I hope this helps you
x=-5 f (-5)=4. (-5)^2 =4.25=100
x=0 f(0)=4.0^2=4.0=0
x=5 f (5)=4.5^2=4.25=100
X=cost for 1 soft taco
x=cost for 1 doubledecker
dory is
11.25=3x+3y
nemo buys
10=4x+2y
we have
11.25=3x+3y and
10=4x+2y
divide second equation by 2
5=2x+y
multiply by -3
-15=-6x-3y
add to first equatin
-15=-6x-3y
11.25=3x+3y+
-3.75=-3x+0y
-3.75=-3x
divide both sides by -3
1.25=x
subsitute
5=2x+y
5=2(1.25)+y
5=2.5+y
minus 2.5
2.5=y
double dekesr cost $2.50
soft tacos cost $1.25
Answer:
I , II, and III are true
Step-by-step explanation:
4+2x≤4
Subtract 4 from each side
4+2x-4≤4-4
2x≤0
Divide by 2
2x/2 ≤0/2
x≤0
0 is less than or equal to 0 so I is true
-4 is less than or equal to 0 so II is true
-3 is less than or equal to 0 so III is true
