Locate 1 on the x axis. This is the horizontal number line.
Draw a vertical line through 1 on the x axis. Extend this vertical line as far up and down as you can.
Notice how the vertical line crosses the blue curve. Mark this point. Then draw a horizontal line from this point to the y axis. The horizontal line will touch -4 on the y axis. So that means the point (1,-4) is on the curve.
If the input it is x = 1, then the output is y = -4
So that's why the answer is choice A
Answer:
B 20r
Step-by-step explanation:
r² + + 100
r² = (r ) ( ) signs are all positive. 100 = (10) (10) last number. so
(r + 10)(r + 10)
r(r+ 10) + 10(r + 10)
r² + 10r + 10r + 100
r² + 20r + 100
Answer:
(D)
Step-by-step explanation:
The given fractions are:
.
We have to find the product of the given fractions, that is:
=
Simplifying the mixed fractions, we get
=
=
Converting the answer into mixed fraction, we get
=
which is the required answer.
Grams of cocoa =30% of 50g=(30/100) * 50 g=(30 * 50 g)/100=15 g
Soltution: 15 g
