Answer:

In order to be a linear function, a graph must be both linear (a straight line) and a function (matching each x-value to only one y-value).

Step-by-step explanation:

I hope this helps, sorry if it doesn't good luck

It is false that Every relation that is linear, must also be a function.

Given that,
A statement is to be justify that, whether is true and false that Every relation that is linear, must also be a function.

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.

Linear functions are defined as functions whose graph is a straight line. A linear function has the following form. example f(x) = 1 + 2x. A linear function has only independent variable and only a dependent variable.

Let's understand with an example,
If y = 1 *[tex]x^0[/tex] , is a linear function but it's a verticle straight line. for every value of x, y is independent of x so for the function it is necessary that the function should be consist of an independent variable and a dependent variable,
Implies every function that is linear must not also a function.

Thus, It is false that Every relation that is linear must also be a function.

a) d + f

b) 3d + f - 7

c) d + f + 25Step-by-step explanation:

Answer:

(x+5) (x+9)

Step-by-step explanation:

In order to the trinomial

x

Begin by finding the factors for the first term

x

=

x

⋅

x

Place those factors as the first term in each parenthesis

(

x

(

x

)

Since both signs of the trinomial are positive you will be adding the factors and both signs will be positive.

(

)

Now determine the factors of the third term

45

=

1

⋅

45

,

3

⋅

15

,

5

⋅

9

We need the factors that will add up to the middle term

14

=

5

+

9

Place these factors as the second term in each of the parenthesis.

(

x

+

5

)

(

x

+

9

)

(x-5)(x-9) is the factored form of the expression  x²-14x+45

The given expression is x²-14x+45

x is the variable in the expression

x square minus forteen times of x plus forty five

Plus and minus are operators in  the expression

x²-9x-5x+45

Now let factor out the expression

x(x-9)-5(x-9)

(x-5)(x-9)

Hence, the factored form of the expression is (x-5)(x-9)

Can you explain a faster way to do this problem rather than figuring out the grams of protein per dollar for each one? Thank you!

The graph above shows the amount of protein

supplied by five different food products, A, B, C, D,

and E, as a percentage of their total weights. The

costs of 10 grams of products A, B, C, D, and E are

$2.00, $2.20, $2.50, $4.00, and $5.00, respectively.

Answer:

Step-by-step explanation:

Given the decimal number 7.7592

The value of the 7 in the ones place is 7 tens i.e 10

The value of 7 in the tenths place is 7 tenth i.e 7/10 = 7 * 1/10. The value of 7 in the tenths place is 1/10 = 0.1

Comparing both values

We will compare both values by finding their ratios as shown;

ratio = value of the 7 in the ones place/value of the 7 in the tenth place

ratio = 10/0.1

ratio = 100

Since the ratio is 100, this means that "the value of the 7 in the ones place is 100 times the value of the 7 in the tenths place"

Answer:

17/15

Step-by-step explanation:

Sec A = 1/ Cos A

Cos A = Adjacent / Hypotenuse

1/Cos A = Hypotenuse / Adjacent

So, Sec A = Hypotenuse/Adjacent

= AB/AC

= 17/15

Answer:

17/15

Step-by-step explanation:

Secant is the inverse of cosine.

Cosine is the adjacent side divided by the hypotenuse.

cos A = 15/17

sec A = 17/15

use the calculator but the answer is 18.1
