Using elimination method, what will be the value of y after solving -x - y = 5 and -x + 4y = 15?

natka813 [3]

Answer:

y = 2

Step-by-step explanation:

The variable x can be eliminated by subtracting the first equation from the second.

(-x +4y) -(-x -y) = (15) -(5)

5y = 10 . . . . . . . simplify

y = 2 . . . . . . . . . divide by 5

Assume that 7 is a. We already know that c = 25. The equation is c^2 - a^2 = b^2.
25^2= 625 7^2= 49 625-49= 576
Square root of 576 = 24

1-6. Indicate whether each table or graph represents a proportional

Pie

Answer:

Step-by-step explanation:

Proportional relationship means,

x ∝ y

x = ky

$\frac{x}{y}=k$ where 'k' is the proportionality constant.

From table (1),

$\frac{1}{5}=\frac{2}{9}\neq \text{Constant}$

Therefore, relationship is not proportional.

From table (2),

$\frac{1}{6}=\frac{3}{18}=\text{constant}$

True.

So the relationship will be proportional.

From table (3),

$\frac{\text{hours}}{\text{Miles}}= \frac{2}{110}=\frac{5}{175}=\frac{1}{55}$

Which is constant.

Therefore, relationship will be proportional.

From table (4),

$\frac{\text{Hours}}{\text{Paid}}=\frac{3}{29.25}=\frac{5}{48.75}=0.103$

Which is constant for every term.

Therefore, relationship will be proportional.

The measure of ∠AKG is 133°.

denis23 [38]

Mes ∠AKG = mes ∠AKD + mes ∠ DKG

133° = mes ∠ AKD + 87°

133° - 87° = mes ∠AKD

∠AKD = 46°
