Answer:
see the explanation
Step-by-step explanation:
Let
x ----> number of tennis balls
y ----> number of tennis rackets
we know that
To find out the ratio of tennis balls to tennis rackets, divide the number of tennis ball by the number of tennis rackets
In this problem we have
see the model in the attached figure N 1
so
This is the equation of a linear direct variation
The relationship between the variables x and y is proportional
see the model in the attached figure N 2
Answer:
y4 - 8y3 + 8y2 + 2y + 8
—————————————
2y2
Step-by-step explanation:
Step 1 :
4
Simplify ——
y2
Equation at the end of step 1 :
y y 4
(((((y2)+————)-((2•—)•y))+——)-4y)+4
(y2) 4 y2
Step 2 :
y
Simplify —
4
Equation at the end of step 2 :
y y 4
(((((y2)+————)-((2•—)•y))+——)-4y)+4
(y2) 4 y2
Step 3 :
y
Simplify ——
y2
Dividing exponential expressions :
3.1 y1 divided by y2 = y(1 - 2) = y(-1) = 1/y1 = 1/y
Equation at the end of step 3 :
1 y2 4
(((((y2)+—)-——)+——)-4y)+4
y 2 y2
plz mark me as brainliest :)
The answer is b, hope I helped :)
Answer: A and B
<u>Step-by-step explanation:</u>
Here is Pascal's Triangle:
Row 1 (x + y)⁰ 1
Row 2 (x + y)¹ 1 1
Row 3 (x + y)² 1 2 1
Row 4 (x + y)³ 1 3 3 1
Row 5 (x + y)⁴ 1 4 6 4 1
∵
Row n (x + y)ⁿ⁻¹ 1 (sum of 2 digits above) 1
C and D are false. A and B are the only correct answers
6:50 is the answer! Hope this helps. You can figure this out by crossing out the ones you KNOW are factors of 4 and 20. And 6:50 is NOT a factor of them . Hope this helped!!
