Answer:
The equation represents: A relation and a function
Step-by-step explanation:
A function is said to be a relation; however, the relation does not have to function. For a relation to result in a function, then every input gives an important output. Thus; the given information x² + y - 15 = 0 can be re-written as:
y = - x² + 15
Similarly, the equation typically illustrates a relation as well. Consequently, suppose we replace any x-value for x, then the one possible output will be for y. Hence, that is also a function.

An internet service provider is implementing a new program based on the number of connected devices in each household currently customers are charged a flat rate of 175 per month the new plan would charge a flat rate of 94 per plus an additional 450 per device connected to the network
Answer:
Following are the solution to this question:
Step-by-step explanation:
The new rate is just [tex]\$ \ 175[/tex] per month, let's call it rate A:
[tex]\to A = 175[/tex]
The new price is [tex]\$ \ 94[/tex] plus[tex]\$ \ 4.50[/tex] per device and let us name it rate B:
[tex]\to B = 93 + 2.40 \ x[/tex]
Here x is the number of service devices, In order to find x, the formula of inequalities is less than the current plan:
[tex]\to 94 + 4.50\ x < 175[/tex]
Solve the value for x:
[tex]\to 4.50\ x < 81 \\\\ \to x < 18[/tex]
There are also less than 18 units.

The hypotenuse of a right triangle is 65 m long. If one of the legs is 39 m long, how long is the other leg?
Answer:
52 m
Step-by-step explanation:
(a^2) + (b^2) = (c^2)
(39^2) + (b^2) = (65^2)
(39^2) + (b^2) = (65^2)
1521 + (b^2) = 4225
(b^2) = 2704
b = 52
Answer:
use Pythagoras theorem to solve this
[tex]C^{2}[/tex]= [tex]A^{2}[/tex]+[tex]B^{2}[/tex]
C is always the hypotenuse of a triangle
Step-by-step explanation:
[tex]65^{2}[/tex] = [tex]39^{2}[/tex] +[tex]B^{2}[/tex]
my calculator tells me that..
4225 =1521 +[tex]B^{2}[/tex]
2704 = [tex]B^{2}[/tex]
[tex]\sqrt{2704}[/tex] = B

Rectangle RSFT has vertices R(3,10), S(5,10), F(5,6) and T(3,6). RSFT was reflected over the line
y = x, to form R'S'F'T'. What are the coordinates of the vertices of the image?
Answer:
The coordinates of the vertices of the image are R' (10, 3), S' (10, 5), F' (6, 5), T' (6, 3)
Step-by-step explanation:
If the point (x, y) reflected across the line y = x, then its image is (y, x)If the point (x, y) reflected across the line y = -x, then its image is (-y, -x)Let us use the first rule above to solve the question.
∵ Rectangle RSFT has vertices R (3, 10), S (5, 10), F (5, 6), and T(3, 6)
∵ RSFT was reflected over the line, y = x
→ To find its image switch the coordinates of all the vertices
∵ R = (3, 10)
∴ R' = (10, 3)
∵ S = (5, 10)
∴ S' = (10, 5)
∵ F = (5, 6)
∴ F' = (6, 5)
∵ T = (3, 6)
∴ T' = (6, 3)
The coordinates of the vertices of the image are R' (10, 3), S' (10, 5), F' (6, 5), T' (6, 3)

A rocket's path is modeled by y=-16t2 + 80t.
When will the rocket hit the ground?
Answer:
t=5
Step-by-step explanation:
y represents height above the ground.
so when it touches the ground height above the ground =0
y=-16t²+80 t
it will hit the ground when y=0
-16t²+80t=0
-16t(t-5)=0
either t=0 or t-5=0
or t=5
t=0 gives initial value.(rejected)
t=5

Kevin moved from a city to a small town. The population of the city is 8*10^4 is about 20 times as great as the small town. What is the approximate population of the small town?
Given:
Population of city = [tex]8\times 10^4[/tex]
It is about 20 times as great as the small town.
To find:
The approximate population of the small town.
Solution:
Population of city is about 20 times as great as the small town. It means,
[tex]\text{Population of city}=20\times \text{Population of small town}[/tex]
[tex]\dfrac{\text{Population of city}}{20}=\text{Population of small town}[/tex]
On substituting Population of city = [tex]8\times 10^4[/tex], we get
[tex]\text{Population of small town}=\dfrac{8\times 10^4}{20}[/tex]
[tex]\text{Population of small town}=\dfrac{8\times 10\times 10^3}{20}[/tex]
[tex]\text{Population of small town}=4\times 10^3[/tex]
Therefore, the population of the small town is [tex]4\times 10^3[/tex].

Write an equation in point-slope form of the line that passes through the given point and with the given slope m. (-2,1); m=4
Answer:
y-1=4(x+2)
Step-by-step explanation:
plug the point in
An equation in the point-slope form of the line that passes through the given point and with the given slope m is y-1=4(x+2).
We have given that,
slope m=4 and the point (-2,1)
What is the slope point form of the line?
The slope point form of the line is

A football team needs to move the ball at least 10 yards forward from the original starting point in order to get a first down. Angel runs for 6 yards on the first play. On the second play, he is sacked for −9 yards. At least how many yards does his team need on the third play to get a first down?
Answer:
13 yards
Step-by-step explanation:
Given that:
To get a first down, ball needs to be moved 10 yards forward from original starting point.
Distance on first play = 6 yards
on second play = - 9 yards
Hence to get a first down, distance on third play should be:
Let distance needed on third play = d
Hence,
Sum of distance on all three plays should be = 10
6 + (-9) + d = 10
6 - 9 + d = 10
-3 + d = 10
d = 10 + 3
d = 13 yards

Find the distance between (-1,2) and (4,0)
Answer: The distance between (-1,2) and (4,0) is about 5.4 units
Step-by-step explanation: You can use the Pythagorean Theorem to calculate the distance.
The difference in x-values is one side of the triangle 4- (-1) = 5 Side a
The difference in y-values is the other side 0- 2 = -2 Side b
The distance you are looking for is the hypotenuse, side c
Pythagorean Theorem : substitute the numbers we found for a and b
c² = a² + b²
c² = 5² + -2²
c² = 25 + 4
c² = 29
29 is the "square on the hypotenuse." So take the square root (use a calculator)
√29 = 5.385
You can round that to 5.4 units

Ashley has 5 bags of flour. She has two smaller bags with .75 ounces in each and 3 bigger bags which has 1.14 ounces in each. How much flour does she have in total?
Answer:
4.92 ounces
Step-by-step explanation:
Ashley has 5 bags of flour
She has two smaller bags with .75 ounces in each
= 2 × 0.75 ounces
= 1.5 ounces
3 bigger bags which has 1.14 ounces in each.
= 3 × 1.14 ounces
= 3.42 ounces
How much flour does she have in total?
This is calculated as
1.5 ounces + 3.42 ounces
= 4.92 ounces
Therefore she has 4.92 ounces of flour in total.
