Answer:

AC intersect with DR at A

Step-by-step explanation:

v(x) = y = -3/4x - 1/3

y + 1/3 = -3/4x

x = -4/3 × (y + 1/3)

you see ? we only need to show how we calculate x out of y (instead of the normal direction of y or of x).

and to follow naming standards we now simply switch x and y, so that the inverse function is indeed again a function of x

y = -4/3 × (x + 1/3) = -4x/3 - 4/9

Answer: 7.5 (h)

Step-by-step explanation:

Let say

a the outflow of the first pipe

b the outflow of the second pipe

T the volume of the tank.

x the time for filling with the second pipe

two pipes can fill a tank in 3 hours: a*3+b*3=T

One pipe alone can fill the tank in 5 hours : a*5=T

3*b=T -3a ==> 3b= 5a*3a=2a

b=2a/3

b*x=T ==> 2/3*a*x=T ==> 2/3*T/5*x=T ==> 2/15*x=1

x=15/2 = 7.5 (hours)

Answer:

d = 3

Step-by-step explanation:

(7d+3)/4 = 6

Multiply each side by 4

(7d+3)/4*4 = 6*4

(7d+3) = 24

Subtract 3 from each side

7d+3-3 = 24-3

7d = 21

Divide by 7

7d/7 = 21/7

d = 3

Answer:

= 3.65.

Step-by-step explanation:

You know that Tom has 23 coins in total. That means the number of dimes and the number of quarters equals 23.

D + Q = 23

You also know that the total value of the coins is $3.65. A dime is worth $0.10 and a quarter is worth $0.25, so:

0.10*D + 0.25*Q = 3.65

That says that 10 cents per dime times the number of dimes, plus 25 cents per quarter times the number of quarters is three dollars and sixty-five cents.

So you have a system of linear equations:

D + Q = 23

0.10D + 0.25Q = 3.65

I'm going to multiply the bottom row by 100 to clear the decimals.

D + Q = 23

10D + 25Q = 365

Now I can multiply the top row by -10 to eliminate the D terms

-10D - 10Q = -230

10D + 25Q = 365

________________

0D + 15Q = 135

15Q = 135

Q = 9

Tom has 9 quarters.

If D + Q = 23, and Q = 9, then:

D + 9 = 23

D = 14

Tom has 14 dimes.

Always good to double check:

9 quarters is worth $2.25. 14 dimes is worth $1.40. These should sum to $3.65.

2.25 + 1.40

Answer:

C.

Step-by-step explanation:

An equation is an identity if the equation is always true regardless of what value you replace 'x' with.

This means we need to simplify the equations above to see which one will be true for any value of 'x'.

After simplifying equation C, we get -12-8x = -12-8x. Since both sides of the equation are the same, this equation will be true regardless of what value replaces x so this equation is an identity.

Answer:

x = -12.

Step-by-step explanation:

Number in the square next to  5 =  3+x.

Number to the right of this one = x + 1

From left to right the umbers in the second row = 5 + 3 + x

and 3 + x + x + 1

= x + 8 and 2x + 4.

So x + 8 + 2x + 4 = 2x

so 3x + 12 = 2x

x + 12 = 0

x = -12.

[tex]\boxed{\sf a_n=\dfrac{a_{n-1}}{10}\times 4,n\gt 1}[/tex]

Lets verify

[tex]\\ \sf\longmapsto a_2=\dfrac{a_1}{10}\times 4[/tex]

[tex]\\ \sf\longmapsto a_2=\dfrac{500}{10}\times 4=50(4)=200[/tex]

And

[tex]\\ \sf\longmapsto a_3=\dfrac{a_2}{10}\times 4[/tex]

[tex]\\ \sf\longmapsto a_3=\dfrac{200}{10}\times 4=20(4)=80[/tex]

And

[tex]\\ \sf\longmapsto a_4=\dfrac{a_3}{10}\times 4[/tex]

[tex]\\ \sf\longmapsto a_4=\dfrac{80}{10}\times 4=8(4)=32[/tex]

Hence verified

Lets predict next term

[tex]\\ \sf\longmapsto a_5=\dfrac{a_4}{10}\times 4[/tex]

[tex]\\ \sf\longmapsto a_5=\dfrac{32}{10}\times 4=3.2\times 4=12.8[/tex]

Answer:

x = 19.6

Step-by-step explanation:

If we need to find the value of x then first we need to

(7x-25) + (3x +9) = 180  (angles at the same side of transversal will be equal to 180 degree )

10x -16 = 180

10x = 180 +16

10x = 196

x = 196/10

x = 19.6
