Which of these is a simplified form of the equation 15x + 4 = 5 + 3x + 1x? (2 points)

Mars2501 [29]

Answer:

11x=1

Step-by-step explanation:

15x+4=5+3x+1x Bring everything with an x in front of it to the left side

15x-3x-1x+4=5 Simplify the x values

11x+4=5 Bring the 4 to the right side

11x=5-4

11x=1

When a force of 30 N acts on a certain object the acceleration of the object is 5m/s2 if the force is changed to 54 N what will

PtichkaEL [24]

Answer:

The correct answer is 9 m per $second^{2}$

Step-by-step explanation:

Force is defined by mass of an object times it's acceleration.

Let the mass of the object be m kilograms.

When a force of 30 N acts on a certain object the acceleration of the object is 5 m per $second^{2}$

∴ 30 = m × 5

⇒ m = 6.

If the force is changed to 54 N, let the acceleration of the object be x m per $second^{2}$ .

∴ 54 = m × x

⇒ x = $\frac{54}{6}$ = 9

Thus when the force is 54 N, the acceleration of the object is 9 m per $second^{2}$ .

X=popcorn
x - 3.50=drink
2x+ 4(x-3.50)=32.50
2x+4x-14=32.50

Use mathematical induction to prove that the statement is true for every positive integer n. 8 + 16 + 24 + . . . + 8n = 4n(n + 1

mezya [45]

First show the statement holds for $n=1$ . The left hand side is just 8, and the right hand side is $4(1)(1+1)=8$ , so it's true.

Assume the statement holds for $n=k$ , i.e.

$8+16+\cdots+8(k-1)+8k=4k(k+1)$

and use this to show it holds for $n=k+1$ , i.e.

$8+16+\cdots+8(k-1)+8k+8(k+1)=4(k+1)(k+2)$

By the assumption above, you have

$\underbrace{8+16+\cdots+8(k-1)+8k}_{n=k}+8(k+1)=4k(k+1)+8(k+1)=4(k+1)(k+2)$

so the statement is true for all $n\ge1$ .
