What is the value of x in the equation of 4x + 1.3 = - 7.9
il63 [147K]

Answer:

x = -2.3

Step-by-step explanation:

4x + 1.3 = -7.9

First we want to combine the like terms.

Subtract 1.3 from both sides.

4x = -9.2

Now we want to isolate x by dividing both sides by 4.

x = -2.3

Check your answer by plugging x back into the original equation.

4x + 1.3 = -7.9

4(-2.3) + 1.3 = -7.9

Multiply.

-9.2 + 1.3 = -7.9

Add.

-7.9 = -7/9

Your answer is correct.

Hope this helps!

PLEASE ANSWER CORRECTLY!!!!!!!!!!!!!!NEED AS SOON AS POSSIBLE
Leokris [45]

Answer:

Therefore,

v=9\ meter

Step-by-step explanation:

Given:

GF = 12

GE = 16

DF = 12

CF = v

To Find:

v = ?

Solution:

In  Δ GFC and Δ GED

∠ E ≅  ∠ F …………..{ measure of each angle is 90° given }

∠ G ≅ ∠ G    ……….....{Reflexive Property}      

Δ GFC ~ Δ GED ….{Angle-Angle Similarity test}

If two triangles are similar then their sides are in proportion.

\frac{GF}{GE} =\frac{FC}{ED} =\frac{GC}{GD}\ \textrm{corresponding sides of similar triangles are in proportion}\\  

On substituting the given values we get

\frac{12}{16} =\frac{v}{12}\\\\v=\frac{144}{16}=9\\\\\therefore v=9\ meter

Therefore,

v=9\ meter

Plss help asap :) <br><br><br> (if your reading this I hope you have a great day!)
Alika [10]
Neither.

Parallel lines have the same slope.
Perpendicular lines have negative reciprocal slopes.

Rewriting the 2nd equation to solve for y,
You get:

Y=1/5x + 1/2

The first equation slope is negative, and the second is positive. However, the second slope is 1/5, and not 5/1 - which would be the negative reciprocal of (-1/5)from the first equation.

Hope that helps!

Find the slope of the line represented by the table of values
Leya [2.2K]

Answer:

-5/3

Step-by-step explanation:

To solve for slope we use the slope formula which is y2-y1/x2-x1.

For this problem I chose the points: (-5,10) and (-2,5)

-5 is x1, 10 is y1, -2 is x2 and 5 is y2

We now plug in the points into the slope formula:

5-10/-2-(-5)= -5/3
