Step-by-step explanation:
y = mx + c
8 - 7x = 4y
4y = 8 - 7x
y = (8 - 7x)/4
= 2 - 7/4x
y = -7/4x + 2
Slope = m = -7/4
Answer:
slope = - [tex]\frac{7}{4}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
8 - 7x = 4y, that is
4y = - 7x + 8 ( divide all terms by 4 )
y = - [tex]\frac{7}{4}[/tex] x + 2 ← in slope- intercept form
with slope m = - [tex]\frac{7}{4}[/tex]

(6x - 3) - (-3x + 2)
Answer:
Step-by-step explanation:
Simplifying
6x + -3 = (3x + -2)
Reorder the terms:
-3 + 6x = (3x + -2)
Reorder the terms:
-3 + 6x = (-2 + 3x)
Remove parenthesis around (-2 + 3x)
-3 + 6x = -2 + 3x
Solving
-3 + 6x = -2 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-3 + 6x + -3x = -2 + 3x + -3x
Combine like terms: 6x + -3x = 3x
-3 + 3x = -2 + 3x + -3x
Combine like terms: 3x + -3x = 0
-3 + 3x = -2 + 0
-3 + 3x = -2
Add '3' to each side of the equation.
-3 + 3 + 3x = -2 + 3
Combine like terms: -3 + 3 = 0
0 + 3x = -2 + 3
3x = -2 + 3
Combine like terms: -2 + 3 = 1
3x = 1
Divide each side by '3'.
x = 0.3333333333
Simplifying
x = 0.3333333333
Which expression represents (−21−−−−√5)6 in rational exponent form? (−21)6/5 −215/6 (65)−21 (56)−21
Answer:
[tex](-21)^\frac{6}{5}[/tex]
Step-by-step explanation:
Which expression represents [⁵√(−21)]⁶ in rational exponent form?
Solution:
Rational numbers are numbers which can be expressed as fractions in the form a / b, where a, b are integers and b is not equal to zero.
A rational exponent is an exponent that is a fraction. For example √2 = [tex]2^\frac{1}{2}[/tex].
When expressing a number in rational exponent form, the numerator of the fractional exponent refers to a normal power, but the denominator refers to the root.
[tex][\sqrt[5]{(-21)}]^6 = (-21)^\frac{6}{5}[/tex]
The scatterplot below shows the number of hours that some high school students spend on working and on video games.
A graph title Working and Video games has weekly working hours on the x-axis and weekly hours of video games on the y-axis. Points are grouped together and decrease.
Which statement about the scatterplot is true?
In general, the number of hours spent working does not affect the number of hours spent on video games.
In general, the amount of weekly time spent working is equal to the amount of weekly time spent on video games.
As the amount of time spent working increases, the amount of time spent on video games increases.
As the number of hours spent working increases, the amount of time spent on video games decreases.

respectively. How many gallons of each are needed?
Answer:
salt + salt = salt
0.13x +3.3-0.33x =2.5
-0.20x=-0.8
x= 4 gallons (amt of 13% solution to be mixed)

If ΔABC is an equilateral triangle with, AB = 2x + 17, BC = 6x - 19, AC = 4x-1, find x and the measure of each side
Answer:
[tex]x=9, AB=BC=AC=35[/tex]
Step-by-step explanation:
Equilateral triangles have 3 congruent sides, so all 3 sides have the same length. Therefore, we know that [tex]AB=BC=AC[/tex]. We are given the lengths of all 3 sides in terms of [tex]x[/tex], but we only need to set two of them equal to each other to solve for [tex]x[/tex]. Let's use [tex]AB[/tex] and [tex]BC[/tex] to solve for [tex]x[/tex]. We know that [tex]AB=BC[/tex], [tex]AB=2x+17[/tex], and [tex]BC=6x-19[/tex]. Therefore, we can write the following equation to solve for
[tex]AB=BC\\2x+17=6x-19[/tex] (Substitute given values into equation)
Solving for [tex]x[/tex], we get:
[tex]2x+17=6x-19\\2x+17-17=6x-19-17[/tex] (Subtract [tex]17[/tex] from both sides of the equation to isolate constants)
[tex]2x=6x-36[/tex] (Simplify)
[tex]2x-6x=6x-36-6x[/tex] (Subtract [tex]6x[/tex] from both sides of the equation to isolate [tex]x[/tex])
[tex]-4x=-36[/tex] (Simplify)
[tex]\frac{-4x}{-4}=\frac{-36}{-4}[/tex] (Divide both sides of the equation by [tex]-4[/tex] to get rid of [tex]x[/tex]'s coefficient)
[tex]x=9[/tex] (Simplify)
Therefore, [tex]AB=2x+17=2*9+17=18+17=35[/tex], and [tex]AB=BC=AC=35[/tex]. Hope this helps!

Price-club sells a 12-ounce box of crackers for $2.59 and Shop Mart sells a 1-pound box of crackers for $4.68. The unit price at Price-Club is $ per ounce, and the unit price at Shop Mart is $ per ounce.
Answer:
$0.216 and $0.293
Step-by-step explanation:
Given,
Price club sells 12 ounce box = $2.59
Shop mart sells a 1 pound box = $ 4.68.
We have to find the unit price at Price club and Shop mart.
We know that 1 Pound = 16 ounce
Unit price at Price-club = [tex]\dfrac{2.59}{12}[/tex]
= $0.216
Unit price at Shop Mart= [tex]\dfrac{4.68}{16}[/tex]
= $0.293
because I got this question too. On odysse.yware.
Answer:
0.21 and 0.19
Step-by-step explanation:
It's simple, just divide it.
Divide 2.59 by 12 and divide 4.68. Then round the answers to the closest number in the choices. That's your answer buddy!

Answer: 262.6
Step-by-step explanation: Well if she sold 110 hamburgers on tuesday for $545 That is a simple division equation (545/110). After dividing the answer would be how much each hamburguer cost on its own ( 4.954545454545455), you would then multiply that by the number of hamburgers she sold (53) and get your answer. (262.5909090909091) I am not quite sure where she wants us to round the answer to. so I just did the tens place.

For each of the 6 pairs of triangles below, determine if the triangles can be proved congruent. If yes, tell which of the patterns it fits (SSS, SAS, ASA, or AAS)
Answer:
a. is congruent by SSS
b. is congruent by AAS
c. is congruent by ASA
d. is congruent by SAS
Step-by-step explanation:
a. is SSS because all sides are marked
b. is AAS because the point where the two triangles meet are vertical angles and the one side of the triangle is marked congruent making AAS
c. is ASA because the angles are on segment FG and segment BC and there is a congruent line in between the two angles making ASA
d. is SAS because the triangles share the segment QS and when two triangles share a segment, that segment is congruent. the outside segment is congruent and then there is an angle and then the inside segment is congruent

Find the common difference of the arithmetic
sequence 13,9,5,
Answer: -4
Step-by-step explanation:
13 - 9 = 4
9 - 5 = 4
so, we can see that it is decreasing by 4 each time.
Answer:
common difference is -4
Step-by-step explanation:
The common difference is the amount we add between terms
13 + d = 9
Subtract 13 from each side
13+d-13 = 9-13
d = -4
Check
9+d = 5
9 + -4 = 5
5= 5
This is true so the common difference is -4
