Answer:
y=6x-14
Step-by-step explanation:
m=-8-(-2)/1-2
m=-8+2/1-2
m=-6/-1
m=6
y-y1=m(x-x1)
y-(-2)=6(x-2)
y+2=6x-12
y=6x-2-12
y=6x-14

Answer:
a) 0
b) -5
Step-by-step explanation:
We want to find f(x) = -4
This means find the value of x where y=-4
The value of x where y=-4 is x=0
Then find f(2)
This means find the value of y when x =2
The value of y when x=2 is -5

3x+(5)(2)+(5)(x)=4x+−7(Distribute)
3x+10+5x=4x+−7

8x+10=4x−7
Step 2: Subtract 4x from both sides.
8x+10−4x=4x−7−4x
4x+10=−7
Step 3: Subtract 10 from both sides.
4x+10−10=−7−10
4x=−17
Step 4: Divide both sides by 4.

Triangle EFG is dilated by a scale factor of one half centered at (1, 1) to create triangle E'F'G'. Which statement is true about the dilation?
Answer:
A triangle is dilated by scale factor of 1/5
Step-by-step explanation:
A triangle has three sides. All the corresponding angles of triangle must be congruent. When the triangle is dilated it is rotated 90 degrees clockwise about its origin. The shape of the triangle will not change due to rotation of dilation.
Which factors of −14 are used to factor x2+5x−14?
Answer:
+ 7 and - 2
Step-by-step explanation:
Given
x² + 5x - 14
Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (+ 5)
The factors are + 7 and - 2 , since
7 × - 2 = - 14 and 7 - 2 = + 5 , then
x² + 5x - 14 = (x + 7)(x - 2) ← in factored form

A school pays $1,825 for 150 shirts. This includes the $25 flat-rate shipping cost.
a. What equation models the total cost as a function of the number of T-shirts
ordered?
b. What does each variable represent?
c. What are the initial value and rate of change of the function? What does each
one represent?
Answer:
a)
We know that the total cost for the 150 shirts (plus a flat-rate of $25) is $1,825.
First, let's find how much costs each shirt.
First, the total cost of the shirts alone (neglecting the flat-rate) is:
$1,825 - $25 = $1,800
Then each shirt costs equal to the quotient of the cost and the number of shirts:
$1,800/150 = $12
Each shirt costs $12.
Then if you order T shirts, the total cost will be the flat-rate of $25 plus T times $12. The equation is:
C(T) = $25 + T*$12
b) C represents the cost
T represents the number of shirts ordered.
c) The initial value is the constant value, in this case, is $25
The rate of change is the coefficient that multiplies the independent variable (T), in the equation the rate of change is $12.

DUS is a 30°-60°-90° triangle with short leg SU. If SU = x, determine the
length of the long leg and the length of the hypotenuse.
Answer:
SD = 2x
UD = x[tex]\sqrt{3}[/tex]
Step-by-step explanation:
The hypotenuse of a 30-60-90 triangle is 2 times the length of the shorter leg.
SU is the shorter leg = x
So, SD = 2x
The longer leg of a 30-60-90 triangle is [tex]\sqrt{3}[/tex] times the shorter leg.
So, UD = x[tex]\sqrt{3}[/tex]
Answer:
Below in bold.
Step-by-step explanation:
In a 30-60-90 triangle the sides are in the ratio 1:√3:2 so if the shortest side SU = x then the long leg = √3x and the hypotenuse = 2x.
Mancuso wants to draw a sector whose area is 2 times the area of the sector shown
Which method will NOT work?
Answer:
Multiply the radius, r, by 2. Keep the angle measure x.
Step-by-step explanation:
The area of the sector whose area is double as that of given sector is : A{new} = {x/90} × πr².
What is function?A function is a relation between a dependent and independent variable.
Mathematically, we can write → y = f(x) = ax + b.
Given is that Mancuso wants to draw a sector whose area is 2 times the area of the sector shown.
The area of the sector given is -
A = {x/180} x πr²
For the area to be double, we can write the area of the sector as -
A{new} = 2 × {x/180} × πr²
A{new} = {x/90} × πr²
Therefore, the area of the sector whose area is double as that of given sector is : A{new} = {x/90} × πr².

Simplify: (-7x - 5) - (-9x2 + 8x + 7). Choose the standard form of the answer.
Answer:
-15x - 12 + 9x^2
Step-by-step explanation:
(-7x - 5) - (-9x^2 + 8x + 7)
-7x - 5 + 9x^2 - 8x -7
-15x - 12 +9x^2
what is that 2 by the 9x
We will simplify the given expression to get:
9x^2 - 15x - 12
How to simplify the given expression?
Here we have the expression:
(-7x - 5) - (-9x^2 + 8x + 7)
To simplify it, we just perform the difference between the polynomials:
-7x - 5 + 9x^2 - 8x - 7
Now we group terms with correspondent powers of x:
9x^2 + (-7x - 8x) + (-5 - 7)
Now we simplify this:
9x^2 - 15x - 12
This is the quadratic equation simplified.

A clothing store conducts a survey to determine customer satisfaction.
Which of these methods will produce the most representative sample of the population of store customers?
A. Survey all customers as they arrive at the store on a Monday.
B. Survey all customers who purchase shoes
C. Survey every 10th customer to enter the store.
D. Survey all customers who leave the store without making a purchase
Answer:
C
Step-by-step explanation:
This method is the best because it will survey the customers under one condition : every 10. If the store gets a lot of customers, then this should be easier to do. The rest are mostly dependent on what they do and that influences the survey. However, C makes it so that every 10 people are surveyed.
Answer:
A isnt the correct answer. B doesnt seem reasonable because its one specific item. D means they arent exactly a customer since they didnt buy anything therefore the answer would be C
C is your answer.

Samantha drives 95 miles each day. How many miles does she drive in 40 days?
Answer:
Samantha drives 3,800 miles in 40 days.

1 day = 95 miles so 40 days = 3,800
95 miles x 40 days = 3,800 miles
Karen and Ricardo are 279 miles apart driving towards each on the same route. Karen drives at a speed of 59 miles per hour and Ricardo drives at a speed of 65 miles per hour. In how many hours will they meet?
Answer:
They will meet in 2.25 hours or 2 hours 15 minutes
Step-by-step explanation:
At any point in time;
distance = speed * time
Let the number of hours at which they meet be x
In x hours, the distance traveled by Karen will be 59 * x = 59x miles
In same x hours, the distance traveled by Ricardo will be 65 * x = 65x miles
Since they are traveling in opposite directions, the distance traveled at that time by Karen will be less than what Ricardo has traveled since he is traveling at a greater speed
However, the sum of whatever they have traveled will be equal to the distance between them
thus;
59x + 65x = 279
124x = 279
x = 279/124
x = 2.25 hours
