Let
a------------> first number
b------------> second number
we know that
a+b=-7--------> a=-7-b----------> equation 1
a-b=14--------> equation 2
I substitute 1 in 2
(-7-b)-b=14-------------> -7-b-b=14----------> -7-2b=14-------> 2b=-7-14
2b=-21---------> b=-10.5
a=-7-b-------> a=-7-(-10.5)-----> a=-7+10.5------> a=3.5
the answer is
the two numbers are
a=3.5
and
b=-10.5

A. a horizontal translation only
B. a horizontal translation and a glide reflection
C. a reflection across a vertical line
D. a horizontal translation and a 180° rotation
Answer:
C
Step-by-step explanation:
The strip patterns new image and pre image orientation are vertical so anything that has horizontal translation in it is wrong
C is right becuase we can reflect the b across a vertical line to get to PThe two numbers that multiply to 36 and add to -20 are

The population of a town was 489 in 1970. The population has been growing at a rate of 23 percent each year. What is the population of the town in the year 1995
Answer:
86,484
Step-by-step explanation:
The population growth can de determined by using this formula
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value = 489
R = interest rate 23
N = number of years =1995 - 1970 = 25
489 x ( 1.23)^25 = 86,484

A ticket to the state fair cost $15. The equation y=15x relates the total cost of tickets (y) to the number of tickets purchased (x). Identify the unit rate in the equation.
Answer:
15
.
Step-by-step explanation:
Ticket cost = $15
Cost equation :
y = 15x
x = number of tickets purchased
y = total cost of x tickets
The unit rate in the equation is the Coefficient of x ; which is the sales price of one ticket.
Hence, the unit rate is $15
Solve each of these equations.

1/4 of 6 feet is how many inches
Answer:
18 inches
Step-by-step explanation:
1 ft = 12 in
6 ft = ? in
Set up an equation to convert 6 feet into inches
Variable x = number of inches
1 ft/12 in = 6ft/x in
Cross multiply (feel free to ignore units for now so it doesn't get in the way of your calculations)
1 × x = 12 × 6
1x = 72
x = 72 inches
6 feet = 72 inches so replace 6 feet with 72 inches
Now let's find 1/4 of 72 inches
Set up another equation to solve
Variable y = a fourth of seventy two inches
1/4 = y/72
Cross multiply
1 × 72 = 4 × y
72 = 4y
Divide both sides by 4 to isolate variable y
72 ÷ 4 = 4y ÷ 4
18 = 1y
18 = y
Answer:
I know I already said this but
18 inches

Find the value of x in the rectangle ABCD.
Answer:
52°
Step-by-step explanation:
here's your solution
=> we know that the measure of angle of rectangle is 90°
=> 38° + X = 90°
=> X = 90° - 38°
=> X = 52°
hope it helps
Answer:
52 because D is a right angle,so 90 - 38 will give you 32
another interesting thing that can help you in math, the opposite sides if a quad are always equal, in this case D and B is equal,and C and A is equal.If you add C and a it will give you 180 degrees and if you add d and b it will give you 180 degrees
so 180 + 180

can someone help find x, y, and z
Answer:
Step-by-step explanation:
x^2=13^2-12^2
x^2=25
x=5
(sin90)/13=(sin(90-A))/5
sin(90-A)=5/13
90-A=arcsin(5/13)
A=90-arcsin(5/13)
tan(90-arcsin(5/13))=5/y
y=5/(tan(90-arcsin(5/13))
y=25/12
z^2=(25/12)^2+5^2
z=65/12
(x,y,z)=(5, 25/12, 65/12)

During a sprint, a basketball player is traveling at +3 m/s. Four seconds later, the player is traveling at –5 m/s. The average acceleration of the basketball player over the last 4 seconds is:
Answer:
the average acceleration of the basketball player over the last 4 seconds is 0.5 m/sec^2
Step-by-step explanation:
The computation of the average acceleration is shown below:
= Change in velocity ÷ change in time
= 5 - 3 ÷ 4
= 2 ÷ 4
= 0.5 m/sec ^2
Hence, the average acceleration of the basketball player over the last 4 seconds is 0.5 m/sec^2

A total of 629 tickets were sold for the school play. They were either adult tickets or student tickets. There were 71 fewer student tickets sold than adult
tickets. How many adult tickets were sold?
Answer:
350 adult tickets were sold.
Step-by-step explanation:
let x = number of adult tickets
number of student tickets -> x-71
x - 71 + x = 629
2x - 71 = 629
2x = 700
x = 350
Point E (-2, -5) is dilated from the origin by scale factor of r = 3/2. What are the coordinates of point E.
Answer:
The new coordinates of E are (-3,-15/2).
Step-by-step explanation:
Here we just need to multiply each element of this point by r.
So we have:
[tex]E_{new}(-2*(\frac{3}{2}),-5*(\frac{3}{2}))[/tex]
[tex]E_{new}(-3,-\frac{15}{2})[/tex]
Therefore, the new coordinates of E are (-3,-15/2).
