Answer:

Top left: a is negative and p is positive

Step-by-step explanation:

The formula y = ax + p is referring to the formula y = mx + b where m is the slope and b is the y-intercept.

Since the line is going down, the slope is negative-- a is negative.

Since the line crosses the y-axis above the origin, the y-intercept is positive-- p is positive.

Answer:

a is negative and p is positive

Step-by-step explanation:

The equation y = ax + p is written in slope-intercept form, where a is the slope and p is the y-intercept.

When a slope is negative, the line goes down the further right it goes.

The line on the graph lowers as it moves right, which means that the slope(a) is negative.

The line intercepts the y-axis above the origin, which means that it must be positive.

Answer:

a triangle with side measurements of 5, 5, and 5 inches​

Step-by-step explanation:

I took the test.

Construction of triangle with side measurement 2 inch, 3 inch, 5 inch is not possible.

This theorem simply states that the sum of two sides of a triangle must be greater than the third side. If this is true for all three combinations, then you will have a valid triangle.

If triangle has the sides, a ,  b and c then

a + b > c

b + c > a

a + c > b

Given length of the sides,

a)  Triangle made with sides having length 3 inch, 4 inch, 6 inch.

3 + 4 > 6 ; 4 + 6 > 3 ; 3 + 6 > 4

= 7 > 6 ; 10 > 3 ; 9 > 4

Triangle inequality theorem is satisfied, hence triangle construction is possible

b)  Triangle made with sides having length 2 inch, 3 inch, 5 inch.

2 + 3 > 5 ; 3 + 5 > 2 ; 2 + 5 > 3

= 5 = 5 ; 8 > 3 ; 7 > 3

Triangle inequality theorem is not satisfied, hence triangle construction is not possible

a)  Triangle made with sides having length 3 inch, 3 inch, 4 inch.

3 + 3 > 4 ; 3 + 4 > 3 ; 3 + 4 > 3

= 6 > 4 ; 7 > 3 ; 7 > 3

Triangle inequality theorem is satisfied, hence triangle construction is possible

a)  Triangle made with sides having length 5 inch, 5 inch, 5 inch.

5 + 5 > 5 ; 5 + 5 > 5  ; 5 + 5 > 5

= 10 > 5 ; 10 > 5 ; 10 > 5

Triangle inequality theorem is satisfied, hence triangle construction is possible.

Hence, Triangle with side measurements of 2 inch , 3 inch , and 5 inch is not possible to construct.

Answer:

7.8%

Step-by-step explanation:

Answer:

The percentage of increase is 37%

Step-by-step explanation:

The way to find the percentage of increase is to divide The difference between the two numbers by the number before the increase

7.8 - 5.7 = 2.1

The difference between 7.8 and 5.7 is 2.1

So now we divided 2.1 by the number before the increase, in this case, 5.7

2.1 ÷ 5.7 = 0.3684

0.3684 rounded to the nearest hundredth is 0.37

Thus the percentage of increase is 37%

Answer:

0.25 pints

Step-by-step explanation:

To find how many pints they ate, find the number of pints in half a cup.

In 1 cup, there are 0.5 pints.

This means in half a cup, there will be 0.25 pints.

So, Gio and his friends ate 0.25 pints

Answer:

x = 16

Step-by-step explanation:

step 1 - 64 + 100 + x = 180 (all triangles equals 180)

step 2 - 164 + x = 180

step 3 - 164 + x = 180

-164. -164

step 4 - 180 - 164 = 16

step 5 - 100 + 64 + 16 = 180

(I do this part to double check my work)

step 6 - x = 16

The number 8 divided by 3 is 2 with a remainder of 2 (8 / 3 = 2 R.

Answer:

The steps are more or less the same, except for one new addition:

Divide the tens column dividend by the divisor.

Multiply the divisor by the quotient in the tens place column.

Subtract the product from the divisor.

Bring down the dividend in the ones column and repeat

Step-by-step explanation:

The number 8 divided by 3 is 2 with a remainder of 2 (8 / 3 = 2 R.

Answer:

The wing of the dragonfly was 9.65 cm longer than that of the fly, 102% larger in percentage terms.

Step-by-step explanation:

Since the length of the wing of the old dragonfly was 19.5 cm, while the length of the wing of a common fly is 9.85 cm, to determine how long the dragonfly's wing was compared to that of the fly, the following must be done calculations:

19.5 - 9.85 = X

9.65 = X

Thus, the wing of the dragonfly was 9.65 cm longer than that of the fly. In turn, in terms of percentages, the result is the following:

9.65 = 100

19.5 = X

19.5 x 100 / 9.65 = X

1950 / 9.65 = X

202 = X

Thus, in percentage terms, the dragonfly's wing was 102% larger than that of the current fly.

Answer:

Step-by-step explanation:

No. If two sides are 5cm the third side must be less than 2(5)=10cm

Answer: No, a triangle cannot be formed with these side lengths.

=========================================================

Explanation:

Recall that the triangle inequality theorem says that for a triangle to be possible, the sum of any two sides must be larger than the third side.

With these given side lengths, we can see that 5+5 = 10 is not larger than 20, so a triangle is not possible here. I recommend you try it out with 3 slips of paper of these lengths. You should find that the two 5 cm sides are too short to be able to connect to the 20 cm side properly.

Step-by-step explanation:

Answer:

Step-by-step explanation:

0.28 is roughly the same as 0.280, which has 3 significant digits (same as 0.205 has 3 significant digits).  It's easier when we compare numbers having the same number of decimal places.

Comparing 0.280 to 0.205, we see that the hundredths place of 0.280 (which is 8) is greater than the hundredths place of 0.205 (which is 0).  Thus 0.28 is greateer than 0.205.

alright my friend i've gotta go but i think you can solve these on your own.

just use the number that's on the Y vertical line to find y-int

and then use 2 points and count up to find the rise and then count across to fine thet run.

use the formula y=mx+b

good luck my friend <3

Answer:

Step-by-step explanation:
