Answer: Choice A
m = undefined
point (-2,5)
==================================================
Explanation:
The equation x = -2 describes a vertical line in which every point on this line has x coordinate -2. Two points on this line are (-2,0) and (-2,1)
Another point on this line is (-2,5) since this also has x coordinate -2.
------------------
All vertical lines have undefined slope.
Let's pick two points such as (-2,0) and (-2,1) and find the slope through them
m = (y2-y1)/(x2-x1)
m = (1-0)/(-2-(-2))
m = (1-0)/(-2+2)
m = 1/0
m = undefined, since we cannot divide by zero.

xanthe ran one quarter of a kilometer. She took a 5 minute rets, then ran another ten eighths of a kilometer. How many kilometers did she run in total.
Answer:
1 1/2 kilometers
Step-by-step explanation:
She ran 1/4 of a kilometer and then ran another 10/8 kilometer.
The 5 minute rest is to throw people off, so ignore it.
10/8 can simplify to 5/4 kilometers, so you can add that to the first quarter of a kilometer she already traveled.
5/4 plus 1/4 equals 6/4.
6/4 can be simplified to 3/2 which is equal to one and one half.
1 1/2

Find each percent increase. Round to the nearest percent
Answer:
1. 15 to 21 = 21 - 15 / 15 = 0.4*100% = 40%
2. 12 teachers to 48 teachers = 48 - 12/48 = 0.75 * 100% = 75%
3. 80 pencil to 120 pencil = 120 - 80 / 80 = 0.5*100% = 50%
4. 40 cans to 70 cans = 70 - 40 / 70 = 0.43 * 100% = 43%

Answer: Possibly, 105 cm³ if it is a triangular prism, or
Possibly 210 cm³ if it is a rectangular prism
Step-by-step explanation: Without knowing exactly what kind of prism it is, it is impossible to give an exact answer.
If the bases are triangles with altitude and and base of 5 and 6, anf the height of the prism is 7, the volume is
(6×5)/2 × 7
30/2 ×7
15 × 7 = 105 cm³ for a triangular prism
If the bases are rectangles with length and and width of 6 and 5, and the height of the prism is 7, the volume is
6×5×7 = 210 cm³ for a rectangular prism

Doughnuts at one shop cost £1.40 each.
Doughnuts at a second shop cost 20% more.
What is the difference in the cost of doughnuts at the two shops?
Given parameters:
Cost of doughnut at one shop = £1.40
Unknown
Difference in the cost of doughnuts at the two shops = ?
To find the difference in the cost of doughnuts at the two shops, we must know the cost of doughnut at the second shop;
Given that the cost of doughnut at the other shop is 20% more;
= 1.20 x £1.4
= £1.68
The difference in the cost of doughnuts = £1.68 - £1.40 = £0.28
So the answer is £0.28
-2 = g -9g what is the answer to this
Answer:G=1/4 or the same as g=0.25
Step-by-step explanation:
Answer:
1/4 is the answer.
Step-by-step explanation:
So first, you subtract the g-9g. You get -2 = -8g, correct?
Next, you divide -2 by -8, you then get -2/-8
This simplifies to 1/4.

PLS HELP! which graph is the function 3x + 2y = 8 with the given domain {-2,0,2,4}??
Answer:
D
Step-by-step explanation:
Domain of the function 3x + 2y = 8 are the possible set of x-values represented as {-2, 0, 2, 4}.
To know which graph represents the above given function, find the range values of the function by plugging in each value of x into the equation, to find y.
For x = -2,
3(-2) + 2y = 8
-6 + 2y = 8
2y = 8 + 6
2y = 14
y = 14/2
y = 7
(-2, 7)
For x = 0,
3(0) + 2y = 8
0 + 2y = 8
2y = 8
y = 8/2
y = 4
(0, 4)
For x = 2,
3(2) + 2y = 8
6 + 2y = 8
2y = 8 - 6
2y = 2
y = 2/2
y = 1
(2, 1)
For x = 4,
3(4) + 2y = 8
12 + 2y = 8
2y = 8 - 12
2y = -4
y = -4/2
y = -2
(4, -2)
The graph which shows the following set of coordinates pairs calculated above, ((-2, 7), (0, 4), (2, 1), (4, -2)), is the graph of the function 3x + 2y = 8.
Thus, the graph in option D the shows the following calculated coordinate pairs. Therefore, graph D is the answer.
1.634 x 2
show your work for brainliest please!
Answer:
3.268
Step-by-step explanation:
line up the decimals. we know that since 2 is a whole number the decimal will be behind the 2 making it 1.634 x 2.000. you can waste paper multimplying by 0, 3 times. Instead add focus on the 2 and the other numbers.
1.634
x 2.000
2x4, 2x3, 2x6, and 2x1
be sure to carrying your numbers and you will get 3268 + 0 + 0 + 0. from here there are 2 numbers behind the decimal so move the decimal left 3 places
3268.0 = 3.268

Ms. Banks walks at about 3 feet per second. How many miles per day could she travel.if she walked without
taking a break?
1
0.81 miles per day
16.36 miles per day
49.09 miles per day
2.04 miles per day
Answer:
49.09 miles per day
Step-by-step explanation:
There are 5,280 feet in one mile.
There are 60 seconds in one minute.
3 * 60 = 180 feet per minute
There are 60 minutes in one hour.
180 * 60 = 10,800 feet in one hour.
There are 24 hours in one day.
10,800 * 24 = 259,200 feet per day.
Divide to find how many miles she can walk.
259,200 / 5,280 = 49.09 miles

what is the inverse function of y=x^2+4
Answer:
does not exist
Step-by-step explanation:
The inverse relation is found by swapping x and y, then solving for y.
x = y^2 +4
x -4 = y^2
y = ±√(x -4)
This is the inverse relation. Since it is double-valued, it is not a function.
__
The function given does not pass the horizontal line test, so there is no inverse function.
