How many solutions does the system have, and why?
vagabundo [1.1K]
Answer:
C. there are no solutions because the slopes are the same and the y-intercepts are different.

step-by-step explanation:
y = 2/3x - 6
3y - 2x = 9
y = 0
3(0) - 2x = 9
-2x = 9
/-2 /-2
x = -9/2 = -4.5
x = 0
3y - 2(0) = 9
3y = 9
/3 /3
y = 3
(-4.5, 3)
slope 2/3
y-intercept (0, 3)
there are no solutions because the slopes are the same and the y-intercepts are different

Solve for m: 18d + 2m + 9k < 5k + 10.
lions [1.4K]
Subtract 18d from both sides

subtract 9k from both sides

simplify 5k + 10 - 18d - 9k to -4k + 10 - 18d

factor out the common term 2

divide both sides by 2

cancel 2 and now simplify brackets

Answer: D) m < -2k + 5 - 9d or the fourth option.

8. The sum of two numbers is 8 less than twice the first number. Their difference is 4 less than twice
Delicious77 [7]

Answer:

14 and 6

Step-by-step explanation:

Let's start by naming the first number x.

We can name the second number y.

We can set up equations to model our situation.

x+y=2x-8

x-y=2y-4

Let's simplify the equations.

x+y=2x-8

Subtract 2x from both sides

-x+y=-8

__________

x-y=2y-4

Subtract 2y from both sides.

x-3y=-4

Add the two equations together to eliminate x.

x-3y=-4

-x+y=-8

________

0x-2y=-12

-2y=-12

Divide both sides by -2.

y=6

The second number is 6.

Plug that back in.

x+6=2x-8

Subtract x from both sides

6=x-8

Add 8 to both sides

x=14

The first number is 14

LenKa [72]

Answer:

7.3 in

Step-by-step explanation:

Area of triangle = (1/2) *b*h

27 = (1/2) * x^2

54 = x^2

square root (54) = x

x=> 7.3484....

Rounding off to 1 decimal place, you get 7.3 in.
