5x = –25 + 5y 10y = 42 + 2x

1 answer:

3 0

To solve this equation there are many ways you can do to solve. One way is to simply substitute one variable for another.

5x = 5y - 25
X = y - 5

10y = 42 + 2x
10y = 42 + 2(y - 5)
10 y = 42 + 2y - 10
8y = 32
Y = 4.

X = y - 5
X = 4 - 5
X = -1.

P(X,y) = P(-1,4). This would be the solution or the point where they would intersect.

According to the Rational Root Theorem, what are all the potential rational roots of f(x) = 5x3 – 7x + 11?

iogann1982 [59]

ANSWER

$\pm1,\pm11,\pm \frac{1}{5} \pm \frac{11}{5}$

EXPLANATION

The given function is;

$f(x) = 5 {x}^{2} - 7x + 11$

The constant term is 11.

The coefficient of the leading term is 5.

The factors of 11 are ±1,±11

The factors of 5 are ±1,±5

According to the Rational roots Theorem,

the potential roots are obtained by expressing the factors of the constant term over the coefficient of the leading term.

$\pm1,\pm11,\pm \frac{1}{5} \pm \frac{11}{5}$

X and y<br> are supplementary angles. y<br> measures 156<br> What is the measure of a?

Troyanec [42]

Supplementary angles need to add up to 180 degrees.

Subtract Y from 180:

X = 180 - 156 = 24

X = 24 degrees
