the answer is D
Step-by-step explanation:
What is the y-intercept of a line that has a slope of -3 and passes through point (-5, 4)? a) -17 b) -11 c) 7 d) 19
Answer:
(- 11)
Answer b is correct
Step-by-step explanation:
To find this you can use
y = mx + c
Here,
m = slope
c = y - intercept
( -5, 4) = ( x ,y)
Let us solve now .
[tex]y = mx + c[/tex]
[tex]4 = - 3 \times - 5 + c \\ 4 = 15 + c \\ 4 - 15 = c \\ - 11 = c[/tex]
Therefore,
c = (-11)
That means y - intercept is ( -11 )

Lynn put 3 7/8 gallons of gas in her gas tank. If there are now 18 1/6 gallons in the tank, how many gallons did she start with?
x - gallons she started with
Answer:
14.3 gallons = 4 + 7.25/25 or 14.29 gallons.
Explanation:
18 1/6 gallons - 3 7/8 = 14.29
18 - 3 = 15
1/6 - 7/8 = 15 - 0.70833333333 = 14.2916666667

Solve for x.
4 (x + 1 1/3) = 9 2/3
Enter your answer as a mixed number in simplest form.
Answer:
x = 13/12
x = 1 1/12
Step-by-step:
4 (x + 1 1/3) = 9 2/3
4x + 5 1/3 = 9 2/3
subtract 5 1/3 from each side
4x = 4 1/3
divided by 4 on each side
x = 13/12
x = 1 1/2
