Answer:

The answer is 9.

Step-by-step explanation:

Hey there, so it looks to me that you just have to subsitute 2 in for x, and solve the equation. Like this.

1. Plug in X: 3(2)^2 -2(2) + 1

2. Solve exponents (2)^2 = 4, so the equation is 3(4) - 2(2) + 1

3. Multiplication: 3 × 4 = 12, and -2 × 2 = -4, so the equation is 12 - 4 + 1

4. Addition: -4 + 1 = -3, so it is now 12-3

5. Subtraction: 12-3 = 9, so the answer is 9!

I hope this helps.

Pls help me this is due tomorrow
Anna [14]

Step-by-step explanation:

Claim: There's 14 Goats and 9 Chickens!!

Data:

Working with the Provided Information.

Let the Number of goats be x

let the Number of Chickens be y

x + y = 23..... (i)

Since the goat Possesses Two Pair of Legs... Which is a Total of 4 Legs... We say Let its Contribution be 4x.

The Chicken has Only a Pair Of Legs...Which is a total of 2 legs.... We say let its contribution be 2y

4x + 2y = 74 .....(ii)

BRINGING BOTH EQUATIONS TOGETHER.

x + y = 23

4x + 2y = 74

From Eqn i

x= 23 - y

Substitute into eqn ii

4(23 - y ) + 2y = 74

92 - 4y + 2y = 74

92 - 2y = 74

2y = 92 - 74

2y = 18

y= 9.

Substitute y into any of the eqns to get x

x + y = 23

x + 9=23

x = 23 - 9

x = 14

This simply proves that there are 14 Goats and 9 Chickens!!!.

HAVE A GREAT DAY!

Had to do it to em

Answer:

A is the correct answer

Step-by-step explanation:

When x =4 and y =-5, and you want to evaluate equation -3x+2y, you just have to apply it into the equation.

We got the equation as:

= -3x + 2y

= -3*4 + 2*(-5)

= -12 + (-10)

= -12 - 10

= -22

Hope this help you :3

In a basketball tournament, team A scored 6 more points than 3 times as many points as team B scored. Team C scored 45 more poin
velikii [3]

Answer:

"Team C scored 130 points."

Step-by-step explanation:

Let x represent how many points team B scored.

Team A: 3x + 6

Team B: x

Team C: x + 45

Total: 476 points

476 = (x) + (3x + 6) + (x + 45)

476 = x + 3x + 6 + x + 45

476 = 5x + 51

425 = 5x

x = 85

Team A:

3(85) + 6

= 261 pts

Team B:

= 85 pts

Team C:

(85) + 45

= 130 points
