Graph y= -3/2x-3. could someone please help me. i dont know how to do this :((

You first have to simplify the equation which will get you to y=2x+9
Then you have to graph the equation
Formula:y=mx+b
m = the slope
b = y-intercept
You first start out with the point (0,9) and go up 2 and right 1 or you could do the opposite which would be down 2 and left 1. So some of the points would be (-6,-3) (-5,-1) (-4,1) (-3,3) (-2,5).
And it would form a line
I hope this helped!

Last math question.

Answer:

Step-by-step explanation:

$\text{The slope-intercept form of an equation of a line:}\\\\y=mx+b\\\\m-\text{slope}\\b-\text{y-intercept}\\\\\text{Let}\\\\k:y=m_1x+b_1\\l:y=m_2x+b_2\\\\k\ \perp\ l\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\\\k\ ||\ l\iff m_1=m_2\\=========================$

$\text{We have}\ y=5x+2\to m_1=5\\\\\text{therefore}\ m_2=5.\\\\\text{Put the value of the slope and the coordinates of the given point (-2, 1)}\\\text{to the equation of a line:}\\\\1=5(-2)+b\\1=-10+b\qquad\text{add 10 to both sides}\\1+10=-10+10+b\\11=b\to b=11\\\\\text{Finally:}\\\\y=5x+11$

A friend has a 83% average before the final exam for a course. That score includes everything but the final, which counts for 25

Klio2033 [76]

Answer:

$\mathrm{Best\:course\:grade\:possible:\:}87.25\%,\\\mathrm{Minimum\:score\:on\:final\:to\:earn\:at\:least\:a\:75\%\:for\:the\:course:\:}51\%$

Step-by-step explanation:

Assuming the maximum score for the final is $100\%$ , we can multiply each score by its respective course weight and add them together to give a final score. If your friend did receive this maximum score of $100\%$ , their overall grade for the course would be:

$83(1-0.25)+100(0.25)=\fbox{$87.25\%$}$ .

To find the minimum score they need to earn a 75% for the course, we set up the following equation:

$83(1-0.25)+x(0.25)=75$ , where $x$ is the minimum score she needs.

Solving, we get:

$62.25+x(0.25)=75,\\x(0.25)=12.75,\\x=\fbox{$51\%$}$ .

What is the measure of <6?

wel

Answer: Choice B. 54degrees

Step-by-step explanation:

Angles 1 4 5 8 are equal and angles 2 3 6 7 are also equal. These two sets of angles of supplementary(you‘d get 180 by adding them).

13x+9=180-(5x+9)

by simplifying the equation youll get

18x+18=180

x=9

so angle 7(and therefore angle 6) equals

5*9+9=54

How can I show that 0 is not a natural number

madam [21]

Answer:

The reason why 0 is not a natural number is because does not have a value which is positive or negative. Therefore, since all real numbers are positive integers, we do not assume that zero is a natural number. Although zero is called a number in its entirety.
