Answer:
{-7, 2, 8}
Step-by-step explanation:
We see that the domain is limited to three x-values: -3, 0 and 2. To find the range (which is the set of all y-values) we just need to plug-in these x-values and find the corresponding y-values.
So our equation is:
y = 3x + 2
Then we substitute for the x-values:
y = 3(-3) + 2
y = -9 + 2
y = -7
y = 3(0) + 2
y = 0 + 2
y = 2
y = 3(2) + 2
y = 6 + 2
y = 8
So our range would be {-7, 2, 8}.

Which expression has a value of 13?
(20 ÷ 4) − 4 + 3 x 2
(18 ÷ 2) + 6 ÷ 6 + 3
(16 ÷ 4) + 3 x 4 − 1
(10 ÷ 2) − 3 + 4 x 2
The expression that has a value of 13 is (18 ÷ 2) + 6 ÷ 6 + 3
The PEMDAS rule
In order to calculate the expression, we need to use the PEMDAS rule which states:
P is parenthesisE is exponentM is multiplicationD is DivisionA AdditionS is subtractionFrom the question, we are to get the expression equal to 13.
From the given expression,(18 ÷ 2) + 6 ÷ 6 + 3 is equivalent to 13;
(18 ÷ 2) + 6 ÷ 6 + 3
9 + 6 ÷ 6 + 3
9 + 1 + 3
13
Hence the expression that has a value of 13 is (18 ÷ 2) + 6 ÷ 6 + 3

Answer:
Scale factor = 3
Step-by-step explanation:
Using similar triangles
AT/AG = AB/AC
9/3 = x+10/3x-10
Cross multiply
3(x+10) = 9(3x-10)
Expand
3x+30 = 27x-90
3x-27x = -90 - 30
-24x = -120
x = 120/24
x = 5
For the larger triangle;
AC = 3x-10
AC = 3(5)-10
AC =15-10
AC = 5
AB = x+10
AB = 5+10
AB = 15
For the scale factor;
Since AT/AG = AB/AC
9/15 = 3/5
3*3/5*3 =3/5
Since the numerator and denominator of the larger triangle is multiplies by the same factor i.3 3. Hence the scale factor is 3

Answer:
[tex]\sqrt{125}[/tex]
Step-by-step explanation:
Use Pythagorean theorem since you have a right triangle [tex]15^{2}[/tex] = [tex]10^{2} + x^{2}[/tex]
225 = 100 + [tex]x^{2}[/tex] so x = [tex]\sqrt{125}[/tex]
Answer:
x = 5[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
x² + 10² = 15²
x² + 100 = 225 ( subtract 100 from both sides )
x² = 125 ( take the square root of both sides )
x = [tex]\sqrt{125}[/tex] = [tex]\sqrt{25(5)}[/tex] = 5[tex]\sqrt{5}[/tex] ← in simplest radical form

Simplify: 10x+2x-3= 9
A. x=-1
B. x=-2
C. x=1
D. x=2
Answer:
C. x = 1
Step-by-step explanation:
Combine like terms
10 + 2 − 3 = 9
12 − 3 = 9
Add 3 to both sides of the equation
12 − 3 + 3 = 9 + 3
Add the numbers
12 = 9 + 3
12 = 12
[tex]\frac{12x}{12} = \frac{12}{12}[/tex]
Cancel terms that are in both the numerator and denominator
[tex]x = \frac{12}{12}[/tex]
Divide the numbers
x = 1
Therefore the correct answer is C. x = 1

The interior angle sum of a convex polygon is 2.520 How many sides does the polygon
have?
Complete Question
The interior angle sum of a convex polygon is 2520.How many sides does the polygon have?
Answer:
16 sides
Step-by-step explanation:
The sum of angles in a polygon formula is given as:
(n - 2)180°
Where n = Number of sides of the polygon
Hence:
(n - 2)180°= 2520°
Divide both side by 180°
(n -2) = 2520/180
n - 2 = 14
n = 14 + 2 = 16
Therefore the number of sides the convex polygon has 16 sides.

The owner of a tree service has a chainsaw that uses a mixture of 200 ounces of gasoline and 2 ounces of oil. The owner needs to make at least
5 gallons of the oil-gasoline mixture.
If the owner knows that l gallon is equal to 128 fluid ounces, which inequality can be used to determine the amount of oil needed?
Answer:
You need 6oz (or 6.3366oz) of oil for the 5 gallon mixture.
Step-by-step explanation:
First, write down the essentials of this word problem.
The chainsaw uses 200 ounces gasoline (or gas) and 2 ounces oil.
The owner needs 5 gallons (640 ounces) of the mixture.
The chainsaw uses a 202 ounce mixture (200oz gasoline 2oz oil).
The mixture is 0.0099 repeating % oil and 0.9900 repeating % gasoline.
0.0099 (oil) x 640 (final mixture) = 6.3366oz repeating oil needed.
0.9900 (gas) x 640 (final mixture) = 633.6633 repeating gas needed.
This means you need 6.3366oz or 6oz (rounded) for the 5 gallon mixture.
CHECKING WORK:
6.3366 + 633.6633 = 639.99999997

The table gives the probabilities that orphaned pets in animal shelters in six cities are one of the types listed. The probability that a randomly selected orphan pet in an animal shelter in Austin is a dog is _____ %. The probability that a randomly selected orphaned dog in the same animal shelter in Austin is a Chihuahua is _____ %. (Round to the nearest hundredth.)
For all the dogs: you have 2.65+2.46+3.67+2.91 = 11.69%
Now, the probability of getting a chihuahua would be 3.44/11.69=0.2942= 24.92
Step-by-step explanation:
there ya go!!
Answer:
The probability that a randomly selected orphan pet in an animal shelter in Austin is a dog is 11.71% .
The probability that a randomly selected orphaned dog in the same animal shelter in Austin is a Chihuahua is 29.37% .
Step-by-step explanation:
2.76% + 2.86% + 3.44% + 2.65% = 11.71%
11.71 / 3.44 = .2937
.2937 = 29.37%
