Here, triangle AEN and ALG are similar.

We know that the ratio of corresponding sides of two similar triangles are equal. So,

$\frac{21}{42} =\frac{2x-9}{(2x-9)+(x+7)}\\\\\frac{1}{2} =\frac{2x-9}{3x-2}\\\\ 3x-2=4x-18\\\\-2+18=4x-3x\\\\16=x\\\\x=16\\$

What is the value of x

Lelu [443]

Answer:

x=6

Step-by-step explanation:

Because these lines are parallel, that means these angles are congruent, so you can set up an equation because they are equal to each other.

110=19x-4

add 4 to both sides

114=19x

and divide by 19

Answer choices : <br> A : x = - 5 <br> B : x = - 4 <br> C : x = 4 <br> D x = 5

Annette [7]

Answer:

x=-4

Step-by-step explanation:

$\frac{1}{4} x - \frac{1}{8} = \frac{7}{8} + \frac{1}{2} x$

first group the like terms

$\frac{1}{4} x - \frac{1}{2}x = 1$

as 1/8 plus 7/8 = 1

then add the x's together

$-\frac{1}{4} x = 1$

and finally

x = -4

Which of the following describes graphing y ≥ |x| + 4?

kolbaska11 [484]

Answer:

Translate $y=\left|x\right|$ up $4$ units and shade inside the V

Step-by-step explanation:

we know that

The function $y=\left|x\right|$ has the vertex at point $(0,0)$

The function $y=\left|x\right|+4$ has the vertex at point $(0,4)$

the rule of the translation is

$(x,y)------> (x,y+4)$

That means

The translation is $4$ units up

The solution of the inequality $y\geq\left|x\right|+4$

is the shaded area inside the V

see the attached figure to better understand the problem

therefore

the answer is

Translate $y=\left|x\right|$ up $4$ units and shade inside the V
