Answer:
-6
Step-by-step explanation:
if they were both positive numbers, it would be 6. But when you multiply a negative by a positive, the answer is negative.
Answer:
-6
Step-by-step explanation:
When you multiply a positive number by another positive number, you will always get a positive number as your answer. Same thing for negative. If you multiply a negative by a negative, you will always get a positive. However, when you multiply a negative by a positive, you will always get a negative number.
Since you know this, you can multiply 2 by 3, which is 6. Because 2 is negative and 3 is positive, you know that the answer must be negative. Therefore, you add the negative symbol to 6, giving you -6.
I hope this isn't too confusing. Please let me know if you have any more questions. Good luck!

What is a number system?A number system is described as a technique of composing to represent digits. It is the mathematical inscription for describing the numbers of a given set by using numbers or other characters in a uniform method. It delivers a special presentation of every digit and describes the arithmetic structure.
Here,
If three of the terms are like terms, then we can combine them into a single term. Let's say that the expression with 4 terms is:
a + b + c + d
where a, b, and c are like terms. Then we can combine them to get:
(a + b + c) + d
which is an expression with only 2 terms.
So the equivalent expression with the least number of terms has 2 terms. We can do this by combining the like terms to simplify the expression.

Sandra buys stamps that cost $0.65 each she spends a total of $158.60 on the stamps. To determine how many stamps she buys, she needs to divide $158.60 by $0.65
Answer:
True
Step-by-step explanation:
When she divides both numbers, she can find out how many stamps she bought. When you solve the equation, we can see that she bought 244 stamps. We can check this by doing inverse operations. 244 x 0.65 (the price for each stamp) = 158.60

solve (x- 4.5)/2=5.5 for x
please help asap
Answer:
x=31/2
Step-by-step explanation:
don't have steps but its right.
Answer:
x = 31/2 = 15 1/2 = 15.5
Step-by-step explanation:
(x- 4.5)/2=5.5
Multiply both sides by 2.
x−4.5=5.5×2
Multiply 5.5 and 2 to get 11.
x−4.5=11
Add 4.5 to both sides.
x=11+4.5
Add 11 and 4.5 to get 15.5.
x=15.5

i figured out a. is angle B but i cant figure out statement 2 pls help!!!!
Answer:
DC
Step-by-step explanation:
If you consider that we're looking at the same shape at two different scales, then we can simply look at which sides correlate with one another.
In the smaller shape, GH is in the same place as AB in the bigger one.
Similarly, the smaller shape has DJ in the same place that the larger one has DC. This means that dC is the answer to question b.

What is the equation that models this scenario?
How many pounds of apples did Angelica buy?
Answer:
What is the equation that models this scenario?
✔ A + 5/4 = 19/4
and
How many pounds of apples did Angelica buy?
✔ 14/4 = 7/2
Step-by-step explanation:
Hope this helps!! :)
The equation A + 5/4 = 19/4 represents the number of pounds of apples Angelica bought, and the number of apples Angelica bought is 7/2 pounds.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let A = the number of pounds of apples Angelica bought.
Then the model that represents the number of pounds of apples Angelica bought:
A + 5/4 = 19/4
A = 19/4 - 5/4
A = 14/4 = 7/2 pounds
Thus, the equation A + 5/4 = 19/4 represents the number of pounds of apples Angelica bought and the number of apples Angelica bought is 7/2 pounds.

What are exponential functions?When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function. There usual form is specified below. They are written in several such equivalent forms.
For example, [tex]y = a.b^x[/tex] , where a is a and b are constants is an exponential function.
How to calculate simple interest's amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% annually, and it is left for T years for that simple interest, then the interest amount earned is given by:
[tex]I = \dfrac{P \times R \times T}{100}[/tex]
How to calculate compound interest's amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that compound interest, then the interest amount earned is given by:
[tex]CI = P(1 +\dfrac{R}{100})^T - P[/tex]
The final amount becomes:
[tex]A = CI + P\\A = P(1 +\dfrac{R}{100})^T[/tex]
Usually these two rates are used on money. The compound interest is exponential as it has power T as a variable, but for simple interest, there is no variable exponent.
Both are positive, and growth of exponential function is always going to surpass the growth of linear function (can be proven by derivatives).
Since we are not given the function's equation, we cannot correctly calculate the value just from graph, but as in 14 years, the blue line is already close to red line so it will likely cross it after 6 more years (thus total 20 years) because of good growth.
Thus, the person who will have more money by year 20 is given by: Option C: Tyler, because his money is increasing exponentially

Answer:
x = -4
Step-by-step explanation:
x= 3 is a parallel to y axis. So a parallel line to x = 3 must be parallel to y axis.
A line parallel to y axis has a generic equation: x = h. We know that the line passes to the point with has x coordinate = -4
So the equation is x= -4

Answer:
6. (A, B, C) ≈ (112.4°, 29.5°, 38.0°)
7. (a, b, C) ≈ (180.5, 238.5, 145°)
Step-by-step explanation:
My "work" is to make use of a triangle solver calculator. The results are attached. Triangle solvers are available for phone or tablet and on web sites. Many graphing calculators have triangle solvers built in.
__
We suppose you're to make use of the Law of Sines and the Law of Cosines, as applicable.
6. When 3 sides are given, the Law of Cosines can be used to find the angles. For example, angle A can be found from ...
A = arccos((b² +c² -a²)/(2bc))
A = arccos((8² +10² -15²)/(2·8·10)) = arccos(-61/160) = 112.4°
The other angles can be found by permuting the variables appropriately.
B = arccos((225 +100 -64)/(2·15·10) = arccos(261/300) ≈ 29.5°
The third angle can be found as the supplement to the other two.
C = 180° -112.411° -29.541° = 38.048° ≈ 38.0°
The angles (A, B, C) are about (112.4°, 29.5°, 38.0°).
__
7. When insufficient information is given for the Law of Cosines, the Law of Sines can be useful. It tells us side lengths are proportional to the sine of the opposite angle. With two angles, we can find the third, and with any side length, we can then find the other side lengths.
C = 180° -A -B = 145°
a = c(sin(A)/sin(C)) = 400·sin(15°)/sin(145°) ≈ 180.49
b = c(sin(B)/sin(C)) = 400·sin(20°)/sin(145°) ≈ 238.52
The measures (a, b, C) are about (180.5, 238.5, 145°).
