Answer:
16 / C
Step-by-step explanation:
-4 x -4 = 16
4 x 4 = 16
two negatives cancel out when multiplying, that is why it equals 16*
Its 400 because 363 is closer to 400 than 300
Answer:
Alex will pay $3,662
Step-by-step explanation:
To find the total cost, we can make an equation modeling y=mx+b, with y being the total cost, m being the monthly charges, x being the amount of time it takes, and b being the 10% down payment.
After plugging in the numbers to the equation, we get y=276(12)+350.
Now all that is left is to solve the equation as follows:
y=3,312+350
y=3,662
Answer:
<h3><u>Part (a)</u></h3>
From inspection of the diagram, the pattern is:
Step 1: 1² + 1
Step 2: 2² + 2
Step 3: 3² + 3
Let x = step number
Let y = total number of squares
Therefore, the equation that represents the relationship is:
y = x² + x
<h3><u>Part (b)</u></h3>
<u />
x² relates to the large square made up of small squares (top part of the image of each step)
x relates to the rectangle of small squares (bottom part of the image of each step)
y is the total number of small squares in the image of each step.
Y=2×2
y=4
4=-3x-1
now add 3x on both sides
3x+4= -1
now substract 4 on both sides
3x = -5
divide 3 on both side
x=-5/3
y= 4
x= -5/3
