For the example you gave of m+83, you would just write it out, like "m plus eighty three"

It's teaching you how to interpret word problems by having you convert the expression to words you may see in a problem. This expression may be seen in a word problem as "the sum of a number and eighty three".

G(x)= 81-3x? <br> what are the x and y intercepts?

mel-nik [20]

Answer:

x - intercept : (27,0)

y- intercept : (0,81)

Step-by-step explanation:

$g(x)=81-3x$

you can rearrange the right side to make the equation look like y=mx+b

$g(x)=-3x+81$

According to y=mx+b, b is the y-intercept

∴ (0,81) is the y-intercept of the equation

To find the x-intercept, plug in 0 for y and solve for x

$g(0)=-3x+81\\-81 = -3x\\x = 27$

∴ (27,0) is the x-intercept of the equation

I WILL GIVE BRAINLIEST Suppose that is $1200 initially invested in an account at a fixed interest rate, compounded continuously.

lbvjy [14]

<h3>Answer: 2.93</h3>

Note: The percent sign is already taken care of.

=====================================================

Explanation:

The continuously compounded interest formula is

$A = Pe^{rt}\\\\$

where,

A = 1431 = account balance t years into the future
P = 1200 = deposit
e = special constant roughly equal to 2.718
r = unknown interest rate and what we want to find
t = 6 years

Since the unknown variable r is in the exponent, we'll need logs to solve it. A handy phrase is "if the exponent is in the trees, log it down to find it". By "log it down" I mean in terms of lumber, and not a journal.

We could use any base logarithm, but it's handy to use the special base 'e' log. This is the natural logarithm abbreviated as Ln.

---------------

Solving for r involves these steps

$A = Pe^{rt}\\\\1431 = 1200*e^{r*6}\\\\e^{6r} = 1431/1200\\\\e^{6r} = 1.1925\\\\6r = \text{Ln}(1.1925)\\\\r = \frac{1}{6}*\text{Ln}(1.1925)\\\\r \approx 0.02934199063006\\\\r \approx 0.0293\\\\$

Move the decimal over 2 spots to the right to convert 0.0293 to 2.93%

This is the same as multiplying by 100.

You can just look the answer up on safari or google don’t bother putting it on here because it takes 5 months to get a reply and when you do it’s me saying you should look it up but you don’t feel like it so your grade suffers
