Answer and Explanation:

Well since it's just basic graphing, all you have to do is plot the points. The graph counts by 2, so -7 will be in between -6 and -8. Then, since the next number is positive, you will need to count up 7 spaces from that point, (so that your final point in up 7 spaces from -7 spaces) Hope that made sense!

-4(11x+2)=80<br> Solve for x

jek_recluse [69]

Answer: x=-2

Step-by-step explanation:

To solve for x, we want to isolate x.

-4(11x+2)=80 [distribute]

-44x-8=80 [add both sides by 8]

-44x=88 [divide both sides by -44]

x=-2

Now, we know that x=-2.

To find the product of (−2√20k)(5√8k3), first write using a single radical. Which expression is equivalent to the given product?

ad-work [718]

Answer:

Assuming the variable is included under the radical,

-40k²√(10)

Step-by-step explanation:

$(-2\sqrt{20k})(5\sqrt{8k^3})$

First we will simplify the first factor,

$-2\sqrt{20k}$

We will write 20 as a product of factors:

$-2\sqrt{4*5k}$

We know the square root of 2 is 2, so we pull a 2 out:

$-2(2)\sqrt{5k}\\\\=-4\sqrt{5k}$

Now we will simplify the second factor,

$5\sqrt{8k^3}$

We will rewrite 8 as a product of factors, as well as the variable:

$5\sqrt{2*4*k^2*k}$

The square root of 2 is 2, so we pull a 2 out. Additionally, the square root of k² is k, so we pull that out:

$5(2)(k)\sqrt{2k}\\\\=10k\sqrt{2k}$

This gives us the product

$(-4\sqrt{5k})(10k\sqrt{2k})$

Multiplying the coefficients, we have

$-4(10k)(\sqrt{5k})(\sqrt{2k})\\\\=-40k(\sqrt{5k})(\sqrt{2k})$

Multiplying the two radicals, we have

$-40k\sqrt{5k*2k}\\\\-40k\sqrt{10k^2}$

The square root of k² is k, so we pull a k out, leaving

$-40k(k)\sqrt{10}\\\\=-40k^2\sqrt{10}$

Can someone help me with this?

yulyashka [42]

Answer:

Step-by-step explanation:

We need to find the error first.

We can do this by subtracting, to find the difference

2.4-1.9 = 0.5

the difference, or error, is 0.5

Now we find a percentage that describes how much more 2.4 is than 1.9

We can create an equation to solve this

2.4 = 1.9 Times x

Now we need to find the value of x

x= 1.2632

now we double check

1.9 Times 1.2632 = 2.4

Now we round to a whole number

1.2632 = 1

To convert a number to a percentage, you need to bring the number over a decimal point.

so 1 becomes .1, or 10 percent
