Plzzzz help with I and j

Mathematics

I: a triangle has a total of 180 degrees. So, we can find the other angle in the triangle by subtracting 180-110= 70 degrees. A straight line has a total of 180 degrees, also. So we can set up another equation that says 180=2m+70. When we simplify, we get 110=2m. Solve, and we get m=55.
J: we can do the same thing in reverse. A straight line has 180 degrees. So we can find the unlabeled angle in the triangle by solving 180=120+a. a=60. Then, we also know that the sum of the angles in the triangle is 180. So, we can set up the equation 180=60+5x. Subtract 60 from both sides and get 120 is 5x. Divide by x, and you get x=24.

What is the value of (f-g)(7)?<br>f(x)=2+x;g(x)=x^2+5<br>(f-g)(7)=[1]​
Sav [38]

Answer:

Alright so on this type of problem you just perform the operation they ask for, which in this case is subtraction.  

Your first step will be to set up the problem:

f(x) - g(x)

Next you will substitute in your values:

(2x + 1) - (x2 - 7)

The easiest way to do the subtraction problems is to distribute your negative into your second set of parenthesis, so your expression would become:

2x + 1 - x2 + 7

Then combine your like terms:

2x - x2 + 8

Lastly put your expression in standard form (highest exponent to lowest)

-x2 + 2x + 8

Hope this helped!

Find the Average Rate of Change between the values of [0, 1]
e-lub [12.9K]

Answer:

The average rate of change cover the given interval is -6

Step-by-step explanation:

The average rate of change of a function over a range can be calculated by;

f(b) - f(a)/b-a

f(b) and f(a) refers to the respective y values of the x values a and b

Since we have a and b, we can get f(a) and f(b) from the plot

From the graph, since a = 0, f(a) is the y-intercept = 6

b = 1

f(b) = 0

So we have the slope as

= (0-6)/(1-0) = -6/1 = -6
