Answer:
D. y = 5x - 11.
Step-by-step explanation:
One equation of a straight line is y = mx + c where m = slope and c = the y-intercept..
Lines which are parallel have the same slope.
So the equation will be y = 5x + c so we have to find c.
As we are given a point on the line we now use the point slope form:
y - y1 = m(x - x1) where (x1, y1) is a point on the line:
The point is (3, 4) so we have:
y - 4 = 5(x - 3)
y - 4 = 5x - 15
y = 5x - 15 + 4
y = 5x - 11.

Answer: 428
Step-by-step explanation:
This is a substitution problems,
Just substitute for the values of x and y , multiply them out and add.
Here we go;
5x³ + 4y³
= 5(4³) + 4(3³)
= 5( 4 x 4 x 4 ) + 4( 3 x 3 x 3)
= 5 x 64 + 4 x 27
= 320 + 108 add directly or find the common factor
= 4(80 + 27)
= 4(107)
= 4 x 107
= 428
