Answer:
d = 10 sqrt(2)
Step-by-step explanation:
The distance formula is
d = sqrt( (y2-y1) ^2 + ( x2-x1)^2)
d = sqrt( (-1-9) ^2 + ( -4-6)^2)
d = sqrt( (-10) ^2 + ( -10)^2)
d = sqrt( 100+100)
d = sqrt(200)
d = sqrt( 200*2)
d = sqrt(100) sqrt(2)
d = 10 sqrt(2)
What is the expression under the radical sign in the quadratic formula called? *
coefficient
degree
discriminant
O conjugate
5 poin
The formula for the discriminant is
d = b^2 - 4ac
If d < 0, then there are no real number solutions
If d = 0, then you have exactly one real solution
If d > 0, then you have two different real number solutions
The furniture store sells each chair (c) for $225. To have them shipped to their house, the store charges $60. If the Browns bought c number of chairs, how much did they spend (s)?
==========================================================
Explanation:
1 chair = 225 dollars
c chairs = 225c dollars .... multiply both sides by c
This shows that buying c chairs costs 225c dollars
c is a placeholder for a positive whole number
Add on the $60 shipping cost to get the total cost 225c+60
Therefore s = 225c+60

Divide both sides by the numeric factor on the left side, then solve.
-2x+1=-x+8
WHAT IS X
Answer:
x=-7
Step-by-step explanation:
add 2x to -x to get 1=x+8, then subtract 8 to get x=-7
Answer:
x = -7
Step-by-step explanation:
1 Regroup terms.
-2x+1=8-x−2x+1=8−x
2 Add 2x2x to both sides.
1=8-x+2x1=8−x+2x
3 Simplify 8-x+2x8−x+2x to 8+x8+x.
1=8+x1=8+x
4 Subtract 88 from both sides.
1-8=x1−8=x
5 Simplify 1-81−8 to -7−7.
-7=x−7=x
6 Switch sides.
-7 = x
x=−7

What is the equation of the line that is parallel to the
given line and passes through the point (-2, 2)?
O y=1/5x+4
Oy= 1/5x+12/5
O y = -5x + 4
O y=-5x +12/5
The equation of the parallel line that passes through the point (-2, 2) is y= (1/5) x + (12/5)
What is meant by line's slope?The slope of a line indicates how steep it is. Slope is defined mathematically as "rise over run." Choose two points on the line and calculate their coordinates. Determine the difference in y-coordinates between these two points. Determine the difference in x-coordinates between these two points. Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).There are four types of slopes: negative, positive, zero, and undefined. as x grows The slope of a line can also be interpreted as the "average rate of change."Therefore,
The slopes of the two lines will be the same because it runs parallel to the line predicted by the equation.
The slope of the line is 1/5,
We know that the line is y= (1/5) x + c.
We can now find the y-intercept using the given point (-2,2).
[tex]$&\Rightarrow y=m x+c \\[/tex]
[tex]&y^2=\frac{1}{5}(-2)+c \\[/tex]
[tex]&\Rightarrow^2=\frac{-2}{5}+c \\[/tex]
[tex]&\Rightarrow c=2+\frac{2}{5}=\frac{10+2}{5}=\frac{12}{5} \\[/tex]
[tex]&\Rightarrow c=\frac{12}{5}[/tex]
Hence, The line's final equation will be [tex]y=\frac{1}{5} x+\frac{12}{5}[/tex]

Answer:
(6, -2)
Step-by-step explanation:
The midpoint of the segment RS is point M (5, 3). Therefore, the average of the x coordinates of R and S is 5, and the average of the y coordinates of R and S is 3. The x coordinate of R is 4. For 4 and the x coordinate of S to have an average of 5, the x coordinate of S must be 6. Therefore, our point is of the form (6, y). For 8 and the y coordinate of S to have an average of 3, the y coordinate of S must be -2. Therefore, our answer is (6, -2)

BOXES Simon will make a box without a top by cutting out corners of equal size from a 22 inch by 15 inch sheet of cardboard and folding up the sides. Which of the following is closest to the greatest possible volume of the box?
a. 330 in3
b. 144 in3
c. 432 in3
d. 1296 in3
Answer:
Volume of box is [tex]432 in^3[/tex]
Step-by-step explanation:
Let x be the side of square corner
Length of box after cutting corners =22-2x
Breadth of box after cutting corners =15-2x
Height =x
Volume of box = (22-2x)(15-2x)x
Volume of box =[tex]4x^3-74x^2+330x[/tex]
Differentiate w.r.t x
[tex]\frac{dV}{dx}=12x^2-148x+330[/tex]
Substitute derivative =0
[tex]12x^2-148x+330=0\\x=\frac{37-\sqrt{379}}{6},\frac{37+\sqrt{379}}{6}\\\frac{d^2V}{dx^2}=24x-148[/tex]
at [tex]x=\frac{37-\sqrt{379}}{6}[/tex]
[tex]\frac{d^2V}{dx^2}=24x-148=24(\frac{37-\sqrt{379}}{6} )-148=-77.87 < 0[/tex] hence maximum
at [tex]x=\frac{37+\sqrt{379}}{6}[/tex]
[tex]\frac{d^2V}{dx^2}=24x-148=24(\frac{37+\sqrt{379}}{6} )-148=77.87>0[/tex] hence minimum
So,Volume of box =[tex]4x^3-74x^2+330x=4(\frac{37-\sqrt{379}}{6} )^3-74(\frac{37-\sqrt{379}}{6} )^2+330(\frac{37-\sqrt{379}}{6} )=432.23 in^3[/tex]
Hence Volume of box is [tex]432 in^3[/tex]

Answer:
I would love to!
The slope is 3, or 3/1
Step-by-step explanation:
To find the slope, you have to count the rise over run. 3 over 1. The best way to find this, is to go up each unit until you see that the line touches an exact point. Once you find that, go over.
