Answer:
x=4
Step-by-step explanation:
-7x=-28
-7 -7
x=4
Divide both sides by -7. A negative divided by a negative will give you a positive. So the answer would be x=4.
Answer:
x=4
you divide both sides by -7 to get the x by itself. -28 divided by -7 is 4.
Un automóvil recorre 1000 Km y consume 95 L de gasolina. Si la gasolina tiene un precio de $18.75 por cada litro ¿cuánto cuesta recorrer cada Km, en $/Km? (redondear a tres decimales)
Answer:
$1781.25
1 x 95= 95
18.75 x 95= 1781.25
miles say that, when a is any integer greater than 0, the value of a^-3 is always less than -a^3 because the exponent in a^-3 is less than the exponent in -a^3. is miles reasoning correct?
3x - 4 < 8 and 2x+ 2 > 4
20 points crq
Answer:
x<4 and x>1
Step-by-step explanation:
1) 3x-4<8
Add 4 to both sides first to isolate x.
3x-4<8
+4 +4
3x<12
Divide both sides by 3.
3x<12
/3 /3
x<4
2) 2x+2>4
Subtract both sides by 2 to isolate x.
2x+2>4
-2 -2
2x>2
Divide both sides by 2.
2x>2
/2 /2
x>1

Orbital Toys sells two types of sets of magnetic spheres, silver and brass. The store owner, Lucy Ball, pays $8 and $16 for each one set of silver magnetic spheres and brass magnetic spheres respectively. One set of silver magnetic spheres yields a profit of $3 while a set of brass magnetic spheres yields a profit of $5. Ms. Ball estimates that no more than 2000 sets of magnetic spheres will be sold every month and she does not plan to invest more than $20,000 in inventory of these sets. How many sets of each type of magnetic spheres should be stocked in order to maximize her total monthly profit? What is her maximum monthly profit?
Answer:
The maximum profit will be reached by buying 500 brass magnetic spheres and 1500 silver magnetic spheres.
Step-by-step explanation:
In order to solve this you need to create a system of equations, with two values that will create the answer we are looking for, the thing that we don't know here is how many of each are we buying so the number of silver magnetic spheres will be represented by "y" and the brass magnetic spheres will be represented by "x".
So we know that x+y=2000
That's our first equation, our second would be the expense, which would be
8x+16y=20,000
We now just solve for one of them
x=(2000-y)
8(2000-y)+16y=20,000
16,000-8y+16y=20,000
8y=4,000
y=500
So we know that the maximum profit will be reached by buying 500 brass magnetic spheres and 1500 silver magnetic spheres.

Use the properties of logarithms to write the following expression as one logarithm.
3 ln(x) + 2 ln(y) − 4 ln(x + 1)
Please show your work and explain, I would like to learn how to complete this type of problem!
Answer:
Step-by-step explanation:
hi! the log properties say that when logs are multiplied as log(xy), they can be expanded and added like log(x)+log(y). when logs are divided like log(x/y), they can be expanded as log(x)-log(y). when the log has an exponent like log(x^y), the exponent can be added to the front of the log like ylog(x). we can use these properties for this problem.
ln(x^3)+ln(y^2)-ln((x+1)^4)
ln(x^3*y^2)-ln((x+1)^4)

QUICK plzzzz. Don’t worry about the other questions just plz answer 17 for me :)
Answer:
a) Vf = at + Vi
b) 10 m/s
Step-by-step explanation:
Part A:
first bring the t to the other side, when doing this the t will become a numerator: at= Vf-Vi
now bring the Vi over to the other side and flip the sign: at + Vi = Vf
this can be rewritten as Vf = at + Vi
Part B:
substitute the numbers: Vf = (2)(3) + 4
solve to get: Vf = 10 m/s

