y-2 = -3(x + 6), write the equation of the line in slope intercept form.
Answer:
y = -3x - 16
Step-by-step explanation:
Point-slope form: y - y1 = m(x - x1)
Given: y - 2 = -3(x + 6)
Slope-intercept form: y = mx + b
To write the equation in slope-intercept form, we need to know the slope(m) and the y-intercept(b). By looking at the given equation, we can see that the slope is -3. We are also given the value of one point: (-6, 2).
To find the y-intercept, input the given values of the slope and the point into the equation format and solve for b:
y = mx + b
2 = -3(-6) + b
2 = 18 + b
Subtract 18 from both sides of the equation to isolate b:
2 - 18 = 18 - 18 + b
-16 = b
The y-intercept is -16.
Now that we know the slope and the y-intercept, we can write the equation:
y = -3x - 16

6 − 4v = 3 − v
Answer: = 1
Step-by-step explanation: 6−4v=3−v
Step 1: Simplify both sides of the equation.
6−4v=3−v
6+−4v=3+−v
−4v+6=−v+3
Step 2: Add v to both sides.
−4v+6+v=−v+3+v
−3v+6=3
Step 3: Subtract 6 from both sides.
−3v+6−6=3−6
−3v=−3
Step 4: Divide both sides by -3.

Please look at number 10. from the slope and write the equation for me
Answer:
y = 8x + 38
Step-by-step explanation:
To find the slope we set up y = mx + b and plug m (our slope) in and then plug in the point into x and y to find b (our y-intercept)
y = mx + b
y = 8x + b
6 = 8(-4) + b
6 = -32 + b
+32 +32
38 = b
So using our slope and our intercept we have our slope intercept
y = mx + b
y = 8x + 38
Hope this helps :)
Answer:
y - y1 = m(x - x1)
y - 6 = 8(x - (-4))
y - 6 = 8(x + 4)
y - 6 = 8x + 32
y = 8x + 32 + 6
y = 8x + 38
Step-by-step explanation:
First you input the given values ( m = 8 and (-4, 6)) into the point-slope equation.
After that, you multiply the 8 by the two terms inside the parentheses, giving you 8x and 32.
Then you add 6 to both sides of the equation to isolate the y.
The slope-intercept equation ends up looking like this: y = 8x + 38
Hope this helps :)

HG = 28
Step-by-step explanation:
The midsegment MN is half the sum of the 2 parallel bases, that is

Graph the equation
y-3=-3/2(x+4)
Answer: x = (-2,0) y = (0,-3) slope is -3/2
Step-by-step explanation: graph the line by using the slope and y intercept
The graph for the points (0, -3) and (2, -6) is plotted on the graph below.
The given equation is y-3= -3/2(x+4).
What is the graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.
Graph the line using the slope and y-intercept, or two points.
Slope: -3/2
y-intercept: (0, -3)
Plot the points (0, -3) and (2, -6) on the graph
To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
x-intercept(s): (−2,0)
y-intercept(s): (0,−3)
Therefore, the graph for the points (0, -3) and (2, -6) is plotted on the graph below.

Parker owns a food truck that sells tacos and burritos. He sells each taco for $3.25 and each burrito for $7. Yesterday Parker made a total of $552 in revenue from all burrito and taco sales and there were twice as many burritos sold as there were tacos sold. Write a system of equations that could be used to determine the number of tacos sold and the number of burritos sold. Define the variables that you use to write the system.
Answer:
let t= the number of tacos sold
let b= the number of burritos sold
3.25t+7b=552
b=2t
Step-by-step explanation:
Since there were twice as many burrito sold as tacos sold, there were more burritos sold, so if we multiply by 2 the number of tacos sold, we will get the number of burritos sold, meaning b=2t.
The system of equation should be considered as the 3.25t+7b=552 and the value of b should be equivalent to 2t.
Calculation of the equation:here we assume that
t= the number of tacos sold
And, b= the number of burritos sold
As per the situation, the equation be like
3.25t+7b=552
b=2t
So,
put b value in the first equation
3.25t + 14t = 552
t = 3.01
And, b = 1.51

Is X +3 a factor of 2X squared minus 2X -12
Answer: No, x+3 is not a factor of 2x^2-2x-12
========================================================
Explanation:
Let p(x) = 2x^2 - 2x - 12
If we divide p(x) over (x-k), then the remainder is p(k). I'm using the remainder theorem. A special case of the remainder theorem is that if p(k) = 0, then x-k is a factor of p(x).
Compare x+3 = x-(-3) to x-k to find that k = -3.
Plug x = -3 into the function
p(x) = 2x^2 - 2x - 12
p(-3) = 2(-3)^2 - 2(-3) - 12
p(-3) = 12
We don't get 0 as a result so x+3 is not a factor of p(x) = 2x^2 - 2x - 12
----------------------------------------
Let's see what happens when we factor p(x)
2x^2 - 2x - 12
2(x^2 - x - 6)
2(x - 3)(x + 2)
The factors here are 2, x-3 and x+2

If 20% is the greatest possible markdown the store can give without losing money, then the price of the dishwasher is $761.60
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that the Sales price = $952
Markdown % = 20%
The Sales price = (100 - 20)% x $952
The Sales price = 80% x $952
The Sales price = $761.60
If 20% is the greatest possible markdown the store can give without losing money, then the price of the dishwasher is $761.60

Answer:
France's GDP is 50 000 times larger than Tuvalu's GDP.
Step-by-step explanation:
Given: Gross Domestic Product (GDP) of France = $2.0 x [tex]10^{12}[/tex]
Gross Domestic Product (GDP) of Tuvalu = $4.0 x [tex]10^{7}[/tex]
To determine the number of times in which the GDP of France is greater than that of Tuvalu, divide the GDP of France by the GDP of Tuvalu.
[tex]\frac{2.0*10^{12} }{4.0*10^{7} }[/tex] = [tex]\frac{2000000000000}{40000000}[/tex]
