Answer:
The complete set of domain (x) and range values (y) is given by:
x y
-2 39
0 13
3 11
Step-by-step explanation:
Considering the function
[tex]f(x)=-8x+13[/tex]
As we know that the range of a function consists of the entire set of all possible resulting values of the dependent variable commanly called y or f(x), once we have substituted the domain.
Now
As the x values are -2, 0, and 3. So, the domain interval is (-2,0,3).Putting x = -2 in f(x) to determine the range for the value x = -2
[tex]f(x)=-8x+13[/tex]
[tex]f(-2)=-8(-2)+13=16+13=39[/tex]
Putting x = 0 in f(x) determine the range for the value x = 0
[tex]f(x)=-8x+13[/tex]
[tex]f(0)=-8(0)+13=0+13=13[/tex]
Putting x = 0 in f(x) determine the range for the value x = 3
[tex]f(x)=-8x+13[/tex]
[tex]f(3)=-8(3)+13=-24+13=11[/tex]
Therefore, the complete set of domain (x) and range values (y) is given by:
x y
-2 39
0 13

Answer:
city y is the coldest
Step-by-step explanation:
city x = -35 c
city y = -49 f
city z = -40 f
how you do it,
to get celsius
Fahrenheit degrees minus(-) 32, multiplied by 5, and divided by 9
to get Fahrenheit
Divide by 5, multiply by nine, add 32
Answer:
-31 F = -35 C
-45 C = -49 F
-40 C = -40 F
City Y is coldest

Eight toy camels and three toy pigs cost Gary $85. Twelve toy camels cost Sherry $96. Assuming everyone bought their toys at the same store and there were no discounts, what is the cost of two toy pigs?
Answer:
2 toy pigs cost $14
Step-by-step explanation:
If 12 toy camels cost $96, I can solve ($96 / 12 = $8) to find the price of 1 toy camel. Now, I know that 1 toy camel costs $8.
If 8 toy camels and 3 toy pigs cost $85, I can multiply the price of 1 toy camel by 8 and solve ($8 x 8 = $64).
Next, I can subtract Gary's total cost by the toy camels to find how much was spent on 3 toy pigs. ($85 - $64 = $21) Therefore, 3 toy pigs cost $21.
Then, I can solve ($21 / 3 = $7) to find the price of 1 toy pig. Finally, I can multiply ($7 x 2 = $14) to find that 2 toy pigs cost $14.
Answer:
Two toy pigs cost $14.
Step-by-step explanation:
Gary bought 8 toy camels and 3 toy pigs for $85.
Sherry bought 12 toy camels for $96.
Thus, each toy camel cost $96/12=$8
Now we know Gary spent 8*$8= $64 in toy camels.
The rest of the $85, $85 - $64 = $21 was spent on the 3 toy pigs, thus each toy pig cost $21/3=$7
If one toy pig costs $7, two toy pigs cost $14.
Find the length of side x in simplest radical form with a rational denominator
Answer:
The length of x=3/1
Step-by-step explanation:
Given the right triangle
Ф = 30
We know that
sin Ф = opposite/hypotenuse
The opposite of angle 30° = x
The hypotenuse is = 6
so
sin 30 = opposite/hypotenuse
1/2 = x/6 ∵ sin 30 = 1/2
1/2 × 6 = x
6/2 = x
3/1 = x
Therefore, the length of x=3/1
the length of a rectangle is 4 feet longer than its width.its area is 32 square feet.what are its dimensions?
Answer: Length=8, Width=4
Step-by-step explanation: I did this by trial and error, but you can also use an equation. The length is x+4, the width is x. Your equation would be x(x+4)=32. That is equal to x^2+4x=32. Solve this by completing the square. X^2+4x+ (4/2)^2=32+ (4/2)^2
X^2+4x+4=36. (X+2)(x+2)=36. X+2=6, x=4.
6) Which variable equals 55?
7) Which variable equals 101?
Answer:
5) ?
6) y = 55
7) no variable equals 101 in this triangle
Step-by-step explanation:
5) There was no question for 5
6) This is the answer because:
x = 79: 65+36+x = 180, 101+x = 180, x = 79
z = 144: 180 - 36 = 44
y = 55: 36+79+(y+10) = 180, 115+(y+10) = 180, y+10 = 65, y = 55
Hope this helps!

