Answer:

y = (1/2)(x) + 1/2

Step-by-step explanation:

The x-intercept is (-1, 0) and the y-intercept appears to be (0, 1/2).

As we go from the x-intercept to the y-intercept, x increases by 1 and y increases by 1/2.  Thus, the slope of the line is m = rise / run = 1/2.

Knowing that m = 1/2 and b = (0, 1/2), we can write the equation of this line in slope-intercept form as

y = (1/2)(x) + 1/2

Answer:

Step-by-step explanation:

1). f(z) = [tex]\sqrt{z-5}[/tex]

   The given function 'f' is defined for (z - 5) ≥ 0

    z ≥ 5

   Therefore, domain of the function will be [5, ∞)

   Or "All real numbers greater than or equal to 5"

2). [tex]f(z)=\frac{1}{z-8}[/tex]

    Domain: "All real numbers except 8."

    Since the given function is not defined for z = 8

3). f(z) = [tex]\sqrt{z}[/tex]

    The given function is defined for every real numbers greater and equal to zero.

    Domain: "All positive real numbers and 0"

4). f(x) = 8x

    This function is defined for all real numbers.

    "Domain: All real numbers"

Answer:

$160

Step-by-step explanation:

100/100 = 100 ÷ 100 = 100% = 1. Multiply a number by the fraction 100/100

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

The company payment is $1440.

Carol's total cost is $610.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Cost of the bill = $2,050

Company payment = 80% of the bill less the deductible

This means,

80/100 x 2,050 = 1640

Company payment.

= 1640 - 200

= $1440

Now,

Carol's total cost.

= 2,050 - 1440

= $610

Thus,

The company payment is $1440.

Carol's total cost is $610.

Answer:

10 + (2 x 3)^2 / 4 x (1/2) ^3

First do the parentheses

2 x 3 = 6

1 / 2 = 0.5

We are left with

10 + 6^2 /4 x 0.5^3

Do exponents

6 x 6 = 36

0.5 x 0.5 x 0.5 = 0.125

10 + 36 / 4 x 0.125

Divide by 4 and multiply by 0.125

36 / 4 = 9

9 x 0.125 = 1.125

We are left with

10 + 1.125 = 11.125

The answer is 11.125

Step-by-step explanation:

2.07 times 7.50 = $15.57!

The amount of money that he pays for 7.5 pounds of bananas will be $15.525.

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The price of bananas is at a rate of $2.07 per pound. Then the amount of money that he pays for 7.5 pounds of bananas is given as,

⇒ $2.07 x 7.5

⇒ $15.525

Then the amount of money that he pays for 7.5 pounds of bananas will be $15.525.

Answer:D

Step-by-step explanation:

Answer:

10.5

Step-by-step explanation:

Let E be the midpoint of OA  and F be the midpoint of OB. 

If point O is placed between A and B, then points E and F are placed on different sides from O. The segment OE has length 12÷2=6 cm and segment OF has length 9÷2=4.5 cm. Than EF=6+4.5=10.5 cm.

If point O is placed outside the segment AB, then point B is closer to point O than point A, because OA>OB. Since OE=6 cm and OF=4.5 cm, EF=6-4.5=1.5 cm.

If the order of points is A, O, B, then the midpoints of AO and OB will be separated by half the length of AB: (12 cm + 9 cm)/2 = 10.5 cm.

Answer:

all real numbers less than 0

Step-by-step explanation:

In the picture attached, the question is shown.

The function described is an exponential decay with the form:

y = ab^x

where a = 2 and b = 1/4

The range of an exponential decay function is all real numbers greater than 0. This means that after f(x) has been reflected over the x-axis its range is all real numbers less than 0.

Answer:A=6 B=-4.5

Step-by-step explanation:

We want to find the values of A and B such that the given system of equations has no solutions. We will find that the values of A and B can be:

B = -4.5

A = 6

A system of linear equations has no solutions when the lines are parallel (so the lines never do intercept).

Here the system is:

3x + 4y = A

Bx – 6y = 15

Remember that two lines are parallel if and only if they have the same slope and different y-intercept, then let's write both equations in the slope-intercept form:

y = A/4 - (3/4)*x

y = -15/6 + (B/6)*x

So we must have:

B/6 = -3/4

A/4 ≠ -15/6

From the first one we get:

B = (-3/4)*6 = -4.5

From the second one we get:

A  ≠ (-15/6)*4 = -10

Then from the given pairs, the only one that causes the system to have no solutions is:

B = -4.5

A = 6
