of a yard to a friend. How much does she have left?
Answer:
[tex] \frac{9}{10} - \frac{7}{20} \\ \frac{9 \times 2}{10 \times 2} - \frac{7}{20} \\ \frac{18}{20} - \frac{7}{20} \\ \frac{18 - 7}{20} \\ \frac{11}{20} \\ 0.55[/tex]
Step-by-step explanation:
rabeeca has 0.55 ribbon left.
Answer:
11/20
Step-by-step explanation:
first you need to multiple 9/10 by 2/2 to get 18/20 and then 7/20 multipled by 1/1 and for the last step do 18-7 to get 11 so therefore the answer is 11/20

Slope is 1 and (-2, -1) is on the line.
Answer:
You can’t find the slope of a line if only given one point. If you had a visual representation of the line such as a graph or a table you could find a second point and then use the formula for slope, y = (y2-y1) / (x2-x1).
Imagine a single point on the xy graph. You could take a random point elsewhere from an infinite number of points and would be able to draw a line and find the slope. This means there could be an infinite number of different slopes for one point. One point on an unknown line is not enough information to determine the slope of its line without a graph or a table.

2) the coordinates of the vertices of a triangle JKL are J (4,8) K (8,8) L (4,2). Find the coordinates of the vertices of the image after a dilation by K = 0.25
• J (2,1) K (2,2) L (1,2)

When given the building layout of store a 2500ft2, store b 625ft2, store c 625ft2, store d 2500ft2, what portion of the $7500 maintenance fee should be apportioned to store c?
9514 1404 393
Answer:
$750
Step-by-step explanation:
The total store area in the building is ...
2500 +625 +625 +2500 = 6250 . . . . square feet.
Then the fraction that can be allocated to store C is ...
(625 ft²)/(6250 ft²) = 0.1
The maintenance fee allocated to store C should be ...
0.1 × $7500 = $750
Graph the given equation by evaluating integer values of x from -2 to 2 and plotting the resulting points.
y = -2x - 4
Graphs are created from functions and equations.
See attachment for the graph of [tex]\mathbf{y = -2x - 4}[/tex]
The equation is given as:
[tex]\mathbf{y = -2x - 4}[/tex]
When x = -2, we have:
[tex]\mathbf{y = -2(-2) - 4 = 0}[/tex]
When x = -1, we have:
[tex]\mathbf{y = -2(-1) - 4 = -2}[/tex]
When x = 0, we have:
[tex]\mathbf{y = -2(0) - 4 = -4}[/tex]
When x = 1, we have:
[tex]\mathbf{y = -2(1) - 4 = -6}[/tex]
When x = 2, we have:
[tex]\mathbf{y = -2(2) - 4 = -8}[/tex]
So, the points on the graph are:
[tex]\mathbf{(x,y) = (-2,0)(-1,-2)(0,-4)(1,-6)(2,-8)}[/tex]
See attachment for the graph of [tex]\mathbf{y = -2x - 4}[/tex]

Bank account A starts with $5,000 and grows by $1,000 each week. Bank account B starts with $1 and doubles each week.
1.which account has more money after one week?After two weeks?
Answer:
AStep-by-step explanation:
If bank A keeps adding on 1,000 and bank B is only doubling by 2 then A is much greater than B.
The account that has more money after one week is account A.
The account that has more money after two weeks is account A
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Account A:
Balance = $5000
Each week increase = $1000
Amount after one week.
= 5000 + 1000
= 6000
Amount after 2 weeks.
= 6000 + 1000
= 7000
Account B:
Balance = $1
Each week's increase = doubles the amount
Amount after 1 week.
= $2
Amount after 2 weeks.
= $4
Thus,
Account A has more money after one week.
Account A has more money after two weeks.

What is the equation of a line that passes trough (6,-1) and is parallel to the line that has a slope of -2/3?
Answer:
y=-2/3x+3
Step-by-step explanation:
First, identify the slope you need for your equation. The keyword here is "parallel" so the slope you need is the same as the given slope (-2/3).
Next, use the ordered pair (6,-1); it's on the line that you need to find the equation for. Using slope-intercept form (y=mx+b), plug the -1 in for y, plug the 6 in for x, and plug in your slope of -2/3 for m. Solve for b, your y-intercept. You should get 3.
You have your slope and y-intercept now. Create your equation:
y=-2/3x+3.
