Step-by-step explanation:
The graph represents a mechanic’s labor costs for a given number of hours of car repair. A graph titled Car Repairs. The horizontal axis shows Labor Time (hours) numbered 0.25 to 2.5, and the vertical axis shows Labor Costs (dollars), numbered 25 to 250. The line remains constant at $50 dollars over 1 hour, then increases sharply. The line remains at 50 dollars from 0 to 1 hour, then move upward to end at 175 dollars at 2.5 hours.
Answer:
A: All repairs requiring 1 hour or less have the same labor cost.

Amira is told there is a trick to finding the slope within an equation in standard form, Ax+By=C. She is told she can rewrite this equation in slope-intercept form, y=mx+b, to find the pattern. She correctly rewrites the equation 7x+9y=14 in slope-intercept form as y=− 7/9x +14/9. Which answer explains the pattern for how to find the slope using an equation in standard form?
A. In slope-intercept form, the slope is 14/9. These values are C and A, but with the opposite sign, so the slope of the line from the equation in standard form is − C/A.
B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.
C. In slope-intercept form, the slope is 14/9. These values are C and B, but with the opposite sign, so the slope of the line from the equation in standard form is − C/B.
D. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − B/A.
Answer:
B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.
Step-by-step explanation:
Let's convert the standard equation into slope-intercept form:
Ax + By = C ⇒ subtract Ax from both sidesBy = -Ax + C ⇒ divide both sides by By = -A/Bx + C/B ⇒ converted to slope- intercept formAs we see the slope is -A/B
The equation 7x + 9y = 14 is converted as:
y = -7/9x + 14/9, where the slope is -7/9Looking at the answer options and the correct one is option B, where both identification of slopes match.
B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.What is the value of m in the figure below? If necessary, round your answer to

A. 8.5
B. 8.2
C. 13
D. 4
Answer:
B. 8.2
Step-by-step explanation:
[tex] In\: \triangle ABC, \:\angle ABC= 90\degree \: \&\: BD\perp AC[/tex]
So, by geometric mean property.
[tex] BD = \sqrt {AD\times CD} \\
BD = \sqrt {13\times 4}\\
BD = \sqrt {52}\\
Next\: in \: \triangle BDC, \:\\
By\: Pythagoras \: theorem \\
m^2 = BD^2 + CD^2 \\
m^2 = (\sqrt {52}) ^2 + (4)^2 \\
m^2 =52 + 16\\
m^2 =68\\
m =\sqrt{68} \\
m = 8.24621125\\

Right triangle ABC is on a coordinate plane. Segment AB is on the line y = 2 and is 3 units long. Point C is on the line x = −1. If the area of ΔABC is 6 square units, then find a possible y-coordinate of point C.
A: 6
B: 7
C: 8
Answer:
A. 6
Step-by-step explanation:
Segment AB is on the line y = 2 and is 3 units long.
Point C is on the line x = −1.
FIND:
If the area of ΔABC is 6 square units, then find a possible y-coordinate of point C.
SOLUTION:
Area of a triangle = 1/2 b * h
segment AB is a horizontal line
the base of our triangle and point C is somewhere on the height.
If we can find the height of the triangle, we can add or subtract that height from y = 2 to get the possible y coordinate of point C.
We know that the x coordinate is -1 so,
6 = 1/2 (3) h
12 = 3h
h = 4
we can either add 4 or subtract 4 to the y coordinate of 2 to get the possible y coordinate of point C.
option 1
2 + 4 = 6 so the coordinate for C could be (-1, 6) or
option 2
2 - 4 = -2 so the coordinate for C could also be (-1, -2).
Since -2 is not in our choices but 6.
therefore,
the answer would be A. 6

50 POINTS NOW!! Which inequality is equivalent to the given inequality plz help
-4(x + 7) < 3(x - 2)
Let's simplify this inequality
-4x - 28 < 3x - 6
Subtract 3x from both sides and add 28 to both sides
-7x < 22
Answer choice B is correct
Answer:
-7x < 22
Step-by-step explanation:
1. -4(x+7) < 3(x-2)
distribute -4 to x and 7, distribute 3 to x and -2.
2. -4x-28 < 3x-6
add 28 to 28 to cancel it out, add 28 to -6.
3. -4x < 3x+22
subtract 3x from 3x to cancel it out, subtract -3x from -4x.
4. -7x < 22
the final product! the answer is B. -7 < 22. since there was no multiplication or division, there's no need to switch < to >. hope this helps! :)

What two numbers have a product of -2 and a sum of 7
Greetings from Brasil...
According to the statement of the question, we can assemble the following system of equation:
X · Y = - 2 i
X + Y = 7 ii
isolating X from i and replacing in ii:
X · Y = - 2
X = - 2/Y
X + Y = 7
(- 2/Y) + Y = 7 multiplying everything by Y
(- 2Y/Y) + Y·Y = 7·Y
- 2 + Y² = 7X rearranging everything
Y² - 7X - 2 = 0 2nd degree equation
Δ = b² - 4·a·c
Δ = (- 7)² - 4·1·(- 2)
Δ = 49 + 8
Δ = 57
X = (- b ± √Δ)/2a
X' = (- (- 7) ± √57)/2·1
X' = (7 + √57)/2
X' = (7 - √57)/2
So, the numbers are:
(7 + √57)/2and

frank is 5 years younger than twice the age of his cousin Alonso. Frank is 17 years old. Which equation could be used to determine a, alonzos age?
Answer:
Hi there!
Your answer is:
17= 2A-5
Alonzo is 11
Step-by-step explanation:
Frank=2A -5
Frank = 17
17= 2A-5
A = Alonzo's age
Alonzo's age is:
17= 2A-5
+5
22 = 2A
/2
11= A
