Answer: -6x
Step-by-step explanation: Since when x is 0, the function's output is 0, the function can only have terms with x in it. You then notice a pattern that x is always being multiplied by -6. You could also use point slope form to solve it, either way you get f(x)=-6x
Answer:
f(x) = -6x
Step-by-step explanation:
The linear equation given in the form of a table is shown as:
[tex]\left[\begin{array}{ccc}x&f(x)\\0&0\\1&-6\\2&-12\\3&-18\end{array}\right][/tex]
Because the equation is linear, in order to find the equation written in slope-intercept form, divide the rise (f(x)) by the run (x):
0 ÷ 0 = 8
-6 ÷ 1 = 8
-12 ÷ 2 = 8
-18 ÷ 3 = 8
Because the quotient for each relation is -6, the linear equation can be written as f(x) = -6x.
A vertical parabola goes through (-2,-18), (3, -13), and (5, -39). Use matrices to solve for D, E, and F,
given the general form x2 + y2 + Dx + Ey + F = 0 (since it is a vertical parabola there is not a
yż term).
The general formula for the parabola is [tex]x^{2}+y^{2}-21\cdot x +51\cdot y +548 = 0[/tex].
We need the knowledge of three distinct points to determine all coefficients of the vertical parabola based on the following general formula:
[tex]x^{2} + y^{2} + D\cdot x + E\cdot y + F = 0[/tex] (1)
If we know that [tex](x_{1}, y_{1}) = (-2, -18)[/tex], [tex](x_{2}, y_{2}) = (3,-13)[/tex] and [tex](x_{3}, y_{3}) = (5,-39)[/tex], then we have the following system of linear equations:
[tex]-2\cdot D -18\cdot E + F = -328[/tex] (2)
[tex]3\cdot D -13\cdot y + F = -178[/tex] (3)
[tex]5\cdot D -39\cdot E + F = -1546[/tex] (4)
The solution of the system of equations is: [tex]D = -21[/tex], [tex]E = 51[/tex], [tex]F = 548[/tex].
The general formula for the parabola is [tex]x^{2}+y^{2}-21\cdot x +51\cdot y +548 = 0[/tex].

FI h(x) = 3x + 8 , h(a) = 29 then what is the value of a?
Answer:
the value of a = 7..............
Answer:
[tex]h(x) = 3x + 8 \\ h(a) =3 a + 8 [/tex]
But, it is given that
[tex]h(a) = 29[/tex]
Therefore,
[tex]3a + 8 =29 \\ 3a = 29 - 8 \\ 3a = 21 \\ a = \frac{21}{3} \\ \boxed{ a = 7}[/tex]
Hence, the value of a is 7
a = 7 is the right answer.Select the action you would use to solve 3x = 12. Then select the property
that justifies that action.
Select all that apply.
O A. Action: Add 3 to both sides.
B. Action: Multiply both sides by 3.
O C. Action: Divide both sides by 3.
D. Property: Addition property of equality
O E. Property: Multiplication property of equality
F. Property: Division property of equality
Answer:
C. Action: Divide both sides by 3.
F. Property: Division property of equality
Step-by-step explanation:
you are trying to get x by itself so if you divide by 3 you are taking the 3 from x, and what you do to one side you do to the other.
Answer:
C. Action: Divide both sides by 3.
F. Property: Division property of equality.
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.
First, divide 3 from both sides of the equation:
(3x)/3 = (12)/3
x = 12/3
x = 4
C. Action: Divide both sides by 3.
F. Property: Division property of equality.

