Help!!!! I don’t really understand sloped so any help would be helpful.
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.

−24 − (18 ÷ 6) × (−12)
Answer:
12
Step-by-step explanation:
Answer:
The expression is equal to 12.
Step-by-step explanation:
[tex]-24-(18 / 6)*(-12)[/tex]
First of all, compute the parenthesis.
18 / 6 = 3
Now, replace 18/6 with 3 in our expression.
[tex]-24-(18 / 6)*(-12)[/tex]
[tex]-24-(3)*(-12)[/tex]
Next, compute the multiplication.
-12 * 3 = -36
Again, we'll replace that multiplication with negative 36:
[tex]-24-(3)*(-12)[/tex]
[tex]-24-(-36)[/tex]
Since subtracting a negative number is the same as adding a positive number:
[tex]-24-(-36) = -24+36[/tex]
Compute the addition:
[tex]-24+36=12[/tex]
[tex]-24-(18 / 6)*(-12) = 12[/tex]
Answer: The expression is equal to 12.

Step-by-step explanation:
Okay, so we know that exponents mean a number times itself.
Numerator: 4x4x4x4x4x4x4= 16,384
Denominator: 4x4x4x4x4= 1,024
Now, since it is a fraction, we divide the two.
16,384/1,024= 16
Thus, your answer is 16 ;)
Amy regularly works 20 hours per week at Smiths Dry
Cleaners Monday through Friday. She earns $10.10 per
hour and receives double-time pay for working nights. This
week Amy worked her regular 20 daytime hours plus an
additional 8 nightime hours.
What will her total pay be for the week? Round your answer
to the nearest cent.
$
15.50 x 20 = $310
31 x 8 = $248
310 + 248 = $558
Her total pay for the week is $558.
Hope you got a good grade!!! :)
Which of these values could be the slope of the line? Select two options.
–2
0
3
Answer:
3
Step-by-step explanation:
The slope is positive since it goes from the bottom left to top right so 3 is the only choice
Answer: 3
Step-by-step explanation:
The line is increasing (meaning it's pointing to the right), so that means the slope must be a positive value. When the slope is 0, the line is flat. When the slope is negative, it's decreasing (pointing to the left).

gcf of 6 and 15 is 3
Step-by-step explanation:

You go shopping at a local department store with your friend and cousin. You buy one pair of jeans, four pairs of shorts, and two shirts for $84. Your friend buys two pairs of jeans, one pair of shorts, and three shirts for $76. Your cousin buys one pair of jeans, two pairs of shorts, and one shirt for $52. How much does each item cost?
Answer: Cost per pair of jeans = $ 20
Cost per pair of shorts = $12
Cost per shirt = $8
Step-by-step explanation:
Let x= cost per pair of jeans
y = Cost per pair of shorts
z= cost per shirt.
For you, total cost = x+4y+2z= 84
For your friend, total cost = 2x+y+3z=76
For cousin, total cost = x+2y+z= 52
Required system:
[tex]x+4y+2z=84\ (i)\\ 2x+y+3z=76\ (ii)\\ x+2y+z=52\ (iii)[/tex]
from (i), [tex]x=84-4y-2z[/tex] (*)
put this in (ii) and (iii) we get
[tex]2\left(84-4y-2z\right)+y+3z=76\\\Rightarrow\ -7y-z+168=76\ (iv)\\\\ 84-4y-2z+2y+z=52\\\Rightarrow\ -2y-z+84=52 \ (v)[/tex]
from (iv), [tex]y=-\frac{z-92}{7}\ (vi)[/tex]
[tex]\mathrm{Subsititute\:}y=-\frac{z-92}{7}\ \text{in}\ (v)[/tex]
[tex]-2\left(-\frac{z-92}{7}\right)-z+84=52\\\\\Rightarrow\ -2\left(-\frac{z-92}{7}\right)-z=-32\\\\\Rightarrow\ -\frac{5z}{7}-\frac{184}{7}=-32\\\\\Rightarrow\ -5z-184=-224\\\\\Rightarrow\ -5z=-40\\\\\Rightarrow\ z=8[/tex]
[tex]\mathrm{Subsititute\:}z=8\text{ in (vi)}[/tex]
[tex]y=-\frac{8-92}{7}\\\\\Rightarrow \ y=12[/tex]
[tex]\mathrm{Subsititute\:}z=8,\:y=12\text{ in (*)}[/tex]
[tex]x=84-4\cdot \:12-2\cdot \:8\\\\\Rightarrow\ x= 20[/tex]
Hence, x= 20, y= 12 , z=8
So, Cost per pair of jeans = $ 20
Cost per pair of shorts = $12
Cost per shirt = $8
Solve to find the value for x in the linear equation: 36-4x + 5) = 12
CIE
1 Use the distributive property:
2 Use the subtraction property of equality
3. Division property of equality:
3(-4x) + 3(5) = 12
-12x + 15 = 12
- 12x + 15 - 15 = 12 - 15
-12x = -3
Intro
Answer:
[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Given expression:
3(-4x + 5) = 12
To solve for x;
Use the distributive property to open the parentheses;
3(-4x) + 3(5) = 12
-12x + 15 = 12
then, add -15 to both sides;
-12x + 15 + (-15) = 12 + (-15)
-12x = -3
divide both sides by -12;
[tex]\frac{-12x}{-12}[/tex] = [tex]\frac{-3}{-12}[/tex]
x = [tex]\frac{1}{4}[/tex]
Communities A,B and C are faced with acute water problem. The distance between communities A and B is 5km and that of A and C 7km. The angle between path AB and AC is 45degrees. If a well is dug for the three communities such that it would have equal distance to the path linking each communities. (a) Indicate by a way of sketching the exact place to dig the well? (b) Measure the distance between communities B and C?
Answer:
a) by finding the incentre
b) 5 km
Step-by-step explanation:
Let the communities A, B and C be shown by the three points of the triangle as shown in the figure below. As the angle between the path Ab and Ac is 45 degrees this is an isosceles triangle having two angles equal. As this is an isosceles triangle it must also have two sides equal .
a) the in center point can be used to have equal distance to the path linking each communities.
We take a compass and draw arcs on the two sides of the vertex and placing the compass on the arcs bisect each angle made by the triangles arms.
Joining the bisectors the lines meet at a point which is highlighted by a circle in the diagram.
This is the incentre which is equidistant from each vertex.
b) Using Pythagorus theorem
c² = a² + b²
7²= 5² + b²
b²= 24
b= 4.89= 5 km
The path between B and C is also 5 km.

e is 5 more than d.
f is 7 less than d.
Work out
e-f
Simplify your answer.
Answer:
12+2d
Step-by-step explanation:
e=5+d
f=d-7
e-f = 5+d-(d-7)
e-f = 12+2d
The solution of expression e - f is,
⇒ e - f = 12 + 2d
We have to given that,
e is 5 more than d.
And, f is 7 less than d.
Hence, It can be written as,
e is 5 more than d.
⇒ e = 5 + d
And, f is 7 less than d.
⇒ f = d - 7
So, We get;
e - f = (5 + d) - (d - 7)
Combine like terms,
e - f = 12 + 2d
Therefore, The solution of expression e - f is,
⇒ e - f = 12 + 2d
