Answer:
12x + 15 = 15
Step-by-step explanation:
step 2
9x + 3x + 15 = 15 ( collect like terms on left side )
step 3
12x + 15 = 15
The plane that would produce a triangle is A, a cut parallel to the vertical axis, directly through the vertical axis.
<h3>What is a squared pyramid?</h3>
A square pyramid is a geometric shape having four triangles, five faces and a square.
<h3>Properties of a squared pyramid</h3>
- It has a five bases
- It has four or greater equilateral triangular faces meeting above the base
- All the edges, sides and angles are equal
Since the sides are equal, cutting parallel to the vertical axis forms a triangle.
Therefore, a cut parallel to the vertical axis, directly through the vertical axis would produce a triangle.

Answer:
see the explanation
Step-by-step explanation:
Let
D -----> Danielle's age
C -----> Counselor's age
we know that
----> equation A
----> equation B
substitute
equation A in equation B
----> equation that can be used to find Danielle's age
Solve for D
<em>Find the value of C</em>
----> equation that can be used to find Counselor's age
substitute the value of D
therefore
Danielle's age is 7 and Counselor's age is 21
The value of m must be 4 and the value of b must NOT be -3.
No matter what numbers they involve, two equations with the SAME slope (m) and a DIFFERENT y-intercept (b) have no solution. This is because they form parallel lines, never crossing and therefore never giving a solution.
