Answer:

b

Step-by-step explanation:

By using the substitution method the solution to the given equation is

x = ±7/2 + √5/2

Given the equation expressed as:

(2x +3)^2 + 8(2x + 3) + 11 = 0

Expand the equation

4x^2 + 12x + 9 + 16x + 24 + 11 = 0
4x^2 + 28x + 44 = 0
x^2 + 7x + 11 = 0

Factorize the result to have:

On factorizing the values of x are

x = ±7/2 + √5/2

Step-by-step explanation:

If the triangle is right, then the square of the longest side must equal the sum of the squares on the other 2 sides.

longest side = 12 ⇒ 12² = 144

7² + 7² = 49 + 49 = 98

Since 144 ≠ 98 then triangle is not right

Answers:

Domain:  [tex]x \ge -5[/tex]

Range:  [tex]y \ge -2[/tex]

========================================

Explanation:

The domain is the set of all allowed x values of a function. The point on the very left shows that x = -5 is the smallest value possible. So this means the domain consists of x values such that x = -5 or x > -5. We shorten that to [tex]x \ge -5[/tex]

------------------

The range is the set of possible y outputs. The lowest point is when y = -2 meaning that [tex]y \ge -2[/tex] is the range (so y can be -2 or larger).

Answer:19.3

Step-by-step explanation:add all angles of the shape that should give you 733

The minus 733 from 1080 because interior angles in a octagon add to 1080 this should give you 347 the add the the x together giving you 18x then divide 347 by 18 that give 19.27 rounded up to 19.3

.07 miles

explanation

365 days in a year

and 5280 feets in mile

subtract 365 from 5280 which equals 4915 and divide it by 5280 since u want the percent 4915/5280 = 0.0930871212121 and u get .07 after u subtract that number by 100

[tex]\frac{4}{7}[/tex]

Step-by-step explanation:

The y -intercept of the given line is [tex]\frac{4}{7}[/tex];

      y  = x + [tex]\frac{4}{7}[/tex]

 The equation of any line is y = mx + c;

y and x are the coordinates

m is the slope

c is the y-intercept

             y  = x + [tex]\frac{4}{7}[/tex]

So   [tex]\frac{4}{7}[/tex] is the y-intercept

Answer:

+6

Step-by-step explanation:

Just do [tex]0 -(-6)[/tex].

Answer:

B

Step-by-step explanation:

First we find how much of 125000 is increasing. Once we do that, it is basically a slope intercept equation.

We know that 1.6 percent of 125000 is 2000.

We know have y=2000x+125000

There are two ways to solve this, either plug in the given values of a, b, c, and d into the equation and see if it equal 175000, or we we set the equation equal to 175000

If we do the second easiet option, we have

2000x+125000=175000 Use inverse operations

2000x=50000

x=25, or roughly option b.

If we plug in b, we get y=2000(21)+125000 or 167000

21.0 years will it take the population of that city to reach 175,000.

Population growth rate is the change in the number of individuals over a specific period of time. Population growth rate can be interpreted over any time period.

Given

Population of a city is growing at an uninhibited rate of 1.6% per year.

The city's initial population was 125,000.

Based on the given conditions

[tex]125000.(1+0.016)^{x} =175000[/tex]

⇒ [tex]125000.(1.016)^{x} =175000[/tex]

⇒ [tex](1.016)^{x} =\frac{175000}{125000}[/tex]

⇒ [tex](1.016)^{x} =\frac{7}{5}[/tex]

⇒ [tex]x=log_{1.016} \frac{7}{5}[/tex]

⇒ [tex]x=log_{\frac{127}{125} } \frac{7}{5}[/tex]

⇒ x = 21.0

21.0 years will it take the population of that city to reach 175,000.
