Solve the system by substitution. y=2x y=10x-16

Answers

Answer 1
You would first plug in y to the other equation. It doesn’t matter which one you do. So it would look like...
2x=10x-16
Then you would move the like terms to one side
2x-10x=-16
-8x = 16
Then make the x alone by dividing -8 on both sides to solve for x.
X= 16/-8
x = -2
Hope this helped!


Answer 2

Answer:

y=4  x=2

Step-by-step explanation:

y=2x ⇒ I

y=10x-16 ⇒ II

y/2=2x/2

x=y/2 OR 1/2(y)

substitute I in II

y=10(y/2)-16

y=5y-16

SWAP -16 AND y

5y-y=16

4y/4=16/4

y=4

y=2x

(4)/2=2x/2

x=2

Answers

Given:

The graph of a line.

To find:

The y-intercept of the line.

Solution:

y-intercept is the point where the graph intersect the y-axis.

So, the y-intercept of the given line is 3.

y-intercept = 3

Therefore, the correct option is C.

A typical airplane flies at an altitude of 38,000 feet. Part A: Write an integer to represent an airplane's altitude.

Answers

Answer:

+ 38,000

Step-by-step explanation:

Given that:

Altitude of airplane = 38,000

The altitude of an object such as airplane in this scenario refers to the height of the airplane above sea level. The sea level is represented as a zero point (mid level) such that distance below are negative and those above are positive.

Hence, at an altitude of 38000 feets, altitude of airplane can be represented as +38,000 feets.

Step-by-step explanation:

Using Trigonometry,

tan33° = Opposite/Adjacent = GF/DF.

Therefore GF = DF * tan33°

= 235tan33° = 152.6.

Angle GEF = Angle EDG + Angle DGE

= 33° + 34° = 67°. (Exterior Angle Theorem)

Using Trigonometry,

sin67° = Opposite/Hypotenuse = GF/EF.

Therefore EF = GF / sin67°

= 152.6 / sin67° = 165.8.

Hence the answer is the 1st option.

Answer:

the answer is A. GF =152.6 and EG=165.8

GF= 235*(tan(33))

EG= 152.6/(sin(67))

What is an equation of the line that passes through the points (8,-1) and (4,-1)?pleaseee i need helppp

Answers

Answer:

y = -1

Step-by-step explanation:

Put the equation in the form y = mx + b where m is the slope and b is the y-intercept.

First, find the slope by doing change in y / change in x:

-1 - (-1) / 8 - 4  = 0 / 4 = 0

this means that m = 0, so the equation so far is y = 0x + b or y = b

Then, you need to find what b is and since you know x = 8 and y = -1 is a solution, you can plug that into the equation:

-1 = 0 * 8 + b

-1 = b

This means that b = -1 and the equation would be y = -1

Answer:

y=-1

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-(-1))/(4-8)

m=(-1+1)/-4=0/-4=0

slope is 0

y-y1=m(x-x1)

y-(-1)=0(x-8)

y+1=0

y=0-1=-1

y=-1
