explanation:
I looked it up on Math
way
Answer: x=-2 x=-1/6
Step-by-step explanation: you can use factoring to solve this becuase it is factorable to real numbers. You would want to use quadratic formula is there is an imaginary number or square roots.

In exercises 27-30, three vertices of DEFG are given. Find the coordinates of the remaining vertices: D(-2,-4)
Answers
Answer:
[tex]E =[/tex] [tex](-3,3)[/tex]
Step-by-step explanation:
The question has missing parameters.
The (missing) given coordinates are:
[tex]D(x_1,y_1) = (-2,-4)[/tex]
[tex]F(x_3,y_3) = (0,7)[/tex]
[tex]G(x_3,y_4) = (1,0)[/tex]
Required
Find the coordinates of [tex]E(x_2,y_2)[/tex]
To do this, we make use of mid-point formula which is:
[tex]M = (\frac{x_1+x_3}{2},\frac{y_1+y_3}{2})= (\frac{x_2+x_4}{2},\frac{y_2+y_4}{2})[/tex]
This gives:
[tex](\frac{-2+0}{2},\frac{-4+7}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})[/tex]
[tex](\frac{-2}{2},\frac{3}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})[/tex]
Multiply through by 2
[tex]2 * (\frac{-2}{2},\frac{3}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})*2[/tex]
[tex](-2,3) = (x_2+1,y_2+0)[/tex]
[tex](-2,3) = (x_2+1,y_2)[/tex]
By comparison:
[tex]-2 = x_2 + 1[/tex] and [tex]3= y_2[/tex]
So, we have:
[tex]-2-1=x_2[/tex] and [tex]3= y_2[/tex]
[tex]-3 = x_2[/tex] and [tex]3 = y_2[/tex]
This gives:
[tex]x_2 = -3[/tex] and [tex]y_2 =3[/tex]
Hence, the 4th coordinate is: [tex](-3,3)[/tex]

Step-by-step explanation:
The question is not complete. But I would solve a similar question.
Solution:
A quadrilateral is a polygon shape with four sides and four angles.
Two polygons are said to be similar if they have the same shape and the ratio of their corresponding sides are equal to each other (that is their corresponding sides are in the same proportion).
Given that Quadrilateral ABCD is similar to quadrilateral GHIJ, hence their corresponding sides are similar.

A rental car company charges $31 per day to rent a car and $0.13 for every mile
driven. Jocelyn wants to rent a car, knowing that:
She plans to drive 500 miles.
• She has at most $220 to spend.
.
Write and solve an inequality which can be used to determine d, the number of days
Jocelyn can afford to rent while staying within her budget.
Answers
Answer:
The number of days is at most 5 days
= d ≤ 5 days
Step-by-step explanation:
A rental car company charges $31 per day to rent a car and $0.13 for every mile driven. Jocelyn wants to rent a car, knowing that:
She plans to drive 500 miles.
• She has at most $220 to spend.
At most means Less than or equal to $220
The inequality for expressing this = ≤
Hence, the inequality which can be used to determine d, the number of days Jocelyn can afford to rent while staying within her budget.
$31 × d + $0.13 × 500 miles ≤ $200
The inequality is given as:
31d + 65 ≤ 220
Solving further
31d ≤ 220 -65
31d ≤ 155
d ≤ 155/31
d ≤ 5
Therefore, the number of days is at most 5 days

which line is parallel to one whose equation is y=5x+7
Answers
it can be any number as long as it has that slope :)
ex. y=5x-24
Explanation: Parallel is like being close to something, it's two lines that are going the exact same way but with different y-intercepts, the part of the equation that controls if the line is straight, slanted, etc. is the slope so to be parallel you need the same slope, so the answer is any equation that starts with y=5x.

Answers
Answer:
25
Step-by-step explanation:
Formula
[tex]B = 25(\frac{M}{10} +\frac{3}{4} )[/tex]
Where M meters of granola makes B granola bars.
Given:
M = 2.5 meters
Now substitute that value in the formula and calculate.
[tex]B=25(\frac{2.5}{10} +\frac{3}{4} )= 25(1) = 25[/tex]
Therefore, 2.5 meters of granola makes 25 granola bars.
B = 25

Answer:
(5, 7) is a local maximumFunction is oddStep-by-step explanation:
As we see on the graph:
point (1,2) on the falling section,point (3,3) on the rising section,point (5,7) on the top section,... of the local intervals. therefore only point (5, 7) is a local maximum.
Absolute minimum is - oo, absolute maximum is + oo
A function is even if its graph is symmetric with respect to the y-axis. A function is odd if its graph is symmetric with respect to the origin.The given function is odd as per above definition
