Determine if (3, 7) is a Solution or not Solution to the linear system.
spayn [35]

Answer:

y = 2x + 1 --> linear

y = -4x + 7 --> non-linear

Not a solution for linear system.

Step-by-step explanation:

for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:

7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.

for (b), we have to substitute our values again. You get:

7 = -4x3 + 7, which is

7 = -12+7, which is not true. So, (b) is not linear.

This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.

This equation represents an exponential function that passes through the point (2, 80).
miss Akunina [59]

we know that

If the point belongs to the graph, then the point must satisfy the equation

we will proceed to verify each case

<u>case A.)</u> f(x)=4(x^{5})

The point is (2,80)

Verify if the point satisfy the equation

For x=2 find the value of y in the equation and compare with the y-coordinate of the point

f(2)=4(2^{5})

f(2)=128

128\neq 80

therefore

the equation f(x)=4(x^{5}) not passes through the point (2,80)

<u>case B.)</u> f(x)=5(x^{4})

The point is (2,80)

Verify if the point satisfy the equation

For x=2 find the value of y in the equation and compare with the y-coordinate of the point

f(2)=5(2^{4})

f(2)=80

80=80

therefore

the equation f(x)=5(x^{4}) passes through the point (2,80)

<u>case C.)</u> f(x)=4(5^{x})

The point is (2,80)

Verify if the point satisfy the equation

For x=2 find the value of y in the equation and compare with the y-coordinate of the point

f(2)=4(5^{2})

f(2)=100

100\neq 80

therefore

the equation f(x)=4(5^{x}) not passes through the point (2,80)

<u>case D.)</u> f(x)=5(4^{x})

The point is (2,80)

Verify if the point satisfy the equation

For x=2 find the value of y in the equation and compare with the y-coordinate of the point

f(2)=5(4^{2})

f(2)=80

80=80

therefore

the equation f(x)=5(4^{x})  passes through the point (2,80)

therefore

<u>the answer is</u>

f(x)=5(x^{4})

f(x)=5(4^{x})
