Answer:
y = [tex]\frac{1}{3}[/tex] x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = [tex]\frac{1}{3}[/tex] , then
y = [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c substitute (3, - 2) into the partial equation
- 2 = 1 + c ⇒ c = - 2 - 1 = - 3
y = [tex]\frac{1}{3}[/tex] x - 3 ← equation of line
Write the equation of the circle with a center at (11,6) and a radius of 6.
Answer:
(x-11)^2 + (y-6)^2= 6^2
Step-by-step explanation:
Answer:
(x - 11)² + (y - 6)² = 36
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (11, 6 ) and r = 6, then
(x - 11)² + (y - 6)² = 6² , that is
(x - 11)² + (y - 6)² = 36

Three line segments have measures of 17 units, 11 units and 12 units. Will the 1 point
segments make a triangle? *
O No
O Yes
Answer:
No
Step-by-step explanation:
The smaller amounts (11 and 12) have to add to be equal to or greater than the larger amount (17).
Hope it helps!
Answer:
No
Step-by-step explanation:
Because the formula for finding the hypotenuse of a triangle is a^2+b^2=c2.
so it will be 11^2 + 12^2 = c^2

550.3^ x = 50
Answer:
- 2.18
Step-by-step explanation:
550 × [tex]3^{x}[/tex] = 50
[tex]3^{x}[/tex] = [tex]\frac{1}{11}[/tex]
[tex]log_{3}[/tex] [tex]\frac{1}{11}[/tex] = x
x = [tex]log_{3}[/tex] 1 - [tex]log_{3}[/tex] 11
[tex]log_{3}[/tex] 1 = 0
[tex]log_{3}[/tex] 11 = 2.1826583386
x ≈ - 2.18

Find the solution to the system. Write your solution as an ordered pair (x,y) with no spaces, no solution, or infinitely many. x=2y-7 and 4x+y=71 *
Answer:
The solution is (15, 11) There is only one solution.
Step-by-step explanation:
Solve this system using substritution. In the second equation replace x with 2y - 7, obtaining:
4(2y - 7) + y = 71, which simplifies as follows:
8y - 28 + y = 71, or
9y = 99. then y must be 11. If y is 11, then x = 2y - 7, or x = 2(11) - 7 = 15
The solution is (15, 11) There is only one solution.
Reparte 280 euros entre 3 personas, de forma que la 1º reciba el triple que la 2º y esta el doble de la3º
Answer:
x = 31.11
Step-by-step explanation:
Let us assume the third person receives be x
Now the second person receives be 2x
And, the second be 3(2x) = 6x
The total is 280
Now the equation is
x + 2x + 6x = 280
9x = 280
x = 31.11

(7th grade math)
help is very much appreciated :)
Answer:
If we are working with numbers 26m, 24m, 20m, 26m, 39m
Than the surface area of the shape would be 0.24
Work:
3.46 × 106 = 366.76
366.76 + 20 =386.76
386.76 in square meters is 0.24

Michael is saving to buy his senior ring. The base cost of the ring is $280. There are also upgrades he can purchase for the ring. If he saves $35 each month, Which solution represents how many months it will take Micheal before he can purchase his ring?
A.x<_8
B.x_>8
C.x<8
D.x>8
Answer:
B
Step-by-step explanation:
Assuming that he doesn't buy any upgrades it will take 280/35 = 8 months to save enough money to buy the ring. Taking the possibility that he may buy an upgrade too we can say that it will take 8 months or more to buy the ring.
When n = 3, which of the expressions below will be greater than 50? Select all that apply. A) (8n2÷9)⋅7 B) 2n2⋅3 –4n C) 4n2–6n+12 D) 7n+(n⋅8)
Answer:
A
Step-by-step explanation:
a)
[tex](8(3)^{2} / 9) * 7[/tex]
8(9) / 9 = 8 x 7 = 56
b)
[tex]2(3)^{2} * 3 - 4(3)[/tex]
2(9) * 3 - 12
18 * 3 = 54 - 12 = 42
c)

factorise 21ax+10by-35ay-6bx
with working pls
Answer:
( 7a - 2b ) ( 3x - 5y )Step-by-step explanation:

21ax - 35ay - 6bx + 10by
7a ( 3x - 5y ) - 2b ( 3x - 5y )

Can someone tell me what Pythagorean theorem is? I really need help.
Answer:
The sum of the squares of the two sides equals the square of the hypotenuse (a² + b² = c²).
Let's say you have a triangle with a 90º angle (also known as a right angle). The two equal legs are a and b while the hypotenuse is the longer side. Hypotenuse is and always will be c.
Here's a problem:
c ⊿ a (12)
b (6)
C is missing, we have to find C, so here's what we do:
Step 1: You square all the numbers in the equation
12² + 6² = c²
↓
144 + 36 = c
Step 2: You add 144 + 36 and you get 180
Step 3: Then you find the square root >> [tex]\sqrt{180\\[/tex] and you get ≈13.4
Now sometimes, the a or b would be missing, for example:
c (13)⊿ a
b (5)
A is missing (when a or b is missing, use the following formula, do not use the same formula when c is missing)
Step 1: You square all the numbers in the equation
a² + 5² = 13²
a + 25 = 169
For this next part, you must subtract a or b (in this case, b) on both sides, for example:
25 – 25 = 169 - 25
25 – 25 cancels itself out so now we subtract 169 by 25 and we get 144.
Then we find the square root of 144 and we get 12
I hope this helps :)

The slope of a line Ax + By + C = 0 is
A. m = A/B
B. m = -A/C
C. m = B/A
D. m = -A/B
Find the equation of the line. Use exact numbers y=, x,+5
I can't see pictures, so I'll do my best.
y= always stays the same.
To find the slope, or x, you have to start at the y-intercept, and find the number of units up, then right.
For example, y=4/3+6
4/3 is the slope because it goes up 4 units and right 3 units from the y-intercept.
6 is the y-intercept, which is the y-coordinate. It can also be graphed as (0,6).

What is the surface area of this cylinder?
Answer:
1067.6 m²Step-by-step explanation:
Given that
r = 10 mh = 7 mπ ≈ 3.14Find the surface area of the cylinder!
Equation =
2πr × (r+h) =(2 × 3.14 × 10) × (10 + 7) =
62.8 × 17 ≈
1067.6 m²The surface area of the cylinder ≈ 1067.6 square metres
_________________
#Indonesian - kexcvi
Answer:
Use this formula to calculate for the surface area of cylinder.
Step-by-step explanation:
A=2π r h+2 π r^2.
use r = 10 m and h = 7 m
2 (3.14) (10) 7 + 2 (3.14) 10 ^2. = 439.6 + 628 = 1067.6
round to the nearest hundredths = 1068
Why does -2^6 equal -64 but -2 x -2 x -2 x -2 x -2 x -2 equal 64?
(The x's are multiplication)
Answer:
when there are no parentheses around the base, this being -2 we put parentheses around the the 2 and the exponent so it will look like -(2^6) making whatever answer you get negative.
when you put parentheses around the base (-2)^6 you will get 64

One hundred and twenty-two AFLP markers were mapped using an IR64 x Azucena rice doubled-haploid (DH) population. The distribution of these mapped markers was monitored across a set of 48 diverse landraces of rice. Strong statistical associations were observed between 960 of the 7381 possible pairs of markers across the diverse material.
