y=?

Y=-4x-3y=-2x+1x=?y=?

Answers

Answer 1

Answer:

x = -2

y = 5

Step-by-step explanation:

y = -4x - 3

y = -2x + 1             Multiply this whole equation by -1

-1(y = -2x + 1) = -y = 2x - 1

y = -4x - 3

-y = 2x - 1

0 = -2x - 4

4 = -2x

x = -2

y = -4x - 3      (Plug in x)

y = -4(-2) - 3

y = 8 - 3

y = 5

How many solutions can a system of linear equations have?

Answers

Answer: One

Step-by-step explanation:

Y= -6/5x-7 and y=2/5x+1

Answers

Answer:

x = -5

y = -1

Step-by-step explanation:

Y= -6/5x-7 and y=2/5x+1

then:

-6/5x - 7 = 2/5x + 1

simplify:

-8/5x = 8

divide both sides by 8:

-1/5x = 1

multiply both sides by 5:

-x = 5

x = -5

y = 2/5(-5) + 1 = -2 + 1 = -1

Answers

Answer:

Step-by-step explanation:

The location of point G  which partitions the directed line segment from D to F into a 5:4 ratio is; x = 3

Division of a Line Segment

The formula for coordinate of a point that divides a line segment in a ration is given by;

x = (mx₂ + nx₁)/(m + n)

We are given the ratio 5:4

Thus m = 5 and n = 4

The endpoints of DF are D(-2) and F(7)

Thus;

x = ((5*7) + 4(-2))/(5 + 4)

x = 27/9

x = 3

Thus, the location of point G  which partitions the directed line segment from D to F into a 5:4 ratio is x = 3

Solve for x in the diagram below.

Answers

Answer:

x = 20°

Step-by-step explanation:

here's your solution

=> it is given that whole angle is 90°

=> so, x + (3x + 10) = 90°

=> x + 3x + 10 = 90°

=> 4x + 10 = 90°

=>4x = 90 - 10

=> 4x = 80°

=.

=> x = 80/4

=> x = 20°

one angle is 20° and other 70°

hope it helps

Answer:

20 is your answer

x+3x+10=90 being right angle

4x=90-10

x=80/4=20

In 1979, the price of electricity was $0.05 per kilowatt-hour. The price of electricity has increased at a rate of approximately 2.05% annually. If t is the number of years after 1979, create the equation that can be used to determine how many years it will take for the price per kilowatt-hour to reach $0.10. Fill in the values of A, b, and c for this situation. Do not include dollar signs in the response.
c=A(b)^x

Answers

The equation that can be used to determine the number of years it would take for the price to be $0.10 is 0.10 = 0.05(1.0205)^t.

What is the equation that models the increase?

The equation that would be used is an exponential equation. An exponential equation is used because the rate of increase is a compound growth.

Exponential equations usually have this form: FV = PV( 1 + r)^t

Where:

FV = future value PV = present value r = rate of growth t = time

0.10 = 0.05(1.0205)^t.
