y=-3x + 4
y = 3x - 2
What solution does this system have? How do you
know? Justify(explain).
Answers
Set them equal to each other
-3x + 4 = 3x - 2
Solve the equation
4 = 6x - 2
6x = 6, x = 1
Plug in 1 for any equation to find y
Y = -3(1) + 4
Y = -3 + 4, y = 1
Solution: x = 1, y = 1

A cylinder has a height of 16 meters and a diameter of 26 meters. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
Answers
Answer:
V= 5224.96
Step-by-step explanation:
To find the volume for a cylinder, you need to use the formula
V=(pi)r^2h.
The question gives is the diameter. The radius is half of the diameter, so you would divide by 2.
16/2 = 8.
Now we plug in the numbers and solve.
V= (pi) 8^2(26)
V= (pi)(64)(26)
V=(pi)(1664)
V= 5224.96

What is the area of kite ABCD?
sq yd
Answers
Answer:
51.5?
Step-by-step explanation:
I think it's just length times width divided by 2
The area of the kite ABCD is 51.56 square yards.
What is the area of the kite?A kite's area is the amount of space enclosed or surrounded by a kite in a two-dimensional plane.
A kite's area equals half the product of its diagonal lengths. The formula for calculating a kite's area is:
Area = 1/2 × d₁ × d₂
Where d₁ and d₂ are long and short diagonals of a kite.
Here, AC = 12.5 yards and BD = 8.25 yards
Substitute the values of d₁ = 12.5 yards and d₂ in the formula of the kite's area:
The area of the kite = 1/2 × 12.5 × 8.25
The area of the kite = 51.5625
The area of the kite ≈ 51.56 square yards
Thus, the area of the kite ABCD is 51.56 square yards.

A bag contains white, blue and red ping-pong balls in the ratio 8 : 3 : 2. There are 10 balls. If 10 white and 10 blue balls are removed from the bag, the new ratio is ?
Answers
Answer:
the new ratio of white, red and blue balls is 6:2:1
Step-by-step explanation:
The computation of the new ratio is shown below:
If you have 10 red balls, so the blue balls is in proportion of 3:2 that means 15 would be the blue balls. In addition to this, the while balls is in proportion 8:2 = 4:1 so there is a 40 white balls
Now if 10 white and 10 blue balls would be eliminated
So there is 30 white, 10 red, 5 blue bals
Also
30 = 5 × 6
And,
10 = 5 × 2
so the new ratio of white, red and blue balls is 6:2:1

A triangular prism has a base that is an isosceles triangle with sides 14 cm, 14cm , base 9 cm , and height 13 cm. The height of the prism is 32 cm. What is the surface area of this prism?
Answers
Answer:
Surface area of prism = 1301 cm²
Step-by-step explanation:
A triangular pyramid has 3 rectangular sides and 2 triangular sides.
Now, we are told that the triangular side is isosceles.
This means that two of the rectangular sides which share a side with the equal side of the triangle are equal as well as the 2 triangular sides.
Surface area of prism = 2(area of triangular face) + 2(area of rectangle sharing one side with the equal side of the triangle) + (area of rectangle sharing side with the unequal side of the triangle).
Area of triangle = ½ × base × height
Area of triangle = ½ × 9 × 13 = 58.5 cm²
Since height of prism is 32 cm, then;
area of rectangle sharing one side with the equal side of the triangle = 32 × 14 = 448 cm²
area of rectangle sharing side with the unequal side of the triangle = 32 × 9 = 288 cm²
Thus;
Surface area of prism = 2(58.5) + 2(448) + 288
Surface area of prism = 1301 cm²

How to divide 49 yd in the ratio 1:6?
Answers
Answer:
7:42
Step-by-step explanation:
First off you add the ratio together-
6+1=7
Then you divide-
49÷7= 7
7 is equal to 1 in this ratio.
To write out the ratio you need to multiplicate-
7×1=7
and
6×7= 42
Leaving the as-
7:42
Answer:
7:42
Step-by-step explanation:
First, add up the two numbers in the ratio to get 49.
Next, divide the total amount by 49, i.e. divide £16 by 8 to get £5. £5 is the amount of each 'unit' in the ratio.
Then you need to divide the total amount using that number i.e. 49/16 = 7/42.
To work out how much each person gets, you then multiply their share by the ratios. Therefore, the answer is 7 yd and 42 yds.

A polynomial of degree 3 is multiplied by a polynomial of degree 5. What is the degree of the product?
Answers
Answer:
8
Step-by-step explanation:
The degree of a polynomial refers to the term with the highest exponent. Thus the highest exponent in a degree 3 polynomial is x3; for a degree 5 polynomial, it's x5. When you multiply
x3*x5 = x3+5 = x8.
So the product of a degree 3 polynomial and a degree 5 polynomial is a degree 8 polynomial.
Your leading term will result from the 3-degree term of the first polynomial, and the 5-degree term of the second. So you'll have something like ax3 * bx5. That will result in x3*x5=x8, so your product will have degree 8.
