Write the slope intercept form of the equation of the line passing through (-4,6) and perpendicular to y=-2x-5.
Answer:
[tex]y=\frac{1}{2} x+8[/tex]
Step-by-step explanation:
Hi there!
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
1) Determine the slope (m)
Perpendicular lines will always have slopes that are negative reciprocals of each other. For example, two perpendicular lines might have slopes of 3 and -1/3.
After observing the equation y=-2x-5, we can conclude that the slope is -2. Therefore, a line perpendicular to this line would have a slope of 1/2. Plug this into [tex]y=mx+b[/tex]:
[tex]y=\frac{1}{2} x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=\frac{1}{2} x+b[/tex]
Plug in the given point (-4,6)
[tex]6=\frac{1}{2}(-4)+b\\6=-2+b[/tex]
Add 2 to both sides
[tex]6+2=-2+b+2\\8=b[/tex]
Therefore, the y-intercept is 8. Plug this back into [tex]y=\frac{1}{2} x+b[/tex]:
[tex]y=\frac{1}{2} x+8[/tex]

The area of a triangle is 169 square meters. The base of the triangle is twice the height. Find the base and height.
I would like the answer and how to get it (show work).
Thanks!
Answer:
The base of the triangle has a length of 26 meters, and the height of the triangle has a length of 13 meters.
Step-by-step explanation:
Equation to find the height: [tex]\frac{2x*x}{2} = 169[/tex] ⇒ [tex]x^2=169[/tex] ⇒ [tex]x=13[/tex] meters.

dont just comment for points.
Answer:
that looks good
Step-by-step explanation:
Rearrange 3x - 6y = -2 to the form y=mx + c
3x - 6y = -2
-6y = -3x - 2, divide through by -1
6y = 3x + 2, divide through by 6
y = 3x/6 + 2/6
y = x/2 + 1/3
Answer:
y = 1/2x - 1/3
Step-by-step explanation:
subtract 3x from each side first to get:
-6y = -3x - 2
divide each side by -6 to get:
y = 3/6x - 2/6
simplify:
y = 1/2x + 1/3
If the height of the parallelogram shown is increased by 1 cm and the base is increased by 2 cm, what is the area of the new parallelogram?
A parallelogram with a base of 9 centimeters and a height of 4 centimeters.
28 cm2
39 cm2
55 cm2
60 cm2
My main problem: The base isn't at the top, so therefore I am confused. It should be on top of the shape but it is not. If it was I could figure it out.
So sorry I messed it up I let you down :(
Answer:
55 cm²
Step-by-step explanation:
In a parallelogram, the top base is equal to the bottom base (and the sides are equal to each other too!)
So the top and bottom base are both 9, and the left and right sides are both 5.
So, to solve, we need to use the equation:
(4 + 1) * (9 + 2) = 5 * 11 = 55 cm²
Which expression has a value that is less than the base of that expression? A. 2^3 B. (5/6)^2 C. 3^1 D. 4^4
Answer:
B. (5/6)^2
Step-by-step explanation:
A. 2^3
= 2 × 2 × 2
= 8
The base is 2
Therefore, the expression is greater than the base
B. (5/6)^2
= 5/6 × 5/6
= 5*5 / 6*6
= 25/36
Base = 5/6 = 0.833
Expression =25/36 = 0.694
Therefore, the expression is less than the base
C. 3^1
= 3
The base is 3
Therefore, the expression is equal to the base
D. 4^4
= 4 * 4 * 4 * 4
= 256
The base is 4
Therefore, the expression is greater than the base
The correct answer is B. (5/6)^2
19, 12, 3, 6, 18, 20, 4, 4, 8, 12, 16, 20, 10, 1, 7, 8 1. Find the range of the data
Answer:
The highest observation =20
The lowest observation = 1
Range of the data = 20-1
= 19(ans)
Answer:
The range is 19
Step-by-step explanation:
To calculate the range of a set of data, you order the numbers from highest to lowest (ex; 20,20,19,18,16,12,12,10,8,8,7,6,4,4,3,1,1) then you subtract the highest number from the lowest number (ex; 20 - 1)

Given:
Total number of students = 27
Students who play basketball = 7
Student who play baseball = 18
Students who play neither sports = 7
To find:
The probability the student chosen at randomly from the class plays both basketball and base ball.
Solution:
Let the following events,
A : Student plays basketball
B : Student plays baseball
U : Union set or all students.
Then according to given information,
[tex]n(U)=27[/tex]
[tex]n(A)=7[/tex]
[tex]n(B)=18[/tex]
[tex]n(A'\cap B')=7[/tex]
We know that,
[tex]n(A\cup B)=n(U)-n(A'\cap B')[/tex]
[tex]n(A\cup B)=27-7[/tex]
[tex]n(A\cup B)=20[/tex]
Now,
[tex]n(A\cup B)=n(A)+n(B)-n(A\cap B)[/tex]
[tex]20=7+18-n(A\cap B)[/tex]
[tex]n(A\cap B)=7+18-20[/tex]
[tex]n(A\cap B)=25-20[/tex]
[tex]n(A\cap B)=5[/tex]
It means, the number of students who play both sports is 5.
The probability the student chosen at randomly from the class plays both basketball and base ball is
[tex]\text{Probability}=\dfrac{\text{Number of students who play both sports}}{\text{Total number of students}}[/tex]
[tex]\text{Probability}=\dfrac{5}{27}[/tex]
Therefore, the required probability is [tex]\dfrac{5}{27}[/tex].

You start driving north for 4 miles, turn right, and drive east for another 4 miles. At the end of driving, what is your straight line distance from your starting point? Round to the nearest tenth of a mile.
The straight line distance between the start and finish point is required.
The straight line distance is 5.7 miles.
Pythagoras theorema = Distance traveled north = 4 miles
b = Distance traveled east = 4 miles
c = Straight line distance
The angle between the two paths is ninety degrees so, the Pythagoras theorem can be applied here.
Applying the Pythagoras theorem
[tex]c=\sqrt{a^2+b^2}\\\Rightarrow c=\sqrt{4^2+4^2}\\\Rightarrow c=4\sqrt{2}\\\Rightarrow c=5.7\ \text{miles}[/tex]

f(x) = x2. What is g(x)?
f(x) = x2

g(x)/5
O A. g(x) = -x - 3
O B. g(x) = x2 - 3
O c. g(x) = -x2
D. g(x) = -382
If function f(x)= x² then g(x) is -x² - 3 , option A is correct.
What is a function?A relation is a function if it has only One y-value for each x-value.
The reflection in the x-axis changes the sign of the y-coordinate. So, the reflection of f(x) = x² in the x-axis is g(x) = -x².
Secondly, the downward shift of 3 units means subtracting 3 from the y-coordinate.
So, the transformation applied to f(x) to get g(x) is reflection in the x-axis followed by a downward shift of 3 units.
g(x) = -x² - 3 is the result of applying a reflection in the x-axis followed by a downward shift of 3 units to the function f(x) = x².
Hence, if function f(x)= x² then g(x) is -x² - 3 , option A is correct.
