Answer:
c = 5
Step-by-step explanation:
The slope is the change in y over the change in x. Or as I memorized RISE OVER RUN. Also in physics, you can write ∆y/∆x. Delta (∆) just means change.
Using this equation we have
The slope = m = 3 = ∆y/∆x
m = (-1 - c)/(-8 - -6) = (-1 - c)/(-8+6) = (-1 - c)/(-2) = 3
Now multiply both sides of the equation by -2 and you get
(-1 - c) = 3•(-2) = -6
Almost there!
Now we have the equation
-1 - c = -6
Add one to both sides and you get
-1+1-c = -6 +1
Simplified that equals
-c = -5
Then to get our answer we have to go from negative to positive.
Multiplying both sides by -1 we get
-1 • -c = -1 • -5
c = 5
Now CHECK!
Plug c into the equation ∆y/∆x and you get a slope of 3 which proves the answer is right.

Answers

the area of triangle formula is A = B*H / 2 so it means 16 square = (x+4) x /2 so x²+4x -32=0, D' = 2²- (-32)= 36, sqrt of D' = 6 so x = -2 -6 = -8 or x= -2 +6 = 4 x must be positive so x = 4

If f(x)=16x-30 and g(x)=14x-6, for which value of x does (f-g)(x)=0?

Answers
The value of x for which (f - g)(x) = 0 is x = 12.
To find the value of x for which (f - g)(x) = 0, we need to subtract g(x) from f(x) and set the resulting expression equal to zero. Let's perform the subtraction:
(f - g)(x) = f(x) - g(x)
= (16x - 30) - (14x - 6)
= 16x - 30 - 14x + 6
= 2x - 24
Now, we can set the expression equal to zero and solve for x:
2x - 24 = 0
Adding 24 to both sides:
2x = 24
Dividing both sides by 2:
x = 12
Therefore, the value of x for which (f - g)(x) = 0 is x = 12.

f (x) = cx + 3
In the function above, c is a constant. If f (1) = 1, what is the value of f (-4) ?
Answers
If f(1) = 1 that means c is -2 because when you substitute x = 1 and when c = -2, you'll get f(1) = -2(1)+3 = -2+3 = 1
So the constant c is -2 and that means the value of f(-4) is
f(-4)=-2(-4)+3=8+3=11
Thus, the value of f(-4) is 11.
About why does "c" have to be -2, here's the proof.
Given y = f(x), therefore.
y=cx+3
Since when x = 1 and y = 1, then Substitute x = 1 and y = 1, thus 1 = c+3
1 - 3 = c and therefore, -2 = c #
So this is the proof that c = -2

Find the length in feet of a leg of a right triangle whose hypotenuse is 10 feet and
other leg is 48 inches. Round to the nearest tenth of a foot.
Answers
Answer:
9.2 feet
Step-by-step explanation:
Start by converting the leg of the triangle to feet (note 1 foot = 12 inches):
\(48\ inches(\frac{1\ foot}{12\ inches})=4*1\ foot=4\ feet\)
We can use the Pythagorean Theorem to find the length of the other leg...
\(a^2+b^2=c^2\)
Note that "a" and "b" represent the two legs of the triangle and "c" represents the length of the hypotenuse. We can substitute the given lengths into the equation to solve for the other leg.
\(4^2+b^2=10^2\\16+b^2=100\)
Subtract 16 from both sides:
\(b^2=84\)
Take the square root of both sides:
\(b=\sqrt{84}\\b\approx9.2\ feet\)
Marcus is making homemade barbecue sauce. The recipe calls for 3 cups of ketchup for every 1/2 cup of mustard. What is the rate in cups of ketchup per cup of mustard?
Answers
Answer: 6 cups of ketchup per cup of mustard
Step-by-step explanation:
Given : The recipe calls for 3 cups of ketchup for every \(\dfrac12\) cup of mustard.
That means , for \(\dfrac12\) cup of mustard. we need 3 cups of ketchup.
By using proportions, if we multiply 2 on both sides ,we get
for \(\dfrac12\times 2\) cup of mustard. we need \(3\times 2\) cups of ketchup.
⇒ for \(1\) cup of mustard. we need \(6\) cups of ketchup.
Hence, the required rate = 6 cups of ketchup per cup of mustard
The rate in cups of ketchup per cup of mustard is 6.
Given that,
The recipe calls for 3 cups of ketchup for every 1/2 cup of mustard.Based on the above information, the calculation is as follows:

