Answer:
f(-2) = -6
Step-by-step explanation:
In the expression, to get f(-2);
we simply substitute the value of x with -2
We have this as;
f(-2) = -4(-2)^2 + 10
f(-2) = -4(4) + 10
f(-2) = -16 + 10
f(-2) = -6
If y varies directly as x, and y is 6 when x is 72, what is the value of y when x is 8?
1/9
2/3
54
96
Answer:
2/3
Step-by-step explanation:
you can set it up as x/y because it varies directly
so when y=6 x=72
72/6 = 12
so x will always be 12 times greater than y
x=12y
so if x=8
8=12y
y=8/12
y=2/3
What is the volume of the following rectangle prism? Plz help
Answer:
7 2/3 or 7.666
Step-by-step explanation:
To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.
since we only have two points we have to do
4/3 x 23/4 = 7 2/3 or 7.666
so the answer is 7 2/3 or 7.666

PLS HELP MEEE I NEED THE ANSWERS RN
Answers:
x= -10 and y= 16
3y = -6x - 12
3y = -6(-2y+22) -12
3y = 12y - 144
3y + -12y = 12y -144 + -12y
-9y = -144
divide -9 on both sides
y= 16
x= -2y+22
x= -2y+22
x= (-2)(16)+22
x= -10

Ali, Ben, and Cliff plant seedlings in their neighborhood park. Ali plants 40% of the total number of seedlings, Ben plants 45% of the total number of seedlings, and Cliff plants the rest of the seedlings. If Cliff plants 87 seedlings, how many seedlings do the three boys plant altogether?
Answer:
580 seedlings altogether.
Step-by-step explanation:
Given that,
Ali plants 40% of the total number of seedlings, Ben plants 45% of the total number of seedlings, and Cliff plants the rest of the seedlings. Cliff plants 87 seedlings.
The percentage of the seedling planted by Cliff = 100% - 45% - 40% = 15%
Let x = the total number of seedlings
[tex]15\%\ of\ x=87\\\\x=\dfrac{87\times 100}{15}\\\\x=580[/tex]
Hence, three boys plant 580 seedlings altogether.

One evening, the temperature drops 12 °F to become 37 °F. What was the temperature at the beginning of the evening? Write and solve an equation to represent this situation.
Answer: 49°F
Step-by-step explanation: x - 12 = 37, So all we have to do is reverse it. That means we add 37 and 12 to get the beginning temperature. 37 + 12 = 49. So at the beginning of the evening, it was 49°F.
Help please....I have no idea what I’m doing
Answer:
C) 8
Step-by-step explanation:
Use the formula
Slope = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]y_1[/tex] - any y value
[tex]x_1[/tex] - x value corresponding to y_1
similarly, you can pick y_2 and x_2 from the table.
Pick any two rows
Let's pick row 3 and 4
Slope = [tex]\frac{33-23}{5-3}[/tex]
=> 10/2
Slope = 5
Now formula
y = slope * x + intercept
y = 5x + intercept
intercept = y - 5x
Now take any row from the table and substitute above to calculate intercept
Taking row 3
intercept = 23 - 5 * 3
intercept = 8

What is the slope of the line that passes through the points (-10, 4) and (-10, 8)?
Write your answer in simplest form.
Answer:
The slope of the line is un-defined
Step-by-step explanation:
Explanation:-
Given points are ( -10 , 4) and (-10 ,8)
Slope of the line
[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
[tex]m = \frac{8-4 }{-10-(-10}) = \frac{4}{-10+10} = \frac{4}{0}[/tex]
m = ∞
The slope of the line is un-defined
In the given parallelogram, BELT,find the value of p,q,x,y
Answer:
5. x = 10, y = 6 6. p = 60°, q = 120°, x = 60° , y = 30°Step-by-step explanation:
5.
2x = 20 ⇒ x = 10
5y + 5 = 35 ⇒ 5y = 30 ⇒ y = 6
6.
m∠T = x = 180° - 90° - 30° = 60°
m∠E=m∠T ⇒ y = 180° - 90° - 60° = 30°
m∠B = m∠L = q = 180° - m∠E = 180° - 60° = 120°
m∠B = 30° + p + y ⇒ p = 120° - 30° - 30° = 60°

The height of a painting is √30 ft. Between which two consecutive whole numbers is √30? 7 and 8 6 and 7 4 and 5 5 and 6
Answer
5 and 6
Step-by-step explanation:
First | Find the square root of √30 (Put it in the calculator)
Answer | 5.47722557505...
Second | Round the number to the tenths
Anwer | 5.5 (ect the number in the hundreths place is greater than 5 so you bump up the 4 by 1 so 5.4 to 5.5)
Third | Get a line and see where 5.5 belongs it cant be 4 and 5 since the answer will need to be 4 or 5.0
Concusion | Here are the steps to find the answer hope this helped!
