Which of the following best describes the equation below? y = 5x - 15
a.neither linear or non linear
b.non linear
c.both linear and non linear
d.linear
Answer:
D linear
Step-by-step explanation:
We can tell pretty easily that this is a linear equation. How? Look at the highest degree of x!
This means the highest exponent of x. It looks like we have 5x, which you can think of as 5x to the first power. Whenever the highest exponent is 1, the equation is linear.
In a representative survey 9 out of 12 middle schoolers prefer
doughnuts to candy bars. How many doughnuts would you predict you
need for a group of 250 middle schoolers? How many candy bars?
Answer:
187.5 doughnuts (about 188)
62.5 candy bars (about 63)
Step-by-step explanation:
So the proportion of middle schoolers who prefer doughnuts is p = 9/12. That means the proportion of middle schoolers who prefer candy is 1 - 9/12 = 3/12.
The number of middle schoolers is n = 250.
Let X represent the number of doughnuts you need. The expected number is E(X) = np, so multiply them together:
E(X) = np
E(X) = 250 * 9/12 = 187.5 doughnuts
Let Y represent the number of candy bars you need. The expected number is E(Y) = np, so multiply them together:
E(Y) = np
E(Y) = 250 * 3/12 = 62.5 candy bars
Answer:
250/12=20.83
so there is about 21 times more people
20.8333 x 9 = 187.5
250-187.5=62.5
(I am going to put 62 so when you add up it will be 250 instead of 251)
about 188 people will have donuts and about 62 candy bars

Pls help!!! Which steps would you use to solve this equation? Check all that apply.
p + 7 = 12
O Subtract 7 from both sides of the equation
a Subtract 7 from 7.
7 -7 = 0 and 12 - 7 = 5, so p = 5.
I Substitute 12 for p to check the solution
O Substitute 5 for p to check the solution.
Answer:
you subtract 7 from both sides

y=x-7
y=6
simplify the answer as much as possible
Answer:
x=13 and y =6
Step-by-step explanation:
y=x-7
y=6
Substitute y=6 into the first equation
6 = x-7
Add 7 to each side
6+7= x-7+7
13 = x
x=13 and y =6

2)..... 1/4 x -2/5 x = 39
Answer:
x=-260
Step-by-step explanation:
1/4x-2/5x=39
Find a common denominator:
5/20x-8/20x=39
Combine:
-3/20x=39
Multiply both sides by -20/3:
x=39(-20/3)
x=-780/3
x=-260

Find the solutions for a triangle with a = 16, c =12, and B = 63º.
a. A = 71.6°; C = 52.89; b =12.0
C. A = 68.6° C = 45.40; b=12.0
b. A = 71.6°; C = 45.40; b =15.0
d. A = 68.6°; C = 52.89; b=15.0
Answer:
b. A = 71.6°; C = 45.40°; b =15.0
Step-by-step explanation:
The missing values can be found with the help of the Law of Cosine and properties of triangles:
Side b (Law of Cosine)
[tex]b = \sqrt{a^{2}+c^{2}-2\cdot a \cdot c \cdot \cos B}[/tex]
[tex]b = \sqrt{16^{2}+12^{2}-2\cdot (16)\cdot (12) \cdot \cos 63^{\circ}}[/tex]
[tex]b \approx 15.022[/tex]
Angle A (Law of Cosine)
[tex]\cos A = -\frac{a^{2} - b^{2}-c^{2}}{2\cdot b \cdot c}[/tex]
[tex]\cos A = - \frac{16^{2}-15.022^{2}-12^{2}}{2\cdot (15.022)\cdot (12)}[/tex]
[tex]\cos A = 0.315[/tex]
[tex]A= \cos^{-1} 0.315[/tex]
[tex]A \approx 71.639^{\circ}[/tex]
Angle C (Sum of internal angles in triangles)
[tex]C = 180^{\circ} - 63^{\circ} - 71.639^{\circ}[/tex]
[tex]C = 45.361^{\circ}[/tex]
Hence, the right answer is B.

Paul weighs 36 kg. Felix weighs half as much as Paul, and Frank weighs 4 kg more than Felix.
Answer:
Idk what you need but here is everything possible
Step-by-step explanation:
Paul = 36kg
Felix = 18kg
Frank = 22kg
36+18+22=76
Their weight all together is 76kg.
Answer:
Paul is 36 kg
Felix is 18 kg
Frank is 22 kg
Step-by-step explanation:
Pauls answer is in the question (36kg)
Felix is half of paul 36/2=18
Frank is 4 kg more than Felix 36/2=18 18+4=22

Infinitely Many Solutions
2x + 9 + 3x + x =
2 +
Answer:
so for the x it will be 6x to get no solution
Step-by-step explanation:
see if you add 2x+3x+x you get 6x for getting no solution you have to subtract from same number which will be 6x
what is the equation of the line passing through ( -5, -3 ) and perpendicular
to the line representing the equation y = - 5/7x + 2?
Answer:
y = 7/5x + 4
Step-by-step explanation:
use the slope from the equation -5/7 and take the negative reciprocal to get the perpendicular slope = 7/5. Then use the equation y=mx+b. Plug in x and y from the point given and the new slope and solve for b.
(-3) = (7/5)(-5) + b, (-3) = -7 + b, add 7 to both sides. b = 4. Rewrite the equation now to be y = 7/5x + 4

Your drawer contains seven red socks and five green socks. It's too dark to see which are which. What is the
probability that the two socks that you pick are both red if you don't replace the first sock after you draw it?
7/24
7/12
7/15
14/35
Answer:
7/22
Step-by-step explanation:
Probability of picking a red sock the first time: 7/12
Probability of picking a red sock the second time: 6/11 (Since you already took out one sock, thus decreasing both the number of red and total socks in the drawer.)
7/12 * 6/11 = 42/132
42/132 = 7/22

What is the probability of rolling a die 6 times and getting the numbers 1, 2, 3, 4, 5, 6 in that order? Select the best answer from the choices provided.
A. 0.001389
B. 0.000129
C. 0.000021
D. 0.0000038
Answer:
C. 0.000021
Step-by-step explanation:
Each roll of the die is an independent event.
The probability of rolling a 1, then a 2, then a 3, then a 4, then a 5, then a 6 is the product of the 6 individual probabilities.
Probability of rolling a 1:
There are 6 possible outcomes, rolling 1, 2, 3, 4, 5, or 6.
There is one desired outcome, rolling a 1.
p(1) = 1/6
Probability of rolling a 2:
Similar to rolling a 1, there is 1 desired outcome,rolling a 2, out of 6 possible outcomes.
p(2) = 1/6
The same is true for rolling a 3, 4, 5, or 6. Each one has a probability of 1/6.
p(1, 2, 3, 4, 5, 6, in that order) = p(1) * p(2) * p(3) * p(4) * p(5) * p(6)
= (1/6)^6
= 1/6 * 1/6 * 1/6 * 1/6 * 1/6 * 1/6
= 1/46,656
= 0.000021433
Answer: C. 0.000021
