Hello,
y=5+x
y=x²-7
==>x²-7=5+x
==>x²-x-12=0
==>(x-4)(x+3)=0
The points are:
(4,9) and (-3,2)
19.2 is 24% of 80
Change the percentage to a decimal by dividing over 100:
Multiply 0.24 by 80:
If you are talking about building blocks, then you would get one 10 and 3 ones, then subtract that from 7 ones and would get 6
Answer:
3,312
lets be real who arctually looks at the step by step just use a calculator for this one
RS+ST=RT
RS=7y-4
ST=y+5 using RS and RT in the first equation gives you:
7y-4+y+5=RT combine like terms on left side
8y+1=RT, and we are told that RT=28 so:
8y+1=28 subtract 1 from both sides
8y=27 divide both sides by 8
y=27/8
(RS=19 5/8, ST=8 3/8, RT=28)
