Answer:

y=-4x

Step-by-step explanation:

WE need to write the equation for the given graph

In the graph y intercept is (0,0)

The equation of linear graph is y=mx+b

where m is the slope and b is the y intercept

From the given graph y intercept is 0 so b=0

to find slope pick two points from the graph

(0,0) and (1, -4)

slope = $\frac{y_2-y_1}{x_2-x_1} = \frac{-4-0}{1-0} = -4$

m=-4 and b=0

So the equation becomes

y= -4x+0

y= -4x

|13x-4|+12 < 56 Anybody know this cuz I do

Ronch [10]

Answer:

$\displaystyle x\in \left(-\frac{40}{13},\frac{48}{13}\right)$

Step-by-step explanation:

Inequalities with Absolute Value

We must recall the following rule:

$\text{If }|M|0$

Then:

$-N$

We have the following inequality:

$|13x-4|+12 < 56$

Subtracting 12:

$|13x-4|< 56-12$

$|13x-4|< 44$

Applying the rule:

$-44$

Adding 4:

$-44+4$

Operating:

$-40$

Dividing by 13:

$\displaystyle -\frac{40}{13}$

The solution expressed in interval form is:

$\boxed{\displaystyle x\in \left(-\frac{40}{13},\frac{48}{13}\right)}$

a woman had 75 to give away she gave the first person 1/3 of it then the second person 1/5 of the balance hiw much money did she

HACTEHA [7]

75 divided by 3 is 25, so she gave the first person 25. 75 divided by 5 is 13 for the second person. 13 + 25 is 38, and 75 - 38 is 37, so she had $37 left. Hope this helps!

solmaris [256]

Answer:

Equation for cost of the hall restoration fee 70.4 + 52.8 + 11f = 128 .15 and the cost of the hall restoration fee is $0.45 .

Step-by-step explanation:

Let us assume that the hall restoration fee be f .

As given

The ticket price for a concert at a historic music hall includes.

$6.40 for the concert $4.80 for the program and a hall restoration fee the price for 11 tickets is$128.15 .

Than the equation becomes

(Cost for concert + Cost for program + Hall restoration fee) × Number of tickets = Total amount of 11 tickets

Putting all the values in the above

(6.40 + 4.80 + f) × 11 = 128.15

Open the bracket

6.40 × 11 + 4.80 × 11 + 11f = 128.15

70.4 + 52.8 + 11f = 128 .15

11f = 128 .15 - 123.2

11f = 4.95

$f = \frac{4.95}{11}$

f = $ 0.45

Therefore the equation for cost of the hall restoration fee 70.4 + 52.8 + 11f = 128 .15 and the cost of the hall restoration fee is $0.45 .
