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:
The square root of x will be evaluated first before the addition of 5. Hence (-3)^2 = 9 and 9 +5 = 14, as per your teacher's answer, which is correct. The answer would not be -4.
Answer:
1/8
Step-by-step explanation:
Kylie's little brother ate 1/4 of 1/2 of the cake. This means he ate 1/8 of the whole cake, since 1/2 is 0.5 of the whole cake, and that means that to find the fraction of what her brother ate, you must divide 1/4 in half, which is 1/8.
