19 is 1:3 2:8 4:6 5:7
18 is I think... 2:4 1:7 3:5 8:6
<span>To take the inverse of a function, you switch x and y. Y = (1/4)X-12, so for the inverse X = (1/4)Y-12. Then you solve for Y. X + 12 = (1/4)Y. 4X + 48 = Y. Therefore the inverse of y=(1/4)x-12 is y=4x+48. To check, you can plug in a point. The original function has the point (4, -11), so the inverse should have the point (-11, 4). It does. 4 * -11 is -44, add 48 to that to get 4.</span>
Answer:
The correct system would be B
Step-by-step explanation:
The reason that it is B, is that we would first need an equation for the total number of baskets he made. In this one, we need the two pointers added to the three pointers to get the total of 65
w + t = 65
The second equation needs to be the total number of points (151). That should be equal to the value of the shot times the amount of them made.
2w + 3t = 151
This is option B, and is therefore the answer.
Answer:
x=3,y=7
Step-by-step explanation:
8x+3y=45
2x+3y=27
8x-2x=6x
45-27=18
<u>6</u><u>x</u><u>=</u><u>1</u><u>8</u>
6. 6
x=3
2x+3y=27
2(3)+3y=27
6+3y=27
3y=27-6
<u>3</u><u>y</u> = <u>2</u><u>1</u>
3. 3
y=7
