The slope of the given line with points (0, -3) and (-2, 5) is -4.
What is the slope?The slope is the rate of change of the y-axis with respect to the x-axis. We can also think of slope as the rise over run. The slope of a line also describes the amount of angle a line forms from the positive x-axis.
From the given graph we can determine two points when x = 0 , y = -3 and when x = -2 , y = 5.
∴ The points of the given line are (0, -3) and (-2, 5).
We know the slope of a line is rise over run which is (y₂ - y₁)/(x₂ -x₁).
Therefore the slope of the given line is,
= (5 + 3)/(-2 - 0).

The two consecutive even integers whose product is 440 are 20 and 22. When considered as positive and negative, they are +20 and -20, +22 and -22, respectively.
Explanation:To find the two consecutive even integers whose product is 440, we need to employ some algebraic reasoning. Let's denote the first of the two consecutive even integers as x.
Given that even integers follow a pattern of +2, we can denote the next consecutive even integer as x + 2.
Hence, we're solving for the equation x * (x + 2) = 440. Solving this equation will give us our consecutive even integers, which are 20 and 22. In terms of positive and negative integers, they would be represented as +20 and -20, +22 and -22, respectively.

Each side of rhombus 7 cm find the perimeter of a rhombus
Answer:
P = 28cm
Step-by-step explanation:
First, all four sides of a rhombus are congruent, meaning that if we find one side, we can simply multiply by four to find the perimeter. Second, the diagonals of a rhombus are perpendicular bisectors of each other, thus giving us four right triangles and splitting each diagonal in half.

Elliott has some yarn that she wants to use to make hats and scarves. Each hat uses 0.2, point, 2 kilograms of yarn and each scarf uses 0.1, point, 1 kilograms of yarn. Elliott wants to use twice as much yarn for scarves as for hats, and she wants to make a total of 20 items.
Answer:
Elliot will make 4 hats and 16 scarves
Step-by-step explanation:
Let x be the number of hats and y be the number of scarves Elliot will make.
Elliott wants to make a total of 20 items, then
x + y = 20
Each hat uses 0.2 kilograms of yarn, so x hats use 0.2x kilograms of yarn and each scarf uses 0.1 kilogram of yarn, then y scarves use 0.1y kilograms of yarn. Elliott wants to use twice as much yarn for scarves as for hats, then
0.1y = 2(0.2x)
Thus,
0.1y = 0.4x
y = 4x
Substitute it into the first equation:
x + 4x = 20
5x = 20
x = 4
y = 20 - 4
y = 16
Hence, Elliot will make 4 hats and 16 scarves

Step-by-step explanation:
Kyle works at a donut factory, where a 10-oz cup of coffee costs 95cents, a 14-oz cup costs $1.15, and a 20-oz cup costs $1.50. During one busy period, Kyle served 30 cups of coffee, using 464 ounces of coffee, while collecting a total of $37.20. How many cups of each size did Kyle fill?
Answer:
4, 16 and 10
Step-by-step explanation:
Here we would like to work with a system of 3 equations, we need ti find them. Lets call s the 10oz coffees, m the 14oz and l the 20oz.
As Kyle sold $37.2 selling 3 different types of coffee at their respective prices we can say:
revenue = s*0.95 + m*1.15 + l*1.5 = 37.2 [equation 1]
And as he sold 30 cups:
s + m + l = 30 [equation 2]
And as the total volume of coffee is 464 oz:
s*10 + m*14 + l*20 = 464 [equation 3]
So, we have a system of 3 equations with three unknowns s, m and l.
Take the eq 2 and subtract m and l in both sides:
s = 30 - m - l
Now, take it and replace in the other 2:
(30 - m - l)*10 + 14m + 20l = 464 [eq 3]
0.95(30 - m - l) + 1.15m + 1.5l = 37.2 [eq 1]
Working with equation 3:
300 -10m -10l + 14m + 20l = 464
300 + 4m + 10l = 464
4m + 10l = 164 [equation 3']
Now with eq 1:
0.95(30 - m - l) + 1.15m + 1.5l = 37.2
28.5 - 0.95m - 0.95l + 1.15m + 1.5 l = 37.2
28.5 + 0.2m + 0.55l = 37.2
0.2m + 0.55l = 8.7 [equaiton 1']
Now we passed to a 2-equation system with eq 1' and eq 3'.
Take eq 3' and subtract 4m in both sides:
10l = 164 - 4m
Now divide by 10 in both sides
l = [164 - 4m]/10
Now, with this value for l replace in eq 1':
0.2m + 0.55 ( [164 - 4m]/10) = 8.7
0.2m + 0.055 (164 - 4m) = 8.7
0.2m + 9.02 - 0.22m = 8.7
- 0.02m = -0.32
m = -0.32/-0.02
m = 16 ----> 16 14oz coffees
Now replace m=16 in eq 1' or 3' to find l:
4m +10l = 164
64 + 10l = 164
10l = 100
l = 10 ----> 10 20oz coffees
So, finally we replace l=10 and m=16 in equaiton 2:
s + m + l = 30
s + 16 +10 = 30
s = 30 - 26
s = 4
So, Kyle filled 4 10oz coffes, 16 14oz coffees and 10 20oz coffees.

