Answer:
A.
Step-by-step explanation:
A penny is worth 1 cents. So, 84 pennies is 84 cents or $0.84
A dime is worth 10 cents, So, 300 dimes is 30 dollars or $30 dollars
$0.84 + $30 = $30.84
84 pennies and 300 dimes is equivalent to 30 dollars and 84 cents.
Hi!to calculate a square root without a calculator is to see if you can get to that whole number by squaring smaller numbers,or multiplying a smaller number by it self.
A and F are true. because A is y=2x+7, and F is y=2x+7.
We know that the equation y=2x+7 has a point 0,7 and with the slope being 2, rise over run would make another point 1,9. And because these are linear equations if the equation y=2x+7 goes through 1,9 then it will go though -2,3 as well.
This is because you can at most, factor out x² and y³
