For function of g,g(0)=1 and g(1)=5 assuming g is a linear function what is g(3)

lawyer [7]

Answer:

$g(3) = 13$

Step-by-step explanation:

Given

$g(0) = 1$

$g(1) = 5$

Required

Find g(3)

Since g(x) is a linear function, then:

$g(x) = mx + c$

For: $g(0) = 1$

$g(x) = mx + c$

$g(0) = m*0 + c$

$1 = 0 + c$

$1 = c$

$c = 1$

For: $g(1) = 5$

$g(x) = mx + c$

$g(1) = m * 1 + c$

$5 = m * 1 + c$

$5 = m + c$

Substitute $c = 1$

$5 = m + 1$

$m = 5 - 1$

$m =4$

So, the function is:

$g(x) = mx + c$

$g(x) = 4x + 1$

Calculate g(3)

$g(3) = 4*3 + 1$

$g(3) = 12 + 1$

$g(3) = 13$

2> -2-c. how would I graph this?

REY [17]

Answer:

-4< c

Step-by-step explanation:

2> -2-c

Add 2 to each side

2+2> -2+2-c.

4 > -c

Divide each side by -1. Remember that dividing by -1 will flip the inequality.

4/-1 < -c/-1

-4< c

Simplify the following <img src="https://tex.z-dn.net/?f=%5Cfrac%7B%20%5Cfrac%7B1%7D%7Bx%7D%20%20%2B%201%20%7D%20%7B%20%5Cfrac%2

Good evening, Riley!

Used properties:

$\star~\boxed{\mathsf{a = \dfrac{ax}{x}, \ \ x\neq 0}}\\ \\ \\ \star~\boxed{\mathsf{\dfrac{\frac{a}{b}}{\frac{c}{d}} = \dfrac{ad}{bc}}}$

Now, note that:

$\mathsf{1 = \dfrac{x}{x},\ x\neq 0}$

So:

$\mathsf{\dfrac{\frac 1 x + \frac x x }{\frac 1 x} = \dfrac{\frac{x+1}{x}}{\frac 1 x}}=} \mathsf{\dfrac{x}{1}\dfrac{x+1}{x} = \boxed{x + 1}}$

Can someone help me round 621x29

wlad13 [49]

Your rounded number is 18010

The reason for this is because when you multiply 621X29, you get 18009. When you round numbers, you want to see how the numbers are. If a number is 4 or below, you will make that number a zero or not count it, whereas numbers above 5 will go up. I hope this helps and if you have any questions, let me know

Suppose you invest $2,500 in a fund earning 10% simple interest annually. After two years you have the option of moving your mon

Anon25 [30]

Answer:

account after 2 years of simple interest at 10%: (2,500 * 0.10 * 2) + 2500 = 3,000

Note that simple interest only pays interest on the original balance, NOT on the accrued (paid) interest....

a) 5 more years at 10% simple: (2500 * 0.10 * 5) + 3,000 = $4,250

5 years compound interest on $3k: 3,000(1.07^5) = $4,207.66

b) TOTAL of 10 years

simple interest: (2500 * 0.10 * 10) + 2500 = 5,000

compound interest: only 8 years remain of the total 10 year time horizon

3000(1.07^8) = $5,154.56
