Answer:
-8
Step-by-step explanation:
It would be -2+2(-3)
Which means -2 plus 2 times -3
According to PEMDAS you have to do parenthesis first so 2 times -3 is -6 +-2=-8
So the answer is -8
Convert to slope-intercept form, y = mx + b.
Subtract 2x to both sides:
Divide 3 to both sides:
Now it's in slope intercept form, y = mx + b where 'm' is the slope. So the slope here is -2/3, which is Negative.
This is already in slope intercept form. So the slope here is 3, which is Positive.
For #3 and #4, take any two points from the table and plug them into the slope formula.
Let's take (0, 7) and (1, 5).
x1 y1 x2 y2
Subtract:
Divide:
So the slope is negative.
For #4, let's take (2, -8) and (3, -7)
x1 y1 x2 y2
Subtract:
Divide:
So the slope is positive.
Answer:
$34.04
Step-by-step explanation:
The dimensions of a slab is 11 feet by 11 feet by 2 inches or 3.67 yards, 3.67 yards and 0.055 yards
We need to find the cost to pour a slab.
We know that the volume of a cuboid shape is given by :
V = lbh
Put all the values,
V = 3.67 × 3.67 × 0.055
V = 0.74 yards³
Cost,
C = $46 × 0.74
C = $34.04
Hence, the required cost is equal to $34.04.
To calculate this answer you have to sum up the amount of women and amount of men at the concert: 1493 + 1438 = 2931.
Now you have the total amount of people. To get the precentage of the audience that are men, you do this: 1493/2931. (you divide the amount of men with the amount of every person present).
1493/2931 = 0.5093
you multiply 0.5093 by 100
and you get 50.93%. And that is the final answer.
