-6y^3+7y^2-2

Step-by-step explanation:

(-2y^3+2y^2-9)+(-4y^3+5y^2+7)

-2y^3-4y^3+2y^2+5y^2-9+7

-6y^3+7y^2-2

Answer:

$25.60

Step-by-step explanation:

To find how much money will be donated, we find how many 0.25's there are in 16 and multiply that by $0.40.

16/0.25=64

64*0.4=25.6

$25.60

Answer:

a complete metamorphosis undergoes four stages while an incomplete metamorphosis undergoes three stages skiping the larva stage

Answer:

The explanation is given below:

Step-by-step explanation:

The computation is shown below:

If we add 7 and 2 then it provides 9 and then subtract 2 from 9 it provides 7 and then subtract 7 from 9 it provides 2 and like this way it follows for others two

7 + 2 = 9

9 - 2 = 7  

9 - 7 = 2

8 - 3 = 5  

5 + 3 = 8

8 - 5 = 3

3 + 7 = 10  

10 - 7 = 3  

10 - 3 = 7

Answer:

The constant of  proportionality is 7.87.

Step-by-step explanation:

The relation between x and y is given by the equation :

y = 7.87x

y is directly proportional to x i.e.

y ∝ x

To remove the constant of proportionality, a constant 7.87 is inserted. Hence, the constant of  proportionality is 7.87.

Answer:

The jellyfish travels faster than the walrus

Step-by-step explanation:

Given data

A jellyfish travels 3/5 mile in 1/6 hour

Distance= 3/5 mile

time= 1/6 hour

speed= distance/time

speed= 3/5/1/6

speed= 3/5*6/1

speed= 18 mile per hour

a walrus travels 5/6 mile in 3/10 hour.

Distance= 5/6 mile

time= 3/10 hour.

speed= distance/time

speed= 5/6/3/10

speed= 5/6*10/3

speed= 50/18 mile per hour

Answer:
the first answer is 3 3/5
the second answer is 2 7/9
the third answer is “greater than” and then “jellyfish”

Answer:

c) (-3, 1)

Step-by-step explanation:

It's the only point that is not on the border of the graph.

The point could confirm the graph is shaded correctly is (-3, 1)

The correct option is (C).

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given:

[tex]\frac{\left(x\ +3\ \right)^{2}}{1}\ +\ \frac{\left(y-2\right)^{2}}{9} > 1[/tex]

As, per the graph attached below we can see that the small part is not shaded other than that part whole part is shaded.

Hence, the point could confirm the graph is shaded correctly is (-3, 1).

Answer:

-3 [tex]\frac{4}{5}[/tex] = -3 [tex]\frac{4}{5}[/tex]

Step-by-step explanation:

Add up the numbers on either side of the equal sign.  If it helps, you can convert everything to improper fractions so that the math is easier.

[tex]\frac{17}{5} +(-\frac{36}{5} )= -\frac{19}{5}, or -3\frac{4}{5}[/tex]

Answer: y = 3x -2

Slope =3

Y-intercept = -2

Step-by-step explanation:

2y+8 = 6x + 4

Subtract 8 on both sides.

2y = 6x -4

Divide by 2. 2y divided by 2 leaves just y. 6x divided by 2 is 3x. -4 divided by 2 is -2.

Answer:

sin; 7.7

Step-by-step explanation:

✔️Reference angle = 50°

Length of side opposite to reference angle = b

Hypotenuse = 10

✅The trigonometric function to use is sin

✔️To find b (opp), we would use:

Sin 50 = opp/hyp

Sin 50 = b/10

10 × sin 50 = b

b = 7.66044443 ≈ 7.7 (nearest tenth)
