Answer:

y=\frac{1}{2}x-2

Step-by-step explanation:

Perpendicular lines have negative reciprocal gradients(slopes) so the slope of your new line would be 1/2. Then you use the point to find the new y-intercept

y=mx+b

2=\frac{1}{2}(8)+b

2=4+b

B=-2

y=\frac{1}{2}x-2

If f(x)= 3x + 1 and f^(-1)= x-1/3, then the ordered pair of f^(-1)(10)=
iragen [17]

The answer is B

The correct inverse of 3x+1 is actually (1/3)x - 1/3

plug in 10 to the inverse

10/3 - 1/3 = 9/3 or 3

this gives you the point (10,3)

James and Michael are the partners in a local business. They needed $480,000 to start the
larisa [96]

Answer:

James invested $160,000

Step-by-step explanation:

- In total, they needed $480,000 to start the business

- 1:2 ratio means one of them payed double the amount than the other

so the expression would be,

2x + x = 480,000

Let x represent how much they each need to invest

the expression can be simplified to,

3x = 480,000

now you need to get x alone, this would be done be dividing both sides by 3

\frac{3x}{3} = \frac{480,000}{3}\\x = 160,000

James invest $160,000

Michael invest $160,000 x 2 = $320,000

and if you add them together, you get the total amount

$320,000 + $160,000 = $480,000

Let me know if you have any questions !

If f(x)=7-3x and g(x)=3x-7, what is the value of f(1)+g(1)?
kondor19780726 [428]
F(x)=7-3x g(x)=3x-7

First let’s solve for f(1)

f(1)= 7-3(1)

f(1)= 7-3

f(1)= 4 *we will save this for later

Let’s now solve for g(1)

g(1)= 3(1)-7
g(1)= 3-7
g(1)= -4

Now we can find f(1) + g(1)

f(1) =4 and g(1)= -4

4+(-4) = 0
