Answer:
slope = -3/2
Step-by-step explanation:
The slope of a line passing through the two points P=(x1,y1) and Q=(x2,y2) is given by m=y2−y1/x2−x1.
We have that x1=2, y1=5, x2=8, y2=−4.
Plug the given values into the formula for slope: m= (-4)-(5)/ (8)-(2) = -9/6 = -3/2
the slope of the line is m = -3/2
Answer:
The (-3x-9)=27 and (-5x-2)=10
Step-by-step explanation:
Answer:
-2.9
Step-by-step explanation:
You are really subtracting. Note that if you have a positive & negative sign directly next to each other, you will subtract:
-1.2 + (-1.7) = -1.2 - 1.7 = -2.9
-2.9 is your answer.

3/8 is greater than 1/8 because it is the same proportion and 3>1.
Answer:
D
Step-by-step explanation:
Let x be Bill’s scores.
Let y be Theo’s scores.
x + y = 90
x² = y
Solve for x in the second equation.
x = √y
Put x as √y in the first equation and solve for y.
√y + y = 90
√y = 90 - y
y = (90 - y)²
y = - y² - 180y - 8100
0 = -y² - 181y - 8100
0 = (-y+81)(y-100)
-y+81=0
y = 81
y - 100 = 0
y = 100
100 does not work if we plug in to check, so y is 81.
y = 81
Put y as 81 in the first equation and solve for x.
x + 81 = 90
x = 9
Bill scored 9 goals and Theo scored 81.
