Hello,
Line 1 is passing through (-4,3), (-2,7) has a slope of (3-7)/(-4+2)=2
Line 2 is passing through (2,9), (4,1) has a slope of (9-1)/(2-4)=-4
One other way:
y=9-1/2 x²
y'=-x
gradient 1=-(-2)=2 for point (-2,7)
gradient 2=-(4)=-4 for point(4,1)
Answer:
oof
Step-by-step explanation:
Answer:
10.54 kg
Step-by-step explanation:
Given that :
Half of blueberries is served with breakfast
The remaining 5270g is served with dinner
How many kilograms of blueberries did the science camp start with :
Total grams of blue berries :
(Grams served at breakfast + grams served at dinner)
Let total blueberries = x
x/2 + 5270 = x
(x + 10540) /2 = x
x + 10540 = 2x
10540 = 2x - x
x = 10540 grams
Amount of kilograms science camp started with = (10540) / 1000 = 10.54 kg
