Answer: $5933.04
Step-by-step explanation:
Principal = $5900
Rate = 8%
Time = 7 years
Simple interest = PRT/100
= (5900 × 8% × 7)/100
= (5900 × 0.08 × 7) / 100
= 3304/100
= $33.04
Total amount = Principal + Interest
= $5900 + $33.04
= $5933.04
Solve for bbb. Reduce any fractions to lowest terms. Don't round your answer, and don't use mixed fractions. 30b+53 \geq 18b -8330b+53≥18b−8330, b, plus, 53, is greater than or equal to, 18, b, minus, 83
Answer:
b ≥ - 34 / 3
Step-by-step explanation:
Given the inequality :
30b+53≥18b−83
Collect like terms
30b - 18b ≥ - 83 - 53
12b ≥ - 136
Divide both sides by 12
12b / 12 ≥ - 136 / 12
b ≥ - 34 / 3
Hence, b ≥ - 34/3
Answer:
b≥− 34/3
Step-by-step explanation:
#1: Solve the linear system below using the elimination method. Type your
answer as an ordered pair in the form (#,#).*
5x + 3y = 1
-5x – 7y = 31
The given linear system is:
[tex]\displaystyle \left \{ {{5x+3y=1} \atop {-5x-7y=31}} \right.[/tex]
Linear systems can be solved using either elimination or substitution. However, the question is asking to solve using elimination, so I will use that method.
When eliminating, you can either eliminate x or y. In this system, x is much easier to eliminate. The x variable in the first equation is 5x, and in the second equation, it is -5x. Since 5 and -5 cancel each other out, you don't need to do anything other than add.
[tex]5x+3y=1\\-5x-7y=31[/tex]
[tex]\displaystyle 3y-7y=1+31\\-4y=32[/tex]
Lastly, you need to leave the variable y alone. The variable is currently -4y or -4 times y. To remove it, you need to do the opposite of it, which is dividing by -4.
Divide both sides by -4:
[tex]\displaystyle\frac{-4y}{-4} =\frac{32}{-4}[/tex]
[tex]\displaystyle y=-8[/tex]
Now that you have the value of y, substitute it into one of the equations to find x. I will be substituting it into the first equation.
[tex]\displaystyle 5x+3y=1 \rightarrow 5x+3(-8)=1[/tex]
Open the parentheses and multiply:
[tex]5x-24=1[/tex]
Move 24 to the other side to leave the variable alone:
[tex]5x-24+24=1+24[/tex]
You will be adding since you're "removing" it by doing the opposite of it.
[tex]5x=25[/tex]
Lastly, divide both sides by 5 to leave x alone.
[tex]\displaystyle \frac{5x}{5} =\frac{25}{5}[/tex]
[tex]x=5[/tex]
[tex]\displaystyle (x,y) \rightarrow (5, -8)[/tex]
The answer is (5, -8).

Step-by-step explanation:
Write the equation of the quadratic function whose graph passes through [tex](-3,2)[/tex], [tex](-1,0)[/tex], and [tex](1,6)[/tex].
Answer:
[tex]f(x)=x^2+3x+2[/tex]
Step-by-step explanation:
We want to write the equation of a quadratic whose graph passes through (-3, 2), (-1, 0), and (1, 6).
Remember that the standard quadratic function is given by:
[tex]f(x)=ax^2+bx+c[/tex]
Since it passes through the point (-3, 2). This means that when [tex]x=-3[/tex], [tex]f(x)=f(-3)=2[/tex]. Hence:
[tex]f(-3)=2=a(-3)^2+b(-3)+c[/tex]
Simplify:
[tex]2=9a-3b+c[/tex]
Perform the same computations for the coordinates (-1, 0) and (1, 6). Therefore:
[tex]0=a(-1)^2+b(-1)+c \\ \\0=a-b+c[/tex]
And for (1, 6):
[tex]6=a(1)^2+b(1)+c\\\\ 6=a+b+c[/tex]
So, we have a triple system of equations:
[tex]\left\{ \begin{array}{ll} 2=9a-3b+c &\\ 0=a-b+c \\6=a+b+c \end{array} \right.[/tex]
We can solve this using elimination.
Notice that the b term in Equation 2 and 3 are opposites. Hence, let's add them together. This yields:
[tex](0+6)=(a+a)+(-b+b)+(c+c)[/tex]
Compute:
[tex]6=2a+2c[/tex]
Let's divide both sides by 2:
[tex]3=a+c[/tex]
Now, let's eliminate b again but we will use Equation 1 and 2.
Notice that if we multiply Equation 2 by -3, then the b terms will be opposites. So:
[tex]-3(0)=-3(a-b+c)[/tex]
Multiply:
[tex]0=-3a+3b-3c[/tex]
Add this to Equation 1:
[tex](0+2)=(9a-3a)+(-3b+3b)+(c-3c)[/tex]
Compute:
[tex]2=6a-2c[/tex]
Again, we can divide both sides by 2:
[tex]1=3a-c[/tex]
So, we know have two equations with only two variables:
[tex]3=a+c\text{ and } 1=3a-c[/tex]
We can solve for a using elimination since the c term are opposites of each other. Add the two equations together:
[tex](3+1)=(a+3a)+(c-c)[/tex]
Compute:
[tex]4=4a[/tex]
Solve for a:
[tex]a=1[/tex]
So, the value of a is 1.
Using either of the two equations, we can now find c. Let's use the first one. Hence:
[tex]3=a+c[/tex]
Substitute 1 for a and solve for c:
[tex]\begin{aligned} c+(1)&=3 \\c&=2 \end{aligned}[/tex]
So, the value of c is 2.
Finally, using any of the three original equations, solve for b:
We can use Equation 3. Hence:
[tex]6=a+b+c[/tex]
Substitute in known values and solve for b:
[tex]6=(1)+b+(2)\\\\6=3+b\\\\b=3[/tex]
Therefore, a=1, b=3, and c=2.
Hence, our quadratic function is:
[tex]f(x)=x^2+3x+2[/tex]
An element with mass 570 grams decays by 18% per minute. How much of the element is remaining after 13 minutes, to the nearest 10th of a gram?
9514 1404 393
Answer:
43.2 grams
Step-by-step explanation:
The exponential equation for the decay can be written as ...
amount remaining = (initial amount)(1 -decay rate)^t
= 570(1 -0.18)^t
We want to find the amount remaining after 13 minutes. Evaluating this equation for t=13, we have ...
amount remaining = 570(0.82^13) ≈ 43.2 . . . grams

