Describe how to plot -3 3/4 on a number line?

On the number line, negative numbers go to the left. Since -3 3/4 is negative, go 3 spaces to the left.

When plotting a fraction or decimal on a number line, you need to estimate. If there are half marks in between the numbers, plot the point near the half mark. If it's -3 3/4, count 3 spaces, then go to the half mark of -3 to -4, and plot the 3/4 in between the -3 and -4 half mark. If there is no half mark, place it near the -4 mark.

The red line represents the half mark, the blue line represents where the point would go. Notice how when negative, the numbers go higher as they go left.

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
