Answer:
A) -4
Step-by-step explanation:
There are two ways of solving this:
1.) Plugging in the answer choices
Since the equation needs to be equal to or less than 1 (this is due to the less than or equal to sign: ≤)
You will then set the equation: -2x-6 ≤ 1
You will then take each answer choice and plug it into the original equation.
Plug in -4: -2(-4)-6 ≤ 1 this will result in 2 ≤ 1
Plug in -3: -2(-3)-6 ≤ 1 this will result in 0 ≤ 1
Plug in -2: -2(-2)-6 ≤ 1 this will result in -2 ≤ 1
Plug in -1: -2(-1)-6 ≤ 1 this will result in -4≤ 1
The only one that is not true is when you plug in x=-4 into the equation -2x-6. This results in the equation being equal to 2. 2 is not less than 1, making the equation false.
Method 2: Solving the inequality
You can essentially solve for x like a normal inequality.
Instead of solving for -2x-6 = 1, we are doing -2x-6 ≤ 1.
First: Add 6 to the right side
-2x ≤ 1+6 --->>>> 2x ≤ 7
Second: Divid both sides by -2
***Note: When you divivde by a negative when solving an inequality, you must switch the sign. ***
x ≥ -3.5 (hence the sign swtiches from ≤ to ≥ since we divided by a negative value in the equation)
x ≥ -3.5 states that any number greater or equal to -3.5 will work. -4 is less than -3.5, thus it will not satisfy the inequality.

Answer:
(x, y) = (3, 12)
Step-by-step explanation:
Using the given variable definitions, we can write the equations ...
y = x + 9
2(x +y) = 30
__
Solving the second equation for y, we have ...
y = 15 -x
Substituting this into the first equation gives ...
15 -x = x +9
6 = 2x . . . . . . . . . add x-9
3 = x . . . . . . . . . . divide by 2
y = 3+9 = 12 . . . . substitute into the first equation
The numbers are (x, y) = (3, 12).

Step-by-step explanation:
cos²x = 1-sin²x = 1-(5/13)² = 144/169
cosx = √(144/169) = 12/13
tanx = sinx/cosx = (5/13)/(12/13) = (5/13)×(13/12) = 5/12

a. Use the Point-Slope form to find the equation of the line through the points (-5, 2) and (-2, 6).
b. Write the equation from part (a) above into the General as well as the slope-intercept form showing every step.
c. Find the x and y-intercepts of the equation above.
Answers
Answer:
a) y = 4/3x + 26/3
b) 4x - 3y + 26 = 0
c) x-int: (-6 1/2, 0)
y-int: (0, 8 2/3)
Step-by-step explanation:
a) to get points into the point-slope form you first find the slope by taking the difference of the y-values over the difference of the x-values;
slope (m) = (6 - 2) / (-2 - -5) = 4/3
plug 4/3 into 'm' and select one of the two points to plug in their 'x' and 'y' values so you can find 'b' (the y-intercept)
y = mx + b
6 = 4/3(-2) + b
6 = -8/3 + b
b = 6 + 8/3 = 18/3 + 8/3 or 26/3 (or 8.67)
so, put it all together to get the p-s form of y = 4/3x + 26/3
b) general equation is Ax + By + C = 0
take y = 4/3x + 26/3 and multiply each side by 3 to remove denominators
you get: 3y = 4x + 26; rearrange to get 4x - 3y + 26 = 0
c) y-intercept is (0, 8 2/3); derived during step (a)
to get x-intercept, plug zero in for 'y' and solve for 'x':
0 = 4/3x + 26/3
-4/3x = 26/3
cross-multiply and get 12x = -78
x = -78/12 or -39/6 or -6 1/2

A birdwatcher on a cliff saw a eagle 70 feet above him. Earlier, he had spotted the eagle 30 feet above him. Which integer represents the eagle's change in altitude?
Answers
The integer that represents the altitude change is -40
How to determine the integer that represents the altitude change?From the question, the positions of the eagle are
70 feet above him and 30 feet above him
Rewrite the positions of the eagle properly
This is done as follows
Position 1 = 70
Position 3 = 30
The expression of the altitude change in the position of the eagle is then calculated as
Change = Position 2 - Position 1
Substitute the known values in the above equation
So, we have the following equation
Change = 30 - 70
Evaluate
Change = -40
Hence, the altitude change is -40

The probability that more than 30% of the owners in the sample pay for someone to walk their dog is option c. 0.561.
Calculation of the probability:Since 31% of dog owners pay for someone to walk their dogs. Morgan asks a random sample of 50 dog
So
= P> ( 0.30 - 0.31) / √0.31 (1 - 0.31)/ 50
= P(z > - 0.1530)
= 0.5608
= 0.561

Solve the inequality for x. Be sure to show all work to receive full credit.
−3x + 5 ≤ −16
Answers
Answer:
x ≥ 7
Step-by-step explanation:
First, put the same terms on the same side. So subtract 5 from both sides. You will get:
-3x ≤ -21
Divide both sides by -3 to get x alone. When dividing, the inequality sign will change to the opposite. So it will go from a (less than or equal to) sign to a (greater than or equal to) sign.
You will get:
x ≥ 7
Therefore, x will be a number that is greater than or equal to 7.
