The answer to f(-3)= -3^2+1 is 10 !!
Answer:
![y=5/6\approx0.83](https://tex.z-dn.net/?f=y%3D5%2F6%5Capprox0.83)
Step-by-step explanation:
So we have the equation:
![5(2y+1)=4y+10](https://tex.z-dn.net/?f=5%282y%2B1%29%3D4y%2B10)
First, let's distribute the left side of our equation:
![5(2y)+5(1)=4y+10](https://tex.z-dn.net/?f=5%282y%29%2B5%281%29%3D4y%2B10)
Multiply:
![10y+5=4y+10](https://tex.z-dn.net/?f=10y%2B5%3D4y%2B10)
Now, let's isolate the y-variable. Subtract 4y from both sides:
![(10y+5)-4y=(4y+10)-4y](https://tex.z-dn.net/?f=%2810y%2B5%29-4y%3D%284y%2B10%29-4y)
The right side cancels. Subtract on the left. So:
![6y+5=10](https://tex.z-dn.net/?f=6y%2B5%3D10)
Now, subtract 5 from both sides:
![(6y+5)-5=(10)-5](https://tex.z-dn.net/?f=%286y%2B5%29-5%3D%2810%29-5)
The left side cancels. Subtract on the right:
![6y=5](https://tex.z-dn.net/?f=6y%3D5)
Now, divide both sides by 6. So:
![\frac{6y}{6}=\frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B6y%7D%7B6%7D%3D%5Cfrac%7B5%7D%7B6%7D)
The left will cancel. Therefore:
![y=5/6\approx0.83](https://tex.z-dn.net/?f=y%3D5%2F6%5Capprox0.83)
And we're done!
Answer:
-15
Step-by-step explanation:
(17+3)-(5×7)
=20-35
= -15
(Ans)
So 4's facts
we know that 4 times 2=8 and the associative property of multiplication says
a(bc)=(ab)c
so 7(8) (means 7 times 8) means 7((4)(2)) and associative say we can group them and say (7)(4)(2) so (4)((7)(2)) or 4(14) and 4 times 14=56
7 times 8=56
