y = -6x - 16
-2x + 4y = -2
Step 2: Solve for x
Substitution
Substitute in y: -2x + 4(-6x - 16) = -2Distribute 4: -2x - 24x - 64 = -2Combine like terms: -26x - 64 = -2[Addition Property of Equality] Add 64 on both sides: -26x = 62[Division Property of Equality] Divide -26 on both sides: x = -31/13Step 3: Solve for y
Define original equation: y = -6x - 16Substitute in x: y = -6(-31/13) - 16Multiply: y = 186/13 - 16Subtract: y = -22/13PLEASE SHOW YOUR WORK.
Shawn designs a rectangular garden as shown below. He will design both rock sections to have the same width (x).
The area in, square feet, of Shawn’s garden is found be calculating 15(2x + 7). Shawn incorrectly says the area can also be found using the expression 30x + 7.
Describe the error in Shawn’s expression. As part of your explanation, find the difference, in square feet, between the actual area of Shawn’s garden and the area found using his expression.
Answer:
a) Shawn's error was that he Multiplied 15 by 2x only. He didn't Multiply 15 by 7
b) The difference, in square feet, between the actual area of Shawn’s garden and the area found using his expression is given as
98 square feet
Step-by-step explanation:
The area in, square feet, of Shawn’s garden is found be calculating 15(2x + 7). Shawn incorrectly says the area can also be found using the expression 30x + 7.
The correct area =
15(2x + 7).
= 30x + 105 square feet
The error in Shawn’s expression is
= 15(2x + 7)
= 30x + 7 square feet
Shawn's error was that he Multiplied 15 by 2x only. He didn't Multiply 15 by 7
The difference, in square feet, between the actual area of Shawn’s garden and the area found using his expression is given as
30x + 105 square feet - 30x + 7 square feet
= 30x + 105 - (30x + 7)
= 30x - 30x + 105 - 7
= 98 square feet
Write an equation of the line that passes through the pair of points. (−4, −2), (4, 0)
Answer:
y = 1/4x-1
Step-by-step explanation:
Ok first, you need to find the slope:
0+2 = 2=1
4+4 = 8=4
Slope: 1/4
y=1/4x+b
Now you need to find the y intercept which is b. For that you can take a coordinate pair and substitute it in the equation to find b.
I will use (4,0)
0=1/4 X 4 + b
0=x+b
minus x on both sides. x=1
-1=b
An equation of the line that passes through the pair of points
(- 4, - 2), (4, 0) is y + 2 = (1/4)(x + 4).
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, A line that passes through the pair of points. (−4, −2), (4, 0).
We also know slope(m) = (y₂ - y₁)/(x₂ - x₁) = (0 + 2)/(4 + 4) = 1/4.
So, the equation of a line in point-slope form is y - y₁ = m(x - x₁).
∴ y + 2 = (1/4)(x + 4).

Find the slope of the following graphs.
A. 2/3
B. 3/2
C. 3
D. - 2/3
Answer:
Answer is A
Step-by-step explanation:
The slope of the shown line passing through points (3,2) and (0,0) is 2/3. The answer is option A.
Given the points (3,2) and (0,0), we can calculate the change in y and change in x as follows:
Change in y = 2 - 0 = 2
Change in x = 3 - 0 = 3
Now, we can substitute these values into the slope formula:
Slope = (change in y)/(change in x) = 2/3
Here, the line has a positive slope, indicating that as x increases by 1, y increases by 2/3.
This means that the line is ascending from left to right, sloping upwards.
Therefore, the slope of the line passing through points (3,2) and (0,0) is 2/3.
Hence, the answer is option A.

f(x) = 2x + c
g(x) = cx + 7
fg(x) = 4x + d
C and d are constants.
Work out the value of d.
May someone help me pleaseeee
Answer:
c=2, d=16
Step-by-step explanation:
The value of c is 2 and value of d is 16 when f(x) = 2x + c, g(x) = cx + 7 and fg(x) = 4x + d
What is a function?A relation is a function if it has only One y-value for each x-value.
Given,
f(x) = 2x + c...(1)
g(x) = cx + 7..(2)
fg(x) = 4x + d..(3)
We need to find the values of c and d
fg(x) = 2(cx+7) + c
Apply distributive property
fg(x) =2cx+14+c...*
Now compare * with equation 3
2cx=4x
2c=4
Divide both sides by 2
c=2
and 14+c=d
Substitute c in above equation
14+2=d
d=16
Hence, the value of c is 2 and value of d is 16 when f(x) = 2x + c, g(x) = cx + 7 and fg(x) = 4x + d

We are given that :
5 miles ------> 8 km
we divide both sides by 5 to get the unit rate:
1 miles ------> 8/5 km
Therefore:
27.5 miles -----> 27.5 miles x (8/5) = 44 km
Evaluate p(x) = -3 + 4x when x = -2, 0, & 5
p(-2) =
p(0) =
p(5) =
Answer:
p(-2) = -11
p(0) = -3
p(5) = 17
Step-by-step explanation:
Step(i):-
Given that the polynomial function p(x) = -3 +4x ..(i)
Given x =-2 , 0 and 5
put x =-2 in equation (i)
p(-2) = -3 +4(-2)
= -3 -8
p(-2) = -11
Step(ii):-
put x =0 in equation (i)
p(0) = -3 +4(0)
= -3 +0
p(0) = -3
Step(iii):-
put x = 5 in equation (i)
p(5) = -3 +4(5)
= -3 +20
p(5) = 17

The graph of p = 400 and the graph of p = 50s - 200 intersect at the point (12,400). If the equation p = 50s - 200 represents the profit, p, based on s sales, what does the intersection best represent? Show work.
Answer:
This shows that the profit for 12 sales is 400
Step-by-step explanation:
If both graphs intersects then;
p = p
400 = 50s - 200
50s = 400+200
50s = 600
s = 600/50
s = 12
Substitute s =12 into p = 50s-200
p = 50(12) - 200
p = 600-200
p = 400
Hence the intersection (s, p) is (12, 400)
This shows that the profit for 12 sales is 400
