in what quadrant can you find the point (-5,4)
Answer:
Quadrant II
General Formulas and Concepts:
The top right square of the Cartesian Plane is the First Quadrant.
The top left square of the Cartesian Plane is the Second Quadrant.
The bottom left square of the Cartesian Plane is the Third Quadrant.
The bottom right square of the Cartesian Plane is the Fourth Quadrant.
Read the Cartesian Plane counterclockwise starting from the top right.
Step-by-step explanation:
Step 1: Define
(-5, 4)
x = -5
y = 4
Step 2: Find
We know since x = -5, our point is either going to be in Quadrant II or IIISince y is positive (4), it will go up, meaning that the point will be in Quadrant IIMarshall bought 20 refills and sold Them at $4 each. If it had cost $ 50 for the refills, what his profit or loss percentage

Si al triple del cuadrado de un número se le suma siete veces el mismo número se obtiene por resultado 10. ¿Cuál es ese número?
Answer:
The value of the number is either 1 or -10/3
Step-by-step explanation:
If the same number is added to triple the square of a number seven times, the result is 10. What is that number?
Let the number = x
Therefore, we have;
3·x² + 7·x = 10
Therefore, we have;
3·x² + 7·x - 10 = 0
Dividing by 3 gives;
x² + 7/3·x - 10/3 = 0
Factorizing gives;
(x - 1)·(x + 10/3) = 0
x = 1 or -10/3
The number is either 1 or -10/3.
9 divided by 7
Show working plz
Answer:
1
2 Remainder
Step-by-step explanation:
Step 1:
Start by setting it up with the divisor 7 on the left side and the dividend 9 on the right side like this:
7 ⟌ 9
Step 2:
The divisor (7) goes into the first digit of the dividend (9), 1 time(s). Therefore, put 1 on top:
1
7 ⟌ 9
Step 3:
Multiply the divisor by the result in the previous step (7 x 1 = 7) and write that answer below the dividend.
1
7 ⟌ 9
7
Step 4:
Subtract the result in the previous step from the first digit of the dividend (9 - 7 = 2) and write the answer below.
1
7 ⟌ 9
- 7
2
You are done.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 9 divided by 7 calculated using Long Division is:
1

Answer:
a)102 b)76.5%
Step-by-step explanation:
20 percent of 85 is 17 so you would add the two to get 102. For the second one, 65 is x percent of 85, of means multiply so 85x/100=65 85x=6500
6500/85= approximately 76.4705, rounding this to the nearest hundredth to get 76.50

A rectangle has a height that is 5 inches less than the base. If the area of the rectangle is 57 inches square, what are the height and base of the rectangle?
Answer:
The height and base of the rectangle are approximately 5.453 inches and 10.453 inches, respectively.
Step-by-step explanation:
From Geometry we remember that area of a rectangle ([tex]A[/tex]), measured in square inches, is equal to:
[tex]A = w \cdot h[/tex] (Eq. 1)
Where:
[tex]w[/tex] - Width, measured in inches.
[tex]h[/tex] - Height, measured in inches.
In addition, we get the following relationship from statement:
[tex]w = h+5\,in[/tex] (Eq. 2)
If we know that [tex]A = 57\,in^{2}[/tex], then the height of the rectangle is:
[tex]57\,in^{2} = (h+5\,in)\cdot h[/tex]
[tex]h^{2}+5\cdot h -57 = 0[/tex]
From Quadratic Formula we obtain the following roots:
[tex]h_{1} \approx 5.453\,in[/tex] and [tex]h_{2}\approx -10.453\,in[/tex]
Only the first root offers a reasonable solution, as length has always positive values. Thus, the height of the rectangle is approximately 5.453 inches.
Now we calculate the width of the rectangle from (Eq. 1):
[tex]w = \frac{A}{h}[/tex]
If we know that [tex]A = 57\,in^{2}[/tex] and [tex]h \approx 5.453 \,in[/tex], then the width of the rectangle is:
[tex]w = \frac{57\,in^{2}}{5.453\,in}[/tex]
[tex]w \approx 10.453\,in[/tex]
The height and base of the rectangle are approximately 5.453 inches and 10.453 inches, respectively.

Mary sells lemonade, and she sells 10 cents from ever cup she sells to charity. The cups of lemonade are 45 cents. One day she made $17.10. How much money did she to charity that day.
Answer:
$3.80
Step-by-step explanation:
Given that:
One cup of lemonade is sold at 45 cents.
Total money made = $17.10
Number of cups of lemonade sold can be found by dividing the total money made with the sale price of one cup of lemonade.
Number of cups of lemonade sold = [tex]\frac{\$18.10}{45\ cents} = \frac{\$18.10}{\$0.45} =38[/tex]
For each cup sold, 10 cents are donated.
Total money donated = 38 [tex]\times[/tex] 10 = 380 cents = $3.80
Therefore, the answer is:
Total money donated by Mary is $3.80

Not a function because some x values have multiple y values
Step-by-step explanation:
The meaning of a function is that an x value can only have on y value. If we were to pass a vertical line through this graph, we would find that about 2 points would be hit every time. This tells us that the x values have multiple y values and it's not a function.

y=x^2-8 is linear or nonlinear
Answer:
Nonlinear.
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
We notice that if the line is linear, x will NOT go over a degree of 1.
x² is a quadratic function, and its slope is not proportional like a linear line.
