A) Annie= J+3

B) J+(J+3)= 18

C)
2J+3= 18
-3 -3
2J= 15
1/2(2J) =(15)1/2
J=7.5
18-7.5= 10.5

Answer:

Step-by-step explanation:

James' age = J

a) Annie is 3 years older than James so,

Annies age = 3 +J

b) Sum of their ages is 18 so,

Annies age + James' age = 18

= 3 + J + J = 18

2J = 18-3

J = 15/2 = 7.5

c) Annies age = 3 + J = 3 + 7.5

= 10.5 years

2: Write out a system of equations that has infinite solutions. Explain why it has infinite
Rasek [7]

Answer:

Below!

Explanation:

A system of equations with infinite solutions defines that both the equations are identical and are overlapping when the lines are graphed. An example could be y = 5x + 9 and y = 5x + 9. These sets of equations have infinite solutions because they are the same and when graphed, they overlap.

Anyone mind helping me!?
Lynna [10]

Answer:

see explanation

Step-by-step explanation:

3x² + 5x + 2 = 0

(a)

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 3 × 2 = 6 and sum = 5

The factors are + 3 and + 2

Use these factors to split the x- term

3x² + 3x + 2x + 2 = 0 ( factor the first/second and third/fourth terms )

3x(x + 1) + 2(x + 1) = 0 ← factor out (x + 1) from each term

(x + 1)(3x + 2) = 0

(b)

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

3x + 2 = 0 ⇒ 3x = - 2 ⇒ x = - \frac{2}{3}