Ruben, Shelly, and Malcolm have recorded a hit song. Ruben gets 2/5 of the income, Shelly gets 1/3, and Malcolm gets the rest. If they earn $300,000, how much does Malcolm earn?
Answer:
$ 80,000
Step-by-step explanation:
2/5 + 1/3 = (6 + 5)/15 = 11/15
15/15 - 11/15 = 4/15
4/15 of 300,000
4/15 x 300,000 = 1,200,000/15 = 80,000

Find the area of right triangle def,round to nearest tenth if necessary D(-6,-1),E(1,-3),F(3,4)
HELP
Answer:
Step-by-step explanation:
Two of the legs will be at right angles to each other and have negative reciprocal slopes. Area will be half of the product of these two legs.
slope of DE (-3 - (-1)) / (1 - (-6)) = -2/7
slope of EF (4 - (-3)) / (3 - 1) = 7/2
so these two are perpendicular
check the DF line to be certain
slope of DF (4 - (-1)) / (3 - (-6)) = 5/9
Length of DE = √(-2² + 7²) = √53
Length of EF = √(7² + 2²) = √53
Area of triangle
A = ½√53√53 = 26.5 units²
A bird flies at an altitude of 520 feet. A diver dives to a depth of 50 feet below sea level. What is the difference in their elevations? Show how you arrived at your answer.
Answer:
The answer is 570 feet.
Step-by-step explanation:
First, the bird is 520 feet HIGH.
The diver is 50 feet BELOW sea level, which is also -50.
To find the difference, you would SUBTRACT right?
So 520 - -50 OR 520 + 50 (This is because two negatives make a positive, and you are also subtracting negatives, which in turn means adding).
520 + 50 = 570 - HOPE THIS HELPED!

Hello there I think the measure of EBC is 58 degrees.
That's because angles EBC and DBE are complementary. it means that they add up to 90 degrees.
We are given that
DBE=32 degrees.
And we know that angles EBC and DBE add up to 90 degrees.
So we take 90 and subtract the measure of angle DBE (32 degrees)
90-32=58

D. h(x) = 3x - 6
Pls provide an explanation. I need help, and I will mark the person who helps me understand this Brainliest.
Answer:
D
Step-by-step explanation:
We are given the function:
[tex]\displaystyle f(x) = \frac{1}{3} x + 2[/tex]
And we want to find its inverse h.
To find the inverse of a function, we can switch the y and x variables and solve for the new y. This will be our inverse.
We begin with:
[tex]\displaystyle f(x) = y = \frac{1}{3} x+ 2[/tex]
Switching the variables yield:
[tex]\displaystyle x = \frac{1}{3}y + 2[/tex]
And solving for y yields that:
[tex]\displaystyle y = h(x) = 3x - 6[/tex]
In conclusion, the inverse function to f is 3x - 6. Our answer is D.
To understand why we switch the variables, recall that by the definition of inverse functions, if f(a) = b, then f⁻¹(b) = a. So, by switching the variables, we are essentially solving for f⁻¹(x).

Find the derivative of f(x) =4cot(x) + 10 sin(x)

what is 13.6 - x = -64.2
Answer:
13.6 - x = -64.2
Step-by-step explanation:
x = 77.8
13.6 - 77.8 = -64.2 True!
Answer:
x=77.8
Step-by-step explanation:
13.6-x=-64.2
-13.6. -13.6
---------------------
since there is already -x it wouldn't be -77.8 bc that would cancel it out

You should first recognize the shape of the curve - it's an exponential function, so its equation takes the form [tex]y(x)=a\cdot b^{cx}[/tex] for some constants a, b, and c.
The curve lies above the x-axis, so a must be positive.
The curve is defined everywhere (there are no discontinuities), so b must be positive.
As you move left to right, the function is increasing, so c must also be positive. But to make things simpler, let's assume c = 1.
When x = 0, the curve passes through the point (0, 1). In our equation, we have
[tex]y(0) = a\cdot b^0 = a[/tex]
so it follows that a = 1.
When x = 1, the curve approximately passes through the point (1, 4); so
[tex]y(1) = b^1 = 4[/tex]
so b = 4.
Then the equation of the curve might be [tex]\boxed{y = 4^x}[/tex].
