.
D)
We have:
[tex]\frac{12}{2}\times\frac{10}{2}[/tex]
Note that this is not correct.
This attempted to use the distributive property. However, the distribute property does not work for multiplication. For instance:
[tex]3(2+1)\text{ indeed equals } 3(2)+3(1)[/tex]
However:
[tex]3(2\times1)\text{ does not equal} 3(2)\times3(1)[/tex]
So, choice D is not equivalent.
So choice D is our answer :)

Evaluate j/4 when j=12
Answer:
3
Step-by-step explanation:
[tex] \frac{j}{4} = \frac{12}{4} = 3[/tex]
4*3=12
3*4=12
12/4=3
12/3=4
Hope this helps ;) ❤❤❤
Answer:
We need to evaluate [tex]\frac{j}{4}[/tex] for j = 12.
First, we need to replace j by 12 on [tex]\frac{j}{4}[/tex], so we get [tex]\frac{12}{4}[/tex] and now, we only need to divide:
[tex]\frac{12}{4}=3[/tex]
So the result is 3

Step-by-step explanation:
[tex]2\frac{5}{7}+4\frac{3}{5}[/tex]
add the whole numbers
[tex]2+4=6[/tex]
combine the fractions
[tex]\frac{5}{7}+\frac{3}{5}[/tex]
LCM is 35 because 7 * 5 =35
[tex]\frac{5}{7}=\frac{5\cdot \:5}{7\cdot \:5}=\frac{25}{35}[/tex]
[tex]\frac{3}{5}=\frac{3\cdot \:7}{5\cdot \:7}=\frac{21}{35}[/tex]
[tex]\frac{25}{35}+\frac{21}{35}=\frac{25+21}{35}[/tex]
[tex]=\frac{46}{35}[/tex]
change the improper fraction into mixed number
[tex]6+1\frac{11}{35}[/tex]
[tex]=7\frac{11}{35}[/tex]

Albert Works at a farmers market. he recently sold 18 pieces of fruit, 6 or witch were oranges. what is the experimental probability that the nest piece of fruit Albert sells will be an orange?
Answer: [tex]\dfrac{1}{3}[/tex].
Step-by-step explanation:
Experimental probability = [tex]\dfrac{favorable\ outcomes}{Total\ outcomes}[/tex]
Given: Total pieces of fruit = 18 (Total outcomes)
Number of oranges = 6 (Favorable )
Then, the experimental probability that the nest piece of fruit Albert sells will be an orange = [tex]\dfrac{6}{18}[/tex] [By formula of experimental probability]
[tex]=\dfrac{1}{3}[/tex]
Hence, the required probability is [tex]\dfrac{1}{3}[/tex].

-4w=24 w= i really need the answer
Answer:
-4w = 24 then
w = -6
Step-by-step explanation:
Answer:
w = -6
Step-by-step explanation:
Solve for w:
-4 w = 24
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of -4 w = 24 by -4:
(-4 w)/(-4) = 24/(-4)
Hint: | Any nonzero number divided by itself is one.
(-4)/(-4) = 1:
w = 24/(-4)
Hint: | Reduce 24/(-4) to lowest terms. Start by finding the GCD of 24 and -4.
The gcd of 24 and -4 is 4, so 24/(-4) = (4×6)/(4 (-1)) = 4/4×6/(-1) = 6/(-1):
w = 6/(-1)
Hint: | Simplify the sign of 6/(-1).
Multiply numerator and denominator of 6/(-1) by -1:
Answer: w = -6

y varies inversely with x, y=12 when x=7. Find y when x =10. Picture attached, 15 points and I'll give Brainliest! Due in two hours.
Answer:
y=8.4
Step-by-step explanation:
inverse proportion means y=k/x
k is the constant
y=12, x=7
k=xy ⇒7*12=84
y=84/x
y=84/10
y=8.4
As y varies inversely with x the value of y is 42/5 when x is 10.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, y varies inversely with x.
∴ y = k/x.
12 = k/7.
k = 84.
Now, x = 10.
∴ y = 84/10.
y = 42/5.

many weeks will he have saved $500?
Step 1: Underline any key information
Step 2: Define your variable.
Step 3: Write an equation
Step 4: Solve the equation:
Step 5: Answer in a complete sentence
Answer:
He took 30 weeks to save $ 500
Step-by-step explanation:
Let 'x' be the number of weeks
Money deposited after each week = $ 15
Money deposited 'x' weeks = 15 * x = 15x
Opening balance in his account = $50
So, money that will be in his account after x weeks = 50 +15x
Total money in the bank = $500
50 + 15x = 500
15 x = 500 - 50 { Subtract 50 from both sides}
15x = 450 { Divide both sides by 15}
15x/15 = 450/15
x = 30 weeks
