Answer:

m = -3 and m = 3

Step-by-step explanation:

[tex] {m}^{2} - 9 = 0 \\ \\ {m}^{2} - {3}^{2} = 0 \\ \\ (m + 3)(m - 3) = 0 \\ \\ m + 3 = 0 \: \: or \: \: m - 3 = 0 \\ \\ m = - 3 \: \: or \: \: m = 3 \\ \\ m = - 3, \: \: 3[/tex]

3rd choice 0.57

Step-by-step explanation:

when rounding to the tenth place we look at the hundreds place and when it greater than or at 5 we round up and when it's less than 5 we round down.

1) explanation:0.7 when rounding to the tenth place. since the 8 was greater than 5 we round-up and get 0.70.

2)explanation: 0.5 when rounded to the tenth place the hundreds place which is 2 is less the 5 so we round down and get 0.50.

3)explanation: 0.6 when rounded its hundreds place is greater than 5 so we round up and get 0.60.

4)explanation: 0.7 when rounding to the tenth place. since the 9 was greater than 5 we round-up and get 0.70.

n=7.5°

Step-by-step explanation:

As the two lines are parallel do the equation is

(10n+19)+(12n-4)=180

10n+19+12n-4=180

22n+15=180

22n=180-15

22n=165

n=165/22

n=15/2

n=7.5

Answer:

y = [tex]\frac{3}{2}[/tex] x - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = [tex]\frac{3}{2}[/tex] , thus

y = [tex]\frac{3}{2}[/tex] x + c ← is the partial equation

To find c substitute (8, 4) into the partial equation

4 = 12 + c ⇒ c = 4 - 12 = - 8

y = [tex]\frac{3}{2}[/tex] x - 8 ← equation of line

The equation of a line that has a slope of 3/2 and passes through (8, 4) can be written as:

[tex]y - 4 = \frac{3}{2} (x - 8)[/tex] (point-slope form) or

[tex]y = \frac{3}{2}x - 8[/tex] (slope-intercept form).

Given:

a point on a line: (8, 4)

slope of the line: 3/2

The equation of the line can be written in either point-slope form or slope-intercept form.

First, let's write the equation in point-slope form since we know one of the points and the slope.

Where,

[tex]y - 4 = \frac{3}{2} (x - 8)[/tex] =>> point-slope form.

[tex]y - 4 = \frac{3}{2} (x - 8)[/tex]

[tex]y - 4 = \frac{3}{2}x - 12[/tex]

[tex]y - 4 + 4 = \frac{3}{2}x - 12 + 4\\\\y = \frac{3}{2}x - 8[/tex](slope-intercept form)

Therefore, the equation of a line that has a slope of 3/2 and passes through (8, 4) can be written as:

[tex]y - 4 = \frac{3}{2} (x - 8)[/tex] (point-slope form) or

[tex]y = \frac{3}{2}x - 8[/tex] (slope-intercept form).

Answer:

You might need to be more specific, it could be 4 puppies to 5 dogs, or 4 apples to 5 oranges or 4 cups of flour to 5 cups of flour.

Step-by-step explanation:

The value of 4:5 is 4 for every 5 like 4 cups of sugar for every 5 cups of flour

The simplified form of ratio 4:5 is 0.8. The ratio is given in the form of p/q.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

It is given that the ratio is 4:5.

To convert mixed numbers into improper fractions, when A is the numerator or B is the denominator,

If either A or B is a decimal number, multiply both of their values by the same factor of 10, which will remove all decimal places.

If one value is a whole number and the other is a fraction, you should try to reduce the fraction to a whole number or convert the whole number to a fraction by giving it a denominator of 1.

= 4 / 5

We have to apply the division operation in which we have to divide the number 4 by 5 in order to obtain the improper fraction values as,

=0.8

Thus, the simplified form of ratio 4:5 is 0.8. The ratio is given in the form of p/q.

As per the quadratic equation, the given equation can be modified into    (x - 2)² = 1. The value of x is 3, 1.

A quadratic equation is an equation where the variable has the highest degree of 2. A quadratic equation might have more than one variable. However, the highest degree of any variable must be 2.

Given equation: x² - 4x + 3 = 0

⇒ x² - 4x + 3 + 1 = 1          (By adding 1 on either side)

⇒ x² - 4x + 4 = 1

⇒ x² - 2 × x × 2 + 2² = 1

⇒ (x - 2)² = 1

⇒ x - 2 = ±1

⇒ x = 3, 1
