I need to find the missing angle measures.
Answer:
step 1. b = 102° (vertical angles)
step 2. one complete revolution equals 360°
step 3. a + b + c + 102 = 360
step 4. a + 102 + c + 102 = 360
step 5. a + c = 156°
step 6. 2a = 156 (vertical angles are equal)
step 7. a = 78°, c = 78°.

3x^2-8x+4=0 Solve quadratic equations by completing the square.
Answer:
x = ⅔ Or x = 2Explanation:
3x² − 8x + 4 = 0
Factor left side of equation
(3x − 2)(x − 2) = 0
Set factors equal to 0
3x − 2 = 0 or x − 2 = 0
x = ⅔ or x = 2Quadratic equations are a form of algebraic equations that can or cannot be factorized.
The value of x is 2 and 2/3
Quadratic equations come in the form: ax²+ bx + c = 0
Solution by completing the square for:
3x²− 8x + 4 = 0
a = 3 , a≠1 so we divide through by 3
3x²/3 − 8x/3 +4/3 = 0/3
which gives us
x²− 8x/3 + 4/3 = 0
Subtract 4/3 from both sides
x²− 8x/3 + 4/3 - 4/3 = 0 - 4/3
x² − 8x/3 = −4/3
Take half of the x term and square it and add the result to both sides
x² − 8x/3 + 16/9 = −4/3 + 16/9
Rewrite the perfect square on the left
(x − 4/3)² = −4/3 + 16/9
and combine terms on the right
(x − 4/3)²= 4/9
Take the square root of both sides
x − 4/3 = ±√4/9
Simplify
x − 4/3 = ±2/3
Collect like terms
x = 4/3 ± 2/3
Solving for xx = 4/3 + 2/3
x = 6/3
x = 2
Also:
x=4/3 − 2/3
which becomes
x = 2/3

How to find the slope of (0,7) and (5,9)?
Answer:
The slope is 2/5 (0.4).
Step-by-step explanation:
The formula for finding a slope is m = (yB - yA)/(xB - xA). That equation becomes:
m = (9 - 7)/(5 - 0)
Subtract 7 from 9 to get 2.
m = 2/(5 - 0)
Any number subtracted by 0 equals itself.
m = 2/5, or 0.4 is the final answer.

Solve the system by substitution:
3x + 2y = 26
Y=x + 3
Answer:
x = 4
Step-by-step explanation:
3x + 2y = 26
y = x + 3
Plug in the equation for y
3x + 2(x + 3) = 26
Multiply the 2 with what is in the parantheses
3x + 2x + 6 = 26
Combine like terms and solve for x
5x + 6 = 26
5x = 20
x = 4
Answer
x=4, Y=7
Step-by-step explanation:
3x + 2y = 26
Y=x + 3
3x+2(x+3)=26
3x+2x+6=26
5x=20
x=4
Y=4+3
Y=7
Check
3(4)+2(7)=26
12+14=26

Create two expressions equivalent to 48j + 36 using the expresion below:
6(_ j + _ )
Answer:
Two expressions equivalent to 48j + 36.
Use distributive property of multiplication.
Since 6 is the factor, divide each term by 6 to get the other factor;
48j + 36 = 6*8j + 6*6 = 6*(8j + 6) =6*2(4j + 3)60 people were asked the colour of their car and the pictogram shows the results.
a) 16 cars are red. Complete the key.
b) How many cars are silver?
KEY: One circle represents __ cars
Red = 4 circles
White = 3 circles and a half
Silver = 5 circles and 3/4
Grey = 1 circle and 3/4
The number of silver cars in the pictogram is 23.
How many cars are silver?If 16 cars are red, then, each circle represents 4 cars.
If each circle represents 4 cars, then, each quarter of a circle represents 1 car
White car = 4 + 4 + 4 + 2
= 14 cars
Silver = 4 + 4 + 4 + 4 + 4 + 3
= 23 cars
Grey = 4 + 3
= 7 cars
Total cars = red + white + silver + grey
= 16 + 14 + 23 + 7
= 60 cars
It can therefore be concluded that silver cars is 23 in number.

Akira is folding a piece of paper that is 0.2 millimeters thick in half. The thickness of the paper doubles with each fold. Let n represent the fold number and t(n) represent the thickness of the paper. Which exponential function represents this scenario?
Answer:
t(n)= 0.2 * 2ⁿ
Step-by-step explanation:
Thickness= 0.2 millimeters
paper = 1
n= number of folds
The exponential function will be given by
t(n)= 0.2 * 2ⁿ
so if there's a single fold
t(1)= 0.2 * 2¹
t(1)= 0.4 mm
Now for 2 folds the thickness will be
t(2) = 0.2 *2 ²
t(2)= 0.2 *4
t(2) = 0.8mm
The exponential that represents this scenario is
t(n)= 0.2 * 2ⁿ
And for 3 folds the thickness will be
t(3) = 0.2 *2 ³
t(3)= 0.2 *8
t(3) = 1.6 mm
