(x,y)
sub given points and see if true

A, (0,-13)
x=0
y=-13
3(-13)=5(0)-13
-39=0-13
-39=-13
false (other user was just guessing)

B. (3,1)
x=3,
y=1
3(1)=5(3)-13
3=15-13
3=2
false

C. (7,7)
x=7
y=7
3(7)=5(7)-13
21=35-13
21=22

Answer:

<em>It will take approximately 34.13 years</em>

Step-by-step explanation:

The function G(t) below represents the amount of money in some account t years after the account is opened for The Johnson's daughter Gabriella:

$G(t)= 63,000(1+ .0255/4)^ {4t}$

It's required to find the number of years (t) it will take for the account to reach G(t)=150,000. We need to solve the equation:

$63,000(1+ .0255/4)^ {4t}=150,000$

Dividing by 63,000 and simplifying:

$\displaystyle (1+ .0255/4)^ {4t}=\frac{150,000}{63,000}=2.38095$

Taking logarithms:

$\displaystyle \log(1+ .0255/4)^ {4t}=\log 2.38095$

Applying logarithms property:

$\displaystyle (4t) \log(1+ .0255/4)=\log 2.38095$

Solving for t:

$\displaystyle 4t =\frac{\log 2.38095}{\log(1+ .0255/4)}$

$\displaystyle t =\frac{\log 2.38095}{4\log(1+ .0255/4)}$

Calculating:

$\displaystyle t =\frac{0.37675}{0.01104}$

$\boxed{t \approx 34.13}$

It will take approximately 34.13 years

Help please I need it as soon as possible

MAVERICK [17]

Answer:

y=1/2+3

Step-by-step explanation:

For the first one, 0 and 3. 0/2 is not possible so we just add 3.

Second, 1/2 is 0.5 of 1/2. Plus 3 is 3 1/2.

Third, 2/2 = 1 + 3 = 4.

And last, 3/2 = 1.5 or 1 1/2. 1 1/2 + 3 is 4 1/2

Hope this helps!
