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]
1. Diego runs a 10 kilometer race and keeps track of his speed. What was diegos speed at the kilometer mark in the race?
Answer: 10 km/ hr
Step-by-step explanation:
In the graph below, Diego's speed at various points during his 10 kilometer race is shown on the y axis while the distance is shown on the x axis.
Looking at the 1km mark on the x axis, Diego's speed on the y-axis is at 10km/ hr and this was the speed he started the race with. After the kilometer mark however, his speed changed and went on to increase to 11km/ hr by the second kilometer mark.

Halen wrote the product 0.4 for the problem at the right. Don says that is not correct because when you multiply tenths by tenths, the product will be in the hundredths. Is Don right? Explain.
Answer:
Helen is correct and Don is wrong
Step-by-step explanation:
Halen wrote the prodect 0.4 for the problem .5×.8. Don says that is not correct since when you multiply tenths by tenths the product will be in the hundreths. Is Don right?
.5 × .8 = 0.4
Helen is correct
Don is wrong because the zero(0) at the end of decimals are usually ignored
Such as: 0.10 ; it is usually written as 0.1
Same thing goes for 0.40 which is written as 0.4
Therefore, Helen is correct and Don is wrong
Find the x-value using substitution.
y = -3x + 11
5x + y = 21
Answer:
5x+(-3x+11)=21
2x+11=21
2x=21-11
2x=10 2x/2=10/2
x=5
Answer:
X = 5
Step-by-step explanation:
here's your solution
=> y= -3x + 11.
=> given equation = 5x + y = 21
=> by putting value of Y in given equation
=> 5x -3x + 11 = 21
=> 2x + 11 = 21
=> 2x = 21-10
=> x = 10/2
=> x = 5

find the value (s) of the variables (s) in each parallelogram.
Step-by-step explanation:
As we can see it is a parallelogram so here the diagonals bisect so
6y + 1 = 4y + 9
6y - 4y = 9 - 1
2y = 8
y = 8 / 2
y = 4
2x - 5 =x + 7
2x + x = 7 + 5
3x = 12
x = 12 / 3
x = 4

find the area of the shaded region
(the number is 8 for anyone not able to read it)
Answer:
≈ 18.3 m²
Step-by-step explanation:
The shaded area (A) is calculated as
A = area of sector - area of right triangle
area of sector = area of circle × fraction of circle
A = πr² × [tex]\frac{90}{360}[/tex]
= π × 8² × [tex]\frac{1}{4}[/tex] = 64π × [tex]\frac{1}{4}[/tex] = 16π m²
area of triangle = [tex]\frac{1}{2}[/tex] × 8 × 8 = 4 × 8 = 32 m²
shaded area is then
A = 16π - 32 ≈ 18.3 m² ( to the nearest tenth )

Rewrite the polynomial in the form ax^2+bx+cax 2 +bx+c and then identify the values of a,a, b,b, and cc. -x+5x^2+1
Given:
The polynomial is
[tex]-x+5x^2+1[/tex]
To find:
The polynomial in the form [tex]ax^2+bx+c[/tex] and find the values of a, b and c.
Solution:
We have,
[tex]-x+5x^2+1[/tex]
Arranging the terms in descending order of their degrees, we get
[tex]=5x^2-x+1[/tex]
[tex]=(5)x^2+(-1)x+1[/tex]
On comparing this polynomial with [tex]ax^2+bx+c[/tex], we get
[tex]a=5,b=-1,c=1[/tex]
Therefore, the value of a is 5, the value of b is -1 and the value of c is 1.

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.
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! :)

You can choose to figure the period out by looking at the distanse between each endpoint on the x-axis, or by using the formula put in plase. Just simply plug the B-term into the formula to get the period. Now, ALL tangent, secant, cosecant, and cotangent functions have NO amplitudes, so you figure out what you want to put in the blank, but make sure it is not a numerical value.

Arthur is organising his collection of dvds he has 135 altogether. The ratio of comedy films to action horror is 6 : 8 : 1
Answer: See explanation
Step-by-step explanation:
The number of comedy films will be:
= 6/(6+8+1) × 135
= 6/15 × 135
= 54 comedy films
The number of action films will be:
= 8/(6+8+1) × 135
= 8/15 × 135
= 72 action films
The number of horror films will be:
= 1/(6+8+1) × 135
= 1/15 × 135
= 9 horror films
A triangle has sides with lengths of 7 meters, 10 meters and 13 meters is it a right triangle
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.

Step-by-step explanation:
First we can calculate the rectangle which would be
6*11=66
then we can calculate the triangle
we know that the base is 6, so if we cut it in half we get two triangles which could get put back together in another rectangle so we would just need to do
6*3=18
then add them together
66+18=84

Please solve quickly 11-14
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.

9514 1404 393
Answer:
a) $15,779.70
b) $13,679.70
c) $210.92
Step-by-step explanation:
a) When tax is added, the total cost is ...
total = price × (1 +tax rate)
total = $14,775 × 1.068 = $15,779.70
__
b) The amount financed is the difference between the total cost and the down payment.
financed = total - down35
financed = $15,779.70 -2100 = $13,679.70
__
c) The monthly payment is found using the amortization formula. It can also be found using any of a number of financial calculators, spreadsheets, or apps.
A = P(r/12)/(1 -(1 +r/12)^-n) . . . . annual rate r, n monthly payments, principal P
A = $13,679.70(0.035/12)/(1 -(1 +0.035/12)^-72) ≈ $210.92
