Answer:

[tex]y=(x+1)^2-1[/tex]

which agrees with the last option listed.

Step-by-step explanation:

We use the vertex form of a parabola:

[tex]y-y_v=a(x-x_v)^2[/tex]

which with the information we have becomes:

[tex]y-y_v=a(x-x_v)^2\\y-(-1)_v=a(x-(-1))^2\\y=a(x+1)^2-1[/tex]

Therefore the equation that corresponds to such vertex (-1, -1) is the last one listed among your given answer options.

[tex]y=(x+1)^2-1[/tex]

Step-by-step explanation:

Answer:

x = -3

Step-by-step explanation:

4x - 8 = -4 (11 + 2x) (distribute the -4 to the numbers in the parenthesis)

4x - 8 = -44 + -8x (add 8x on both sides)

12x - 8 = -44 (add 8 on both sides)

12x = -36 (divide both sides by 12)

x = -3

Answer:

c  

Step-by-step explanation:  

There a is parallel to d because a is perpendicular to c and c is parallel to d which is the correct answer that would be option (C).

A group of points that are coplanar, or a planar surface that extends endlessly in all directions, are all located on the same plane. Four or more points may or may not be coplanar, however, any two or three points are always coplanar.

The distinct lines​ a, b,​ c, and d are in the same plane.

a⊥b, bllc, and clld

Line a is perpendicular to line b, line b is parallel to line c, and Line c is parallel to line d which is given in the question.

Line a is perpendicular to line b (given)

Line b is parallel to line c (given)

Line c is parallel to line d (given)

Thus, Line a is parallel to line d

Therefore, a is parallel to d because a is perpendicular to c and c is parallel to d.

Hence, the correct answer would be an option (C).

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Total number of members in the relay team = 3 members

Total distance covered by the 3 members of the relay team = 3/8 miles

Now the equation will be ,

The distance ran by each member of the team =
Total distance covered by the 3 members of the relay team / Total number of members in the relay team

So , The distance ran by each member of the team = ( 3/8 ) / 3

                                                                                     = 3/8 x 1/3

                                                                                     = 1/8 miles

Therefore ,  the distance ran by each member of the team is 1/8 miles

And , taking the sum of each person's distance , we get

1/8 + 1/8 + 1/8 = 3/8

which is the total distance covered by the 3 members

Hence , The distance ran by each person in the relay team is 1/8 miles

Step-by-step explanation:

Answer:

Either, (9+√69)/6 or (9-√69)/6

Step wise:

3x²-9x+1=0-------------------(i)

comparing equation onw with (ax²+bx+c=0), we get,

a=3, b=-9, c=1

now,

using Quadratic Formula,

(-b±√b²-4ac)/2a=x

{-(-9)±√(-9)²-4.3.1}/2.3=x

(9±√81-12)/6=x

(9±√69)/6=x

Taking +(ve) sign                   Taking -(ve) sign

(9+√69)/6=0                           (9-√69)/6=0

∴(9+√69)/6=0                         ∴(9-√69)/6=0

[∵They cannot be further solved]

The solutions to the given quadratic equation are x = 2.884 and

x = 0.116.

The equation of the form ax² + bx +c is known as a quadratic equation.

The given equation is 3x² - 9x + 1 =0.

Solve the equation as follows:

3x² - 9x + 1 =0

Use the quadratic formula to solve the equation:

[tex]x = \frac{-(-9)\pm\sqrt{(-9)^2-4(3)(1)}}{2(3)}\\\\x= \frac{9\pm\sqrt{81-12}}{6}\\\\x=\frac{9\pm\sqrt{69}}{6}\\\\x = \frac{9\pm8.306}{6}\\\\x=\frac{9+8.306}{6}\quad\text{ or }x=\frac{9-8.306}{6}\\\\x=2.884\quad\text{ or }x=0.116[/tex]

Answer:

C. 4 + (x*4)

Step-by-step explanation:

The third expression does not belong with the other three.

This is because instead of multiplying the coefficient outside of the parentheses it adds, unlike the other three. As well as this instead of adding or subtracting in the parentheses it multiplies. It differs from the other three in those aspects.

Step-by-step explanation:

6x° = (2x + 3)° + 77° (Exterior angle of a triangle = sum of two interior angle )

6x = 2x + 3 +77

subtract 2x from both sides

6x - 2x = 2x - 2x + 3 + 77

4x = 3 + 77

4x = 80

therefore:

x = 20°

angle PQR = 120°

angle RSQ = 43 i.e [(2 x 20) + 3)]

Given the line

[tex]y=-x+2[/tex]

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

here

m is the slope and b is the intercept

Thus, the slope = -1

We know that the parallel lines have the same. Thus, the slope of the parallel line is: -1

Using point-slope of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = -1 and the point (4, 0)

[tex]y-0 = -1 (x-4)[/tex]

Writing in the slope-intercept form

[tex]y = -x+4[/tex]

Thus, the slope-intercept form of the equation of the line equation parallel to y=-x+ 2 will be:

                                                      8)

Note: Your line is a little bit unclear. But, I am assuming the

ine is: y = -x-1

Given the assumed line

y = -x-1

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

here

m is the slope and b is the intercept

Thus, the slope = m = -1

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = -1

perpendicular slope = – 1/m = -1/-1 = 1

Using point-slope of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = 1 and the point (4, 3)

[tex]y - 3 = 1 (x-4)[/tex]

Writing in the slope-intercept form

y-3 = x-4

y = x-4+3

y = x - 1

Thus, the slope-intercept form of the equation of the line equation perpendicular to y = -x-1 will be:

Answer:

Simplifying

6x + 32 = 180

Reorder the terms:

32 + 6x = 180

Solving

32 + 6x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-32' to each side of the equation.

32 + -32 + 6x = 180 + -32

Combine like terms: 32 + -32 = 0

0 + 6x = 180 + -32

6x = 180 + -32

Combine like terms: 180 + -32 = 148

6x = 148

Divide each side by '6'.

x = 24.66666667

Simplifying

x = 24.66666667

6x + 32> -4

6x > -4 - 32

6x > -36

x > -6
