What is the slope of the graph of 12x + 3y = –17?A.-4


B.negative one-fourth


C.one-fourth


D.4

Answers

Answer 1
Answer: To get the slope you need to solve for y:
12x+3y=-17
Subtract 12x from both sides:
3y=-12x-17
Divide everything by 3:
y=-4x-17/3
The slope is -4.

What is the value of x in the equation 7x 2y = 48 , when y = 3?

Answers

2y will be known as 2(3) since y=3 so it will be 7x times 6 so the. you subtract 6 from both sides and you get 7x=42 the. you divide 7 on both sides and the answer will be 6

What is the value of x in the equation 7x + 2y = 48

Given y=3

We plug in 3 for y and solve for x

7x + 2y = 48

7x + 2(3) = 48

7x + 6 = 48 ( subtract 6 on both sides)

7x + 6 - 6 = 48 -6

7x = 42

Divide by 7 on both sides

x = 6

the value of x = 6

We can say the value of x=6 when the value of y = 3

What is the solution to 2x+12=5x-9

Answers

so 2x+12=5x-9
you want all of the unknowns on one side and all of  the known values on the other or
subtract 2x from both sides
12=3x-9
add 9 to both sides
21=3x
divide both sides by 3
7=x
2x+12=5x-9\ \ \ \ |combine\ like\ terms\n\n2x-5x=-9-12\ \ \ \ \ |simplify\n\n-3x=-21\ \ \ \ \ |:-3\n\nx=7

The radius of a circle is 17 inches . What is the circumference? Use 3.14 for pi!

Answers

Answer:

53.38

Step-by-step explanation:

Final answer:

The circumference of a circle with a radius of 17 inches can be calculated using the formula C=2πr. Substituting these values into the formula gives a circumference of approximately 106.76 inches.

Explanation:

The question is asking about the circumference of a circle, given its radius. The formula to find the circumference of a circle is C=2πr, where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.

In this case, the radius of the circle (r) is 17 inches. Substituting these values into the formula, we get:

C = 2 * 3.14 * 17 = 106.76 inches

So, "the circumference of the circle is approximately 106.76 inches".
