Which equation represents a linear function? y(x – 1) = 9 y – 5 = x(–x + 2) y(y – 1) = x + 25 y – 5 = x – 20
algol13

The linear function: y = mx + b.

y(x - 1) = 9 → xy - y = 9   NOT (xy)

y - 5 = x(-x + 2) → y - 5 = -x² + 2x   NOT (x²)

y(y - 1) = x + 25 → y² - y = x + 25   NOT  (y²)

y - 5 = x - 20 → y = x - 15   YES

One number is 5 less than 3 times the second number. The sum of the numbers is 127.
larisa86 [58]

Answer:

94 and 33

Step-by-step explanation:

x = 3y - 5

x + y = 127

3y - 5 + y = 127   Substitute in (3y-5) for x

4y - 5 = 127

4y = 132

y = 33

127 - 33 = 94

Which graph shows the solution to the system of linear inequalities below?
Talja [164]

The graph that shows the solution set for the system of inequalities is graph C.

<h3>Which is the graph of the system of linear inequalities?</h3>

Here we have the system of linear inequalities:

y < (-1/3)*x + 1\\\\y \geq  2x- 1

For the first one, we can see a line with a negative slope, and y is strictly smaller than that. So we will have a dashed line that goes down, and we need to shade the region below that line.

For the second inequality, we can see that y can be equal to or larger than the line, so this time we will use a solid line (because the points on the line are solutions). and we will shade above that line.

Also notice that this time the slope is positive, so this line goes upwards.

With that general description, we conclude that the correct option will be graph C.

Plz help I dont know this answer do if u can help plz do
WINSTONCH [101]

Answer:

The scale factor is 1/3

Step-by-step explanation:

we know that

The scale factor is equal to divide the length side of the image (square A'B'C'D') by the length side of the pre-image (square ABCD)

Let

z ---> the scale factor

x----> the length side of the image (square AB'C'D')

y----> the length side of the pre-image (square ABCD)

z=\frac{x}{y}

we have

x=2\ units\\y=6\ units

substitute

z=\frac{2}{6}

simplify

z=\frac{1}{3}

The scale factor is less than 1, so the dilation is a reduction

therefore

The scale factor is 1/3
