The total cost of one appetizer and four meals is $89. The price of the appetizer is $9 and each meal is the same price as m. What is the price of one meal? M = ?
Answer:
$20
subtract 9 from 89 beacuse we need to find how much is 1 meal and the 9 represents 1 appetizer
89-9=80
since there are 4 meals divide 80 by 4
80÷4= 20
and u get $20 per meal
Step-by-step explanation:
The cost of an appetizer = 9
The cost of a meal = m
The cost of an appetizer and 4 meals = 9 + 4(m) = 89
4m +9 = 89 Your equation, solve for m
4m - 9 + 9 = 89 - 9 Bring the constants to one side
4m = 80 Simplification
4m/4 = 80/4 isolating the variable
m= 20 Your answer!!!
A meal costs 20 dollars
I hope this helps!!!
If you wanted to check the answer...
Do the same thing but substitute for m
4 (20) + 9 = 89
80 + 9 = 89
89 = 89
The answer should be correct

Is RS perpendicular to DF? Select Yes or No for each statement. R (6, −2), S (−1, 8), D (−1, 11), and F (11 ,4) R (1, 3), S (4,7), D (3, 9), and F (15, 0) R (−5, −5), S (0, 2), D (8, 3), and F (1, 8)
I'll do the first one to get you started.
Find the slope of the line between R (6,-2) and S (-1,8) to get
m = (y2-y1)/(x2-x1)
m = (8-(-2))/(-1-6)
m = (8+2)/(-1-6)
m = 10/(-7)
m = -10/7
The slope of line RS is -10/7
Next, we find the slope of line DF
m = (y2 - y1)/(x2 - x1)
m = (4-11)/(11-(-1))
m = (4-11)/(11+1)
m = -7/12
From here, we multiply the two slope values
(slope of RS)*(slope of DF) = (-10/7)*(-7/12)
(slope of RS)*(slope of DF) = (-10*(-7))/(7*12)
(slope of RS)*(slope of DF) = 10/12
(slope of RS)*(slope of DF) = 5/6
Because the result is not -1, this means we do not have perpendicular lines here. Any pair of perpendicular lines always has their slopes multiply to -1. This is assuming neither line is vertical.
I'll let you do the two other ones. Let me know what you get so I can check your work.
thank you so much for you help
How do you find the average rate of change for f(x)=9-x^2 between two points: x=0 to x=3?
Please I have a final tomorrow and I’m clueless
Answer:
The average rate of change is -3.
Step-by-step explanation:
We are given the function:
[tex]f(x)=9-x^2[/tex]
And we want to find the average rate of change from x = 0 to x = 3.
In other words, we will compute the function at the two endpoints, and then find the slope of the line that crosses the two points.
For our first endpoint at x = 0, our function evaluates to:
[tex]f(0)=9-(0)^2=9[/tex]
So, our first point is (0, 9).
For our second endpoint at x = 3, our function evaluates to :
[tex]f(x)=9-(3)^2=0[/tex]
So, our second point is (3, 0).
Then by the slope formula, our average rate of change will be:
[tex]\displaystyle m=\frac{0-9}{3-0}=\frac{-9}{3}=-3[/tex]

A force of 84N is applied to an area of
15cm". Work out the pressure in N/cm².
cm3)
Answer: 5.6 N/cm^2
============================================
Work Shown:
Pressure = (Force)/(Area)
P = F/A
P = (84 N)/(15 cm^2)
P = (84/15) (N/cm^2)
P = 5.6 N/cm^2
For every square cm, 5.6 newtons of force is applied.
-------------
Extra info:
If you wanted to convert this to pascals, then you would need to convert 15 cm^2 to 0.0015 square meters. Then apply the formula above to get 56,000 pascals. 1 pascal is equivalent to 1 N/m^2.

