(-1, 4) and (0,-1) writing out linear equations giving two points
Answer:
The equation is y = -5x - 1.
Step-by-step explanation:
1. Find the slope using the formula. Slope = (4 + 1) / (-1 - 0) which is equal to 5 / -1 which is -5.
2. Use the slope-point formula to construct an equation. The equation is y - 4 = -5 * (x + 1)
3. Simplify. We would get y = -5x - 5 + 4, which is y = -5x - 1.
Answer: The equation is y = -5x - 1.

The line y+2x=b is perpendicular to a line that passes through the origin. If the two lines intersect at one point (k+2,2k), what is the value of k?
Answer:
The line y+2x=b is perpendicular to a line that passes through the origin. If the two lines intersect at the point (k+2,2k)
Step-by-step explanation:
that should be right
The value of k is 2/3.
We have,
To determine the value of k, we need to find the equation of the line passing through the origin that is perpendicular to the line y + 2x = b.
The given line, y + 2x = b, can be rewritten in slope-intercept form
(y = mx + c) by solving for y:
y = -2x + b
Since the line passing through the origin is perpendicular to this line, its slope will be the negative reciprocal of the slope of the given line.
The given line has a slope of -2, so the perpendicular line will have a slope of 1/2.
Using the point-slope form (y - y1 = m(x - x1)) with the point (k + 2, 2k), we can write the equation of the perpendicular line passing through the origin as:
y - 0 = (1/2)(x - 0)
y = (1/2)x
To find the value of k, we equate the y-values of the two lines at the point of intersection:
(1/2)x = 2k
x = 4k
Since the x-coordinate of the point of intersection is k + 2, we can set it equal to 4k and solve for k:
k + 2 = 4k
2 = 3k
k = 2/3
Therefore,
The value of k is 2/3.

Milo pays $3 per pound for dog food at Pat's Pet
Palace. The graph below represents the cost per
pound of food at Mark's Mutt Market. At which
store will Milo pay a lower price per pound for
dog food?
Answer:
Pat Pet's Palace
Step-by-step explanation:
Price of dog food at Pat Pet's Palace = $3 per pound
Price of dog food at Mark's Mutt Market can be estimated using the graph given.
The graph is a proportional graph, thus, the constant of proportionality between cost and pound = y/x
Using the coordinates of a point on the line, (2.5, 10), constant of proportionality or unit rate = y/x = 10/2.5 = 4.
This means the price of dog food at Mark's Mutt Market is $4 per pound.
Therefore, Milo would pay a lower price per pound for dog food at Pat Pet's Palace.

Answer:
x = 3, the error is that the -2x should be added.
Step-by-step explanation:
The -2x should be added to the left side.

Answer lest edited 3:11 PM Central, 11/24/2020
Answer:
x=5
Step-by-step explanation:
Correct way:
Add 2x to 3x ( 5x )
3x-7=8
Add 7 to 8 ( 15 )
3x=15
Divide 15/3
x= 5
What was wrong:
You need to combine like terms and put the variable on the left side of the equation and then follow the steps above. You also forgot to divide.

A restaurant offers delivery for their pizzas. The total cost is a delivery fee added to the price of the pizzas. One customer pays $25 to have 2 pizzas delivered. Another customer pays $58 for 5 pizzas. How many pizzas are delivered to a customer who pays $80
Answer:
7 pizzas
Step-by-step explanation
First we subtract 58-25=33
Then we subtract 5-2=3
Now, we have 33 over 3 so we divide them and we get 11
So, that means that each pizza costs $11 and the fee that they charge for each pizza is 3.
So if the customer pays $80 that means that he bought 7 pizzas and he payed $3 fee.

A theater has 20 seats in the first row, 22 in the second row, 24 in the third row, and so on for 25 rows. How many seats are in the last row?
If the number of seats that are in the last row is 1100 seats.
Number of seatsFirst row=20
Second row=22
Third row=24
A.P = 20,22,24,…
a=20
d=22−20=2
n=25
Using the formula of the sum of the first n terms of an A.P
Sn=n/2[2a+(n−1)d]
S25= 25/2 [2×20 +(25-1) 2]
S25 = 12.5 [40 +24 ×2]
S25= 12.5 [88]
S25= 1100
Therefore If a theater has 20 seats in the first row, 22 in the second row, 24 in the third row, and so on for 25 rows. The number of seats that are in the last row is 1100 seats.
