8^{4v}+5=31
minus 5 both sides
8^{4v}=26
take the log₈ of both sides
4v=log₈26
divide both sides by 4
v=(1/4)log₈28

if yo use calculator
go back
8^{4v}=26
take ln of both sides
4vln8=ln26
divide both sides by (4ln8)
v=(ln28)/(4ln8)
evaluate
v≈0.40061291017147

Use your understanding of transformations and key features to write the slope-intercept equation of this linear function.

Answer:

y = -2x + 5

m = -1

b = 5

Step-by-step explanation:

Hello!

Slope - Intercept Form: y = mx+b

  • m = slope
  • b = y-intercept

<h3>Slope</h3>

The slope of the line is the rate of change, or how the graph changes in y as it changes in x.

Slope can be calculated by the formula: m = \frac{y_2 - y_1}{x_2 - x_1}

We need two points on the line to get the x and y-values. I'm going to choose points (0,5) and (4,-3).

Calculate Slope

  • m = \frac{y_2 - y_1}{x_2 - x_1}
  • m = \frac{5 - (-3)}{0 - 4}
  • m = -\frac{8}{4}
  • m = -2

The slope is -2.

<h3>Y-intercept</h3>

The y-intercept of the line is where the graph touches the y-axis (x = 0). It can be found by looking at the intersection of the graph and the axis.

The intersection happens at point (0,5), so the y-intercept is 5.

<h3>Equation</h3>

We found m, the slope, to be -2 and b, the y-intercept, to be 5. We can just plug it into the equation format.

Equation: y = -2x + 5

If a translation maps ∠D onto ∠B, which of the following statements is true? triangle CAB, point E is on segment AC between poin
mrs_skeptik [129]

Answer:

The correct option is;

ΔCED ~ ΔCAB

Step-by-step explanation:

Given that the translation maps angle ∠D to angle ∠B, we have;

Angle ∠D is congruent to ∠B (Given)

Segment ED is parallel to segment AB (lines having similar angles to a common transversal)

Therefore, ∠A is congruent to ∠E, (Angle on the same side of a transversal to two parallel lines)

∠C is congruent to ∠C reflexive property

Therefore, we have;

∠C ≅ ∠C

∠E ≅ ∠A  

∠D ≅ ∠B

Which gives ΔCED is similar to ΔCAB (not ΔCBA)
