y
Answers
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.

Answer:
y= -2x + 80
Step-by-step explanation:
First, you need to find the slope, which can be done by subtracting the change in y over the change in x. The easiest points to pick are (30,20) and (40,0). Do 20-0 which is -20, then divide that by 40-30, and you get -2. Then to find the y intercept, pick a point (like 40,0). Then do 0 = -2(40) + b, and solving for b you get 80.

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.

need a answer asap
Answers
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°.

express 20cm as a percentage of 3m.
give your answer as a mixed number
Answers
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.

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.
Answers
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.

Which of the following inequalities has a solution x≥−3
3(x−1)≤4x
x≥x+32
x6≤x2−1
x+4≥x3
Answers
Answer: A
Step-by-step explanation: 3(x-1) becomes 3x -3 ≤ 4x. Put all like variables on the same side, meaning you'll subtract 3x from both sides giving you -3 ≤ x. You can flip the equation around to make it look exactly like x ≥ -3
The inequality 3(x−1)≤4x is showing the solution x ≥−3. The correct option is A.
What is inequality?inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
The inequality 3(x-1) ≤ 4x will be solved as below:-
