Answer:
Infinite solutions.
Step-by-step explanation:
Let's solve your system by substitution.
3y=9x+15;3x−y=−5
Rewrite equations:
3x−y=−5;3y=9x+15
Step: Solve 3x−y=−5 for y:
3x−y=−5
3x−y+−3x=−5+−3x(Add -3x to both sides)
−y=−3x−5
−y −1 −1=−3x−5
(Divide both sides by -1)
y=3x+5
Step: Substitute 3x+5 for y in 3y=9x+15:
3y=9x+15
3(3x+5)=9x+15
9x+15=9x+15(Simplify both sides of the equation)
9x+15+−9x=9x+15+−9x(Add -9x to both sides)
15=15
15+−15=15+−15(Add -15 to both sides)
0=0
Hello lucker
V= 4/3 π R^3
17 x 17 x 17 = 4913 x 4 = 19652 / 3 = 6550.66667
or 6550.7
6550.7 x 3.14 = <span>20569.198
V = 20569.2</span>
Answer: I don't know the exact details but Egypt is home to some of the world's most famous tombs, among them the monumental pyramids. Egyptians built rectangular benches over graves during the fourth dynasty, which was known as the Masabas period. During this time period, pyramids were constructed by stacking square or rectangular tombs on top of one another.
Step-by-step explanation:
<span>2(x+4)=-5x+1
Use distributive property(Multiply 2 by x and 4).
2x + 8= -5x+1
Add 5x to both sides so that the variable x is only on one side
7x + 8=1
Subtract 8 from both sides
7x= -7
Divide 7 on both sides so that the only thing remaining on the left side is the variable x.
Final Answer: x= -1</span>
Answer: B
Step-by-step explanation:
6 less means you have to subtract. 7 times means you have to multiply by x. This means that your answer should be 7x-6. I hope this helps :)
