Product of a whole number and unit fraction for 3x3/4

Answers

Answer 1

Answer: Because all real numbers can be expressed as fractions, whole numbers can be too, with the denominator as 1.

e.g. 3 = 3/1

And then it works like normal multiplication

3/1 x 3/4 = (3 x 3) / (1 x 4)
= 9/4
= 2 and 1/4

Also for future reference, normally * (the asterix, shift + 8) is used to show multiplication on a computer, because "x" is normally used in algebra to mean something else.

Answer 2

Answer: I believe its 2 and 1/4

Which graph represents the equation y = --3x – 1?

Answers

Answer:

Step-by-step explanation:

Final answer:

The equation y = -3x - 1 represents a straight line with a slope of -3 and y-intercept of -1. The graph will be a line falling to the right and crossing the y-axis at -1.

Explanation:

The question asks which graph represents the equation y = -3x - 1. This is a linear equation, where the coefficient of 'x', -3 here, gives us the slope of the line, and the constant, -1 here, gives us the y-intercept. A slope of -3 means for each step of 1 increase in x, the value of y decreases by 3. The y-intercept is the point where the line intersects with the y-axis, in this case at y = -1.

A graph representing this equation will be a straight line with a slope of -3 (indicating the line falls as we move along the positive x-axis) and will cut the y-axis at y = -1.

An airplane takes off from an airport and travels 1100 miles east and then travels 600 miles north. This trip can be plotted on the coordinate plane, where the airport is the point (0, 0).

Answers

Answer:

The plane is now at (1100, 600) in unit mile

Step-by-step explanation:

The airport is the point (0 ,0) and the plane travels from there 1100 miles east and thereafter 600 miles north. If the unit is in mile then we may say that the planes co -ordinates are now (1100 , 600)

Since,

positive x -axis points towards east and positive y-axis points towards north.

If x=7 and y=-3

12-5xy +9x2y + 15-2y2

Answers

Just plug in x = 7 and y = -3 in place of x and y, respectively

$12-5xy +9x^2y + 15-2y^2\n\n12-5(7)(-3) +9(7)^2(-3) + 15-2(-3)^2\n\n12 - (-105) + (-1323) + 15 -18\n\n12 + 105 - 1323 + 15 - 18 = \boxed{-1209}$

Your answer is -1209
