Graph the line with the equation y=-2/5x+1
Answer:
Step-by-step explanation:
slope = -2/5
y intercept = (0,1)
The graph of the line y=-2/5x+1 is given below.
To graph the line with the equation y = -2/5x + 1, we can use the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept.
In this case, the slope is -2/5, which means that for every increase of 1 unit in the x-coordinate, the y-coordinate decreases by 2/5 units. The negative sign indicates that the line slopes downward from left to right.
The y-intercept is 1, which is the point where the line crosses the y-axis.
To plot the line, start by marking the y-intercept at (0, 1) on the coordinate plane. From there, use the slope to find additional points. For example, if you move 5 units to the right (because the denominator of the slope is 5) from the y-intercept, the y-coordinate will decrease by 2 units, giving you the point (5, -1).

Answer:
measure of angle ABC is 6 degree.
Step-by-step explanation:
After you found x, you'll plug it in the equation of the angle it's asking for.
Measure of angle ABD, and you know measure of angle ABC = 4x-1.
4(1)-1 = 4-1 = 3
Measure of angle CBD = 2x+1.
2(1) +1 = 3
Measure of angle ABC is ABD + CBD
3 + 3 = 6
Answer:
6°
Step-by-step explanation:
We know that is 4x - 1 + 2x + 1
So it equals
6x
or 6 ( 1) = 6°

Which graph is the graph of f(x)= x-1/x+2
Answer:
Step-by-step explanation:
Right bottom answer
The graph that represents the function f(x) = x - 1/x + 2 is graph (d)
How to determine the graph of the equation?The equation of the function is given s:
f(x) = x - 1/x + 2
The above function is a rational function, and it has its asymptotes at y = 2 and x = -2
From the list of given options, the graph d (bottom right) has its asymptotes at y = 2 and x = -2
Hence, the graph that represents the function f(x) = x - 1/x + 2 is graph (d)
