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
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]

Let me know if you want the answer, but what you need to do first is get the opposite angles.
They're on straight lines, so 180 minus that angle would equal the angle inside the triangle.
Then all inner angles if a triangle add up to 180° so 180 minus the two other angle would give you the final missing angle.
Do the straight line thing again and subtract 156 from it.

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]
A pair of parallel lines is cut by a transversal: A pair of parallel lines is cut by a transversal. The interior angle made on the left by the intersection of the upper parallel line and the transversal is divided into 2 parts by a slanting line. One part of this angle is labeled as x, and the other part is labeled as 30 degrees. The interior angle made on the right by the intersection of the lower parallel line and the transversal is labeled as 75 degrees. What is the measure of angle x? (1 point)
Answer:
Step-by-step explanation:
Use the diagram in the attachment for reference. You can substitute the values given in question in place of the one in the diagram.
From the diagram, it can be seen that the sum of angle x and 20 is equal to angle 75 degrees i.e x+30 = 75 (alternate angles)
Next is to find the value of x from the equation
x+30 = 75
Subtract 30 from both sides of the equation;
x+30-30 = 75-30
x = 75-30
x = 45
Hence the measure of angle x is 45°
Answer:
The answer is 45

20% of 15 is 3.
(To check 3 x 5 = 15. 20 x 5 = 1.00)
3 +15 = 18.
Answer:
20% is the answer
Step-by-step explanation:
18-15=3 inches
3/15=20%

Solve for the indicated variable x/9 - g = a for x
Answer:
x = 9(a+g)
Step-by-step explanation:
x/9 - g = a
Add g to each side
x/9 - g+g = a+g
x/9 = a+g
Multiply each side by 9
x/9 * 9 = 9(a+g)
x = 9(a+g)

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

Ruth wants to buy a skateboard for $56. She has $90 in her account. She spent $11.65 to buy stationary. She also wants to buy some comic books for $3.72 each. What is the maximum number of comic books, n, that Ruth can buy so that she has enough money left to buy the skateboard?
n ≥ 6
n ≤ 6
n ≤ 16
n ≥ 16
Answer:
n ≤ 6
Step-by-step explanation:
She can't buy more than 6 comic books in order to have enough money to buy skateboard.
90 - 11.65 - 56 = 22.35