Use polynomial identities to prove that 63^2=(60+32)^2
Answer:
Step-by-step explanation:
I'm not sure, but I think you mean
63^2 = 3969
60^2 = 3600
2*3 * 60 = 360
3^2 9
Total = 3969
This comes from x^2 + 2*x*y + y^2
where
x = 60
y = 3
Help me please!!!!!!!!
Step-by-step explanation:
To solve the equation for s we've got to leave s alone
[tex]n = \frac{s + 360}{180} \\ 180n = s + 360 \\ 180n - 360 = s[/tex]
Line t has a slope of 3/5 line u is perpendicular to t what is the slope of line u
Answer:
[tex]\frac{5}{3}[/tex] is the slope of the line
Step-by-step explanation:
When two lines are perpendicular, their slopes are inverse.
[tex]\frac{3}{5}[/tex] becomes [tex]\frac{5}{3}[/tex] because they are inverse. Just flip the numerator (top number) and denominator(bottom number).

Which of the following subsets of ℝ3×3 are subspaces of ℝ3×3? A. The 3×3 matrices of rank 2 B. The 3×3 matrices in reduced row-echelon form C. The 3×3 matrices with trace 0 (the trace of a matrix is the sum of its diagonal entries) D. The diagonal 3×3 matrices E. The 3×3 matrices with all zeros in the second row F. The invertible 3×3 matrices
Answer:
The answer is "Option C, Option D, and Option E".
Step-by-step explanation:
In point, A: Its matrix (aA+bB) for A, B matrices of rank 2 is not always of rank 2. for Rank(A+B) is smaller or equivalent to RankA+B.
In point B: The two matrices, A, B, and each entry is equal to or larger than zero. Then, take a = -1 = b, and so all entries (aA+bB) belong to the subset are less than or equal to Zero.hence.
In point C: We get the matrix (aA+bB) for A, B matrices with trace 0. Trace zero. (aA + bB) trace is (a×trace(A) + b×trace(B)) thus null.
In point D: For Both A and B, the matrix (aA+bB) is again diagonal for two diagonal matrices.
In point E: For Both A and B matrices, each insertion in second row zero will also have the second-row matrix (aA+bB) as zero.
In point F: In this case, A and B must become two reduced raw echelons, so that A+E is also a reduced raw shape.
Benny has a basket of 5 red balls, 3 yellow balls, and 2 green balls. He will pick one
ball at random. What is the probability that the next ball he randomly chooses will be
red or green?
Type the answer in the box as a fraction in simplest form.
Answer:
7/11 green or red balls
Step-by-step explanation:
5 + 3 + 2 = 11 = whole basket
5 + 2 = 7 = red + green
probability = 7 / 11 balls
Hope this helps!
The probability that the next ball he randomly chooses will be red or green is 7/10
ProbabilityFrom the question, we are to determine the probability that the next ball Benny randomly chooses will be red or green
From the given information,
Benny has a basket of 5 red balls, 3 yellow balls, and 2 green balls
∴ Total number of possible outcome = 5 + 3 + 2 = 10
Now we will determine the probability of picking red
Using the formula,
[tex]P(A) = \frac{Number\ of\ favourable\ outcome\ to\ A}{Total\ number\ of\ favourable\ outcomes}[/tex]
∴ [tex]P(R) = \frac{5}{10}[/tex]
For the probability of picking green
[tex]P(G) = \frac{2}{10}[/tex]
Then, the probability of red or green is
∴ [tex]P(R \ or \ G) = \frac{5}{10} + \frac{2}{10}[/tex]
[tex]P(R \ or \ G) = \frac{7}{10}[/tex]
Hence, the probability that the next ball he randomly chooses will be red or green is 7/10

Judge the following reasoning as true or false.
You are working for a tech company. You came up with an algorithm that performs a needed operation on n inputs in order of n operations. Someone else in the company simultaneously came up with an algorithm that performs the same task in order of log(n) operations. Then it follows necessarily that your algorithm will require more operations to perform this task and is therefore inferior and should not be used.
