The formula excerpt is an excel syntax which sums the value the values in cell A1 and 2. Hence, the output displayed in A4 will be 12
Excel begin with the equal to sign (=). The expression adds the value in A1 and 2.
Since, the value in A1 = 10
What the expression does is ; 10 + 2 = 12.
Therefore, the output displayed in cell A4 is 12.
Answer:
y = -1x + 2
Step-by-step explanation:
y = -1x + b
5 = -1(-3) + b
5 = 3 + b
2 = b
y = -1x + 2
Answer:
y = -2x + 16.
Step-by-step explanation:
We are given the slope and a point on the line, so
we use the point-slope form of a straight line:
y - y1 = m(x - x1)
Here gradient m = -2, x1 = 4 and y1 = 8 , so we have:
y - 8 = -2(x - 4)
y - 8 = -2x + 8
y = -2x + 16.
Answer:
Step-by-step explanation:
The best way to do this is to let a graphing program do it. You could do it from a chart, but a graphing program can be useful for that as well. We'll make up a mini chart here
x method y
-3 (-3)^2 + 2(-3) + 3 = 6
-2 (-2)^2 + 2(-2) + 3 = 3
-1 (-1)^2 + 2(-1) + 3 = 2
0 3
1 (1)^2 + 2(1) + 3 6
2 (2^2) + 2(2) + 3 11
3 (3)^2 +2(3) + 3 18
See the graph below.
You can pick it out from the graphs you were given.
