Answer:
A. {1, 7, 11}
Step-by-step explanation:
The constant in the equation is 1, so that is the value when x=0. No answer choice can be correct unless it includes the value 1. The only viable choice is A.
_____
If you want to go to the trouble to evaluate the expression for the different values of x, you can. It often works well to rewrite the expression to "Horner form":
(2x -1)x +1
For x = -2, this is (2(-2) -1)(-2) +1 = (-5)(-2) +1 = 11
For x = 0, this is 1
For x = 2, this is (2(2) -1)(2) +1 = (3)(2) +1 = 7
So, the range for the given domain is {1, 7, 11} . . . . . matches choice A
Subtract -2x^2+3x-9
from 8x^2+10x-10
Answer:
-6x^2 - 7x +1
Step-by-step explanation:
2x^2+3x-9 -(8x^2+10x-10)
3x^2+3x-9 -8x^2-10x+10
Combine like terms
-6x^2 - 7x +1

Step-by-step explanation:
8x + y = -16
y = -8x - 16 --(1)
-3x + y = -5 --(2)
sub (1) into (2):
-3x - 8x - 16 = -5
-11x = 11
x = -1
sub x = -1 into (1):
y = -8(-1) - 16
y = -8
therefore, the solution is (-1, -8).

Step-by-step explanation:
Joseph makes ornaments to sell at the craft fair. Each ornament requires 0.5 yards of velvet. At the fabric store, felt is sold by the foot. If Joseph wants to make 45 ornaments, how many feet of velvet must be buy? If the felt costs 10 cents ($0.10) per foot, what is the total cost of the velvet in dollars? A manufacture is making 1,000 times as many ornaments as Joseph to sell in stores nationwide. Write an expression using exponents to show how many yards of velvet the manufacture will need. Do not calculate the total.
Answer: See explanation
Step-by-step explanation:
A. Since each ornament requires 0.5 yards of velvet and Joseph wants to make 45 ornaments, the number of yards of velvet she must be buy will be:
= 45 × 0.5
= 22.5 yards
Since 1 yard = 3 feet
22.5 yards = 22.5 × 3 = 67.5 feet
B. If the felt costs 10 cents ($0.10) per foot, what is the total cost of the velvet in dollars.
Total Cost = 67.5 × $0.10 = $6.75
C. A manufacture is making 1,000 times as many ornaments as Joseph to sell in stores nationwide. The amount of yards needed will be:
= 1000(45 × 0.5)
Jessica is hiring a plumber to remodel her bathroom. She knows that this job will take many hours to complete, so she wants to find a plumber that costs less than
$50 per hour (not including the fee for coming out to her house). A number of plumbers submitted the cost of their most recent job. Which of the following
plumbers cost less than $50 per hour? Select two that apply.
O Pattie's Plumbing charged $400 for a 7 hour job. There is no fee to come to the house,
Shannon's Plumbing charged $370 for a 5.5 hour job. This includes an $80 fee to come to the house.
Axel's Plumbing charged $220 for a 4 hour job. This includes a $10 fee to come to the house.
Bill's Plumbing charged $180 for a 2 hour job. This includes a $100 fee to come to the house
Tyrese's Plumbing charged $280 for a 3.5 hour job. This includes a $120 fee to come to the house
OOOO
Answer:
B and E
Step-by-step explanation:
B. You subtract the & $120 from $280, then divide the sum by 3.5 hours you’ll get $45.71
E.you subtract the $100 from $180 and divide it by 2 hours you get $40
Bill's Plumbing charged $180 for a 2-hour job. This includes a $100 fee to come to the house
Tyrese's Plumbing charged $280 for a 3.5-hour job. This includes a $120 fee to come to the house
From the given question, we need to determine the plumber that costs less than $50 per hour.
For the first option, if Pattie's Plumbing charged $400 for a 7-hour job, the cost per hour will be $400/7 = $57.14/hr. This shows that the plumber cost more than $50 per hourFor the second option, If Shannon's Plumbing charged $370 for a 5.5-hour job, the amount she is making in an hour is 370/5.5 = $67.27. This shows that Shannon cost more than $50 per hourIf Bill's Plumbing charged $180 for a 2-hour job and this includes a $100 fee to come to the house, Bill's pay per hour will be (180-110)/2 = $35. This shows that Bill cost less than $50 per hourIf Tyrese's Plumbing charged $280 for a 3.5-hour job and it includes a $120 fee to come to the house. Tyrese's pay per hour will be (280-120)/3.5 = $45.7. This shows that Tyrese cost less than $50 per hour

Is this graph a function or not a function
Answer:
In the graph of a circle, we can easily draw a straight vertical line passing through its center. This will hit the top and the bottom of the shape. Since this line hits two points, a circle's graph is not a function. We can also observe the equation of a circle.
Answer:
No
Step-by-step explanation:
Do a vertical line test.
First, put your pencil or ruler up against the screen.
Move it down the graph and if there are two points in one x point, it is not a function. For example, look at 0, 3 and 0, -2.5. They share the same x point.
Therefore, it is not a function.

Answer: B . y = 5/6x + 7
Step-by-step explanation:
5x - 6y = - 42 To write it in slope intercept form, we need to solve for y.
-5x -5x Subtract 5x from both sides
-6y = -5x - 42 Divide both sides by -6
y = 5/6x + 7

How to find the value
Answer:
x = 4°
Step-by-step explanation:
According to exterior angle sum property , sum of two opposite interior angles of the triangle is equal to the exterior angle.
So, using exterior angle sum property :-
mBDC + mBCD = mWBC
=> 8x - 1 + 46° = 18x + 5
=> 18x - 8x = 46 - 1 - 5
=> 10x = 40
=> x = 4°

Find each numbered angle measure:
Answer:
m∠1=77°
m∠2=36°
m∠3=30°
Step-by-step explanation:
First, find angle 1 by adding 66 and 37 and subtracting them from 180 because there are 180 degrees in an angle.
180-(66+37)=77°
You can then find angle 2 by finding the other angle not given. You can find this angle by subtracting 77 from 180, giving you 103. To find angle 2, add 103 and 41 and subtract them from 180.
180-(103+41)=36°
You can then find angle 3 by adding the angle 103 and the angle 47, and subtracting them from 180
180-(103+47)=30°
