Reduce 7y + 2y2 - 7 by 3 - 4y.

Mathematics
1 answer:
Liula [17]3 years ago
8 0

Step-by-step explanation:

Reduce = Deduct = Subtract

7y + 2y^2 - 7 - (3 - 4y)

distribute the negative sign outside 3-4y.

7y+2y^2-7 - 3 + 4y

collect like terms, meaning try to make similar components of the equation together at one place.

7y & 4y are like terms in this case.

7y + 4y + 2y^2 - 7 - 3

11y + 2y^2 - 10

rewrite 2y^2 infront of the equation because it has the highest degree which is 2.

2y^2 + 11y - 10

What is the mode of Variable A? Scatter plot on a first quadrant coordinate grid. The horizontal axis is labeled Variable A. The
klemol [59]
Variable A : 1, 2, 4, 4, 5, 6, 7, 9

Mode is the number that appears more frequently in the data set than other numbers.

1, 2, 5, 6, 7, and 9 only appeared once.
4 appeared twice.

So, the mode of the data set is 4.

Additional info:
mean = (<span>1 + 2 + 4 + 4 + 5 + 6 + 7 + 9) / 8 = 38 / 8 = 4.75
median = (4 + 5) / 2 = 9 / 2 = 4.5
range = 9 - 1 = 8</span>

Identify BR rounded to the nearest tenth. HELP PLEASE!!
ahrayia [7]

Answer:

<h2>BR ≈ 49.0</h2>

Step-by-step explanation:

Use cosine:

cosine=\dfrac{adjacent}{hypotenuse}

We have

adjacent=42\\hypotenuse=BR\\\alpha=31^o

\cos31^o\approx0.8572

Substitute:

\dfrac{42}{BR}=0.8572

\dfrac{42}{BR}=\dfrac{8,572}{10,000}          <em>cross multiply</em>

8,572BR=420,000                <em>divide both sides by 8,572</em>

BR=\dfrac{420,000}{8,572}

BR\approx49.0

MrRa [10]

Answer:

What's 2.54 cm in inches?

To convert cm to inches, divide your cm figure by 2.54 or multiply it by 0.3937. As an example, let's say you have a piece of wood measuring 50cm and you want to convert it into inches. To get your answer, divide your cm figure by 2.54. So, 50 ÷ 2.54 = 19.685 inches.
