Answer:
The slope of the line= 2/3
Step-by-step explanation:
(2, 2)=(x, y) and (5, 4)=(`x, `y)
The formula for finding slope= `y-y/`x-x
4-2/5-2
2/3
Therefore, the slope=2/3
Look at this system of equations.
-3x+3y=12
y=x+4
The solution set of this system is best explained by which of these statements?
A
The graphs of the equations are parallel lines because they have the same slope but different y-intercepts. The system has no solution.
B
The graphs of the equations are the same line because the equations have the same slope and the same y-intercept. The system has infinitely many solutions.
C
The graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. The system has exactly one solution.
D
The graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. The system has exactly one solution.
Answer:
D. The graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. The system has exactly one solution.

If Holly gets 14 % off a shirt , what percent of the original price will still pay
Answer:
Holly will still pay 86% of the original price.
Step-by-step explanation:
Given
Holly gets 14% off a shirt, soDiscount = 14%To determine
What percent of the original price will still pay.
All we need is to subtract the percentage of discount from 100.
i.e.
100 - Discount = 100 - 14 = 86%
The amount left over would be what remains of the original price after Holly gets 14 % off a shirt.
Thus, Holly will still pay 86% of the original price.

Solve the inequality for x.
x-c/d > y (for d > 0)
The solution for x of the inequality x-c/d > y (for d > 0) is x > d * y + c.
Here,
To solve the inequality for x, we'll isolate x on one side of the inequality:
Given inequality: (x - c) / d > y
First, we'll multiply both sides of the inequality by d to get rid of the fraction.
Remember that since d > 0, we don't need to reverse the inequality:
d * [(x - c) / d] > d * y
Next, the d on the left side cancels out, and we have:
x - c > d * y
Now, to isolate x, we'll add c to both sides of the inequality:
x - c + c > d * y + c
x > d * y + c
So the solution for x is x > d * y + c.

A rectangle has perimeter 200 feet.
1. Let L represent the length of the rectangle. Write an equation for the width W in terms of L.
2. Write a function A(L) that represents the area of the rectangle with length L.
Answer:1. (200-2L)/2 2.L x (200-2L)/2=A
Step-by-step explanation:
Answer:
Part 1)
[tex]W=100-L[/tex]
Part 2)
[tex]A(L)=L(100-L)[/tex]
Step-by-step[tex]W = 100-L[/tex] explanation:
We are given a rectangle with a perimeter of 200 feet.
Part 1)
The formula for perimeter for a rectangle is:
[tex]200=2(L+W)[/tex]
We can divide both sides by 2:
[tex]100=L+W[/tex]
And subtracting L from both sides yields:
[tex]W=100-L[/tex]
Part 2)
The area of a rectangle is given by:
[tex]A(L)=LW[/tex]
Since we solved for W earlier:
[tex]A(L)=L(100-L)[/tex]

Emilia and Sydney went out to dinner. The bill came to $48. They want to leave a 20% tip and
split the bill. How much do they each pay?
$9.60
$28.80
$57.60
$68.00
Answer:
Option B is correct.
Step-by-step explanation:
Total bill = $48
Tip = 20%
Amount of tip = 20% of 48
Amount = [tex]\frac{20}{100}*48[/tex]
Amount = 0.2 * 48
Amount = $9.60
Total bill with tip = 48 + 9.60 = $57.60
Dividing by 2 as they are spliting the bill.
Each pays = [tex]\frac{57.60}{2}=28.80[/tex]
Therefore,
Option B is correct.

The length of the side k in the given triangle is 1,373.9 cm.
What is cosine law?The law of Cosines, also known as Cosine Rule or Cosine Formula basically relates the length of the triangle to the cosines of one of its angles.
Given that, in ΔKLM, l = 820 cm, m = 560 cm and ∠K=169°, we need to find the length of side k,
Using the cosine law,
k² = l²+m² - lmCos169°
= 820²+560²-(820)(560)cos169°
= 1,373.9
Hence, the length of the side k in the given triangle is 1,373.9 cm.

5 divided 9/10 in fractions forms
Answer: 5 5/9
Step-by-step explanation:
cause that’s the answer
5 divided by 9/10, in fraction form, is 50/9.
To divide 5 by 9/10, we can convert the whole number 5 into a fraction with a denominator of 1.
5 can be expressed as 5/1.
We can rewrite the division problem as a multiplication problem by taking the reciprocal (flipping the numerator and denominator) of the divisor:
5/1 ÷ 9/10
= 5/1 × 10/9
Multiply the numerators together and the denominators together:
(5×10) / (1 × 9) = 50/9
Therefore, 5 divided by 9/10, in fraction form, is 50/9.
