a line with a slope of 1 passes through the point (14,11) . What is the equation in slope intercept form

Mathematics

timurjin [86]3 years ago
7 0

Answer:

y-11 = -x + 14

Step-by-step explanation:

The quickest way to a proper equation here is to use the point-slope form:

y-k = m(x-h).  Here x = 14 and y = 11, so:

y-11 = -1(x-14), or y-11 = -x + 14.

In slope-intercept form, that'd be y = -x + 25.

Convert 29.5% to a decimal
cricket20 [7]
Whatever% of anything is just (whatever/100) * anything.

thus 29.5% of something, is just (29.5/100) * something, and the decimal form of 29.5% is just 29.5/100 or the quotient of 29.5÷100.

Tim is investigating the relationship between the number of years since a tree was planted and the height of the tree in feet. H
wolverine [178]

Answer: There is not a good prediction for the height of the tree when it is 100 years old because the prediction given by the trend line produced by the regression calculator probably is not valid that far in the future.

Step-by-step explanation:

Years since tree was planted (x) - - - - height (y)

2 - - - - 17

3 - - - - 25

5 - - - 42

6 - - - - 47

7 - - - 54

9 - - - 69

Using a regression calculator :

The height of tree can be modeled by the equation : ŷ = 7.36X + 3.08

With y being the predicted variable; 7.36 being the slope and 3.08 as the intercept.

X is the independent variable which is used in calculating the value of y.

Predicted height when years since tree was planted(x) = 100

ŷ = 7.36X + 3.08

ŷ = 7.36(100) + 3.08

y = 736 + 3.08

y = 739.08

Forward prediction of 100 years produced by the trendline would probably give an invalid value because the trendline only models a range of 9 years prediction. However, a linear regression equation isn't the best for making prediction that far in into the future.

Find the measure of the missing angles.
Alenkinab [10]

Answer:

d = 69°, e = 32°, f = 79°

Step-by-step explanation:

the 69° angle and d are vertical angles, so d is 69°.

same with e and the 32° angle, so e is 32°.

the 69° angle and f are on a straight angle, which means they, and e, add up to 180° when combined.

69 + 32 = 101

180 - 101 = 79

so f is 79°.
