Answer:
y+6 = 7/3(x-1)
Step-by-step explanation:
The point slope form of the equation is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y - -6 = 7/3( x -1)
y+6 = 7/3(x-1)
Answer:
D
Step-by-step explanation:
The general form of a line in point-slope form is y-k=m(x-h), where k is the y coordinate any point on the line, h is the x coordinate, and m is the slope of the line. Therefore, the equation of this line would be y+6=7/3(x-1), or choice D. Hope this helps!

Answers
Answer:
7x + 96 = 180
Step-by-step explanation:
We are given that the right side of the equation should be 180 because that is equal to the sum of the triangle's interior angle measures.
We can solve for the left side by adding the triangle's interior angle measures.
(2x + 1) + (5x + 5) + 90
Remember that a right angle is 90°.
All we need to do from here is combine like terms:
= (2x + 5x) + (1 + 5 + 90)
= 7x + 96
So, the equation that represents the model is:
7x + 96 = 180
Answer:
C) 7x + 96° = 180
Step-by-step explanation:
their is one right angle and 2 equations. The sum of the interior angle is 180
90° + 2x + 1 + 5x + 5 = 180
Combine like terms
90 + 1 + 5 = 96
2x + 5x = 7x
7x + 96° = 180

Answer:
Y= mx + b
so Y = 1/3x + 2
just substitute
Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.
Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

Answer:
7600 sq. yd.
Step-by-step explanation:
Formula for the 'Area of a triangle' is:
1/2 * base * height
The area of the triangle is:
A = 1/2 * b * h
A = 1/2 * 300 * 40
A = 150 * 40
A = 6000
Formula for the 'Are of a square' is:
Length squared
The Are of the square is:
A = L * L
A = 40 * 40
A = 1600
Then we can add it together:
A = 6000+1600
A = 7600 sq. yd.

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

I would choose lelia because she might have taken longer but maria ran 1 lap lelia ran 3 so lelia can run 2 1/4 (or (1/3) times faster
Answer:
Lelia should be chosen.
Step-by-step explanation:
Leila: 3 laps is going to be 3/5 x 3, which is 9/5. So she can run 1 4/5 in 7 minutes.
Maria: 1 lap is going to be 3/5. So she can run 3/5 in 3 minutes.
If you multiply 3/5 by 2, you're going to get 6/5 in 6 minutes, and then divide it by 6, which is going to give you 1/5 of a lap in 1 minute, multiply that by 7, and get 7/35. This is for Maria. If you divide 9/5 by 7, you're going to get 9/35. This is for Lelia.
Maria: 7/35 of a lap in 1 minute.
Lelia: 9/35 of a lap in 1 minute.
Lelia should be chosen.

D. The cost of attending a concert for c groups of people for $6.50 each.
Answers
Answer:
B
Step-by-step explanation:
You pay $117 no matter how many kids show up and then you pay an additional fee of 6.50 per kid.
1 kid
y = 6.50(1) + 117
y = 123.50
If 10 kids come
y = 6.50(10) + 117
y = 65 + 117
y = 182
You can use this equation to help you figure out how much it will cost you depending on how many kids you invite.

Answers
Answer:
It would be constant.
Step-by-step explanation:
Since there is no x value, the line will have no slope and just be horizontal about y= -2.
If we draw the graph we will see that the function is a straight line parallel to the x-axis.
The graph y = -2 is best described as a constant function.
Option C is the correct answer.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
A function:
y = -2
To graph the function we will find the coordinates of the function y = -2.
For x = 0,
y = -2
For x = 1,
y = -2
For x = 2,
y = -2
For x = 3,
y = -2
We will see that for all x values the y value is -2.
If we draw the graph we will see that the function is a straight line parallel to x-axis.
Thus,
The graph y = -2 is best described as a constant function.
