Which equation represents a line that has a slop of 3/4 and passes through the point (2,1)??

Veronika [31]

Answer:

(B) 4y = 3x-2

Step-by-step explanation:

Divide by the coefficient of y to see the slope. It will be the resulting coefficient of x. Only choices B and D match requirements.

Check to see which equation is satisfied by the given point:

B: 4(1) = 3(2) -2 . . . . true

D: 4(1) = 3(2) +5 . . . .false

The appropriate equation is ...

4y = 3x-2

A farmer has chickens and cows. You ask the farmer how many chickens he has, and how many cows he has. The farmer has 28 healthy

crimeas [40]

Set the number of chickens as x and number of cows as <span>y
</span>so the farmer has total 28 animals
so x+y=28
you know that since the animals are healthy
chickens will have 2 legs and
cows will have 4 legs
the total number of legs are 64
so 2x+4y=64
since you want to find the number of cows
so from the first equation <span>x+y=28
</span>we will get another equation <span>x=28-y
</span>then plug into <span>2x+4y=64
2(28-y)+4y=64
56-2y+4y=64
56+2y=64
-56 -56
2y=8
y=4

The points G(1, 4) and H(3, 0) are on a coordinate plane. What is the approximate distance between points G and H?

oksano4ka [1.4K]

Then the approximate distance between the points is 4.47 units.

<h3>What is the approximate distance between points G and H?</h3>

We have the points G(1, 4) and H(3, 0), to get the distance between them we use the distance formula, we will get:

$D = \sqrt{(1 - 3)^2 + (4 - 0)^2} \\\\D = \sqrt{(-2)^2 + (4)^2}\\\\D = \sqrt{4 + 16} = \sqrt{20}$
