The table shows a relationship between values of x and y.
Which of the following equations describes the relationship for the values in the table?
A.
y = 2x^2 – 1
B.
y = x^2 + 3
C.
y = 2x^2 + 1
D.
y = 10x – 3
Answer:
A. y = 2x^2 - 1Step-by-step explanation:
Try the points of x and y by substitution
This gives us the function:
y = 2x^2 - 1[tex]2x^2-20x=x^{2} -19[/tex]
Answer:
x = 1, x = 19
Step-by-step explanation:
Given
2x² - 20x = x² - 19 ( subtract x² - 19 from both sides )
x² - 20x + 19 = 0 ← in standard form
(x - 1)(x - 19) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x - 19 = 0 ⇒ x = 19
what are the answers to these?!?!?!?>>>>>

Chris works at a jewelry store, and he earns 4% commission on all sales that he makes. If Chris's jewelry sales total $1,370, how much will he earn in commission?
Answer:
[tex]\boxed {\boxed {\sf \$54.80}}[/tex]
Step-by-step explanation:
Chris earns the commission on the jewelery sales. To calculate what he earned, multiply the commission rate and his sales.
[tex]commission= commission \ rate * sales[/tex]
His rate is 4% and his sales are $1,370
[tex]commission= 4\% * \$1370[/tex]
Convert the percent to a decimal. Divide by 100 or move the decimal two spots to the left.
4/100= 0.04 4.0 --> 0.4 --> 0.04[tex]commission= 0.04* $1370[/tex]
[tex]commission = \$ 54.8[/tex]
Chris's commission is $54.80
LLoyd used 1/4 of chocolate to make 2/3 gallons of chocolate pudding. If Lloyd's recipe is for 1 gallon of pudding, how many pounds of chocolate will he need to make 1/3 the recipe?
Answer:
1/8
Step-by-step explanation:
Llyod used 1/4 chocolates to make 2/3 gallons of chocolate pudding
= 1/4 ÷ 2/3
= 1/4 × 3/2
= 3/8
Therefore the number of pounds needed to make 1/3 of the recipe can be calculated as follows.
= 3/8 × 1/3
= 3/24
= 1/8

-4x+y=3 and 2x-y=12. which of the options represents the resulting equation after an equivalent expression for yw is substituted into the second equation. Odessyware!
Answer:
2x - (3 + 4x) = 12
x = -7.5
y = -27
Step-by-step explanation:
-4x + y = 3 (1)
2x - y = 12 (2)
From (1)
y = 3 + 4x
Substitute y = 3 + 4x into (2)
2x - y = 12 (2)
2x - (3 + 4x) = 12
2x - 3 - 4x = 12
2x - 4x = 12 + 3
-2x = 15
x = 15/-2
x = -7.5
Substitute x = -7.5 into (2)
2x - y = 12 (2)
2(-7.5) - y = 12
-15 - y = 12
-y = 12 + 15
- y = 27
y = -27
To pass inspection, a new basketball should bounce back to between 68% and 75% of the starting height. A new ball is dropped from 6 feet and bounces back 4 feet 1 inch. does the ball pass inspection? Explain
To pass inspection, the ball must bounce back to between 68% and 75% of the starting height. written as a decimal, the ball must bounce between a low of __ feet and height of __ feet.
Answer: Yes, it does. It must bounce of a low of 4.08 feet and a high of 4.5 feet

The base of a triangle prism shown is an isosceles triangle having a height of H cm, and an area of 36cm squared
The perimeter of the front rectanglular face of the prism is 54cm
state the value of h on the diagram
Answer:
the value of h on the diagram is 9cm
Step-by-step explanation:
area = 1/2 * base * height
a = 1/2*b*h
36=1/2*8*h
36=4h
since the 1/2 will multiply the 8
36=4h
multiply both sides by 4
h=9cm.
if a/b=2/3, find the value of 3a/4b
Answer:
1/2
Step-by-step explanation:
Given data
from the expression a/b=2/3 we can see that
a= 2
b= 3
given the expression
3a/4b
=3*2/4*3
=6/12
=1/2
Hence the answer is 1/2

y-3x=2
y=-2x-8
show ur work HURRY PLSS
Answer:
y-3x=2......1
y=-2x-8 ......2
substituting value of y in equation 1
-2x-8-3x=2
-5x=2+8
x=10/-5=-2
substituting value of x in equation 1
y-3×(-2)=2
y+6=2
y=2-6=-4
x=-2
y=-4
(
Answer:
(-2, -4) or x = -2 y = -4
Step-by-step explanation:
Solve with subsitution
y-3x=2
y=-2x-8
1. Substitute -2x - 8 in for the y in y - 3x = 2 (-2x - 8) - 3x = 2
2. Solve for x. Combine like terms. -5x - 8 = 2
3. Solve the one step equation. +8 +8
-5x = 10
-5 -5
x = -2
4. Substitute the -2 in for x in either equation. y = -2x - 8
y = -2(-2) - 8
y = 4 - 8
y = -4
Please help me with both of these!!

Write the rule for the arithmetic sequence in slope intercept form: 17,12, 7, 2....
9514 1404 393
Answer:
an = -5n +22
Step-by-step explanation:
We observe that the sequence has 17 as its first term and a common difference of 12-17 = -5. Then the general term is ...
an = a1 +d(n -1)
an = 17 -5(n -1)
This can be simplified to the desired form.
an = 17 -5n +5
an = -5n +22
Billy had 5 gallons of paint. Bob had 4 kilograms of paint. How do you make the paint amount equal?
Answer:
We can make the paint amount equal by making sure the parameters have the same unit
Step-by-step explanation:
Billy had 5 gallons of paint. Bob had 4 kilograms of paint. How do you make the paint amount equal?
To solve the above question, we have the conversion rate:
We can make the paint amount equal by making sure the parameters have the same unit
Hence:
1 gallon (gal) = 3.785411784 kilogram (kg).
Billy had 5 gallons of paint.
1 gallon (gal) = 3.785411784 kilogram (kg).
5 gallons of paint = x
Cross Multiply
x = 5 × 3.785411784 kg
18.92705892 kilograms of paint
Approximately 18.93 Kilograms of paint
Therefore, Billy had 18.93 kg of paint and Bob had 4 kg of paint

A major storm has winds speeds that are at least 110 miles per hour.Write and solve an inequality that describes how much greater these wind speeds are than the slowest hurricane
Answer:
x ≥ 36 miles per hour
Step-by-step explanation:
The speed of a major storm is at least 110 miles per hour while the speed of the slowest hurricane is at least 74 miles per hour.
Let x represent how much greater these wind speeds are than the slowest hurricane. Therefore:
x ≥ 110 miles per hour - 74 miles per hour
x ≥ 36 miles per hour
This means that the winds speed must be 36 miles per hour greater than the slowest hurricane.
