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.
Answer:
-10, -2, 5
Step-by-step explanation:
First, you can start by making a table.
<u>Negative | Positive</u>
-10 | 5
-2 |
The positive number is obviously the greatest, so now we look at the negative numbers. If the numbers were on a number line, -10 would be more to the left than -2, so it's the least. That leaves -2, which is greater than -10 but less than 5.
Answer:
The opening is a rectangle
AC = 18 in
BD = 18 in
Step-by-step explanation:
9+9 = 18
since the diagonals are equal, it is a rectangle.
75 is the median
And 79 is the mode
