(-2, 1), (-4, 2) and (1, -1) are solutions to given inequality y-4x (greater than or equal to) -5

<u>Solution:</u>

Given, inequality is y – 4x ≥ - 5

We have to find the correct answers from given options

<em><u>We have to check option by option. </u></em>

Now, (-2, 1) ⇒ 1 – 4(-2) ≥ - 5 ⇒ 1 + 8 ≥ -5 ⇒ 9 ≥ -5 ⇒ correct answer.

Now, (-4, 2) ⇒ 2 – 4(-4) ≥ -5 ⇒ 2 + 16 ≥ - 5 ⇒ 18 ≥ - 5 ⇒ correct answer

Now, (1, -1) ⇒ -1 – 4(1) ≥ - 5 ⇒ -1 – 4 ≥ - 5 ⇒ -5 ≥ -5 ⇒ correct answer

Now, (4, 0) ⇒ 0 – 4(4) ≥ - 5 ⇒ -16 ≥ -5 ⇒ wrong answer

Now, (5, -2) ⇒ -2 – 4(5) ≥ - 5 ⇒ -2 – 20 ≥ -5 ⇒ -22 ≥ -5 ⇒ wrong answer

Hence, (-2, 1), (-4, 2) and (1, -1) are solutions to given inequality.

Samir buys x cans of soda at 30 cents each and (x+4) cans of soda at 35 cents each. The total cost was $3.35. Find x
NISA [10]
0.30<em>x </em>is the cost of the first type of soda. 0.35(<em>x</em>+4) is the cost of the second type of soda. Put these into an equation looking like:

Cost of Soda A + Cost of Soda B = Total Cost
0.30<em>x </em>+ 0.35(<em>x</em>+4)=3.35 --> Expand 0.35(<em>x</em>+4)
0.30x + 0.35x + 1.4 = 3.35 --> Add the <em>x</em>'s and subtract 1.4
0.65x = 1.95 --> Divide by 0.65
x = 3

Samir buys 3 cans of soda at 30 cents each and 7 (3+4) cans of soda at 35 cents each. Samir buys a total of 10 cans of soda.

Can anyone help me find the surface area of this shape?
Alex Ar [27]
To find the surface area of a cuboid you have to find the areas of all the faces and then add them all up together.
2*2=4
4+4=8 (adding this because there's 2 of these same faces)
9*2=18
18*4=72 (because there's 4 of these same faces)

8+72=80

So the answer is 80cm
