Triangle ABC is going to be dilated by a scale factor of 3.
If A is located at (-1,2), where will A' be located?
In triangle ABC, If A is located at (-1,2), A' will be located at (-3, 6)
To answer the question, we need to know what dilation is
What is dilation?Dilation is a form of transformation in which the size of an object is increased or decreased by a factor.
For any object with coordinates (x,y) dilated by a factor k, the new coordinates of the dilated object is (kx, ky).
Given that triangle ABC is going to be dilated by a scale factor of 3 and A is located at (-1, 2).
Since
(x, y) = (-1, 2) and k = 3, The coordinates of A'The new coordinates of A' = (kx, ky)
= (3 × -1, 3 × 2)
= (-3, 6)
So, A' will be located at (-3, 6)

Which function has the smallest x-intercept value, if it exists? f(x) = 3x – 9 f(x) = x2
The quadratic function f(x) = x² has the smallest x-intercept value in comparison with the linear function f(x) = 3 · x - 9, which is located at x = 0.
How to determine the x-intercept of a polynomic function
x-intercept is the point of a function that goes through the x-axis. Quadratic functions have at most two x-intercepts and linear functions have always one x-intercept.
In both expressions those intercepts are found by solving expression for x when y is equal to zero. In this question we must determine the smallest x-intercept value from one of the two polynomic functions:
a) f(x) = 3 · x - 9
3 · x - 9 = 0
x = 3
b) f(x) = x²
x² = 0
x = 0
The quadratic function f(x) = x² has the smallest x-intercept value in comparison with the linear function f(x) = 3 · x - 9, which is located at x = 0.

The number of cups of blackberries Jeff has for every 1 cup of strawberries is 8/15 while making a fruit salad.
What are the mixed numbers?Mixed numbers are the number which are used to write the whole number and the fraction number combined. As the whole number and fraction number are expressed together, thus these numbers are called mixed numbers.
Jeff is making a fruit salad. He has 1 1/3 cups blackberries. In the fractional number,

y=1/8x+3 in standard form
Answer:
[tex]x-8y=-24[/tex]
Step-by-step explanation:
Standard form of a linear equation: [tex]Ax+By=C[/tex]
(where A, B and C are integers, and A shouldn't be negative)
Given equation:
[tex]y=\dfrac{1}{8}x+3[/tex]
Multiply both sides by 8:
[tex]\implies 8 \cdot y=8 \cdot \dfrac{1}{8}x+8 \cdot 3[/tex]
[tex]\implies 8y=x+24[/tex]
Subtract 8y from both sides:
[tex]\implies 8y-8y=x+24-8y[/tex]
[tex]\implies 0=x+24-8y[/tex]
Subtract 24 from both sides:
[tex]\implies 0-24=x+24-8y-24[/tex]
[tex]\implies -24=x-8y[/tex]
In standard form:

Step-by-step explanation:
The equation to find the slope of a line is [tex]\frac{y2 - y1}{x2-x1}[/tex]. Y1 is 5, Y2 is 3, X1 is 2, and X2 is -4. Plug these numbers in to get the equation [tex]\frac{5-3}{(-4)-2}[/tex]. 5-3 = 2. (-4)-2 = -6. This gives a slope of 2/-6, which can be reduced by dividing the numerator and denominator by 2 to get a final slope of -1/3.

Negative Effects of Violent Video Games
In studies conducted by neuroscientists, it was found that teens who regularly play violent video games have lower rates of success in school than teens who do not play violent video games. The same parents who ban violent televisions shows from being watched in their homes must also be careful about the types of video games their teens play. Teens love their games, but their future is at stake.

The value of the constant of variation is 3. The correct option is the third option- 3
VariationFrom the question, we are to determine the constant of variation.
Let the constant of variation be k
From the give information,
A quantity h varies directly with w and inversely with p
That is,

Introducing the constant of variation, k, we get
[tex]h = k\frac{w}{p}[/tex]
Also, from the give information,
w = 4
p = 6
h = 2
