Answer:
8xy-3y + 2(9x-5y+4) = 18
Step-by-step explanation:
We need to find the value of the given expression:
8xy-3y + 2(9x-5y+4) ....(1)
when x = 3 and y = -4
Put the values of a and y in equation (1)
8×3×(-4)-3(-4)+ 2(9×3-5(-4)+4)
= -96 +12 + 2(27 + 20 +4)
= -84 + 2(51)
= -84 + 102
= 18
Hence, the value of the given expression is 18.
Answer:
Absolute Value Is Pretty Simple Actually In Middle School Math. Absolute Value Refers To The Numerical Difference From 0 To The Integer. To Find Absolute Value All We Have To Do Is Find The Difference From 0 To The Number. For Example -9 The Absolute Value Is 9 Because On A Numberline There Are 9 Spaces Between 0 and -9 and +6 Is 6.
(This Is How We Learned It In Middle School There Is A Higher Level To This Tho)
X²-11x+19=-5
First collect like terms
x²-11x+19+5=0
x²-11x+24=0
Factor
(x-8)(x-3)=0
Isolate values of x
x-8=0, x=8
x-3=0, x=3
Thus
x=8,3
