Solve the system by substitution.
x=-6y 4x + 10y = 14
Answer:
x = 6
y = -1
Step-by-step explanation:
x = - 6y ----------------------(I)
4x + 10y = 14 ------------------(II)
Substitute x = -6y in equation (II)
4*(-6y) + 10y = 14
-24y + 10y = 14 {Combine like terms}
-14y = 14 {Divide both sides by 1-4}
y = 14/-14
y = -1
Now, substitute y = -1 in equation (I)
x = - 6*(-1)
x = 6

1. $27.30 2. $48.00 3. $15.75 4. $24.20 5. $31.00 6. $40.80
Step-by-step explanation:
1. $13.00 + (1.10)($13.00)
= $ 27.30
2. $60.00 - $60.00(0.20)
= $48.00
3. $15.00 + $15.00(0.05)
= $15.75
4. $22.00 + $22.00(0.10)
= $24.20
5. $25.00(0.06) + $25.00(0.18) + $25.00
= $31.00
6. $32.00(0.075) + $32.00(0.20) + $32.00

Answer:
300 degrees
Step-by-step explanation:
After converting the given equation 5π/3 into degree, the value obtained will be equal to 300°.
What is an expression?If a mathematical operation includes at least two words that are connected by an operator and either comprise numbers, variables, or both, it is referred to as an expression.
The operations with reflection coefficients include adding, subtracting, multiplying, and dividing. In order to include terms into an expression, a mathematical operation like reduction, addition, multiplication, or division is used.
As per the given information in the question,
5π/3 radians to degree.
To convert radians to degree multiply it with 180/π
So,

Answer:

Step-by-step explanation:
the straight line L passes through the points (0 , 12) and (10 , 4).
Find an equation of the straight line which is parallel to L and passes through the point (5 , -11).
Answer:
y = - [tex]\frac{4}{5}[/tex] x - 7
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 )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 12) and (x₂, y₂ ) = (10, 4)
m = [tex]\frac{4-12}{10-0}[/tex] = [tex]\frac{-8}{10}[/tex] = - [tex]\frac{4}{5}[/tex] ← slope of line L
Parallel lines have equal slopes , then
y = - [tex]\frac{4}{5}[/tex] x + c ← is the partial equation
To find c substitute (5, - 11) into the partial equation
- 11 = - 4 + c ⇒ c = - 11 + 4 = - 7
y = - [tex]\frac{4}{5}[/tex] x - 7 ← equation of parallel line
The equation of the straight line which is parallel to L and passes through the point (5 , -11) will be;
⇒ y = - 4/5x - 7
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The straight line L passes through the points (0 , 12) and (10 , 4).
And, The equation of the straight line which is parallel to L and passes through the point (5 , -11).
Now,
Since, The straight line L passes through the points (0 , 12) and (10 , 4).
So, Equation of line L is,
⇒ y - y₁ = (y₂ - y₁) / (x₂ - x₁) (x - x₁)
⇒ y - 12 = (4 - 12) / (10 - 0) (x - 0)
⇒ y - 12 = - 8 / 10x
⇒ 10 (y - 12) = - 8x
⇒ 10y - 120 = - 8x
⇒ 10y = - 8x + 120
⇒ y = - 8/10x + 12
⇒ y = - 4/5x + 12
And, The equation of the straight line which is parallel to L and passes through the point (5 , -11).
So, We need to find the slope of the line.
Since, The slope of the parallel line is same.
Hence, Slope of the line is,
y = -4/5x + 12
m = dy/dx = - 4/5
m = - 4/5
Thus, The equation of line with slope 1- 4/5 is,
⇒ y - (-11) = - 4/5 (x - 5)
⇒ y + 11 = - 4/5 (x - 5)
⇒ 5 (y + 11) = - 4x + 20
⇒ 5y + 55 = - 4x + 20
⇒ 5y = - 4x + 20 - 55
⇒ 5y = - 4x - 35
⇒ y = - 4/5x - 7
Thus, The equation of the straight line which is parallel to L and passes through the point (5 , -11) will be;
⇒ y = - 4/5x - 7

HELP PLS: A store receives a shipment of 5,000 MP3 players. In a previous shipment of 5,000 MP3 players, 300 were defective.
A store clerk generates random numbers to simulate a random sample of this shipment. The clerk lets the numbers 1
through 300 represent defective MP3 players, and the numbers 301 through 5,000 represent working MP3 players.
The results are given.
13 2,195 3,873 525 900 1 67 1,094 1,472 709 5,000
Based on the sample, how many of the MP3 players might the clerk predict would be defective?
Answer: 1,000 players
Step-by-step explanation: The result has two values between 1 through 300
out of the 10 value in the sample so the clerk would predict 5,000 *[tex]\frac{2}{10}[/tex]=1,000 defective players.

Answer:
Boys: 2/17
Girls: 4/17
Step-by-step explanation:
2 + 15 = 17 (to get the total number of boys in Sapphire's class)
4 + 13 = 17 (to get the total number of girls in the class)
The proportion is how many who are left handed over the total number of girls/boys. ^^
So, left-handed for boys = 2, which makes the proportion 2/17
And there are 4 left-handed girls, so the proportion is 4/17

For slopes its rise over run but for this question its...... TO BE CONTINUED LOL (go to the explanation)
Step-by-step explanation:
So for the run on the x axis its 7 you can see it goes upward a little bit on the 7 but the 7 still counts :D
ok so we got 7 and as the line rises 9go to the picture added for more understanding) So as the line rises we can see from were i marked it in the picture that it touches the 2. So we got 2 as the rise and 7 as the run but remember this is not slopes lol so its kinda different.

You pay $3 per square foot for carpeting. Which equation can be solved to find the
amount you will pay to cover a triangular section of the floor with a base of 2 yards and
a height of 5 yards?
Answer:
$135
Step-by-step explanation:
Step 1
Conversion
Base = 2 yards
1 yard = 3 feet
2 yards = x
Cross Multiply
x = 2 × 3 feet = 6 feet
Height = 5 yards
1 yard = 3 feet
5 yards = x
Cross Multiply
x = 5 × 3 feet = 15 feet
Step 2
Find the area of the triangle
Area of a triangle = 1/2 × base × height
Base = 6 feet
Height = 15 feet
Area = 1/2 × 6 × 15
= 45 square feet
Step 3
Find the cost of the carpet
1 Square foot = $3
45 square feet = x
Cross Multiply
x = 45 × $3
x = $135
Therefore, the amount you will pay to cover a triangular section of the floor is $135
