-2x – 9y = 11 x – 3y = 17

Mathematics
1 answer:
AysviL [449]3 years ago
6 0
-2x-9y=11x-3y
-2x+2x-9y=11x+2x-3y
-9y=13x-3y
-9y+3y=13x-3y+3y
-6y=13x
y=-13x/6

Plug -13x/6 in for y and solve for x using one of the equations
11x-3(-13x/6)=17
11x+13x/2=17
35x/2=17
35x=34
x=34/35

Plug 34/35 in for x to solve for y now
y=(-13(34/35))/6
y=-221/105

x=34/35       y=-221/105
Now when you plug in those numbers for x and y you get 17 for both equations.

Hope I didn't mess up for your sake.

Evaluate 3x for x = −2, x = 1, and x = 3. Question 18 options: A) 1∕3, 0, 9 B) 1∕9, 3, 27 C) 9, 3, 27 D) 1∕9, 9, 27
icang [17]

Answer: B) 1/9, 3, 27

Step-by-step explanation:

Here, we need to evaluate 3^x for x = -2, x = 1, \text{ and } x = 3.

So, we substitute values of x in the given function.

At x= -2, we have

3^{-2}=\dfrac{1}{3^2}=\dfrac{1}{9}\ \ \ [\because\ a^{-n}=\dfrac{1}{a^n}]

At x= 1, we have

3^1=3

At x= 3

3^3=3\times3\times3=27

So, the values of  3^x for  

Thus, the correct answer is B) 1/9, 3, 27

Tariku was in second grade she read 6 book during each month of the year. She was in third grade she read 8 books during each mo
maks197457 [2]

Answer:

See below

Step-by-step explanation:

Tariku in second grade read 6 books each month during the year. This is equal to 6(12) = 72.

Tariku in third grade read 8 books each month during the year. This is equal to 8(12) = 96.

You can find the total amount with any of the below equations:

  • 6(12) + 8(12)
  • 12(6+8)
  • 12(14)

For a total number of months x the equations would be the same except with x instead of 12.

  • 6x+8x
  • x(6+8)
  • 14x