This is the same as y = - (√x) - 3
- 3 means the function is translated 3 units down since it is negative.

Option B is Correct. An specific place in space is called a point. A dot indicates a point.
A point in space is a location. No length, width, or thickness exist in a point. In geometry, a dot stands in for a point. We typically use a (capital) letter to name a point. The simplest basic geometric object is a point. It is named with a capital letter and symbolised by a dot.
A point has no size and solely represents position (that is, zero length, zero width, and zero height). In a line, a line segment has two distinct endpoints. The line segment's length, which is the separation of two fixed points, is constant.

Hailey is the oldest of four siblings whose ages are consecutive integers. If the sum of their ages is 66, find Hailey's age.
Answers
Considering the definition of an equation and the way to solve it, Hailey's age is 18 years.
Definition of equationAn equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.
The members of an equation are each of the expressions that appear on both sides of the equal sign while the terms of an equation are the addends that form the members of an equation.
The solution of a equation means determining the value that satisfies it. In this way, by changing the unknown to the solution, the equality must be true.
To solve an equation, keep in mind:
When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.Hailey's ageBeing "x" the age of the youngest child, then you have:
"x" the age of the youngest child."x + 1" the age of one middle child."x + 2" the age of the other middle child."x + 3" the age of the oldest child, in this case Hailey's age.On the other hand, you know that the sum of their ages is 66. Then, the equation is:
x + x + 1 + x + 2 + x + 3 = 66
Solving:
4x + 6 = 66
4x = 66 - 6
4x = 60
x= 60 ÷ 4
x= 15
Remembering that "x + 3" is Hailey's age, then her age is calculated as: x+3= 15 +3= 18
Finally, Hailey's age is 18 years.

A plumber needs to replace 20 feet of copper piping . When he gets to the supply store , the lengths are given in meters . How many meters of piping does he need to purchase ?
Answers
Answer:
6.096 m
Step-by-step explanation:
We need to convert 20 ft into meters.
We can use these conversions:
1 ft = 12 in.
1 in. = 2.54 cm
100 cm = 1 m
20 ft * (12 in.)/(1 ft) * (2.54 cm)/(1 in.) * (1 m)/(100 cm) = 6.096 m
Answer: 6.096 m
Answer:
7 meters.
Step-by-step explanation:
I say 7 meters, because a meter is around 3 feet so to get to 20 feet you would buy 7 meters of copper piping to get a total of 21 feet which is close to 20 feet.

a + b =c a + b + c = 36 given that a and b have the same value what is a,b and c
Answers
Answer:
a = 9 b = 9 c = 18
Step-by-step explanation:
a+b = c
a+ b + c = 36 but we know a+b = c sub that in
c + c = 36
c = 18 now a + b = c and a and b are the same
so a and b are = 9
Answer:
a is 9
b is 9
c is 18
Step-by-step explanation:
Let's list the information provided
a + b =c
a + b + c = 36
a=b
Knowing that a=b we can replace b with a in the equations
a+a is the same as 2a since a is being doubled
2a=c
Knowing this we can replace c with 2a
2a+2a=36
Now solve for a
\(2a+2a=36\\4a=36\\\frac{4a}{4} =\frac{36}{4} \\a=9\)
Now let's sub this value of a into the equations to see what the other values are
a=b
9=b
2a=c
2(9)=c
18=c
