Solve 5x-3y =1, 3x-y=5.

Mathematics
1 answer:
Ghella [55]3 years ago
3 0

Answer:

Below in bold.

Step-by-step explanation:

5x - 3y = 1

3x- y = 5                    Multiply this equation by -3:

-9x + 3y = -15            Now add this equation to the first equation:

-4x = -14

x = -14/-4 = 3.5.

Now substitute for x in equation 1:

5(3.5) - 3y = 1

-3y = 1 - 17.5

-3y = -16.5

y = 5.5.

Determine the exact x-intercepts of y = (x + 4) - 7.
Maslowich

The x-intercept of a graph is the point where the graph crosses the x-axis

<h3>(a) Graph</h3>

The function is given as:

y = (x + 4)^2 - 7

See attachment for the graph of the function.

From the attachment, the approximated x-intercepts are -7 and -1

<h3>(b) Type of solution</h3>

From the attached graph, we can see that the curve crosses the x-axis at non-terminating decimals

Hence, the solutions of the equation are irrational.

<h3>(c) The vertex</h3>

This is the minimum or the maximum point of a parabola.

From the attached graph, the minimum point is at (-4,-7)

Hence, the coordinates of the vertex of the parabola is (-4,-7), and it is exact (not approximated)

(-14) - (-8) = -6

2. Solve the answer choices

(-14) + 8= -6

14 - (-8)= 22

14 + (-8)= 6
