Answer:

$5 {x}^{2} + 2x = 7x + 3x \\ 5 {x}^{2} + 2x = 10x \\ 5 {x}^{2} = 10x - 2x \\ 5 {x}^{2} = 8x \\ 5x = 8 \\ x = \frac{8}{5} = 1.6 \\ thank \: you$

Draw the image of the figure with the given vertices under a dilation with the given scale factor centered at the origin j(-2,2)

Elenna [48]

Answer:

See Attachment.

Step-by-step explanation:

To create the new figure, we must multiply each coordinate by the scale factor, which is 1/2 in this case.

So j(-2,2) becomes j'(-1,1)

K(4,2) becomes K'(2,1)

L(4,-2) becomes L'(2,-1)

and M (-2,-2) becomes M'(-1,-1)

The scale factor is between 1 and 0 which means that this dilation is a reduction that will shrink the original figure to a smaller one.

Mr. Wallace needs to divide his class or 23 students into 9 groups. Each group can have two or three students. If a is the numbe

IRINA_888 [86]

Answer:

d) Mr.Wallace can use the following equations:

a + b = 9

2 a + 3 b = 23

Step-by-step explanation:

Here, the total number of students = 23

Number of groups = 9

Each group can have 2 or 3 students.

a is the number of groups of 2.

⇒ Total students in a groups = a x (Number of student in each group)

= a x 2 = 2 a

b is the number of groups of 3

⇒ Total students in b groups = b x (Number of student in each group)

= b x 3 = 3 b

So, according to the question:

Total number of groups formed = 9

⇒ a + b = 9

Total number of students = 23

or Number of students in ( a group + b group ) = 23

⇒ 2 a + 3 b = 23

Hence, Mr.Wallace can use the following equations:

a + b = 9

2 a + 3 b = 23
