What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things. In daily speech, a line segment with two points designating its endpoints is also referred to as a line.
The line is shown below.

Write the equation for a parabola whose vertex is (-6,-1) and passes through (-12,17).
Answer:
[tex]y=\frac{1}{2}(x+6)^2-1[/tex]
Step-by-step explanation:
Equation of the Quadratic Function
The vertex form of the quadratic function has the following equation:
[tex]y=a(x-h)^2+k[/tex]
Where (h, k) is the vertex of the parabola that graphically represents the function, and a is a coefficient different from zero.
The vertex of the required equation is located at (-6,-1)
The parabola passes through (-12,17)
Substituting the coordinates of the vertex, the equation of the function is:
[tex]y=a(x+6)^2-1[/tex]
The value of a will be determined by using the given point:
[tex]17=a(-12+6)^2-1[/tex]
Operating:
[tex]17=a(36)-1[/tex]
[tex]36a=18\Rightarrow a=18/36=1/2[/tex]
Solving:
[tex]a=1/2[/tex]
The equation of the parabola is:
[tex]\boxed{y=\frac{1}{2}(x+6)^2-1}[/tex]
At a candy store, Jeremiah bought 1 pound of jelly beans for $9. Meanwhile, Emma bought 4
pounds of jelly beans and 6 pounds of gummy worms for $60. How much does the candy
cost?
Plz help ASAP
Answer:
I think the candy cost 51 dollars
Jellybeans: 36$
Gummy worms: 15$
36 + 15 = 51
Step-by-step explanation:
Since jeremiah bought 1 pound for 9 dollar you can minus 9 from the equation which is 51 and since each pound of jelly beans were 9 dollars 9 x 4 = 36 and 51 - 36 is 15 so the cost of the gummy worms are 15 so
either 51 or 36 and 15

PLEASE HELP!! If f (x) = 4x^-2 + 1/4x^2 + 4, then f’(2) =
Work Shown:
f(x) = 4x^(-2) + (1/4)x^2 + 4
f ' (x) = 4*(-2)x^(-3) + (1/4)*2x .... power rule
f ' (x) = -8x^(-3) + (1/2)x
f ' (2) = -8(2)^(-3) + (1/2)*(2)
f ' (2) = 0
Finding the derivative, we have that f'(2) = 0, option D.
-----------------------------
The derivative of an exponent is:[tex](x^n)^{\prime} = nx^{n-1}[/tex]
Additionally, the sum of the derivatives is the derivative of the sum. The derivative of a constant is zero.-----------------------------
The function is:
[tex]f(x) = 4x^{-2} + \frac{x^2}{4} + 4[/tex]
The derivatives are:
[tex](4x^{-2})^{\prime} = -2 \times 4x^{-2 -1} = -8x^{-3}[/tex]
[tex](\frac{x^2}{4})^{\prime} = \frac{2x}{4}[/tex]
[tex](4)^{\prime} = 0[/tex]
Thus, the derivative of the function is:
[tex]f^{\prime}(x) = -8x^{-3} + \frac{2x}{4} = -\frac{8}{x^3} + \frac{2x}{4}[/tex]
At x = 2:
[tex]f^{\prime}(2) = -\frac{8}{2^3} + \frac{2(2)}{4} = -1 + 1 = 0[/tex]
Thus f'(2) = 0, option D.

Using the figure below, find the measure of z ( just enter in the number for your answer don’t worry about the degree symbol or saying “ degrees” after the number
Answer:
z = 29°
Step-by-step explanation:
We know that the 3 angles in a triangle always add up to 180°. So for triangle ABC, angle A = 59° (given), and angle B = 43° + 49° = 92° (given).
angle A + angle B + angle C = 180°
59° + 92° + z = 180°
151° + z = 180°
Subtract 151° from both sides of the equation
z = 180° -151°
z = 29°

Answer:
(-1.6)(3 + 0.1)
Step-by-step explanation:
Sidney applied the steps to find the product of two numbers (3.1) and (-1.6),
Step 1,
(3.1)(-1.6) = (-1.6)(3.1)
Step 2,
(-1.6)(3.1) = (-1.6)(3 + 0.1)
Step 3,
(-1.6)(3 + 0.1) = -4.8 + (-0.16) [Distributive property]
Step 4,
-4.8 + (-0.16) = -4.96
Therefore, expression that correctly fits in step 2 will be,
(-1.6)(3 + 0.1)

Given f(x) = 70 + 11x, find x when f(x) =158
Answer:
[tex] \huge \boxed{x = 8}[/tex]
Step-by-step explanation:
f(x) = 70 + 11x
To find the value of x when f(x) =158 , equate f(x) to 158
We have
[tex]70 + 11x = 158 \\ 11x = 158 - 70 \\ 11x = 88[/tex]
Divide both sides by 11
[tex] \frac{11x}{11} = \frac{88}{11} \\ [/tex]
We have the final answer as
x = 8Hope this helps you
