Solve the quadratic using the quadratic formula. *
Solve:
6x^2 + 7x – 5 = 0

Answers

Answer 1

Answer:x = -5/3 or x = 1/2

Step-by-step explanation:

Let's solve your equation step-by-step.

6x2+7x−5=0

Step 1: Factor left side of equation.

(3x+5)(2x−1)=0

Step 2: Set factors equal to 0.

3x+5 = 0 or 2x−1 = 0

x = -5/3 or x = 1/2

Answer 2

Answer:

[tex]x=\frac{1}{2}[/tex]

[tex]x=-1\frac{2}{3}[/tex]

Step-by-step explanation:

[tex]x=\frac{-b±\sqrt{b^{2} +4ac} }{2a}[/tex]

Ignore the A before the ±, it wouldn't let me type it correctly.

6x² + 7x - 5 = 0

a = 6

b = 7

c = - 7

[tex]x=\frac{-(7)±\sqrt{7^{2} +4((6)(-5))} }{2(6)}[/tex]

[tex]x=\frac{-(7)±\sqrt{49 +4((6)(-5))} }{2(6)}[/tex]

[tex]x=\frac{-(7)±\sqrt{49 +120} }{2(6)}[/tex]

[tex]x=\frac{-7±\sqrt{169} }{12}[/tex]

[tex]x=\frac{-7±13 }{12}[/tex]

Two separate equations

[tex]x=\frac{-7+13 }{12}[/tex]

[tex]x=\frac{-7-13 }{12}[/tex]

________________________

[tex]x=\frac{-7+13 }{12}[/tex]

[tex]x=\frac{6 }{12}[/tex]

[tex]x=\frac{1}{2}[/tex]

[tex]x=\frac{-7-13 }{12}[/tex]

[tex]x=\frac{-20 }{12}[/tex]

[tex]x=-1\frac{2}{3}[/tex]

Which describes a type of tax that funds city programs? Oprogressive tax federal income tax Olocal income taax Omedicare tax​

Answers

Answer:

local income tax

Explanation:

The "local income tax" refers to the tax levied to people who are residing or working in a specific local area. This is the tax being used to fund the city programs that will help improve the community.

Such programs include the development of parks in the area, including landscape beautification or enhancement of the public markets, improvement of public schools, etc.

Local income tax may appear as a "withholding tax" in some situations. In this case, it is automatically being withheld from the wage of a worker.

Compute the answers for this fish tank containing water.


Compute the mass of water filling this tank.

0.25 g
20 g
250 g

Answers

Answer:

Option (3)

Step-by-step explanation:

Since density on an element = [tex]\frac{\text{Mass}}{\text{Volume}}[/tex]

Volume of the water in the aquarium = volume of the aquarium

                                                              = Length × width × height

                                                              = 10 × 5 × 5

                                                              = 250 cm³

We know density of the water = 1 gram per cm³

By putting these values in the formula,

1 = [tex]\frac{\text{Mass}}{250}[/tex]

Mass = 250 g

Therefore, Option (3) will be the answer.

What is the equation of the graph?​

Answers

Answer:

the contant of proportionality is 2y = 3x

Step-by-step explanation:

1. Match the given equation (y = 2x) to the pattern ...

  y = kx . . . . . k is the constant of proportionality

Hopefully, you can see that k corresponds to 2. That is, the coefficient of x is the constant of proportionality. It is 2.

__

2. Since you're studying proportions, it is useful to look at the ratio of the y-value to the x-value. In each case, it is 6/2 = 9/3 = 15/5 = 3. Then the graph shows the variables are proportional, with a constant of proportionality of 3.

Is the difference between a rational number and an irrational number always an irrational number ?

Answers

Answer: Of course!

Step-by-step explanation: I will suck at explaining this. Here's the general idea: A rational number is a number that is the quotient of two integers, or whole numbers. Rational numbers are things like 2, 5, 6, 2.5, 2.25, 6.53465, 1.666666666666666666666666666667; you get the idea. The point is, it can be represented by the fraction of two integers. An irrational number is something that cannot be represented this way. It's the same thing with multiplying an even number by an odd number; it'll always be odd, regardless of what the odd number is. Same with odd - even; it'll always be odd. Point being, there is no rational number that can be subtracted by an irrational number and be rational, or an irrational number that is subtracted by a rational number.

Write the equation of a line perpendicular to y=3x+5 and passes through the point (1,7).

Answers

Answer:

y = -3x + 10

Step-by-step explanation:

The slope of perpendicular line is the opposite and reciprocal of the original line.

3 -> -3

Find the new y-intercept.

y = -3x + b

7 = -3(1) + b

7 = -3 + b

10 = b

y = -3x + 10

Which graph represents a line with a slope of - į and a y-intercept equal to that of the line y = = x-27
ТУ

Answers

Answer:

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Where m = slope of the line

b = y-intercept

Slope of the line 'm' = -[tex]\frac{2}{3}[/tex]

y-intercept 'b' of the line is equal to the y-intercept of another line given as,

[tex]y=\frac{2}{3}x-2[/tex]

Here y-intercept of the line 'b' = -2

Therefore, the equation of the line will be,

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

[tex]y=-\frac{2}{3}x-2[/tex]

Here negative slope represents a line which is decreasing having y-intercept = -2
