What would this be? Please help.
Answer:
-176
Step-by-step explanation:
Let x = -8
f(-8) = 11 (-8-24) / 2
Simplify the parentheses
f(-8) = 11 ( -32)/2
= 11 (-16)
= 176
What is the value of 8 + 2^3 x 5?
Answer:
I think the answer is 48
Step-by-step explanation:
2^3 = 8
8 x 5 = 40
40 + 8 = 48
Determine whether the system of equations has no solution, one solution, or infinitely many solutions
y = - 3x + 5
y = 1/2x-2
Answer:
one solution
Step-by-step explanation:
y=-3x+5
y=1/2x-2
You can tell straight off the bat, it does have a solution, and it isn't infinite solutions. If it had no solution, it would have the same slope but different y-intercepts. If it had infinite solutions, the 2 equations would have to be the exact same. So there is only one solution.

Laura comprou 870 gramas de carne moida e vai dividir ingualmente em 3 pacotes. Quantas gramas terão em cada pacote?
Answer:
290 gramas
Step-by-step explanation:
Podemos interpretar a questão acima matematicamente como:
3 pacotes = 870 gramas
1 pacote = x
Multiplicação cruzada
3x = 1 × 870 gramas
Divida os dois lados por 3
3x / 3 = 1 × 870 gramas / 3
x = 290 gramas
Portanto, cada pacote conteria 290 gramas de carne moída

Jessica is selling books during the summer to earn money for college. She
earns a commission on each sale but has to pay for her own expenses.
After a month of driving from neighborhood to neighborhood and walking
door-to-door, she figures out that her weekly earnings are approximately a
linear function of the number of doors she knocks on.
She writes the equation of the function like this: E(x) = 10x - 30, where x is the
number of doors she knocks on during the week and E(x) is her earnings for
the week in dollars.
Which of the following are reasonable interpretations of the y-intercept of
Jessica's function?
Check all that apply.
A. She can earn $10 per week even if she does not knock on any
doors
B. Her expenses are $30 per week.
c. If she does not knock on any doors at all during the week, she will
lose $30
D. She will lose $10 per week if she does not knock on any doors.
Answer:
C. if 10x is the door she have to knock so the -30 is how much she will earn during the week and if she doesn't knock any then she will lose the whole $30 dollars . sorry i can't explain myself good but i think it is so
Answer: B and C (took the test)
Step-by-step explanation:
B. Her expenses are $30 per week
C. If she does not knock on any doors at all during the week, she will lose $30.

If (-10,8) is a point on the terminal side f a angle 0 in standard position what is the value of tan0?
Answer:
The value of the tangent is [tex]-\frac{4}{5}[/tex].
Step-by-step explanation:
Let be [tex]A(x,y) = (-10, 8)[/tex] on the terminal side of an angle in standard position and let be [tex]O(x,y)[/tex] the origin of the angle and the origin of the Cartesian plane. By definition of tangent, we make use of the following expression:
[tex]\tan \theta = \frac{y_{A}-y_{O}}{x_{A}-x_{O}}[/tex] (1)
Where:
[tex]x_{A}, x_{O}[/tex] - x-Coordinates of point A and point O.
[tex]y_{A}, y_{O}[/tex] - y-Coordinates of point A and point O.
If we know that [tex]x_{A} = -10, x_{O} = 0[/tex], [tex]y_{A} = 8[/tex] and [tex]y_{O} = 0[/tex], then the value of the tangent is:
[tex]\tan \theta = \frac{y_{A}-y_{O}}{x_{A}-x_{O}}[/tex]
[tex]\tan \theta = \frac{8-0}{-10-0}[/tex]
[tex]\tan \theta = -\frac{4}{5}[/tex]
Jasmine has $28.80 in savings. Her sister has 2½ as much as Jasmine. How much money do the two girls have together
Answer:
$100.80
Step-by-step explanation:
Total money = 28.80 (Jasmine) + 2.5 x 28.80 (Sister)
Total money = 28.80 + 72 = $100.80
Answer:
$100.80
Step-by-step explanation:
y=28.80+(28.80x2.5)
y=28.80+72
y=100.80

If the hypotenyse of an isosceles triangle is 8 inches, is there enough information to find the length of the legs? If yes, find the length of the legs. Round to the nearest tenth if necessary.
Answer: 5..6 in.
Step-by-step explanation:
Given
Hypotenuse of isosceles triangle is 8 inches
In isosceles triangle two sides are equal
Suppose the other side is x
Using Pythagoras we can write
[tex]\Rightarrow x^2+x^2=8^2\\\Rightarrow 2x^2=64\\\Rightarrow x^2=32\\\Rightarrow x=4\sqrt{2}\approx 5.6\ in.[/tex]
Therefore, the lengths of the legs is 5.6 inches
1. 120+3t when t= 6
2. 4c+ 2b. C=3 and b=5
Answer:
The right solution is:
(1) 138
(2) 22
Step-by-step explanation:
The given values are:
t = 6
c = 3
b = 5
(1)
The given expression is:
= [tex]120+3t[/tex]
On putting the value of "t", we get
= [tex]120+3(6)[/tex]
= [tex]120+18[/tex]
= [tex]138[/tex]
(2)
The given expression is:
= [tex]4c+2b[/tex]
On putting the values, we get
= [tex]4(3)+2(5)[/tex]
= [tex]12+10[/tex]
= [tex]22[/tex]

what percent of 144 is 36
no links
Answer:
25
Step-by-step explanation:
We already have our first value 36 and the second value 144. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
STEP 1 Y = 36/ 144
By multiplying both numerator and denominator by 100 we will get:
STEP 2 Y = 36/ 144 × 100/ 100 = 25/ 100
STEP 3 Y = 25
Finally, we have found the value of Y which is 25 and that is our answer.
If you want to use a calculator to find 36 is what percent of 144, simply enter 36 ÷ 144 × 100 and you will get your answer which is 25

Use Desmos graphing calculator
Answer:
x = -2y^2
Explanation Part 1:
It's not vertical, and thus it's not a standard (y = ax^2 + b) parabola.
This must mean it's either x = 2y^2 or x = -2y^2
Explanation Part 2:
You can test values into either one to check if it works
Take (-2, 1) for example, doesn't have to be a precise coordinate pair:
First Equation
x = 2y^2
-2 = 2(1)^2
-2 = 2(1)
-2 = 2
DOESN'T WORK!
Second Equation
x = -2y^2
-2 = -2(-1)^2
-2 = -2(1)
-2 = -2
IT WORKS!

The Asian elephant is an endangered species with a current population of 45,000. This species is said to be experinceing a decline of 4.5% per year. After how many years should we expect the Asian elephant poputation ot be approximately 35,746?
Answer:
5 years
Step-by-step explanation:
Given that
The current population is 45,000
The rate of interest in declining would be 4.5% per year
The expected population is 35,746
We need to find out the no of years
Since the rate of interest decrease by 4.5% per year so after decreasing it the percentage would be 0.955
Now
Year 1 = 45,000 × 0.955 = 42,975
Year 2 = 42,975 × 0.955 = 41,041.125
Year 3 = 41,041.125 × 0.955 = 39,194.27
Year 4 = 39,194.27 × 0.955 = 37,430.53
Year 5 = 37,430.53 × 0.955 = 35,746.16
Hence, the no of years would be 5
