2. y - 8 = 15 y -0 =

Mathematics
1 answer:
Wewaii [24]3 years ago
6 0

Answer:

23

Step-by-step explanation:

I'm going to start by solving the first equation like so,

y - 8 = 15        (Remember what we do to one side we MUST do to the other)

<u>  +8    +8 </u>

y = 23

So know we know y = 23  What we have to do now is replace 23 for y in the second equation.

y - 0 = ?

23 - 0 = 23  

Hope that helps and have a great day!

If the fraction 396\x-10 is equivalent to -22. find the value of x.
slavikrds [6]
396/x-10
396/x-10 = -22
Multiply to remove the variable from the denominator. 
x= -8

If you want to check the work do it by adding -8 into the equation as x. 

I hope this helps!

Can someone help? I hate math so much lol I don’t understand
marishachu [46]

Answer:

±6

Step-by-step explanation:

Given the mathematical expression;

√36 < √42 < √49

But, √36 = 6 * 6 = 6²

√49 = 7 * 7 = 7²

Simplifying further, we would substitute the new values respectively;

±[6] < √42 < ±[7]

Therefore, evaluating √36 is equal to ±6.

About 5 out of 10 people entering a community college need to take a refresher mathematics course. If there are 970 entering​ st
Ksenya-84 [330]

Answer:

"6 out of 10 people" means the ratio of class:no_class is 6:4

990/10 = 99, the smallest the "class" and the "no_class" add up to is 10. And, generally, the total divides with that nicely, as in this case.

99(6) = 594 ----------- probably class

99(4) = 396 ------------------ probably no class

Total  = 990

I hope this helps

Which function grows the fastest for large values of x? f(x)=8x f(x)=3x f(x)=4x2+3 f(x)=1.5x 20 points
Aleonysh [2.5K]
The 4 functions are:
f_1 (x) = 8x
f_2(x)=3x
f_3(x)=4x^2+3
f_4(x)=1.5 x

Let's keep in mind that for large values of x, a quadratic function grows faster than a linear function:
ax^2 \ \textgreater \  kx for large values of x

In this problem, we can see that the only quadratic function is f_3(x), while all the others are linear functions, so the function that grows faster for large values of x is
f_3(x) = 4x^2 +3
