Answer:
Step-by-step explanation:
Let w be the width
Length = 3w +15
Perimeter = 94 cm
2*(length + width) = 94
2*(3w+15 + w) = 94
2*( 4w + 15) = 94
4w + 15 = 94/2
4w +15 = 47
4w = 47 -15
4w = 32
w = 32/4
w = 8 cm
Length = 3w +15 = 3*8 + 15 = 24 +15 = 39
Length = 39cm
Area = length * width = 39*8 = 312
Area = 312 cm²
Part A: No. The line would have to be straight in order for the graph to be linear.
Part B:
Linear: y=2x-4.
Nonlinear: y=x^2-6.
Answer:
19/35
Step-by-step explanation:
1/7 + 2/5
you need to make both of the denominators equal. to make them equal, multiple 1/7 by 5 to make 5/35 and multiple 2/5 by 7 to make 14/35.
then add the numerators
5/35 + 14/35 = 19/35
Answer: y = 101
Step-by-step explanation:
y - 12 = 89
+12 +12
y = 101
Step-by-step explanation:
y > 6x + 5
y < -6x + 7
