What is the slope of this graph?
A. -4
B. 1/4
C. -1/4
D. 4
Answer:
-4 is the slope
Step-by-step explanation:
Because the line is going downwards that makes it a negative and if you count the boxes rise over run. You look for the point where the line meets a box perfectly and then you count the boxes down which is 4 and across which is one which makes it -4/1. So the slope is -4.

Answer:
755
Step-by-step explanation:

Kate has the $748 of money.
What is subtraction?Subtraction is a mathematic operation. Which is used to remove terms or objects in an expression.
Given:
Over the summer,
Kate earned $180 each week for 7 weeks.
That means,
she earns = 180 x 7
= $1260
She spends,
= 375 + 137
= $512
Now, she has the money = $1260 - $512
= $748
Therefore, she has the money $748.

Step-by-step explanation:
FOR X:
Let's solve your equation step-by-step.
4x+3=31
Step 1: Subtract 3 from both sides.
4x+3−3=31−3
4x=28
Step 2: Divide both sides by 4.
4x/4=28/4
x=7
FOR Y:
Step 1: Simplify both sides of the equation.
(3)(7)+6y=30
21+6y=30
6y+21=30
Step 2: Subtract 21 from both sides.
6y+21−21=30−21
6y=9
Step 3: Divide both sides by 6.
6y/6=9/6
y=3/2

i will mark brainliest if u answer
Step-by-step explanation:
The trick here is finding the scale used in the plotting. From the question, we can find two hints;
- Number of cat = 40. Since it has an equal scale for both men and women. It means the 40 / 2 = 20 (20 men and 20 women) has cat as their favorite pet.
- Since we know that the number of men is 20, we have to find what individual box represents. There are 4 boxes, this means each box would have a value of 20 / 4 = 5
Dog
For men, there are basically 5 lines (or boxes, if you prefer). This means 5 * 5 = 25
For women, there are basically 6 lines (or boxes, if you prefer). This means 6 * 5 = 30
Total frequency = 30 + 25 = 55
Hamster
For men, there are basically 3 lines (or boxes, if you prefer). This means 3 * 5 = 15
For women, there is basically 1 line (or box, if you prefer). This means 1 * 5 = 5
Total frequency = 15 + 5 = 20
Other
For men, there are basically 2 lines (or boxes, if you prefer). This means 2 * 5 = 10
For women, there are basically 3 lines (or boxes, if you prefer). This means 3 * 5 = 15
Total frequency = 10 + 15 = 25

Sienna has $8 and is saving $3 per week. Jacob has $6 and is saving $4 per week. Which model represents the equation that can determine when Sienna will have the same amount of money as Jacob?
8 Negative x tiles and 3 positive 1 tiles = 6 positive x tiles and 4 positive 1 tiles
8 x tiles and 3 positive 1 tiles = 6 x tiles and 4 positive 1 tiles
3 x tiles and 8 positive 1 tiles = 4 x tiles and 6 positive 1 tiles
3 negative x tiles and 8 positive 1 tiles = 4 x tiles and 6 positive 1 tiles
Answer:
B
Step-by-step explanation:
From the given information:
Sienna has $8 denotes the unit blocks of x tiles. So, she saved $3 per week.
This implies that:
8x + 3(1) = 8x + 3
Also,
If Jacob as well had $6 which implies 6x unit block of tiles while he saved $4;
i.e.
6(x) + 4(1) = 6x + 4
So;
the model that can determine when Sienna will have the same amount as Jacob is:
8x + 3 = 6x + 4

Reflections In The Coordinate Plane
Reflect over the x-axis:
When we reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is mapped to its opposite (its sign is changed).
The reflection of the point (x,y) across the x-axis is the point (x,-y).
Reflect over the y-axis:
When reflecting a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is mapped to its opposite (its sign is changed).
The reflection of the point (x,y) across the y-axis is the point (-x,y).
Note that the original triangle drawn by Jack and the image triangle have the same y-coordinate, but the inverse of the x-coordinate. This matches the definition of a reflection over the y-axis.
Correct answer: Choice a.
