Answer:

y = 2x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2, then

y = 2x + c ← is the partial equation

To find c substitute (4, 3) into the partial equation

3 = 8 + c ⇒ c = 3 - 8 = - 5

y = 2x - 5 ← equation of line

Step-by-step explanation:

Given:

The graphs of two parabolas.

To find:

The equation of the quadratic function with given graphs.

Solution:

(a)

The factor form of a parabola is

[tex]y=a(x-b)(x-c)[/tex]

Where, a is a constant, b and c are x-intercepts.

From the graph (a) it is clear that the graph intersect the x-axis at -1 and 3. So, b=-1 and c=3.

[tex]y=a(x-(-1))(x-3)[/tex]

[tex]y=a(x+1)(x-3)[/tex]            ...(i)

Put x=0 and y=3 because the y-intercept is (0,3).

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

[tex]3=-3a[/tex]

[tex]\dfrac{3}{-3}=a[/tex]

[tex]-1=a[/tex]

Putting a=-1 in (i), we get

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

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

Therefore, the equation of the parabola is [tex]y=-(x+1)(x-3)[/tex].

(b)

The vertex form of a parabola is

[tex]y=a(x-h)^2+k[/tex]

Where, a is a constant and (h,k) is vertex.

From the the graph (b), it is clear that the vertex of the of the parabola is at point (2,0) and y-axis is (0,8). So, h=2, k=0.

[tex]y=a(x-2)^2+0[/tex]

[tex]y=a(x-2)^2[/tex]            ...(ii)

Put x=0 and y=8 because the y-intercept is (0,8).

[tex]8=a(0-2)^2[/tex]

[tex]8=4a[/tex]

[tex]\dfrac{8}{4}=a[/tex]

[tex]2=a[/tex]

Putting a=2 in (ii), we get

[tex]y=2(x-2)^2[/tex]

Therefore, the equation of the parabola is [tex]y=2(x-2)^2[/tex].

Answer:

1. $165

Step-by-step explanation:

Zahra will expect to earn 14 *t +25 in a day on which she waits on "t" tables.

A linear function in mathematics is one that has either one or two variables and no exponents. It is a function with a straight line as its graph.

Given, Zahra is a waitress at a restaurant. Each day she works, Zahra will make a guaranteed wage of $25,

Let "t" be the tables Zahra is waitressing.

Since, she will get about $14 in tips for each table she waits on.

Total additional tip = t * 14

guaranteed wage = 25$

So, Total Zahra will earn for waitressing on "t" tables = 14 *t +25

For t = 10 tables

Zahra will earn for waitressing on 10 tables = 14 * 10 +25

Zahra will earn for waitressing on 10 tables = 165

Therefore, Zahra will expect to earn $165 in a day on which she waits on 10 tables.

Step-by-step explanation:

Answer:

i think its -5

Step-by-step explanation:

if you devide 25 by -5 you get -5

Answer: x = -5

Step-by-step explanation:

We can use inverse operations to solve the equation. Because the term "-5x" is multiplication (because you are multiplying x by -5), we can use division to solve the equation.

First, we will divide -5 from 25.

25 ÷ -5 = -5.

Because of this, x = -5!

If we're not sure, we can also check the equation.

-5 x -5 = 25, so the answer is true.

In conclusion, x = -5!

Answer: The sale price of the chair including tax = $221.83

Step-by-step explanation:

Regular price of chair = $435

Discount = 47%

Sales price = 47 % of (Regular price)

= $ 0.47 (435)

= $ 204.45

Tax rate = 8.5% = 0.085

Tax amount = Tax rate × Sales price

= 0.085 × 204.45

= 17.37825≈ $ 17.38

The sale price of the chair including tax = Sales price + Tax amount

= $ ( 204.45+17.38)

= $ 221.83

Hence, the sale price of the chair including tax = $221.83
