Answer:
B. y=In x+1
Step-by-step explanation:
because when we substitute x=0 in y =In x+1
we get Y=1
which is matching with the graph
I only know 9) and 10) sorry but here they are:
9) x=16 because ...
3x+20=5x-12
(-3x) (-3x)
20=2x-12
(+12) (+12)
32 = 2x
(32/2) (2x/2)
16=x
10) x=46
angles in quadrilaterals add to 360’
So you do ...
360-134-134-46= 46
This is all I know sorry. Hope you find some more help :)
Answer:
Expression for Perimeter: 6x + 6
x = 12 cm
Verify A = 360:
2(12) x (12+3) = 360
24 x 15 = 360
360 = 360
Step-by-step explanation:
Answer:
X=1,x=3
Step-by-step explanation:
Formula for the quadratic equation
X2-(sum of the two variables)+(product of the two variables)
So back to the question
X2-2x+3=0
X2-3x-x+3=0
X(x-3)-1(x-3)=0
(X-1)(x-3)=0
X-1=0
Make x the subject of formula
X=1
X-3=0
Add 3 to both sides
X=3
Therefore x is 1 or 3
Given is a town has 10,000 two-child families. The town should be divided by smaller units and then conduct a survey on these units to account for the number of two-child families per unit. Combine the number per unit and divide by the total population of the town. Construct a table containing the name of the units and the number of two-child family per unit.
