Supplementary Angles: Angles that add up to 180°

Step-by-step explanation:

Step 1: Define

We can see from the diagram that the 2 angles are supplementary

(6x - 10)° + (7x + 8)° = 180°

Step 2: Solve for x

Combine like terms: 13x - 2 = 180
[Addition Property of Equality] Add 2 on both sides: 13x = 182
[Division Property of Equality] Divide 13 on both sides: x = 14

Determine whether the pair of equations represent parallel lines, perpendicular lines, or neither.

Ivahew [28]

Answer:

Parallel

Step-by-step explanation:

Parallel lines have the same slope but different y-intercepts. If you multiply the top equation by 2, you get:

2(12x + 4y = 16)

24x + 8y = 32

This shows that both lines have the same slope, but then you find the y-intercepts, they are different:

1st equation y-int = 4

2nd equation y-int = 9/2 or 4.5

Solve the equation using square roots.

Virty [35]

Answer: LAST OPTION.

Step-by-step explanation:

1. You have the following equation:

$6x^{2}=54$

2. Then you must solve for x, as following:

$x^{2}=54/6\\x^{2}=9\\x=\sqrt{9}\\x=+/-3$

Therefore, as you can see above, the answer for the exercise is the last option.

If f(x)=4x^2+1 and g(x)=x^2-5 find(f+g)(x)

Zepler [3.9K]

Answer:

$\large\boxed{(f+g)(x)=5x^2+6}$

Step-by-step explanation:

$(f+g)(x)=f(x)+g(x)\\\\f(x)=4x^2+1,\ g(x)=x^2-5\\\\\text{Substitute:}\\\\(f+g)(x)=(4x^2+1)+(x^2-5)\\\\=4x^2+1+x^2-5\qquad\text{combine like terms}\\\\=(4x^2+x^2)+(1+5)\\\\=5x^2+6$
