Step-by-step explanation:

Answer:

Undefined

Step-by-step explanation:

To find slope, you need the difference of y over the difference of x.

For example, let's use (-8,8) and (-8,3).

Difference of y: 8-3

Difference of x: -8-(-8) (Note that the order of the x values must be the same as the order of the corresponding y values of the coordinate)

(8-3)/(-8+8)

= 5/0

Now, we see that we have to divide by 0, except it's impossible to divide by 0, so the slope is left as undefined.

Taylor can clean 625 pools in 25 hours

If Taylor can clean pools at a constant rate of 25 pools per hour, this is expressed as:

25 pools = 1hour

We are to calculate the number of pools that Taylor can clean in 25 hours, this is expressed as;

x = 25 hours

Divide both expressions

25/x = 1/25

x = 25 * 25

x = 625 pools

Hence Taylor can clean 625 pools in 25 hours

Answer:

The answer is 46.

Step-by-step explanation:

First, you will have to add up both functions in order to find the new expression for (g + f)(a) :

g(a) + f(a) = (g + f)(a)

(g + f)(a) = 3a + 3 + 2a - 2

(g + f)(a) = 5a + 1

Next, you have to substitute a = 9 into the function :

(g + f)(9) = 5(9) + 1

(g + f)(9) = 46

Answer:

5 days

Step-by-step explanation:

The question above is modeled by the equation :

150 − 8x = 170 − 12x.

After how many days will both have ye same amount :

Number of days = x

Collect like terms

-8x + 12x = 170 - 150

4x = 20

x = 20/4

x = 5 days

The boys will have the same amount in their account after 5 days.

Answer:

x= 2

Step-by-step explanation:

y = 7 means it is parallel to the x axis . so the perpendicular line is to be parallel yo the y axis. .

so the equation is to be like x = c

but it is passing (2,13)

so the equation is

x= 2

Step-by-step explanation:

Proportional Variables

Two variables x,y are proportional if one of them can be calculated as the other variable time a fixed constant:

y = k.x

Or, equivalently:

k = y/x

k is called the constant of proportionality.

The table gives three points: (13,45.5) (14,49) (15,52.5)

To find out if the values correspond to a proportional relationship, we find the value of k for each pair:

k = 45.5 / 13 = 3.5

k = 49 / 14 = 3.5

k = 52.5 / 15 = 3.5

Since the value of k is the same for all the points, we conclude the table shows a direct proportional relationship and the constant of proportionality is 3.5

Answer:

~10525.41 after 7 years

Step-by-step explanation:

y=a(1+r)^x

That's the equation for exponential growth

a= the starting amount

r= the rate at which it is growing

x=years

with that information

a=7000

r=6% or 0.06

so y=7000(1+0.06)^x -> y=7000(1.06)^x

x=7

y=7000(1.06)^7

y~10525.41

Answer:

x=14

Step-by-step explanation:

Hope This Helps!

Answer:

x = 22/3, x=14

Step-by-step explanation:

Start by isolating whatever is in the absolute value sign; in this case divide either side by 4

4|1-3/4x + 7| =10,

-----------------   ----

        4            4

|1-3/4x + 7| = 10/4 = 5/2,

now if we apply the absolute value rule we know that 1-3/4x + 7 will be equal to -5/2, and 5/2

1-3/4x + 7 = 5/2 and 1-3/4x + 7 = -5/2

-3/4x + 8 = 5/2,

-3/4x=5/2-8,

-3/4x = 5/2-16/2,

-3/4x = -11/2,

x = -11/2*-4/3 = 44/6 = 22/3

-3/4x+8 = -5/2

-3/4x = -5/2-8

-3/4x = -5/2-16/2

-3/4x = -21/2

x = -21/2*-4/3 = 82/6 = 14

Answer:

try 3 i need 20 more letters

Answer:

f(x) = 2x^2 + 12x +10

Step by step solution:

x = 1 x = 5 y = 10

f(x) = a(x+1)(x+5)

f(0) = a(1)(5) = 10

5a = 10

Divide by 5

a = 2

f(x)= 2(x+1)(x+5)

f(x) = 2(x^2 +6x +5)

f(x) = 2x^2 + 12x +10

Answer:

The length of the base will be: 17 m

Step-by-step explanation:

Given the area of the triangle

[tex]A=102\:m^2[/tex]

Using the formula of Area of a triangle:

[tex]A=\frac{1}{2}\left(b\times h\right)[/tex]

Here,

As the base of a triangle is 7 less than twice its height.

so

[tex]b=2h-7[/tex]

so the formula of Area of a triangle becomes

[tex]102=\frac{1}{2}\left(\left(2h-7\right)\times \:h\right)[/tex]

[tex]204=h\left(2h-7\right)[/tex]

[tex]2h^2-7h=204[/tex]

[tex]2h^2-7h-204=0[/tex]

[tex]\left(2h+17\right)\left(h-12\right)=0[/tex]

[tex]2h+17=0\quad \mathrm{or}\quad \:h-12=0[/tex]

[tex]h=-\frac{17}{2},\:h=12[/tex]

As height can not be negative, so:

[tex]h=12[/tex] m

Hence, the length of the base:

[tex]b=2h-7[/tex]

   [tex]= 2(12)-7[/tex]

    [tex]=24-7[/tex]

     [tex]= 17[/tex] m

Therefore, the length of the base will be: 17 m
