Answer:

y = 4x +b

Step-by-step explanation:

The question asks you to write in slop intercept form which is y = mx+b so first you ahve to solve for the slope (m) and the formula for that is m = y2-y1/x2-x1

and bascially you plug in any points that are on the table and use the y's and x's

so im going to use the first two points

m = (11-7) / (2-1)

= 4 / 1

= 4

so the slope equals four and we can plug that into our slope intercept equation

y = 4x + b and now we need to slove for b the y intercept and we can do that by plugging in any points from the table into our equation (to understand why this works probaly ask you teacher for a in-depth explination)

im going to use the first points again and plug it into our equation

7 = 4(1) + b (mutiply 1 by four)

7 = 4 +b (isolate b so subtract four from each side)

-4 -4

3 = b so we now know the slope and the y intercept so our equation in slope intercept form will be y = 4x +3

What is the sum of an infinite geometric series if the first term is 156 and the common ratio is 2⁄3?

Zanzabum

Answer:

Step-by-step explanation:

We have

$a_1=156,\ r=\dfrac{2}{3}$

If |r| < 1, then the formula of a sum of an infinite geometric sequence is:

$S=\dfrac{a_1}{1-r}$

Substitute:

$S=\dfrac{156}{1-\frac{2}{3}}=\dfrac{156}{\frac{1}{3}}=156\cdot\dfrac{3}{1}=468$

Y= 3x-1 2x+6=y substitution method

vfiekz [6]

Answer: (7, 20)

Concept:

There are three general ways to solve systems of equations:

Elimination
Substitution
Graphing

Since the question has specific requirements, we are going to use substitution to solve the equations.

Solve:

Given equations

y = 3x - 1

2x + 6 = y

Substitute the y value since both equations has isolated [y]

2x + 6 = 3x - 1

Add 1 on both sides

2x + 6 + 1 = 3x - 1 + 1

2x + 7 = 3x

Subtract 2x on both sides

2x + 7 - 2x = 3x - 2x

$\boxed{x=7}$

Find the value of y

y = 3x - 1

y = 3(7) - 1

y = 21 - 1

$\boxed{y=20}$

Hope this helps!! :)

A basin is filled by two pipes in 12 minutes and 16 minutes respectively. Due to the obstruction of water flow after the two pip

olasank [31]

Answer:

The time duration of the two pipes restricted flow before the flow became normal is 4.5 minutes

Step-by-step explanation:

The given information are;

The time duration for the volume, V, of the basin to be filled by one of the pipe, A, = 12 minutes

The time duration for the volume, V, of the basin to be filled by the other pipe, B, = 16 minutes

Therefore, the flow rate of pipe A = V/12

The flow rate of pipe B = V/16

Due to the restriction, we have;

The proportion of its carrying capacity the first pipe, A, carries = 7/8 of the carrying capacity

The proportion of its carrying capacity the second pipe, B, carries = 5/6 of the carrying capacity

Whereby the tank is filled 3 minutes after the restriction is removed, we have;

$\dfrac{7}{8} \times \dfrac{V}{12} \times t + \dfrac{5}{6} \times \dfrac{V}{16} \times t + \dfrac{V}{12} \times 3 + \dfrac{V}{16} \times 3 = V$

Simplifying gives;

$\dfrac{(2\cdot t +7) \cdot V}{16} = V$

2·t + 7 = 16

t = (16 - 7)/2 = 4.5 minutes

Therefore, it took 4.5 seconds of the restricted flow before the the flow of water in the two pipes became normal
