What is the value of x?

1 answer:

7 0

Since vertical angles are congruent, (4x+7)=5(x-4). So simplifying we get 4x+7=5x-20. If we add 20 on both sides we get 4x+27=5x. Now when we subtract x from both sides, we get x=27

$\bf 5x=45^2\implies x=\cfrac{45^2}{5}\implies x=\cfrac{2025}{5}\implies x=405$

How can numbers be expressed, ordered, and compared

fiasKO [112]

Compare or order the digits that are different, Write > or <. or use a number line 44 < 72
Say:
"44 is less than 72" Or you can look at the place value. You can express using an exponent, an octet and many more

Answer:

A. vertex, (3, 0); y-intercept 4.5

Step-by-step explanation:

Rewrite in vertex form and use this form to find the vertex

( h , k ) . ( 3 , 0 )

To find the x-intercept, substitute in 0 for y and solve for x . To find the y-intercept, substitute in 0 for x and solve for y .

x-intercept(s):

( 3 , 0 )

y-intercept(s):

( 0 , 4.5 )