Review the diagram.
On a coordinate plane, a vector labeled 120 meters forms angle 25 degrees with the x-axis. It goes to point mirror 1. Another vector labeled 90 meters goes from point mirror 1 to mirror 2. It forms angle 20 degrees with a horizontal line. Point mirror 2 goes to (0, 0).
A laser beam is aimed 25° from horizontal at a mirror 120 m away. The beam bounces off the mirror and continues for an additional 90 m at 20° above horizontal until it hits a target, mirror 2. What is the distance between the origination point and the target?
approximately 85 m
approximately 122 m
approximately 174 m
approximately 194 m
Answer:
Approximately 85 m
Step-by-step explanation:
Let x represent the distance between the origination point and the target
Distance between original point and mirror 1 = 120 m
Distance between mirror 1 and mirror 2 = 90 m
The measure of angle Opposite the distance between the origination point and the target = 20 + 25 = 45°
Use Cosine rule to find x as shown below:
Use The Law of Cosines to find side a first:
[tex] a^2 = b^2 + c^2 - 2bc \times Cos(A) [/tex]
Where,
a = x
b = 90 m
c = 120 m
A = 45°
Plug in the values
[tex] x^2 = 90^2 + 120^2 - 2(90)(120) \times Cos(45) [/tex]
[tex] x^2 = 22,500 - 21,600 \times Cos(45) [/tex]
[tex] x^2 = 22,500 - 15,273.5065 [/tex]
[tex] x^2 = 7,226.4935 [/tex]
Square both sides
[tex] x = \sqrt{7,226.4935} [/tex]
[tex] x = \sqrt{7,226.4935} [/tex]
x ≈ 85 m

Forty-eight 6th graders bring their lunch to school. This is thirty percent of the 6th-grade class. How many students are in the 6th grade? (number only to the nearest whole)
Answer:
160 students in the 6th grade.
Step-by-step explanation:
There are 160 students in the 6th grade because if 48 students is 30 percent then 10 percent is 16. Meaning that 100 percent would be 160.
Students l Percent
--------------l-------------------
48 = l 30
16 = l 10
160 = l 160

6 - 2/3 (x+5) = 4x solve algebraically for the exact value of x
Answer:
x = 2
Step-by-step explanation:
1 - Rewrite
6 - 2/3 (x+5) = 4x
2 - Distribute
6 - 2/3x + 10/3 = 4x
3 - Combine like terms and get x alone
6 10/3 - 2/3x = 4x
+2/3x +2/3x
6 10/3 = 4 2/3x
------------------------------- Convert to decimals
6.3333333333.... = 4.333...x
-------------------------------- Divide both sides by 4.33...x
2 = x

An employee's time at work increased from 32 hours per week to 40 hours per week. By what percentage did the
time at work per week increase?
Answer:
You have to take the ratio so you divide the new value on the old value and compare It with 100 so you write
(40)/(32)=(x)/(100)
And this means that x = 125
So the ratio of the increase of the new time is 125%
But the real increase is 125 - 100 = 25%

What are the coordinates of the vertex of the graph of the absolute value function h(x) = 3|x + 5| + 2?
Answer:
(-5,2)
Step-by-step explanation:
h(x) = 3|x + 5| + 2 is an absolute value function in vertex form. Vertex form is f(x) = a | x - h | + k with a vertex at (h,k). So find h and k in the function, 3|x + 5| + 2, but remember in the formula h is negative so flip the sign of what ever is in your function. So if h=-5 and k=2, then the vertex is (-5,2).
