Answer:
y = 18
Step-by-step explanation:
Just let x = 12
y = 6 + x
y = 6 + 12
y = 18
When x = 12, y = 18.
The graph is included to show you what y = 6 + x looks like and it also shows the point (12,18) = (x,y)
Solve the following system using the addition method:
-27x + 6y = -21
-12x +3y = -9
(3 points, 2 for work, 0.5 for each part of the solution (x,y))
Answer:
(x, y) = (1, 1)
Step-by-step explanation:
[tex] -27x + 6y = -21 [/tex] --- (1)
[tex] -12x +3y = -9 [/tex] --- (2)
Multiplying (2) by -2 to get:
[tex] 24 x - 6 y = 1 8 [/tex] --- (3)
Adding (1) and (3) to get:
[tex]-27x + 6y = -21[/tex]
[tex]24x-6y=18[/tex]
------------------------------------
[tex]-3x=-3[/tex]
x = 1
Finding y:
[tex]-12(1) +3y = -9[/tex]
[tex]3y=-9+12[/tex]
[tex]3y=3[/tex]
y = 1
Therefore, (x, y) = (1, 1).
(X,Y)= (1,1)

Given that (0,3) is on the graph of f(x), find the corresponding point for the function f(x)-2
Answer:
(0 , 1)
Step-by-step explanation:
given y = f(x), then
y = f(x) + c is a vertical translation
• If c > 0 then vertical shift up of a units
• If c < 0 then vertical shift down of a units
here c = - 2, hence shift down of f(x) by 2 units
(0, 3) → (0, 3 - 2 ) = (0, 1)

solve the inequality |2h-3| >1
Answer:
[tex]\large\boxed{h>2\ \vee\ h<1\to h\in(-\infty,\ 1)\ \cup\ (2,\ \infty)}[/tex]
Step-by-step explanation:
[tex]|2h-3|>1\iff2h-3>1\ \vee\ 2h-3<-1\qquad\text{add 3 to both sides}\\\\2h>4\ \vee\ 2h<2\qquad\text{divide both sides by 2}\\\\h>2\ \vee\ h<1\to h\in(-\infty,\ 1)\ \cup\ (2,\ \infty)[/tex]
The solution of the absolute value inequality |2h-3| > 1 is h > 2 or h < 1. Two cases are considered based on whether the expression inside the absolute value is greater than 1 or less than -1.
Explanation:To solve the inequality |2h-3| > 1, you need to consider two cases because an absolute value inequality represents two separate inequalities.
Case 1: The expression inside the absolute value (2h-3) is greater than 1. This gives us the inequality 2h - 3 > 1. Solving for h, we get h > 2.
Case 2: The expression inside the absolute value (2h-3) is less than -1. This gives us the inequality 2h - 3 < -1. Solving for h, we get h < 1.
Thus, the solution of the absolute value inequality is h > 2 or h < 1.

Step-by-step explanation:
Graph both functions to find the solution(s) to the system. {f(x)=x+1 g(x)=x2−6x−7 Use the line tool to graph the line. Use the parabola tool to graph the parabola. Choose maximum or minimum point first and then a point on the parabola.
Answer:
solutions to f(x)=g(x) are x=-1 and x=8
Step-by-step explanation:
The minimum point of the parabola will be found at ...
x = -b/(2a) . . . . . where a, b, c are the coefficients of ax²+bx+c
For g(x) = x² -6x -7, the minimum will be at x=-(-6)/(2·1) = 3. The minimum value is ...
g(3) = 3² -6·3 -7 = -16
so the vertex (minimum point) you want to plot is (3, -16). Since the coefficient of x² is 1, there is no vertical scaling, so when the value of x differs from 3 by 1 unit, the value of g(x) will be 1² = 1 unit higher. That is, g(4) = -15, so (4, -15) is another point on the parabola.

