Answer:
y = 2x - 1
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 = 2
The line crosses the y- axis at (0, - 1) ⇒ c = - 1
y = 2x - 1 ← equation of line
Answer:
400
Step-by-step explanation:
2000 divided by 20% is 400
Answer:
<h2>y = -3x - 1</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:
We have two points (1, -4) and (-2, 5).
Substitute:
Substitute the value of a slope and the coordinates of the point (1, -4) to the equation of a line:
<em>add 3 to both sides</em>
Finally:
Answer:
A
Step-by-step explanation:
Hey there! I'm happy to help!
We see that Rosy uses 1/4 of the bottle to wax 2/3 of the car.
We need to 1/3 more to wax the entire car.
1/3 is half of 2/3.
We used 1/4 bottle for 2/3 of the car.
Therefore, we need half of 1/4 bottle for 1/3 more of the car.
1/4×1/2=1/8
We add this to the original 1/4 to see the total amount we used to wax the entire car.
1/4+1/8=3/8
Therefore, Rosy will use 3/8 of the bottle of car wax to wax her entire car.
