Answer:

Number of followers liked latest post = 360

Second model represent the problem.

Step-by-step explanation:

let,

Number of followers liked latest post = x

Total number of followers = 600

According to given condition;

x = 60% of 600

x= (60/100)600

x = 360

Number of followers liked latest post = 360

Second model represent the problem.

i am thinking of 2 numbers when i add my numbers the answer is 1 when i multiply my numbers the answer is 0.09 what is the numbe

Virty [35]

X + y = 1.....x = 1 - y
x * y = 0.09

y(1 - y) = 0.09
y - y^2 = 0.09....re-arrange
y^2 - y + 0.09 = 0
(y - 0.9)(y - 0.1) = 0

y - 0.9 = 0 x + y = 1
y = 0.9 x + 0.9 = 1
x = 0.1

y - 0.1 x + y = 1
y = 0.1 x + 0.1 = 1
x = 0.9

so ur 2 numbers are : 0.1 and 0.9

Find an equation of the line that is parallel to the graph of 2x+3y=5 and contains the point (3, −1).

uranmaximum [27]

Answer:

A) Equation of line is 3X - 2Y = 11

B) Equation of line is Y = X + 1

C) Equation of line is Y - 7 = 0

Equation of line , point (3 , -1) and slop $\frac{3}{2}$ is 3X - 2Y = 11

Step-by-step explanation:

Given equation of line as 2x + 3y = 5

slove of this line (m1) = - $\frac{2}{3}$

Now another line passes through point (3 , -1) having slop (m2)

Both lines are parallel to each other, i.e (m1) × (m2) = - 1

So slop of second line (m2 ) = $\frac{-1}{m1}$

(m2) = $\frac{-1}{(\frac{-2}{3} } )$

(m2) = $\frac{3}{2}$

Now eq of line with point (3 , -1) and slop (m2)

Y- y1 = (m2)( X - x1)

Or, Y +1 = $\frac{3}{2}$ (X - 3)

i.e 2Y + 2= 3X - 9

∴ Equation of line is 3X - 2Y = 11 Answer

B) Given points as ( 5,6) and (3 , 4)

Slop (m) = $\frac{y2 - y1}{x2 - x1}$ = $\frac{4 - 6}{3 - 5}$ = 1

So the equation of line is

Y- y1 = (m)( X - x1)

Y - 6 = (1) (X - 5)

i.e Equation of line is Y = X + 1 Answer

C) Given points as ( 0, 7) , (0 , -8)

Slop (m) with co-ordianate = $\frac{y2 - y1}{x2 - x1}$

Or, = $\frac{-8 - 7}{0 - 0}$

Hence equation of line is Y - 7 = 0 Answer

Kirk and his family decide it is more reasonable for him to attend the local community college. they want to save for the cost o

Pani-rosa [81]

If you would like to know which is the most reasonable goal for Kirk and his family to plan to save, you can calculate this using the following steps:

a. $225 a month * 2 years * 12 months = 225 * 2 * 12 = $5400
b. $200 a month * 3 years * 12 months = 200 * 3 * 12 = $7200
c. $100 a month * 4 years * 12 months = 100 * 4 * 12 = $4800
d. $75 a month * 5 years * 12 months = 75 * 5 * 12 = $4500

The most reasonable goal to plan to save would be goal b, because $7200 is more than <span>$6845.</span>

PLEASE HELP!!!! WILL GIVE YOU BRAINLIEST!!

borishaifa [10]

The graph means that 2 x and 9.4 make up 20 in total, so set up the equation 2x + 9.4 = 20.

Subtract 9.4 from both sides.
