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: You will have points plotted at +3 on the y axis, and +3 on the x axis.
The attachment shows what your graph should look like.
Step-by-step explanation:
The intercept is where the graphed line crosses an axis.
To find the y-intercept, substitute 0 for x and solve for y:
0 + y = 3. Subtracting 0, you have y = 3
So you can plot a point at +3 on the y axis.
To find the x- intercept, substitute 0 for y, and solve for x
x + 0 = 3 Again, subtracting 0, x = 3
So plot a point on the x-axis at +3
Use the line tool to connect the two points.
The problem is that 7^2 is 7*7, and the same for 8^2. The right answer is the square root of 15, or 3.87
I wanna say it’s d because of the way it’s set up, i hope this helps if not i’m really really sorry
Answer:
h=60
Step-by-step explanation:
The angle that is 120 degrees and the angle that is h degrees are called same side interior angles
Same side interior angles are supplementary, meaning that they add to 180 degrees
To find h we can use Measures addition postulate to find the unknown value h
h+120=180
h=60
