Answer:
y=1/3x -3
Step-by-step explanation:
Slope intercept form is y=mx+b, where m is the <u>slope </u>and b is the <u>y-intercept, </u>or the y-value at which the line intersects the y-axis.
Your slope is 1/3, and your y-int. is -3, so substitute those values in:
y=<u>1/3</u>(x) <u>- 3</u>
Two numbers multiply into (-24) and adds up to (-10) are 2 & -12
<u>Step-by-step explanation:</u>
Here we need to find two numbers , with the following info:
Let us assume that two numbers are x & y .
two numbers multiply into (-24):
Two numbers are x and y , and there multiply is -24 i.e.
⇒ 
two numbers adds up to (-10):
Two numbers are x and y , and there addition is -10 i.e.
⇒ 
. .............. (1)
Let's solve this :
We know that , 
⇒
⇒ 
⇒ 
⇒ 
Now,
⇒ 
⇒ 
⇒ 
⇒ 
.......... (2)
Let's solve equation 1 & 2 by adding (1)+(2):
⇒ 
⇒ 
⇒ 
Putting value of in :
⇒ 
⇒ 
Therefore, two numbers multiply into (-24) and adds up to (-10) are 2 & -12.
#1 = (-1) - 7 + 4 = -3
that is the answer for number 1
#2 = she has 47 dollars she needs 3 more dollars
that is the answer.
#3 = 23 - 15 i think . the answer is positive
Answer: f(f(f(x)) = 8x - 7
Step-by-step explanation:
f(f(x)) means that we are evaluating f(x) with itself, then if f(x) = 2x - 1
f(f(x)) = 2*f(x) - 1 = 2*(2x - 1) - 1 = 4x - 2 - 1 = 4x - 3
f(f(x)) = 4x - 3
Then, we have f(f(f(x)) = 4*f(x) - 3
= 4*(2x - 1) - 3 = 8x - 4 - 3 = 8x - 7
