Answer:

I don't know the answer, but i know how to solve it. you have to do y/x to find the slope. One equation could be y=mx=b. Or y=mx. Or ax+by=c. then plot your points and replace m and b with the right coordinates.

Answer:

y= -7x+35

Step-by-step explanation:

so if we write the equation in y- intercept form its <u><em>y=mx+b</em></u> with m slope and b the intercept. so if we plug in the things we know, it becomes -7=-42+b. we solve this to get that b is 35 to make this equation work. now we know the equation, which is y= -7x+35

If f(x) = (x + 9 and g(x) = --6, which describes the range of (f + g)(x)?

S_A_V [24]

Given:

Consider the below figure attached with this question.

To find:

The value of $(f+g)(x)$ .

Solution:

The given functions are:

$f(x)=|x|+9$

$g(x)=-6$

Now,

$(f+g)(x)=f(x)+g(x)$

$(f+g)(x)=|x|+9+(-6)$

$(f+g)(x)=|x|+9-6$

$(f+g)(x)=|x|+3$

We know that,

$|x|\geq 0$

Adding 3 on both sides, we get

$|x|+3\geq 0+3$

$(f+g)(x)\geq 3$

So, $(f+g)(x)\geq 3$ for all values of x.

Hence, the correct option is A.

Put the expression (48c)^3/4 in radical form hurry plz

Svet_ta [14]

Remember that if something is raised to a fraction exponent, the denominator of the fraction is the radical and the numerator stays a power. So it becomes:

fourth root of (48c)^3

Joint Frequency because of the fact that it "joins" one number from the column(up and down) and one from the row(side-by-side), hence the two-way table.
