Answer:
y=4/5x-0.8
Step-by-step explanation:
Answer:
90.3
Step-by-step explanation:
.6×.85=.51
.2×1.00=.2
.1×.97=.097
.1×.96=.096
weight in %, times, grade in %
then add them up
.51 + .2 + .097 + .096 = .903
.903=90.3%
Answer: The error is that 9 is a composite number. The correct answer is 27= 3 x 3 x 3
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
Y = -x + 4
y = 3x + 3
3x + 3 = -x + 4
3x + x = 4 - 3
4x = 1
x = 1/4
y = 3x + 3
y = 3(1/4) + 3
y = 3/4 + 3
y = 3/4 + 12/4
y = 15/4
solution is (1/4,15/4)
so line y = -x + 4 intersects the line y = 3x + 3 at (1/4,15/4)
