Find the greatest common factor of 28 and 42.

Mathematics
1 answer:
erastova [34]2 years ago
8 0

Answer: By using EDL(Euclid's Division Lemma), the answer we get is 14

so,

    42 = 28(1) + 14

    28 = 14(2) + 0

therefore, HCF(or greatest common factor) = 14

A student says that the x-intercept of the graph of × + 2y =5 is the point (0,5). Is the student correct or incorrect? Explain y
ivanzaharov [21]

The student is incorrect, the actual x-intercept is (5, 0).

<h3>Is the student correct or incorrect?</h3>

Here we have the equation:

x + 2y = 5

The student says that the x-intercept is the point (0, 5).

So if you look at the point you already can see that the student is incorrect, this is because the x-intercept always must have a y-value of 0. (the graph only intercepts the x-axis when y = 0).

So the point (0, 5) can't be an x-intercept.

For the given function:

x +2y = 5

The x-intercept is given by:

x + 2*0 = 5

x = 5

So it is (5 , 0).
