Answer: a=4/3
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
9 squared plus 40 squared= 41 squared
1. C) $30.00
If you find how much each Pound is worth, which is $2.50 you multiply that by 12 which is $30.00.
2. < because -3.4 is father from 0 on a number line and -2.1 is closest to 0 on the number line so -2.1 is greater than -3.4. | -3.4 < -2.1
3. C) 1/4 because you need to be able to turn the fraction into a decimal and you need to multiply 4 and 1 by 5 and that is 5/20 then you multiply 5 and 20 by 5 and that gives you 25/100 and now you can turn it into a decimal which is 0.25 and 0.27 is greater than 0.25.
4. A) I because if point S is at (-2, 10) it would be in quadrant II so if point T is a reflection of point S than point T is in the I quadrant because the y-axis is the vertical line going up and down. So you put point T across the y-axis which is
at (2, 10) in quadrant I.
To factor quadratic equations of the form ax^2+bx+c=y, you must find two values, j and k, which satisfy two conditions.
jk=ac and j+k=b
The you replace the single linear term bx with jx and kx. Finally then you factor the first pair of terms and the second pair of terms. In this problem...
2k^2-5k-18=0
2k^2+4k-9k-18=0
2k(k+2)-9(k+2)=0
(2k-9)(k+2)=0
so k=-2 and 9/2
k=(-2, 4.5)
