Answer:
x=-5/2, -3
Step-by-step explanation:
2x^2+11x+15=0
factor out the trinomial
(2x+5)(x+3)=0
zero property,
2x+5=0, x+3=0
2x=0-5=-5, x=-5/2
x=0-3=-3
Answer:
5,4
Step-by-step explanation:
here is the rule (4,-5) rotate 90 clockwise = (5,4)
4,-5 will put you in the 4 quadrant rotate it 90 clock wise Put you in the first quadrant
It's 1 mile. She ran an 8th if an mile. If the ran 1/8 of a mile 8 times, it adds up to 1 mile.
Answer:
A.
Step-by-step explanation:
C=2 times j
c=2j
o=j-6
c+j+o=58
subsitte j-6 for o and 2j for c
2j+j+j-6=58
4j-6=58
add 6 to both sides
4j=64
divide both sides by 4
j=16
sub back
c=2j
c=2(16)
c=32
o=j-6
o=16-6
o=10
curtis=32
olivia=10
jonathan=16
equations are
c+j+o=58
c=2j
o=j-6
