What are the values of a, b, and c in the quadratic equation –2x^2 + 4x – 3 = 0?
Answer:
a.-2
b.4
c.-3
Step-by-step explanation:
write a,b,c on top of each number to the left of the =0
Answer:
The values are: a ; (-2) b ; (4) c ; (-3)
Step-by-step explanation:
The quadratic equation is: ax^2+bx+c = 0
So, you can get your answers by using that.
Match each quadratic function with its respective graph.
f (x) = x^2 + 6x - 5
f (x) = x^2 - 4x + 5
f (x) = -x^2 - 2x +3
f (x) = x^2 + 4x - 5
f (x) = -x^2 + 2x - 3
f (x) = x^2 - 6x + 5
The quadratic functions that fits with its respective graph are.
1). f (x) = x^2 - 4x + 5
2). f (x) = -x^2 - 2x +3
3). f (x) = x^2 - 6x + 5
Here is how it looks.
The graph has been plotted to show the graphs that corresponds to the equations.
What is a Quadratic Equation?A quadratic equation is what can be written in the form of ax²+bx+c=0
The equations given are
f (x) = x² + 6x - 5
f (x) = x² - 4x + 5
f (x) = -x² - 2x +3
f (x) = x² + 4x - 5
f (x) = -x² + 2x - 3
f (x) = x² - 6x + 5
The quadratic equations are plotted to determine which graph is corresponding to which equation.

Solve the equation. –3|y – 3| = 9
Answer:
y = 0
Step-by-step explanation:
-3(y-3)=9
One solution was found :
y = 0
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-3*(y-3)-(9)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(0 - 3 • (y - 3)) - 9 = 0
Step 2 :
Equation at the end of step 2 :
-3y = 0
Step 3 :
Solving a Single Variable Equation :
3.1 Solve : -3y = 0
Multiply both sides of the equation by (-1) : 3y = 0
Divide both sides of the equation by 3:
y = 0
Answer:
No solution
Step-by-step explanation:
–3|y – 3| = 9
⇌ (Divide both sides by -3)
|y – 3| = -3 impossible
because |y – 3| is greater than 0 and -3 is less than 0.

Answer:
26.25 in³, y = 15x
Step-by-step explanation:
2. Volume is multiplying the length, width, and height of a rectangular prism together.
Therefore, the volume of this rectangular prism is 6 * 1.25 * 3.5
= 26.25 in³
3. The equation that represents the function table will describe the relationship between x and y. As we can see, for every x value, the y value grows by 15. Therefore:
y = 15x

The next fraction in the sequence is:
4/27Step-by-step explanation:
How you can see, the fractions are decreasing as the sequence advance, to identify the proportion in which it decreases, we will divide the first and the second fractions:
3/4 / 1/2 = 3/2 or 1.5Now, we just need to divide all the fractions in 3/2 to identify the next fraction, as I show below:
3/4 / 3/2 = 1/2 1/2 / 3/2 = 1/3 1/3 / 3/2 = 2/9 2/9 / 3/2 = 4/27As you can see, all the results own to the sequence given, for this reason, the last result 4/27 is the correct fraction next to 2/9.

What is the area of the shaded part of the diagram? (Use 3.14 as an estimate for 1.)
Answer:
A
Step-by-step explanation:
first lets find the area of the square
A=l*w
12*12=144 m^2
then lets find the are of the circle
A=pi*r^2
A=3.14*(d/2)^2
the diameter of the circle is 12m
A=3.14*(12/2)^2
A=3.14*(6)^2
A=3.14*36
A=113.04 m^2
Now, lets subtract the area of the circle form the area of the square
144-113.04= 30.96 m^2
So, the answer is A

perimeter
Answer:
62 cm
Step-by-step explanation:
48/4 = 12 so 1 side = 12
the base of the triangle therefore must also be 12 so 38 - 12 = 26
26 + 36 = 62
(2 sides of triangle + 3 sides of square)
if f(x)=x^2 and g(x)=1/2x+3 find g(f(-1))
Answer:

Step-by-step explanation:
F(x)=x^2
g(x)=1/(2x+3)
g(f(-1))=?
x=-1→f(-1)=(-1)^2→f(-1)=1
g(f(-1))=g(1)=1/[2(1)+3]=1/(2+3)→g(f(-1))=1/5

Write an equation in slope-intercept form for the line.
slope = 0, y-intercept = 3
Answer: y = 0x+3 or y = 3
The slope is 0 and the y intercept is 3. So m = 0 and b = 3.
Plug those into y = mx+b to get y = 0x+3, and that simplifies to y = 3.
This graphs out a horizontal line that passes through the two points (0,3) and (1,3).

Answer:
4. 30m; the coefficient is 30.
Step-by-step explanation:
According to wiki, a coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression; it is usually a number. For example, 4x +7 has a coefficient of 4 and a variable of 'x'. The product of 6 and 5 is thirty and the product of 30 and 'm' is 30m.
The temperature in degrees Celsius, c, can be converted to degrees Fahrenheit, f, using the equation f = StartFraction 9 Over 5 EndFraction c + 32. Which statement best describes the relation (c, f)?
A. It is a function because –40°C is paired with –40°F.
B. It is a function because every Celsius temperature is associated with only one
Fahrenheit temperature.
C. It is not a function because 0°C is not paired with 0°F.
D. It is not a function because some Celsius temperatures cannot be associated with
a Fahrenheit temperature.
Answer:
B
Step-by-step explanation:
This is the answer because a function cannot have an x-value that produces more than one y-value.
The equation is in slope-intercept form (y = mx + b), where F is y and C is x.
Bill receives a monthly stipend of $800. He also works at a bookstore making $8 an hour. He wants a monthly income of $1,200. How many hours does he need to work each month?
Answer:
150 hours
Step-by-step explanation:
Bill receives $800 as monthly stipend. But after this statement, it says Bill also works at a bookstore. So, it should mean that Bill does not receive $800 from the bookstore. He receives $800 from another job because of the word "also" which is mentioned in the second statement.
If the question is, to find out the number of hours Bill has to work each month if he assumes his monthly income to be $1,200 then 1200/8 = 150
But if the question is trying to mean that Bill receives $800 as a monthly stipend from the bookstore then this answer is wrong.
Then, we would have to calculate the difference.
$1200 - $800 = $420
Time = $420/8 = 50 hours.
Everything depends on the question. The question however needs some explanation, because this question is not written in a clear way.

Answer:
x=4
Step-by-step explanation:
split the triangle into two and you will get another smaller triangle as shown in what I have drawn
so notice that there's a right angle?? this means that this is a right angle triangle and you can use Pythagoras theorem to solve it
so by Pythagoras theorem, 5^2= 3^2 + x^2
then you can solve for x
