Answer:
Step-by-step explanation:
hello :
y= x² + x + 1 ....(*)
and
y= -x - 2....(**)
(**)-(*) : 0 = (x²+x+1) -(-x-2)
x²+2x+3 = 0
(x²+2x+1)+2 = 0
(x+1)² = -2 ...... no solutions in R
Answer:
136°
Step-by-step explanation:
QRT and QRO are supplementary angles, so
180 - 44 = 136 degrees
Answer:
$398 and $796
Step-by-step explanation:
w = cost of the washer
d = cost of the dryer
w + d = $1194
w = 2d
Substitute the w into the first equation.
2d + d = $1194
3d = $1194
d = $398
Substitute d into either equation.
w=2(398)
w=$796
5x8=40 so now we take 16 and subtract 40 we get -24
Answer:
you will need to specify a scale and draw the line from which I will solve with simultaneous linear equations
