Answer:
10 gallons
Step-by-step explanation:
Amy's car's maximum capacity to hold gas = 19 gallons
present amount of gas = 9 gallons
As the car's capacity is 19 gallons and present amount in tank is 9 gallons, so we can fill it as much as so that the amount in tank becomes 19 gallons.
let assume she fills x gallons
then x gallons and 9 gallons present earlier should be equal to 19 gallon, as the tank can not hold more than that.
lets write it mathematically
x + 9 = 19
subtracting 9 from both side
x + 9 - 9 = 19 - 9
=> x = 10
Thus, 10 gallons of gas is needed to fill the gas tank.
5v^2 + 25 = 115
5v^2 = 115 - 25
5v^2 = 90
v^2 = 90/5
v^2 = 18...take the square root of both sides eliminating the ^2
v = (+-) sqrt 18
v = 4.24 or v = -4.24
This situation shows that <em>the sides lengths of rectangle P is three times longer than the similar sides on Q</em>. <em>x correlates to 4 ft</em>, and <em>9 ft correlates to y</em>.
This means <em>x = 3*4</em> and <em>9 = 3*y</em>.
x = 12 (simplification)
y = 9/3 (division)
y = 3 (simplification)
Answer:
y - 5 = 1/3(x - 0)
Step-by-step explanation:
the formula for point-slope form is y2 - y1 = m(x2 - x1), where m is the slope, y1 is the y coordinate and x1 is the x coordinate
so just plug in the values into the equation:
y - 5 = 1/3(x - 0)
if you want it in slope-intercept form, the formula is: y = mx+b, where mx is the slope and b is the y intercept. it would look like the following:
y = 1/3x + 5
