Answer:

25

Step-by-step explanation:

Let us assume that m<1 nad m<2 are supplementary. Since the sum of supplementary angles is 180degrees, hence;

<1 + <2= 180

123+2x+7 = 180

130+2x = 180

2x = 180 - 130

2x = 50

x = 50/2

x = 25

Hence the value of x is 25

Which function below is the inverse of f(x) = x^2-9
USPshnik [31]
To find the inverse
replace f(x) with y
switch all x and y
solve for y
replace y with f⁻¹(x)

f(x)=x^2-9
y=x^2-9
x=y^2-9
x+9=y^2
sqrt both sides
\sqrt{x+9}
replace
f⁻¹(x)=\sqrt{x+9}

that is the inverse

1.Jessica lost some of her money. She found 3/6 of it. What fraction of her money is still missing ?
notsponge [240]
Hey there!

1.
If Jessica found 3/6 of her money, half of it is still missing.

This is because 3/6 = 1/2, so Jessica also found half of her money and is missing half of it.

2.

16 ounces = 1 pound

16 ounces * 10 pounds = 160 <------

If the baby weighs 10 pounds, he weighs 160 ounces.

Hope this helps you.
Have a great day!

B(n)=1 (-2) n-1 what is the fourth term
sveta [45]

Answer:

b(4) = -8

Step-by-step explanation:

We are to find the 4th term.

n = 4

b(n) = 1(-2)ⁿ⁻¹

b(4) = 1(-2)⁴⁻¹

b(4) = 1(-2)³

b(4) = 1(-8)

b(4) = -8

Which statement describes the graph of function g compared to function f?
emmasim [6.3K]

Answer: OPTION B.

Step-by-step explanation:

Below are some transformations for a function f(x):

1. If f(ax) and a>1, the function is compressed horizontally by a factor of \frac{1}{a}.

2. If f(ax)  and 0, the function is stretched horizontally by a factor of \frac{1}{a}.

3. If bf(x) and 0, the function is compressed vertically by a factor of "b".

4. If bf(x)  and b>1, the function is stretched vertically by a factor of "b".

In this  case you have the function f(x):

f(x)=6^{x-2}

And the function g(x):

g(x)=0.4(6)^{x-2}

So, you can identify that:

g(x)=bf(x) and  0

Therefore, the graph of the function g(x) is a vertical compression of the graph of function f(x).
