Which function has a domain of x greater-than-or-equal-to 5and a range of y less-than-or-equal-to 3?
y = StartRoot x minus 5 EndRoot + 3
y = StartRoot x + 5 EndRoot minus 3
y = negative StartRoot x minus 5 EndRoot + 3
y = negative StartRoot x + 5 EndRoot minus 3
Answer:
The function that has a domain of 'x' greater-than-or-equal-to 5 and a range of 'y' less-than-or-equal-to 3 is;
[tex]y = -\sqrt{x - 5} +3[/tex].
Step-by-step explanation:
The domain of a function are the possible 'x' values of the function
The range of a function are the possible 'y' values of the function
The given possible functions are;
1) [tex]y = \sqrt{x - 5} +3[/tex]
The range of values for the above function are;
Domain; x ≥ 5
Range; y ≥ 3
2) [tex]y = \sqrt{x + 5} -3[/tex]
The range of values for the above function are;
Domain; x ≥ -5
Range; y ≥ -3
3) [tex]y = -\sqrt{x - 5} +3[/tex]
The range of values for the above function are;
Domain; x ≥ 5
Range; y ≤ 3
4) [tex]y = -\sqrt{x + 5} -3[/tex]
The range of values for the above function are;
Domain; x ≥ -5
Range; y ≤ -3
Therefore, the required function is the third function, [tex]y = -\sqrt{x - 5} +3[/tex].

Answer:
Percent of strike outs per-bat = 32%
Step-by-step explanation:
Given:
Number of balls strike out = 112
Total number of ball played = 350
Find:
Percent of strike outs per-bat
Computation:
Percent of strike outs per-bat = [112/350]100
Percent of strike outs per-bat = [0.32]100
Percent of strike outs per-bat = 32%

The graph of a linear inequality in two variables is the __________ containing all of its solutions.
.line
.half-plane
.parabola
.ellipse
Answer:
half-plane
Step-by-step explanation:
To draw the line of a linear inequality, we are going to draw a line that divides the coordinate plane into two parts.
Now, while the solution of the inequality lies on a part of the line, the second part of the line does not represent this solution.
Hence, we have a division into two planes. The shaded plane will represent solution to the inequality while the unshaded part will represent the part that is not a solution.
This depends on the sign of the inequality that is present .
The graph of a linear inequality in two variables is the half plain containing all of its solutions.

B. 35
С. 37
D. 79
Answer:
Step-by-step explanation:
Answer:
15
Step-by-step explanation:
I am not sure about it, but maybe 15.
<1 = (2x + 5) and <2 = (3x - 10)
<1 = (2 × 15 + 5 ) and <2 = (3 × 15 - 10)
<1 = (30 + 5) and <2 = (45 - 10)
<1 = 35 and <2 = 35

A cinema has 300 seats. 60% are filled. How many are empty? i will give brainliest
Answer:
120 seats
Step-by-step explanation:
Total seats in the hall = 300
Percentage of filled seats = 60 %
Number of seats filled = (60 / 100) 300
= 60 * 3
= 180
Therefore, number of empty seats = 300 - 180
= 120

Given the coordinate transformation f(x, y) = (- 2x, y) and the domain (0, 5), (8, - 1) and (- 6, 4) what is the range?
Answer:
{(0, 5), (-16, -1), (12, 4)}
Step-by-step explanation:
Given the coordinate transformation f(x, y) = (- 2x, y) and the domain (0, 5), (8, - 1) and (- 6, 4), to get the range, we will get f(x, y) for all the domain values
For the coordinate (0,5);
f(0, 5) = (-2(0), 5)
f(0, 5) = (0, 5)
For the coordinate (8, -1);
f(8, -1) = (-2(8), -1)
f(8, -1) = (-16, -1)
For the coordinate (-6, 4);
f(-6, 4) = (-2(-6), 4)
f(0, 5) = (12, 4)
Hence the range is {(0, 5), (-16, -1), (12, 4)}

The telephone company purchased 192 yards of wire for $2,304 in January. They
plan on making a purchase of 400 yards in February. How much will the February
purchase cost?
Answer:
Step-by-step explanation:
400yd($2304/192yd)=$4800
Answer:
400 yards of wire will cost $4,800
Step-by-step explanation:
First find the cost per yard of wire by using the equation 2,304/192 which equals 12/1, which is $12 per yard of wire. Next multiply that by 400 to get $4800, which is the total February purchase cost.

Write an equation and solve for x.
Answer:
x = 22
Step-by-step explanation:
All the sides are equal. So, it is and equilateral triangle and so all the angles will be equal.
Each angle of equilateral angle = 180/3 = 60
3x - 6 = 60 {Add 6 to both sides}
3x = 60 +6
3x = 66 {Divide both sides by 3}
x = 66/3
x = 22
