Answer:

-4y - 7

Step-by-step explanation:

Combine like terms. Note that there is one term with a variable (y), and two constant terms. Combine the constant terms. Note that one positive and one negative sign will result in a negative sign:

-4 + (-3) = -4 - 3 = -7

-4y - 7 is your answer.

The correct scientific notation for the number 500.0 is

marishachu [46]

Answer:

The correct scientific notation for the number 500.0 is $500=5.0\times10^2$

Step-by-step explanation:

While writing a large number in scientific notation we do below mentioned two things.

We take any number between 1 and 10
Then we multiply this number with an exponent of 10.

Hence, any number in scientific notation is in the form $a\times10^b$

Here a is any number between 1 and 10.

b is exponent of 10.

Now, writing 500 in scientific notation, we take a = 5

Hence, we have to take b = 2, since 5 multiplied by 100 equas 500.

Thus, we have

$500=5.0\times10^2$

LekaFEV [45]

Answer:

15.7 units

Step-by-step explanation:

AB = 6, BC = 3

Therefore by Pythagoras theorem

AC = $\sqrt{45}$

$perimeter \: of \: \triangle \: ABC \\ = 6 + 3 + \sqrt{45} \\ = 9 + 6.70820393 \\ = 9 + 6.7 \\ = 15.7\: units$

Can someone help with this

Gelneren [198K]

An equation of the form y = mx + b represents a linear function where m is the slope and b is the y-intercept. For example, y = 3x + 4 represents the linear function whose slope is 3 and whose y-intercept is 4.

Hope this helps!!! The reason why I asked which unit & lesson it is from, is because Idk if you go to k12 or not, by the pic, it looks like you do go to k12... IF you go to K12, I could tell you the answers, that's if I took that lesson... And that's if you'd tell me... Hope I make since.... Ok bye!!! :)
