Hello, need help on this Coordinate Math question please (:
Answer:
(8, 3)
Step-by-step explanation:
The first number (8) is our x, and we can see that this point is 8 units to the right. Then the second number (3) is our y, and we can see this is 3 as the point is 3 units up.
x = right or left
- right = positve
- left = negative
y = up or down
- up = positve
- down = negative
Answer:
B = (8, 3)
Step-by-step explanation:
In the ordered pair (x, y) of point B, (8, 3):
x = 8
y = 3

Determine the equation of the line parallel to y=-5x+3 and passing
through the point (-3,7)
Answer:
y = -5x - 8
Step-by-step explanation:
Parallel lines have the same gradient
Using the point (-3,7) we will form our own equation.
-3 will be x, 7 will be y, -5 will be m, all we have to do is find the C in the form y=mx+c
7 = -5(-3) + c
7 = 15 + c
C = -8
Therefore;
y = -5x - 8

What is the slope of the line on the graph?
Answer:
-2
Step-by-step explanation:
To find the slope pick ANY 2 points on the line and see what you had to do to get from one point to another point.
Keep in mind that slope = rise/run , or m = difference in y /difference in x
For example, Start at (0,0) and Go to (6,-3)
To get from one point to the other you have to go up 6 and left 3 so slope is
m=6/-3 = -2

Answer:
16 * (cube root of 0.5)
Step-by-step explanation:
Radius of the big cone = 12 cm / 2 = 6 cm
Let r = radius of the small cone (cone of water), and h = the height of the small cone
Also, r / h = 6 / 16, so that h = (16/6)r = (8/3)r.
Thus, since the volume of the big cone = (1/3)π(r^2*h)=(1/3)π(6^2*16), and the volume of the small cone = (1/3)π(r^2*h)=(1/3)π(r^2*(8/3)r) = (1/3)π(r^3*(8/3)), and the volume of the small cone is half the volume of the big cone, we have that
(1/3)π(r^3*(8/3))=(1/2)((1/3)π(6^2*16))
(r^3*(8/3))=(1/2)((6^2*16))
r^3 = (3/8)(1/2)(6^2)(16)
r^3 = (1/2)(6^3)
r = (cube root of 1/2)(6),
and
h = (8/3)r = (8/3)(cube root of 1/2)(6) = 16(cube root of 1/2), the depth of the water.

y = 6x -11
-2x - 3y = -7
Answer:
x = 2
y = 1
Step-by-step explanation:
1) Re-arrange
(Solving for y)
-2x -3y = -7 --> x3
6x - y = 11 --> x1
-6x -9y = -21
6x -y = 11
-9y = -21
-y = 11
(-9y + -y) = (-21 + 11)
-10y = -10
y = -10/-10
y = 1
2) Substitute
6x - 1 = 11
6x = 11 + 1
6x = 12
x = 12/6
x = 2
Answer: x = 2, y = 1
Step-by-step explanation:
Rearrange the second equation so it just works a little easier for you:
-2x - 3y = -7
rearranged to make y (with its constant) the subject:
3y = 7 - 2x
So we know what y equals. The question tells us y = 6x - 11. So substitute those values into the rearranged equation.
3y = 7 - 2x becomes:
3(6x - 11) = 7 - 2x
because as stated in the question, y = 3x - 11.
Expand the brackets on the left-hand side:
18x - 33 = 7 - 2x
Rearrange to collect like terms:
18x = 7 + 33 - 2x
18x = 40 - 2x
18x + 2x = 40
20x = 40
x = 40/20
x = 2.
So now we know the value of x.
Let's input our new found value of x into one of the given equations, such as y = 6x - 11.
y = (6 * 2) - 11
y = 12 - 11
y = 1.
So y = 1.
You can test this by inputting these values into the other equation, for assurance.
-2x - 3y = -7 becomes:
(-2 * 2) - (3 * 1) = -7
(-4) - 3 = -7
-7 = -7

1)what is the value of this expression? 4m + 2n, when m = 7 and n = -2
2) Use the formula: P=abc, to work out for P when a = 2, b= 3 , c =4
3)what is the correct option (expression) for this “multiply n by 9 then adds 5’’?
options
a: 9(n+5)
b: 9n + 5
c: 5n + 9
d: 5(n+9)
4)use the position -to-term rule to find the first four terms in the sequence. term = 3x position number + 3
5) amy thinks of. number n. what is the correct expression if she doubles ur and -‘s 7
Answer:
Step-by-step explanation:
1) 4m + 2n = 4*7 + 2*(-2)
= 28 - 4
= 24
2) P = abc
= 2*3*4
= 24
3) Multiply n by 9 : 9*n = 9n
Then add 5
9n + 5
4)double of n = 2*n = 2n

Answer:
12 11/24 radians (combined angular motion)
Step-by-step explanation:
In one hour, the combined angular motion is ...
(2π)(1 +1/12) = 13π/6 radians
Then in the 5 3/4 hours between 1 pm and 6:45 pm, the angular motion of the two hands will total ...
(23/4)(13π/6) radians = 299π/24 radians = 12 11/24 radians
_____
Additional comment
Maybe you're asking for the separate motions.
minute hand: 2π×5.75 = 11.5π radians
hour hand: (π/6)×5.75 = 23π/24 radians
