Dilate D(7,4) by a scale factor of k = 3
Answer: (21,12)
Step-by-step explanation:
(x - 12y = -4
( x - 9y = 7
9514 1404 393
Answer:
(x, y) = (40, 11/3)
Step-by-step explanation:
The variable x can be eliminated by subtracting the first equation from the second.
(x -9y) -(x -12y) = (7) -(-4)
3y = 11 . . . . . . .simpify
y = 11/3 . . . . . .divide by 3
x -9(11/3) = 7 . . . . substitute for y in the second equation
x = 40 . . . . . . . add 33
The solution is (x, y) = (40, 11/3).
y= 2 over 3 x + 20 when x= 21
Answer:
y=1262 /63 or y=20 and 2/63
Step-by-step explanation:
plug 21 into the equation to get y=2/3(21)+20

Six equal blocks have a total mass of b kg. What is the mass of each block?.
find the y-coordinate of the y-intercept of the polynomial function defined below f(x)=2x(x^2+3)
Answer:
y-intercept is (0,0). Mark brainliest?
Answer:
Step-by-step explanation:
2x([tex]x^{2}[/tex] + 3)
when x = 0 then we have a y intercept
2[tex]x^{3}[/tex] +6x
so b/c both terms have an x in them
we know the only time this function hits the y intercept is when y is zero
got it?
answer y = 0
Write a quadratic equation ax²+ bx + C = 0, whose coefficients are a =-9, b = 0, c = -2
Please I really need your help for this
Let's write -9 where we see A:
-9x² + bx + c = 0Let's write 0 where we see B:
-9x² + 0.x + c = 0(Since B = 0, when it is multiplied by x, it becomes 0 again)
-9x² + c = 0Let's write -2 where we see C:
-9x² + -2 = 0Now we can move on to solving our equation:)
Let's put the known and the unknown on different sides:
(-2 goes to the opposite side positively)
-9x² = 2(it goes as a division because it is in the case of multiplying -9 across)
x² = 2/-9
I could not find the rest of it, but I did not want to delete it for trying very hard. Sorry. It felt like we should take the square root, but I couldn't find it, maybe this can help you a little bit.

Greetings from Turkey:)#XBadeXThe quadratic equation ax²+ bx + C = 0, whose coefficients are a = -9, b = 0, c = -2 will be -9x² + -2 = 0
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that,coefficients fore the equation,ax²+ bx + C = 0, is a =-9, b = 0, c = -2
We have to write a quadratic equation as,
Any equation of the form ax²+bx+c=0 where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
ax² + bx + c = 0
-9x² + 0x + (-2) = 0
-9x² + -2 = 0
-9x² + -2 = 0
Thus, the quadratic equation ax²+ bx + C = 0, whose coefficients are a =-9, b = 0, c = -2 will be -9x² + -2 = 0

Answer:
Step-by-step explanation:
1. f(x) = 5x² + 3x - 1
a. f(0) = 5·0² + 3·0 - 1 = -1
b. f(-1) = 5(-1)² + 3(-1) - 1 = 1
Do the same for f(2), f(√2), f(a+2), and f(a).
Then do the same thing for the next function.
2. f(x) = x/(1-x)
a. f(0) = 0/(1-0) = 0
Do the same for f(-1), f(2), f(√2), f(a+2), and f(a).

Disney The Jungle Book (the first one): Mowgli (played by Neel Sethi) is a young boy that was raised by a family of wolves. One day he has to leave his home when the fearsome tiger, named Shere Khan (voiced by Idris Elba) unleashes a powerful roar. With aid from a panther (voiced by Ben Kingsley) and a care-free bear (voiced by Bill Murray), Mowgli meets a ton of new jungle animals. A few of which include a slithery python and a friendly ape. Along his way, Mowgli learns valuable lessons about life in this movie full of fun and adventure.

check whether x² +4x +4 is prefect spuare expression or not . if so factorise the expression
Answer:
It is a perfect square expression.
It factors to (x+2)^2
===========================================================
Explanation:
The general format for a perfect square is
(a+b)^2 = a^2 + 2ab + b^2
Which can be seen through the use of the FOIL rule.
Compare x^2+4x+4 with a^2+2ab+b^2, and we have these three equivalences:
x^2 = a^2 .... first terms4x = 2ab .... middle terms4 = b^2 .... last termsSince x^2 = a^2, we can apply the square root to both sides to get a = x. Similarly, 4 = b^2 leads to b = 2. We could get b = -2, but that would mean 2ab = 2x*(-2) = -4x instead of 4x. So we'll stick with b = 2 instead.
Because a = x and b = 2, we then can say:
(a+b)^2 = a^2 + 2ab + b^2
(x+2)^2 = x^2 + 2*x*2 + 2^2
(x+2)^2 = x^2 + 4x + 4
Showing that x^2+4x+4 factors to (x+2)^2.
