Create a quadratic equation that would have two real solutions. Then,
explain why it has two real solutions without solving the equation.
Answer:
Thinking graphically, these correspond to the graph of the straight line (a) missing the graph of the parabola entirely, (b) kissing the parabola at one point or (c) cutting across the parabola and coinciding with it at 2 points.
Step-by-step explanation:
Explanation:
Graphically, a quadratic equation is a parabola and a linear equation is a straight line.

HELP I'M SOOOOOO ANGRYYYYY PLEASE HELPPPP
determine the values of X for which g(x) is defined
Answer: Any real number x as long as [tex]x \ne 0[/tex] and [tex]x \ne -\frac{2}{3}[/tex]
In other words, anything but 0 or -2/3 is valid.
========================================================
Explanation:
Set the denominator equal to zero and solve for x
2(3x^2 + 2x) = 0
3x^2 + 2x = 0
x(3x + 2) = 0
x = 0 or 3x+2 = 0 .... zero product property
x = 0 or 3x = -2
x = 0 or x = -2/3
If either x = 0 or x = -2/3, then the denominator 2(3x^2 + 2x) will be zero. But recall that we cannot have zero in the denominator. Dividing by zero is not allowed. The expression is undefined when we divide by zero.
Therefore, we must exclude x = 0 and x = -2/3 from the domain. Any other real number is valid as an x input.
It takes Andre 6 minutes to swim 5 laps. (a). How many laps per minute is that? Include how you arrived at your solution.
Answer:
1.2 minutes
Step-by-step explanation:
So its saying it takes 6 mins to do 5 laps. Thats a little over a min per lap so we now its going to be over 1. The first step is to divide 6/5. Then you get 1.2

A table titled Number of Dogs Adopted has entries 3, 3, 4, 4, 4, 5, 5, 6, 6, 6, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 9. The total is 132.
A shelter kept track of the number of dogs adopted each day for three weeks. Use the table to find the statistical measures.
Mean:
Median:
Mode:
Range:
Answer:
mean- 66
median- 7
mode- 8
range- 6
Step-by-step explanation:
to find the mode you line up all the numbers, add them all together and then divide that number by 2.
to find the median you line up all the numbers then one by one taking turns from left to right you cross of the numbers to find the number in the middle. (think of median as middle)
to find mode you just find the number that is used the most. (mode=most)
to find the range you find the highest number and the lowest number. and subtract the lowest from the highest to find the difference between the 2. in this case its 9-3 so the difference is 6.
Answer:
Hello!!! erz here ^^

ILL GIVE U BRAINLIST PLS HELP
Answer:
A. Right a multiple of 2 and up a multiple of 1.
B. (2, 1)
C. the same
Step-by-step explanation:
A. The original point was (2, 1), so if Larissa moves right a multiple of 2 and up a multiple of 1, she'll stay within the ratio.
B. We already know this is proportional, since it goes through the origin; the line just has to pass through the right point: (2,1)
C. The line will be proportional, so as long x is twice as much as y, Larissa will have the same shade of green paint every time.
James earns $8.15 per hour that he works. Which algebraic equation shows the
amount of money. E, that James earns in n hours?
Answer:
e = $8.15n
Although this doesn't require an explanation, I am always open to solve any confusion.
Side Note: I used variable E assuming that the period before 'E' was supposed to be a comma which means it was a given variable.
Answer:
E= 8.15n
Step-by-step explanation:

A farmer has 28 bushels of apples and can harvest 25 bushels of apples each day. In how many days will he have more than 125 bushels to sell? What inequality represents this situation?
Answer: 4 days, there are already 28 bushels of apples
Step-by-step explanation:
In 4 days because 25 times 4 is 100.
100 + 28 is 128 which is more than 125.
What is the complete factorization of the polynomial below? 3 + 4x2 - X-4
Ella drew 15 hearts, 10 stars, and 25 circles. What is the ratio of stars to all shapes?
Answer:
16
Step-by-step explanation:
Graph the solution of this inequality:
350 > 125 + 150
10 20 30 40 50 60 70 80 90 100 110 120
Drag a point to the numb
Step-by-step explanation:
The given inequality is :
[tex]350\ge 125+15x[/tex] ....(1)
We need to draw graph of this inequality.
Subtract 125 from both sides.
[tex]350-125\ge 125-125+15x\\\\225\ge 15x[/tex]
Dividing 15 to both sides.
[tex]\dfrac{225}{15}\ge \dfrac{15x}{15}\\\\15\ge x[/tex]
Hence, the attached figure shows the graph for this inequality.

A'B'/AB = 5.1/1.7 = 3
B'C'/BC = 7.2/2.4 = 3
A'C'/AC = 7.5/2.5 = 3
These ratios are equal to the scale factor. These ratios are the scale factor.
What is the slope of the line that passes through the points (4,5) and (12,7)?
Answer:
(2,8)
Step-by-step explanation:
If we plot both points on the graph and start at (4,5) we count up (rise) 2 and to the right (run) 8. This means they are both positive numbers as it goes up and to the right.
*Down or to the left would be negative.
In a recent survey, 60% of dads prefer to watch football on TV. 40% prefer to watch basketball. If 200 dads were surveyed, how many more preferred football to basketball?
Given :
60% of dads prefer to watch football on TV.
40% prefer to watch basketball.
To Find :
If 200 dads were surveyed, how many more preferred football to basketball.
Solution :
Number of dad prefer football over basketball is :
[tex]N = 200\times \dfrac{60}{100}\\\\N = 120[/tex]
Therefore, 120 dad's prefer football over basketball.

6x + 8
Find the measure of angle 1.
Answer:
44°
Step-by-step explanation:
8x-4 = 6x+8
8x - 6x = 8 + 4
2x = 12
x = 12/2
x = 6
then:
8*6 - 4 = 48 - 4 = 44°
The measure of angle 1:
44°
Triangles triangle ABC and triangle DEF are similar. Find the angles of these triangles if Mesurements of angle A=100 degrees, and mesurments of angle B=30 degrees.
Answer:
<D = 100
<E =30
<F =50
Step-by-step explanation
Given that triangles triangle ABC and triangle DEF are similar, this means that their angles are congruent i.e
<A = <D
<B = <E
<C = <F
Given
<A = 100 then <D = 100
<B = 30°, then <E = 30°
To get <F, we will use the expression
<D+<E+<F = 180 (sum of angles in a triangle is 180°)
100+30+<F = 180
130+<F = 180
<F = 180-130
<F = 50°
Hence the measure of <F is 50°
f(1)=2
f(n+1) = f(n)+4
What is f(10)?
9514 1404 393
Answer:
38
Step-by-step explanation:
The recursion relation describes an arithmetic sequence with a first term of 2 and a common difference of 4. The explicit formula for the n-th term of the sequence is ...
f(n) = f(1) +d(n -1) . . . . . for first term f(1) and difference d
f(n) = 2 +4(n -1) = 4n -2
Then the 10th term is ...
f(10) = 4(10) -2
f(10) = 38

The solution to -45 = n/5 is _____.
-9
9
225
-225
Answer:
the answer is -225
you have to undo the operation that is being done to x. since it's dividing, you have to multiply both sides by 5 to "undo" what had been done. 5*-45= -225
