Answer:
$14Step-by-step explanation:
Step one:
given data
we are told that the discounted price is $7
and the applied discount is 50%
so if 50% of the original price is $7
Step two:
let the original price be x
50/100*x=7
0.5x=7
divide both sides by 0.5
x=7/0.5
x=$14
These means that the original price is $14

What is the slope of the line through (–2. -6) and (2, 2)?
Answer:
slope is 2
Step-by-step explanation:
slove each system of equations using graphing, substitution or elimination. y=2x-3 y=2x+3
y=2x-3
y=2x+3
Since the both expressions 2x-3 and 2x+3 are equal to y, set them equal to each other forming an equation in x.
2x-3=2x+3
Cancel equal terms on both sides of the equation
-3=3
The statement is false for any value of x and y , so there is no solution
Please help me and I’ll give you brainiest make sure to explain :)
Answer:
y = -2/3x -5
Step-by-step explanation:
First, let's fill in our equation of y = mx + b
(6, -9) is the coordinate we will be subsituting
If the equation that s to the one we are solving we must turn its slope into it's negative reciprocal, which would go from 3/2 to -2/3
Now let's substitute and solve
y = mx + b
(-9) = -2/3(6) + b
-9 = -4 +b
+4 +4
-5 = b
Now we create the equation
y = -2/3x -5

Find the measures of the sides of triangle JKL, then classify it by its sides J(-3, 2), K(2,6), L(8, -1)
Given:
The vertices of the triangle JKL are J(-3, 2), K(2,6), L(8, -1).
To find:
The measures of the sides of triangle JKL and classify it by its sides.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using distance formula, we get
[tex]JK=\sqrt{(2-(-3))^2+(6-2)^2}[/tex]
[tex]JK=\sqrt{(2+3)^2+(4)^2}[/tex]
[tex]JK=\sqrt{(5)^2+(4)^2}[/tex]
[tex]JK=\sqrt{25+16}[/tex]
[tex]JK=\sqrt{41}[/tex]
Similarly,
[tex]KL=\sqrt{\left(8-2\right)^2+\left(-1-6\right)^2}=\sqrt{85}[/tex]
[tex]JL=\sqrt{\left(8-\left(-3\right)\right)^2+\left(-1-2\right)^2}=\sqrt{130}[/tex]
Now,
[tex]JK^2+KL^2=(\sqrt{41})^2+(\sqrt{85})^2[/tex]
[tex]JK^2+KL^2=41+85[/tex]
[tex]JK^2+KL^2=126[/tex]
[tex]JK^2+KL^2\neq JL^2[/tex]
Since, measure of all sides are different and sum of squares of two smaller sides is not equal to the square of largest side, therefore the triangle is scalene triangle.
Zoe and Josiah are both selling cookie dough for a fundraiser. Although Zoe has already sold 12 tubs, Josiah hasn't sold any yet. If Zoe starts selling 2 tubs per day and Josiah begins selling 4 tubs per day, they will eventually sell the same amount of cookie dough.
Answer:
6 days
Step-by-step explanation:
Given
Zoe
Sold out = 12
Rate = 2 daily
Josiah
Sold out = 0
Rate = 4 daily
Required
Determine when they sell the same number of tubs
Represent days with d
The number of tubs sold in any give day can be calculated using:
Tubs = Sold out + Rate * Number of days
For Zoe:
Expression: 12 + 2 * d
Expression: 12 + 2d
For Josiah
Expression: 0 + 4 * d
Expression: 4 * d
Expression: 4d
Next, we equate both expressions to get the number of days
4d = 12 + 2d
Collect like terms
4d - 2d = 12
2d = 12
Solve for d
d = 12/2
d = 6
Hence, it'll take 6 days

cos(x+y) + cos(x-y) = 2cosx cosy
Answer:
2cosx cosy = 2cosx cosy
Step-by-step explanation:
cos(x+y) + cos(x-y) = 2cosx cosy
Use the formula for "Functions of the sum of two angles" and the "Function of the Difference of Two Angles" and substitute that in.
(Cosx cosy - sinx siny) + (cosx cosy + sinx siny)
Drop the parentheses
Cosx cosy - sinx siny + cosx cosy + sinx siny
Sinx siny can cancel
Cosx cosy + cosx cosy
This can be simplified to
2cosx cosy

Which of the following is not a polynomial?
Vary the scale factor n from values less than 1 to values greater than 1. How do the points in the resulting images differ from the corresponding points on the preimage? Describe the general location of the points relative to the center of dilation. What happens to the logo of the sailboat as you vary the scale factor?
PLATO
Answer: For values of n < 1, all the points on the image move closer to the center of dilation and the logo shrinks. For values of n > 1, all the points on the image move farther from the center of dilation and the logo expands.
Step-by-step explanation: PLATO sample answer. hope it helps :)
Answer:
For values of n < 1, all the points on the image move closer to the center of dilation and the logo shrinks. For values of n > 1, all the points on the image move farther from the center of dilation and the logo expands.

Veronica works each day and earns more money per hour the longer she works. Write a function to represent a starting pay of $20 with an increase each hour by 5%. Determine the range of the amount Veronica makes each hour if she can only work a total of 8 hours.
20 ≤ f(x) ≤ 28.14
20 ≤ f(x) ≤ 29.55
20 ≤ f(x) ≤ 26.80
20 ≤ f(x) ≤ 25.53
Answer:
f(x) = 20(1.05)^x
Step-by-step explanation:
f(x) = 20(1.05)^x where x is the hours worked.
If she works 8 hours she will earn 20(1.05)^8
= $29.55.
The range of the amount per hour is 20 to 29.55 dollars.

Mrs. Nevin is making a costume for a school play. She needs a piece of fabric that is greater than 1/2 of a yard but less than 5/8 of a yard. Which length of fabric listed below could she use? 3/8 yard 4/7 yard 3/7 yard 2/4 yard thx so much you guys are underrated
Answer:
4/7 yards
Step-by-step explanation:
Given that :
Required fabric is > 1/2 but < 5/8
Let required fabric = x
Then ;
Converting the fractions to decimal :
1/2 = 0.5 ; 5/8 = 0.625
0.5 < x < 0.625
3/8 yards = 0.375 ;
4/7 yards = 0.571
3/7 yards = 0.429
2/4 yards = 0.5
0.5 < 0.571 < 0.625
From the options, only 4/7 yards satisfies the condition :

Step-by-step explanation:
out of the 4, which is the solution?
Answer:
x=0
Step-by-step explanation:
You can substitute 2-6y in for x to create
9y +2(2-6y) = 3
9y + 4 -12y = 3
-3y = -1
y=1/3
Then plug in y for x=2 -6y
x= 2-6(1/3)
2-2=x
x=0

9. What is the value to the solution for the system of equations y = -5X-9 and y = 2x + 5.
9514 1404 393
Answer:
(x, y) = (-2, 1)
Step-by-step explanation:
Equate the two expressions for y.
-5x -9 = 2x +5
-14 = 7x . . . . . . . .add 5x-5
-2 = x . . . . . . . . . divide by 7
Then ...
y = 2(-2) +5 = 1
The solution is (x, y) = (-2, 1).
Sulins savings is 75% of Meifens saving. if Sulin save $300, how much does Meifen save?
A) $225
B) $425
C) $325
9514 1404 393
Answer:
D) $400
Step-by-step explanation:
We are given the relations ...
s = 0.75m
s = 300
Then we can find m by equating the expressions for s:
0.75m = 300
m = 300/0.75 = 400
Meifen's savings is $400.
