2. Solve the system of equations using the substitution method.
y = 10 - 4x
2x + 3y = 20
Please show how you got it
Answer:
x = 1
Step-by-step explanation:
2x + 3y = 20
2x + 3(10-4x) = 20
2x + 30 - 12x = 20
combine like terms
-10x + 30 = 20
-30 -30
-10x = -10
divide both sides by -10
x = 1
Hope this Helps!!!
The solution of the linear equations y = 10 - 4x and 2x + 3y = 20 will be (1, 6).
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equations are given below.
y = 10 - 4x ...1
2x + 3y = 20 ...2
Substitute equation 1 in equation 2, then we have
2x + 3(10 - 4x) = 20
2x + 30 - 12x = 20
10x = 10
x = 1
Then the value of the variable 'y' will be given as,
y = 10 - 4(1)
y = 10 - 4
y = 6
The solution of the linear equations y = 10 - 4x and 2x + 3y = 20 will be (1, 6).

What is the solution to the equation 36 – 5x = 5 – 6(x - 4) ?
68bpoints
Step-by-step explanation:
36-5x=5-6(x-4)36-5x=5-6x+24
-5x+6x=24+5-36
x=29-36
x=-7
Answer:
x = -7
Explanation:
36 − 5x = 5 − 6(x − 4)
[ Simplify both sides of the equation ]
36 − 5x = 5 − 6(x − 4)
36 + −5x = 5 + (−6)(x) + (−6)(−4) [ Distribute ]
36 + −5x = 5 + −6x + 24
−5x + 36 = (−6x) + (5 + 24) [ Combine Like Terms ]
−5x + 36 = −6x + 29
−5x + 36 = −6x + 29
[ Step 2: Add 6x to both sides ]
−5x + 36 + 6x = −6x + 29 + 6x
x + 36 = 29
[ Step 3: Subtract 36 from both sides ]
x + 36 − 36 = 29 − 36
x = −7

55% of what number is 330? pls help meee
Answer:
600
Step-by-step explanation:
Assume x=target number
55%(x)=300
55%=0.55
0.55x=300
x=300/0.55
x=600
Answer
600
Step-by-step explanation:
Here is the formula/format:
Part %
------ = --------
Whole 100
We are trying to find the "whole" in this case, so I did:
330 55
------- = ------- (this says that 55% of the number we are looking for is 330)
x 100
Then, I cross multiplied and got: 55x= 33,000
From there, I divided 33,000 by 55 (inverse operations) to get x = 600.

Answer:
(3, 4)
Step-by-step explanation:
The ordered pairs comprise a function because no x-value is repeated. If you want the list to be not-a-function, then one of the x-values must be repeated.
The x-values given in the original function list are -2, 3, 7, 9. The only one of these that is an x-value in an answer choice is 3, in the pair (3, 4).
Adding (3, 4) will make the relation not a function.

Kelly has 15 blue bracelets and 12 green bracelets What is the ratio of Kelly's blue bracelets to green bracelets?
Answer:
1. $1.15 a jar, 2. 11% 3. 15 to 12
Step-by-step explanation:
Answer:
15 is 20% of 75. And 15:12.
Step-by-step explanation:
Emily had 75 buttons. She gave 15 buttons to Jake. What percent of the buttons did Emily give to Jake?
She gave 15 out of her 75 buttons, so we have to figure out what percentage of buttons did she give to Jake. 20 times 5 = 100 and 5 times 15 = 75, so that is how we end up with the answer- 15 is 20% of 75.
Kelly has 15 blue bracelets and 12 green bracelets What is the ratio of Kelly's blue bracelets to green bracelets?
When you are doing ratios, all you have to do is put the two numbers in ratio form, such as 15:12.

The diagonals of a parallelogram meet at the point (0, 1). One vertex of the parallelogram is located at (1, 3), and a second vertex is located at (2, 0). Find the locations of the remaining vertices, and determine the most specific classification of this parallelogram.
The locations of the remaining vertices are at (−2, 1) and (−1, −2). The most specific classification of this parallelogram is a square.
The locations of the remaining vertices are at (−2, 1) and (−1, −2). The most specific classification of this parallelogram is a rhombus.
The locations of the remaining vertices are at (−2, 2) and (−1, −1). The most specific classification of this parallelogram is a square.
The locations of the remaining vertices are at (−2, 2) and (−1, −1). The most specific classification of this parallelogram is a rectangle.
Answer:
The answer is C
Step-by-step explanation:
The locations of the remaining vertices are at (−2, 2) and (−1, −1). The most specific classification of this parallelogram is a rectangle.
The correct option is (D).
What are Coordinates?Coordinates are a set of values which helps to show the exact position of a point in the coordinate plane.
Given:
Diagonal vertex = (0,1 )
One vertex of the parallelogram is located at (1, 3)
and, second vertex is located at (2, 0).
Now, Going from (0,1) to (2,4) is 2 units in x- axis, 3 units in y- axis.
So, the vertex opposite (2,4) would be -2 units in x- axis, -3 units in y- axis.
= (0,1) + (-2,-3)
=(0-2, 1-3)
= (-2,-2)
and, Going from (0,1) to (3,1) is 3 units in x- axis, 0 units in y- axis.
So the vertex opposite (3,1) would be -3 units in x- axis, 0 units in y- axis.
= (0,1) + (-3,0)
= (-3,1)
Hence, The locations of the remaining vertices are at (−2, 2) and (-3, 1). The most specific classification of this parallelogram is a rectangle.

Can you find the slope-intercept equation of each line and type the correct code? Please remember to type in ALL CAPS with no spaces.
Answer:
The answer for the code is CGIA
Step-by-step explanation:
The slope- intercept of each line is
First line,y= x+ 2
Second line,y = 2x +2
Third line,y= -x +1
Fourth line,y= -2x - 2
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
First line,
slope intercept form
(y - 3)= 1(x-1)
y= x+ 2
Second line,
slope intercept form
(y - 2)= 2(x-0)
y = 2x +2
Third line,
slope intercept form
(y + 2)= (-1)(x - 3)
y= -x +1
Fourth line,
slope intercept form
(y + 2 )= -2(x-0)
y= -2x - 2
