A media personality argues that global temperatures are not rising, because every year an increase is reported such as 0.08 degr

ees C. The difference from the previous year is less than the margin of error of about 0.15 degrees C, so that difference should be ignored. What is a strong counterargument?
Even 0.08 degrees is a lot and thus should be considered.


The margin of error is just extra information and thus can be ignored.


The difference with any previous decade is much greater than the margin of error.


0.15 - 0.08 is 0.07, which is still an increase and thus should be considered

What property is 7+(4+6)=7+n
Ket [755]

This looks like "half" a property. I'm assuming you mean something that looks like this:


IF a + b = a + c, THEN b = c. In the expression in your problem, the role of a is being played by 7. The role of b is played by (4 + 6), and the role of c is played by n.


The conclusion would be that 4 + 6 = n.


But you asked about what the property is called. The likely name is the subtraction property of equality. How did we go from a + b = a + c to the conclusion b = c? We subtracted a from both sides of the equation.

What is the slope of the line parallel to 7x + 4y = -16?
GarryVolchara [31]

Answer:

The slope of the line that is parallel to the given line is \frac{-7}{4}

Step-by-step explanation:

Parallel lines have the same slopes and different y-intercepts

The slope of the line who has an equation ax + by = c is m = \frac{-a}{b}

Let us use these rules to solve the question

∵ The equation of a given line is 7x + 4y = -16

→ Compare it with the form of the equation above

∴ a = 7 and b = 4

∵ The slope of the line = \frac{-a}{b}

∴ The slope of the line = \frac{-7}{4}

∵ Parallel lines have the same slope

∴ The slope of the line that is parallel to the given line is \frac{-7}{4}

A student says that the slope pf the line for the equation y=20-15x is 20 and the y-intercept is 15. Find and correct the error.
Alla [95]
We have this equation for the slope is: y=mx+b which m is the slope and b is the y-intercept, so we have y=20-15x or y=-15x+20, and we already know that the slope is -15 and y-intercept is 20. As a result, the student's error is that he thinks that 20 is the slope because it is the first number. Hope it help!

in three plays of a football game, there is a gain of 4 yards, a loss of 9 yards, and a gain of 15 yards. What number can you us
Aloiza [94]

We can use minus(-) sign i.e. -9 to represent loss of 9 yards.

<h3>Write the difference between gain and loss.</h3>

The word “gain” implies “acquiring something”.

Gain means to acquire something one desires especially because of one’s efforts.

Gain means to get something additional, for example, to gain more speed, to gain more weight.

We can denote gain by using plus(+) sign before the given number.

“Loss” generally means “to lose something one already has.”

Loss means the deprivation from keeping something, for example, bearing the loss of a theft.

It refers to something which is lost, for example, the theft of jewelry was a great loss.

We can denote loss by using minus(-) sign before the number.

In the given question it is said that there is gain of 4 yards, loss of 9 yards and gain of 15 yards.

It is asked that how would we represent 9 yards loss.

We know that we use minus(-) sign to represent loss.

So we can represent loss of 9 yards by writing it as -9.
