2x + y =6 y = x-3 Solve for x and y

Mathematics
1 answer:
slega [8]3 years ago
6 0

Answer:

x = 3, y=0

Step-by-step explanation:

2x + y =6

y = x-3

Substitute the second equation into the first

2x +x-3 =6

Combine like terms

3x-3 =6

Add 3 to each side

3x-3+3 = 6+3

3x= 9

Divide each side by 3

3x/3 = 9/3

x =3

Now we need to find y

y = x-3

y = 3-3=0

y=0

Algebra
nevsk [136]

Answer:

The equation is y = 3/5x - 6

Step-by-step explanation:

First we have to find the slope of the line. In order to do so, solve the first equation for y.

3x - 5y = 7

-5y = -3x + 7

y = 3/5x + 7/-5

This gives us a slope of 3/5. Given that information, we now can plug the slope and point into point-slope form and get the final equation.

y - y1 = m(x - x1)

y - -6 = 3/5(x - 0)

y + 6 = 3/5x

y = 3/5x - 6

The rectangular floor of a classroom is 32 feet in length and 36 feet in width. A scale drawing of the floor has a length of 8 i
Vanyuwa [196]

Answer:

34

Step-by-step explanation:

32 / 8 = 4
36 / 4 = 9

perimeter of rectangle = 2(Length) + 2(width)
P = 2(8) + 2(9)
P = 16 + 18
P = 34

A baseball is thrown upward and its height after t seconds can be described by formula h(t)=−16t2+50t+5. Find the maximum height
asambeis [7]

h(t) = -16t² + 50t + 5

The maximum height is the y vertex of this parabola.

Vertex = (-b/2a, -Δ/4a)

The y vertex is -Δ/4a

So,

The maxium height is -Δ/4a

Δ = b² - 4.a.c

Δ = 50² - 4.(-16).5

Δ = 2500 + 320

Δ = 2820

H = -2820/4.(-16)

H = -2820/-64

H = 2820/64

H = 44.0625

So, the maxium height the ball will reach is 44.0625
