Answer:
b=3Step-by-step explanation:
2b+8-5b+3=-13+8b-9
Combine like terms
-3b+11=8b-22
Subtract 11 from both sides:
-3b+11-11=8b-22-11
-3b=8b-33
Subtract 8b from both sides:
-3b-8b=8b-33-8b
-11b=-33
Divide both sides by -11:
-11b/-11=-33/-11
b=3

Which statements are true about the ordered pair (10, 5) and the system of equations?
{2x−5y=−5x+2y=11
Select each correct answer.
A.
The ordered pair (10, 5) is a solution to the first equation because it makes the first equation true.
B. The ordered pair (10, 5) is a solution to the second equation because it makes the second equation true.
C. The ordered pair (10, 5) is not a solution to the system because it makes at least one of the equations false.
D. The ordered pair (10, 5) is a solution to the system because it makes both equations true.
Answer:
The answer is C
Step-by-step explanation:
The entire equation is a system ( meaning everything equals each other) when you plug in the ordered pair (10,5) you dont get the same number meaning that nothing adds up or equals each other
pat bought 5.5 pounds of grapes for a party he spent $6.60. how much did he pay per pound
hi how do add in math
Answer: just put whatever numbers you have together and then see what the both add up to like what number they make
Answer:
Hi! I'm going to try to explain this in the best way possible. Basically, when adding in math, we're taking 2 or more numbers, and combining their values to make a different number. For example, if we have 1 and 1, which would be represented as 1 + 1, that would be the value of 1 added to the value of 1, which is 2. You can also do this on your fingers. Since we have 10 fingers, you would count 1 of them and another 1 of them to get 2 fingers! If we try a different problem, such as 2 + 1, that would be the sum of the value of 2 and the value of 1. When counting on your fingers, that would be 2 fingers and another finger. That's 3 fingers. 2 added to 1 is 3! I hope this makes some sort of sense! Tell me if you need more clarification :)

The value of Tan(A - B) is -0.1295.
TrigonometryTrigonometry deals with the relationship between the sides and angles of a right-angle triangle.
Right angle triangleIt is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.
Given
Sin A = 5 ÷ 13 and Tan B = -√3.
To findThe value of tan(A - B).
How to find the value of tan(A - B)?The angle A will be,
[tex]\begin{aligned} \rm sin A &= \dfrac{5}{13}\\\\\rm A &= \rm sin^{-1} \dfrac{5}{13}\\\\\rm A &= 22.62^o\\\\\end{aligned}\\But\ for\ the\ \dfrac{\pi}{2} < A < \pi\\\\A = 22.62^o + 90^o\\\\A = 112.62^o[/tex]
Similarly for angle B,
[tex]\begin{aligned} \rm tan B &= -\sqrt{3} \\\\\rm B &= \rm tan^{-1} -\sqrt{3} \\\\\rm B &= -60^o\\\\\end{aligned}\\\rm But\ for\ the\ \dfrac{\pi}{2} < B < \pi\\\\B = -60^o + 180^o\\\\B = 120^o[/tex]
Then tan (A - B) will be
Tan(A - B) = tan(112.62 - 120)
Tan(A - B) = tan(-7.38)
Tan(A - B) = -0.1295
Thus, the value of Tan(A - B) is -0.1295.

A person invests 6000 dollars in a bank. The bank pays 6.25% interest compounded monthly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 8800 dollars?
Answer:
6.1
Step-by-step explanation:
A person invests 6000 dollars in a bank. The bank pays 6.25% interest compounded monthly. The person leaves the money in the bank until it reaches 8800 dollars for 6.1 years.
How does compounding work?Suppose that the initial amount of something is P.
Let after one unit of time, it increases by R% (per unit time) and compounds on the resultant total of that quantity, then, after T such units of time, then the quantity would increase to:
[tex]A = P(1 + \dfrac{R}{100})^T[/tex]
A person invests 6000 dollars in a bank. The bank pays 6.25% interest compounded monthly.
Given that :
Principal = 6000
Interest (r) = 6.25% compounded annually
Calculate time, t, if final amount A = 8800
Using the compound interest formula
[tex]A = P(1 + \dfrac{R}{100})^T[/tex]
A = final amount
n = number of times interest is applied per period
[tex]8800 = 6000(1 + {0.0625})^{t}[/tex]
[tex]8800 = 6000(1 + {0.0625})^{t}\\\\\\8800 = 6000({1.0625})^{t}\\\\\\\dfrac{8800} {6000}=({1.0625})^{t}\\\\\\1.46 =({1.0625})^{t}[/tex]
Take the log of both sides
[tex]log 1.46 = t log 1.0675\\\\0.1643 = 0.0263289t\\\\t = 6.1[/tex]

Answer:
(0, -2) and (1, 0)
Step-by-step explanation:
y = x² + x - 2 and y = 2x - 2
y = x² + x - 2 ⇔ do not change; y = x² + x - 2
y = 2x - 2 ⇔ multiply by -1 ; -y = - 2x + 2
Now add the two equations:
y = x² + x - 2
(+) -y = - 2x + 2
0 = x² - 2x + x + 0
0 = x² - x
0 = x (x - 1) Factor out x
0 = x; 0 = x - 1 Set each factor = to 0 and solve.
x = 0; x = 1
Substitution the value of x into both equations and solve for y
If x = 0 If x = 1
y = (0)² + 0 - 2 ; y = 2(0) - 2 y = 1² + 1 - 2 ; y = 2(1) -2
y = 0 +0 -2 ; y = 0 - 2 y = 1 + 1 -2 ; y = 2 - 2
y = -2 ; y = -2 y = 0 ; y = 0

A florist charges $5.00 for delivery plus an additional $1.00 per mile from the flower shop. The florist pays the delivery driver $0.75 per mile and $3.50 for gas per
delivery. If x is the number of miles a delivery location is from the flower shop, what expression models the amount of money the florist earns for each delivery?
Find the function that models the amount of money the florist earns for each delivery.
The florists charges and delivery are illustrations of linear functions
The amount made by the florist per delivery is y = 1.5 + 0.25x
How to determine the functionsFor the charges, we have:
Delivery = $5.00Rate = $1.00 per mileRepresent the cost with y, and the number of miles with x.
The function that represents the amount the florist made is:
y = 5 + x
For the delivery, we have:
Gas = $3.50Rate = $0.75 per mileThe function that represents the delivery is:
y = 3.5 + 0.75x
The amount made by the florist per delivery is then calculated as:
y = 5 - 3.5 + x - 0.75x
y = 1.5 + 0.25x

Camden is going to invest $600 and leave it in an account for 12 years. Assuming the
