Subtracting a negative means that you will add the number. Convert the symbols to get the following:
y + 10 = 12
Subtract 10 from both sides.
y = 2
Answer:
A
Step-by-step explanation:
f(x)=x^2-4x+3
x coordinate: -b/2a
-(-4)/2(1)=4/2=2
and to find the y coordinate just plug in the value of -b/2a for x and solve for y
Answer:
50
Step-by-step explanation:
so half a dollar is $0.50. We multiply by 9, which gives you $4.50. But the customer gave $5, so they would get $0.50 back.
Answer:
A = 43°
b = 25.8 (3 sig. fig.)
c = 14.5 (3 sig. fig.)
Step-by-step explanation:
Using angle sum of triangle, we get A = 180 - 104 - 33 = 43°
Using sin law,
b/sin104 = 18.1/sin43
b = 25.8 (3 sig. fig.)
c/sin33 = 18.1/sin43
c = 14.5 (3 sig. fig.)
Answer:
Step-by-step explanation:
10+100=1000
20+100=2000