Sebastian wanted to order pizzas for $7 each. The delivery charge is $3.50. He has $20.
What is the correct solution for how many pizzas he could order?
Answer: 2 pizzas with 2.50 left
Step-by-step explanation: First you subtract the 3.50 from the 20, that'll leave you with 16.50 and then from there you subtract 7 from it until you can't anymore
Division is a method of distributing a group of things into equal parts.
According to the given question, we have the following data:
Sebastian has a total of $20.He wanted to order pizzas for $7 each.The delivery charge is $3.50So, first of all, we have to pay the delivery charge whether we are ordering a single or bulk. That's why we have to deduct that from the total Sebastian has.
$20 - $3.50 = $16.50
So, now Sebastian has $16.50.
Now, each pizza is for $7.
So, it's clear now that, Sebastian has to divide his total amount by the price of each pizza to get how many pizzas he can order.
Number of pizzas Sebastian can order = (Total amount Sebastian has / price of each pizza)
= ($16.50 / $7)
= 2.36
But wait how can he order a fraction of pizzas so we have to take 2 as our answer.
Therefore, Sebastian could order a total of 2 pizzas.

thomas want to save money for a vacation. thomas invest 1,200 in account that pays an interest rate of 4% how many years will it take for the account to reach 14,400. round to the nearest hundredth
Answer:
63.36 years
Step-by-step explanation:
This is a compound interest problem and the following information has been provided;
Principal, P = 1200
Interest rate, r = 4%
Accumulated amount, A = 14400
We are required to determine the number of years for the principal to accumulate to the given amount. We use the compound interest formula;
[tex]A=P(1+r)^{n}[/tex]
We substitute the given values into the formula and solve for n;
[tex]14400=1200(1+\frac{4}{100})^{n}\\12=(1.04)^{n}\\[/tex]
The next step is to introduce natural logarithms;
[tex]ln12=nln(1.04)\\n=\frac{ln12}{ln1.04}\\n=63.36[/tex]
Thomas has invested $1,200 at a 4% interest rate. Using the formula for compound interest and solving for time, it will take approximately 29.1 years for his account balance to reach $14,400.
Explanation:Thomas has invested an amount of $1,200 into an account with a 4% interest rate. This type of problem involves the use of the formula for compound interest. The general formula for compound interest is: A = P(1 + r/n)^(nt), where:
A is the amount of money accumulated after n years, including interest. P is the principal amount (the initial amount of money). r is the annual interest rate (in decimal). n is the number of times that interest is compounded per year. t is the number of years the money is invested for.
In this case, we assume the interest is compounded annually, so n = 1. We rearrange the formula to solve for t, giving us the formula t = log(A/P) / log(1 + r).
Substituting the given values into the formula, we get t = log(14400/1200) / log(1 + 0.04), which gives a result of approximately 29.1 years. So, it will take around 29.1 years for the account balance to reach $14,400.

HELP: Solve this problem and show how you thought of it 3 different ways: 1/3 ÷ 5 (24 pts)
Three methods to solve the equation are Division as Repeated Subtraction,Using Fraction Division Formula,Using Decimal Conversion.
I'll approach this problem using three different methods:
Method 1: Division as Repeated Subtraction
Dividing [tex]\( \frac{1}{3} \)[/tex] by 5 means finding out how many times 5 can be subtracted from 1/3
[tex]\( \frac{1}{3} - 5 = - \frac{14}{3} \)[/tex]
So, you can subtract 5 from 1/3 approximately 0 times with a remainder of [tex]\( - \frac{14}{3} \).[/tex]
Method 2: Using Fraction Division Formula
To divide a fraction by a number, you can multiply the fraction by the reciprocal of the number.
[tex]\( \frac{1}{3} \div 5 = \frac{1}{3} \times \frac{1}{5} \)[/tex]
[tex]\( \frac{1}{3} \times \frac{1}{5} = \frac{1 \times 1}{3 \times 5} \)[/tex]
[tex]\( \frac{1}{3} \div 5 = \frac{1}{15} \)[/tex]
So, [tex]\( \frac{1}{3} \div 5 = \frac{1}{15} \).[/tex]
Method 3: Using Decimal Conversion
Converting 1/3 to a decimal gives [tex]\( 0.3333... \)[/tex]
Then, dividing 0.333 by 5 gives:
[tex]\( 0.3333... \div 5 \approx 0.0667 \)[/tex]
So, [tex]\( \frac{1}{3} \div 5 \approx 0.0667 \).[/tex]
These are three different ways to solve the problem [tex]\( \frac{1}{3} \div 5 \).[/tex]
