Which of the following is the discriminant of the quadratic equation 2x² 6x 3 0?

Answer:

x= 136 degree ( being vertically opposite angle)

Answer:

x = 136

Step-by-step explanation:

x and 136 are vertical angles and congruent, then

x = 136

Answer:

-3

Step-by-step explanation:

-9 divided by +3 can be written as -9 divided by 3, because when you have a positive number, you don't have to write a plus sign in front of it. Next, we can just do 9/3 and then add the negative sign to the result to get our answer. 9 divided by 3 is equal to 3, and when you add the negative sign, you get -3.

Answer (assuming the question allows it to be written in slope-intercept form):

[tex]y = -\frac{3}{5} x-\frac{9}{5}[/tex]

Step-by-step explanation:

1) First, find the slope of the equation. Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], substitute the given points' x and y values, and simplify:

[tex]m = \frac{(-3)-(0)}{(2)-(-3)} \\m =\frac{-3-0}{2+3}\\m = -\frac{3}{5}[/tex]

Thus, the slope is [tex]-\frac{3}{5}[/tex].

2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] and substitute real values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex].

Since [tex]m[/tex] represents the slope, substitute [tex]-\frac{3}{5}[/tex] in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line crosses, use the x and y values of any one of the given points to substitute into the formula. (Either one is fine. I chose (2,-3).) Then, isolate y to put it into slope-intercept form and find the answer:

[tex]y-(-3) = -\frac{3}{5} (x-(2))\\y + 3 = -\frac{3}{5} x + \frac{6}{5} \\y = -\frac{3}{5} x - \frac{9}{5}[/tex]

[tex]1.10 \times 4 = 4.40[/tex]

[tex]70.40 - 4.40 = 66[/tex]

[tex]66 \div 4 = 16.5[/tex]

Each CD was $16.50 before tax

Proof

[tex]total \: cost = 16.5(4) + 1.10(4)[/tex]

[tex]total \: cost = 66 + 4.40[/tex]

[tex]total \: cost = 70.40[/tex]

Answer:

3 - Perpendicular.

4 - Parallel.

Step-by-step explanation:

[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

[tex]JK = \frac{1-(-7)}{-4-(-10)} = \frac{8}{6} = \frac{4}{3}[/tex]

[tex]LM = \frac{-2-2}{-6-(-3)} = \frac{-4}{3}[/tex]

Perpendicular, because two lines are considered perpendicular if their slopes are opposite reciprocals.

[tex]JK = \frac{-2-(-2)}{3-11} = \frac{0}{-8} = 0[/tex]

[tex]LM = \frac{-2-(-7)}{1-1} = \frac{5}{0} = 0[/tex]

Answer:

y = 4

Step-by-step explanation:

KM / 10 = KO / 16

(4y - 1) / 10 = 6y / 16

KO = 4y-1 + 2y+1 = 6y

cross-multiply:

60y = 64y - 16

-4y = -16

y = 4

Answer:

4/3

Step-by-step explanation:

Line equations are of the format:

y = m*x + b

((m is slope; b is y-intercept))

So this line has a slope of 4/3 and a y-intercept of -2/3.

4. 4/7 x 1/2 = 4x1/7x2 = 4/14 = 2/7

6. 4/9 x 2/3 = 4x2/9x3=8/27

Answer:

Hey again

2.-  *in order* 3, 9, 15/36, 5/12

4.- *rewrite it in the same order it was in* so, 4/7 x 1/2= 5/14 simplified to=haha jk thats as simplified as it gets/ its 5/14

6.- *rewrite it as is* 4/9 x 2/3 =8/27

Step-by-step explanation:

15/36 simplified *wich you are required to have simplified* is 5/12

Answer:

as we can see here point {\color{Red}a} lies on the interval (-2, -1)

so option A is correct

Step-by-step explanation:

The required minima on the graph in the interval x = -1 and x = -2 is A. Option 4) is correct.

Given that,
A Curve is shown on the graph,
In the interval of x = -1 and x = -2, relative minima is to be determined.

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Since,
A minimum of the curve it that point where the slope of the curve is zero and at that point where the slope is zero the neighboring values must be greater to the point on the curve.

So point a is required minima where the slope is zero and also neighboring values are greater than a

Thus, the required minima on the graph in the interval x = -1 and x = -2 is A. Option 4) is correct.

x≈ 8.3

Step-by-step explanation:

ok first you have to find the hypotenuse of the smaller triangle

a²+b²=c²

2²+4²=c²

4+16=20

√20≈ 4.5

4.5²+7²=c²

20.25+49≈ 69.25

√69.25≈ 8.3

Answer:

x = [tex]\sqrt{69}[/tex]

Step-by-step explanation:

Pythagorean theorem: A^2 + B^2 = C^2

first, find the length of the line cutting through the shape:

let's call this line L.

plug the numbers into the theorem.

4^2 + 2^2 = L^2

16 + 4 = L^2

20 = L^2

next, plug 7 and L into the theorem again to find x

L^2 + 7^2 = x^2

20 + 49 = x^2

69 = x ^2

x = [tex]\sqrt{69}[/tex]

Answer:

T = Toby

T=(23+4)/3

Step-by-step explanation:

If Jennifer’s age is 4 less than 3 times Toby’s age then Jennifer’s age by three,

T=(23+4)/3

and 3 times that, so we divide

T=(23+4)/3

Then Toby is 9 years of age, and shouldn’t be driving.
