Answer:
Adult: $ 4
Student: $ 7
Step-by-step explanation:
Adult: x
Students: y
a) 3x + 9y = 75
b) 8x + 5y = 67
Substitution:
a) 3x = -9y + 75
x = (-9y + 75)/3
x = -3y + 25
Substitute:
b) 8(-3y+25) + 5y = 67
-24y + 209 + 5y = 67
-19y = -209 +67
y = -133/-19
y = 7
Substitute:
x = = 3(7) + 25
x = -21+25
x = 4

How many solutions can be found for the system of linear equations represented
on the graph?
A) no solution
3) one solution
D) infinitely many solutions
C) two solutions
Answer:
Infinitely Many Solutions
Step-by-step explanation:
They are the same line so they cross each other infinitely many times.
If you picked a point on the first equation it would be the same point on the second equation.
Answer:
D) Infinitely many solutions
Step-by-step explanation:
Given the follwowing systems of linear equations, y = x + 2, and -3x + 3y = 6:
Transforming -3x + 3y = 6 into its slope-intercept form, y = mx + b:
-3x + 3y = 6
Add 3x to both sides:
-3x + 3x + 3y = 3x + 6
3y = 3x + 6
Divide both sides by 3:
[tex]\frac{3y}{3} = \frac{3x + 6}{3}[/tex]
y = x + 2 ⇒ This is the slope-intercept form of -3x + 3y = 6. Since they are equivalent equations, then it means that their graphed lines coincide. Since any point on either lines coincide (or also exists) on the other line, then it means that the solutions to one of the equations will satisfy the other. Therefore, the given systems of linear equations have an infinitely many solutions.

Answer:
m=2
Step-by-step explanation:
you subtract the y-values (4-2) and put it as the numerator of a fraction than subtract the x-values (3-2) and put them as the denominator of the fraction. For this equation it would be
[tex]\frac{4-2}{3-2} = \frac{2}{1} = 2[/tex]
Suppose the matrix R represents a railroad map between cities 1, 2, 3, 4, and 5.
How many different ways can you travel from city 1 to city 3 with exactly 1 connection
How many different ways can you travel from city 2 to city 5 with exactly one
connection?
Observing the given matrix we can say that:
1) The value is 4.
2) The value is 2.
So analyzing the different paths that can connect city 1 to city 3: The value is 4. It represents the number of one-stop routes between City 1 and City 3 that pass through City 2.
For the second statement we will have the value is 2. It is the number of direct routes from City 2 to City 5.

Answer:
√73 mi√134 ft.......................Find the measures of the interior angles.
what is angle B and C?
Answer:
x = 42
Step-by-step explanation:
The square at ∠C means it is a right angle (90°). The sum of the angles of a triangle is 180°. Use the information to solve for ∠B.
[tex]x+48+90=180\\x+138=180\\x=42[/tex]
Answer:
B = 41 degreed
Step-by-step explanation:
Square of C = 90degrees
A = 49degrees
90 + 49 = 139degrees
180degrees - 139degrees = 41 degrees

5√8 = 14.1
√170 = 13.03
5/8 = 0.625
0.62 = 0.62
Answer:
5sqrt(8), sqrt(170), 5/8, 0.62
Step-by-step explanation:
Solve any equations and put them in decimal form to make it easier to list them from biggest to smallest.
Ex: sqrt(170) = 13.04
5sqrt(8) = 14.14

p= 7000
r= 2.45%
t= 7 years
Answer:
1200.5
Step-by-step explanation:
Interest Rate = (Simple Interest × 100)/(Principal × Time).
I= 7000(.0245)(7)
I=1200.5
Answer:
1,200.5
Step-by-step explanation:
Simple interest is
I = Prt,
where I is the interest earn after t years, P is the initial money , r is the rate
I = 7000*.0245*7 = 1,200.5
1,200.5 is the interest after 7 years

what is the sum of two arithmetic means between 6 and 2
pls show solutions guys!!
Answer:
8Step-by-step explanation:
Let the numbers are:
6, x, y, 2Since the sequence is arithmetic, the difference of two consecutive terms is same:
d = x - 6 = y - x = 2 - yTherefore:
x = 6 + dy = 6 + 2d2 = 6 + 3dThe sum of the first two equations:
x + y = 6 + d + 6 + 2d = 6 + (6 + 3d)Substitute (6 + 3d) with 2 (the third equation) to get:
x + y = 6 + 2 = 8What is 1/3 by the power of 4 in the simplest form. No links.
(1/3)^4 = 1^4/ 3^4 = 1/81
Answer: 1/81
The expression 1/3 by the power of 4 when evaluated has a value of 1/81
How to evaluate the expressionFrom the question, we have the following parameters that can be used in our computation:
1/3 by the power of 4
Express as an equation
So, we have
1/3 by the power of 4 = 1/3⁴
When expanded, we have
1/3 by the power of 4 = 1/3 * 1/3 * 1/3 * 1/3
Evaluate the products
This gives
1/3 by the power of 4 = 1/81
Hence, the solution is 1/81

Find the value of K so that line passing through the points (k,-1) and (-2,8) is parallel to the equation 3x+y=-7
Answer:
k =1
Step-by-step explanation:
3x + y = -7
y = -3x - 7
m = -3
Parallel lines have same slope
[tex]Slope = -3\\\\\dfrac{8-[-1]}{-2-k}=-3\\\\\\\dfrac{8+1}{-2-k}=-3\\\\\dfrac{9}{-2-k} = -3[/tex]
Cross multiply,

9 = 6 + 3k
9-6 = 3k
3 = 3k

Answer:
y = - [tex]\frac{4}{3}[/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 )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (3, - 2) ← 2 points on the line
m = [tex]\frac{-2-2}{3-0}[/tex] = [tex]\frac{-4}{3}[/tex] = - [tex]\frac{4}{3}[/tex]
The line crosses the y- axis at (0, 2 ) ⇒ c = 2
y = - [tex]\frac{4}{3}[/tex] x + 2 ← equation of line
