Answer:
y = -2x - 2
Step-by-step explanation:
The equation it's asking you to enter is in the form y=mx+b
where m is the slope
and b is the y-intercept
first, find the slope:
find a point on the graph and count how many cells you have to go down and over to get to the next point.
in this case, for each point, you have to go 2 down and 1 right.
The slope must be negative because the line is going across the graph from top-left to bottom-right
because slope is always rise/run, the slope of this line is -2/1, or just -2
Next, find the y-intercept:
look at the line on the graph where x=0
follow it down until you find a point
this is the y-intercept
in this case it is (0, -2)
but in equations we only use the y value of this point
So, the equation is y = -2x - 2
Hope this helps!
Sorry if I over-explained.
I tend to do that a lot.
Its 40 because 4×9 is 39 and that's 90% of 40
Answer:
3 and 4
Step-by-step explanation:
We apply 2 transformations here.
f(x) ----> f(x + a) - this is a shift of a units to the left.
f(x) ---- > f(x) + a - this is a shift of a units vertically up.
x - 1 ----> x + 2 shifts it 3 units to the left.
3 ---->5 shifts it 2 units up.
a) The domain of a function refers to the set of values of x that satisfy the function. On the graph, it is between the minimum value of x on the left and the maximum value of x on the right. Since the line continues to the left and right, it tends towards infinity on both sides. Hence,
Domain = (- infinity, infinity)
b) The range of a function refers to the set of values of y that satisfy the function. On the graph, it is between the minimum value of at the bottom and the maximum value of y at the top. The maximimum value of y is - 1 and the minimum is negative infinity. Hence,
Range = (- infinity, - 1}
c) The x intercept is the value of x when y is zero. It occurs at the point where the line cuts the x axis. Since the line doesn't cut the x axis, there is no x intercept.
d) The y intercept is the value of y when x is zero. It occurs at the point where the line cuts the y axis. It cuts the y axis at x = - 4
Thus, y intercept = - 4
e) the function value, f(- 4) is the value of y at x = - 4. From the graph,
f(- 4) = - 2
the function value, f(0) is the value of y at x = 0. From the graph,
f(0) = - 4
Answer:
t+5+x
Step-by-step explanation:
It says Jenny ran 5 more miles than last week so you find the number from last week then add 5. X is the miles she ran this week
