Ok, so first we must understand what the slope of a line actually is. The slope, or gradient, is the value by which y increases (or decreases, if this is negative) for each increase of one unit in the x-value. So basically what you should think about for this question is, as x increases, does y decrease, increase or stay the same?

From the graph, we can see that as the value of x gets larger, the value of y also increases, therefor the slope is positive.

For the other answers:

If the slope were negative, we would see that the y-values would get smaller as x would get bigger.

If the slope was zero, you would see a horizontal line; this means that there is no change in the y-value as x-increases.

If the slope was undefined, you would see a vertical line; this is an extreme case where you cannot say how much y increases by as the line continues till infinity, therefor we say that it is undefined.

2) Simplify 675 divided by (6+9 divided by 3)=
Sindrei [870]

Remember PEMDAS. First thing you do is the parentheses. Division is always before addition. 9 divided by 3 = 3. 6 + 3 = 9 Now 675 divided by 9. The answer to that question is 75. You should show your work.

What is the value of x?<br><br> Please answer ASAP
Komok [63]

Answer:

x = 5

Step-by-step explanation:

You have a right triangle, so you can use the Pythagorean Theorem.

a^2 + b^2 = c^2

x^2 + 12^2 = 13^2

x^2 + 144 = 169

x^2 = 25

x = 5

Answer: x = 5

Please help :( it doesnt make any sense​
melomori [17]
I’m guessing that x is the angle on the right that isn’t shown?
Anyways if that’s the case then:

We know that the sum of all the angles of a triangle add up to 180 degrees.
In this triangle we know that one angle is 55 degrees and the other is 90 degrees, so to find the last angle we do the sum of all the angles and we remove the 2 angles:

180- (55+90)= 35 degrees.

x= 35 degrees

What is the probability of a coin being tossed 7 times and landing on all heads?
mote1985 [20]
A tree diagram can be drawn for a clearer understanding. The branches of the tails can be ignored since we are not concerned about that. To find the probability along the branches, we just have to multiply the probabilities of each branch, giving you an answer of 1/128
