“The new coordinates are (3, -2).”
State the error.
Write the rule.
What is the correct answer?
Answer:
(3,2)
Step-by-step explanation: Because -3 and -2 are negative so when you reflect them the opposite of a negative is positive. So the answer is (3,2) HOPE THAT HELPS.

4x
Step-by-step explanation:
the -8 and +8 cancel out
x and 3x are both positive so add them
you're left with 4x
Simplifying is the same as solving this question. I'll give steps instead.
x - 8 + 3x + 8

What is the measurement of angle 1 plz help me !
Answer:
ANGLE 1 = 40°
Step-by-step explanation:
angle 1 = angle 2 ------(alternate interior angles)
2x + 20 = 3x + 10
20 - 10 = 3x - 2x
x = 10.
Angle 1 = 2x + 20 = 2(10) + 20 = 20 + 20 = 40°.

A sheet of bad paper is cut into 12 equal parts. What percent of the whole is 3 parts? This is easy, dont be afraid to ask for help
Answer: 25percent
Step-by-step explanation: Divide 12 by 3 and you'll get 4.
That means 1/4 or a quarter of the 12 is 3.
(Convert the fraction to its percentage form)
1/4 or 1 divided by 4 equals 0.25
Multiply 0.25 by 100 and you'll get 25%
Note: you can convert easier from decimal form to percentage form by moving the decimal place two spaces to the right

Answer:
P(1.5, 3.5)
Step-by-step explanation:
We need to find the average of the x and y coordinates. We do this by adding the two values, then dividing by two:
P(x1 + x2/ 2, y1 + y2/2) = P(1 + 2/ 2, 2 + 5/ 2) = P(3/2, 7/2) = P(1.5, 3.5)

Luke puts $500 into a savings account that earns 6% simple interest each year. How much money will be in the account after 3 years
Answer:
= $90
Step-by-step explanation:
I = prt
I = 500 x 0.06 x 3
I = $90
9514 1404 393
Answer:
$590
Step-by-step explanation:
The account balance is given by ...
A = P(1 +rt) . . . . simple interest rate r for t years
A = $500(1 +0.06×3) = $590
There will be $590 in the account after 3 years.
m(n+r)=s solve for n. Show two methods.
9514 1404 393
Answer:
n = (s/m) -r n = (s -mr)/mStep-by-step explanation:
1. Undo the operations done to n, in reverse order. Here, n has r added and the sum is multiplied by m. First we divide by m, then we subtract r.
m(n+r) = s . . . given
n +r = s/m . . . divide by m
n = (s/m) -r . . . subtract r
__
2. Eliminate the parentheses, then proceed as above. Subtract the added term, then divide by the coefficient of n.
m(n+r) = s
mn +mr = s . . . eliminate parentheses
mn = s -mr . . . subtract the added term
n = (s -mr)/m . . . divide by the coefficient of n
A missile is launched along a path determined by the function below, where f(x) is the height of the missile in feet x seconds after the launch.
A plane is flying nearby at a height of 650 feet.
Is the plane in danger of being hit by the missile?
Why or why not?
f(x)=-2x^2+72x
Answer:
The plane will be fine.

A 12% brine solution was mixed with a 16% brine solution to produce a 15% brine solution. How much of the 12% solution and how much of the 16% solution were used to produce 40 L of the 15% solution?
Answer:
10 liters
Step-by-step explanation:
x=12% solution, y=16% solution
x+y=40
0.12x+0.16y=6 . (12x+16x=600)
-12x-12y=-480
12x+16x=600
+ -12x-12y=-480
-------------------------------
4x=120
x=30
12% solution= 30 liters
16% solution= 10 liters
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
10L of the 12% of solutions and 30L of the 16% of solutions were used to produce 40L of the 15% of solutions.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
Let 12% brine solution be x.
Let 16% brine solutions be y.
12% brine solution was mixed with a 16% brine solution to produce 40L of the 15% solution.
This can be written as,
x + y = 40 ______(1)
0.12x + 0.16y = 0.15 x 40
0.12x + 0.16y = 6 _______(2)
We will solve for x and y.
From (1) we get,
x + y = 40
x = 40 - y _____(3)
Putting ( 3) in (2)
0.12 (40 - y) + 0.16y = 6
4.8 - 0.12y + 0.16y = 6
4.8 + 0.04y = 6
0.04y = 6 - 4.8
0.04y = 1.2
y = 1.2/0.04
y = 30
Putting in (3) we get,
x = 40 - 30 = 10
Thus,
10L of the 12% of solutions and 30L of the 16% of solutions were used to produce 40L of the 15% of solutions.

What distance would you travel in 2.5 hours if you are biking with the speed of 6.3 mph?
Answer:
15.75 milesStep-by-step explanation:
Step one:
given
time= 2.5 hours
speed= 6.3mph
Step two:
Required
Distance
we are given the speed in miles per hour, hence the distance will be in miles
we also know that the expression relating speed, distance and time is given as
speed= distance/time
thus
distance= speed*time
distance= 6.3*2.5
distance= 15.75 miles
By using expression for the speed, distance traveled by me in 2.5 hours will be
Given in the question,
Speed = 6.3 mphTime for travelling = 2.4 hoursExpression for the speed of an object is given by,
Speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]
Therefore, Distance = Speed × Time
By substituting the values of speed and the time in the expression,
Distance traveled = 6.3 × 2.5
= 15.75 miles
Therefore, distance traveled by me in 2.5 hours will be 15.75 miles.

Vertical angles are always equal. We need to set the equations inside of the parenthesis equal.
3x+26=x+20
subtract x from both sides
2x+26=20
subtract 26 from both sides
2x=-6
divide both sides by 2
