[tex] \boxed{(x - a)(x - b) = 0}[/tex]

The equation above is the intercept form. Both a-term and b-term are the roots of equation.

[tex]x = - \frac{1}{3} \\ x = 5[/tex]

These are the roots of equation. Therefore we substitute a = - 1/3 and b = 5 in the equation.

[tex](x + \frac{1}{3} )(x - 5) = 0[/tex]

Here we can convert the expression x+1/3 to this.

[tex]x + \frac{1}{3} = 0 \\ 3x + 1 = 0[/tex]

Rewrite the equation.

[tex](3x + 1)(x - 5) = 0[/tex]

Simplify by multiplying both expressions.

[tex]3 {x}^{2} - 15x + x - 5 = 0 \\ 3 {x}^{2} - 14x - 5 = 0[/tex]

Answer Check

Substitute the given roots in the equation.

[tex]3 {(5)}^{2} - 14(5) - 5 = 0 \\ 75 - 70 - 5 = 0 \\ 75 - 75 = 0 \\ 0 = 0[/tex]

[tex]3( - \frac{1}{3} )^{2} - 14( - \frac{1}{3}) - 5 = 0 \\ 3( \frac{1}{9} ) + \frac{14}{3} - 5 = 0 \\ \frac{1}{3} + \frac{14}{3} - \frac{15}{3} = 0 \\ \frac{15}{3} - \frac{15}{3} = 0 \\ 0 = 0[/tex]

The equation is true for both roots.

Answer:

The fourth once

Step-by-step explanation:

Step-by-step explanation:

We have 2x + 6y = 22.

When x = 5,

=> 2(5) + 6y = 22

=> 10 + 6y = 22

=> 6y = 12

=> y = 2.

Hence y = 2 when x = 5.

Answer:

r = -189

Step-by-step explanation:

multiply both sides by 9 to get rid of the fraction.

-117=r+72

now subtract 72 from both sides.

-117-72=r

r = -189

Answer: π(10^2)(10) −  1/3π(10^2)(10)

Step-by-step explanation:

Container A is a cylinder so the equation is π(r^2)(h)

Container B is a right cone so that equation is 1/3π(r^2)(h)

You would plug in the numbers and then subtract A from B

The formula to find volume of cylinder of container A is πr²h - 1/3π²h.

Thus Option (c) is correct

The volume of cylinder is "the density of the cylinder which signifies the amount of material the cylinder can carry".

According to the question,

Container A is "cylinder with a cylinder of radius of 10 units and has height is 10 units. Container B is cylinder with a cylinder of radius of 10 units and has height is 10 units. A right cone has base and has a height 10 units.

In order to find volume of container A only if subtract volume of cone from volume of cylinder

Formula for volume of cylinder = πr²h

Formula for volume of cone = 1/3π²h

Formula for volume of container A = πr²h - 1/3π²h

Hence, the formula to find volume of cylinder of container A is  πr²h - 1/3π²h. Thus, Option (c) is correct

a. 48

So first, the ratio we know is 5:4 which in other words is 5x:4x. We also know that there are 60 clownfish. So that means 5x = 60 --> x = 12. So then 4x has to equals 12 x 4 which is 48.

b. 36

So first, the ratio we know is 4:3 which in other words is 4x:3x. We also know that there are 48 angelfish. So that means 4x = 48 --> x = 12. So then 3x has to equals 12 x 3 which is 36.

Answer:

x = 5/3

10 - 5 = 5

3x = 5

x = 5/3 or 1 2/3

Answer:

51

Step-by-step explanation:

Let x be the number

When x divided by 5 then it gives remainder 1 and when divided by 12 gives remainder 3.

We have to  the value of x.

Using Euclid's algorithm

[tex]a=bq+r[/tex]

Where [tex]0\leq r<b[/tex]

[tex]x=5q+1[/tex]

[tex]x=12p+3[/tex]

[tex]5q+1=12p+3[/tex]

[tex]5q-12p=3-1[/tex]

[tex]5q-12p=2[/tex]...(1)

When q=10 and p=4

Then,

[tex]5(10)-12(4)=50-48=2[/tex]

q=10 and p=4 satisfied the equation (1)

Substitute q=10

[tex]x=5(10)+1=51[/tex]

Hence,51 is  the least counting number  which when divided by 5 gives the remainder of 1 and when divided by 12 gives us the remainder of 3.
