Answer: The slope is -2.
Step-by-step explanation:
Since the line is going through the origin it means that if you find a point on the line and divided the y coordinate of point by it's x coordinate then you will get the slope or the constant change value.
The equation of a proportional line says that y = kx where k is the slope.
And to find k, you will divide y by x.
One point that is located on the line is (-1,2) The y coordinate is 2 and the x coordinate is -1.
Divide 2 by -1 to find the slope.
2/-1= -2
This means the slope is -2.

At the beginning of the school year, Jamie had $500 in her savings account. She wants to have at least $200 left in the account at the end of the school year. Each week, she withdraws $30 for spending money. To determine how many weeks she can spend $30, Jamie wrote and solved this inequality. 500 − 30x ≥ 200 −500 −500 −30x ≥ −300 x ≥ 10 Review Jamie's work. What was her error?
Answer:
Step-by-step explanation:
Given the inequality solved by H=Jamie expressed as:
500 − 30x ≥ 200
We need to calculate the range of x of the inequality to determine the number of weeks she can spend $30 as shown:
500 − 30x ≥ 200
Subtract 500 from both sides
500 − 30x - 500≥ 200 - 500
− 30x ≥ -300
Divide both sides by -30
− 30x/-30 ≥ -300/-30
x ≤ 10 (note that the inequality sign changes after dividing both sides by a negative sign)
Jamie's error was that she didn't change the sense of inequality after dividing both sides by -30 hence rendering her solution incorrect
Hence the number of weeks is less than or equal to 10.
Answer:
Answer is B
Step-by-step explanation:
Jamie should have reversed the inequality when using the division property of inequality. is the right answer hope it helps

-3x + 5 > 14
Answer:
x < -3
Step-by-step explanation:
-3x + 5 > 14
Subtract both sides by 5
-3x > 9
Divide both sides by -3 to get x alone.
x < -3

Write an exponential expression: choose a number between 0 and 10 to be the base and another number between 0 and 10, different from the base, to be the exponent. Label the base and the exponent. Then write the exponential expression in expanded form and standard form.
Answer:
2^4
2 * 2 * 2 * 2
Step-by-step explanation:
In the question above :
Write an exponential expression:
Base = number between 0 and 10
Exponent = number different from the base between 0 and 10
Let base = 2
Let exponent = 4
Hence, exponential expression will be
Base^exponent
2^4 (standard form)
Expanded form:
2 * 2 * 2 * 2 (multiply 2 in 4 places)
help me asp and explain please
Okay so, to get C you add the ones inside the triangle together.
42+58=100 Then the last angle will be 80, because when you add the three inside the triangle, you should get 180
42+58+80=180
To get D, you have to subtract 180 and 58, because 58+d will be a straight angle.
180-58=121
To get B and A, you would also have another straight angle (c, b, and a)
180-80=100
I believe that B=A, so, with the remaining 100, both A and B equal 50.
50+50+80=180
Does this help??
Answer:
a° = 58°
b = 42°
c° = 80°
d° = 122°
Step-by-step explanation:
d° can be found because a straight line has an angle of 180°.
180° - 58° = 122°
Because the angles of a triangle add up to 180°, we can find c°
58° + 42° = 100°. 180° - 100° = 80°
You can find a° subtracting 180 and d°, which is 122. 180° - 122° = 58°
You can do the same thing for b°. 180° - 42° = 138°. 180° - 138° = 42°
You can check this because b° + c° + a° should equal 180°.
58° + 42° + 80° = 180°
I hope this helps :)
9) There are six girls and 12 boys in Ms. Jeffry's environmental club. She wants to divide the students into groupS with the same number of boys and the same number of girls in each group. What is the maximum number of groups she can make? *
Answer:
Six is the most groups she can make
Step-by-step explanation:
you have six girl and 12 boys if you can only have the same number of boys and the same number of girls then you have 1 girl and 1 boy in each group and they only six girl so you can only have six group.
Answer:
6 groups because she can put 1 girl and 1 boy in a group and get 6 groups which is the maximum number of groups she can get.

In a recent year, 23% of all college students were enrolled part-time. If 6.2 million college students were enrolled part-time that year, what was the total number of college students?
Answer:
17,222,222
Step by Step Solution:
If 26% equals 6,200,000, then
1% equals 6,200,000/23, and
100% equals (6,200,000/23)*100 = 17,222,222.222222222222222222222222
Hence, there were about 17,000,000 (seventeen million) students.
To be a bit closer to the number, there where about 17,222,222 students.

Create the polynomial which has roots 3and 2
Answer:
f(x) = x² - 5x + 6
Step-by-step explanation:
Given a root of a polynomial x = a then the factor is (x - a)
Here the roots are x = 3 and x = 2 , thus the corresponding factors are
(x - 3) and (x - 2)
The polynomial is then the product of the factors, that is
f(x) = (x - 3)(x - 2) ← expand using FOIL
= x² - 5x + 6

Find the Area and Perimeter of the figure below.
6 cm
4 cm
2 cm
3 cm
Answer:
Area: 40cm^2
Perimeter:24cm
Step-by-step explanation:
Area: First of all, you can see that the missing height of the shape is 3cm. By adding 4 and 3, you get 7. Then, by multiplying 7 and the length of the shape (6cm), you get 42cm^2. After that, you have to multiply 2cm and 3cm to get the blank area in the bottom right corner to get 6cm^2. Finally, you can subtract 42cm^2(the whole area) by 6cm^2 (the blank area) to get 40cm^2.
Perimeter: Okay! To get the first missing measurement (the one on the left), you have to imagine 4cm being moved to that side. 3cm is parallel to the missing blank space under the 4cm. This means you have to get 7cm (you add 4 and 3). To get the other missing measurement (bottom of the shape) you must see that 6cm would be parallel to the bottom. Since 2cm is also parallel to the bottom, you would have to subtract 2 from 6 to get the bottom of the shape's length, which is 4. Finally, you would have to add 6, 4, 3, 2, 4 and 7 together to get 24cm.

x ^ 2–2x + 1
by splitting this equation
x ^ 2 - x -x + 1
there are a two terms x ^ 2 - x and - x + 1
we take x is common from first and -1 is common from second
x ( x - 1 ) and -1 ( x-1 )
the quadratic roots are (x-1) and (x-1)
x - 1 = 0
x = 1 in both
Therefore , the quadratic roots are 1 , 1 .
