Answer:

Final graph is attached.

Solution is x=2, y=3

Step-by-step explanation:

As we have to solve by graphing to let's graph y=2x-1 first.

we are free to plug any number for x say x=0 and x=2

when x=0 then y=2x-1 changes to

y=2(0)-1=0-1=-1

Hence point is (0,-1)

Similarly

when x=2 then y=2x-1 changes to

y=2(2)-1=4-1=3

Hence point is (2,3).

Now we graph both points (0,-1) and (2,3) then join them by a straight line.


We repeat exactly same process for other line y=-x+5 and get points (0,5) and (2,3)

Now graph both to see the intersection point of both lines

We see that both lines intersect at point (2,3)

<u>Hence final answer is (2,3) or we can also write x=2, y=3.</u>

Solve the inequality –1 &gt; –2(x – 4) – 5(4x – 7).
Ksivusya [100]

Answer:

x > 2

Step-by-step explanation:

–1 > –2(x – 4) – 5(4x – 7)

–1 > –2x  + 8 –20x + 35

–1 >  - 22x + 43

- 1 - 43 >  - 22x

- 44 >  - 22x

\frac{ - 44}{ - 22}   <   \frac{ - 22x}{ - 22}

2 < x

x > 2

OlgaM077 [116]

Answer:

Students collected

  • 85+255=340 pounds of paper;
  • 18+90=108 pounds of cans;
  • 340+108=448 pounds of paper and cans combined in September and October.

Step-by-step explanation:

In September, the students collected 85 pounds of paper and 18 pounds of cans to recycle.

In October, their goal is to collect three times the amount of paper and five times the amount of cans they collected in September.

Hence, in October they collected

  • 85\times 3=255 pounds of paper;
  • 18\times 5=90 pounds of cans.

In total, they collected

  • 85+255=340 pounds of paper;
  • 18+90=108 pounds of cans;
  • 340+108=448 pounds of paper and cans combined in September and October.
