I think it is 42 because 2.75 + 4.25 is 7 x 6= 42
Answer:
c or the 3d one
Step-by-step explanation:
To find the slope of a line given the coordinates of two points, you should use the formula, Slope=y2-y1/x2-x1.
To find the slope of a line which contains the coordinates (8,-3) and (-2,7), you should substitute them into the previous mention formula.
Slope=y2-y1/x2-x1
Slope=(7--3)/(-2-8)
Slope=(10)/(-10)
Slope=-1
The slope of the line which contains the coordinates (8,-3) and (-2,7) is -1 or in other words letter A from the given choices.
The goal in simplifying numbers
is to reduce it that can be best seen in the eye. In here, you are given 5a x 2c x
3d. Note that 5, 2 and 3 are coefficients and a, c and d, are variables. Multiply first
the coefficients 5, 2 and 3 and you get 30. Always remember that in multiplying
numbers, especially variables, the base of the exponent must be equal. However,
you have variables of a, c and, d. You cannot multiply or add them because they
are different. So the answer is 30acd.
