If you wanted an output of 7 for the rule y= -x+4, what would you need as an input?

Answers

Answer 1

y is output
if y=7 find x

7=-x+4
minus 4 both sides
3=-x
times -1
-3=x

your input will be -3

Answer 2

Final answer:

To get an output of 7 in the equation y = -x+4, the input value needed is -3.

Explanation:

To obtain an output of 7 for the linear equation y = -x + 4, we need to find the appropriate input value (x). The equation represents a straight line in the Cartesian plane, where 'y' is the dependent variable, and 'x' is the independent variable.

To solve for 'x' when y = 7, we simply substitute 7 for 'y' in the equation:

7 = -x + 4

Now, we need to isolate 'x' on one side of the equation. To do this, we can move the constant term (4) to the other side of the equation by subtracting it from both sides:

7 - 4 = -x

This simplifies to:

3 = -x

To solve for 'x', we multiply both sides by -1 to get:

x = -3

So, if you input x = -3 into the equation y = -x + 4, you will indeed get an output of 7:

y = -(-3) + 4

y = 3 + 4

y = 7

Therefore, an input of x = -3 will yield an output of 7 for the given equation.

determine translation

Answers

The translation moved point B(-5, -2) to B'(6, -5). Although a graph isn't necessary, it helps visualize what happened.

What happened to the x-coordinate of B? It changed from -5 to 6, an INCREASE of 11. So point B moved 11 units to the RIGHT.

What happened to the y-coordinate of B? It changed from -2 to -5, a DECREASE of 3. So point B moved 3 units DOWN.

A mechanic repairs Mr. Estes car the amount for parts is $48 and the rate for the mechanic is $40 per hour. Write and solve an equation to find the total cost of repairs to Mr. Estes car if the mechanic works for 1.5 hours

Answers

y = 48 + 40h....where y is the total cost and h is the number of hrs worked

so if he worked 1.5 hrs....h = 1.5

y = 48 + 40(1.5)
y = 48 + 60
y = 108 <===

Final answer:

To calculate the total cost of repairs to Mr. Estes's car, add the fixed cost of parts ($48) to the labor cost ($40 per hour for 1.5 hours), resulting in a total cost of $108.

Explanation:

To find the total cost, we need to consider both the fixed cost (cost of parts) and the variable cost (mechanic's labor charged per hour).

The fixed cost for parts is $48, and the mechanic charges $40 per hour.

If the mechanic works for 1.5 hours, we can calculate the total cost using the equation:

Total Cost = Cost of Parts + (Hourly Rate × Hours Worked).

Substituting the given values into the equation, we get:

Total Cost = $48 + ($40 × 1.5)

= $48 + $60

= $108

Therefore, the total cost of repairs to Mr. Estes's car is $108.

a farmer made a square chicken coop with a length of 6 and a half metres. determine the area of the chicken coop

Answers

Final answer:

The area of the chicken coop is 42.25 square meters

Explanation:

To determine the area of the chicken coop, we need to know the length of one side of the square. In this case, the length is given as 6 and a half meters. To find the area of a square, we square the length of one side. So, in this case, the area of the chicken coop is (6.5) * (6.5) = 42.25 square meters.

The process involves squaring the length of one side of the square to find the area. This fundamental formula is applicable not only to squares but also to rectangles, where the area is calculated as the product of the length and width. Understanding these basic geometric principles allows for accurate measurements and calculations in various real-world scenarios, such as determining the area of structures like the chicken coop in your example.

7.24 divided by 7 rounded to the nearest tenth

Answers

Final answer:

To divide 7.24 by 7 and round to the nearest tenth, you divide 7.24 by 7, which gives you approximately 1.034285714. The final answer, rounded to the nearest tenth, is 1.0.

Explanation:

To divide 7.24 by 7 and round to the nearest tenth, we divide 7.24 by 7, which gives us approximately 1.034285714. To round to the nearest tenth, we look at the digit in the hundredths place, which is 4. Since 4 is less than 5, we do not round up. Therefore, the final answer, rounded to the nearest tenth, is 1.0.

Final answer:

The division of 7.24 by 7 results in 1.0342857. Rounding this to the nearest tenth, considering the value in the hundredths place is less than 5, the final answer is 1.0.

Explanation:

The question of 7.24 divided by 7 rounded to the nearest tenth deals with basic division and rounding numbers. When you divide 7.24 by 7 using a calculator, you get 1.0342857. To round this to the nearest tenth, we look at the number directly after the tenths place, which is 3 (in the hundredths place). Since 3 is less than 5, we do not round up. Therefore, the answer is 1.0 when rounded to the nearest tenth.
