Find the equation (in terms of x) of the line through the points (-4,-4) and (3,1)y=
Answers
In order to find the equation of the line, first let's calculate its slope m using the formula below:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Using the given points (x1, y1) = (-4, -4) and (x2, y2) = (3, 1), we have:
[tex]m=\frac{1-(-4)}{3-(-4)}=\frac{1+4}{3+4}=\frac{5}{7}[/tex]Now, to find the equation, let's use the slope-intercept form and calculate the value of b using a given point:
[tex]\begin{gathered} y=mx+b \\ (3,1): \\ 1=\frac{5}{7}\cdot3+b \\ 1=\frac{15}{7}+b \\ b=1-\frac{15}{7} \\ b=-\frac{8}{7} \end{gathered}[/tex]Therefore the equation is y = (5/7)x - 8/7

Answers
Hello there. To slve this question, we'll have to remembrer some properties about maximum and minimum in a quadratic function.
Given a quadratic function f as follows:
[tex]f(x)=ax^2+bx+c[/tex]We can determine whether or not the vertex is a maximum or minimum by the signal of the leading coefficient a.
If a < 0, the concavity ofthe parabolai is facing down, hence it admits a maximum value at its vertex.
If a > 0, the concavity of the parabola is facing up, hence it admits a minimum value at its vertex.
As a cannot be equal to zero (otherwise we wouldn't have a quadratic equation), we use the coefficients to determine an expression for the coordinates of the vertex.
The vertex is, more generally, located in between the roots of the function.
t is easy to prove, y comlpleting hthe square, that the solutions of the equation
[tex]ax^2+bx+c=0[/tex]are given as
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]Taking the arithmetic mean of these values, we get the x-coordinate of the vertex:
[tex]x_V=\dfrac{\dfrac{-b+\sqrt{b^2-4ac}}{2a}+\dfrac{-b-\sqrt{b^2-4ac}}{2a}}{2}=\dfrac{-\dfrac{2b}{2a}}{2}=-\dfrac{b}{2a}[/tex]By evaluating the function at this point, we'll obtain the y-coordinate of the vertex:
[tex]f(x_V)=-\dfrac{b^2-4ac}{4a}[/tex]With this, we can solve this question.
Given the function:
[tex]y=2x^2-12x+19[/tex]First, notice the leadin coefficient is a = 2 , that is positive.
Hence it has a minimum point at its vertex.
To determine these coordinates, we use the other coefficients b = -12 and c = 19.
Plugging the values, we'll get
[tex]x_V=-\dfrac{-12}{2\cdot2}=\dfrac{12}{4}=3[/tex]Plugging ths value in the function, ewe'll get
[tex]y_V=f(x_V)=2\cdot3^2-12\cdot3+19=2\cdot9-36+19=1[/tex]Hence we say that the final answer is
Vertex is a minimum point at (3, 1)

The function f(x) grows at the same rate as the function g(x) according to the condition : [tex]\lim_{x \to \infty} \frac{f(x)}{g(x)} =1000[/tex].
We are given two functions. The functions are f(x) and g(x). The definitions of the functions are not given explicitly, but we need to find the relationship between the functions. Both functions grow at a certain rate. We need to find the condition that shows that the function f(x) grows at the same rate as the function g(x). The ratio of the limiting values of the two functions must be a finite and non-zero constant for the functions to have the same rate of growth.

The options that can help prove that the triangles EFG and JHG are congruent are determined as follows:
Two triangles are said to be congruent (or the same) if:
i) One of the triangles has the lengths of all its sides equal to the lengths of the sides of the other triangle.
This scenario is called the SSS scenario
ii) One of the triangles has the lengths of two of its sides equal to the lengths of two sides of the other triangle, and then both of the two triangles have an angle in common.
This scenario is called the SAS scenario
From the above explanations, we can tell that the two triangles EFG and JHG will be congruent under the scenarios SAS and SSS

Susanna. If Susanna takes one piece of candy from the bag without looking, what is the
probability the piece she takes will be chocolate?
Answers
The probability the piece Susanna takes will be chocolate 8/19
Juan has a bag of candy with 20 pieces
40% of the pieces are only chocolate
Number of only chocolate pieces = (40/100) 20 = 8 pieces
20% of the pieces are only caramel.
Number of only charamel pieces = (20/100) 20 = 4 pieces
The remainder of the pieces are only toffee
number of toffee = 20 - 8 - 4 = 8
Juan eats 1 piece of caramel candy from the bag
For Sussana
Now the number of caramel pieces are 3
and the number of candies present = 20 - 1 = 19
probability = number of desired outcomes/ sample space
P(chocolate) = 8/19
Therefore the probability the piece Susanna takes will be chocolate 8/19

Josie sold 965 tickets to a local car show for a total of $4,335.00. A ticket for childrencosts $3.00 and an adult ticket costs $5.00. How many of each ticket did she sell?
Answers
Answer:
[tex]\begin{gathered} 245\text{ children tickets were sold.} \\ \text{ 720 adult tickets were sold.} \end{gathered}[/tex]Step-by-step explanation:
To approach this situation, we need to create a system of linear equations.
Let x be the number of children
Let y be the number of adults
For equation 1)
Since the sum of the tickets sold are 965, it means children plus adults is 965
[tex]x+y=965[/tex]For equation 2)
Since the price for children is $3, the adult ticket costs $5, and the total of tickets sold is $4,335:
[tex]3x+5y=4335[/tex]Now, we can solve this by using the substitution method, isolating one of the variables in equation 1 and plugging it into equation 2.
[tex]y=965-x[/tex]Plug it into equation 2:
[tex]3x+5(965-x)=4335[/tex]Solve for x.
[tex]\begin{gathered} 3x+4825-5x=4335 \\ 5x-3x=4825-4335 \\ 2x=490 \\ x=\frac{490}{2} \\ x=245 \\ 245\text{ children tickets were sold.} \end{gathered}[/tex]Knowing the value for x, we can plug it into equation 1, and solve for y.

can you show me step by step how to divide 6 1/8 divided by 1 3/4
Answers
From the question we are asked to divide 6 1/8 by 1 3/4
To do this, we first convert this improper fraction to proper fraction
6 1/8 = 49/8
1 3/4 = 7/4
The next step is to convert to decimal.
49/8 = 6.125
7/4 = 1.75
So lets divide 6.125 by 1.75
6.125/1.75 = 3.5
Now let's convert the decimal back to fraction
3.5 in fraction = 7/2 = 3 1/2
So, 6 1/8 divide by 1 3/4 = 3 1/2

use the figure two parallel lines cut by a transvesal.
Answers
Answer:
a. 137°
Explanation:
∠1 and ∠8 are corresponding angles. They are in the same relative position with respect to the parallel lines and the transversal.
Then, corresponding angles have the same measure, so:
∠8 = ∠1
∠8 = 43°
Now, ∠8 and ∠6 form a straight line, so the sum of these angles is 180°. Therefore, the measure of ∠6 can be calculated as:
∠6 = 180 - ∠8
∠6 = 180 - 43
∠6 = 137°
So, the answer is a. 137°

Let one of the angles is x

The third angle is 45 more than the smallest angles
So, the angles are x , 3x and (x + 45)
We should know that the sum of the angles of the triangle = 180
so,
x + 3x + (x + 45) = 180
Solve to find x
So,
x + 3x + x + 45 = 180
5x = 180 - 45
5x = 135
Divide both sides by 5
x = 135/5 = 27
So, the angles are 27 , 81 and 72
so, the smallest angle = 27
The middle angle = 72
The largest angle = 81