A runner runs 8 miles in 92 minutes what is the runner’s unit rate?
Answer:
The runner's unit rate is 0.09 miles/minute.
Step-by-step explanation:
Given:
Distance cover by runner = 8 miles and the time taken = 92 minutes.
Now, to calculate the runner's unit rate.
We put the formula to get the unit rate:
Velocity = distance/time
[tex]v=\frac{d}{t}[/tex]
[tex]v=\frac{8}{92}[/tex]
[tex]v=0.0869[/tex]
v = 0.09 miles/minute (approximately)
Therefore, the runner's unit rate is 0.09 miles/minute.
Final answer:
To find the runner's unit rate, divide the total miles (8) by the total minutes (92), resulting in a rate of 0.08695652 miles per minute or 5.217 miles per hour when converted.
Explanation:
The question is asking to find the unit rate of a runner who runs 8 miles in 92 minutes. To find the unit rate, we need to calculate how many miles the runner can run in one minute. This involves dividing the total miles run by the total minutes taken.
Calculation:
Unit Rate = Total Miles / Total Minutes = 8 miles / 92 minutes = 0.08695652 miles per minute.
For practical purposes and better understanding, it might be useful to convert this unit rate into miles per hour. Since there are 60 minutes in an hour, we simply multiply the unit rate per minute by 60.
Miles per hour = 0.08695652 miles/minute * 60 minutes/hour = 5.217 miles per hour.
Therefore, the runner's unit rate is 0.08695652 miles per minute, or equivalently, 5.217 miles per hour.

Which of the following is a solution to this inequality? y greater than one half times x plus 2 (1, 4) (−1, 1) (2, 3) (0, 2)
Answer:
(1, 4)
Step-by-step explanation:
Lets show first the inequality. Putting in numbers what greater than one half times x plus 2 means is:
y > (1/2)x + 2
The procedure is simple: take the points and replace them in the inequality to see which verifies.
(1, 4):
4 > (1/2)*1 + 2
4> 1/2+ 2
4 > 1/2 + 4/2
4> 5/2
8/2> 5/2 ---> I verifies!!!
(-1, 1)
1 > (1/2)(-1) + 2
1> -1/2 + 2
1 > -1/2 + 4/2
1 > 3/2 ---> Not verify!!
(2, 3):
2 > (1/2)*2 + 2
2 > 1 + 2
2 > 3 ---> Not verify!!!
(0, 2)
2 > (1/2)*0 + 2
2 > 2 ---> Not verify!!!
So, the only pair that verifies is (1, 4)
The quadrilateral shown is a parallelogram. If m∠ADC = 125° and m∠1 = 30°, what is m∠2? A) 15° B) 25° C) 35° D) 55°
Answer:
B) 25°
Step-by-step explanation:
Assuming the quadrilateral is the one shown in the picture attached, then a triangle ADC is form, where m∠ADC = 125° and m∠1 = 30°. The addition of the three angles of a triangle is equal to 180°, so:
m∠ADC + m∠1 + m∠2 = 180°
Replacing with the known values and isolating m∠2 we get:
125° + 30° + m∠2 = 180°
m∠2 = 180° - 125° - 30°
m∠2 = 25°
Answer:
it is 25 degrees

