Answer:
-1, 0, 1/2
Step-by-step explanation:
The function can be factored as ...
y = x(2x^2 +x -1)
y = x(2x -1)(x +1)
The factors are unique, so each zero has multiplicity 1. The zeros are the values of x that make the factors zero:
-1, 0, 1/2 . . . . zeros of the function; each with multiplicity 1

The blue print of Vanessa's new home was drawn with a scale factor of 1 foot = 0.33 inch. The
actual length of the living room was to measure 12 feet. Determine the length of the living
room shown in the blueprint.
The length of the living room in the blue print is 3.96 inch
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
According to the given question
We have,
1foot = 0.33 inch
The actual length of the living room =12feet.
Therefore,
The length of the living room in the blue print = 12 × 0.33 = 3.96inch
Hence, the length of the living room in the blue print is 3.96 inch.

how will you know if two variables are proportional on a graph?
Answer:
Compare the constants of the two variables.
Changed at the same rate, or by the same factor, then they are directly proportional. For example, since the x-coordinates changed by a factor of 2 while the y-coordinates also changed by a factor of 2, the two variables are directly proportional.

Let's solve your inequality step-by-step.
[tex]11+\frac{a}{2}\le 16[/tex]
Step 1: Simplify both sides of the inequality.
[tex]\frac{1}{2}a+11 \le 16[/tex]
Step 2: Subtract 11 from both sides.
[tex]\frac{1}{2}a+11-11\le 16-11[/tex]
[tex]\frac{1}{2}a\le 5[/tex]
Step 3: Multiply both sides by 2.
[tex]2\cdot \left(\frac{1}{2}a\right)\le (2)*(5)[/tex]

What value of x makes this equation true? 12x minus 15 = 6 minus 3x.
Answer:
x = 1.4
Step-by-step explanation:
12x - 15 = 6 - 3x
12x + 3x = 6 + 15
15x = 21
x = 1.4
Check:
12(1.4) - 15 = 1.8
6 - 3 (1.4) = 1.8
The value of x which makes the equation 12x minus 15 = 6 minus 3x true is 1.4
Given:
12x minus 15 = 6 minus 3x
12x - 15 = 6 - 3x
collect like terms
12x + 3x = 6 + 15
15x = 21
x = 21 / 15
x = 1.4
Therefore, the value of x which makes the equation 12x minus 15 = 6 minus 3x true is 1.4

Answer:
x = 7
Step-by-step explanation:
Given:
∠DEF = 117°
∠DEG = (12x + 1)°
∠GEF = (5x - 3)°
Find:
value of x
Computation:
∠DEF = ∠DEG + ∠GEF
117° = (12x + 1)° + (5x - 3)°
117° = 17 x - 2
x = 7
Answer:
7
Step-by-step explanation:
(12x + 1) + (5x - 3) = 117
17x - 2 = 117 Combine like terms
17x = 119 Add 2 to both sides
x = 7 Divide both sides by 17
Jovie is maintaining a camp fire. She has kept the fire steadily burning for 101010 hours with 151515 logs. She wants to know how many hours (h)(h)left parenthesis, h, right parenthesis she could have kept the fire going with 9 logs. She assumes all logs are the same.
How many hours can Jovie keep the fire going with 9 logs?
Answer:
Step-by-step explanation:
101010:151515 is the same as 2:3 or 2 logs for 3 hours. Using that you can set up your equation as such:
2:3
x:9
And then multiply across:
2x9 = 3x
18/3 = x
6 = x
Jovie can keep the fire running for 6 hours with 9 logs.
Another way to do this is to divide the log numbers, 9/3 = 3, and then multiply the hours by this number, 2x3 = 6.
Hope that helps
