Answer:
y = -1/5x - 2
Step-by-step explanation:
All you need is a perpendicular slope and any y-intercept.
Perpendicular slope is a negative reciprocal so:
5 → -1/5
y-intercept doesn't matter so:
y = -1/5x - 2
Answer:
y= -1/5x +4
Step-by-step explanation:
To find a perpendicular line, you need the negative reciprocal of the slope, in this case it is 5 and -1/5.

If you spin the spinner two times, how many possible outcomes are there?
Answer:
1 Answer. The chance of anding on A for one spin is 90+45360=38. So the probability of that happening twice in a row is 38×38=964.

Sami was asked to solve the following system of equations using substitution.
y=6x -4
y=2x
Here is the work that sami did:
2x = 6x -4
8x = -4
x = -0.5
And then to find y: y= 2 (-0.5) = -1
so Sami's answer for the point of intersection was (-0.5, -1).
Clearly state Sami's one error and then give the correct ordered pair for where the lines cross.
Answer:
see explanation
Step-by-step explanation:
Sami's error is in the second line of working
2x = 6x - 4 ← correct substitution ( subtract 6x from both sides, Sami has added 6x )
- 4x = - 4 ← correct second line ( divide both sides by - 4 )
x = 1
Substitute x = 1 into either of the 2 equations and evaluate for y
Substituting into the second equation
y = 2x = 2(1) = 2
solution is (1, 2 )
3/4x=2x−5
NEED ANSWER WITHIN THE NEXT HOUR PLEASE GIVING 20 PTS!!!
Answer:
x = 4
Step-by-step explanation:
1. Write the equation
3/4x = 2x - 5
2. Get the variables on the same side
Let's subtract 2x! Now, since math is a veryyy jealous subject, you're going to do it on the other side too!
-1.25x = -5
3. Divide both sides by -1.25
x = 4
Thank you for the points!!!

Answer:
AB = 10 m
Step-by-step explanation:
Given that <ACB = <ECD, then triangles ABC and EDC are similar.
Let the height of the solar panel (AB) be represented by x. Thus by comparing the triangles, we have;
[tex]\frac{x}{6}[/tex] = [tex]\frac{45}{75}[/tex]
45x = 6 x 75
45x = 450
x = [tex]\frac{450}{45}[/tex]
x = 10
The height of the solar panel is determined to be 10 m.
A 14-in. diameter pizza is cut into 6 equal
slices. About how many square inches of
pizza are in each slice? Round to the
nearest square inch.
Answer:
25.64 in² per slice
Step-by-step explanation:
14 diameter = 7 radius
area of whole = π7² = 153.86 in²
153.86/6 = 25.64 in²

Find the area of the object
Answer:
2π + 24 m² = 30.3 m²(3 s.f.)
Step-by-step explanation:
Area of rectangle: l x w
6 x 4 = 24 m²
Area of semicircle: πr²/2
r = 4/2 = 2
π x 2² / 2
4π / 2
2π
Total area: 2π + 24 m² = 30.3 (3 s.f.)

7. Which expression is equivalent to 3-4.3^6?
4. Two consecutive even numbers are such that the sum of the larger number and three times the smaller number is 42. Find the two numbers.
Answer: The two numbers are 10 and 12.
Step-by-step explanation:
Let the two consecutive numbers are x and x +2.
As per given, we have
[tex](x+2)+3x=42\\\\\Rightarrow\ 4x+2=42\\\\\Rightarrow\ 4x=40\\\\\Rightarrow\ x=10[/tex]
Smaller number = 10
Larger number = 10+2=12
Therefore, The two numbers are 10 and 12.
what is the slope of the line?
What is the y-intercept?
Write the equation of the line?
Answer:
The slope is 2
The y-intercept is 3
The equation is y = 2x +3
Step-by-step explanation:
The equation goes up 2 squares and over 1 square. 2/1 = 2
For y-intercept, look at the y-axis
The equation is supposed to be written as y = mx + b
m being the slope and b being the y-intercept.

Please help! You don't have to show work, just tell me the answer
Answer:
1A. acute. all of the angles are under 90%. acute is under 90%, right is 90%, and obtuse is over 90%
2A. scalene. isosceles is all sides are the same length, and equilateral is all sides are the same length AND all the angles are 60%. with scalene all sides can be different lengths, and angles can be different
3. no. the rule for making a triangle is that any 2 sides added up, must be more than the 3rd side. so 6+2, 6+4 work, but 2+4 is 6, which is not greater than 6, the third side

Determine the area of the parallelogram.use proper units
Answer:
180 in^2
Step-by-step explanation:
to find the height you need to look at the triangle and apply pythagorean theorem
5^2=x^2=13^2
25+x^2=169
x^2=144
x=12
now we can find the area of the parallelogram:
b*h=area
15*12=180 in^2
The area of the parallelogram is 180 in^2
