Calculate the area of triangle ABC with altitude CD, given A(−7, −1), B(−1, 5), C(0, 0), and D(−3, 3). 9 square units 18 square units 18.5 square units 21 square units
9514 1404 393
Answer:
18 square units
Step-by-step explanation:
Referring to the figure, we see that the base AB has a slope of 1, and the altitude CD has a slope of -1. The number of unit squares crossed by these segments are, respectively 6 and 3, so the length of each is ...
AB = 6√2
CD =3√2
The area is half the product of the base (AB) and height (CD) so is ...
A = 1/2bh = (1/2)(6√2)(3√2) = 18
The area of ΔABC is 18 square units.

Additional comment
It is useful to remember that the diagonal of a unit square is √2. We used that fact here. If you need to figure it using the Pythagorean theorem, you find ...
c² = a² +b²
c = 1² +1² = 2
c = √2

A recipe uses 5 cups of milk to make 30 servings. If the same amount of milk is used for each serving, how many servings can be made from one quart?
1 gallon = 4 quarts, 1 quart = 2 pints, 1 pint = 2 cups, 1 cup = 8 fluid ounces
Before you try that problem, answer the question below.
How many cups will you need to find the number of servings for?
Answer:
is 6 a choice if so that is the correct answer:)
Step-by-step explanation:
bc ik
Answer:
For the first part the answer is we will to find the number of servings for 8 cups.
The second and finnal answer is 16 servings
Step-by-step explanation:
2 quarts x 2 = 4 pints x 2 = 8 cups
5 cups per 10 servings unit rate is 1:2 X 8 = 8:16, Therfore 16 servings.

Answer:
x = -5 y = -3
Step-by-step explanation:
-3x + 2y = 9
multiply the 2nd equation by 3 to set it up for elimination
3(x - 3y)= 3(4)
3x-9y = 12
so now combine both to add
-3x + 2y = 9
3x - 9y = 12
Adding both gives you
-7y = 21
divide both by -7 and you get
y = -3
and you substitute y back into equation to get x
x - 3 (-3) = 4 gives you
x + 9 = 4
x = 4 - 9
x = -5

A student committee is organizing a school dance as a fundraiser. The function f ( x ) = 5 x − 320 represents the total amount of funds raised based on the number of tickets sold, x , minus the cost of decorations
I assume you want this explained
Answer and explanation:
If the function f ( x ) = 5 x − 320 represents the total amount of funds raised based on the number of tickets sold, x , minus the cost of decorations then x number of tickets is an independent variable here that will determine the total amount of funds raised y(dependent variable)
The y intercept is -320 and the slope is 5
If for example the number of tickets sold = 100 tickets
Total amount of funds using the function :
f(100)= 5×100-320
=500-320
= $180
Answer:
The slope of the function is 5, and it represents the price of each ticket .

A. x=0
B. x= 1
C. there are infinitely many solutions.
D. There is no solution.
Brian chose D as the correct answer. How did he get that answer?
Answer:
X=0
Step-by-step explanation:
3x-12=2x-12
3x-2x= -12+12
x=0

What’s the answer
Answer:
n=15
Step-by-step explanation:
300/20=15
n=15
Answer:
n = 15
Step-by-step explanation:
I took 300 and divided it by 20 to find n.
300 / 20 = 15
To check the answer, I completed this;
20(15) = 300
300 = 300

Is x = 6 a solution to the equation x + 13 = 18?
O A. Yes, because 6 +13 = 18 is true.
O B. No, because 6 + 13 = 18 is true.
C. No, because 6 + 13 = 18 is not true.
D. Yes, because 6 + 13 = 18 is not true.
x = 6 is not a solution to the equation x + 13 = 18.
Hence, Option C) No, because 6 + 13 = 18 is not true. is the correct answer.
Is x = 6 a solution to the equation x + 13 = 18?Given the equation; x + 13 = 18.
We plug x = 6 into the equation
x + 13 = 18
6 + 13 ≠ 18
6 + 13 is not 18
x = 6 is not a solution to the equation x + 13 = 18.
Hence, Option C) No, because 6 + 13 = 18 is not true. is the correct answer.

ldentify the slope.
3x-2y= 10
Answer:
change it into slope intercept form: y=3/2x-5
Step-by-step explanation:
the slope is 3/2
Answer:
m = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
This is the answer because:
1) Use the slope-intercept form: y = mx + b to find the slope
1. The slope intercept form is y = mx + b where m is the slop and b is the y-intercept.
2. Subtract 3x from both sides of the equation:
-2y = 10 - 3x
3. Divide each term by -2 and simplify:
[tex]y=\frac{3}{2} -5[/tex]
4. Using the slope-intercept form, the slope is [tex]\frac{3}{2}[/tex]
Therefore, the answer is [tex]\frac{3}{2}[/tex]

What is the image of the point (9, – 7) after a rotation of 270° counterclockwise
about the origin?
Answer:
The image if the point is (-7, -9)
Step-by-step explanation:
If The point (x, y) rotated about the origin by angle 90° counterclockwise, then its image is (-y, x)If the point (x, y) rotated about the origin by angle 180° counterclockwise, then its image is (-x, -y)If the point (x, y) rotated about the origin by angle 270° counterclockwise, then its image is (y, -x)∵ The given point is (9, -7)
∴ x = 9 and y = -7
∵ The given point is rotated 270° counterclockwise about the origin
→ By using the third rule above
∴ The image of the point is (y, -x)
→ That mean change the sign of x-coordinate, then switch them
∵ x = 9 and y = -7
∴ The image if the point is (-7, -9)
