Answer:

y²-3y+2=0

=> y²-(2+1)y +2=0

=> y²-2y-y+2=0

=> y(y-2)-1(y-2)=0

=> (y-2)(y-1)=0

=> y = 2 or y= 1

The equation of a line is -2x6y=-18. find the slope and the y-intercept. Then use them to graph the line.

Vaselesa [24]

Answer:

Slope= $\frac{1}{3}$ and Y intercept=-3

Step-by-step explanation:

-2x + 6y = -18

Simplifying the equation,

6y = 2x - 18

$y=\frac{x}{3}-3$

A general line can be written as,

y=mx + c

, m= Slope of the line

c=y intercept of the line

Y intercept is basically the point where the line intersects, the y axis or the line x=0.

Therefore, from the above data m= $\frac{1}{3}$

and Y intercept= -3.

How does knowing 1/5 of 10 help you find 3/5 of 10? Draw a picture to explain your thinking.

Alborosie

Answer:

If the problem is,

$\frac{1}{5}\text{ of }10$

By finding it,

Take a 5 box grid in which each box represents 1 unit,

Then take 1 box of this grid,

Repeat this step,

Finally, Add them,

We get,

A grid having 10 boxes with 2 taken boxes,

Thus, $\frac{1}{5}\times 10=2$

When we do these steps for three grids we will get $\frac{3}{5}\times 10$ ,

That is, by multiplying the result of $\frac{1}{5}\times 10$ by 3 we will obtain $\frac{3}{5}\times 10$

$\frac{3}{5}\times 10=3\times (\frac{1}{5}\times 10)=3\times 2=6$

An investor invested a total of $2500 in two mutual funds. One fund earned a 5% profit while the other earned a 3% profit. If th

7nadin3 [17]

Answer:

$500 and $2000

Step-by-step explanation:

Let x represent the total investment = $2500

also, this total is split into two different funds

Lets represent these funds as a and b, such that fund a yields a profit of 3% and fund b yield a profit of 5%

So,

a + b = x

a + b = 2500 ......eq 1

Profit from each fund gives;

0.03 a + 0.05b = 115 ....eq 2

Solve simultaneously using substitution method

From eq 1;

b = 2500 - a

Slot in this value in eq 2

0.03a + 0.05 (2500 - a) = 115

expand

0.03a + 125 - 0.05a = 115

collect like terms

0.03a - 0.05a = 115 - 125

-0.02a = -10

Divide both sides by -0.02

a = $500

Put this value of a in eq 1

500 + b = 2500

Subtract 500 from both sides

b = 2500 - 500

b = $2000
