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.

Solve the equation t/4 = 16

Answers

First you do you opposite of dividing because of the 4 dividing the t. Since the opposite of division is multiplication you multiply and the 4's cancel each other out. So now you have t=16 but what you do to one side you do to the other so you have to * 4 the 16 giving you 64. so now you have 4 = 64. To check you have to divide 64 by 4 giving you 16 once more showing its correct.

t = 4 * 16;
t = 64;

The solution is correct because 64 / 4 = 16;

The length of the hypotenuse of a right triangle is 20 feet and the length of one leg is 16 feet find the length of the other leg

Answers

This is a problem for which you will have to use the Pythagorean theorem.

The Pythagorean theorem states that:

x^2 + y^2 = h^2

where x and y are the legs, and h is the hypotenuse.

Let h = 20 ft, and x = 16

16^2 + y^2 = 20^2

Now, solve for y.

256 + y^2 = 400.
256 - 256 + y^2 = 400 - 256
y^2 = 144
y = 12

The length of the other leg is 12 feet.

Which function equation represents the table? A. f(x) = -x + 2
B. f(x) = -3x + 2
C. f(x) = 2x + 3
D. f(x) = 3x + 2

Answers

The answer is D. f(x) = 3x+2

This is because this is the ONLY function equation that works for ALL of the ordered pairs listed in the table

-4 = 3(-2) + 2
-4 = -6 +2
-4 = -4

-1 = 3(-1) +2
-1 = -3 +2
-1 = -1

2 = 3(0) + 2
2 = 0 + 2
2 = 2

5 = 3(1) + 2
5 = 3 + 2
5 = 5

8 = 3(2) +2
8 = 6 +2
8 = 8
