Step-by-step explanation:
The perimeter of a rectangle is 86. The length of the rectangle is one more than twice the width. Determine the length and width of the rectangle.
There are two equation of the system
(1) The perimeter
2(w + l) = p
2(w + l) = 86
(2) The length and the width
2w = l + 2
From the second equation
2w = l + 2
l + 2 = 2w
l = 2w - 2
Subtitute l with 2w - 2 in the first equation to find the width
2(w + l) = 86
2(w + 2w - 2) = 86
2(3w - 2) = 86
6w - 4 = 86
6w = 90
w = 15
Now, find the length by subtituting w with 15
l = 2w - 2
l = 2(15) - 2
l = 30 - 2
l = 28
The dimension of the rectangle
length = 28 cm
width = 15 cm

Answer:
Since the shape was formerly a square,ofarea 100in²
Then,Area of square=side×side
100in²=side²
side=√100in²
side=10 inches
Perimeter of the shape=10+10+7+6+5
=38inches
Now a length of 3inches is cut off from the upper horizontal side and a length of 4in is also cut off from the right vertical side.
So now we can say a triangle of base 4in and height 3in is cut off from the square.
Area of cut off triangle=½base×height
=½×4×3=0.5×12
=6 inches ²
So the Area of the shape=Area of square-Area of triangle
=100-6=94inches²

Help me please and thank you :)
Answer:
A. 74 cm
Step-by-step explanation:
First, we break the rhombus down into similar shapes,
The area of 2 triangles = The area of a square
So we take the triangle from the left and combine it with the triangle on the right, it should make a rectangle, Then calculate the area of the rectangle,
10 multiplied by 5 =50
Thats the area of rectangle 1
Rectangle 2
3 multiplied by 6 = 18
Triangle
4 times 3 divided by 2 = 6
Thus
6 + 18 + 50 = 74

to plot the point (-3,6), start at the origin and move three places down and six places right.
(theres no graph)
Answer: 3,3
Step-by-step explanation: the -3 is the x and 6 is the y so if u move 3 down on the y, it’s 3 and if you do 6 right, split the six, -3 plus 3 is 0 plus the remaining 3 is 3

Step-by-step explanation:
Fine two integers that have a sum of -17 and a product of 52. What are the integers?
Answer:
{4, 13}
Step-by-step explanation:
Represent the integers by I and J. Then I + J = -17 and I*J = 52.
Let's solve this system using substitution. Solve the first equation for I as follows:
I + J = -17 becomes I = -J - 17
Substitute -J -17 for I in the second equation:
(-J - 17)*J = 52
Performing the indicated multiplication, we get:
-J^2 - 17J - 52 = 0
Let's solve this using the quadratic formula. The quadratic coefficients here are {-1, -17, -52}, and so the discriminant, b^2 - 4ac, is
(-17)^2 - 4(-1)(-52), or 289 - 208, or 81. This result is positive, so we know that the quadratic equation has two real, unequal roots. They are:
17 ± √81 17 ± 9
J = --------------- = ---------------
2(-1) -2
Evaluating this last result, we get J = (17 + 9)/2, or J = 13, and
J = (17 - 9)/2 = 8/2, or J = 4

A pair of sneakers that cost $90 last year has now been marked up 25%. Mariel has a coupon that is going to take 10% off the price of the shoes. Is the price that she will pay equivalent to a 15% markup of the original cost of the shoes? Show your work.
Answer:
Your answer is no.
Step-by-step explanation:
The answer is no because when using the coupon she's only getting 10% off of the price AFTER 25% is added.
10% off of the original price is: $81.00
10% off of the new price is: $101.25

• The y-intercept represents a starting salary of $ ? for a new employee. • The slope represents an additional $ ? in salary for each additional year of employment. • If the starting salary for a new employee is changed to $35,000 and the yearly salary increase is unchanged, the new equation would be y = ? x + ? . • If the yearly salary increase is changed to $ ? , the new equation would be y = ? x + ? .
Answer:
Can you show the graph please?
Step-by-step explanation:
Answer:
300
Step-by-step explanation:
If the yearly salary increase is changed to $ ? , the new equation would be y = ? x + ?.
Let $e for new empolyee.
Let $s for slope for salary.
We know if the starting salary for a new employee is changed to $35,000 and the yearly salary increase is unchanged, the new equation would be y = ?
y = ? the question mark will represent x.
Because $35,000 is the only number, that will be our main goal.
So $35 in shorten, added 25, 20. Which is 45.
With that we do +200 - 45. 155.
So 45+255=300
