Answer:

No, it is not a function.

Step-by-step explanation:

A function graph are graphs where the lines do not connect. Since the shape is a circle, many lines in the graph are connecting.

Describe and correct the error the student made when writing the equation of the line that passes through (-8,5)

pshichka [43]

Option D (The student should have used as the slope of the perpendicular line.) is correct.

Step-by-step explanation:

We need to identify the error that the student made in finding equation of the line that passes through (-8,5) and is perpendicular to y = 4x + 2

The slope of the required line would me -1/m because both lines are perpendicular.

So, slope of new line will be: -1/4

because the equation of slope-intercept form is: $y=mx+b$ where m is the slope

Now, for finding equation the student used point slope form i.e $y-y_1=m(x-x_1)$

where y_1 and x_1 are the points and m is the slope.

Putting values:

x_1=-8, y_1=5 and m=-1/4

$y-5=-\frac{1}{4}(x-(-8))\\y-5=-\frac{1}{4}(x+8)\\y-5=-\frac{1x}{4}-2\\y=-\frac{1x}{4}-2+5\\y=-\frac{1x}{4}+3$

This is the correct solution.

The student made error by using the wrong slope he used 2 instead of -1/4

in the step $y-5 = 2(x-(-8))$

So, Option D (The student should have used as the slope of the perpendicular line.) is correct.

You mix the letters m,a,t,h,e,m,a,t,i,c,a and l thoroughly without looking you draw one letter probability p(A) . write the prob

erastovalidia [21]

There are 12 total letters, of which 3 are A's.

This means you have a $\dfrac3{12}=\dfrac14=0.25=25\%$ probability of randomly selecting an A.

Hello do any one know this answer

natita [175]

Answer:

A: y = -2x^2

Step-by-step explanation:

The parent function would be y = x^2 since it is a parabola.

Since the function has a vertical stretch by 2, y = 2x^2.

Finally, the function is inverted so the final equation would be y = -2x^2

Help me plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

elena-s [515]

it’s the last one because it’s an open circle so it doesn’t have a line under it and the way the arrow goes has to fit in with the less and greater than sign
