Answer:
−7b−9k+6
Step-by-step explanation:
−4b+(−3b)=−7b
+(−9k)=−9k
12−6=6
Y = -0.4x
1) It is a straight line
2) I passes through the origin (0,0), because the y-intercpet is 0.
3) The slope is negative, so it passes throuh II and III quadrants
4) The magnitude of the slope = 0.4
4) The angle of the line with the negative side of the x-axis is that whose tan is 0.4 => angle = 21.8 °
With all that information you can identify the graph, given that you didn't include the options.
To find the slope of a line, we need to use the formula for finding slope, m, which is:
m = change in y/change in x = y2-y1/x2-x1
This means that we must use the given ordered pairs and substitute these values into the formula above. However, it is important to remember that x1 and y1 should be from the same pair and x2 and y2 should be from the other pair, otherwise you will get the wrong answer.
Let's let (x1, y1) be (7,3) and (-5,9) be (x2, y2).
Now, we must plug into the formula.
m = (9-3)/(-5-7) = 6/(-12) = -1/2
Therefore, the slope between these two points is -1/2.
Hope this helps!
We are given cylinder
radius =r=3cm
height=h=8cm
now, we can find surface area
now, we can plug values
now, we need to find dimensions of rectangular with same area
we know that
Area of rectangle =length*width
And each option has one of dimension as 8
so, we can write it as
so,
length =8cm
width
so, option-C..............Answer
