A park has a grinkgo tree a dogwood tree and 2 blue spruce trees the blue spruce trees are 8 years old the grinkgo tree is 2 yea

enot [183]

Answer:

The age of the grinkgo tree is 10 years old and the age of the dogwood tree is 4 years old

Step-by-step explanation:

Let

x -----> the age of the grinkgo tree

y -----> the age of the dogwood tree

z -----> the age of the blue spruce tree

we know that

$x=3y-2$ ------> equation A

$z=8$ ----> equation B

$x=\frac{1}{2}(y+2z)$

substitute the value of z

$x=\frac{1}{2}(y+2(8))$

$x=\frac{1}{2}(y+16)$ -----> equation C

equate equation A and equation C and solve for y

$3y-2=\frac{1}{2}(y+16)$

$6y-4=(y+16)$

$6y-y=16+4$

$5y=20$

$y=4$

Find the value of x (equation A or equation C)

$x=3(4)-2=10$

therefore

The age of the grinkgo tree is 10 years old and the age of the dogwood tree is 4 years old

Solve and graph the absolute value inequality: |4x + 1| ≤ 5. a. number line with closed dots on −1.5 and 1 with shading going in

Afina-wow [57]

4x + 1 <= 5 ; x = 1

4x +1 >= -5 ; x = - 1.5

Now we know that x is between -1.5 and 1, so you should shade between -1.5 and 1. The circle will be closed since the equality is =< and =>

The answer is option D

Hope this helps
