Please Help me i need help Pleaaaasssseeeee im not good at numbers ._. Find the equation of the line that passes through the point (2,-6) and is perpendicular to the line y=1/4x-2.
Answer:
y = -4x + 2
Step-by-step explanation:
1) Find perpendicular slope
1/4 = -4
2) Plug in x and y
y = -4x + b
((((( y = -6, x = 2 ))))))
-6 = -4(2) +b
-6 = -8 + b
2 = b
3) Return to equation but plug in b, but not x and y
y = -4x + 2
Could anyone help me out here?
Answer:
It the first one BC a and b connects so it make it a 1 one

Complete the equation of the line through (-9,7)and(-6-3)use exact numbers
Answer:
[tex]\boxed{y = -\dfrac{10}{3}x - 23}[/tex]
Step-by-step explanation:
Equation of a straight line: y = kx + b
Points: (-9,7) and (-6,-3)
Сompose the system of equations:
[tex]\displaystyle \left \{ {{7=-9k + b} \atop {-3=-6k + b}} \right[/tex] [tex]\displaystyle \left \{ {{b= 7 + 9k} \atop {b=6k - 3}} \right \Longrightarrow 7 + 9k = 6k - 3[/tex]
[tex]7 + 9k = 6k - 3[/tex]
[tex]3k = -10|:3[/tex]
[tex]k = -\dfrac{10}{3}[/tex]
[tex]b = 6k - 3= 6 \cdot \dfrac{-10}{3} - 3 = 2 \cdot (-10) - 3 = -20 - 3 = -23[/tex]
[tex]y = -\dfrac{10}{3}x - 23[/tex]

ava has a number cube with six equal sides numbered one through six if she rolls the number cube 60 times how many times can she expect to land on a greater number
Answer:
10
Step-by-step explanation:
Since there are six sides, and only one side has a 3 on it, you will roll a 3 1/6 times. So multiply 1/6 by 60 and you get 10

How long did it take for the car to be under surveillance before it could finally stop on the side of the road? Did the driver of the car really break the speed limit of 100 km/hr.? Explain
Answer:god duh
Step-by-step explanation:
Mr. Murphy is designing a rectangular concrete fire pit. The concrete sides and bottom will be 5 inches thick. The interior length will be 3 times the interior
height and the interior width will be 2 times the interior height. What should the outer dimensions of the fire pit be if the inner volume is to be 6000 cubic
inches?
Enter the correct values in the boxes.
*15 is correct but 25 & 35 are wrong ..*
For the outer dimensions: length = 35 inches, width = 25 inches, and height = 15 inches.
Step-by-step explanation:
For the interior;
volume = 6000
length, l = 3h
width, w = 2h
height = h
But,
Volume of a cuboid = length x width x height
So that;
6000 = 3h x 2h x h
6000 = 6
Divide through by 6 to have;
1000 =
h =
= 10
Thus, the height is 10 inches. Thus;
length, l = 3h = 3 x 10 = 30 inches
width, w = 2h = 2 x 10 = 20 inches
For the outer dimension, since the concrete sides and bottom would be 5 inches thick. Then its dimension are;
length, l = 30 + 5 = 35 inches
width, w = 20 + 5 = 25 inches
height = 10 + 5 = 15 inches

-u+14=170 solve for u
Answer:
u = -156
Step-by-step explanation:
-u + 14 = 170
- 14 - 14
-u = 156
u = -156
Hope this helps!
Answer:
u = -156
Step-by-step explanation:
-u+14=170
-u+14-14=170-14
-u=156
-u/-1=156/-1
u=-156
Given the diagram below, find the value of MQR.
Answer:
The answer is MQR= 48 degrees
Step-by-step explanation:
I got this answer from process of elimination. The first option was 48 degrees so I divided 48 by 3 and got 16 then I applied to (2x + 16): (2(16)+16) and got 48 which comfirmed my answer. Also I took the test and it was right so I know its correct.
Casey earned $220 selling baked goods. Her expenses were $2.50 per baked good. Which equation can be used to find b, the number of baked goods Casey would have to sell in order to make a profit of exactly n$100?
a. 220 - 2.50b = 100
b. 220 + 2.50b = 100
c. 220b - 2.50 = 100
d. 220b + 2.50 = 100
The correct answer would be equation letter A.

What is the equation of the line shown in the graph?
Answer:
y = -1x -2
Step-by-step explanation:
[] First, we can tell it is negative because it is going from top-left to bottom-right
[] Next, it intercepts the y-axis at -2, so our b is -2
[] Last, since it is graphed, we can use "rise over run"
() We move down one and to the right one, this becomes 1/1, which becomes a slope of 1, so our m is -1 since it is negative
Now let's plug our pieces in
Slope-intercept form is y = mx + b
y = mx + b
y = (-1)x + b
y = -1x -2

Answer:
Is this the question [tex]x^{2}[/tex]+3x+3=−2x−3
Step-by-step explanation:
[tex]x^{2}[/tex]+3x+3=−2x−3
Step 1: Subtract -2x-3 from both sides.
[tex]x^{2}[/tex]+3x+3−(−2x−3)=−2x−3−(−2x−3)
[tex]x^{2}[/tex]+5x+6=0
Step 2: Factor left side of equation.
(x+2)(x+3)=0
Step 3: Set factors equal to 0.
