Which of the following values of x and y are solutions of the
system of inequalities shown below?
x + 3y < 16
x+y > 10
Answer:
B. x = 9, y = 2Step-by-step explanation:
You can just check the values:
A. x = 2, y = 8
x + 3y = 2 + 3×8 = 26 not <16 ⇒ NOT these values
B. x = 9, y = 2
x + 3y = 9 + 3×2 = 15 <16
x + y = 9 + 2 = 11 >10
YES, x = 9, y = 2 are solutions of the system of inequalities
C. x = 1, y = 5
x + 3y = 1 + 3×5 = 16 not <16 ⇒ NOT these values
D. x = 7, y = 2
x + 3y = 7 + 3×2 = 13 <16
x + y = 7 + 2 = 9 not >10 ⇒ NOT these values

How do i find a scale factor?
Answer:
In two similar geometric figures, the scale factor is the ratio of their corresponding sides, dividing the two corresponding lengths of the sides will gives the ratio, for example
What is the scale factor between 4 cm and 10 cm ?
4 and 10 are divisible by 2
Length A : 4 ÷ 2 = 2
Length B : 10 ÷ 2 = 5
so the scale factor from A to B is 2:5

y = -4x + 1
11y = x + 146
Step 2: Solve for x
Substitution
Substitute in y: 11(-4x + 1) = x + 146Distribute 11: -44x + 11 = x + 146[Addition Property of Equality] Add 44x on both sides: 11 = 45x + 146[Subtraction Property of Equality] Subtract 146 on both sides: -135 = 45x[Division Property of Equality] Divide 45 on both sides: -3 = xRewrite/Rearrange: x = -3Step 3: Solve for y
Define original equation: y = -4x + 1Substitute in x: y = -4(-3) + 1Multiply: y = 12 + 1Add: y = 13What is the surface area of the cylinder with height 6 mi and radius 3 mi? Round your answer to the nearest thousandth

always true
sometimes true
never true
Answer: sometimes true
Step-by-step explanation:
Answer:
sometimes true

In general, any quadrilateral with perpendicular diagonals, one of which is a line of symmetry, is a kite. Every rhombus is a kite, and any quadrilateral that is both a kite and parallelogram is a rhombus. EVERY KITE IS NOT A RHOMBUS.
3y=4.8 (I'm so confused it isn't even funny)
Answer:
y = 1.6
Step-by-step explanation:
4.8/3=1.6
3*1.6=4.8
Answer:
[tex]y = 1.6[/tex]
Step-by-step explanation:
[tex]3y = 4.8[/tex]
Use inverse operations to solve this problem. Inverse operations is a method of solving a linear (and in some cases quadratic) equation. This method has one do the same operations to both sides such that it cancels out the operations done to the variable, and hence, it leaves one with the solution.
In this case, all one has to do is divide both sides by the coefficient of the varibale (y).
[tex]3y = 4.8[/tex]
÷[tex]3[/tex]
[tex]y = 1.6[/tex]

3 6 units right and 5 units up
4. 8 units left and 1 unit down
Answer:
3: P'= (6, 5) Q'= (11, 3) R'= (3, 11)
4: P'= (-8, -1) Q'=(-3, -3) R'= (-12, 5)
Step-by-step explanation:
The question is the explanation basically. Just move the points 6 units right and 5 units up for 3, and move the points 8 units left and 1 unit down for 4.
(I hope that the two questions are called 3 and 4, and it isn't "36 units right" or "4.8 units left)
