The question is an illustration of simple interest.

The equation that relates Barry's savings after t years is; [tex]f(t)=1300 + 28.6t[/tex]

The given parameters are:

[tex]P = 1300[/tex] --- the amount deposited

[tex]r = 2.2\%[/tex] --- annual interest

So, the interest is calculated using:

[tex]I = PRT[/tex]

This gives

[tex]I = 1300 \times 2.2\% \times t[/tex]

[tex]I = 28.6 \times t[/tex]

[tex]I = 28.6t[/tex]

So, the equation that relates Barry's savings after t years is;

[tex]f(t)=P + I[/tex] --- i.e. the amount deposited plus the interest

This gives

[tex]f(t)=1300 + 28.6t[/tex]

Hence, the required equation is: [tex]f(t)=1300 + 28.6t[/tex]

Step-by-step explanation: Tell Maria to do the problem again.

If Maria added 45,273 and 35,687 and got a sum of 70,960 : Yes, Maria's answer is reasonable.

When we add 45,273 and 35,687 we have:

45,273 + 35,687 = 80,960

Maria's response, however, is 70,960, which is 10,000 below the accurate total. This indicates that Maria most likely added incorrectly.

The rationality of the response is demonstrated by the fact that Maria's answer is considerably less than the right answer. This 10,000-difference discrepancy is not a trivial error and suggests that an addition error most likely occurred.

Step-by-step explanation:

Reflection in the y -axis:

The rule for a reflection over the y-axis is (x, y) → (−x, y).

P (7, -4) → P' (-7, -4)

Q (-7, -8) → Q' (7, -8)

Answer:

Rate of change = 2

Step-by-step explanation:

The rate of change is equivalent to the slope of the line !

A line is written:

y=mx+b

"m" is the slope, and "b" is the y-intercept !

The line you gave was "y=2x+100"

The slope, or "m," in your equation, would be 2 !

Answer:

y= -1/5x + 1

Step-by-step explanation:

When looking for a line between two points, you want to use the following formula: (y2-y1)/(x2-x1) which finds your distance between points for the y and x coordinate to solve for your slope. y1 is the y coordinate from the first given point and x1 is the x coordinate from the first given point as well. this would go the same for x2 and y2 for the second given equation.

Next, we plug in our values so that we get (-1-2)/(10-(-5)). This will then lead us with -3/15 which simplifies to -1/5. This is our slope. Now that we have our slope we can rule out every option except the first for the answer. However, if we want to look for the entire answer we need to plug in one of our given values in the formula we have: y=-1/5x.

So to find the y-intercept, we can plug in any of the given coordinates so we can fo (10,-1) so that -1=-1/5(10)+b (b what added because we are putting the equation in slope-intercept, therefore we need to find the value b.) So we are left with -1=-2+b now we want to isolate b by adding 2 on both sides to cancel -2 and get 1=b. This would leave us with the equation y=-1/5x+1.

Answer: Answer: x> -2/11

Step-by-step explanation: Multiply both sides of the inequality by the least common denominator: 2 (-5/2(3x-2))<2x6-2x2x

Reduce the expression to the lowest term: -5(3x-2)<2 x 6-2 x 2x

Apply Multiplicative Distribution Law: -15x + 10< 2 x 6 -2 x 2x

Multiply the monomials:-15x + 10< 2 x 6 - 4x

Calculate the product or quotient: -15x + 10<12-4x

Rearrange unknown terms to the left side of the equation: -15x + 4x< 12 - 10

Combine like terms: -11x < 12 - 10

Calculate the sum or difference: -11x<2

Divide both sides of the inequality by the coefficient of variable: x > 2 ÷(-11)

Rewrite as fraction: x> 2/-11

Rewrite the fraction: x> -2/11

Answer: x> -2/11

The solution to the inequality is x>-2/11.

The given inequality is -5/2 (3x-2)<6-2x

We need to simplify the given inequality step by step.

To solve an inequality, isolate the variable on one side with all other constants on the other side. To accomplish this, perform opposite operations to manipulate the inequality. First, isolate the x by multiplying each side by two. Whatever you do to one side you must also do to the other side.

Now, multiply both sides of the inequality by 2.

That is,  -5(3x-2)<2(6-2x)

=-15x+10<12-4x

Add both sides of the inequality by 4x.

That is, -15x+10+4x<12-4x+4x

=-11x+10<12

Subtract 10 on both sides of the inequality.

That is, -11x+10-10<12-10

-11x<2

Divide both sides of the inequality by -11.

x>-2/11

Therefore, the solution to the inequality is x>-2/11.

Answer:

Step-by-step explanation:

It is a simple matter of subtracting 1 from the given x value. For example, when x=3 we need to subtract 1 away from it to find f(x); so, f(x)=2.

Side note: the term "f(x)" means "y", so when plotting this information on a graph, you will use the f(x) column as your y value.

Hint :- The point slope form of the line is [tex] m(x-x_1) = y - y_1[/tex] , where [tex](x_1,x_2)[/tex] is the point and [tex] m [/tex] is the slope of the line .

Solution :- The given point is [tex](2,-1)[/tex] and the slope is 3 . On using the point slope form of the line, we have ;

[tex]\implies m(x-x_1)=y-y_1[/tex]

Substitute ,

[tex]\implies 3(x -2) = y -(-1) [/tex]

Simplify ,

[tex]\implies 3x -6=y+1 [/tex]

Add -1 and -y to the both sides ,

[tex]\implies \boxed{3x -y -7=0 }[/tex]
