2) 3x + 4y = 8 2x+y=42 a) (30, -19) b) (31, -20) c) (32,-22) What is the answer

kirza4 [7]

Answer:

Step-by-step explanation:

We can solve simultaneous equations using substitution method, elimination method or graphical method. But for this purpose, we will be using the elimination method.

3x+4y=8 Equation 1

2x+y=42 Equation 2

Multiply Equation 1 by 2 and equation 2 by 3, so as to get the same coefficient for x

2(3x+4y=8)= 6x+8y=16 Equation 3

3(2x+y=42)= 6x+3y=126 Equation 4

Subtract equation 4 from 3, to eliminate x

6x-6x=0

8y-3y= 5y

16-126= -110

We now have 5y=-110

Divide both sides by 5,

y= -110/5

= -22

Substituting for y in equation 2

2x+(-22)= 42

2x= 42+22

2x=64

x= 64/2

= 32

(x, y)

(32, -22)

Pls help I need a good grade

Answer:

Step-by-step explanation:

13). $-\frac{q}{7}\geq -1$

$\frac{q}{7}\leq 1$

$(\frac{q}{7}\times 7)\leq (1\times 7)$

q ≤ 7

14). -12x < 60

12x > -60

$\frac{12x}{12}>\frac{-60}{12}$

x > -5

15). 5 > z - 3

5 + 3 > z - 3 + 3

8 > z

16). 0.5 ≤ $\frac{y}{8}$

0.5 × 8 ≤ $\frac{y}{8}\times 8$

4 ≤ y

Now we can draw these inequalities on a number line.
