Each time the line makes a “stop” at an intersection of graph lines, make a point. Count how many it takes to go up and across from one point to another. Think of it as a fraction: top number is how many it takes to go up, bottom number is how many it takes to go across. If top number is going up, then it is positive. If it is going down, it is a negative number. So the answer is STEEPEST slope is 2, LEAST steep is 1/5, and the MIDDLE one is 1.

Which best explains whether a triangle with side lengths 5 cm, 13 cm, and 12 cm, is a right triangle?

Llana [10]

The Pythagorean Proposition can help you explain this:
${a}^{2} = {b}^{2} + {c}^{2} \\ {13}^{2} = {5}^{2} + {12}^{2} \\ 169 = 25 + 144$

Combine like terms. y + 3 + 9(y + 5) =

Mnenie [13.5K]

Answer:

The answer is 10y + 48.

Step-by-step explanation:

First you have to get rid of brackets by expanding :

$y + 3 + 9(y + 5) \\ = y + 3 + 9y + 45$

Next you have to collect like-terms :

$y + 3 + 9y + 45 \\ = 10y + 48$

Step-by-step explanation:

To start, we know that the initial boiling point is 212 degrees F. For every 1 added to E, the boiling point decreases by 2. So, we havethe equation 212 - 2E or -2E + 212 = b or D).

Suppose that grade point averages of undergraduate students at one university have a bell-shaped distribution with a mean of 2.6

sergey [27]

Answer:

Below.

= 99.7%

= 100 - 99.7%/2

= 0.3/2

= 0.15%

100% - 0.15%

= 99.85%

100 POINTS FOR ANYONE WHO CAN ANSWER THESE! <3

faust18 [17]

Answer:

∠1 = 142°

reason: angles 1 and 2 are supplementary so they equal 180. 180-38 is 142

∠3 = 38°

reason: angles 2 and 3 are adjacent angles because they are diagonal from each other so they will equal the same measure.

∠4 = 142°

reason: since angle 4 is adjacent to angle 1 and is supplementary to angle 3, it has to be 142

∠5 = 38°

reason: since it is a transversal that means both of the intersections are the same measurements. so angle 5 is 38 since it matches up with angle 2

∠6 = 142°

reason: for the same reason as angle 5. angle 6 matches up with angle 1 so it has to equal 142.

∠8 = 142°

reason: since angle 8 is adjacent to angle 6 it has to equal 142. angle 8 is also a transverse angle to angle 4. and since angle 4 also equals 142, 8 has to also
