Explain how to use the discriminant to determine the number and type of roots of a quadratic equation.
QUICK PLS IM BEING TIMED
Answer:The discriminant is the expression b2 - 4ac, which is defined for any quadratic equation ax2 + bx + c = 0. Based upon the sign of the expression, you can determine how many real number solutions the quadratic equation has. If you get a positive number, the quadratic will have two unique solutions.

Camila owns a small textile company that produces shirts. On a particular day, Camila has one worker come into the shop to make shirts. She must pay the worker $14 per hour and also pay $1.25 per shirt for material costs. What would be Camila's total cost if the worker made 16 shirts in 8 hours? What would be Camila's total cost if the worker made ss shirts in hh hours?
Answer:
$132.00
Step-by-step explanation:
14$ x 8 hours = 112$, 1.25$ x 16 = 20. 112 + 20 =132$. hope this helps.
Harold and his friends want to play another game–pick up sticks. Harold is at the store with his father to buy red sticks and blue sticks. The store sells red sticks in packs of 8 and blue sticks in packs of 12. To play the game, Harold needs an equal number of red sticks and blue sticks. Harold wants to buy the minimum number of packs that will give him an equal number of red and blue sticks without any sticks of either color leftover. What is the LCM of 8 and 12?
Answer:
He is going need to buy 2 packs of blue sticks and 3 packs of red packs

Q1: why are some of the line segments steeper than others?
Answer:
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. ... A slope with a greater absolute value indicates a steeper line. The direction of a line is either increasing, decreasing, horizontal or vertical.
Step-by-step explanation:
here are a few more things you might want to know will douing this
How do you know which slope is steeper?
When you look at the two lines, you can see that the blue line is steeper than the red line. It makes sense the value of the slope of the blue line, 4, is greater than the value of the slope of the red line, . The greater the slope, the steeper the line.
Can you create a line segment with infinite steepness?
An infinite slope is simply a vertical line. When you plot it on a line graph, an infinite slope is any line which runs parallel to the y-axis. You can also describe this as any line that doesn't move along the x-axis but stays fixed at one constant x-axis coordinate, making the change along the x-axis 0.
How does rate of change affect the steepness of a line?
The steepness of a line is essentially the slope. ... A negative slope would be depicted by a line going from the upper left to bottom right. Slope values increase the higher the number is: For instance, a line with a slope of 2 is steeper than a line with a slope of 12 . Hope this helps!Jun 20, 2018
What are the 3 slope formulas?
There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form.
What is a 6% grade?
A road sign indicating a 6% grade, or 6% slope. A six percent slope means that the road elevation changes 6 feet for every 100 feet of horizontal distance (Figure 1.3). ... A road climbs at a gradient of 6 percent. The road gains 6 feet in elevation for every 100 feet of horizontal distance.
What does the slope represent?
The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x.

How do you find how many solutions a equation has?
Answer:
If solving an equation yields a statement that is true for a single value for the variable, like x = 3, then the equation has one solution. If solving an equation yields a statement that is always true, like 3 = 3, then the equation has infinitely many solutions.
A 12% brine solution was mixed with a 16% brine solution to produce a 15% brine solution. How much of the 12% solution and how much of the 16% solution were used to produce 40 L of the 15% solution?
Answer:
10 liters
Step-by-step explanation:
x=12% solution, y=16% solution
x+y=40
0.12x+0.16y=6 . (12x+16x=600)
-12x-12y=-480
12x+16x=600
+ -12x-12y=-480
-------------------------------
4x=120
x=30
12% solution= 30 liters
16% solution= 10 liters
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
10L of the 12% of solutions and 30L of the 16% of solutions were used to produce 40L of the 15% of solutions.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
Let 12% brine solution be x.
Let 16% brine solutions be y.
12% brine solution was mixed with a 16% brine solution to produce 40L of the 15% solution.
This can be written as,
x + y = 40 ______(1)
0.12x + 0.16y = 0.15 x 40
0.12x + 0.16y = 6 _______(2)
We will solve for x and y.
From (1) we get,
x + y = 40
x = 40 - y _____(3)
Putting ( 3) in (2)
0.12 (40 - y) + 0.16y = 6
4.8 - 0.12y + 0.16y = 6
4.8 + 0.04y = 6
0.04y = 6 - 4.8
0.04y = 1.2
y = 1.2/0.04
y = 30
Putting in (3) we get,
x = 40 - 30 = 10
Thus,
10L of the 12% of solutions and 30L of the 16% of solutions were used to produce 40L of the 15% of solutions.

Shane and Abha earned a team badge that required their team to collect no less than 2000 cans for recycling. Abha collected 178more cans than Shane did.
Answer:
Shane collected 911 cans.
Step-by-step explanation:
S - represents Shane
S + (S + 178) ≥ 2000
2S + 178 ≥ 2000
*subtract 178 from both sides*
2S ≥ 1822
*divide both sides by 2*
S ≥ 911

Answer:
x is a variable
Step-by-step explanation:
what happens an squared plus B equals C and what I want to do is solve for a so again what we want to do is when we're taking solver a we want to isolate the variable get the variable by itself so the data that need to look at well what is happening on my variable a well you can see me as being multiplied by X and it's being added by B so I need to undo those but we got to make sure we undo them in a certain upper certain order which we call the reverse order of operations which is like the order of operations but the reverse method meaning I'm gonna undo addition or subtraction first so you can see that since my variable a is being added by B I need to undo that by subtracting B and I'll use my subtraction property of equality that's going to now subtract a 0 and then these C minus B are not like terms so I'm going to write ax is equal to C minus B now I need to solve for a so I need to look at and say alright my a is being x over X so the inverse operation of multiplying is dividing by X so therefore have a equals C minus B divided by X now sometimes you could say alright that's correct but we could also divide this X into both of these terms and I'm going to rewrite this in a different form I could say a equals C over X minus B over X alright so what I'm doing is are just dividing those through

The difference of 2 integers is 6. The sum of the same 2
integers is 42. What is the lesser of the 2 integers?
Step-by-step explanation:
x - y = 6
x + y = 42
substitute
x = y + 6
( y + 6) + y = 42
2y + 6 = 42
2y = 36
y = 18
x = y + 6
x = 18 + 6
x = 24

< is angle
For the first one, <2+<3 equals 180
So, 37+<3=180. Rewrite that, and <3=180-37, which then <3 is 143 degrees
For the second one, COMPLEMENTARY ANGLES ADD UP TO 90 DEGREES
So, if one angle is 35 degrees, and we rewrite that again, 90-35 is it's complement.
So the answer to the second one is 90-35, 55.