If f'(x)=3x^2+2x and f(2)=3 then f(1)=
helppppp
Answer:
[tex]f(1)=-7[/tex]
Step-by-step explanation:
We are given the derivative:
[tex]f^\prime (x) = 3 x^2 + 2x[/tex]
And the initial condition that f(2)=3.
And we want to find f(1).
So, to find our original function f(x), we will find the antiderivative of f'(x). Hence:
[tex]\displaystyle f(x)=\int f^\prime(x)\, dx=\int3x^2+2x\, dx[/tex]
By integrating, we acquire:
[tex]f(x)=x^3+x^2+C[/tex]
Since we know that f(2)=3:
[tex]3=(2)^3+(2)^2+C[/tex]
It follows that:
[tex]C=-9[/tex]
Therefore, our function is given by:
[tex]f(x)=x^3+x^2-9[/tex]
Therefore:
[tex]f(1)=(1)^3+(1)^2-9 = -7[/tex]
Here we want to solve a differential equation, we will find that our function is f(x) = x^3 + x^2 -9
Solving the differential equation.So we want to find f(x) such that we know f'(x).
We know that:
f'(x) = 3x^2 + 2x
To get f(x) we just need to integrate, we will get:
[tex]f(x) = \int\limits {3x^2 + 2x} \, dx = x^3 + x^2 + c[/tex]
Where c is a constant of integration.
Now, we know that f(2) = 3, with that we can find the value of c.
f(2) = 2^3 + 2^2 + c = 3
8 + 4 + c = 3
c = 3 - 12 = -9
So the function is:
f(x) = x^3 + x^2 -9

find the gcf 24 and 72. 16 and 18
Answer:
for 24 and 72 its 24 for 16 and 18 it is 2
Step-by-step explanation:
Today everything at a store is on sale the store offers a 20% discount the discounted price of the hat is $18 what is the regular price (The answer is not 21.6)
The answer is 22.5 But I don’t know how to get there
80% = $18
(divide both sides by 80 to find 1%)
1% = 0.225
(multiply both sides by 100 to find 100%)
100% = $22.50
Find the smallest value of k such that the LCM of
k and 6 is 60
Answer: The smallest valuest value for k is 10, such that LCM of k and 6 is 60.
Step-by-step explanation:
We know that, LCM = Least common multiple.
For example : LACM of 12 and 60 is 60.
If LCM of k and 6 is 60.
i.e. the least common multiple of k and 6 is 60.
Since, 10 x 6 = 60.
The smallest valuest value for k should be 10, such that LCM of k and 6 is 60.
Hence, the smallest value of k is 10.
Afla cate procente reprezinta numarul a din numarul b daca a si b sunt invers proportionale cu numerele 12 si 15
Răspuns:
125%
Explicație pas cu pas:
a și B sunt invers proporționale cu numerele 12 și 15
Proporționalitate inversă:
a = k / y
Prin urmare ;
a = k / 12 - - - (1)
b = k / 15 - - - (2)
Procent care reprezintă a de la b
a = 100%
b = x
k / 12 = 1
k / 15 = x
Înmulțirea încrucișată:
x * k / 12 = k / 15
x = k / 12 ÷ k / 15
x = k / 12 * 15 / k
x = 15/12
x = 1,25
1,25 * 100% = 125%
Findx.
Assume the middle line is a midsegment in the problems below:
HELPPPPPP
Answer: x = 12
midsegment is 16 units long
bottom side is 32 units long
===============================================
Work Shown:
The midsegment 2x-8 is parallel to the bottom side 2x+8
The bottom side is twice as long compared to the midsegment (since the midsegment is half the length of the bottom side).
We can say
bottom side = 2*(midsegment)
2x+8 = 2*(2x-8)
2x+8 = 4x-16
2x-4x = -16-8
-2x = -24
x = -24/(-2)
x = 12
--------------------
Extra info:
Now that we know x, we can find the length of those segments
midsegment = 2x-8 = 2*12-8 = 24-8 = 16
bottom side = 2x+8 = 2*12+8 = 24+8 = 32
Note the bottom side (32) is exactly twice as long compared to the midsegment (16). This confirms we have the correct x value.
