Answer:
3x + 4y = 7
Step-by-step explanation:
The slope = difference of y values / corresponding difference in x values of the 2 points.
Here it is (4 - (-2) / (-3 - 5)
= 6 /-8 = -3/4.
Now we use the point/slope form of the equation of a line:
y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line.
We take the point (5, -2) and m = -3/4:
y - (-2) = -3/4 (x - 5)
y + 2 = -3/4x + 15/4
y = -3/4 x + 15/4 - 8/4
y = -3/4 x + 7/4 This is the equation in slope/intercept form.
To convert it to standard form we multiply through by 4 and rearrange:
4y = -3x + 7
3x + 4y = 7 is standard form.
Answer:
A
Step-by-step explanation:
5 x 10^4/2.5 x 10^2
10^2 gets cancel out by 10^4
5 gets divided by 2.5 which equals 2
Leaving us with 2 x 10^2
Answer:
x=$2.50, y=$4.00
Step-by-step explanation:
Let x=cost of the water slide
Let y=cost of the ferris wheel
System of equations:
3x+3y=19.50
2x+3y=17.00
Subtract the 2nd from the 1st to get:
x=2.50
Now plug into first equation to get:
3(2.50)+3y=19.50 so y=4.00
Check in 2nd equation:
2(2.50)+3(4) = 5+12 = 17
