Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

x - 2y = 12

5x + 3y = -44

Step 2: Rewrite Systems

x - 2y = 12

[Multiplication Property of Equality] Multiply everything by -5: -5x + 10y = -60

Step 3: Redefine Systems

-5x + 10y = -60

5x + 3y = -44

Step 4: Solve for y

Elimination

Combine 2 equations: 13y = -104
[Division Property of Equality] Divide 13 on both sides: y = -8

Step 5: Solve for x

Define original equation: x - 2y = 12
Substitute in y: x - 2(-8) = 12
Multiply: x + 16 = 12
[Subtraction Property of Equality] Subtract 16 on both sides: x = -4

Answer:

5.5; 11.00; 16.50

$E = 5.5h$

Step-by-step explanation:

Given

The attached table

Solving (a): Complete the table

First, calculate the slope (m)

$m = \frac{E_2 - E_1}{h_2 - h_1}$

So:

$m = \frac{27.5- 22.00}{5-4}$

$m = \frac{5.50}{1}$

$m = 5.50$

So, the equation of the table is:

$E = m(h - h_1) + E_1$

$E = 5.5(h - 4) + 22$

$E = 5.5h - 22 + 22$

$E = 5.5h$

When h =1,2,3

$E = 5.5 * 1 = 5.5$

$E = 5.5 * 2 = 11.00$

$E = 5.5 * 3 = 16,50$
