Answer:

<h3>13.8</h3>

Step-by-step explanation:

if Points X and Z are on a number line and point Y partition line XZ into two parts where XY: YZ = 1:4, this can be expressed as;

XY/YZ = 1/4

cross multiply;

YZ = 4XY

Also, if The coordinate of X is 1.3, and the coordinate of Y is 3.8, then the distance XY will be expressed as XY = 3.8 - 1.3

XY = 2.5

YZ = 4(2.5)

YZ = 10

Since Y is at 3.8 and YZ is 10, then coordinate Z will be YZ + Y

coordinate of Z = 10+3.8

coordinate of Z = 13.8

3.4(x+1.58)=-11.288 value of x.
Alexeev081 [22]

3.4(x+1.58)= - 11.288

Step 1: Distribute 3.4 to the numbers inside the parentheses (x+1.58)

3.4x + (3.4×1.58)= - 11.288

3.4x + 5.372 = -11.288

Step 2: Bring 5.372 to the right side by subtracting it to both sides

3.4x + (5.372 - 5.372 ) = (-11.288 - 5.372)

3.4x + (0) = (-16.66)

3.4x = -16.66

Step 3: Isolate x by dividing 3.4 to both sides

\frac{3.4x}{3.4}  = \frac{-16.66}{3.4}

x = -4.9

If you are givent two points on a line, (5,6) and (-5, -4), what is the slope of the line!
alexira [117]

Answer:

m = -1

Step-by-step explanation:

Formula we'll use: \frac{y2}{x2} -\frac{y1}{x1} =m

m = slope.

y2 = -4

x2 = -5

y1 = 6

x1 = 5

<u>Substitute -4, -5, 6, 5 into the formula:</u>

<u />\frac{-4}{-5} -\frac{6}{5} =

<u>Subtract both top and bottom:</u>

m = -10/-10

m = -1
