Answer:
(-2) and 3.
Step-by-step explanation:
1) if to take two random points on the given line, then A(0;0) and B(1;-2). The required slope is: (-2-0)/(1-0)= -2;
2) like the previous item two points A(0;0) and B(1;3), then the required slope is: (3-0)/(1-0)=3.
Which of the following represents, the difference of a number squared and four is less than or equal to five.
Answers
Answer:
x² - (4 ≤ 5)
Step-by-step explanation:
(I have x representing the number that is squared, it might be a different letter on your options, but regardless it will be the same general answer. You also may not need the parentheses around the 4 ≤ 5)
Difference means subtraction so we know that the second number/group of numbers will be subtracted from the first that is listed.
Next, if you are squaring any number it's going to have the little 2 to the right of it. That's what that means.
Then, we look at that last bit. "Four is less than or equal to five." This means exactly how it sounds. To write this we need the symbol ≤. This symbol means less than or equal to. You would would but the 4 in front and the 5 in back to get 4 ≤ 5.
Now we just put it together. It tells us that 4 ≤ 5 is being subtracted from a number squared. So this means that a number squared needs to be first, and because difference means subtraction, we would subtract 4 ≤ 5 from that. A number squared can be represented by any letter variable, but for this example, I will use x.
This leaves you with x² - (4 ≤ 5)

Write the equation in function form:
8x + 4y = 20
Answers
Writing a an equation in function form is simply expressing y values in terms of x. In other words when you substitute a particular value for x, you get a particular value for y.
so
8x + 4y = 20
4y = 20 - 8x
y = (20-8x)/4 or y = (20-8x)/4 or y = f(x) = 2(10-4x)/4 = (10-4x)/2 = 5 - 2x = -2x+5
check your answer with a sample values say with a point that solves the equation or a point on the line.....see below....
(2,1)
8(2) + 4(1) = 20......16 + 4 = 20...check.......y=-2(2) + 5 = -4 +5 =1....x=2, y=1...checks....so f(x)=-2x+5
another quick check are the intercepts.....y (x=0)....or x (y=0)
8 (0) + 4 (5) = 20.....(0,5).......y=f(x) = -2 (0) + 5...x = 0..y=5 so again the function checks so
8x + 4y = 20.....is also written as the function y= f(x)= -2x + 5

Answer:
300, 80, 3 ( partial quotients)
383 (final quotient)
Step-by-step explanation:
7291 is the dividend
19 is the divisor
we have no quotient, so let us make Q our partial quotients
In step 1: Q = 5700 / 19 = 300
In step 2: Q = 1520 / 19 = 80
In step 3: Q = 57 / 19 = 3
14 Is the final remainder in which it isn't a multiple of 9
therefore the final quotient is adding all the partial quotients quotients in step 1, 2 and 3
300 + 80 + 3 = 383
