Select all ordered pairs that correspond to input-output pairs of the function y = −7x + 6.
Answers
Answer:
There are no options, so i will answer in a general way.
In a function:
y = f(x)
The output is y, and the input is x, and the ordered pair is written as (x, y)
In this case, we have the function:
y = -7*x + 6
Then we need to have different inputs and then find the outputs for each.
For example, if x = 1.
y = -7*1 + 6 = -1
Then we have the ordered pair (1, - 1)
if x = 0
y = -7*0 + 6 = 6
then we have the ordered pair (0, 6)
The general ordered pair is written as:
(x, y = -7*x + 6)
or:
(x, -7*x + 6)
Where you only need to replace the value of x.

State the slope and the y-intercept in each equation. Then graph each linear equation. Be sure to fill out the entire graph and connect the points! Helpppppppppp
Answers
Answer:
Step-by-step explanation:
Use y = mx + b so:
m = 1/2
b = 3
b= 3
To graph, start at your b (y intercept) and mark that number on the y-axis. Then continue to build your line using your slope. To do that, start at your b and go down 1 and over 2. Continue until the end of the plane. Then, since it is a negative slope, work your way up 1 and over 2. Then connect your points to get your line.

Answer:
x² +3x -3 +3x/(5x² +6x +2)
Step-by-step explanation:
As with any long division, you formulate a partial quotient, then subtract the product of that and the divisor from the dividend. The result is a new dividend. You're done when the degree of the dividend is less than the degree of the divisor.
The partial quotient term is simply the ratio of the highest-degree terms in the dividend and the divisor. (That is what makes it easier than numerical long division.)

Answer:
step 1. y - y1 = m(x - x1). This is the standard line equation given a point and a slope.
step 2. parallel lines have the same slope so the slope is -4.
step 3. y - (-5) = -4(x - (-4)).
step 4. y + 5 = -4x - 16.
step 5. y = -4x - 21.

Find the equation of the line through point (−3,8) and perpendicular to y=27x+117.
Answers
Answer:
y - 8 = (-1/27)(x + 3)
Step-by-step explanation:
the slope of a line perpendicular to the given y = 27x + 117 is the negative reciprocal of 27, that is, -1/27. Using the point-slope form y - k =m(x - h) to write the new equation, we get:
y - 8 = (-1/27)(x + 3)

[tex]y = - 3x + 10[/tex]
Step-by-step explanation:
We are asked to find a line parallel to line f
[tex] - 3x - 6[/tex]
and passes through 6,-8.
Parallel lines have the same slope so our new line will also has-3 as it slope
wo using the slope intercept form let update our equation so far.
Slope intercept is
[tex]y = mx + b[/tex]
where m is the slope and b is the y intercept
plug in -3 for the slope since our new equation must be parallel.
[tex]y = - 3x + b[/tex]
Now plug 6 for x and -8 for y.
[tex] - 8 = - 3(6) + b[/tex]
[tex] - 8 = - 18 + b[/tex]
[tex]b = 10[/tex]
Our equation is
[tex]y = - 3x + 10[/tex]

A supersized laundry detergent has 60% more detergent than the regular size. The supersized has 144 ounces. How many ounces of the detergent are in the regular size

Step-by-step explanation:
The number of ounces of the detergent are in the regular size is 90 ounces.
How to find the percentage from the total value?
Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
We need to Write the percent as a fraction in simplest form
16.24%
So, we can rewrite it as;
16.24 / 100
16 and 24/100 or 16 6/25
So the percent as a fraction is 16 6/25
We are given that;
Percentage of detergent=60%
Number of ounces= 144
Now,
To find how many ounces of detergent are in the regular size, we need to use the information that the supersized has 60% more detergent than the regular size. This means that if we let x be the number of ounces in the regular size, then 144 is equal to x plus 60% of x. We can write this as an equation:
144 = x + 0.6x
To solve for x, we need to combine like terms and isolate x on one side of the equation:
144 = 1.6x x = 144/1.6 x = 90
Therefore, by the given percentage the answer will be 90 ounces.
