Answer:

The slope is -1/5 and the y intercept is 12

Step-by-step explanation:

Y=-1/5x+12

This is in the form

y=mx+b where m is the slope and b is the y intercept

The slope is -1/5 and the y intercept is 12

Answer:

-1/5 = slope

12 = y-intercept

Step-by-step explanation:

y = mx + b

m is always equal to the slope

b is equal to the y-intercept

which makes -1/5 the slope

and makes 12 the y-intercept

It takes 3 hours to cook an 8-pound turkey. How long would it take to cook a turkey that is 14 pounds? Round to the nearest tent
pochemuha

Answer:

5.3 hours

Step-by-step explanation:

Given:

3 hours = 8lbs. turkey

?? hours = 14lbs. turkey

Do proportions:

\frac{3}{8} = \frac{x}{14}  <-- Cross Multiply

42 = 8x  <-- Solve for x

x = 5.25

Round to the nearest tenth:

x = 5.3 hours

vivado [14]

Answer:

≈ 33°

Step-by-step explanation:

So, first, you can draw a visual. Refer to the image attached below:

Using this info, you can use trigonometric ratios. Recall that:

tangent = opposite side/adjacent side

sine = opposite side/ hypotenuse

cosine = adjacent side/hypotenuse

You can clearly see that you have an opposite side and a given hypotenuse. This means we'll be using sine.

So:

sinX = \frac{150}{275}

However, we're not trying to find sinX, we're trying to find X.

So we would have to use inverse sine, which would then be:

X = sin-1 (\frac{150}{275} )

Put this into your calculator, and:

X ≈ 33.05573115...

Write in slope intercept form an equation of the line that passes through(-4,1), (4,3)
saul85 [17]

Answer:

Step-by-step explanation:

I know this is not your question but it may help

Question:Write an equation in Slope intercept form of the line that passes through the given  points (-3,4) (1,4)

2 Answers:

1: y=x+4

2:

answer would be “y=4”

to find the answer: first you have to find the slope with the given points. (y2 - y1 / x2 - x1)

plug it in to get: (4-4 / 1- -3) = 0/4 = 0

this means the slope would be 0

if the y intercepts are the same then it usually indicates that the slope would be 0 and that the answer is the y intercept.. but if you don’t understand how to get slope-intercept using other coordinates then here’s how:

you can use point-slope formula (y-y1 = m (x-x1) in order to do this just plug in one of the coordinates. in this case an example of point-slope form would be:

y-4 = 0 (x - -3) or y-4 = 0(x-1)

it doesn’t matter which coordinates you use..

then solve the point slope for slope-intercept.

y-4 = 0(x-3) multiply 0 with x and -3

y-4 = 0x move -4 to the right by adding 4

y = 0x + 4 or y = 4 would be your answer!
