Answer: y = (-1/2)x + 2
Concept:
When two lines are perpendicular to each other, their slopes are negative reciprocals.
The reciprocal of a number is 1 divided by the number.
In other words, it is the image opposite of a term.
Solve:
Given information
Given line = y = 2x - 5
Point = (-4, 4)
Find the slope of the line
Given the line is perpendicular to the line y = 2x - 5, the slope of the line would be negative reciprocal of the line y = 2x - 5.
Slope of line [y = 2x - 5] = 2
Slope of new line = (-1/2)
Find the y-intercept by substituting the given point
Equation of the new line: y = (-1/2)x + b
b = y-intercepty = (-1/2)x + b
4 = (-1/2) (-4) + b
4 = 2 + b
4 - 2 = 2 + b - 2
b = 2
Finalize the equation of the line
Slope = -1/2
Y-intercept = 2
[tex]\boxed{y=-\frac{1}{2}x+2 }[/tex]

A teacher has 104 pieces of candy if there are 13 students in the candies divided evenly how many pieces will each student get
Every student will get 8 candies.
What is division?Division is a process of splitting a specific amount into equal parts.
Given that, A teacher has 104 pieces of candy, which she equally divides to her 13 students.
Therefore, for calculating how many candies each of them is getting, we will divide total number of candies to the total number of students,
Therefore, 104/13 = 8
Hence, we get that every student will get 8 candies.

Can someone please explain how to find a cofunction with the same value as the given expression. Please explain step by step.
Ex. How would you find the cofunction of sin 7°
Answer:
Step-by-step explanation:
-the angles need to add to 90° because they have to e complementary
- the cofunctions come in pairs (sin and cos, tan and cot, sec and csc)
for sin 7°
we know that function sin is paired with cos , and that the angles needs to add to 90° so we have 7° + 83° =90°
sin 7° = cos 83°, cos 83° is a cofunction of sin 7°

Answer:
[tex] \frac{11}{b - 1} = \frac{6}{b + 1} \\ 11(b + 1) = (b - 1).6 \\ 11b + 11 = 6b - 6 \\ 11b + 11 - 11 = 6b - 6 - 11 \\ 11b - 6b = 6b - 17 - 6b \\ 5b = - 17 \\ \frac{5b}{5} = \frac{ - 17}{5} \\ b = \frac{ - 17}{5} \\ b = - 3.4[/tex]
[tex]\boxed{\underline{\bf \: Answer}}[/tex]
[tex] \sf \frac{11}{b + 1} = \frac{6}{b + 1} \\ [/tex]
Multiply both sides of the equation by [tex]\left(b-1\right)\left(b+1\right)[/tex], the least common multiple of b-1,b+1.
[tex]\sf\left(b+1\right)\times 11=\left(b-1\right)\times 6 [/tex]
Use the distributive property to multiply b+1 by 11.
[tex]\sf11b+11=\left(b-1\right)\times 6 [/tex]
Subtract 6b from both sides.
[tex]\sf11b+11-6b=-6 [/tex]
Combine 11b and -6b to get 5b.
[tex]\sf5b+11=-6 [/tex]
Subtract 11 from both sides.
[tex]\sf5b=-6-11 [/tex]
Subtract 11 from -6 to get -17.
[tex]\sf5b=-17 [/tex]
Divide both sides by 5.
[tex]\sf \: b=\bf\frac{-17}{5} [/tex]

Answer:
-Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:
x= -1/2
Decimal Form:
x=0.5
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer: x = -1/2
Step-by-step explanation:
1/2 x - 3/10 = 5/2 x + 7/10
-1/2 x on both sides
-3/10 = 4/2 x +7/10
subtract 7/10 from both sides
-1 = 4/2x
simplify
2x = -1
divide 2 on both sides
x = -1/2

8(b ÷ 2) - (c + 4)
(Putting values of b = 1/2 and c = 1/4)
[tex] = 8( \frac{1}{2} \div 2) - ( \frac{1}{4} + 4)[/tex]
[tex] = 8( \frac{1}{2} \times \frac{1}{2} ) - ( \frac{1 + 16}{4} )[/tex]
[tex] = 8 \times \frac{1}{4} - \frac{17}{4} [/tex]

Write equation to touch all the stars
Answer:
y=-1/2x+3
Step-by-step explanation:
You're Y coordinate is going to equal the slope, or rise over run (aka rate of change.)
-1/2 is the rate of change, as the line goes up one, over negative two.
Then, add the Y-intercept, which is three, and you've got your equation!