Answer: Image #1: C. Distributuve Property Image #2: A. n + 2(7)
Step-by-step explanation: For Image #1, they used the Distributive Property because the number 3 was (distributed) and multiplied to both x and 7. The equation is saying that 3x + 21 = 42, and that we’re trying to solve for x. For Image #2, the answer is A. n + 2(7) because after you solve the expression, the answer would be 14n. When you look at the four options, (A. B. C. D.), letter A. would be the answer because it equals to 14n.

Anthony says that the expression abc has three terms because it uses three different variables. Critique Anthony's reasoning and explain whether he is correct.
Answer:
Anthony's reasoning is incorrect
Step-by-step explanation:
The expression abc is not made up of three terms because it is just an entity. For the expression to be called a three term expression, each of the variables must be separated using mathematical signs. For example, the expression a + b + c can be referred to as three terms because each variables are separated by a plus sign. In this case they are different entity.
From the above explanation, we can conclude that Anthon's reasoning is incorrect. The expression abc is just one term not three terms.

f(x) has been
translated to the left

Answer:
f(x) has been translated to the right one and down five.
Step-by-step explanation:
Given
[tex]g(x)=f(x-1)-5[/tex]
Required
Determine the transformation
Taking the analysis one at a time
The relationship between f(x) and f(x - h) is that f(x) is translated h units to the right
So, when f(x) becomes f(x-1), it is as a result of f(x) being translated 1 unit to the right
The relationship between f(x) and f(x) - h is that f(x) is translated h units downwards
So, when f(x - 1) becomes f(x - 1) - 5, it is as a result of f(x - 1) being translated 5 units downwards.
Hence, option 2 answers the question

Melanie deposits $8200 in a bank account paying 4.4% simple interest. How much money will be in her account after 5 years and 6 months?
Answer:
8200+1894.40 = $10,094.40
Step-by-step explanation:
The formula we'll use for this is the simple interest formula, or:
I = P x r x t
Where:
P is the principal amount, $8200.00.
r is the interest rate, 4.4% per year, or in decimal form, 4.4/100=0.044.
t is the time involved, 5.5....year(s) time periods.
So, t is 5.5....year time periods.
To find the simple interest, we multiply 8200 × 0.044 × 5.5 to get that:
The interest is: $1984.40 + add to Investment ($8000) and you'll get the answer.
5-3(2x-7)=2(7-3x)
What is true for the equation x=0, x=28, the equation has no solution or the equation has infinitely many solutions
Step-by-step explanation:
Part 1: 4x + 7 = 3(2x - 5)4x+7=3(2x−5)
4x+7=6x-154x+7=6x−15
7=6x-15-4x7=6x−15−4x
7=2x-157=2x−15
7+15=2x7+15=2x
22=2x22=2x
22=2x / 222=2x/2
x=11x=11
Part 2: Sam is not correct because he messed up the second step. He added 2x on both sides to get 7x, instead he should have subtracted.
