Answer:

B. Pepe's balance will be greater.

Step-by-step explanation: After the 5th month, Leo's balance will be $130 and Pepe's will be $32. The pattern Leo's balance is +$20 per month, while Pepe's is multiply the current amount by 2. For month 6 Leo will be at $150 and Pepe will be $64. After that, you'll notice that Pepe begins to catch up as he reaches triple digits in month 7. Hopefully, after that you'll be able to figure out the answer!

Endpoint: (1,7), midpoint: (-10,10)

algol [13]

The answer is (-21, 13) for The second endpoint.

Let's start by calling the known endpoint L and the unknown K. We'll call the midpoint M. In order to find this, we must first note that to find a midpoint we need to take the average of the endpoints. To do this we add them together and then divide by 2. So, using that, we can write a formula and solve for each part of the k coordinates. We'll start with just x values.

(Kx + Lx)/2 = Mx

(Kx + 1)/2 = -10

Kx + 1 = -20

Kx = -21

And now we do the same thing for y values

(Ky + Ly)/2 = My

(Ky + 7)/2 = 10

Ky + 7 = 20

Ky = 13

This gives us the final point of (-21, 13)

HELP. there are 45 coins consisting of nickels, dimes and quarter making a total of 7 dollars. the number of dimes exceeds the n

MA_775_DIABLO [31]

9514 1404 393

Answer:

Step-by-step explanation:

Let n, d, q represent the numbers of nickels, dimes, and quarters, respectively. Then we have ...

n + d + q = 45

5n +10d +25q = 700

n -d = -5

Using n=d -5, we can substitute into the first two equations:

(d -5) +d + q = 45

2d +q = 50 . . . . add 5, collect terms [eq4]

5(d -5) +10d +25q = 700

15d +25q = 725 . . . . . . . . . . add 25, collect terms [eq5]

Multiplying [eq4] equation by 3 and subtracting that from 2/5 of [eq5], we have ...

(2/5)(15d +25q) -3(2d +q) = (2/5)(725) -3(50)

6d +10q -6d -3q = 290 -150

7q = 140 . . . . . . simplify

q = 20 . . . . . . . . divide by 7

There are 20 quarters.

Зу - 2x = -2 у+ 2x = 8

Andrew [12]

Answer:

(3.25, 1.5)

Step-by-step explanation:

First, turn the 2nd equation into y=mx+b form:

у+ 2x = 8

-2x -2x

y = -2x + 8

Next Substitute:

З(-2x+8) - 2x = -2

-6x + 24 - 2x = -2

-8x + 24 = -2

Then simplify:

-8x + 24 = -2

-24 -24

-8x = -26

x = 3.25

Lastly, substitute x into any one of the original equations:

y + 2 (3.25) =8

y + 6.5 = 8

- 6.5 - 6.5

y = 1.5

please give me brainliest i worked hard on this :,)

and its 1000% correct, i checked it i promise

Which is the factorization of 8x2 13x – 6? (8x – 3)(x 2) (x – 6)(8x 1) (2x – 2)(4x 3) (4x – 1)(2x 6)

vagabundo [1.1K]

we have

$8x^2+13x - 6$

Equate the function to zero

$8x^2+13x - 6=0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$8x^2+13x = 6$

Factor the leading coefficient

$8(x^2+\frac{13}{8}x) = 6$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$8(x^2+\frac{13}{8}x) = 6$

$8(x^2+\frac{13}{8}x+\frac{169}{256}) = 6 +\frac{169}{32} \\ \\ 8(x+\frac{13}{16} )^{2} =\frac{361}{32} \\ \\ (x+\frac{13}{16} )^{2} =\frac{361}{256}\\ \\ (x+\frac{13}{16} ) =(+/-)\sqrt{\frac{361}{256}} \\ \\ (x+\frac{13}{16} ) =(+/-)\frac{19}{16} \\ \\ x1=-\frac{13}{16} +\frac{19}{16} =\frac{6}{16}\\ \\ x2=-\frac{13}{16} -\frac{19}{16}=-2$

the factorization is equal to

$8*(x-\frac{6}{16} )*(x+2)=(8x-3)*(x+2)$

therefore

the answer is

$(8x-3)*(x+2)$
