Answer:

[tex]a=-3[/tex]

Step-by-step explanation:

[tex]-2a-9=6a+15[/tex]

Add 9 to both sides:

[tex]-2a-9+9=6a+15+9[/tex]

[tex]-2a=6a+24[/tex]

Subtract 6a from both sides:

[tex]-2a-6a=6a+24-6a[/tex]

[tex]-8a=24[/tex]

Divide both sides by -8:

[tex]\frac{-8a}{-8}=\frac{24}{-8}[/tex]

[tex]a=-3[/tex]

Answer:

a=-3

Step-by-step explanation:

-2a-9=6a+15

+2a +2a

-9=8a+15

-15 -15

-24=8a

8 8

-3=a

Answer:

[tex]-1.30\ and\ -7.70[/tex] (2 decimal places)

Step-by-step explanation:

Quadratic Formula: [tex]x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

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

[tex]x^2+9x+10=0[/tex]

Plug in values:

[tex]x=\frac{-9\pm \sqrt{9^2-4\cdot \:1\cdot \:10}}{2\cdot \:1}[/tex]

First value of x:

[tex]x=\frac{-9+\sqrt{41}}{2}=-1.30[/tex] (2 decimal places)

Second value of x:

[tex]x=\frac{-9-\sqrt{41}}{2}=-7.70[/tex] (2 decimal places)

Given:

For a function f, [tex]10 = f(-4)[/tex].

To find:

The coordinates of a point on the graph of f.

Solution:

We have,

[tex]10 = f(-4)[/tex]

It means the value of function f is 10 at -4.

On a coordinate plane x-axis represents the input values and y-axis represents the output values of a function. So,

x-coordinate = input value = -4

y-coordinate = output value = 10

Therefore, the required coordinates of a point on the graph of f are (-4,10).

Answer:

6/5

Step-by-step explanation:

[tex](y2 - y1) \div (x2 - x1) [/tex]

[tex](1 - ( - 5)) \div (7 - 2) = \frac{6}{5} [/tex]

The slope of the line that passes through the points (2, -5) and (7, 1) is 1.2.

Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line.

[tex]Slope = \frac{y2-y1}{x2-x1} \\\\= \frac{1-(-5)}{7-2} = \frac{6}{5} = 1.2[/tex]

Answer:

4/13 hours

Step-by-step explanation:

Total pounds of lasagna = 4 1/3 pounds

Total time taken to cook = 1 1/3 hours

How many hours per pound did it take to cook the lasagna?

Hours per pound of lasagna = Total time taken to cook / Total pounds of lasagna

= 1 1/3 hours ÷ 4 1/3 pounds

= 4/3 ÷ 13/3

= 4/3 × 3/13

= 4/13 hours

It will take 4/13 hours to cook each pound of the lasagna

Step-by-step explanation:

(x + 8)(x - 1) = x^2 - x + 8x - 8 = x^2 + 7x - 8.

Answer:

the probability is 1/2

Step-by-step explanation:

there are 10 cards.

1,3,5,7, and 9 are all 5 odd numbers.

there are 5 numbers left.

2,4,6,8, and 10 are 5 even numbers.

half the cards are odd and the other half is even.

the probability is 1/2 or a half

Answer:

You did not give the options, so i just will graph it.

The inequality is:

-35 - 2*x + 1 < 11.

Now we would want to isolate the x in one side, so we can start by adding 35 in both sides.

(-35 -2*x + 1) + 35 < 11 + 35

-2x + 1 < 46

now we can subtract 1 in both sides:

-2x + 1 - 1 < 46 - 1

-2x < 45

Now we can divide by -2, remember that if we multiply or divide by a negative number, then the "direction" of the sign changes.

(-2x)/-2 > 45/-2

x > -22.5

Then the graph of the set is an open dot at the point x = -22.5 (this means that the set does not include this point) and a line that extends to the right. (Extends to the right because x is larger than -22.5)

Below is an example of how to draw the graph that represents the set of solutions.

Answer: A: (x + 4)² + (y - 5)² = 8

Step-by-step explanation:

The equation of a circle is: (x - h)² + (y - k)² = r²     where

To find the equation of circle A, we need (h, k) and r².

It is given that (h, k) = (-4, 5)

The distance between the center of circles A and B is the radius of circle A.

Let's find the center of circle B by completing the square:

x² - 4x + ____ +  y² + 6y + _____ = 12 + ____ + _____

     ↓                            ↓      

  h = -4/2                    k = 6/2

  h = -2                       k = 3              →  Circle B has center (-2, 3)

Now let's find the distance between the center of circles A and B:

[tex](r_A)^2=d^2=(x_A-x_B)^2+(y_A-y_B)^2[/tex]

                = (-4 - (-2))² + (5 - 3)²

                =     (-2)²     +     2²

                =       4        +     4

                = 8

Now we have the the center (h, k) and the r² for circle A:

(h, k) = (-4, 5) and r² = 8   →    (x + 4)² + (y - 5)² = 8

Step-by-step explanation:

(1)

CD = CE - DE = 8 - 2 = 6

CB = CD = 6 ( given as congruent ) , thus

AC = AB + CB = 4 + 6 = 10

(2)

∠ 2 + ∠ BCD + ∠ DCF  = 180° ( sum of angles on a straight line )

∠ 2 + 60° + 70° = 180°

∠ 2 + 130° = 180° ( subtract 130° from both sides )

∠ 2 = 50°

Answer:

Step-by-step explanation:

the product of odd numbers is always odd

the product of even numbers is always even  

the product of odd number and even one is always even

the sum of two odd numbers is always even

and the sum of two even numbers is always even

so if x is even number we have:

x²=x•x   - even number

x⁴=x²•x²  - even number

3x²=3•x²  - even number

y = x⁴+3x²   - even number

and if x is odd number we have:

x²=x•x   - odd number

x⁴=x²•x²  - odd number

3x²=3•x²  - odd number

y = x⁴+3x²   - even number
