start by plugging in the value you already have, in this case, 5 for y.

-4x-3(5)=17

-4x-15=17

-4x=32

x=-8

however, since a is a+1, a would be 7 (making x 8)

also plz tell me if i read this wrong and it’s actually 1,5 rather than a+1 and 5 cause if i did i’m so sorry lol.

\qquad\qquad\huge\underline{\boxed{\sf Answer}}

Let's evaluate ~

\qquad \sf  \dashrightarrow \: \dfrac{1}{3 {}^{ - 2}   \times {x}^{ - 4} \times  {y}^{2}  }

plug in the values :

\qquad \sf  \dashrightarrow \: \dfrac{1}{3 {}^{ - 2}  \times  {3}^{ - 4}  \times { - 1}^{2}  }

\qquad \sf  \dashrightarrow \: \dfrac{1}{3 {}^{ - 6}  {}^{ } {}^{}  }

\qquad \sf  \dashrightarrow \: {3}^{6}

\qquad \sf  \dashrightarrow \:729

Therefore, B is the Correct choice ~

Answer:

69.5

Step-by-step explanation:

Formula = 1/2 ( b1 + b2)h

base 1 + base 2 = 220

7645 x 2 = 14000 + 1200 + 80 + 10 = 15290

15290 / 220 =  764.5

H = 69.5

Lets check

1/2(220 x 69.5)

1/2(15290) = 7645

correct

If my answer is incorrect, pls correct me!

Arlecino [84]

Answer:

x=7

Step-by-step explanation:

<u>If P is the midpoint of XY, then XP = PY:</u>

  • 8x - 2 = 12x - 30
  • 12x -8x = 30 -2
  • 4x = 28
  • x= 28/4
  • x= 7

Find the point where the line crosses the x-axis. y = –5x + 5
Ronch [10]
Every point on the x-axis has y-coordinate 0.
Let y = 0, and solve for x.

y = -5x + 5

0 = -5x + 5

5x = 5

x = 1

The line crosses the x-axis at x = 1.
