Which of the binomials below is a factor of this trinomial?
inysia [295]

Answer:

5( x+5) (x-2)

Step-by-step explanation:

5x^2 + 15x -50

Factor out a 5

5(x^2 +3x - 10)

What 2 terms multiply to -10 and add to 3

5*-2 = -10

5-2 = 3

5( x+5) (x-2)

26. Figure B is the image of Figure A.
sweet [91]

The scale factor of dilation is \LARGE \frac{1}{4}.

<h3>What is scale factor?</h3>

When describing an enlargement you must state by how much the shape has been enlarged or reduced.

Area of triangle B =\frac{1}{2} * b *h

                                = 0.5 x 2 x 3

                               = 3 units

Area of triangle A =\frac{1}{2} * b *h

                                = 0.5 x 4 x 6

                               = 12 units

Scale factor =\frac{Area of \; triangle B}{Area of\; triangle A}

                    =\frac{3}{12}

                    = \frac{1}{4}

Hence, the scale factor of dilation is \LARGE \frac{1}{4}.

Answer/Step-by-step explanation:

Given:

When Jada took 8 steps, Noah took 10 steps

When Jada took 12 steps, Noah took 15 steps

a. The following table can be created as follows given that x = steps taken by Jada, and y = steps taken by Noah:

From the info given, the ratio of Noah's steps to Jada's steps is 15 : 12 = 10 : 8 = 5 : 4 = ⁵/4.

Use this ratio to create a table of 3 pairs of values as shown below.

Jada's Steps (x) ===> Noah's steps (y)

4 ===> 5

8 ==> 10

12 ==> 15

b. The graph of that shows this relationship has been attached below. Check the attachment.

c. Constant of proportionality can be calculated in each representation as follows: y/x = k. Where y is steps taken by Noah, x is for steps taken by Jada, and I is constant of proportionality.

Thus,

Constant of proportionality (k) = 15/12 = ⁵/4

This means, for every 5 steps taken by Noah, Jada takes 4 steps.

This relationship is represented by the equation, y = ⁵/4x.

The ⁵/4 in the equation is the constant of proportionality of their relationship.

d. The equation, description, graph, and table all represent the same situation because they all show the same constant of proportionality between x and y.

In the equation, ⁵/4 represents the constant of proportionality. In the graph, the slope is ⁵/4, which is also the same last constant of proportionality.

In the table, the constant of change in each pair is ⁵/4 all through.

Excellence Middle School charges $6.25 for students from all grade levels to attend the school dance. If S represents the number
vlabodo [156]
The answer would be b: 6.25(s+g)

you can already cancel out c., as there’s no way it could be 13.50

since it says it’s $6.25 dollars for all grades and you would be trying to find both 7th and 8th graders, you would need to multiply both variables by the amount they need to pay. in this case, $6.25.

What is the multiplicative rate of change for the exponential function graphed to the left?
schepotkina [342]

Answer:

The multiplicative rate of change is 3

Step-by-step explanation:

The given graph passes through the points:

(-2,\frac{2}{9}),(-1,\frac{2}{3}),(0,2),(1,6),(2,18),(3,54)

The multiplicative rate of change is the factor that multiplies each y-value to give the subsequent y-values.

We can find that factor by dividing a y-value by the previous y-value of any two consecutive y-value.

The multiplicative rate of change is \frac{6}{2}=3 or \frac{18}{6}=3 or \frac{54}{18}=3  or \frac{2}{\frac{2}{3} } =3.
