Answer:
we can verify that the determined equation is the same as the equation determines by Misty, hence, we conclude that Misty had correctly determined the equation of the linear function.
Step-by-step explanation:
As Misty determined the equation of linear function:
[tex]y=-2x+9[/tex]
We need to check whether she has got the correct equation or not.
As the linear equation passes through the points [tex](1, 7)[/tex] and [tex](2, 5)[/tex].
Finding the slope:
The slope between two points [tex](1, 7)[/tex] and [tex](2, 5)[/tex]
[tex]\left(x_1,\:y_1\right)=\left(1,\:7\right),\:\left(x_2,\:y_2\right)=\left(2,\:5\right)[/tex]
[tex]m=\frac{5-7}{2-1}[/tex]
[tex]m=-2[/tex]
As we know the point-slope form is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
So, the equation of the line will be:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-5=-2\left(x-2\right)[/tex]
Add 5 to both sides
[tex]y-5+5=-2\left(x-2\right)+5[/tex]
[tex]y=-2x+9[/tex]
From the above calculation, we can verify that the determined equation is the same as the equation determines by Misty, hence, we conclude that Misty had correctly determined the equation of the linear function.

Which of the following inequalities has a solution x≥−3
3(x−1)≤4x
x≥x+32
x6≤x2−1
x+4≥x3
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:-
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 complete solution is given below:-
3(x-1) ≤ 4x
3x - 3 ≤ 4x
-3 ≤ 4x - 3x
-3 ≤ x
x ≥ -3
Therefore, the inequality 3(x−1)≤4x is showing the solution x ≥−3. The correct option is A.

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

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°.

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.

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.

Write an equation to represent the following statement. j is 25 more than 3 Solve for j
Answer:
j=3+25, here's the equation
Step-by-step explanation:
J=28
Answer:
j = 28
Step-by-step explanation:
Since we know that j is 25 more than 3, then we must know that 3+25= J (because J is 25 more/+ than 3) So, we simply solve 25+3 which equals 28.

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.
