Answer:
Step-by-step explanation:
multiply 7 times 4 then you add that when you
add 4+1=5 then you multiply those two
The slope of the line that contains the points (1 -1) and (-2 8) is -3
Step-by-step explanation:
Slope measures the steepness of a line. It is the ratio of vertical change to horizontal change. If the line increasing, the slope is positive and if the line is decreasing the slope is negative. If the line is horizontal slope is zero and if the line is vertical slope is undefined.
Equation for slope = (y2-y1)/(x2-x1)
here y2= 8
x2=-2
y1=-1
x1=1
Substituting the following,
slope = (8+1)/(-2-1)
=9/-3
=-3
hence the slope is -3
Answer: -2
Step-by-step explanation: The average rate of a function f(x) from x=a to x=b is given as:
Clearly we are asked to find the average rate of change from x=0 to x=2.
i.e. a=0 and b=2
Also, from the graph it could be observed that:
f(0)=1
and f(2)=-3
Hence, the average rate of change is calculated as:
Hence, the average rate of change for this quadratic function for the interval from x = 0 to x = 2 is:
-2
Answer:0
Step-by-step explanation:
You distribute the 4 on 5&x which will then be 20. Your equation is now 20+4x=20 you then subtract the twenty so then it’s 4x=0 divide by 4 on both sides which gives you 0
