Mathematics

Mashutka [201]3 years ago

Answer:

see explanation

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = 4 and (a, b) = (- 3, 7), hence

y - 7 = 4(x - (- 3)), that is

y - 7 = 4(x + 3) ← second equation in the list

wel

I can eyeball points (1/2, 8), (1,4), (2,1), (3,1/4)


The pattern is each increment of 1/2 in x divides by two.


f(x) = (\frac k 2)^{2x} = \frac{k}{4^x}


Any of the points give k=16


f(x) = 16( 4 ^{-x} )  = 4^{2-x}


Check: x=1/2 4^(3/2)=2^2=8 good


x=1 4^(2-1)=4 good


x=2 4^(2-2)=1 good


x=3 4^(2-3)=1/4 good

Maggie's brother is 3 years younger than four times her age. The sum of their ages is 62. How old is Maggie? Maggie is years old
Nadusha1986 [10]

Answer:

Maggie is 13 years old.

Step-by-step explanation:

1M + 1B = 62

rearrange to get:

1B = 62 - 1M

4M - 3 = 1B

substitute B with 62 - 1M so there is only one variable. this gives:

4M - 3 = 62 - 1M

Get all the variables on one side:

4M + 1M - 3 = 62

Get all non variables on the other side:

4M + 1M = 62 + 3

simplify:

5M = 65

Divide both sides by 5 to get the M by itself:

M = 13.

BONUS:

M + B = 62

B = 49

So her brother is 49 years old.

Maggie is 13 years old.
