Answer:
y = -13x + 4
Step-by-step explanation:
You want to put it in the form y = mx + b where m is the slope and b is the y-intercept (For example, in the equation y = 2x + 3 the slope is 2 and the y-intercept is 3)
Since the slope is -13, m = -13.
Since the y-intercept is 4, b = 4.
This means the equation is y = -13x + 4

10x + 7y = –8
7x + 7y = –14
Answer:
(2, - 4 )
Step-by-step explanation:
Given the 2 equations
10x + 7y = - 8 → (1)
7x + 7y = - 14 → (2)
Subtract (2) from (1) term by term to eliminate y
(10x - 7x) + (7y - 7y) = - 8 - (- 14) , that is
3x = 6 ( divide both sides by 3 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
10(2) + 7y = - 8
20 + 7y = - 8 ( subtract 20 from both sides )
7y = - 28 ( divide both sides by 7 )
y = - 4
solution to the system of equations is (2, - 4 )
If sin theta= 4/5 and theta is in quadrant 2, the value of cot theta is . if necessary, use the slash mark ( / ) for a fraction bar.
If sin θ= 4/5 and theta is in quadrant 2, the cot θ would be -3/4.
Which trigonometric functions are positive in which quadrant?
In first quadrant (0 < θ < π/2), all six trigonometric functions are positive.
In second quadrant(π/2 < θ < π), only sin and cosec are positive.
In the third quadrant (π < θ < 3π/2), only tangent and cotangent are positive.
In fourth (3π/2 < θ < 2π = 0), only cos and sec are positive.
Given information; If sin θ= 4/5 and theta is in quadrant 2, we need to find the value of cot theta.
Since it’s in second quadrant, cos is going to be negative.
So, a^2 + 4^2 = 5^2
a^2 + 16 = 25
a^2 = 25 - 16 = 9
a = 3
therefore, we can conclude that cos θ = base / hypotenuse
cos θ =-3/5
Also, tan θ would be -4/3 and then cot θ would be -3/4.

Gwendolyn is asked to solve the equation −4(x−3)=20. She shows the work below and states that the solution is x=−8. −4(x−3)=20−4x+12=20−4x=32x=−8 Unfortunately, Gwendolyn's work is flawed. Explain the flaw in Gwendolyn's work. Determine the correct solution to the equation.
Step-by-step explanation:
The equation is given as;
−4(x−3)=20
Gwendolyn's flaw is in the following lines;
−4x + 12 = 20
−4x = 32
When collecting like terms, the moment 12 crosses over, it becomes - 12 and not + 12
The correct solution is given as follows;
Step 1: Expand the brackets
This results to;
- 4x - (-4 * 3) = 20
-4x + 12 = 20
Step 2: Collect like terms
This results to;
- 4x = 20 - 12
- 4x = 8
Step 3: Solve for x
x = 8 / (-4)
x = -2

Answer:
2 50ml bottles
Step-by-step explanation:
Reading through the question, we have:
For 80mL
[tex]C_1 = \pounds 55[/tex]
For 2 50mL bottles.
The cost is calculated by the original cost + half the original cost.
i.e.
[tex]C_2 = \pounds 45 + \frac{1}{2} * \pounds 45[/tex]
[tex]C_2 = \pounds 45 + \pounds 22.5[/tex]
[tex]C_2 = \pounds 67.5[/tex]
Next, is to calculate the unit price of each.
For 80mL
[tex]C_1 = \pounds 55[/tex]
[tex]Unit\ price = 55/80[/tex]
[tex]Unit\ price = 0.6875[/tex]
For 2 50mL bottles.
[tex]C_2 = \pounds 67.5[/tex]
[tex]Unit\ price - 67.5/(2 * 50)[/tex]
[tex]Unit\ price = 67.5/100[/tex]
[tex]Unit\ price = 0.675[/tex]
By comparison, the 2 50mL is the best buy because it has smaller unit price

Ruth Behr has ¾ liters of soda in her refrigerator. She poured 1/8 liter of soda in multiple cups. Enter the number of cups Ruth filled with soda
Answer:
6
Step-by-step explanation:
3/4*8=6
The requried number of Ruth filled with soda is 6 cups.
What is the Ratio?The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Here,
To find the number of cups Ruth filled with soda, we need to divide the amount of soda she poured into cups by the amount of soda in each cup.
Ruth poured 1/8 liter of soda into cups. To convert this to cups, we need to know that 1 liter is equal to 4 cups. So, 1/8 liter is equal to:
(1/8) x 4 cups = 0.5 cups
Ruth has 3/4 liters of soda in her refrigerator, which is equal to:
(3/4) x 4 cups = 3 cups
So, the number of cups Ruth filled with soda is:
= 3 / 0.5
= 6 cups
Thus, the requried number of Ruth filled with soda is 6 cups.

When a job asks you; How many years of Basic Math experience do you have?
you put how many years you've been in school, right? do you include preschool? y or n?
Answer:
All the Years since First Grade
No, you would not include Preschool
Step-by-step explanation:
Technically, for this question, you would put the number of years since you began learning basic math. For the vast majority of children, they begin learning Basic Math such as adding and subtracting whole numbers in First Grade. Therefore, you would include all of the years since First Grade. Preschool usually teaches children about numbers and how to count, as well as develop their social skills. Preschool does not teach basic math because the children are just learning about numbers.

Answer:
x = 180
∠DBC = 23
∠ABC = 157
Step-by-step explanation:
A straight line is always 180 degrees
A to D line = 180
6x + 19 + x = 180
7x + 19 = 180
-19 -19
7x = 161
/ 7 / 7
161 /7 = 23
x = 23
Then plug it in
6x + 19
6 ( 23 ) + 19 = 157

The number $y$ of calories burned after $x$ minutes of kayaking is represented by the linear function $y=4.5x$ . The graph shows the number of calories burned by hiking.
You perform each activity for 45 minutes. How many total calories do you burn?
Answer:
202.5 calories
Step-by-step explanation:
y = 4.5x where y is the calories burned and x is the minutes
Let x = 45 minutes
y = 4.5 * 45
y =202.5 calories
Answer:
The average person burns 375 – 475 calories per hour kayaking.
The number of calories burned kayaking depends on your weight, the distance and speed you kayak, and difficulty of terrain. A 200-pound (90.8kg) person will burn 477 calories per hour kayaking with moderate effort. A 150-pound person will burn 358 calories per hour with the same activity.
