First u do 1+3+4 which gives u 8...then divide it from the number 56 which gives u 7..then after do (multiplication) 1*7= £7...then 3*7=£21 and then 4*7=£28....ur answer is £7.00, £21.00 and £28.00.....to check them if it's right u could do 7+21+28 which gives u exactly £56.00...so yap hope this helped u :)
-9y=-3x+216
y=1/3x-24
m=-3
y=-3x+16 is perpendicular to the line
acknolegde requirements:
straight line.(horizontol or vertical? i dunno)
passes through 3,3
perpindicular to y=-x-4
perpidicular lines have negative recipricals
-1 ---- 1
y-3= 1(x-3)
y-3=x-3
cancel out
y=x
Answer:
f(-3) = -8, f(2) = 4
Step-by-step explanation:
-3 fits with in the rule x ≤ 0.
Therefore 3x + 1 is the function for -3, so f(-3) =-3*3 + 1 = -8.
2 fits with in the rule x ≥ 2.
Therefore 4 is the function for x = 2, so f(2) = 4.
