I believe the family budget to make a one- way trip will be $140 because each gallon is $3.50. You need 20 gallons to get there which is $70. You need 20 gallons to get back which is another $70. You add both and is $140. Hope this helped.

The co-ordinates of the point where the line y=x+4 crosses the y-axis

OverLord2011 [107]

Answer:

Therefore the required point where it crosses y-axis is (0 , 4)

Step-by-step explanation:

Given:

$y=x+4$ ...............Equation of line

Intercepts:

The line which intersect on x-axis and y-axis are called intercepts.

There are two intercepts:

x-intercept: The line which intersect at x-axis. So when the line intersect at x-axis Y coordinate is zero.

y-intercept: The line which intersect at y-axis. So when the line intersect at y-axis X coordinate is zero.

For a line crosses Y-axis we have,

$y=x+4$

Put x = 0 in above equation we get

$y=0+4=4\\y=4$

Therefore the required point where it crosses y-axis is (0 , 4)

If the discriminant of a quadratic equation is equal to -8, which statement describes the roots?

agasfer [191]

Answer:

Roots are complex numbers

Step-by-step explanation:

we know that

In a quadratic equation of the form $ax^{2} +bx+c=0$

The discriminant is equal to $b^{2} -4ac$

If $b^{2} -4ac=0$ -----> The equation has only one real root

If $b^{2} -4ac>0$ -----> The equation has two real roots

If $b^{2} -4ac$ -----> The equation has complex roots

In this problem the discriminant is -8

-8 < 0

therefore

Roots are complex numbers
