When the second number in the ordered pair, b, is not equal to 0, the ratio is expressed as a/b.

Flora needs 3 bags of dog food.

When the second number in the ordered pair, b, is not equal to 0, the ratio is expressed as a/b.

An equation in which two ratios are made equal is known as a percentage.

As an illustration, you could express the ratio as 1: 3 if there is 1 guy and 3 girls.

Given,

Dog eats 2 cups in a day

There are 24 cups in each bag

Solution:

Dog eats one bag of food in  24 cups/2 cups = 12 days

One food bag is sufficient to feed the dog for 12 days

For 35 days, the number of food bags needed is

1/x = 12/35 where x be the number of food bags needed for the dog.

x = 2.92  

That is 3 bags of dog food are needed for 35 days to feed the dog.

The value of x from the given equation is 9/2

The given equation is

log₂(2x - 1) = 3

The general form of logarithm with base 2 is

          log₂ N = x

Conversion of the logarithm to exponential form is

            2ˣ = N

where x is the log₂ of N

           x is the number of times number '2' should be multiplied by intself to obtain n

Using this conversion in the above equation,

log₂(2x - 1) = 3

       (2x - 1)  = 2³    

       (2x - 1)  = 8

        2x - 1 = 8

Given the equation 13.25y = 79.5, the value of y is A. 6.00.

An equation is a mathematical statement that states that two mathematical expressions are equal in value.

Equivalent values are also expressed as algebraic equations sharing the same root.

We depict equations by using the equation symbol (=).

13.25y = 79.5

y = 6 (79.5/13.25)

Check:

13.25y = 79.5

13.25(6) = 79.5

{(-9,3), (8,7), (-9, -9), (2, 4)}

=======================================================

Explanation:

To find an example of a non-function, we look for (x,y) points where x repeats itself. That occurs in choice D where we have (-9,3) and (-9,-9) in the same function set.

The input x = -9 leads to multiple outputs y = 3 and y = -9 simultaneously. This is not allowed if we wanted a function.

A function is only possible if each input x leads to exactly one y output.

So this is why we look for repeated x values when trying to find non-functions. Choices A, B and C all have unique x values that don't repeat, which means those choices represent functions.

Side note: The y values can repeat, but the function won't be one-to-one.

From the given figure < BAC = 180 - ( < ABC + < BCA ) because they are sum of angles in a triangle

given data

< ABC = 52 degrees

< BCA = 88 degrees

calculation for angle BAC

< ABC + < BCA + < BAC = 180 degrees ( sum of angles in a triangle )

< BAC = 180 - ( < ABC + < BCA )

< BAC = 180 - < ABC - < BCA

plugging in the values gives

< BAC = 180 - 52 - 88

Answer:

Equation of line is given as y = mx + c, where m is the slope and c is the y-intercept.

First find the slope.

Formula for slope is given as (y2-y1)÷(x2-x1) or (y1-y2)÷(x1-x2).

Slope = (7-1)÷(-9-9)

= -6/18

= -1/3

Equation of line is y = -1/3 + c.

Substitute either one of the points into the equation to find c.

1 = -1/3(9) + c

c = 4

Hence equation of line is y = -1/3x + 4

After solving the question using Pythagoras' theorem we get, The ladder moving down the wall at 8 feet per second.

According to the question,  

The bottom(base) of the ladder is 12 feet,

the height of the ladder is 13 feet.

Now, We have to find the top of the ladder moving down the wall

by using Pythagoras' theorem,

hypotenuse ^2 = base^2 + perpendicular ^2

13^2 = x^2 + y^2

169 =  x^2 + y^2

After using Pythagoras' theorem

we have this equation and now we will differentiate both sides:  

0  =2x*dx/dt + 2y*dy/dt    

0  =24*1 + 3* dy/dt  

dy/dt = - 8 feet per second

Step-by-step explanation:

f(x} = 3x + 1

g(x} = 2x -- 3

f(g(x)) = 3x + 1. (Calm down right?)

Let the x in the expression be (2x -- 3)

f(g(x)) = 3(2x --3} + 1

Open bracket

f(g(x)) = 6x -- 9 + 1

2... Solve for g(f(x)), using the same strategy

g(f(x)) = 2x -- 3

x = f(x)

Common difference = 2

21st term = 73

Explicit rule : a(n) = 31 + 2n

Three terms in the sequence after 73: 77,77,79

Step-by-step explanation:

Given:

33, 35, 37, 39

If the sequence is arithmetic it  has a common difference ( same difference on each value)

d= Common difference = 35 - 33 = 37 - 35 = 39 - 37 = 2

d = 2

Explicit formula:

a(n) = a1 + d (n - 1 )

Where:

a1= first term = 33

d = common difference = 2

Replacing:

a(n)= 33 + 2 (n - 1 )

a(n) = 33 + 2n - 2

a(n) = 31 + 2n

21st term:

a(21) = 31 + 2 (21) = 31+ 42 = 73

To obtain the three terms in the sequence after 73, add the common difference 3 times.

73 + 2 = 75

75+2= 77

77 + 2 = 79

The evaluated value of the function is as follows:

The functions can be evaluated as follows:

To evaluate a function is to replace (substitute) its variable with a given number or expression.

In other words, evaluating a function means to substitute a variable with its given number or expression.

Therefore,

g(x) = -3x + 1

f(x) = x² + 7

h(x) = 12 / x

j(x) = 2x + 9

Hence,

a.

g(10) = -3(10) + 1

g(10) = -30 + 1

g(10) = - 29

b.

f(3) = (3)² + 7

f(3) = 9 + 7

f(3) = 16

c.

h(-2) = 12 / -2

h(-2) = -6

d.

j(7) = 2(7) + 9

j(7) = 14 + 9

j(7) = 23

e.

h(a) = 12 / a

h(a) =  12 / a

f.

g(b) + g(c) = -3(b) + 1 + -3(c) + 1

g(b) + g(c) = -3b + 1 - 3c + 1

g(b) + g(c) = -3b - 3c + 2

h.

find x when g(x) = 16

16 = -3x + 1

16 - 1 = -3x

15 = -3x

x = 15 / -3

x = -5

j.

find x when h(x) = -2

-2  = 12 / x

-2x = 12

x = 12 / -2

x = -6

k.

find x when f(x) = 23
