What is the measure of Zy?
139 yº
Answer:
y = 41°
Step-by-step explanation:
∡ y and 139° are adjacent angles and sum to 180° , that is
∠ 1 + 139° = 180° ( subtract 139° from both sides )
∠ 1 = 41°
Solve the equation for y. Then find the value of y for each value of x.
y + 5x = 8; x = - 2, 0,3
Solve the equation for y.
Answer:
y = 8 - 5x, y(-2) = 18, y(0) = 8, y(3) = -7
Step-by-step explanation:
y + 5x = 8
y = 8 - 5x
y(-2) = 8 - 5*(-2) = 8 + 10 = 18
y(0) = 8 - 5*(0) = 8 - 0 = 8
y(3) = 8 - 5*(3) = 8 - 15 = -7

What is the average rate of change for this quadratic function for the interval from x = 0 to x = 2?
A. 4
B. 2
C. -4
D. -2
Answer:
Option B
Step-by-step explanation:
Average rate of change of a function between x = a and x = b will be,
Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
We have to calculate average rate of change of the given quadratic function between x = 0 and x = 2.
From the given graph,
f(2) = 6
f(0) = 10
Therefore, average rate of change = [tex]\frac{f(2)-f(0)}{2-0}[/tex]
= [tex]\frac{10-6}{2-0}[/tex]
= 2
Option B will be the answer.
I’m failing and areas aren’t my best subject, please help!
Work out the surface area of this solid prism
Answer:
3220 cm²
Step-by-step explanation:
Lets find the area of the two triangles
I am making a modification:
Both of the triangles are the same, so I wont divide by 2 using the area of triangle formula 1/2(b * h) because we end up multiply by 2
Area of triangles = 15 cm x 28 cm = 420 cm²
Area of front facing parallelogram = 24 cm x 4(10)cm = 100(10)cm = 1000 cm²
Area of back facing parallelogram = 17 cm x 40 cm = 680 cm²
Area of bottom parallelogram = 40 cm x 28 cm = 1120 cm²
Total Surface area = 420 cm² + 1000 cm² + 680 cm² + 1120 cm² = 1100 cm² + 2120 cm² = 3220 cm²
If my answer is incorrect, pls correct me!

Solve for x. Answer as a whole number.
Given:
In triangle ABC, AE is the angle bisector.
[tex]AB=4, BE=2, AC=x, CE=3[/tex]
To find:
The value of x.
Solution:
According to the angle bisector theorem, the angle bisector of a triangle divides the opposite side of the triangle into two parts. These two parts are proportional to the other two sides of the triangle.
Using the angle bisector theorem, we get
[tex]\dfrac{AB}{AC}=\dfrac{BE}{CE}[/tex]
[tex]\dfrac{4}{x}=\dfrac{2}{3}[/tex]
On cross multiplication, we get
[tex]4\times 3=2\times x[/tex]
[tex]12=2x[/tex]
Divide both sides by 2.
[tex]\dfrac{12}{2}=x[/tex]
[tex]6=x[/tex]
Therefore, the value of x is 6.
*7. Admission to a museum is $8.20 per adult and $4.10 per child. The expression
8.2a + 4.1c represents the total cost in dollars for admission for a adults and a
children
A group of friends, consisting of 6 adults and 6 children attend the museum. One of
the adults has a coupon for one free adult admission and one child's admission at half
price. What is the total cost for the whole group to enter the museum?
Answer:
$63.55
Step-by-step explanation:
if one of the adults has a free coupon for adult admission, then we have 5 adults
8.20 x 5 = $41
We have 6 children and one with half pay
= (5 x 4.1) + (4.1/2 )
= 20.5 + 2.05
=$22.55
41 + 22.55 = $63.55
Find the circumference of the circle to the nearest hundredth
11cm
Question: Find the circumference of the circle to the nearest hundredth
d = 11cm
Answer:
34.54 cm
Step-by-step explanation:
Applying,
P = πd...................... Equation 1
Where P = Circumference of perimeter of the circle, d = diameter of the circle, π = pie
From the question
Given: d = 11 cm
Constant: π = 3.14
Substitute these values into equation 1
P = (3.14×11)
P = 34.54 cm
a. Find the mean, median, and mode of 12, 9, 17, 15, 10.
mean:
median:
6
Answer:
Mean: 12.6
Median: 12
Mode: None
Step-by-step explanation:
To find the mode, add everything up.
12 + 9 + 17 +15 + 10 = 63. Then, divide by five.
63 ÷ 5 = 12.6
To find the median, put the numbers from least to greatest. Then, highlight the one in the middle.
9, 10, 12, 15, 17
To find the mode, look for the number that appears the most. Because each number appears once. So, put "none" in the box.
Have a wonderful day!

Convert the following equation into slope intercept form y-6=2(x+4)
Answer:
y = 2x +14
Step-by-step explanation:
We need to convert the given equation into slope intercept form ,
=> y - 6 = 2(x+4)
=> y -6= 2x + 8
=> y = 2x +8+6
=> y = 2x + 14
• Hence the required answer is y = 2x + 14Sam is 10 years younger than one-half the age of his aunt. Let a represent his aunt’s age. Which algebraic expression can be used to determine Sam’s age if his aunt is 40?

Solve |3x - 4| = 6
please help me solve
Step-by-step explanation:
|3x - 4| = 6
3x-4 = 6 or 3x-4 = -6
3x=6+4 3x=-6+4
3x=10 3x = -2
x= 10/3 x = -2/3
so, x1= 10/3 or x2 = -2/3
