Answer:
x -22
Step-by-step explanation:
Sum = -7 (-22+15 = -7)
Product = -330 (-22*15 = -330)
Factors = -22 , 15
x² - 7x - 330 = x² +15x - 22x - 22 *15
= x(x + 15) -22(x + 15)
= (x +15)(x -22)
[tex]\frac{x^{2}-7x-330}{x + 15}=\frac{(x+15)(x-22)}{(x+15)}\\\\ =x - 22[/tex]

Slope is (the change in y) / (the change in x).
The formula for slope is:
m = (y2 - y1)/(x2 - x1), with (x1, y1) being one point and (x2, y2) being the second. What you need to do is order the slopes from smallest to largest because slope means the same thing as rate of change.
#17. First, you need to find the slope of function A. To do this, I’m choosing two different points I see on the graph: (1,1) and (2,1). I now plug these into the slope formula:
m = (1-1)/(2-1) = 0/1 = 0.
The slope for function A = 0
To find the slope for function B, you can choose any two points. I’m going to use (3,0) and (6,1)
m = (1-0)/(6-3) = 1/3
The slope for function B is 1/3
For function C, you are already given the slope. That equation is in something called slope-intercept form (y=mx+b), where the x is being multiplied by the slope.
The slope on function C = 1/4
So,, A has the smallest slope, C has the second smallest slope, and B has the largest slope.
#18. The two points in using to find the slope for function A are (0,-3) and (1,0).
m = (0+3)/(1-0) = 3/1 =3
The slope for function A is 3
The two points I’m using for function B are (-2, 10) and (0, 20)
m = (20-10)/(0+2) = 10/2 = 5
The slope for function B is 5
The slope for function C is 1. When the slope is 1, it is not written because any number (other than 0) times 1 equals 1.
Function C has the smallest slope, function B has the second smallest slope, and function C had the largest slope.

The speed of the current in a river 6 mph. A very operator who works top part of the river is looking to buy a new boat for his business. Every day, his route takes him 22.5 miles each way against the current back back to the dock, and he needs to make his trip any tour of nine hours. He has a bow in mind, but he can only test it on a leak where there is no current. How fast must the boat go on the lake in order for it to serve the ferry operators needs?
Answers
Answer:
9 mph
Step-by-step explanation:
Speed of current = 6 mph
Distance to travel one way = 22.5 miles
Let speed of the ferry be [tex]x[/tex] mph
Total time taken for round trip is 9 hours
One way the ferry will be going with the current and in the other way the ferry will be going against the current so
[tex]\dfrac{22.5}{x+6}+\dfrac{22.5}{x-6}=9\\\Rightarrow \dfrac{x-6+x+6}{x^2-36}=\dfrac{9}{22.5}\\\Rightarrow \dfrac{2x}{x^2-36}=0.4\\\Rightarrow \dfrac{2x}{x^2-36}-0.4=0\\\Rightarrow 2x-0.4x^2+14.4=0\\\Rightarrow 0.4x^2-2x-14.4=0\\\Rightarrow 4x^2-20x-144=0\\\Rightarrow x=\dfrac{-\left(-20\right)\pm \sqrt{\left(-20\right)^2-4\times 4\left(-144\right)}}{2\times 4}\\\Rightarrow x=9,-4[/tex]
So, the speed of the boat in still water needs to be 9 mph both ways.

Henry and his children went into a grocery store and where they sell peaches for $2 each and mangos for $1.25 each. Henry has $20 to spend and must buy no less than 10 peaches and mangos altogether. If Henry decided to buy 4 peaches, determine all possible values for the number of mangos that he could buy. Your answer should be a comma separated list of values. If there are no possible solutions, submit an empty answer.
Answers
Since 4 peaches x 2 =8, you would would only be able to buy 6 mangos since $1.25 x 6 mangos =$7.5 so it would be $7.5+$8=$15.5 and 6 mangos+4 peaches=10 in total. And he would also save $5.00! :)

Don is wrong because the zero(0) at the end of decimals are usually ignored

Answers
Answer:
Step-by-step explanation:
11). 6x + 3y = 9
3(2x + y) = 9
2x + y = 3
y = -2x + 3
Since variables are of single degree therefore, it's a linear function
12). 3y - 2x = -2x - 12
3y - 2x + 2x = -2x - 12 + 2x
3y = -12
y = -4
Since variable y is of single degree therefore its a linear function.
13). 11y + 4x = -8 + 11y
11y + 4x - 11y = -8 + 11y - 11y
4x = -8
x = -2
Linear function.
14). 4x - 3 + 2y = 8x - 9
4x + 2y - 3 - 4x = 8x - 4x - 9
2y - 3 = 4x - 9
2y = 4x - 9 + 3
2y = 4x - 6
y = 2x - 3
Linear function.
A triangle has sides with lengths of 7 meters, 10 meters and 13 meters is it a right triangle
Answers
Answer:
No
Step-by-step explanation:
7 squared + 10 squared = 149
13 squared = 169
As you can see these two products are not equal. They have to be equal to be a right triangle.
So this triangle is not a right triangle.
Hope that helped you and have a great day!
Answer:
No it is not.
Step-by-step explanation:
Let h = 13, p = 10 and b =7
Using pythagoras theorem,
h² = p² + b²
13² = 10² + 7²
169 = 100 + 49
169 = 149
This is false so the triangle is not a right angled triangle.
