Hi can anyone help me with question 1 and 3

lukranit [14]

Answer:

292 and 2092

Step-by-step explanation:

Surface area:

Wall 1: 40 x 3 = 120m^2

Wall2: 40 x 3 = 120m^2

Wall 3: 15 x 3 = 45m^2

Wall 4: 15 x 3 = 45m^2

Ceiling: 15 x 40 = 600m^2

Total : 240 + 600 + 90 = 730

So, cost of painting = 730/25 x 10 = 29.2 x 10 = 292

Total: 292 + 1800 = 2092

Write an equation in slope-intercept form for the 2 points (-2,2) and (2,-2)

Hoochie [10]

Answer:

y=-x

Step-by-step explanation:

Plug (-2,2) for y= mx+b (2=m(-2) + b)

Plug (2,-2) for y=mx +b (-2=m(2) +b)

Causing them to turn into a system of equations for y= -x

Write a system of linear equations that has the ordered pair (1,4) as it's solition

Lemur [1.5K]

The required system of equations is $x+y=5\\x-y=-3$

Step-by-step explanation:

We need to write a system of linear equations that has the ordered pair (1,4) as it's solution.

It means we need to find system of linear equations, which after being solved gives x=1 and y=4

Let the system of equations be:

$x+y=5\\x-y=-3$

I have made equations such that adding x+y gives 5 i,e (1+4=5) and subtracting x-y gives -3 (1-4=-3)

Now solving this system of equations to find value of x:

$x+y=5\,\,eq(1)\\x-y=-3\,\,eq(2)$

Adding eq(1) and eq(2)

$x+y=5\\x-y=-3\\-----\\2x=2\\x=1$

Putting value of x=1 into eq(1) to find value of y

$x+y=5\\1+y=5\\y=5-1\\y=4$

The solution set after solving system of equations is (1,4).

The required system of equations is $x+y=5\\x-y=-3$
