Answer:

you know that the coefficient of x is one so to find x the real equation is x+27= -12 so u cross over 27 to the right it will be -12-27=-39.

What is the largest of 3 consecutive integers such that the sum of the first and third is equal to three times the second.

Norma-Jean [14]

Answer:

Step-by-step explanation:

What is the largest of 3 consecutive integers such that the sum of the first and third is equal to three times the second?

3 consecutive angles

= x, x + 1, x + 2

We are told in the question that:

the sum of the first and third is equal to three times the second

a + c = 3b

x + x + 2 = 3(x + 1)

2x + 2 = 3x + 3

3x - 2x = 2 - 3

x = -1

The largest of the three numbers is the third number

= x + 2

x = -1

x + 2 = -1 + 2

The third and largest number is 1

SAT question Can someone explain to me what this is asking

frozen [14]

Answer:

Step-by-step explanation:

The vertex is the turning point of the parabola.

First find the zeros by equating y to zero, that is

(x - 6)(x + 12) = 0

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 12 = 0 ⇒ x = - 12

The vertex lies on the axis of symmetry which is situated at the midpoint of the zeros, thus

$x_{vertex}$ = $\frac{6-12}{2}$ = $\frac{-6}{2}$ = - 3

Thus the x- coordinate of the vertex is x = - 3 → B

Your furniture store sells two types of dining room tables. The first, type A, costs $210 and you make a $21 profit on each one.

zimovet [89]

Answer

In order to minimize total cost sell A type 40 numbers and B type 90 numbers

Solution

furniture store sells two types of dining room tables.

The first, type A, costs $210 and you make a $21 profit on each one.

The second, type B, costs $180 and you make a $20 profit on each one.

We can order no more than 130 tables this month, and you need to make at least $2640 profit on them.

Let x be the number table Type A sold, type B sold = 130-x

To find the value of x

21x +(130-x)20=2640

solving we get x=40

There are two possibilities

A type sold =40 B type sold = 130 - 40 =90

total cost = 40 x 210 + 90 x 180 = 24600

A type sold =90 B type sold = 130 - 90 =40

total cost = (90 x 210) + (40x180)=26100

In order to minimize total cost, choose first possibility

sell A type 40 numbers and B type 90 numbers
