Variable y varies directly with variable x, and y = 6 when x = 9. What is the value of x when y = 18?

Answers

Answer 1

Answer: Well, 18 is 6 x 3

Since y was multiplied by 3, we can multiply x by 3 to get its value

9 x 3 = 27

Answer 2

Answer: (9)(6)=(x)(18)
54=18x
3=x

What two numbers multiply to 18 but add to get -5?

Answers

so this one has to be two negative numbers to get a positive number. so then you can think of what multipys to 18
-9*-2 wont work because -9+-2 gets you -11
-6*-3 wont work because -6+-3 gets negative nine
i dont think there is one honestly. ive sat here and tried them all
2 and 9 6 and 3 and 18 and 1

Final answer:

To find two numbers that multiply to 18 and add to -5, consider the factors of 18 and check which pair meets the conditions. The numbers that satisfy the given conditions are -9 and -2.

Explanation:

To find two numbers that multiply to 18 and add to -5, we can use the factoring method. By considering all the possible factors of 18, we can find the pair of numbers that satisfy the given conditions. The two numbers that meet these criteria are -9 and -2.(-9 * -2 = 18, -9 + -2 = -11)

What is the value of 3-(-2)?

Answers

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

When subtracting a negative number, you will add it.

This is because the negative signs of the subtraction sign and the negative number will cancel out.

This will change the subtraction sign to a positive sign and will switch the negative sign on the number to a positive one.

So, 3 - (-2) will change to 3 + (2)

3 + 2

= 5

Which represents the solution(s) of the system of equations, y = x2 – x + 1 and y = x? Determine the solution set by graphing.(1, 1)
(0, 1) and (1, 1)
(0, 0) and (1, 1)
no solutions

Answers

Answer:

$(1,1)$

Step-by-step explanation:

we have

$y=x^(2)-x+1$ -------> equation A

$y=x$ -------> equation B

we know that

The solution of the system of equations is the intersection points both graphs

using a graphing tool

see the attached figure

The intersection both graphs is the point $(1,1)$

therefore

the solution is the point $(1,1)$

What is the slope-intercept form of the function that contains the point (1, –2) and has a slope of –3?Y= __ x + __

Answers

Well, from the info given, you cannot automatically put it into slope intercept form. You have to put it into point slope form first and then convert it.

Point slope form looks like this: y - y1 = m(x - x1)

Now, with the info it looks like this: y - (-2) = -3(x - 1)

Now you distribute and change the - (-2) to +2 (because subtracting a negative is the same as adding a positive) and you get: y + 2 = -3x - 3

Now, you subtract 2 to get y by itself (we are converting now)

y = -3x - 5
