Answer:
y-2=1/8(x+5)
Step-by-step explanation:
1. Perpendicular lines have opposite slopes. To get the new slope, take the slope of the first line and turn it to make it the opposite reciprocal.
Since it's -8, the opposite of it is 1/8.
2. Now, use point slope: y-y1=m(x-x1). Plug in the values of the ordered pair and the slope into the equation.
y-2=1/8(x+8)
And that's your answer
Point k lies at (-3,4). Point k is reflected over the y-axis and then translated 7
units down to produce K'. Which rule could have been used to produce K' from K?
K(x, y) +K'(x,y-7)
K(x,y) →K'(-x, y-7)
K(x,y) →K'(x, -y-7)
K(x,y) → K'(-x-7.-y-7)

14) The value of y varies directly with x, and y = 3.6 when x = 6. Find y when x= 48.
Please and thank you. I needed now. Please help
Answer: y = 28.8
Step-by-step explanation:
By using ratios
if the values vary with each other, then they will increase the same amount. 6x8 is 48. So 3.6 x 8 is your answer, 28.8

Answer:
y = 75
z = 43.3
Step-by-step explanation:
To find the value of y we use the trigonometric identity Sine.
[tex]sin\ 30 = \frac{y}{150}\\\\y=150*sin30\\y= 75\\[/tex]
Now to find the value of z we can use the trigonometric identity Tangent.
[tex]tan\ 60=\frac{y}{z}\\\\z=\frac{y}{tan\ 60}[/tex]
We know the value of y is 75 so it becomes,
[tex]z=\frac{75}{1.732} \\\\z=43.3[/tex]
Answer:
y=-150 ' z = - 468
Step-by-step explanation:
Sin angle = opp/hyp
Cos 30 = y/150
y = 150 ×( cos30)
y= - 150
Tan angles = opp / adj
Tan 60 = - 150 / Z
Z = (-150) / tan 60
Z = (-150) / 0.32
Z= - 468
Cooper is opening an online savings account to hold his $20,000 emergency fund. The online account pays 1.5% interest compounded monthly. If Cooper does not deposit or withdraw any money from the account, how much will be in the account in 25 years
Answer:
After 25 years, Cooper will have $29,093.01 in his savings account.
Step-by-step explanation:
While Cooper opened an emergency savings account of $ 20,000, which yields an annual interest of 1.5% compounded monthly, to determine how much money he will have in his account after 25 years, the following calculation must be performed:
X = 20,000 (1 + 0.015 / 12) 25x12
X = 29,093.01
Therefore, after the passage of 25 years, Cooper will have $ 29,093.01 in his savings account.
Mark bought gifts for his friends, and each gift cost $9. Let y represent the total cost and represent the number of gifts. Write an equation to represent the proportional relationship between the total cost and the number of gifts he bought. (4 points) Oy=8x a 1 y = 8 x Oy=9x O 1 y = 9 x
Answer:
y=9x (O 1)
Step-by-step explanation:
9 times the number of gifts he bought which lets say is x will equal your answer (y).

Solve the system, enter ur answer as an ordered triple.
Answer:
x = 1, y = -1, z = 3
Step-by-step explanation:
x - 2y + 2z = 9
y + 2z = 5
z = 3
According to the last equation, z is equal to 3 so we can plug that in and our new 2 equations will be:
x - 2y + 6 = 9
y + 6 = 5
We can subtract 6 from both sides of the second equation to end up with:
y = -1
Now plugging this into the first equation, we have:
x + 2 + 6 = 9
x + 8 = 9
Subtract 8 from both sides
x = 1

Answer:
b
Step-by-step explanation:
Answer:
option B
Step-by-step explanation:
a is located in the left side of 0 . HENCE IT IS A NEGATIVE NUMBER . b & c are on the right side of 0. HENCE BOTH ARE POSITIVE NUMBER
In option B , it's given that -a > -c . If we'll verify this statement , we'll find that when we put the negative sign in a , the all totla value of a becomes positive BECAUSE 'a' WAS A NEGATIVE NUMBER.
Now if we put a negative sign in c , the all total value becomes negative BECAUSE 'c' WAS A POSITIVE NUMBER.
By comparing -a & -c , we'll get to know that :-
-a > -c

What is the rate of change (Slope) of the cost with respect to the number of miles for the Yellow Cab Company?
Answer:
The slope would be 2
Step-by-step explanation:
All you do is pick two order pairs: (2,6) and (4,10), then you do y1 - y2, so 10-6 to get 4 then do x1 - x2, so 4 - 2 which is 2, then you divide 4 by 2 to get 2.

What is the value of 2cos2(105⁰) − 1?
Step-by-step explanation:
-1 - root3
The value of the given expression 2cos2(105⁰) − 1 is,
⇒ - 1 - √3
What is trigonometric functions?A right-angled triangle's angle can be related to side length ratios using trigonometric functions, which are real functions in mathematics. They are extensively used in all geosciences, including navigation, solid mechanics, celestial mechanics, geodesy, and many others.
We have to find the value of;
⇒ 2cos2(105⁰) − 1
Now, We can Plug 105° = θ
So, the expression becomes,
⇒ 2cos2θ - 1
Using the formula;
cos2θ = 1 - 2sin^2θ
We get;
⇒ 2cos2θ - 1 = 2(1-2sin^2θ) - 1
= 2 - 4sin^2θ - 1
⇒ 2cos2θ - 1 = 1 - 4sin^2θ
Now, Again plug θ = 105°
⇒ 2cos2(105°) - 1 = 1 - 4sin¹⁰⁵
⇒ 2cos2(105°) - 1 = -1 - √3
Hence, The value of the given expression is,
⇒ (-1 - √3)

Answer:
It would be -13
Step-by-step explanation:
Answer:
-13
Step-by-step explanation:
You need to separate the 8 from each side of the equation. Picture it like this:
-104= 8 (multiplied by) x
To separate 8 from the variable, you need to divide that side by 8. Similarly, you need to do the same thing to the other side.
-104/8=8x/8
-13=x
