Answer:
∠ACB = 72
Step-by-step explanation:
OAD is straight line.
∠DAB + ∠OAB = 180
142 + ∠OAB = 180
∠OAB = 180 - 142
∠OAB = 38
ΔAOB is isosceles triangle. OA = OB = radius
∠OAB = ∠OBA = 38 {angles opposite to equal sides or equal}
In ΔAOB ,
∠OAB + ∠OBA + ∠AOB = 180 {Anlge sum property of triangle}
38 + 38 + ∠AOB = 180
76 + ∠AOB = 180
∠AOB = 180 - 76
∠AOB = 104
THe angle subtended by an arc of a circle at the center is double the angle subtended by it at any point on the remaining part of the circle
∠AOB = 2*∠ACB
∠ACB = ∠AOB/2
= 104/2
∠ACB = 72
Given h(x) = 4x – 5, solve for x when h(x) = 7.
Answer: x = 3 when h(x) = 7.
Step-by-step explanation:
h(x) = 4x -5 To solve for x when h(x) = 7, you will set the expression 4x -5 equals 7 to solve for x.
4x -5 = 7 Add 5 to both sides
+5 +5
4x = 12 Divide both sides by 4.
x= 3

Katie empties her purse and finds that it contains only nickels (worth 5 cents each) and dimes (worth 10
cents each). If she has a total of 7 coins and they have a combined value of 45 cents, how many of each coin
does she have?
Answer:
Step-by-step explanation:
2 dimes and 5 nickels
Dimes: 10 × 2 = 20
Nickels: 5 × 5 = 25
Answer:
5 nickel and two dimes
Step-by-step explanation:
let let X be the number of Nickels
number of X is equals to 7 - x
5x+ 10*(7-x)= 45
X= 5
thus nickel is 5 and dimes is 2

The table below represents a linear function f(x) and the equation represents a function g(x):
Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)
Part B: Which function has a greater y-intercept? Justify your answer. (4 points)
Answer:
Slope of f(x) is greater than slope of g(x)
g(x) has a greater y intercept
Step-by-step explanation:
Given
f(x) table
[tex]g(x) = 2x + 6[/tex]
Solving (a):
First, we determine the slope of f(x).
From the table, we take any two corresponding values of x and f(x).
Represent f(x) with y
[tex](x_1,y_1) = (-1.-12)[/tex]
[tex](x_2,y_2) = (0.-6)[/tex]
The slope (m) is calculated as thus
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{-6 - (-12)}{0 - (-1)}[/tex]
[tex]m = \frac{-6 +12}{0 +1}[/tex]
[tex]m = \frac{6}{1}[/tex]
[tex]m = 6[/tex]
Represent this with m1
[tex]m_1 = 6[/tex]
Calculating the slope of g(x).
The general form of an equation is [tex]y = mx + b[/tex]
Where m represents the slope.
We have that:
[tex]g(x) = 2x + 6[/tex]
By comparing [tex]g(x) = 2x + 6[/tex] with [tex]y = mx + b[/tex]
[tex]m = 2[/tex]
Represent this with m2
[tex]m_2 = 2[/tex]
Comparing both slope, we can say that:
f(x) has a greater than slope of g(x)
Another comparison is that:
Slope of f(x) is 3 times the slope of g(x)
Solving (b): Function with greater y intercept.
The general form of an equation is [tex]y = mx + b[/tex]
Where b represents the y intercept.
First, we need to determine the equation of f(x) using:
[tex]y - y_1 = m(x - x_1)[/tex]
Recall that, from the table of f(x):
[tex](x_1,y_1) = (-1.-12)[/tex]
[tex](x_2,y_2) = (0.-6)[/tex]
[tex]m_1 = 6[/tex]
So:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - (-12) = 6(x - (-1))[/tex]
[tex]y + 12 = 6(x +1)[/tex]
[tex]y + 12 = 6x +6[/tex]
Solve for y
[tex]y = 6x + 6 - 12[/tex]
[tex]y = 6x - 6[/tex]
By comparing this with [tex]y = mx + b[/tex], the y intercept of f(x) is -6
For g(x), we have:
[tex]g(x) = 2x + 6[/tex]
By comparing this with [tex]y = mx + b[/tex], the y intercept of g(x) is 6
Comparing the y intercepts of both functions, g(x) has a greater y intercept because [tex]6 > -6[/tex]

solve for x 2(3x-2)-4x+1=9 linear equations with disbribution
Answer:
x=-2/3,2
Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
2 (3x - 2) - 4x + 1 = 9
Distribute the 2 to 3x and -2
6x - 4 - 4x + 1 = 9
Combine like terms
2x - 3 = 9
Add three to both sides
2x = 12
Divide by 2
x = 6

What is f(x)= 3x+ 13(17x-7) if x equals 4?
Answer:
805
Given:
x=4
Step-by-step explanation:
f(x) = 3x + 13(17x-7)
f(x) = 3 × 4 + 13(17 × 4 - 7)
f(x) = 12 + 13(68 - 7)
f(x) = 12 + 13 × 68 - 13 × 7
f(x) = 12 + 884 - 91
f(x) = 12 + 793
f(x) = 805
