Y=-1/3x+6 and x=-6 find the solution to the system
Answer:
(- 6, 8 )
Step-by-step explanation:
Given the 2 equations
y = - [tex]\frac{1}{3}[/tex] x + 6 → (1)
x = - 6 → (2)
Substitute x = - 6 into (1) and evaluate for y
y = - [tex]\frac{1}{3}[/tex] × - 6 + 6 = 2 + 6 = 8
solution is (- 6, 8 )
Find the equation of a line that passes through the point (3,6)
with slope 2.
Answer:
y = 2x
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 = 2 , then
y = 2x + c ← is the partial equation
To find c substitute (3, 6) into the partial equation
6 = 6 + c ⇒ c = 6 - 6 = 0
y = 2x ← equation of line
The equation of line that passes through the point (3,6) with slope 2 is;
⇒ y = 2x
Given that;
The point is (3, 6)
The slope of line = 2
We have to find the equation of a line that passes through the point (3,6) with slope 2.
What is equation of line?
The equation of line that passes through the point (x₁, y₁) with slope m is;
y - y₁ = m (x - x₁)
The point is (3, 6)
The slope of line = 2
The equation of line that passes through the point (x₁, y₁) = (3,6)
with slope(m) = 2 is;
y - y₁ = m (x - x₁)
y - 6 = 2 (x - 3)
y - 6 = 2x - 6
Add 6 on both sides;
y = 2x
Hence, The equation of line that passes through the point (3,6) with slope(m) 2 is;
⇒ y = 2x

Answer:
Mean=85.5
Median=82
Mode=82
Range=25
Please would you mind marking me as the brainliest:)
Answer:
Mean: 85
Median: 82
Mode: 82
Range: 25
Step-by-step explanation:
The mean is the average of all of the numbers. You add all of the numbers together and then divide by the total amount of number you have. In this case you have 8 scores. So you add all the scores together, and then divide by 8:
82 + 78 + 82 + 80 + 100 + 96 + 75 + 91 = 684
684/8 = 85.5
So 85 is the mean.
The median is the number that is in the middle of all of the numbers listed. To do this, first list the numbers in order:
75, 78, 80, 82, 82, 91, 96, 100
The two numbers in the middle are both 82. So, 82 is the median.
The mode is the number that appears the most. In this problem, you can see that the number 82 appears twice. So 82 is the mode.
The range is the highest number minus the smallest number. Here, the highest number is 100. The smallest number is 75. So,
100 - 75 = 25
25 is the range.

Answer:
Step-by-step explanation:
Set up a right triangle to reflect the tangent ratio. Tangent is equal to the side opposite the reference angle over the side adjacent to the reference angle. If tangent is 4/3, then the side opposite the reference angle is 4 in length and the side adjacent is 3 in length. The reference angle, just for clarification, is the base angle that is not the right angle. So we have a right triangle with a height of 4 and a base of 3. We need the sin ratio from that. The sin ratio by definition is the side opposite the reference angle over the hypotenuse. But we don't have the hypotenuse. We have to solve for it using Pythagorean's Theorem.
[tex]h^2=4^2+3^2[/tex] and
[tex]h^2=16+9[/tex] and
[tex]h^2=25[/tex] so
h = 5. Now we find the sin ratio to be 4/5 (the side opposite the reference angle over the hypotenuse).

What is the average rate of change for this quadratic function for the interval
from x = 1 to x = 3?
O A. -8
B.-4
O O
C. 8
O D. 4
==========================================================
Explanation:
The table says that when x = 1, the output is y = -2.
So the point (1, -2) is on the parabola.
The table also says that point (3, -10) is on the parabola. We're focusing on this because x = 3 is the other endpoint.
Find the slope of the line through those two points. The slope here is the same as the average rate of change.
m = (y2 - y1)/(x2 - x1)
m = (-10 - (-2))/(3 - 1)
m = (-10 + 2)/(3 - 1)
m = -8/2
m = -4 is the slope, and therefore, the average rate of change from x = 1 to x = 3.

Answer:
y=1/3x+3
Step-by-step explanation:
the general equation for a straight line is y=mx+c.where c is the y cut therefore the y cut on our graph is at (0,3)therefore c is 3
we then find the gradient which is "m" on our equation using the formula m=y2-y1/x2-x1
then we substitute the m and c then tha is the equation.

The volume of the cylinder is 51207 m. What is the missing value? K 20
Answer:
57.11 m
Step-by-step explanation:
The formula for the volume of a cylinder of radius r and length h is
V = πr²h. We want to solve this formula for d, the diameter of the cylinder.
Start by solving the equation V = πr²h for r²: divide both sides by πh.
V
Then r² = -------------
πh
51207 m³
Substituting 20 for h and 3.14 for π, we get r² = ------------------ or:
3.14(20 m)
r² = 815.40 m²
Find the radius by taking the square root of both sides of the previous result:
r = 28.56 m
The diameter is twice the radius, and therefore the diameter here
is d = 2(28.56) m = 57.11 m
Un capital de $10 000 se coloca a una tasa anual de interés compuesto del 6% durante 3 años. Determinar el interés generado Si la capitalización es una vez al año Si la capitalización es una vez al mes
Answer:
(a) $ 1191
(b) $ 1966.8
Step-by-step explanation:
Principal, P= $ 10000
Rate of interest, r = 6 % per year
time, t = 3 years = 36 months
(a) Interest per year
The amount is given by
[tex]A = P \times \left ( 1+\frac{r}{100} \right )^{t}\\\\A = 10000 \times \left ( 1+\frac{6}{100} \right )^{3}\\\\A = 10000 \times 1.191\\\\A = 11910.2[/tex]
Interest is given by = $11910.2 - $10000 = $ 1910.6
(b) interest per month
The amount is given by
[tex]A = P \times \left ( 1+\frac{r}{100} \right )^{t}\\\\A = 10000 \times \left ( 1+\frac{6}{1200} \right )^{36}\\\\A = 10000 \times 1.1967\\\\A = 11966.8[/tex]
Interest paid is = $ 11966.8 - $ 10000 = $ 1966.8

8x-2(x - 5) = x + 25
A. x= 3
B. x= 7
C. x = 6
D. X= 4
Answer:
x=3
Step-by-step explanation:
8x-2(x - 5) = x + 25
Distribute
8x -2x+10 = x+25
Combine like terms
6x +10 = x+25
Subtract x from each side
6x-x +10 = x+25-x
5x +10 = 25
Subtract 10 from each side
5x-10+10 =25-10
5x= 15
Divide each side by 5
5x/5 =15/5
x=3
Answer:
A. x = 3
Step-by-step explanation:
8x- 2(x - 5) = x + 25
Using distributive property
8 x - 2 x - 10 = x + 25
combine like terms
6 x - 10 = x + 25
subtract both side from x
6 x - x - 10 = x - x + 25
5 x - 10 = 25
Add 10 to both side
5 x - 10 + 10 = 25 - 10
5 x = 15
Divide both side by 5
5 x / 5 = 15 / 5
x = 3
