The value of the expression is 252
Step-by-step explanation:
The expression that we have to evaluate in this problem is
And we have toe valuate it for
x = 3
y = 4
In order to evaluate the expression, let's substitute the values of x and y into it:
First, we calculate the square of 3, which is:
Substituting into the expression,
Now we multiply everything and we get:

1.
The formula of a slope (m):
We have the points (7, 8) and (3, 10). Substitute:
2.
a) point-slope form:
Substitute:
b) slope-intercept form:
Answer:
y = -2x + 9
Step-by-step explanation:
The general shape of the equation is y = ax + b, you just have to find a and b.
b is simple, it is the y coordinate where the line crosses the y axis, i.e., b=9.
a is the slope of the line. This is the change in y when you take one step to the right. The change is -2.
Hence y = -2x + 9
Hey there!
If you ever see the word "is" in a story problem, it means that there is an equal sign there. Let's apply that to this.
23800 =(is) 0.34i (income)
Now, we can solve for i by dividing.
23800/0.34= 70,000
Therefore, the annual income is $70,000.
I hope this helps! Have a great day!
