Answer:

So the three new vertices are (0,0)  , (-1,-0) , and (-1,3)

Step-by-step explanation:

So let's pick a point on the triangle like (-3,-1).

The center point of dilation is (3,1).  The horizontal distance that (3,1) is from (-3,-1) is 3-(-3)=6. The scale factor is 0.5 so multiply 0.5 to the horizontal distance which is 3. The vertical distance that (-3,-1) is from (3,1) is 1-(-1)=2. The scale factor is 0.5 so multiply 2 and 0.5 giving you 1.

So this means the image of the point (-3,-1) is going to be at: starting from center (3,1) move left 3 and down 1 and you are at (0,0).

Or if you prefer just use a formula

(k(x-a)+a,k(y-b)+b)

(x,y) is a point on the triangle

(a,b) is the center=(3,1)

k is the scale factor=.5

So let's do this formula to the other two points...

(x,y)=(-5,-1)

(.5(-5-3)+3,.5(-1-1)+1)

(.5(-8)+3,.5(-2)+1)

(-4+3,-1+1)

(-1,0)

Last point (x,y)=(-5,5)

(.5(-5-3)+3,.5(5-1)+1)

(.5(-8)+3,.5(4)+1)

(-1,3)

So the three new vertices are (0,0)  , (-1,-0) , and (-1,3)

A number, y, is equal to twice the sum of a smaller number and 3. The larger number is also equal to 5 more than 3 times the sma
RSB [31]

Answer:

A.

Step-by-step explanation:

<em>NOTE: The "larger number" will be referred to as y, and the "smaller number" will be referred to as x.</em>

"A number, y, is equal to twice the sum of a smaller number and 3."

This tells us that we must add our smaller number (x) to 3 within parantheses and then multiply the entire term (x+3) by 2.

y=2(x+3)

"The larger number is also equal to 5 more than 3 times the smaller number."

This tells us that we must multiply 3 against our smaller number (x) and add 5 to it.

y=3x+5

Now, to find your answer, we can put the equations in the same form as the answer choices so as to find an equivalent equation. Lets start with the first equation.

This form calls for us to have our x term first, then our y term, then our constant.

y=2(x+3)\\y=2x+6\\-2x+y=6

Now that we've gotten the equation in that form, we can see that our answer choices hold that our leading co-efficient must be positive, which we can adjust for by dividing both sides by -1.

-2x+y=6\\2x-y=-6

This makes the only possible answer choices (A) and (C).

Now, lets do our second equation. The recipe calls for the same form, again with a positive leading coefficient.

y=3x+5\\-3x+y=5\\3x-y=-5

This is only represented by choices (A) and (B).

Therefore, answer choice (A) is the only one which represents both equations.

What is the equation of the line????????
IrinaVladis [17]

Answer:

y=1/2x+2

Step-by-step explanation:

The equations come in the form of y=mx+c, where m is the gradient and c is the y-intercept. Looking at the graph we know that the y-intercept is (0,2), so that rules out options B and C.

To find the gradient is a little more tricky, but we can follow the formula:

\frac{rise}{run}, where rise is the vertical value and run is the horizontal value

So we sub in our values:

\frac{2}{4}

And simplify:

\frac{1}{2}

So now we sub in our new found values into y=mx+c:

y=1/2x+2
