[tex]\\ \rm\bull\rightarrowtail y=1(-6)^2+3(-6)[/tex]

[tex]\\ \rm\bull\rightarrowtail y=1(36)+(-18)[/tex]

Note the rule

[tex]\\ \rm\bull\rightarrowtail y=36-18[/tex]

[tex]\\ \rm\bull\rightarrowtail y=18[/tex]

Answer:

36     -18

18

Step-by-step explanation:

This is slightly confusing, since the question says "find the y coordinate if x = -4" yet underneath if appears they want x = -6 !

If x = -6

Substitute -6 into the equation in place of x

⇒ y = 1 × (-6)² + 3(-6)

Apply the rule (-a)² = a²  and  a(-b) = -ab:

⇒ y = 1 × (6)² + -3×6

⇒ y = 1 × 36 + -18

Using order of operations, carry out the multiplication first:

⇒ y = 36 + -18

Then the addition (subtraction)

⇒ y = 36 - 18

⇒ y = 18

Answer:

  3.6 hours

Step-by-step explanation:

Given that the number of milligrams of a drug in a patient's bloodstream after h hours is D(h) = 25e^(-0.4h), you want to know how much time elapses before the number reaches 6 milligrams.

You want to solve for h the equation ...

  D(h) = 6

  25e^(-0.4h) = 6 . . . . . . use the given expression for D(h)

  e^(-0.4h) = 6/25 . . . . . divide by 25

  -0.4h = ln(6/25) . . . . . take natural logs

  h = ln(6/25)/-0.4 ≈ 3.6

About 3.6 hours is the time needed between injections.

Additional comment

Because there are 6 mg remaining after the first injection when the second is given, it will take about 4.1 hours for the amount to decline to 6 mg after the second injection.

Domain: all real numbers

Step-by-step explanation:

This graph is a parabola. It's equation looks like it should be:

y = x^2 - 1

If you have a graph and are looking for the domain, you are determining where the graph exists. For what x's the graph exists. If you have the equation then the domain is what x's may be put into the equation. There are no limitations on what numbers can go into this equation so the domain is all real numbers.

There are several ways to write the domain is all real numbers, set builder notation and interval notation. But the main idea is that it is all real numbers.

Answer:

-17 or b

Step-by-step explanation:

b = 4(-3) - 5

b = -12 - 5

b = -17

when a = -3 c is -20

- 17 is larger. you may think "oh its 20 that must be larger!" but thats wrong. -17 you be larger because its closer to 0

1/4 The ratio of meters of streamers to cost of streamers is 1 : 0.09

     We want to know the ratio of centimeters of streamers to cost of  
     streamers.

2/4 We need to convert meters to centimeters.

      There are 100 centimeters in 1 meter.

      So, if 1 meter of streamers costs $0.09, then 100 centimeters of
      streamers also cost $0.09.

3/4 The ratio centimeters of streamers to cost for 300 centimeters of
      streamers.

      Now, we can find an equivalent ratio to find the cost for 300
      centimeters of streamers.

4/4 The streamers cost $0.27 per 300 centimeters.

Answer:

6

Step-by-step explanation:

I assume you want the answer as soon as possible so I won't leave an explanation, but comment if you need help or have any questions! :D

Answer:

no, they are not similar

the triangle above is an isosceles triangle, meaning two sides are equal which also means the two angles below are both 55 since one given angle is 55 the other is 55 as well

in the other triangle we are given a different angle, considering this angle is the third unknown angle in the other triangle we will use this to find out if the sum of this angle and the other two 55 degree angles will equal 180 degrees

(sum of interior angles in a triangle is 180)

55 + 55 + 65 = 180?

175 ≠ 180

175 degrees is not equal to 180 degrees so therefore they are not similar.

Answer:

Step-by-step explanation:

a² - b² = (a + b)(a - b)

x² - 16 = x² - 4²

          = (x + 4)(x -4)

8 - 2x =  (-2)*(-4) - 2x

         = -2( -4  + x)

         = -2( x - 4)

6(x² - 16) - (3x +1)(x - 4) + (8 - 2x) = 6(x +4)(x-4)  -(3x +1)(x -4) - 2(x -4)

                   = (x -4) [6*(x+4) - (3x+ 1) - 2]

                   = (x -4) [ 6x + 24 - 3x - 1 - 2]

                    = (x - 4) [ 6x - 3x  + 24 - 1 - 2]

                    = (x - 4)(3x + 21)

                    = (x -4) 3*(x +7)

                    = 3(x -4)(x+7)

The common factors between the two expressions is 1.

A common factor is a number that may be divided by two without leaving a residue. Numbers frequently share more than one aspect in common.

In order to find the common factor between the two expressions, we need to write the terms in factors form. Therefore, both the expression can be written as,

[tex]6ab = 2 \times 3 \times a \times b\times 1[/tex]

[tex]11cd= 11 \times c \times d \times 1[/tex]

As we can see that except for 1, there are no common factors in the two expressions.

Hence, the common factor between the two expressions is 1.

Answer:

Step-by-step explanation: x + 1 = 9x - 3

x + 1 = 9x - 3

(minus x from both sides)

1 = 8x -3

(add 3 to both sides)

4 = 8x

(flip the equation)

8x = 4

(divide both sides by 8)

x = 4/8

x = 1/2 or 0.5
