The math club sold 15 novelty erasers and made a profit of
$7. After another week, the club had sold a total of 25
erasers and made a profit of $15. Which equation models
the total profit, y, based on the number of erasers sold, X?
A. y - 15 = 0.8(x - 7)
B. y - 15 = 1.25(x - 7)
C. y - 7 = 0.8(x - 15)
D. y - 7 = 1.25(x - 15)
Please help me solve this guys
I’m really struggling
Answer:
(y - 1) = 4(x +1)
Step-by-step explanation:
slope = 4
B = -4
given point (-1,1)
y = 4x -4 (this is the slope intercept form)
[tex](Y - Y_{1 }) = M (X - X_{1} )[/tex] (point slope form)
(y - 1) = 4(x +1) ... that is the point slope form
PLZ ANSWER ILL GIVE BRAINLIEST
Answer:
B. neither perpendicular nor parallel
Step-by-step explanation:
to be perpendicular, the slopes have to be complete opposites. in this case, the second term would have to be y=-0.5x to be perpendicular. to be parallel, the two would have to have the same slopes; so y=2x and y=2x

Find the Average Number of Fruits eaten By Tony on a week:
Days of the week | Number of fruits
________________________________________
Sunday | 60
Monday | 40
Tuesday | 20
Wednesday | 40
Thursday | 80
Friday | 30
Saturday | 20
Answer:
41.43 fruits
Step-by-step explanation:
Average number of fruits= sum of fruits for each dat ÷ total number of fruits
[tex] \frac{60 + 40 + 20 + 40 + 80 + 30 + 20}{7} [/tex]
[tex] = \frac{290}{7} [/tex]

Paul's company rents cars to people who are at least 25 years old. Which graph best represents the possible ages of people who can rent cars from Paul's company?
A number line with an open circle on 25, with shading to the right.
A number line with a closed circle on 25, with shading to the right.
A number line with an open circle on 25, with shading to the left.
A number line with a closed circle on 25, with shading to the left.
Answer:
A number line with a closed circle on 25, with shading to the right.
Explanation:
A closed circle means "greater than or equal to" or "less than or equal to".
A open circle means "less than" or "greater than"
Therefore, since the question says: "who are at least 25 years old", a closed circle is the correct answer.
And says it says "at least 25 years old" it means that it shaded to the right, and that the circle is on the number 25.
Answer:
A number line with a closed circle on 25, with shading to the right.

PLEASE HURRY Aline has a slope of -1/2 and a y-intercept of -2. What is the x-intercept of the line?
Answer:
x- intercept = - 4
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 )
Here m = - [tex]\frac{1}{2}[/tex] and c = - 2 , then
y = - [tex]\frac{1}{2}[/tex] x - 2 ← equation of line
To find the x- intercept let y = 0
0 = - [tex]\frac{1}{2}[/tex] x - 2 ( add 2 to both sides )
2 = - [tex]\frac{1}{2}[/tex] x ( multiply both sides by - 2 to clear the fraction )
- 4 = x
The x- intercept is - 4

Complete the function for this graph.
Answer:
k(x) = -2|x - (-3)| + 4
Step-by-step explanation:
Parent function for the graph is,
f(x) = |x|
If the parent function is vertically stretched by a scale factor of 2,
New function will be,
g(x) = 2|x|
If the function 'g' is reflected across x-axis,
h(x) = -2|x|
If the function 'h' is translated 3 units left and 4 units upwards, new function will be,
k(x) = -2|x - (-3)| + 4

Coordinates (x, y)Terms/CoefficientsSolving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
y = x + 8
x + y = 2
Step 2: Solve for x
Substitution
Substitute in y [2nd Equation]: x + x + 8 = 2Combine like terms: 2x + 8 = 2[Subtraction Property of Equality] Subtract 8 on both sides: 2x = -6[Division Property of Equality] Divide 2 on both sides: x = -3Step 3: Solve for y
Substitute in x [1st Equation]: y = -3 + 8Add: y = 5Answer:
x = - 3
y = 5
Step-by-step explanation:
y = x + 8 ------(I)
x + y = 2 -------------(II)
Substitute y = x + 8 in equation (II)
x + x + 8 = 2
Combine like terms
2x + 8 = 2
Subtract r from both sides
2x = 2- 8
2x = -6
Divide both sides by 2
x = -6/2
x = -3
Plug in x = -3 in equation (I)
y = -3 + 8
y = 5

If the measure of angle 5 is (3x + 50) degrees and the measure of angle 6 is (5x + 16) degrees, what value of x will guarantee equation AB \\ DE
Answer:
x = 17
Step-by-step explanation:
If AB // DE, then angle 5 and angle 6 are alternate interior angle and they should be congruent.
5x + 16 = 3x + 50
Subtract 16 from both sides
5x = 3x + 50 - 16
5x = 3x + 34
Subtract 3x from both sides
5x - 3x = 34
2x = 34
Divide both sides by 2
x = 34/2
x = 17
Answer:
To AB \\ DEangle 5 should be equal to angle 63x + 50 = 5x + 16
5x - 3x = 50-16
2x = 34
x = 17
