Maya is estimating the product of 88 and 12. Which statements are true? Check all that apply.

1 answer:

7 0

Answer:

If she rounds 88 to the nearest hundred and 12 to the nearest ten, her estimate will be 1,000 because if you take 88x12, your answer is 1056. so knowing that the closest answer to 1056 is 1000 not 900.

Hope it helped!

What is the equation of the line that is parallel to the line 5x + 2y = 12 and passes through the point (-3, 2)

qwelly [4]

2y = 12 - 5x
y = 6 - 5/2x

2 = -5/2(-3) + b
2 = 15/2 + b
2 - 15/2 = b
b = -11/2

y = 15/2x - 11/2

Which equation has a constant of proportionality equal to 9 y=81/3x y=9x y=3x y==1/9x

aev [14]

Answer:

B) y = 9 x has Proportionality Constant = 9

Step-by-step explanation:

Two quantities P and Q are said to be PROPORTIONAL if and only if:

P ∝ Q ⇔ P = k Q ⇔ $k = \frac{P}{Q}$

Here, k = PROPORTIONALITY CONSTANT

Given : k = 9

Now, let us consider the given expressions in which x ∝y

y = 81/3 x

Here, $\frac{y}{x} = \frac{81}{3} = 27 \ne 9$

So, here Proportionality Constant ≠ 9

y = 9 x

Here, $\frac{y}{x} = 9$

So, here Proportionality Constant = 9

y = 3 x

Here, $\frac{y}{x} = 3 \ne 9$

So, here Proportionality Constant ≠ 9

y = 1/9 x

Here, $\frac{y}{x} = \frac{1}{9} \ne 9$

So, here Proportionality Constant ≠ 9

Hence, only y = 9 x has Proportionality Constant = 9
