olive's garden in only 10y2 and the watermelon plants she wants to grow required 2.5y2 each.how many watermelon plants can she g
DerKrebs [107]

Answer:

4 plants

Step-by-step explanation:

In this problem, we are given the total area of the garden, which is:

A=10y^2

The number of plants that can fit inside the garden is given by the equation:

A=na

where:

n is the number of plants

a is the area of each plants

In this problem, the area of each plant is

a=2.5y^2

Therefore, we can re-arrange the equation to find the number of plants that can fit:

n=\frac{A}{a}=\frac{10}{2.5}=4

What is the equation of the line that passes through (4, -1)
Mekhanik [1.2K]

Answer:

Step-by-step explanation:

answer: y = -5 + 19

We can use the point-slope formula to find an equation to solve this problem. The point-slope formula states: (y−y1)=m(x−x1)

Where m is the slope and (x1y1) is a point the line passes through.

Susbtituting the slope and values from the point from the problem gives:

(y−−1)=−5(x−4)

(y+1)=−5(x−4)

We can also solve this for the slope-intercept form. The slope-intercept form of a linear equation is: y=mx+b

Where m is the slope and b is the y-intercept value.

Substitute the slope from the problem for m and the values of the point from the problem for x and y and solve for b:

−1=(−5⋅4)+b

−1=−20+b

20−1=20−20+b

19=0+b

19=b

We can substitute for m and b in the formula to find the equation:

y=−5x+19

Im a lil stuck on this :v
12345 [234]

Answer:

C-----> x<-7

Step-by-step explanation:

first u do this to turn x in positive and consequently change the > to an <:

(-1).(-4x)>28.(-1)

so:

4x<-28

x<-7

# when multiplying each side by (-1), you have to change the symbol (>) to an (<), or (<) to an (>)
