Moe Larry

35 + 20x 60 + 10x

35 + 20x = 60 + 10x

(show work)

x = 2.5

Moe and Larry will have the same amount of money in their savings accounts after 2.5 weeks.

Help me with the first step

grandymaker [24]

First find the area of the triangle: (4 x 6) ÷ 2 = 12
Then the area of the rectangle: 6 x 8 = 48
Last combine: 48 + 12 = 60

Lol, sorry~

Hope this helped tho

Evaluate the expression: x^2+2x−xy when x = 250 and y = −120

NikAS [45]

Answer:

33000

Step-by-step explanation:

Substituting 250 for x and -120 for y, we get:

(250)^2 + 2(250) - (250)(120) = 62500 + 500 - 30000, or

32500 + 500, or 33000

Rename 5/6 and 14/15 using the least common denominator.

baherus [9]

Answer:

$\frac{25}{30}~and~\frac{28}{30}$

Multiply 5 by 5 to get your first parameter.

$5 * 5 = 25$

Multiply 6 by 5 to get the denominator, or your second parameter.

$5 * 6 = 30$

For the second fraction, $\frac{14}{15}$ , you need to multiply both parameters by 2, similar to before, but we now must use a different number, otherwise, the denominators will not be the same.

$14 * 2 = 28$

Now, multiply 15 by 2

$15 * 2 = 30$

The last step is to put these numbers you gathered into fractions. The bigger number always goes on the bottom, referred to as the denominator, while the smaller number, referred to as the numerator, always goes on the top.

$25~and~30 -- > \frac{25}{30}$

$28~and~30-- > \frac{28}{30}$

a ball is thrown into the air with a velocity of 40 ft/s, its height in feet seconds later is given by y=40t-16t^2. a) Find the

Scorpion4ik [409]

V(t) = dy/dt = 40 - 32t
ai). average velocity = (v(0.5) - v(0))/(0.5 - 0) = ((40 - 32(0.5)) - (40 - 32(0)))/0.5 = (40 - 16 - 40)/0.5 = -16/0.5 = -32m / s

ii). average velocity = (v(0.1) - v(0))/(0.1 - 0) = ((40 - 32(0.1)) - (40 - 32(0)))/0.1 = (40 - 3.2 - 40)/0.1 = -3.2/0.1 = -32m / s

iii). average velocity = (v(0.05) - v(0))/(0.05 - 0) = ((40 - 32(0.05)) - (40 - 32(0)))/0.05 = (40 - 1.6 - 40)/0.05 = -1.6/0.05 = -32m / s

2,-10,50,-250,.. Geometric sequence

nikklg [1K]

This question is incomplete, here is the complete question

What is the recursive formula for this geometric sequence 2, -10, 50, -250, .... ?

The recursive formula for this geometric sequence is:

$a_{1}$ = 2; $a_{n}$ = (-5) • $a_{n-1}$

Step-by-step explanation:

To find the recursive formula for a geometric sequence:

Determine if the sequence is geometric (Do you multiply, or divide, the same amount from one term to the next?)
Find the common ratio. (The number you multiply or divide.)
Create a recursive formula by stating the first term, and then stating the formula to be the common ratio times the previous term.

The recursive formula is:

$a_{1}$ = first term; $a_{n}$ = r • $a_{n-1}$ , where

$a_{1}$ is the first term in the sequence
$a_{n-1}$ is the term before the nth term
r is the common ratio

∵ The geometric sequence is 2 , -10 , 50 , -250

∴ $a_{1}$ = 2

- To find r divide the 2nd term by the first term

∵ $r=\frac{a_{2}}{a_{1}}$

∴ $r=\frac{-10}{2}=-5$

- Substitute the values of $a_{1}$ and r in the formula above

∴ $a_{1}$ = 2; $a_{n}$ = (-5) • $a_{n-1}$

The recursive formula for this geometric sequence is:

$a_{1}$ = 2; $a_{n}$ = (-5) • $a_{n-1}$
