During a week:
Kevin works 3z during 5 days
kevin work (4z-7) during 1 day.
Kevin work 0 during 1 day.
z=unit time
f(z)= number of hours kevin works in one week.
f(z)=5(3z)+(4z-7)+0
f(z)=15z+4z-7
f(z)=19z-7
The number of hours kevin woirs in one week in terms of z is:
f(z)=19z-7
Answer:
A, C and D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y - intercept )
here m = - 3, thus
y = - 3x + c ← is the partial equation
To find c substitute (- 1, 4) into the partial equation
4 = 3 + c ⇒ c = 4 - 3 = 1
y = - 3x + 1 ← in slope- intercept form → C
Add 3x to both sides
3x + y = 1 ← in standard form → A
-----------------------------------------------------------
The equation of a line in slope- intercept form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m = - 3 and (a, b) = (- 1, 4), thus
y - 4 = - 3(x + 1) ← in point- slope form → D
What do you mean???? Maybe give more details then I can help
Hey there again!
First , let's add 17 on each of your sides (we have to get the "X" by itself , right?
Like: -12x - 17 + 17
= -89 + 17
-89 + 17 = -72
So, divide by -12 on each of your sides since both numbers goes into 12
Like: 12x / -12 = -1
= -72 / -12 = 6
X = 6
Good luck on your assignment and enjoy your day!

Answer:
112 inches
Step-by-step explanation:
First since we are dealing with scale factor here you are going to want to divide the 48 by 3 since they are both written with yards.
After dividing you will get 16. This is how times you are going to multiply scale factor by. You then multiply 16 by 7 to get 112 inches as your answer.
