Well, let's check if your inequality is true. We have to add the 3 scores up and divide them by 3 to know the average.

73 + 81 + 86 = 240
240 / 3 = 80

80%

That's true, now let's check 101.

73 + 81 + 101 = 255
255 / 3 = 85

85%

That's true.

Your inequality is correct.

A polygon is translated 3 units to the right and 4 units down, then it’s reflected across the x-axis, and then it’s dilated by a
Marrrta [24]

Answer:

(x,y)\rightarrow (4x+12,-4y+16)

Step-by-step explanation:

<u>1 transformation</u> - translation 3 units to the right and 4 units down. This translation has the rule

(x,y)\rightarrow (x+3,y-4)

<u>2 transformation</u> - reflection across the x-axis. This reflection has the rule

(x,y)\rightarrow (x,-y)

<u>3 transformation</u> - dilation by a factor of 4 with the origin as the center of dilation. This dilation has the rule

(x,y)\rightarrow (4x,4y)

Now, the sequence of these three transformation has the rule

(x,y)\rightarrow\limits^{\text{1st transformation}} (x+3,y-4)\rightarrow\limits^{\text{2nd transformation}}(x+3,-(y-4))\rightarrow\limits^{\text{3rd transformation}} (4(x+3),4(-(y-4)))\\ \\(x,y)\rightarrow (4x+12,-4y+16)

In March, Isaiah and Freddie had the same amount of money in their savings accounts. In April, Isaiah deposited $210 into his ac
MatroZZZ [7]
Let the amount deposited by each of them in march be m.
in April, Isaiah deposited 210$, this means the amount in his account became m+210
Freddie increased the amount by 15%, this means that the amount of money in his account became: m+0.15m
since both values are still equal, we will equate both equations and solve for m.
m+210 = m+0.15m
0.15m = 210
m = 1400$
