Answer:
5×(-4) = -20
(-1) × 4 = -4
Step-by-step explanation:
Here it' sayin when a positive number ( it may be odd or even ) gets multiplied with an even number ( it may be positive or negative ) , the product will be positive number.
5×(-4) = -20 .Here 5 is a positive number & 4 is a negative even number but the product -20 is a negative number. So it contradicts the statement.
(-1) × 4 = -4 . Here -1 is a negative number & 4 is a positive even number but the product -4 is a negative number. So it contradicts the statement.
Answer:
First, you have to set 5x equal to (3x+10). They are vertical angles and therefore congruent.
5x = 3x+10 The variable should only be on one side of the equation,
5x - 3x = 10 Therefore subtract 3x from both sides
2x = 10 Divide by 2 on both sides.
x = 5
We're not done yet, since we've found the x-value we have to solve for ∠GEC.
∠GEC = 3x+10 = 3(5)+10 = 15+10 = 25°
∠GEC and ∠FEG form a right angle. This means that the sum of the two angles is 90°
90° = 25° + x In this case, we're using "x" to solve for ∠FEG
90-25 = x We subtract 25 from both sides to get the variable by itself.
65° = x
∠FEG = 65° The Answer is B

Answer:
A. How can the equation be used in temperature conversion?
You take the conversion equation C = (5/9) (F - 32) and you replace the F by the value of Fahrenheit degrees... then solve the calculations to get the degrees in Celsius.
For example, if you have 80°F to convert in °C:
C = (5/9) (80 - 32) = (5/9) (48) = 26.66 °C
B. How can you use the graph to find the body temp in C?
Using the graph will give a very imprecise measure due the scale of the graph.
But you would have to find 98.6 on the axis of X (it represents the °F), then go upwards until you find the line....
Then report that position on the line on the Y-axis (representing the °C) to get your measure.
