The table shows some ordered pairs that belong to the quadratic function h.
What is the range of h?
Answer:
C. Are all real numbers greater than or equal to -8.
Step-by-step explanation:
Real numbers can be said to be all continuous values of quantity, which can be negative or positive values.
The range of h, h(x), in the table given are all real numbers.
The least of the range of h on the table is -8. All the other range values, namely, -7, 1, 17, and 41 are all greater than -8. None is less than -8.
Therefore, we can conclude that the range values of h "are all real numbers greater than or equal to -8".

Which statement best describes the graph of the
linear equation 2x + 2y = 2
A. The graph has a slope of 1 and a y-intercept
of 2.
B. The graph has a slope of 1 and a y-intercept
of 1
C. The graph has a slope of -1 and a y-intercept
of 2.
D. The graph has a slope of -1 and a y-intercept
of 1
Given:
The linear equation is:
[tex]2x+2y=2[/tex]
To find:
The statement that best describes the graph of the given linear equation.
Solution:
The slope intercept form of a linear function is:
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope anf b is the y-intercept.
We have,
[tex]2x+2y=2[/tex]
It can be written as:
[tex]2y=2-2x[/tex]
[tex]y=\dfrac{2-2x}{2}[/tex]
[tex]y=1-x[/tex]
[tex]y=-x+1[/tex] (ii)
On comparing (i) and (ii), we get
[tex]m=-1,b=1[/tex]
Therefore, the graph has a slope of -1 and a y-intercept of 1. Hence option D is correct.
Five bikers join a race. In how many possible ways can they be arranged as
first, second and third placers?
1. How many positions to be filled?
Answer:
60 different possibilities
Step-by-step explanation:
Number of bikers = 5
Positions = first, second and third
First positions = all 5 riders can take the first spot = 5 possibilities
Second spot = position 1 has been filled hence number of possibilities = ( 5 - 1) = 4
Third spot = position 1 and 2 has been filled ; number of possibilities =. (5 - 2). = 3
Number of possible arrangements :
5 * 4 * 3 = 60 different possibilities
A bakery is offering a promotion where a customer can buy a dozen cookies for $10.00. Normally, the cookies cost $1.15 each. By how much is the cost of the cookies discounted? Round to the nearest whole percent, if necessary.
Answer:
28%
Step-by-step explanation:
The result is about 27.5362% so if we round it it will be 28%
Answer: 28%
Step-by-step explanation:
1.15x12=13.8
13.8-10.00=3.8
3.8/13.8=0.27536231884
To convert to percent 0.27536231884 * 100= 27.536231884 rounded 28
Gym A charges $60 a month plus $5 per visit. The monthly cost at Gym B is represented by y = 7x + 40, where x is the number of visits per month. What conclusions can you draw about the monthly costs of the gyms? Select all correct answers.
Answer:
See the explanation
Step-by-step explanation:
Given data
Gym A charges $60 a month plus $5 per visit
let the number of visits be x, and the total charge be y
Hence the total charge is expressed as
y=5x+60--------------1
Gym B is represented by
y = 7x + 40-----------2
Although I can not find any option, we can conclude that gym A monthly charge is $20 more expensive than gym B
What is m∠1? HELP please
Answer:
45 degrees
Step-by-step explanation:
The sum of all angles is 180 degrees. Since we know one is 43, we subtract it from 180. 180 - 43 is 137.
The angle with the 88 degrees next to it is supplementary to the given angle, which means the measurement of the angle next to 88 is 180 - 88, which is 92 degrees.
143 - 92 is 45. Hope this helps

Miguel and Annie ordered the same sandwich for lunch. Miguel ate 34 of his sandwich, and Annie ate 58 of her sandwich. Who ate more?
Answer:
Miguel
Step-by-step explanation:
What we know:
Miguel ate 3/4 of his sandwich.
Annie ate 5/8 of her sandwich.
First we have to make the denominators equal.
3/4×2=6/8
6 is bigger than 5 so it would be 6/8 or 3/4 and Miguel ate 3/4.

Answer:
a.) 0.51
b.) 1445
Step-by-step explanation:
a.) 5.1 x 10^-1 can be written as 5.1 x 0.1 which equals 0.51.
b.) 1.7 x 10^4 x 8.5 x 10^-2 can be simplified either by condensing 10^4 and 10^-2 to equal 10^2, or substituting the expression into a calculator.
This should equal 1.7 x 8.5 x 10^2 or 1445.

hope that helps please mark as brainliest if correct
thank you
Answer:
first option
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (6, 0) ← 2 points on the line
m = [tex]\frac{0-3}{6-0}[/tex] = [tex]\frac{-3}{6}[/tex] = - [tex]\frac{1}{2}[/tex] = - 0.5
The line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = - 0.5x + 3 ← equation of line

Half of the difference between two numbers is 2. The sum of the greater number and twice the smaller number is 13.Find the numbers
Answer:
the greatest number and the smallest number be 3 and 7 respectively
Step-by-step explanation:
Let us assume the greater number x and the smaller number be y
Now according to the question, following equation should be made
1 ÷2 (x - y) = 2
x - y = 4 ..................... (i)
And,
x + 2y = 13 ................(ii)
Now solve both the equations
-3y = -9
y = 3
Now x is
x - y = 4
x - 3 = 4
x = 7
Hence, the greatest number and the smallest number be 3 and 7 respectively
Help! x+15 is 1/2 of x+21. What is x+15?
Answer:
x=6
Step-by-step explanation:
Simplifying
x + 15 = 21
Reorder the terms:
15 + x = 21
Solving
15 + x = 21
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + x = 21 + -15
Combine like terms: 15 + -15 = 0
0 + x = 21 + -15
x = 21 + -15
Combine like terms: 21 + -15 = 6
x = 6
Simplifying
x = 6

Answer:
1. 5/6
2. 8 outta 10
3. 60%
4. 0.37
5. 20%
Step-by-step explanation:
hope this helps!
Answer:
1. 20%
2. 0.37
3. 60%
4. 8 out of 10
5. [tex]\frac{5}{6}[/tex]
Step-by-step explanation:
Percentages are just dividing by 100 because all percentages must equal up to 100 such, as 50% and 50% (50+50=100) or 60% and 40% (60+40=100)
So divide the percentage ( basically just the number not, the %) by 100. 20(%)÷ 100 = 0.2 (take out the % when you do it). 60 ÷ 100 = 0.6
8 out of 10 is 8 ÷ 10 (0.8) if. it was 10 out of 8. it would look like [tex]\frac{10}{8}[/tex] which you can divide and get 1.2 because the line above the 8 means divide.
and [tex]\frac{5}{6}[/tex] is what i just explained above ↑ divide 5 and 6, which is .83 (it is .8333333333 to infinity and beyond, but I just said 3 because dont have that line)
now that you have everything in decimals. Sort them!
0.2 (20%)
0.6(60%)
0.37
0.8 (8 out of 10)
5/6 (0.83)
(↑ not the right answer the one in the answer box is.)
Suppose that y varies directly with x and y=20 , when x =8
a : write a direct variation equation that relates x and y ??
b : find y when x =3 ??
Answer:
y = 7.5
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 20 when x = 8
20 = 8k ( divide both sides by 8 )
2.5 = k
(a)
y = 2.5x ← equation of variation
(b)
When x = 3 , then
y = 2.5 × 3 = 7.5
