Answer:
2
Step-by-step explanation:
1. Substitute c with -6... so the equation would be -6^2 + 7(-6) + 8
2. Simplify... so -6^2 is 36 because when you square something you times it by itself and two negatives multiplied together equals a positive so -6*-6=36 then 7*-6 is -42 because a positive multiplied by a negative is always a negative
3. So now you have 36 + -42 + 8 or 36 - 42 +8 because an when adding a negative it’s basically just like subtracting because they cancel out
4. So when you simplify it’s simply it’s simply 2 because 36-42 is -6 added by 8 is 2
Sorry if this was confusing I’m really bad at explain gm but hope this helps :)
Hey there!
c^2 + 7c + 8
= -6^2 + 7(-6) + 8
= -36 - 42 + 8
= -78 + 8
= -70
Therefore, your answer is: -70
Good luck on your assignment & enjoy your day!

Larry says 5 × 900 is less than 5 × 9,000. Doni says 5 × 900 is greater than 5 × 9,000. Which statements about the two products are correct? Choose all that apply.
Answer:
Larry's statement is correct
Step-by-step explanation:
Larry says 5 × 900 is less than 5 × 9,000.
Doni says 5 × 900 is greater than 5 × 9,000.
5 × 900 = 4500
5 × 9000 = 45,000
45,000 is greater than 4500 because the place value of 45,000 is tens thousands and 4500 is Thousands.
Hence, Larry's statement is correct.(Larry says 5 × 900 is less than 5 × 9,000.)

If ZMK APY, m M = 112 ° , m Y = 41 ° , m K = (13x 37) ° , and m A = (2y + 7) ° , find the values of x and y.
need a answer asap
Answer
13x-37=112
13x =149
X=11.4
2y+7=41
Y=24
The value of x and y respectively will be 13° and 17°.
Based on the equation that's given in the question, the value of x will be found thus:
13x - 37 = 112
Collect like terms
13x = 112 + 37
13x = 149
x = 149/13
x = 13
Also, note that 2y + 7 = 41, therefore, the value of y will be:
2y = 41 - 7
2y = 34
y = 34/2 = 17°
Therefore, the value of x and y respectively will be 13° and 17°.

4(2x - 1) = 3x + 6 Solve for x. Show steps with sentences supporting each step.
Answer:
x = 2
Step-by-step explanation:
4(2x - 1) = 3x + 6
Simplify
8x - 4 = 3x + 6
Subtract 3x from both sides
8x - 3x - 4 = 3x - 3x + 6
5x - 4 = 6
Add 4 to both sides
5x - 4 + 4 = 6 + 4
5x = 10
Divide both sides by 5
5x/5 = 10/5
x = 2
Step-by-step explanation:
4(2x - 1) = 3x + 6
8x-4=3x+6
8x-3x=6+4
5x=10
x=10/5=2

Ronald said that (8.0 × 107) + (6.2 × 103) = 14.2 x 1010. Amy added the numbers too and said the sum was 8.00062 × 107. Ronald then added the numbers a second time and came up with his original result. Whose solution is correct? Ronald is correct because 80,000,000 + 6,200 = 142,000,000,000.
Yes No B
Amy is correct because adding the decimals and then adding the exponents is not the correct procedure for adding numbers in scientific notation.
Yes No C
Amy is correct because 6.2 × 103 is a much smaller number than 8.0 × 107, so the sum of the two numbers cannot be as large as a decimal times 1010.
Yes No D
Ronald is correct because when you add the exponents in 107 and 103, you get 1010.

Which graph represents the polynomial function h(x) = x3 + 2x2 – 11x – 12?
y
Answer:
I attached a pic of the answer. I just did the quiz. Hope this helps!!!
Step-by-step explanation:
The graph of the polynomial function h(x) = x³ + 2x² - 11x -12 has been shown.
Given that,
To determine the graph of the polynomial function h(x) = x³ + 2x² - 11x -12.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
The graph of the function h(x) = x³ + 2x² - 11x -12 can be drawn as the function is a polynomial of degree 3 so it will follow two ups and down,
So the graph can be drawn as shown in the image.
Thus, the graph of the polynomial function h(x) = x³ + 2x² - 11x -12 has been shown.

The store sells gasoline for .25 per gallon below it's regular cost per gallon .Suppose the store sells 5,750 gallons that day .What is the stores profit or loss in comparison to the amount the store would had made without the special
Given :
The store sells gasoline for .25 per gallon below it's regular cost per gallon.
Suppose the store sells 5,750 gallons that day.
To Find :
the stores profit or loss in comparison to the amount the store would had made without the special offer.
Solution :
Since, store is selling gasoline for lower amount than regular so they will be in loss.
Loss =$ 0.25 × 5750
Loss = $1437.5
Therefore, loss of store in comparison to the amount the store would had made without the special offer is $1437.5 .
Hence, this is the required solution.

express 20cm as a percentage of 3m.
give your answer as a mixed number
Answer:
[tex]6\frac{2}{3}[/tex] %
Step-by-step explanation:
First, convert 3 meters into centimeters.
1m = 100cm
3m = 100 × 3 = 300cm
Now, form the fraction by putting the given value, 20cm, over the total measurement, 300cm.
[tex]\frac{20}{300}[/tex] = [tex]\frac{2}{30}[/tex] = [tex]\frac{1}{15}[/tex] ⇒ Simplify your fraction to its simplest terms.
Next, multiply your simplified fraction by 100 to get your percentage.
[tex]\frac{1}{15}[/tex] × [tex]100[/tex] = [tex]\frac{100}{15}[/tex] = [tex]6\frac{10}{15}[/tex] = [tex]6\frac{2}{3}[/tex] % ⇒ Simplify your percentage to its simplest terms.

Step-by-step explanation:
J=28
Answer:

Gabriel invested $77,000 in an account paying an interest rate of 3 1/2% compounded monthly. Isabella invested $77,000 in an account paying an interest rate of 4 1/8% compounded quarterly. After 6 years, how much more money would Isabella have in her account than Gabriel, to the nearest dollar?
WE know, compound interest is given by :
[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
Here, P is principle amount.
r is annual interest rate.
n, number of times that interest is compounded per unit t .
t, time the money is invested or borrowed for.
To Find :
How much more money would Isabella have in her account than Gabriel, to the nearest dollar.
Solution :
[tex]D = P(1 + \frac{r_1}{n})^{nt}- P(1 + \frac{r_2}{n})^{nt}\\\\D = 77000\times ( 1 + \dfrac{33}{8\times 12})^{12\times 6}-77000\times ( 1 + \dfrac{7}{2\times 12})^{12\times 6}\\\\D = \$(1.257\times 10^{14})[/tex]
Hence, this is the required solution.

A cellphone store has 120 cell phones in stock. Of these, 45 have keyboards. The manager of the store wants to add more cell phones with keyboards so that 40% of the stock has keyboards.
Answer:
5
Step-by-step explanation:
Let x be the number of cell phones with keyboards needed.
40% = [tex]\frac{40}{100}[/tex]
[tex]\frac{x+45}{x+120}[/tex] = [tex]\frac{40}{100}[/tex]
x+45 = 40 -----1
x+120 = 100 -----2
You would want to make the total of 1 the same as 2.
1×[tex]\frac{100}{40}[/tex]: 2.5+112.5 = 100 -----3
Now 2 and 3 are equal.
x+120 = 2.5x+112.5
Isolate the x and numbers.
120-112.5 = 2.5x-x
Simplify.
1.5x = 7.5
x = [tex]\frac{1}{1.5}[/tex] × 7.5
x = 5
The manager of the store needs to add 5 more cell phones with keyboards.
