6x - 3y = 12
Answer:
Y = 2x - 4
Slope is 2.
Y-intercept is -4.
Step-by-step explanation:
To find slope in standard form, take -A/B. So 6 is A, -3 is B. -(6/-3) = 2.
And to find the y-int, take C/B. C is 12. So, 12/-3 = -4.
Or you could also rearrange the equation. . .
6x - 3y = 12.Subtract 6 from both sides. -3y = -6x + 12Divide by -3 to isolate the y. y = 2x - 4.heLP PLS I MARK BRAINLIEST ALSO PLEASE INCLUDE STEPS ON IT

Joe stands at the top of a cliff and looks down at a 49-degree angle
of depression at a boulder that is 17 m away from the bottom of the cliff.
How tall is the cliff?
11.2 m
14.8 m
19.6 m
25.9 m
Answer:
Step-by-step explanation:
tan49=h/17
h=17tan49
h=19.6 m
The height of the cliff is 19.6 m tall
A right angled triangle is a triangle (has three sides and three angles) in which one of the angles measure 90°.
Trigonometric ratios is used to show the relationship between the sides of the right angled triangle and its angles.
Let h represent the height of the cliff. Let θ = 90 - 49 = 41°. Hence:
tan(41) = 17/h
h = 17 / tan(41) = 19.6 m
Therefore the cliff is 19.6 m tall

Lula is reading a book for school that is 175 pages long. So far, she has read 50 pages. She can read 25 pages per hour. How many hours will it take her to finish the remainder of the book? Which answer choice best represents the unknown quantity in this problem ?
Answer: 5 hours
Step-by-step explanation:
She has already read 50 pages so we need to deduct that to calculate the answer:
= 175 - 50
= 125 pages left
She can read at a speed of 25 pages per hour. The number of hours it would take to read the remainder of the book would therefore be:
= 125 pages / 25 pages per hour
= 5 hours

Copy the shape and fill in the missing angle. Sow the work. Thanks.
Answer:
The first triangle can be solved using the triangle sum theorem.
There is a vertical angle, so 75 is the angle at the bottom left. 45 is also a vertical angle. Now we have 75+45+x=180, where x is the missing angle. x is 60.
A straight line = 180 degrees, so 60+79+y, where y is unknown, is equal to 180. y is 41. Now use the triangle sum theorem for the triangle to the right. 41+68+z, where z is unknown, = 180. Z is 71.
Now the last part is to find the question mark. A straight line is 180 degrees, so 71+"?" is 180. Simplify to find that "?" is 109.

Find two numbers whose product is 25 and whose sum is -10
A product is an answer to a multiplication problem and sum is the answer to an addition problem.
25 is the product, and -10 is the sum.
Factors of 25 is 5 and 5.
-5+-5=10.
But two negatives multiplied equals a positive.
-5 x -5=25
-5 + -5 = 10

hope it helps
Answer:
The two numbers are -5 and -5
Step-by-step explanation:
Let x and y be the two numbers respectively
xy = 25 --(1)
x + y = -10 --(2)
From (1), x = 25/y [You get x in terms of y]
Sub x = 25/y into (2)
25/y + y = -10 [Equation (2) is x + y = -10, but you got x = 25/y]
[Multiple the whole equation by y]
25 + y^2 = -10y
y^2 + 10y + 25 = 0 [This is a quadratic equation if you don't know]
y = -5
Sub y = -5 into (1)
x = -5

divide 54 by 9, and you get 6. this is because for every 5 sam gets bethan will get 4. if you add, that, you will get the total amount for 1 share. since there are 6 shares, you multiply that by the amount of eros sam and bethan gets each share.

What is the volume of the prisms below?
What equation would you use for the last picture?
Answer:
8) 131.118in^3
9) 18cm^3
Step-by-step explanation:
8) Volume of the prism = Length * Width * height
Volume of the prism = 4.1in * 8.2in * 3.9in
Volume of the prism = 131.118in^3
Hence the volume of soil that will fill the prism is 131.118in^3
9) Volume of the triangular prism = Base Area * Height of prism
Base Area = 1/2bh
Base Area = 1/2 * 4 * 3
Base Area = 6cm^2
Height of the prism = 3cm
Volume of the prism = 6cm^2 * 3cm
Volume of the prism = 18cm^3

What are simple and compound interests?Simple interest is often a predetermined percentage of the principle amount borrowed or lent paid or received over a specific time period.
Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.
The formula for simple interest is SI = (p×r×t)/100 and the formula for compound interest is A = P(1 + r/100)ⁿ.
∴ P + (p×r×t)/100 + P(1 + r/100)ⁿ is the total amount after 2 years.
= 450 + (450×4.5×2)/100 + 350(1 + 4.25/100)².
= 450 + 40.5 + 350(1.0425)².
= 490.5 + 380.38.
= $870.88.

Answer:
a) BD = 5
b) FD = 13
Step-by-step explanation:
For both questions we follow pythagoras therom.
For the first one we do 3^2 +4^2 = 25 and then we root this answer to 5
For the second we have to find the base of GD in order to find FD. GD will be 4^2+12^2 which equals to 160 and then you root.
Finally, we can find FD which is sqaure root of 160^2 + 3^2 = 169. The square root of 169 is 13. Answer is 13.
Answer:
Step-by-step explanation:
AD =BC = FG = EH = 3
AB = DC = EF =HG = 4
BF =AE = DH = CG = 12
Use Pythagorean theorem,
Hypotenuse² = base² +altitude²
BD² = DC² + BC²
= 4² + 3²
= 16 + 9 = 25
BD = √25
BD = 5
DG² = DC² + CG²
= 4² + 12²
= 16 + 144
= 160
FD² = DG² + FG²
= 160 + 3²
= 160 + 9
= 169
FD = √169 = 13
FD = 13
