I need help I will give you 10 points
KIM [24]

Answer:

k = - 2

Step-by-step explanation:

Lines g(x) and f(x) passes through the points (2, 0), (0, 2) & (4, 0), (0, 4)

Since both the lines are parallel, so slopes of lines g(x) and f(x) would be same.

Therefore,

Slope of line g = Slope of line f = (2-0)/(0 - 2) = 2/-2 = - 1

Equation of line g(x)

For point (0, 2)

y- intercept (b) = 2

y = mx + b

g(x) = - 1x + 2 [y = g(x)]

g(x) = - x + 2

Equation of line f(x)

For point (0, 4)

y- intercept (b) = 4

y = mx + b

f(x) = - 1x + 4 [y = g(x)]

f(x) = - x + 4

It is given that:

g(x) = f(x) + k

g(x) - f(x) = k

(-x + 2) - (-x + 4) = k

-x + 2 + x - 4 = k

2 - 4 = k

-2 = k

k = - 2

A=63°
bekas [8.4K]

Answer:

B. 7.35 inches

Step-by-step explanation:

In the triangle:

  • A=63°
  • c = 7.75 inch
  • B = 47°

Now we know that:

\angle A+\angle B+\angle C=180^\circ$ (Sum of angles in a \triangle)\\63^\circ+47^\circ+\angle C=180^\circ\\\angle C=180^\circ-(63^\circ+47^\circ)\\\angle C=70^\circ

Using the Law of Sines

\dfrac{a}{\sin A} =\dfrac{c}{\sin C}\\\\\dfrac{a}{\sin 63^\circ} =\dfrac{7.75}{\sin 70^\circ} \\\\a=\dfrac{7.75}{\sin 70^\circ} \times \sin 63^\circ\\\\a=7.35$ inches (to the nearest hundredth of an inch)

X=29 and y=10

You would isolate one of the variables and then plug the expression into the other equation to find the value of one variable. Then you would plug this value into the other equation to determine the value of the remaining variable.

In a certain company, there were five candidates running for President. After the vots were tallied, it turned out that Victor,
Alborosie

Considering the situation described, the classification of the elections is given as follows:

  • David came in first place.
  • Greg came in second place.
  • Victor came in third place.
  • Mac came in fourth place.
  • Bill came in fifth place.

<h3>How to find the classification of the elections?</h3>

We take the situation that is described, and build the classification from it. The classification has the following format:

P1 - P2 - P3 - P4 - P5

With P1 being the first placed candidate, P2 being the second placed candidate, and so on until P5 which is the fifth placed candidate.

From the text given in this problem, we have that:

  • Victor finished in third place, and David beat him, hence P3 = Victor, David = P1 or P2.
  • Greg didn't come in first nor in last, hence, considering that Victor is P3, Greg = P2 or P4.
  • Mac didn't win, but he finished higher than Bill, hence, considering that Mac didn't win and that Victor is P3, Mac = P4, Bill = P5.
  • From the bullet points above, we can conclude that David = P1, Greg = P2.

Hence the places of each candidate are given as follows:

  • David came in first place.
  • Greg came in second place.
  • Victor came in third place.
  • Mac came in fourth place.
  • Bill came in fifth place.
