What is the y-intercept when a line has a slope of 1/2 and passes
through the point (2, -1)?

Answers

Answer:

Step-by-step explanation:

You called this question to the right person. To find the y-intercept, you must do the formula of Point Slope (y-y1 = m (x-x1)) Since 2, is x1 and the -1 is y1, we must lay the equation out like this: y - -1 = m (x-2). Next, we must distribute the slope to the x and the 2, which would allow the x, to fit in with the slope, and the 2 to become 1 since 1/2 x 2 is 1. Now what we need to do is get rid of the -1, so what we do here is add 1. And algebra golden rule, whatever you do to one side, you must do to the other side. This would leave y = 1/2x + 2 And therefore 2 is your y-intercept, since it's at the last part of the equation.

Which of the following is the solution of 0.125x+1-0.25x<-3

Answers

Step-by-step explanation:

To find the solution to the inequality 0.125x + 1 - 0.25x < -3, we can simplify and solve for x.

0.125x + 1 - 0.25x < -3

Combining like terms:

-0.125x + 1 < -3

Subtracting 1 from both sides:

-0.125x < -4

Now, to isolate x, we divide both sides by -0.125. However, since we are dividing by a negative number, we need to reverse the inequality sign:

x > -4 / -0.125

Simplifying the division:

x > 32

Therefore, the solution to the inequality 0.125x + 1 - 0.25x < -3 is x > 32.

How do you create a system of inequalities with given restraints?The assignment says:
Julia is deciding how many batches of sugar cookies and how many loaves of banana bread to make. Construct a system of linear inequalities that shows how many batches of sugar cookies (x) and loaves of banana bread (y) she can make with the flour she has but also reflects the fact that she can’t produce negative goods. There are 36 cups of flour available; to make one batch of sugar cookies, Julia needs 2 3/4 cups of flour, and to make one loaf of bread she needs 2 1/2 cups of flour.

Answers

Given:
sugar cookies = x = 1 batch = 2 3/4 cups of flour
loaves of banana bread = y = 1 loaf = 2 1/2 cups of flour

2 3/4 x + 2 1/2 y < 36

the total number of cups of flour used per batch of sugar cookies and loaf of banana bread should not exceed 36 cups of flour.
