-4
Because 15x-7x= 8x
8x+5x= 13x
13x= -52
-52 / 13= -4
x = -4
9/10 + 8/100
9/10 + 2×4/25×4
Common denominator is 50.
9/10 + 2/25.
5×9/5×10 + 2×2/2×25
45/50 + 4/50
= 49/50
There are no numbers for this, thus you will have to use the quadratic formula.
Answer:
B
Step-by-step explanation:
The scatter graph shows a decreasing correlation.
Its not A because it's a increasing correlation
its not C because it's neutral
its not D because it's a no correlation graph
Answer:
E: 2.00 + 0.75 [ 2r]
Step-by-step explanation:
r represents the number of miles. For each 1/2 mile the taxi will charge and extra free of $0.75. Then, for each mile, the taxi will charge $0.75*2. For example:
For a trip of 1 mile the taxi will charge:
$2.00+$0.75*2
For a trip of 2 miles, the taxi will charge:
$2.00+0.75*4
For a trip of 10 miles, the taxi will charge:
$2.00+$0.75*20
Notice that the variable fee (the one that depends on the number of miles) is $0.75 times the double of miles. In each case the number of miles is multiplied by two. Then the correct answer is E: 2.00 + 0.75 [ 2r]
