What method can you use to prove sides or angles are congruent AFTER you have proven two triangles are congruent to each other?
Answer: Side Angle Side (SAS) is a rule used to prove whether a given set of triangles are congruent. In this case, two triangles are congruent if two sides and one included angle in a given triangle are equal to the corresponding two sides and one included angle in another triangle.

Step-by-step explanation:
Consider these functions:
f(x)=3x - 7
g(t)=1+1
What is the value of f(g(3))?
A.-1
B.0
C.3
D. 5
Answer:
A(-1)
Step-by-step explanation:
First, we will replace any x in g(x) with 3
g(x)=(3+1)/(3-1)=4/2=2
Thwn replace any x in f(x) with 2
f(x)=3(2)-7=6-7=-1 ⇒A

Solve the system of equations.
5x + 2y = 12
5x – 2y = 28
Answer:
x=4 y=-4
Step-by-step explanation:
Step: Solve5x+2y=12for x:
5x+2y=12
5x+2y+−2y=12+−2y(Add -2y to both sides)
5x/5=−2y+12/5
x= −2/5y+12/5
−2/5y+12/5 for x in5x−2y=28
5(−2/5y+12/5)−2y=28
−4y+12=28(Simplify both sides of the equation)
−4y+12+−12=28+−12(Add -12 to both sides)
−4y=16
−4y/−4=16/−4
(Divide both sides by -4)
y=−4
Substitute −4 for y in x=−2/5y+12/5
x= −2/5y+12/5
x=−2/5(−4)+12/5
x=4

Derrick is placing a right triangle in the coordinate plane. He knows that the longer leg is 3 times the length of the shorter leg. He places the longer leg on the x-axis.
What coordinates should he assign to the third vertex of the triangle?
Answer:
Longer leg is placed on X axis.
Let the longer leg be at A(0,0) and B(3 a,0),or (-3 a,0), which is either base or altitude.
AB= 3 a
As longer leg = 3 × shorter leg
Shorter leg should be placed either at (0,a) or (0,-a) maintaining triangle as right angled triangle.

Brett bought 2 shirts. One cost $4 more than 3 times the other. Together, the 2 shirts cost
him $72.
HELP PLEASE.
Answer:
one costs 17 dollars the other costs 55 dollars
Step-by-step explanation:
we have to make 2 equations using variables
x=shirt 1
y= shirt 2
y+x=72
x=3y+4
then substitute 3y+4 for x in the first equation
y+3y+4=72
subtract 4 and add y and 3y
4y=68
divide by 4
y= 17
use this for y in the second equation
x=3(17)+4
x=51+4
x=55
3x-y=6
-4x+2y=-8 solve using substitution method

x= 3y+2

When a baseball is hit by a batter the height of the ball age of T at time TT equals zero is determined by the equation age of T equals -16 T squared +64 2+ 4FT is in seconds for which interval of time is the height of the bar greater than or equal to 52 feet
Answer:
1 ≥ t ≤ 3
Step-by-step explanation:
Given
h(t) = -16t² + 64t + 4
Required
Determine the interval which the bar is at a height greater than or equal to 52ft
This implies that
h(t) ≥ 52
Substitute -16t² + 64t + 4 for h(t)
-16t² + 64t + 4 ≥ 52
Collect like terms
-16t² + 64t + 4 - 52 ≥ 0
-16t² + 64t - 48 ≥ 0
Divide through by 16
-t² + 4t - 3 ≥ 0
Multiply through by -1
t² - 4t + 3 ≤ 0
t² - 3t - t + 3 ≤ 0
t(t - 3) -1(t - 3) ≤ 0
(t - 1)(t - 3) ≤ 0
t - 1 ≤ 0 or t - 3 ≤ 0
t ≤ 1 or t ≤ 3
Rewrite as:
1 ≥ t or t ≤ 3
Combine inequality
1 ≥ t ≤ 3
What is the inverse of the function f(x) = x +3
Answer:
h(x) = x-3
Step-by-step explanation:
The inverse of a function works such that f(h(x)) = x. Also, f(h(x)) = h(x) + 3. Thus, x = h(x) +3 -> h(x) = x-3

Write an equation for the proportional relationship. Can you compare these two tables?
Answer:
Y=1.88x
Step-by-step explanation:
x1=2 x2=3, y1=3.76 y2=5.64
(2, 3.76) (3, 5.64)
m(slope) =5.64-3.76/3-2
m=1.88
y-3.76=1.88(x-2)
y-3.76=1.88x-3.76
Y=1.88x

Answer:
1. Bill spent $3 on each card.
3. Penny can buy 7 gifts.
4. $16.
I did 3 of them for you. :)
Step-by-step explanation:
1) You subtract 3 from 15 (15-3) which equals 12.
Divide $36 by 12 (36/12) which equals $3 each.
3) You add 26+16 which equals 42.
Divide 42 by 6 which equals 7.
4) You subtract 16 from 24 (24-16) which equals 8.
Multiply 8 by 2(8*2) which equals $16.
Write the equation of the line parallel to y = 3x + 3, that passes through (-3, 10).
y=3x+19
Step-by-step explanation:
equation parallel to y=3x+3 means having the same gradient .Here gradient is 3 where you equate equation with y=mx +c where m is the gradient and c is the y-intercept
Equation of line y=3x+c
you must find c ,replace point (-3,10) in equation y=3x+c
10=3(-3)+c
10=-9+c
10+9=c
c=19
equation of line parallel to y=3x+3 that passes through(-3,10) is y=3x+19

How do you solve problems involving sequence? Discuss the mathematics concepts and principles applied when solving problems involving sequence
Step-by-step explanation:
Sequence is defined as arrangement f numbers in a specific or defined pattern. Sequence are categorized into
1) Arithmetic
2) Geometric
Arithmetic sequence are characterized by their common difference while Geometric sequence are characterized by their common ratio.
Given a sequance of numbers say;
T1, T2, T3...
The first term "a" of the sequence is T1
Common difference d = T2-T1 =T3-T2
Common ratio = T2/T1 = T3/T2
The formula for calculating nth term of an Arithmetic sequence is expressed as;
Tn = a+(n-1)d
a is the first term
n is the number of terms
d is the common difference
The nth term of a Geometric sequence is expressed as;
Tn = ar^{n-1}
r is the common ratio
Numbers are arranged in a sequence when they follow a predetermined or established pattern. Sequences can be divided into
1) Mathematics
2) Graphitic
Geometric sequences are characterized by their common ratio, whereas arithmetic sequences are distinguished by their common difference.
Suppose a sequence of numbers is given;
T1, T2, T3...
The sequence's initial term "a" is T1.
common distinction d = T2-T1 =T3-T2
T2/T1 Common Ratio T3/T2
The following is the formula for finding the nth term in an arithmetic sequence:
Tn = a+(n-1)d
The first term is a.
The number of terms is n.
d is the typical discrepancy
The nth term of a Geometric sequence is expressed as;
[tex]T_{n} =ar^{n-1}[/tex]
r is the common ratio

The sum of two numbers is 13. Their product is - 1850. Find the numbers.
Answer:
Let m and n be the numbers. Then:
m+n=13 and
mn=40
Then:
n=13-m
So:
m(13-m)=40
13m-m²=40
m²-13m+40=0
(m-8)(m-5)=40
m=8 or 5
Thus, the two numbers are 8 and 5……………….
