Use the point and the slope to graph cach line. Write the equation of the line.
The line passes through point (-1, 4) and has slope - 2.
Answer:
y=-2x+2
Step-by-step explanation:
We use the formula
y=mx+b, where m is the slope, b is the y intercept, and x&y are the coordinates.
We know that one point is (-1, 4)
and the slope is -2.
We are trying to find b.
In order to do that, we plug in what we know:
so,
4=-2(-1)+b
4=2+b
4-2=b
b=2
So now we go back to the original equation and use b as our value'
y=-2x+2

what is -9/14+2/7 as a fraction in simplest form
_________
[tex] \: [/tex]
[tex] - \frac{9}{14} + \frac{2}{7} = ...[/tex]
[tex] = \frac{2}{7} - \frac{9}{14} [/tex]
[tex] = \frac{(28 - 63)}{98} [/tex]
[tex] = \frac{ -35 }{98} [/tex]
[tex] = \boxed{ \bold{ - \frac{35}{98}}} [/tex]
Answer:
5/14
Step-by-step explanation:
-9 is just 9 so that makes 9/14 - 2/7.
Multiply 7 by 2 and that makes 14, do the same with the numerator and that makes 4/14 and 9/14 - 4/14 = 5/14

Answer:
27y^12 cubic feet
Step-by-step explanation:
Put the given side length into the formula and simplify according to the rules of exponents.
V = (3y^4)^3 = 3^3·y^(4·3) = 27y^12
The volume of the vault is 27y^12 cubic feet.

The answer is no!
There can't be 20 students in that class because the ratio is 4:9 so its either 4 boys and 9 girls or 4 girls and 9 boys.This is a total of 13 students because (4+9=13).The answer is That there can not be 20 students in that class because there is only 13 students.
A drawer contains black socks and white socks. 80% of the socks are white socks. A number generator simulates randomly selecting 10 socks from the drawer. The number generator is used 10 times and the number of white socks in each trial is shown in the dot plot.
Which description is correct about the number generator being fair or not?
The number generator is fair. It picked white socks half of the time.
The number generator is not fair. The correct percentage of white socks was not chosen at all.
The number generator is not fair. In three experiments, it picked white socks 90% of the time.
The number generator is fair. It picked the approximate percentage of white socks most of the time.
Answer:
The number generator is fair. It picked the approximate percentage of white socks most of the time.
Step-by-step explanation:
Just took the test :3
Description about the number generator : The number generator is fair. It picked the approximate percentage of white socks most of the time.
What is randomly selection?Random selection is a part of the sampling technique in which each sample has an equal probability of being chosen.
According to question
White socks = 80%
Black socks = 20%
Randomly selecting 10 socks from the drawer .
Process repeated 10 times
According to dots on plot
Number white socks was selected in each round is 7,7,7,8,8,8,8,9,9,9 .
If we evaluate the number generator :
80% of the socks are white, and each trial selects 10 socks. 80% of 10 is 8, which is what the number generator picked most of the time.
That means The number generator is fair.
Hence, The number generator is fair. It picked the approximate percentage of white socks most of the time.

A hamburger shop sold a combined total of 304 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold?
Answer: 76 hamburgers
Step-by-step explanation:
first we will write an equation:
x+3x=304
which simplified turns in 4x=304
x=76
now go back to our equation and solve.
3x is cheese burgers= 228 cheeseburgers
x is hamburgers =76 hamburgers

1. Lucy monitors the position of a large fish in the ocean with a measuring tool. The tool records the depth (how deep the level) of the fish. Initially, the fish swims at a depth of 14 feet below sea level. Suddenly the fish rises 8 feet.
(a) What expression represents the position of the fish relative to sea level after it rises 8 feet?
(b) What is the position of the fish after it rises 8 feet relative to sea level? Show your work. Answer in a complete sentence.
Hint: Draw and label a picture to see and show what is happening.
Answer:
A) -14 + 8 = 6
B) The fish is at -6 feet below the sea level after it rises 8 feet because -14 (14 feet below 0) plus the 8 feet it rises is -6 feet or 6 feet below the sea level.

Answer:
16 ==>> Length of PR
4 ==>> Value of A
3 ==>> Value of B
6 ==>> Length of QS
Step-by-step explanation:
==>> Since PQRS is a parallelogram the diagonals are symmetrically split by a shared midpoint: T
--
==>> Thus the values of A & B can be found by setting the sides to equal each other.
2B - 3 = B [add 3 and subtract B from both sides]
B = 3
A + 4 = 2A [subtract A from both sides]
4 = A
--
==>> Then to find the length of the diagonals: Plug the variables in and add both sides.
2(3) - 3 + (3) =6
(4) + 4 + 2(4) =16
The correct matching of the elements to their values are:
16 ==>> Length of PR4 ==>> Value of A3 ==>> Value of B6 ==>> Length of QSWhat is a Parallelogram?This refers to the plane that has four sides and their opposite sides are parallel.
Hence, because PQRS is a parallelogram, the diagonals are symmetrically split by a shared midpoint:
This means that the values of A & B can be found by setting the sides to equal each other.
2B - 3 = B
B = 3
A + 4 = 2A
4 = A
Length of the diagonals:
2(3) - 3 + (3) =6
(4) + 4 + 2(4) =16

Glenn bought a $5 coffee and four magazines at the airport. If he spent a total of $25, how much did each magazine cost?
Answer:
Each magazine would cost 5 dollars.
Step-by-step explanation:
If he originally started with $25 then spent $5 he would then have $20 dollars left.
If he then bought 4 magazines using the last of his $20 (ignoring sales tax) you would have to divide $20 by 4 to get a total of $5 dollars for each magazine.
