What are the values of x, y, and z?
help asap
Answer:
x = 111; y =36; z = 76
Step-by-step explanation:
The sum of the interior angles of a triangle will add up to zero and a line that divides a straight line into to parts will have a sum of angles of 180 degrees. Use this information to add and subtract the angles to find x, y, and z.

Answer:
m∠A = 45⁰
m∠B = 75⁰
Step-by-step explanation:
Given question 4;
m∠A = x + 51
m∠B = 81 + x
m∠C = 60⁰
The value of the missing angles can be determined by the finding the value of x first;
m∠A + m∠B + m∠C = 180⁰ (sum of angles in a triangle)
(x + 51) + (81 + x) + 60⁰ = 180
(x + x) + (51 + 81 + 60) = 180
2x + 192 = 180
2x = 180 - 192
2x = -12
x = -12/2
x = -6
Thus, the values of the angles are calculated as follows;
m∠A = x + 51
= -6 + 51
= 45⁰
m∠B = 81 + x
= 81 - 6
= 75⁰
I need help with this equation for math
Answer:
The answer would be B
Step-by-step explanation:
the y-intercept would be a postive 4 and because it's a negative slope, it would rule out all of them except B.
Answer:
y = -1/2x +4
Step-by-step explanation:
We have two points so we can find the slope
m = (y2-y1)/(x2-x1)
= ( 0-4)/(8-0)
= -4/8
= -1/2
We know the y intercept is 4
The slope intercept form of the line is
y = mx+b where m is the slope and b is the y intercept
y = -1/2x +4

Find the value of x.
A 2
B 4.8
C 6
D 6.4
Answer:
D
Step-by-step explanation:
Δ DCA and Δ ABE are similar, thus the ratios of corresponding sides are equal, that is
[tex]\frac{CA}{BE}[/tex] = [tex]\frac{DA}{AE}[/tex] , substitute values
[tex]\frac{18}{10}[/tex] = [tex]\frac{x+8}{8}[/tex] ( cross- multiply )
10(x + 8) = 144 ( divide both sides by 10 )
x + 8 = 14.4 ( subtract 8 from both sides )
x = 6.4 → D
The value of x is the length of BD, so x = 6.So, The correct answer is C. 6.
The value of x is the length of the altitude from vertex B to side AC. We can find this length by using the Pythagorean Theorem on right triangle ABD.
[tex]AB^2 + BD^2 = AD^2\\8^2 + BD^2 = 10^2\\BD^2 = 36\\BD = 6[/tex]
The altitude from vertex B to side AC is equal to the length of BD, so x = 6.
Here is a breakdown of the steps involved in solving for x:
We are given the lengths of sides AB and AC of triangle ABC.
We know that the altitude from vertex B to side AC will be perpendicular to side AC. We can use the Pythagorean Theorem on right triangle ABD to find the length of BD, which is the altitude from vertex B to side AC.

Answer:
Your answer would be -2/5
Step-by-step explanation:
The value of the given expression is -2/5.
The given expression is [tex]\sqrt[3]{-\frac{8}{125} }[/tex].
How to solve cube roots?In mathematics, the definition of cube root is written as Cube root is the number that needs to be multiplied three times to get the original number. Now, let us look at the cube root formula, where y is the cube root of x. ∛x = y.
Now, [tex]\sqrt[3]{-\frac{8}{125} }[/tex] can be written as [tex]\sqrt[3]{(-\frac{2}{5})^{3} }[/tex].

the graph of g(x) =x -5 is a translation of the graph of the parent function 5 units
Answer:
the answer is: 8(x)= 4 -5
Step-by-step explanation:
The graph of parent function and translated function are given below. Therefore, the transformation is shifted down 5 units.
The given function is g(x)=x-5.
What is the translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.
Here, parent function is g(x) = x
To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
Shifted down: 5 units
The graph of parent function and translated function are given below. Therefore, the transformation is shifted down 5 units.

Answer:
Step 1 and step 2
Step-by-step explanation:
she has to subtract 30 not add 30.
2(3x+6)=3(x-10)
6x + 12 = 3x-30
6x +12 - 12 = 3x - 30 - 12
6x = 3x - 42
6x - 3x = 3x - 42 - 3x
3x = -42
3x/3 = -42/3
x = -14
Answer:
B
Step-by-step explanation:
Hey There!
So the first thing we're going to do is solve it and then compare it to Maya's steps to see where she made the mistake
2(3x+6)=3(x-10)
step 1 distribute the 2 to whats inside of the parenthesis (3x+6)
2*3x=6x
2*6=12
now we have
6x+12=3(x-10)
step 2 distribute 3 to what's inside of the parenthesis
3*x=3x
3*-10=-30
we're left with
6x+12=3x-30
step 3 add 30 to each side
12+30=42
now we have
6x+42=3x
step 4 subtract 6x from each side
3x-6x=-3x
now we have
-3x=42
step 5 divide each side by -3
42/-3=-14
so x = -14
now lets compare our steps to maya's
as we look at the steps we notice that she messes up on step 2
when distributing 3 to -10
she gets positive 30 but its supposed to be -30
so we can conclude that she mad a mistake from step 1 to step 2
therefore the second one is your answer

is -6/3 and integer? dont guess ;( helppp
Answer:
no because
Fractions and decimals are not integers. All whole numbers are integers (and all natural numbers are integers), but not all integers are whole numbers or natural numbers. For example, -5 is an integer but not a whole number or a natural number.
-6/3 is not an integer.

What is the slope of a line that is perpendicular to the line that passes through the points (9,0) and (3,7)?
Answer:
6/7
Step-by-step explanation:
Product of slope of perpendicular line = -1
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]= \frac{7-0}{3-9}\\\\=\frac{7}{-6}\\\\=\frac{-7}{6}[/tex]
Slope of the perpendicular line = -1/m = -1 ÷ [tex]\frac{-7}{6}[/tex]
[tex]= -1 * \frac{-6}{7} = \frac{6}{7}[/tex]
A fountain holds 12500 7/8 gallons of water. Joe wants to calculate how many liters that is. Which proportion could he use to solve for the number of liters? (1 gal = 3.79 L)
Answer:
47378.31625 Liters
Step-by-step explanation:
A fountain holds 12500 7/8 gallons of water. Joe wants to calculate how many liters that is. Which proportion could he use to solve for the number of liters? (1 gal = 3.79 L)
From the above question,
1 gallon = 3.79 Liters
12500 7/8 gallons = x Liters
Cross Multiply
x Liters = 12500 7/8 × 3.79 Liters
x = 47378.31625 Liters
Therefore, the number of liters of water in the fountain is 47378.31625 Liters
