Answer:
A linear equation can be written in many ways, so the way we can use to solve a system of linear equations depends on the form the system is written. There are several methods to do this, the more common are: Method of Equalization, Substitution Method, Elimination Method.
Slope:
what is the slope?
Answer: -2
Step-by-step explanation:
So basically I located the y-intercept first. Where is that? At the point (0,-2). Now from there, I found the nearest point on an intersecting grid line, in this case it would be (-1,0). So from the y-intercept, I looked at how many spaces I would have to move to get to (-1,0). You would have to go up 2 spaces and to the left 1 space. This is also written as 2/-1. Simplify this and you get -2! Hope this helped!
Answer:
the slope is -2
Step-by-step explanation:
To find the slope you use rise over run, rise/run. The rise is -8 and the run is 4, 4/-8=-2.

Answer:
y = -11
Step-by-step explanation:
The slope-intercept form of an equation of a line:
y = mx + b
m - slope
b - y-intercept → (0, b)
We have the slope m = 0 and the point (0, -11) → b = -11.
Substitute:
y = 0x - 11 = -11
It's a horizontal line.
Answer:
Step-by-step explanation:
Slope-intercept form: [tex]y=mx+b[/tex] when [tex]b[/tex] is the y-intercept and [tex]m[/tex] is the slope
The slope is already given in the question: 0
The y-intercept is the value of y when x is equal to 0. We can see that the given point, (0,-11) also tells us this. When x is equal to 0, y is equal to -11. Therefore, the y-intercept of the line is -11.
Finally, we plug the slope and the y-intercept back into the original equation.
[tex]y=mx+b\\y=0x+(-11)\\y=0-11\\y=-11[/tex]

LMNO is a parallelogram. If NM = x + 15 and OL = 3x + 5 find the value of x and then find NM and OL.
Answer:
x = 5 unit
NM = 20 unit
OL = 20 unit
Step-by-step explanation:
Given:
LMNO is parallelogram
NM = x + 15
OL = 3x + 5
Find:
x and NM and OL
So,
NM = OL
x + 15 = 3x + 5
2x = 10
x = 5
So,
NM = x + 15 = 5 + 15 = 20
OL = 3x + 5 =3(5)+5 = 20

o $2; the cost per muffin
O $2; the cost per order
$15; the cost per order
Answer:
:)
Step-by-step explanation:
It should be $2; the cost per muffin
The cost of one muffin is $2.
What is subtraction?Subtraction is mathematic operation. Which is used to remove terms or objects in expression.
Given, $15 is delivery cost of muffins.
That means the if x is the cost of one muffin then
Total cost = nx + $15
,where n is the number of muffins.
Now,
for n = 1
The total cost of one muffin is :
17 = x + 15
x = 2
Therefore, the cost of one muffin is $2.

Each time Miranda goes to the store she plans to spend \$7$7dollar sign, 7, and each time Savannah goes to the store she plans to spend \$9$9dollar sign, 9. A few weeks from now, Miranda and Savannah are surprised to find out that they have spent the exact same total amount of money at the store. What is the least possible number of times that Miranda has been to the store
Answer:
9 visits
Step-by-step explanation:
Given that:
Amount spent by Miranda per visit = $7
Amount spent by Savanah per visit = $9
To obtain the least number of visits by Miranda ;
We obtain the L. C. M of 7 and 9, the. Divide by the amount she spends per visit ;
Multiples of :
7 = 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77
9 = 9, 18, 27, 36, 45, 54, 63, 72, 81
Hence, lowest common multiple of 7 and 9 is 63 ;
Hence, least possible. Number of visits by Miranda is ; 63 / 7 = 9 visits

when you graph the equations, they are parallel. as you know, solutions are the point where the lines meet. if they are parallel, it's not possible for the lines to intersect.
Answer and Step-by-step explanation:
Lets solve each one and see which has solutions and which one doesn't have a solution.
__________________________________________________________
A) x + y = -6
x + y = 12
Solve for y for one of the equations, then plug it into the other equation.
y = -6 - x
x + (-6 - x) = 12 = -6 = 12 No Solution

Answer:
Hint: f(x) = y
Step-by-step explanation:
The best way to approach these type of questions is to first substitute the x in the equation with one of the numbers from the table that contains x and y. For example, number 5, f(x) = 8x - 5. One of the numbers states x as 0, meaning I can substitute 0 into the equation as x => f(x) = 8(0) - 5. After that I solve to find f(x), and fill out the slot next to 0. This can be repeated for all blank slots of y. Hope it helped. :)

10+4x = 5(x−6)+ 33
solve for x
Answer:
X=7
Step-by-step explanation:
10+4x=5(x-6)+33
1. Distribute the 5 to both the x and the 6
10+4x=5x-30+33
2. Subtract 4x from 5x ( should be left with 1x but just write x)
10=x-30+33
3. add 30 to both sides (whole number on the left, x on the right)
40=x+33
4. Subtract 33 on both sides
7=x (flip it around)
x=7
A car moving at a constant speed passed a timing device at t=0. After 7 seconds, the car has traveled 567 ft. Write a linear function rule to model the distance in feet d the car has traveled any number of seconds t after passing the timing device.
Answer:
The required equation is:
d = 81tf(t) = 81tStep-by-step explanation:
We know that
distance = rate × t
Given that a car moving at a constant speed passed a timing device at t=0.
In other words, at t = 0 second, d = 0 ft.
After 7 seconds, the car has traveled 567 ft.
In other words, at t = 7 seconds, d = 567 ft
Thus, there are two points
(0, 0)
(7, 567)
Finding the slope between (0, 0) and (7, 567)
Using the formula
Slope = Rate of change = [y₂-y₁] / [x₂-x₁]
= [567 - 0] / [7-0]
= 567 / 7
= 81 ft/second
Given that the car is moving at constant speed. So, we dont't have any other factor or term to consider
Thus, the required equation is:
distance = rate × t
d = 81 × t
d = 81t
or
f(t) = 81t
VERIFICATION
Given the equation
d = 81 × t
Put t = 0 to find the disatance in 1 sec
d = 81 × (0) = 0 ft
Put t = 7 to find the distance in 7 seconds
d = 81 × (7) = 567 ft

Answer:
8
Step-by-step explanation:
First, solve the left side by adding/subtracting all the x's. 5x + 4x - 6x = (5+4-6)x = (9-6)x = 3x
Then if 3x=24, x must be 8.

By what numbers would you need to multiply the two equations in order to eliminate y? By what
numbers would you need to multiply the two equations in order to eliminate x instead? Drag and drop
the correct numbers and words into the boxes to complete the explanation.
You could multiply the first equation by
and the second equation by

then
the resulting equations to eliminate y. You might choose to eliminate x instead. To
do this, you would multiply the first equation by and the second equation by
and then

If you want to eliminate x than multiply equation 1 by 4 and equation 2 by 3 and subtract them or,
If you want to eliminate y than mutiply equation 1 by 8 and equation 2 by 11 and subtract them.
