Answer:

d(4)=?

where

d= distance

t= hours

In this Linear function given by the law d(t) = 12t +20 and the graph below. To find the d(4), means to find out how many miles she cycled in the instant 4 hours.

By this function, after a break , the instant t=0, she had already cycled 20 miles.

Let's calculate

d(4) = 12(4) +20

d(4) =48+20

d(4)= 68 miles

Dafna11 [192]
Part (a):
We will assume that the total amount is Jan's saving account is "m"
Now, "withdrawal" means that she took money from her account, which means that the amount of money in her account decreased by the amount she withdrew.
Sum of negative integers to show her withdrawals = -25$ - 45$ - 75$
Amount of money remaining in her account = m - 145$
The amount of money Jan withdrew = 25$ + 45$ + 75$ = 145$

Part (b):
We will assume that the total amount is Lola's saving account is "n"
Now, "withdrawal" means that she took money from her account, which means that the amount of money in her account decreased by the amount she withdrew.
Sum of negative integers to show her withdrawals = -35$ - 55$ - 65$
Amount of money remaining in her account = n - 155$
The amount of money Lola withdrew = 35$ + 55$ + 65$ = 155$

What function equation is represented by the graph? f(x)=14x+3 f(x)=−4x−3 f(x)=−14x−3 f(x)=14x−3
Vladimir [108]

See the explanation

<h2>Explanation:</h2>

Remember you have to provide complete questions in order to get exact answers. Here I'll provide a general explanation, so:

<h3>First.</h3>

f(x)=14x+3

The slope is:

m=14

The y-intercept is:

b=3

By using graphing tool, we get the first graph shown below.

<h3>Second.</h3>

f(x)=-4x-3

The slope is:

m=-4

The y-intercept is:

b=-3

By using graphing tool, we get the second graph shown below.

<h3>Third.</h3>

f(x)=-14x-3

The slope is:

m=-14

The y-intercept is:

b=-3

By using graphing tool, we get the third graph shown below.

<h3>Fourth.</h3>

f(x)=14x-3

The slope is:

m=14

The y-intercept is:

b=-3

By using graphing tool, we get the fourth graph shown below.
