Answer:
3x + y =0
Step-by-step explanation:
We need to create equation whose solution is (-1,3) . So let another point through which it passes be ( 0,0) .
Since at least two points are required for making a line .Slope :-
=> m = -1-0/3-0
=> m = -1/3
Using point slope form :-
=> ( x - x1) = m( y - y1)
=> ( x - (-1)) = -1/3( y - 3)
=> (x + 1 )3= -y + 3
=> 3x +3 = -y + 3
=> 3x + y = 0
✔️ Checking :-
(-1,3)=> 3(-1) + 3 = 0
=> -3+3=0
=> 0 = 0
• Hence the equation can be 3x + y = 0 .Please help i will give decent points if corrected

Step-by-step explanation:
(3x)^2(2x-3y)
work out the first term
9x^2(2x-3y)
distribute
18x^3-27x^2y
Answer:
(d.) [tex]18x^3-27x^2y[/tex]
Step-by-step explanation:
When given the following equation,
[tex](3x)^2(2x-3y)[/tex]
Systematically perform the operations. Use the order of operations, the order of operations states the following,
1. Parenthesis
2. Exponents/ radicals
3. Multiplication/ Division
4. Addition/ Subtraction
Remember, when performing an exponential operation, one multiplies the base by itself the number of times the exponent indicates. In the given equation, perform the exponent by multiplying the base (3x) by itself twice.
[tex](3x)^2(2x-3y)\\\\(3x)(3x)(2x-3y)\\\\(9x^2)(2x-3y)[/tex]
Now distribute, multiply every term inside the parenthesis by the term outside of it
[tex](9x^2)(2x-3y)\\\\(9x^2)(2x) + (9x^2)(-3y)\\[/tex]
Simplify,
[tex]18x^3-27x^2y[/tex]
Therefore the solution is (d.) [tex]18x^3-27x^2y[/tex]

Find the measure of arc BC
Answer:
100°
Step-by-step explanation:
is 25% of the circle
Answer:
BC = 100°
Step-by-step explanation:
The chord- chord angle BDC is half the sum of the arcs intercepted by the angle and its vertical angle, that is
[tex]\frac{1}{2}[/tex] ( BC + AE) = 85° ( multiply both sides by 2 to clear the fraction )
BC + AE = 170°
BC + 70° = 170° ( subtract 70° from both sides )
BC = 100°

how much will it rain in 27 hours?
Answer:
9.45 inches
Step-by-step explanation:
We should make a proportion for this one.
4.2/12=x/27
Now we cross multiply.
12x=113.4
Now we divide both sides by 12.
x=113.4/12
We solve 113.4/12.
x=9.45 inches

Answer:
X= 5i-2, x=5i-2
Step-by-step explanation:
Step-by-step explanation:
[tex] {x}^{2} - 4x + 29 = 0 \\ x = \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} \\ x = \frac{4± \sqrt{ - 100} }{2} \\ x = \frac{4±10i}{2} \\ x = 2±5i \\ x = 2 + 5i \: \: or \: \: x = 2 - 5i[/tex]
How many different triangles can you make if you are
given these three lengths for sides?
17 cm
13cm
23cm
Answer:
1 triangle can be formed
We are given three side lengths, which are 17cm, 23cm, and 13cm. So, we can form the triangle when;
17 + 23 > 13
17 + 13 > 23
23 + 13 > 17
Since the above conditions are met, then we can form one triangle.
Now, each next triangle with the same sides lengths will be congruent to the first triangle by SSS postulate.
SSS postulate states that: If the three sides of a triangle are congruent to the three sides of another triangle, then the two triangles are congruent.
Thus, only 1 triangle can be formed.

What is the first step to finding the volume of the cylinder?
A.
Find the product of the diameter and the height.
B.
Use the diameter to find the area of the cylinder.
C.
Find the sum of the diameter and the height.
D.
Use the diameter to find the radius of the cylinder.
Answer:
D
Step-by-step explanation:
you find the radius by using the diameter
hence radius = diameter divide by 2 which is 1÷2 which is 0.5
next step the volume of the cylinder is πr^ 2h
22÷7 × 0.5×0.5×8 gives you 6.2857 to 5 significant number
The volume of the cylinder will be 6.28 square yards.
What is a cylinder?A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.
The diameter of a cylinder is 1 yd.
The height is 8 yd.
Then the volume of the cylinder will be
Volume = (π / 4)d² h
Volume = (π / 4) x 1² x 8
Volume = (π / 4) x 8
Volume = 2π
Volume = 6.28 square yards

What is a Pythagorean theorem?Pythagorean theorem states that in the right-angle triangle the hypotenuse square is equal to the sum of the square of the other two sides.
Given that a 20-foot ladder is placed against a building and must just reach a window that is 8 feet of the level ground the latter will be unstable if the base is more than 15 feet from the bottom of the building.
Calculate the base of the triangle by using the Pythagorean theorem:-
H² = P² + B²
B² = H² - P²
B² = 20² - 8²
B = √( 400 - 64 )
B = √336 = 18.33 feet
Therefore, the length of the base is 18.33 feet greater than 15 feet then the ladder will be unstable.

The sum of three numbers is 85. The third number is 7 more than the first. The second number is 2 times the third. What are the numbers?
Answer:
16, 46, 23
Step-by-step explanation:
let the first number be x , then the third number is x + 7 and the second is
2(x + 7) = 2x + 14
Sum the numbers and equate to 85
x + 2x + 14 + x + 7 = 85
4x + 21 = 85 ( subtract 21 from both sides )
4x = 64 ( divide both sides by 4 )
x = 16
x + 7 = 16 + 7 = 23
2(x + 7) = 2(16 + 7) = 2(23) = 46
The numbers are 16, 46, 23

You roll a six-sided die. What is the probability that it is an odd number or less than four? Round your answer to the nearest thousandth.
Answer:
Probability is calculated as # of favorable outcomes / # of possible outcomes.
Our favorable outcomes are 1, 2, 3, 4, 5.
There are 6 total outcomes.
5/6 = 0.833
Answer:
.667
Step-by-step explanation:
There are 3 possibilities for an odd number. 1,3 and 5
For a number less than four, there are also 3 possibilities, 1,2 and 3 (Since it's not four or less)
Counting the uniquue numbers which are not repeated, you have 1,2,3,5 so the odds are 4/6 of rolling an odd or less than four number.
Since it's asking to round, I assume we need to convert to a decimal.
Decimal: .667
Percentage: 66.667%
Both answers are rounded to the thousandth.
