Answer:
t = 1
Step-by-step explanation:
When you cross multiply the equation becomes:
10(t+8)=10(9)
Now, solve for t.
10(t-8) = 10(9)
10t+80= 90
-80 -80
10t÷10 = 10÷10
t = 1
A snow cone Machine priced at $139 is on sale for 20% off the sales tax rate is 6.75% what is the price of the snowcone machine after the discount and sales tax?

80+ 6.75 = 86.75
139/100 X 86.75 = 120.5825
$120.58
Use the second derivative test to find the relative extrema for f(x)=x^4-2x^2 + 3
If f(x) = x ⁴ - 2x ² + 3, compute the first and second derivatives:
f'(x) = 4x ³ - 4x
f''(x) = 12x ² - 4
Solve f'(x) = 0 to get the critical points of f(x) :
4x ³ - 4x = 4x (x ² - 1) = 0
→ x = -1, x = 0, x = 1
Check the sign of the second derivative at each of these points:
f'' (-1) = 8 > 0
f'' (0) = -4 < 0
f'' (1) = 8 > 0
These indicate the presence of
• two minima of f (-1) = 2 and f (1) = 2
• one maximum of f (0) = 3
which makes C the correct answer.

Step-by-step explanation:
Five plus 6 times a number is equal to 21 minus 2 times the number
Your equation is this:
5+6x=21-2x
Subtract 6x from both sides
5+6x-6x=21-2x-6x
5=21-8x
subtract 21 on both sides
5-21=21-21-8x
-16=-8x Divide -8 on both sides
2=x

Which vectors represent the reflection of the vector across the x-axis?
Answer:
<3, 7> and [3 7], b and c
Step-by-step explanation:
multiply the vector by the matrix {1 0} (top row) {0 -1} bottom row. So you flip the sign of the -7 and this gives us +7.

The recommended amount of vitamin c for young adults is 75 milligrams. You drank a new sports drink that has 165 mg of vitamin C. What precent of the daily amount of vitamin C did you drink??
Answer
not sure
Step-by-step explanation:
Answer: 220%
Step-by-step explanation:
165 of 75 can be written as:
165 /75
To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100
165 /75 × 100 /100 = ( 165 × 100 /75 ) × 1 /100 = 220 /100
Therefore, the answer is 220%

Explain how to get the variable alone in the equation. 3x = 24
Answer:
to get rid of the 3 on the x you have to divide it by 3. whatever you do to one side you have to do to the other side so the answer would be x=8
Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
To get the variable alone you would divide both sides by 3. You do this because 3 is a common factor that both 3 and 24 have. Once you divide 3 on each side, you have x = 8 as your final answer.

Katrina is going to order sweatshirts for her girls mentoring group. The sweatshirts will have the group logo printed on the front. Katrina asks two local companies to give her a price.
• MH Designs will charge $21.50 for each of the sweatshirts.
• Print Rich will charge $18 for each sweatshirt plus a one-time setup cost of $70.
Justify how to determine the number of sweatshirts Katrina would need to order from
each company for the costs to be the same.
Answer:
Katrina would need to buy 20 sweatshirts.
Step-by-step explanation:
The number of sweatshirts Katrina would need to order from each company can be determined by forming the linear equation in two variables.
Given :
Katrina is going to order sweatshirts for her girl's mentoring group.Katrina asks two local companies to give her a price.MH Designs will charge $21.50 for each of the sweatshirts. Print Rich will charge $18 for each sweatshirt plus a one-time setup cost of $70.Let the number of sweatshirts orders from company MH Designs be 'x' and the number of sweatshirts orders from company Print Rich be 'y'.
So, the cost for ordering the sweatshirt from the company MH Design is:
[tex]21.50x = c[/tex]
Now, the cost for ordering the sweatshirt from the company Print Rich is:
18y + 70 = c'
Given that the number of sweatshirts Katrina would need to order from each company for the costs to be the same. So :
21.5x = 18y + 70
Now, put the value of x and y so, that in the above equation, both sides become equal.

The football team has a total of 50jerseys. There are 35 medium sized jerseys. What percent of the jerseys are medium sized jerseys?
Answer: 70%
Step-by-step explanation:
Total number of jersey = 50.
Total number of medium sized jersey = 35
The percent of the jerseys that are medium sized jerseys will be:
= Number of medium sized / Total number of jersey × 100
= 35 / 50 × 100
= 70%
