What is the answer? And how do I Solve, you get brainiest if you show steps clearly.

scoundrel [369]

Step-by-step explanation:

solution,

given

DF = 42

DE = 7x+1

EF = 4x-3

DE = ?

here,

or, DF = DE +EF

or, 42 = 7x+1+4x-3

or, 42 = 11x-2

or, 42+2 = 11x

or, 44/11 = x

or, 4 = x

then,

replacing value of x in DE

DE = 7x+1

= 7*4+1

= 28+1

= 29

Graph the function h(x) = |x| + 4

trasher [3.6K]

Answer:

The graph of this function would be a v shape in which the slope is equal to 1 on both sides. The graph would start at (0, 4).

Step-by-step explanation:

We can tell this since the x has no coefficient. We can also tell this because the 4 is outside of the parenthesis.

What is the value of x in the equation below? 1+2eX+1 = 9

Monica [59]

The value of x is 1.252762968495368

Solution:

Given that,

We have to find the value of x in given equation

Given equation is:

$1+2e^x + 1 = 9$

Simplify the left side of equation

$2+2e^x = 9$

Move 2 from left side to right side of equation

$2e^x = 9-2\\\\2e^x= 7$

Therefore,

$e^x = \frac{7}{2}\\\\e^x = 3.5$

Taking ln on both sides

ln and e cancels each other each other

$x = ln\ 3.5$

Therefore,

x = 1.252762968495368

Thus the value of x is found
