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 - 1solve with subsitution
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
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

Step-by-step explanation:
Answer:
y > 2
Step-by-step explanation:
Given
14y - 14 > 14 ( add 14 to both sides )

y > 2
John leaves his home. He travels 5 blocks south and three blocks west. As the crow flies, how far is John from his home?
Answer:
5.83 blocks away from his home
Step-by-step explanation:
If he travels 5 blocks south and 3 blocks west, the distance from his house considered along with the distances travelled gives a right angled triangle whose opposite side and adjacent sides are the distances travelled north and west.
The distance from his house after moving 3 blocks west is the hypotenuse side. As such, the distance may be computed using Pythagoras' theorem. Let the distance from his house be G
G^2 = 5^2 + 3^2
G^2 = 25 + 9
= 34
G = √34
=5.83
John is 5.83 blocks away from his home

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

teri ran 4 kilometers . one mile is approximately equal to 1.6 kilometers. how many miles did teri run
Answer:
2.5 Miles
Step-by-step explanation:
4 k = ? Mile
1.6 k = 1 mi
4/1.6 is 2.5
1x2.5 equals 2.5
so 4 km should be 2.5 mi
4 k = 2.5 Mile
(x2.5)1.6 k = (x2.5)1 mi

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

What is the value of p?
the answer is p=6
hope that helped loll
Answer: 6
Step-by-step explanation:
In a triangle, all three angles always add to 180°.
Thus, simply do 180 - 96 - 54 to get the angle, 30. Then, because the angle is 5p, divide 30/5 = 6.
Hope it helps <3 :D
[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
HOW MUCH WRAPPING PAPER DO YOU NEED TO COVER THE
ENTIRE BOX WITHOUT WASTING ANY PAPER?
Answer:
290 inches
Step-by-step explanation:
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.
