Write the equation of a line perpendicular to y=-2x+1 that passes through the point (2,3)
Answer:
y = 1/2x + 2
Step-by-step explanation:
First you have to determine the slope which is the opposite reciprocal of the slope of the line given.
So we take the slope -2 and reciprocate and by flipping the numerator and denominator which makes it -1/2.
Then we have to make it the opposite, like making a negative into a positive or a positive into a negative. So that would make it positive 1/2.
We now have the slope which is 1/2 and not we have to make sure it goes through point (2,3).
To do that, we must adjust the y-intercept until it goes through that point. We result in getting the y-intercept of 2.
The answer is y = 1/2x + 2
Answer:
y = [tex]\frac{1}{2}[/tex] x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x + 1 ← is in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex] , thus
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (2, 3) into the partial equation
3 = 1 + c ⇒ c = 3 - 1 = 2
y = [tex]\frac{1}{2}[/tex] x + 2 ← equation of perpendicular line

Describe the steps in solving the linear equation 3(3x − 8) = 4x + 6.
Answer:
x=6
Step-by-step explanation:
3(3x-8)=4x+6
First you would distribute the 3 on the L side to the parenthasies
9x-24=4x+6
Then, you would subtract 4x from both sides because it is the smallest X value
5x-24=6
Add 24 to both sides (inverse operations)
5x=30
divide both sides by 5
x=6
the answer is x=6
3(3x − 8) = 4x + 6.
9x-24 =4x+6
9x-4x=6+24
5x=30
5 5
x=6

There were 475,000 children at a state fair.
There were 26,000 more adults than children at
the state fair. How many adults were there.
How many people were there in all? pls help
Answer:
501,000 adults 976,000 people total
Step-by-step explanation:
First step is adding 26,000 to 475,000 to find the number of adults, you get 501,000
Then you add 501,000 to 475,000 to get the total number of people, you get 976,000
A phrase is considered a mathematical expression if it contains at least two numbers or variables and one or more mathematical operations.
If 501,000 grownups total then 976,000 people.
What is meant by an expression?An expression, also known as a mathematical expression, is a finite combination of symbols that are well-formed in accordance with context-dependent rules.
Mathematical expressions consist of at least two numbers or variables, at least one math operation, and a sentence. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)
A phrase is considered a mathematical expression if it contains at least two numbers or variables and one or more mathematical operations.
One mathematical expression makes up a term. It could be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in some terms have a number in front of them. A coefficient is the number placed before a term.
Given:
There were 475,000 children at a state fair.
There were 26,000 more adults than children at the state fair.
Number of adults = 26,000 × 475,000 = 501,000
Total number of people = 501,000 × 475,000 = 976,000
501,000 grownups total 976,000 people
Therefore, 501,000 grownups total 976,000 people.

Answer: y=17 x=10
Step-by-step explanation:
so they have equal measures and they’re a linear pair (make a line) and a line is 180° so that would means you can set both equal to 90°
9y-63=90 and 9x=90
so for the first one you subtract 63 from 90 then divide by 9 to get 17
the next one you just divide by 9 to get 10 therefor y=17 and x=9

Triangle JKL is reflected across line a to form triangle MNO. Which one of these is true?
Segment JK is congruent to Segment MN, Segment KL is congruent to segment NO, and the angle K is congruent to the angle N.
Therefore, the answer choice that is true when [tex]\triangle JKL[/tex] is reflected over a line to form [tex]\triangle MNO[/tex] is: d. [tex]\overline{JK} \cong \overline{MN}, \overline{KL} \cong \overline{NO}, \angle K \cong \angle N[/tex]
Reflecting a shape or figure over a line is somewhat similar to when you place an object before a mirror.
In the reflection of triangle JKL across a line, triangle MNO is the mirror image of triangle MNO.
In essence, the corresponding angles and corresponding sides of both triangle JKL and triangle MNO will be congruent to each other.Thus:<K is congruent to <N
<J is congruent to <M
<L is congruent to<O
[tex]\overline{JK} \cong \overline{MN}\\\\\ \overline{KL} \cong \overline{NO}\\\\ \overline{JL} \cong \overline{MO}[/tex]

Answer: 7. p=1.49
8. a= 1.05
Step-by-step explanation:
Answer:
p = 1.5 & s = 7
Step-by-step explanation:
7. [tex]\frac{0.45}{4.2}[/tex] = [tex]\frac{p}{14}[/tex]
0.45(14) = 4.2p ⇒ Cross-multiply the terms
6.3 = 4.2p
p = [tex]\frac{6.3}{4.2}[/tex] ⇒ Divide 6.3 by 4.2 to get p by itself (solve for p)
p = 1.5
8. [tex]\frac{2.4}{6}[/tex] = [tex]\frac{2.8}{s}[/tex]
2.4s = 6(2.8) ⇒ Cross-multiply the terms
2.4s = 16.8
s = [tex]\frac{16.8}{2.4}[/tex] ⇒ Divide 16.8 by 2.4 to get s by itself (solve for s)

The quotient of 24 and x equals 14 minus 2 times x (into an equation don’t solve)
Answer:
24 / x = 14 - 2x
Step-by-step explanation:
Quotient means division (÷ or /)
Quotient of 24 and x = 24 ÷ x
24 ÷ x is equivalent to 24 / x
14 minus 2 times x = 14 - 2x
So, the equation is
24 / x = 14 - 2x

3n+1=19 so i'm learning to solve 2 step equations in pre algebra but i don't really understand.
Answer:
n = 6
Step-by-step explanation:
Simplifying
3n + 1 = 19
Reorder the terms:
1 + 3n = 19
Solving
1 + 3n = 19
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-1' to each side of the equation.
1 + -1 + 3n = 19 + -1
Combine like terms: 1 + -1 = 0
0 + 3n = 19 + -1
3n = 19 + -1
Combine like terms: 19 + -1 = 18
3n = 18
Divide each side by '3'.
n = 6
Simplifying
n = 6
Answer:
n = 6
Step-by-step explanation:
3n + 1 = 19
Subtracting 1 from both sides:
3n + 1 - 1 = 19 - 1
3n = 18
Dividing both sides by 3:
3n/3 = 18/3
Simplifying:
18/3 = 6
n = 6

Carrie makes 27 liters of lemonade. 8 people share the lemonade equally. Which statement is true? a Each person will receive less than 2 liters. b Each person will receive between 2 and 3 liters. c Each person will receive between 3 and 4 liters. d Each person will receive more than 4 liters.
Answer:
The correct option is;
a. Each person will receive between 3 and 4 liters
Step-by-step explanation:
The volume of lemonade Carrie makes = 27 liters
The number of people that share the lemonade = 8
The volume of lemonade each person receives = 27/8 = 3.375liters
Each person will receive more than 3 liters but less than 4 liters of lemonade
Therefore, the correct option is each person will receive between 3 and 4 liters.
Answer:
Each person will receive between 3 and 4 liters.
