Hello!!
Well, the x-intercept is found when y = 0, so plug in y = 0:
-7x + 3(0) = 21
-7x = 21
x = -3
Therefore, the x-intercept of -7x + 3y = 21 is -3.
Hope this helps!! Let me know if you have ANY questions.
So what you have to do is make the denominators equal. You do that by finding out what number they can both go into which is 60. 12 can go into 60 5 times and so you have to do 9/12 times 5 which is 40/60. then 5 goes into 60 12 times so you have to do 1/5 times 5 which is 12/60. Then you see that 40/60 >12/60 therefore the class ate more of the pepperoni pizza
The slope formula is y2-y1/x2-x1 so 5-(-1) =6 Then. 1-(-1)=2 so 6/2. =3. THE ANSWER IS 3
Answer:
x= -11.9
Step-by-step explanation:
-8 - 3.9 = -11.9
-11.9+ 3.9 = -8
Answer:
-233/40
Step-by-step explanation:
5/8 + 1/4 - 2(3/4 + 13/5)
5/8 + 2/8 - 6/4 + 26/5
7/8 - 30/20 + 104/20
7/8 - 134/20
35/40 - 268/40
-233/40
