The first term will be an x because
x squared breaks down as x times x.
First look for factors of your constant that add to your
coefficient of the middle term in the trinomial.
Also note that the constant is negative and a negative
factors as the product of a positive and a negative.
The factors of -20 that add to -8 are -10 and +2.
So we have y = (x - 10)(x + 2).

Step 1: Define
Point (0, 0)
Point (5, -10)
Step 2: Find slope m
Simply plug in the 2 coordinates into the slope formula to find slope m. Slope and gradient is the same.
Substitute in points [SF]: [tex]\displaystyle m=\frac{-10-0}{5-0}[/tex][Fraction] Subtract: [tex]\displaystyle m=\frac{-10}{5}[/tex][Fraction] Divide: [tex]\displaystyle m=-2[/tex]Answer:
Let "m" be the slope of the line passing through the point.
[tex]m = \frac{y_ 2 - y_1}{x_ 2 - x_1 } = \frac{( - 10 - 0)}{(5 - 0)} = \frac{ - 10}{5} = \boxed{- 2 }[/tex]
-2 is the gradient of the line that passes through the points (0,0) and (5,-10).
Shelley delivered 10 newspapers after 20 minutes and 30 newspapers after 60 minutes what is rate of change that represents how many paper shelley's delivering every minute
Answer:
1 newspaper per 2 minutes
Step-by-step explanation:
If you look at 10 newspapers per 20 minutes, you can divide newspapers by minutes which gives you 10/20 = 1 newspaper per 2 minutes. To check the answer, you can do 2*30=60 since 2 minutes per each newspaper would equal 60 minutes.

Step-by-step explanation:
If f(x) = -x + 5 and g(x) = x^2, what is (g° (-1)?
Answer:
[tex](g\circ f)(-1)=36[/tex]
Step-by-step explanation:
We are given the two functions:
[tex]f(x)=-x+5\text{ and } g(x)=x^2[/tex]
And we want to find:
[tex](g\circ f)(-1)[/tex]
This is equivalent to:
[tex]=g(f(-1))[/tex]
So, evaluating f(-1) first, we acquire:
[tex]f(-1)=-(-1)+5=6[/tex]
Then by substitution:
[tex]=g(6)[/tex]
So:
[tex]=(6)^2=36[/tex]
Therefore:
[tex](g\circ f)(-1)=36[/tex]
Your answer is indeed correct.

What is the apparent solution to the system of equations?
y = -2 +2
y=40 +7
Graph the system of equations using the Line tool. Plot a point at the apparent solution to the system using the point tool.
Answer:
y=−x+2y=4x+7 NO
y=−x+2 YES
y=4x+7
Multiply the first equation by 4, obtaining: 4y = -4x + 8
Add the 2nd equation to this result: y = 4x + 7
--------------------
5y = 15, and y = 3
Then, using the first equation, determine x:
y = 3 = -x + 2
1 = -x, so x = -1
The solution is (-1, 3)
Answer: (-1; 3)
Step-by-step explanation:
y = -x + 2
y = 4x + 7
4x + 7 = -x + 2
4x + 7 + x - 7 = - x + 2 + x - 7
5x = - 5
x = - 1
y = 4(-1) + 7
y = 3
Intersection point: (-1; 3)

A beam bridge has a total length of 168 yards. The bridge is supported at both ends and has three additional supports in the water. What is the span between any two consecutive supports?
The answer is 6
Step-by-step explanation:
6-65
The total length of a beam bridge is 168 yards. then the span between any two consecutive supports is 23 approx.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Given that the total length of a beam bridge is 168 yards.
The Total number of supports on the bridge = 1 at both end + 3 additional = (1 + 3 + 1) = 5 supports
Arch lies in between two successive supports ;
Hence, the number of archs = 5
Hence, width of arch = (5 * x) = 5x meters
Width of support = 2 meters
The Total width of support : (2 * x+ 1) = 2(x + 1) meters
Hence, the total distance of bridge :
Total arch width + total support width
5x + 2(x + 1) = 168 meters
5x + 2x + 2 = 168
7x = 166
x = 23 approx
Hence, the span between any two consecutive supports is 23 approx.

Esther and her 6 brothers went shopping at the mall. She shopped in 12 different stores while her brothers each shopped in 8 different stores. How many stores did Esther and her brothers shop in altogether?
Answer:
60 stores
Step-by-step explanation:
Here, we want to get the total number of stores in which Esther and her 6 brothers went shopping
From the question, she shopped in 12 different stores
Each of her six brothers shopped in 8 different stores
That makes the number of stores in which the brothers shop be 8 * 6 = 48 stores
The total number of stores is thus, 48 + 12 = 60 stores
A rectangle made of squares is shown . The length of the side of each square is 1 cm create an equation to find the area of the rectangle. Move numbers an symbols to the lines
Answer:
See Explanation
Step-by-step explanation:
The rectangle is not shown. To solve this question, I'll make use of the attachment.
Apply the same steps, and you'll get the answer to your question.
From the attachment, we have:
[tex]Rows = 3[/tex]
[tex]Columns = 4[/tex]
Since the length of each square is 1 cm, then
[tex]Row = 3cm[/tex]
[tex]Column = 4cm[/tex]
So, the area is:
[tex]Area = Row * Column[/tex]
[tex]Area = 3cm * 4cm[/tex]
[tex]Area = 12cm^2[/tex]
