Y=3x+5
y=3x-5
(I remember that paralell lines have same slope and paralell lines with different y intercepts have no solutions so I wuld say no solutions)
I will solve
set them eaqual to each other
3x+5=y=3x-5
3x+5=3x-5
subtract 5 from both sides
3x=3x-10
subtract 3x from both sides
0=-10
false
there is no solution

They will have no solutions. since the slope (3x) of both equations are the same and they have different y-intercepts (-5 and +5) these lines are parallel and will never intersect

Nesterboy [21]

Answer:

x=15

Step-by-step explanation:

(x-6)+8=17 then remove unnecessary parentheses x-6+8=17 then calculate the sum x + 2 = 17 the move constant to the right hand side and change its sign x = 17 - 2 then subtract the numbers x=15 btw you should use photo math that's what I used

The domain of both f(x) = x - 6 and g(x) = x + 6 is all real numbers. What is the domain of h(x) = ?
dolphi86 [110]
The denominator of a fraction cannot be zero.Therefore in h(x) = f(x)/g(x), g(x) cannot equal zero, x + 6 cannot equal zero, x cannot equal -6. The domain of h(x) is ℜ - {-6}.

A triangular pyramid with a height of 9 inches has a volume of 63 cubic inches. If the height of the triangular base is 6 inches
Bond [772]

Option D: 21 in is the base length of the triangular base.

Explanation:

Given that a triangular pyramid with a height of 9 inches has a volume of 63 cubic inches.

The height of the triangular base is 6 inches.

We need to determine the base length of the triangular pyramid.

The base length of the triangular pyramid can be determined using the formula,

Volume =\frac{1}{3} \times Bh

Substituting Volume=63 and Height=9 in the above formula, we get,

63 =\frac{1}{3} \times B(9)

Simplifying the terms, we get,

63 =3B

Dividing both sides by 3, we have,

21=B

Thus, the base length of the triangular pyramid is 21 in

Hence, Option D is the correct answer.
