Answer:
we have a rule
(x-h)²+(y-v)²=r²
while h is the x intercept
v is y intercept
r is the radius
so the answer will be
x²+y²=400
or
x²+y²=20²

The first step that Juan performed to simplify the expression 3.6 + 0.4(3.8 – 5.9) – 0.5 before entering it into the calculator is shown.
4(3.8 – 5.9) – 0.5
Which statement is true?
Juan performed the first step correctly.
The first step should have been 3.6 + 0.4(–2.1) – 0.5.
The first step should have been 3.6 + 0.4(2.1) – 0.5.
The first step should have been 3.6 + 1.52 – 5.9 – 0.5.

Describe the graph of the equation y = 0. Is the equation a function?
vertical line; yes
horizontal line; yes
vertical line; no
horizontal line; no
Answer: B. horizontal line; yes
Use the slope-intercept form to find the slope and y-intercept.
Slope:
0
y-intercept:
(0,0)
Yes it is a function. It is a horizontal line.
Every point on this line is of the form (x,4) where x can be any number you want. The y coordinate is fixed at 4 and cannot change. Two points on this line are (0,4) and (1,4). The horizontal line goes through 4 on the vertical y axis.
Why is it a function? Because it is impossible to draw a vertical line through more than one point on the graph of y = 4. The graph passes the vertical line test. Put another way, for any x input, there is exactly one y output.
Side Note: y = 4 is the same as y = 0x+4. Note how its in the form y = mx+b
m = 0 is the slope
b = 4 is the y intercept
Step-by-step explanation: A. vertical line; yes
horizontal line; yes
Yes! Horizontal line represents a function y = f(x)
(1):Firstly, lets understand a function. For a function to be defined, we have a set of independent variables(inputs) (Domain), a set of dependent variables (outputs) (Codomain). And a relation between the variables.
(2): Each input in X must be related to exactly one output in Y. Or else it won't represent a function.. like in the following image.. y is a function of x.Because each element ofX has one& only one image in Y

•V(n)=4+(0.3)^n
•V(n)=4+(1.3)^n
•V(n)=4(0.3)^n
•V(n)=4(1.3)^n
Answer:
Step-by-step explanation:
[tex]V(n)=4(1.3)^n[/tex]
Answer:
V(n)=4(1.3)^n
Step-by-step explanation:
4 is the original value
1.3x is how much the value multiplies every year
n is the amount of years
It's not the 1st or 3rd since that would be depreciating value
It's not the 2nd because that's adding a value instead of multiplying the original
You can buy 6 cans for green beans at the Sendiks for $3.80. You can buy 12 of the same cans of beans at
Sam's Club for $6.90. Which place is the better buy? Show the work to prove your answer.
Answer:
Sendiks.
Step-by-step explanation:
Sendiks- 6 ÷ 3.80= $1.58 per can
Sam's Club- 12÷6.90= $1.74 per can

Emily saved $100 to buy a new laptop. If the laptop she wants cost $544 and she earns $12 a week how long will it take for Emily to get enough money?
Create an equation for the problem here. Don't put any spaces.
How many weeks will it take?
Answer:
Take the number of weeks as x
12x = 544 - 100
x =444/12
x = 37
Thus it would take her 37 weeks to buy her a laptop

Step-by-step explanation:
The triangles are similar, so we can use ratios
15 12 -2
------ = --------------
15+? 12
15 10
------ = --------------
15+? 12
Using cross products
15 * 12 = 10 ( 15+?)
180 = 10 ( 15+?)
Divide each side by 10
18 = 15+?
Subtract 15 from each side

A line passes through the points (-4,-1) and (4,3). A second line passes through the points (-2,-2) and (2,6). At what point do the two lines intersect
Answer:
(-2/3 , 2/3)
Step-by-step explanation:
Line 1: (-4,-1) (4,3)
m = (3 - -1) / (4 - -4) = 4/8 = 1/2
equation: (y-3)/(x-4) = 1/2 y-3 = 1/2 x - 2
y = 1/2 x + 1 ....(1)
Line 2: (-2,-2) (2,6)
m = (6 - -2) / (2 - -2) = 8/4 = 2
equation: (y-6)/(x-2) = 2 y-6 = 2x - 4
y = 2x + 2 ...(2)
(2)-(1): 0 = 3/2x + 1
3/2 x = -1 x = - 2/3
y = 1/2 * (-2/3) + 1 = 2/3

Solve: 5x=-6x+9
A: x= -9
B: x= -9/11
C: x= 9
D: x= 9/11
Answer:
x = 9/11
Step-by-step explanation:
5x = -6x + 9
Add 6x to both sides
11x = 9
Divide both sides by 11
x = 9/11
Answer:
X Equals 9/11
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable. So X will equal 9/11, which in decimal form is 0.81.

We know that oppostie sides of a rectange have to be equal
therefore
18=10+2x
solve for x
8=2x
x=4
Answer:
The value of x is 4
Step-by-step explanation:
For a given rectangle
Lenght (l) = 2y = 10
Breadth (b) = 10 + 2x = 18
Here,
2y = 10 ...(1)
10 + 2x = 18 ...(2)
Now, For x
10 + 2x = 18
2x = 18 - 10
2x = 8
x = 8/2
x = 4
Thus, The value of x is 4

Answer:
I believe it's 1/3
I haven't done these in a while, but basically since there is 6 places and it's asking the probability of it landing on 2 out of the 6, so the answer would be 2/6. Since the answer isn't there, just simpify. 2/6 simplified is 1/3. I'm so sorry if wrong, I haven't done this in a while!
