\text {Slope = } \dfrac{6-1}{7+3} = \dfrac{5}{10} = \dfrac{1}{2}

Equation: y = 1/2 x + b

<u>Find y-intercept:</u>

At (7, 6),

6 = 1/2 (7) + b

<span>6 = 3.5 + b

b = 2.5

Equation: y = 1/2 x + 2.5

Answer: </span>y = 1/2 x + 2.5

NEED HELP FAST!!! Find the percent of increase from 260 to 430. Round to the nearest tenth of a percent if necessary.
a_sh-v [17]

You started out with 260, and increased to 430.
The amount you increased was (430 - 260) = 170

170 is  (170/260) = <em>65.4%</em> of what you started with.

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

Another way:

The new amount is  (430/260) of the old amount.

 430 / 260 = 1.654 = 165.4%

The original amount was  260.
You started with  100%  of it.
You ended up with  165.4%  of it.
That's an increase of  65.4% .

Solve the following function for y when x=5 round to the nearest tenth
Wittaler [7]

In the given question , we have a function given , which is

y= 13(0.5^x)

And we need to find the value of y when x=5.

So we substitute 5 for x and solve for y, that is

y=13(0.5^5) = 0.40625

And on rounding to the nearest tenths, we will get

y=0.4

So when x=5, y=0.4

The graphs of functions f(x) and g(x) = f(x) + k are shown below:<br><br> What is the value of k?
KatRina [158]

Answer:

k = 4

Step-by-step explanation:

k is the difference of y-intercepts (where the lines intersect with the y-axis). So, subtract the y-intercept of f(x) from the y-intercept of g(x).

2 - (-2) = 4

Hope that helps! :D
