Answer:
x=80deg, y=40deg
Step-by-step explanation:
Note that both triangles are isosceles triangles.
That means the right one has 2 angles y and 1 angle 100deg.
The sum is 180deg, so
180deg = 2 * y + 100deg
2y = 180deg - 100deg = 80deg
y = 40deg
The left one has one angle x and 2 angles of 50deg.
180deg = x + 2 * 50deg = x + 100deg
x = 180deg - 100deg
x = 80deg
Answer:
x = 80, y = 40
Step-by-step explanation:
Both triangles are isosceles, 2 congruent sides, so the base angles are congruent.
Triangle on left
base angles are congruent and equal to 50° , then
x = 180° - (50 + 50)° ← sum of angles in triangle = 180°
x = 180° - 100° = 80°
Triangle on right
base angles are congruent and equal to y , then
y = [tex]\frac{180-100}{2}[/tex] = [tex]\frac{80}{2}[/tex] = 40°

Answers
Answer:
x = 9
Step-by-step explanation:
Given
2(x + 5) = 3x + 1 ← distribute left side
2x + 10 = 3x + 1 ( subtract 2x from both sides )
10 = x + 1 ( subtract 1 from both sides )
9 = x

Rate of change is another way to say slope. To find the slope of a line, use this formula:
m = (y2-y1)/(x2-x1) where m is the slope, and (x1, y1) and (x2, y2).
To find the slope of the function in the table, take two coordinates (I’ll use (-1, 5) and (1,9)) and plug them into the slope formula.
m = (9-5)/(1+1) = 4/2 = 2
The slope/rate of change equals 2. The only equation in the answer choices where the slope is 2 is A, so A is the answer

Simplify this expression. 2 square root 5 (13 + square root 2)
Answers
Answer:
i'm assuming it's 2*√5(13+√2) so 2√10+26√5
Step-by-step explanation:
The product of 2 square root 5 (13 + square root 2) in simplified form is 26√5 + 2√10
Calculating the product in simplified formFrom the question, we have the following parameters that can be used in our computation:
2 square root 5 (13 + square root 2)
Express as products
So, we have
2√5 * (13 + √2)
Open the brackets
So, we have
2√5 * (13 + √2) = 2√5 * 13 + 2√5 *√2
Multiply the radicands
So, we have the following
2√5 * (13 + √2) = 2√5 * 13 + 2√10
Evaluate the products
So, we have the following
2√5 * (13 + √2) = 26√5 + 2√10
Hence, the solution is 26√5 + 2√10

A TV that usually sells for $170.09 is on sale for 15% off. If sales tax on the TV is 6%, what is the price of the TV, including tax?
Answers
A TV that usually sells for $170.09 is on sale for 15% off. If sales tax on the TV is 6%, what is the price of the TV, including tax?
Find the discounted price: 15% off of 170.09
Discounted Price = 170.09 * (1 - 0.15) <-- 15% as a decimal is 0.15, and 1 is 100%. So, we subtract to get 85% of the original price.
Discounted Price =170.09(0.85)
Discounted Price = $144
Now, add in the sales tax of 6% to the Discounted Price.
Price after sales tax = Discounted Price * 1.06
Price after sales tax = $144 * 1.06
Price after sales tax = $152.64

Answer:
(-9, 5)
Step-by-step explanation:
there are 2 variable: x and y
eliminate one of the variables for example y
-x - y = 4
-2x - y = 13 multiply this equation by (-1)
-x - y = 4
2x + y = -13
add both equations
2x-x-y+y = 4-13
x = -9
substitute x = -9 in the first equation
-(-9)-y = 4
9 - y = 4 subtract 9 from both sides
-y = 4 - 9
-y = -5 multiply by (-1)
y = 5
