Answer:

A) (4, 8)

General Formulas and Concepts:

Algebra I

Functions
Vertical Line Test - The function must have only one y-value per x-value

Step-by-step explanation:

Step 1: Define

Relation {(4, -5), (-3, -2), (5, -2), (1, 7), (4, 8)}

Step 2: Identify

When we apply the Vertical Line Test, we see that we have an error at x = 4. Therefore, this relation is not yet a function.

We can see that if we remove either (4, -5) or (4, 8), the relation would then pass the Vertical Line Test and become a function.

Therefore, our answer is A) (4, 8)

Solve the system of equations. −5x−3y−9=0 4x−18y−54=0 y=? x=?

Darina [25.2K]

Answer:

Step-by-step explanation:

Eq. 1 ) −5x−3y−9=0

Eq. 2) 4x−18y−54=0

there are two routes to solve this, Substitution or elimination, I'll go for the 2nd one because I can see that the y values are a multiple of each other :)

6 *( −5x−3y−9=0 )

Eq. 3) -30x -18y =54

subtract Eq. 2 from Eq. 3 :)

-30x -18y =54

-( 4x−18y=54)

-34x = 0

so according to the equations then x =0 but, that's not really a full answer, so now we should go back and try the other method, substitution,

then:

-5x = 9 +3y

x = - 9/5 + (-3/5)y

now plug that into Eq. 2

4( - 9/5 + (-3/5)y ) - 18y = 54

-36/5 + (-12/5)y -18y = 54

(-12/5)y - (90/5)y = 54+36/5

-(102/5)*y =270/5+36/5

-(102/5)y = 306/5

y = (-5/102)*(306/5)

y = -306/102

y = -3

then plug in for either equation

-5x-3( -3) = 9

-5x + 9 = 9

-5x = 0

x = 0

now we have the full answer

check it by plugging in both x and y into the 2nd equation

4(0) - 18(-3) = 54

54= 54

this seems good

At the local grocery store, cans of beans are arranged in rows. The number of cans in each row forms an arithmetic sequence. The

Elodia [21]

In an arithmetic series, the value of the nth term is calculated using the equation,
an = ao + (n - 1)(d)
where an and ao are the nth and the 1st term, respectively. d is the common difference, and n is the number of terms.

In the given, an = 48, a0 = 93, d = -5 and n is unknown. Substituting the known values,
48 = 93 + (n - 1)(-5)
The value of n from the equation is 10. Thus, the answer is the last choice.