a rectangular pasture has a perimeter of 1000 feet. the pastures length is 300 feet more than its width.
whats the area of the pasture?
Answer:
40,000 ft
Step-by-step explanation:
The area of a rectangle is weight*length, and the perimeter is the sum og the four sides, which are 2 lengths sides ans 2 width sides, so:
area = w*l
perimeter = 2w + 2l
If the perimeter is 1000 ft:
2w + 2l = 1000
Also, the length is 300 ft more than width, so:
l = 300 +w
So, our system is:
2w + 2l = 1000 (equation 1)
l =300 + w (equation 2)
Son, we can solve it by replacing equation 2 in equation 1:
2w + 2(300 +w) = 2w + 600 + 2w = 4w + 600 = 1000
Now, subtract 600 in both sides:
4w + 600 - 600 = 1000 - 600
4w = 400
Divide both sides by 4:
4w/4 = 400/4
w = 100
Lets replace this w value in equation 2 to find l:
l = 300 + 100 = 400, so l=400
Finally we can find the area using the area formula:
area = 400*100 = 40,000 ft2
So, the area is 40,000 ft2
Final answer:
The area of the pasture is found by setting up and solving a linear system (1000 = 2w + 2(w + 300)); the dimensions of the rectangle are found to be 100 feet in width and 400 feet in length. The area is then calculated by multiplying the width by the length, yielding an area of 40,000 square feet.
Explanation:
To solve the problem, we need to establish a system of linear equations to find the dimensions of the pasture. Given that the perimeter of a rectangle is 2 times the width plus 2 times the length (P = 2w + 2l), and the length is 300 feet more than its width (l = w + 300), we can set up the following equations:
P = 2w + 2l
l = w + 300
Since we know the perimeter is 1000 feet, we substitute this value into the first equation:
1000 = 2w + 2(w + 300)
1000 = 2w + 2w + 600
1000 = 4w + 600
400 = 4w
w = 100 feet
Once we have the width, we can substitute this into the second equation to find the length (l):
l = 100 + 300
l = 400 feet
To find the area of the pasture, we multiply the width by the length:
Area = width × length = 100 feet × 400 feet = 40,000 square feet
The area of the pasture is 40,000 square feet.

Hope this helps!
Answer: x = 3
Step-by-step explanation: To solve for x in the equation you see here, our goal is to get x by itself.
Our first step will be to isolate the term containing x which in this case is 2x. To isolate 2x, we have to get rid of the 3 by subtracting 3 from both sides of the equation.
On the left, the 3's cancel each other out and we are left with 2x. On the right, 9 - 3 simplifies to 6 and we are left with 2x = 6 which is a one step equation.
To get x by itself, since it's being multiplied by 2, we just divide both sides of the equation by 2. On the left, the 2's cancel and we are left with x. On the right, 6 over 2 simplifies to 3.
Therefore, our answer is x = 3.

Answer:
3. The superhero is afraid of heights.
"The superhero is afraid of heights." is independent clause because the sentence contains a subject and verb and it's a complete sentence.
Step-by-step explanation:
An independent clause is a group of words that contains a subject and verb and expresses a complete thought. An independent clause is a sentence.
Jim studied in the Sweet Shop for his chemistry quiz.
A dependent clause is a group of words that contains a subject and verb but does not express a complete thought. A dependent clause cannot be a sentence. Often a dependent clause is marked by a dependent marker word. A dependent marker word is a word added to the beginning of an independent clause that makes it into a dependent clause. Some common dependent markers are: after, although, as, as if, because, before, even if, even though, if, in order to, since, though, unless, until, whatever, when, whenever, whether, and while.

[tex]6(\frac{1}{3}x+\frac{1}{2})=2x+3[/tex]
First distribute 6 through parentheses
[tex]2x+3=2x+3[/tex]
We can see both sides are equal hence for all x the equation will result with tautology (undeniable equality).
The answer is [tex]x \in \mathbb{R}[/tex].
Hope this helps.
