What is the slope intercept form of -1/2 and 1, -1/2 being the slope??

Mathematics
1 answer:
nevsk [136]3 years ago
7 0
The slope-intercept form of the equation of a straight line is y=mx+b, where m is the slope and b is the y-coordinate of the y-intercept.

If the given slope is -1/2, then this equation becomes y = (-1/2)x + b.

You do not say that b=1.

But if we let b=1, then the equation becomes y = (-1/2)x + 1.

Find x for me i need help.
vesna_86 [32]

Answer:

X is 70 degrees

Step-by-step explanation:

In a triangle, all the angles add up to 180.

We can set up an equation:

48+62+x=180

x=180-(48+62)

x=70

Formulate the situation as a system of inequalities. (Let x represent the number of goats the farmer can raise and y represent t
Firdavs [7]

Answer: He can raise up to 40 goats and 100 llamas.

Step-by-step explanation:

Hi, to answer this question we have to write system of equations with the information given:

The space each goat needs (4) multiplied by the number of goats (x); plus The space each llama needs (10) multiplied by the number of llamas must be less or equal to the acre land available (800)

4x +10y ≤ 800 (acres)

The amount of veterinary care (in $) each  goat needs (110) multiplied by the number of goats (x); plus The  amount of veterinary care   each llama needs (88) multiplied by the number of llamas (y)must be less or equal to the Rancher's budget.(14520)

110x +88y ≤ 14,520 (cost)

Multiplying the first equation by 27.5, and subtracting the second equation to the first one:

110x + 275y ≤22,000

-

110x +88y ≤ 14,520

____________

187y ≤ 7480

y ≤ 7480/187

y ≤ 40

Replacing y in the first equation

4x +10(40) ≤ 800

4x +400 ≤ 800

4x ≤ 800-400

4x ≤ 400

x ≤ 400/4

x ≤ 100

using a regression calculator, what is a good prediction for the height of the tree when it is 100 years old?
mylen [45]

Correct Question:

Tim is investigating the relationship between the number of years since a tree was planted and the height of the tree in feet. His data are shown in the table. Years Since Tree was Planted vs. Height of Tree

Years since the tree was planted, x

Height of tree in feet, y

2, 17, 3, 25, 5, 42, 6, 47, 7, 54, 9, 69

Using a regression calculator, what is a good prediction for the height of the tree when it is 100 years old?

Answer/explanation:

There is no good prediction for the height of the tree when it is 100 years old. If you analyze careful in details the regression calculator you realize that it probably will not valid that far in to the future say 100 years.

Solve the following system of equations using a method of your choice.
dusya [7]

Answer:

Step-by-step explanation:

cant remember what this method is called but

change the second equation to be y = something

x + y = 10

y = -x + 10

plug in this y= in the first equation to get x

4x -2(-x + 10) = 4

4x + 2x -20 = 4

6x = 24

x = 4

then plug in the x we found into the original second equation

4 + y = 10

y = 6

so your ordered pair would be (4,6)

hope this helps <3
