Answer:
area = 84 cm²
Step-by-step explanation:
the quadrilateral is made up of 2 triangles ABD and BDC
area of Δ ABD = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
A = [tex]\frac{1}{2}[/tex] × BD × AE = [tex]\frac{1}{2}[/tex] × 14 × 7 = 7 × 7 = 49 cm²
area of Δ BDC = [tex]\frac{1}{2}[/tex] × BD × CF = [tex]\frac{1}{2}[/tex] × 14 × 5 = 7 × 5 = 35 cm²
area of ABCD = 49 + 35 = 84 cm²

is the equation y + 1 equals 8 (x + 6) in point-slope form?
Answer:
Yes
Step-by-step explanation:
The equation is y-y1=m(x-x1)
Answer: Yes
Step-by-step explanation:
The formula for point-slope form is y-1₁=m(x-x₁). The given equation is y+1=8(x+6). That means the given point is (-6,-1), and the slope is 8.

The arrow on the graph points right.
Answer:
X Greater-than-or-equal-to 12 A closed circle is used on the graph. The arrow on the graph points right.Step-by-step explanation:
This one-step inequality can be solved by adding the opposite of the constant that is added to x. A number line graph of the solution is attached.
x -2.6 ≥ 9.4
x ≥ 12.0 . . . . . . add 2.6 to both sides
The "greater than" relation means that numbers larger than 12 will be included in the solution set. Shading of the number line will be to the right of 12.
The "or equal to" relation means that 12 itself is included in the solution set. This is indicated by a closed circle at 12 on the graph.
The true statements are ...

Step-by-step explanation:
You are adding orange juice to a 10-liter capacity jar. The equation 3x – 2y = -5 relates the amount of juice y, in liters, with the number of minutes, x, you add juice. How much juice was in the jar to start?
At what rate is the jar filled?
Answer: 5/2 liters (or 2.5 liters) of juice were in the jar to start.
The jar was filled at a rate of 5 minutes.
Step-by-step explanation: Firstly, rearrange the equation so that y = mx + b. If you move the x over, you get -2y = -3x -5. To get rid of the -2 in front of the y, divide both sides by -2. Then you get y = 3/2x + 5/2.
The amount of juice in the jar initially is b, also known as the y-intercept.
If you look at the equation, you see that 5/2 is our y-intercept which means the jar initially had 5/2 liters of juice at the start (this is the same as 2.5 liters because 5 divided by 2 is 2.5).
To find the rate at which the jar was filled, you need to solve for x. Plug in the 10 liters for the y and solve.
y = 3/2x + 5/2
10 = 3/2x + 5/2
Now, subtract 5/2 from both sides.
7.5 = 3/2x
Divided both sides by 3/2 to get x alone, which will give you the number of minutes in which the jar was filled.
5 = x
The jar was filled at a rate of 5 minutes.

Mrs. Lovejoy makes flower arrangements. She has 36 red carnations, 60 white carnations, and 72 pink carnations. Each arrangement must have the same number of each color. What is the greatest number of arrangements she can make if she uses every carnation?
Answer:
12 arrangements
Step-by-step explanation:
We solve this question using the Greatest Common Factor method.
We are told that:
She has 36 red carnations, 60 white carnations, and 72 pink carnations.
The same number of each item should be in each basket.
The greatest number of baskets is calculated as follows:
Step 1
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
Step 2
We Identify the number that is greatest and common amongst 36,60, and 72
This is 12.
Then the greatest common factor is 12
Therefore, the greatest number of arrangements she can make if she uses every carnation is 12 arrangements

A music producer is making a list of vocalists needed to record an album. For each day of recording, a different number of vocalists are needed. The first day, six vocalists are needed. Each day after that, the number of vocalists needed doubles. The producer must pay by the day for each vocalist. To find the total price, the producer needs to know how many vocalists sang in total at the end of the 10th day. Use a series to find the sum after the 10th day. 114 150 3,066 6,138
Answer:
6,138
Step-by-step explanation:
Given the following:
Vocalist needed :
First day (a) = 6
For subsequent days : number doubles
Using the relation. :
Sn = a(r^n -1)/(r -1)
Where a = first term = 6
r = common ratio = r3/r2 = r4/r3
Since number doubles after each consecutive day, then ; r = 2, n = 10
Sn = 6(2^10 -1)/(2 -1)
Sn = 6(1024 - 1) / 1
Sn = 6144 - 6
Sn = 6138
What are coordinates of points A, B, C, and D?
Answer:
See below.
Step-by-step explanation:
A = (-2/3, 0)
B = (-1/6, 0)
C = (1/2, 0)
D = (4/3, 0)
Step-by-step explanation:
the interval between 0 and 1 shows us, that on that scale the distance between 2 full numbers is split into 6 parts.
so, every little marker represents 1/6.
A goes 4 markers below 0 (left of 0) and is -4/6 = -2/3.
B goes 1 marker below 0 and is -1/6.
C goes 3 markers above 0 (right of 0) and is 3/6 = 1/2.
D goes 2 markers above 1 and is
1 + 2/6 = 6/6 + 2/6 = 8/6 = 4/3 = 1 1/3
please pick the format your teacher wants you to use to write the result.
if you actually need decimals instead of fractions :
-2/3 = -0.666666666...
-1/6 = -0.166666666...
1/2 = 0.5
4/3 = 1.333333333...
