Answer:
y = -0.3x + 105
Step-by-step explanation:
x1 - x2 / y1 - y2 is the method to use to find the answer, so it
= (94.5-97.5) / (35-25) which
= (-3) / (10) which = -0.3.
That is m for ya, and for b,
Sub the first point (25, 97.5) into the equation of this line:
97.5 = (-0.3)*(25) + b => b = 97.5 - (-7.5) = 105
In conclusion, the equation is y = -0.3x + 105.
Factor: 48q³ - 24q² + 3q

Answer:
155α+81
Step-by-step explanation:
There are two rectangles:
1
area₁ =- (15α+8)(7) = 15α*7 + 8*7 = 105α+56
2
area₂ = (10α+5)(12-7) = (10α+5)(5) = 10α*5 + 5*5 = 50a + 25
Total area = area₁ + area₂
Total area = (105α+56)+(50α+25)
Total area = 105α + 50α + 56 + 25
Total area = 155α + 81

The total cost for laundry service, in dollars, depends on the weight of the laundry, in pounds. This relationship is proportional, as it costs $24.65 for 29 pounds of laundry and $36.55 for 43 pounds of laundry.
In words, describe the graph of the proportional relationship.
A line from (0, 0) going through (24.65, 29) where the x-axis is labeled Weight (in pounds) and the y-axis is labeled Cost (in dollars)
A line from (0, 0) going through (29, 24.65) where the x-axis is labeled Cost (in dollars) and the y-axis is labeled Weight (in pounds)
A line from (0, 0) going through (43, 36.55) where the x-axis is labeled Cost (in dollars) and the y-axis is labeled Weight (in pounds)
A line from (0, 0) going through (43, 36.55) where the x-axis is labeled Weight (in pounds) and the y-axis is labeled Cost (in dollars)
The graph of this proportional relationship is described by: A. line from (0, 0) going through (24.65, 29) where the x-axis is labeled Weight (in pounds) and the y-axis is labeled Cost (in dollars).
What is a graph?In Mathematics, a graph simply refers a type of chart that is typically used to graphically represent data points on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate (x-axis) and y-coordinate (y-axis).
Generally speaking, the graph of any proportional relationship is always characterized by a straight line with the data points passing through the origin (0, 0) because as the values on the x-axis increases or decreases, the values on the y-axis increases or decreases simultaneously.
By critically observing graph of this proportional relationship (see attachment), we can logically deduce that it passes through both points (24.65, 29) and (36.55, 43).

Answer:
Maybe congruent
Step-by-step explanation:
You have two isosceles triangles, one with a marked base angle of 49° and the other marked with an a.pex angle of 82°. One side of one triangle is marked as 11 cm.
CongruenceIn order for the triangles to be congruent, corresponding angles must be congruent, and corresponding sides must be congruent.
AnglesEach isosceles triangle has two congruent base angles and an a.pex angle that total 180°. The base angles in the triangle on the right are ...
2x +82° = 180°
2x = 98°
x = 49° . . . . . . congruent with the base angles of the other triangle
Corresponding angles of the triangles are congruent, so the triangles are similar.
SidesOnly one side in the diagram is marked, so we cannot make any claim regarding the measures of corresponding sides in the two triangles. If corresponding sides are congruent in the similar triangles, then the triangles will be congruent.
We can only conclude that the triangles may be congruent.

Blake was a little concerned as he stood in the middle of the overcrowded elevator. The sign clearly stated that the total weight in the elevator could not exceed 2,000 pounds.
Write an inequality to show the weight limit for the elevator.
A) w > 2,000
B) w < 2,000
C) w ≤ 2,000
D) w ≥ 2,000
Answer: C) w ≤ 2,000
Step-by-step explanation:
We know for a fact that it is not A or D, because this means that the elevator WOULD be able to handle weight more than or equal to 2,000 lbs.
This leaves us A and C.
The question states that the weight could not exceed 2,000 pounds, meaning that ≤ will be used. This gives us w ≤ 2,000. The total weight in the elevator has to be less than or equal to 2,000 pounds.

A wheat farmer plows 5 acres of land and collects 135 bushels of wheat. The next day, the farmer plows 8 acres of land and collects 216 bushels of wheat.
Is there a proportional relationship between the number of bushels of wheat collected and the number of acres plowed over the two days? Explain.
Yes, it is proportional because the farmer collected 7 bushels for every 1 acre plowed.
Yes, it is proportional because the farmer collected 27 bushels for every 1 acre plowed.
No, it is not proportional because both variables cannot be zero at the same time.
No, it is not proportional because all ratios between the number of bushels collected and the number of acres plowed are not equivalent.
Answer:
Your answer would be the second one:)
Step-by-step explanation:
Yes, it is proportional because the farmer collected 27 bushels for every 1 acre plowed. Option B is correct.
As mentioned in the question, a wheat farmer plows 5 acres of land and collects 135 bushels of wheat. The next day, the farmer plows 8 acres of land and collects 216 bushels of wheat.
What is proportionality?Proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
Let the number of land plows be x, and the number of bushels collected be y.
According to the question,
If the relationship between the plows and bushels is proportional then the ratio of bushels to plows or vice versa should be constant,
So,
y/x= k
or,
x₁/x₂ = y₁/y₂
Now,
5/8 = 135/216
5/8 = 5/8
And the value of the constant of proportionality is given as,
k = y/x
k =135/5
k = 27 bushels for every 1 acre plowed.
Thus, Yes, it is proportional because the farmer collected 27 bushels for every 1 acre plowed. Option B is correct.

6y + 14 = -5y - 8. what is the value of y?
Answer:
y=-2
Step-by-step explanation:
Let's solve your equation step-by-step.
6y+14=−5y−8
Step 1: Add 5y to both sides.
6y+14+5y=−5y−8+5y
11y+14=−8
Step 2: Subtract 14 from both sides.
11y+14−14=−8−14
11y=−22
Step 3: Divide both sides by 11.
11/11y=-22/11
y=-2
answer:
y=-2

The value of y for the expression 6y + 14 = -5y - 8 will be y=-2.
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Let's solve your equation step-by-step.
6y+14=−5y−8
Step 1: Add 5y to both sides.
6y+14+5y=−5y−8+5y
11y+14=−8
Step 2: Subtract 14 from both sides.
11y+14−14=−8−14
11y=−22
Step 3: Divide both sides by 11.
11/11y=-22/11
y=-2
Hence, the value of y is equal to -2.
