3x-2y=7 9x-6y=k
No solution

<h3>Answer: Choice C</h3>

No solutions if k is anything but 21

=======================================================

Explanation:

Let's multiply everything in the first equation by 3

3x-2y = 7

3*(3x-2y) = 3*7

9x - 6y = 21

We have the 9x-6y match perfectly with the left hand side of the second original equation.

If k = 21, then we have two identical equations that produce infinitely many solutions.

If k \ne 21, then this system is inconsistent and has no solutions.

Identify an equation in point slope form for the line perpendicular to
Vaselesa [24]
Point slope form is y2-y1=m(x2-x1).

The slope m that is perpendicular to y=-4x-1 will be 1/4 (the opposite reciprocal). Then you can use (-2,7) as the x and y values to plug into the formula:

y-7=1/4(x+2) is the answer.

Can someone please help me I’ll give brilliant thingy

Answer:

Yes, the shapes are similar. Note, the angles are equivalent and the sides are scales of each other satisfying the requirements for similarly.

Step-by-step explanation:

For a shape to be similar there are two conditions that must be met. (1) Must have equivalent angles (2) Sides must be related by a scalar.

In the two triangles presented, the first condition is met since each triangle has three angles, 90-53-37.

To test if the sides are scalar, each side must be related to a corresponding side of the other triangle with the same scalar.

9/6 = 3/2

12/8 = 3/2

15/10 = 3/2

Alternatively:

6/9 = 2/3

8/12 = 2/3

10/15 = 2/3

Since the relationship of the sides is the scalar 3/2 (Alternatively 2/3), then we can say the triangles meet the second condition.

Given that both conditions are satisfied, then we can say these triangles are similar.

Note, this is a "special case" right triangle commonly referred to as a 3-4-5 right triangle.

Cheers.
