1 a) so you’re solving multi-step equations so you should add 3x and 4x together to make 7x and then you can minus the 5 on the left side so then you have to subtract 5 from the other side as well so then it’d be 7x=14 and then you dive 7/7 and that leaves you with one or just x and then you have to divide 14 by 7 because you did that with the left side so now you’re finished and the answer is x=2

What are the zeros of 3x²(x+π)³(x-4)²
Aneli [31]
Hi again!

The zeros are the values of x. This is where the graph intersects the x - axis. In order to find the zeros, replace y with 0 and solve for x.

The answer is x = 0, -π, 4

I am not sure what grade are you or the level, but for me, they sometimes asked me to find their multiplicities as well

The multiplicity of a root is the number of times the root appears.

So, the answer are
x = 0 and the multiplicity of 2
x = -π and the multiplicity of 3
x = 4 and the multiplicity of 2

Good luck with your studies!

Please help!! Please give step by step so i can understand
miss Akunina [59]

Answer:

p = - 14

Step-by-step explanation:

Using the rules of exponents

a^{m} ÷ a^{n} = a^{(m-n)}

(a^{m}) ^{n} = a^{mn}

Note 81 = 9² and 729 = 9³

Given

(81)^{-4} ÷ (729)^{2-p}

= (9^{2}) ^{-4} ÷ (9^{3}) ^{2-p}

= 9^{-8} ÷ 9^{6-3p}

= 9^{-8-(6-3p)}

= 9^{-8-6+3p}

= 9^{3p-14}

Thus

9^{3p-14} = 9^{4p}

Since bases on both sides are equal then equate the exponents

4p = 3p - 14 ( subtract 3p from both sides )

p = - 14

Line passes through point (1, 7) and point (-2, 4). What is the slope of this line?
Drupady [299]

The slope of the line is 1.

The slope of the line is 1 because the line moves ror goes up from left to right, making it a positive. The line also moves one block over and one block up.
