Point slope formula is y-y1=m(x-x1)
The slope is -3. So you just plug in what you know which is the (x1,y1). So the point slope form is y+1=-3(x-4).
The slope intercept form is y=mx+b. So you plug in the m,x, and y to solve for b. B is 11. So the slope intercept form is y=-3x+11.

The measures of two complementary angles are described by the expression(13y+12) and (20y+12). Find the measures of angles​
Pachacha [2.7K]

Step-by-step explanation:

complementary angles means that both of them together = 90

13y +12 + 20y + 12 = 90

add all y together and numbers together

33y + 24 = 90

solve for y

33y= 66. y= 2

now let's get the measurements of the angles

13(2) + 12= 38

20(2) + 12= 52

You produce 100 items and 47 of them will be shipped out of state. What percent of the items will be shipped out of state?
larisa [96]
47%.
anything that's out of 100 is going to be that number as a percent.
So if you had 34 things being shipped out of state then 34% of them would be shipped out of state.

I'm having a little bit of trouble figuring out the formula to solve this problem.
goldfiish [28.3K]

Answer:Red price hast he least least cost per gram of apple.

Step-by-step explanation:

1) considering Royal Gala, 75 gram apple cost $0.41

The cost per gram is 0.41/75 = $0.0055

2) considering Honey crisp, 93 gram apple cost $0.82

The cost per gram is 0.82/93 = $0.0088

3) considering Red Prince, 81 gram apple cost $0.36

The cost per gram is 0.36/81 = $0.0044

Since $0.0044 per gram is the lowest of the three, then the type of apple with the least cost per gram is Red prince.
