Answers

Answer 1

Answer:

Step-by-step explanation:

Let's solve your equation step-by-step.

(y+4)(3y−5)=0

Step 1: Simplify both sides of the equation.

3y2+7y−20=0

Step 2: Factor left side of equation.

(3y−5)(y+4)=0

Step 3: Set factors equal to 0.

3y−5=0 or y+4=0

y=5 /3

or y=−4

y is directly proportional to x and y=10 when x=4 find the formula connecting y and x and find y when x=8​

Answers

X=5
Explanation
The initial statement is y♾1/x
To convert to an equation multiply by k the constant of variation
Y=k x 1/x =k/x
To find k use the given condition
Y=10 when x=4
Y=k/x —k= yx =10x4 =40
Equation is y =40/x
When y =8
X= 40/y =40/8 =5

What is the difference between a reactant and a product in a chemical equation? (Science question)

Will it be positive or negative? Why?​

Answers

answer is -8
why ? Because there’s only a number that’s negative so if one number is negative then the answer is gonna be negative
Ok so (-2)^3 means -2 x -2 x -2

Now -2 x -2 = 4
Because minus into minus is plus

4 x -2 = -8
Because minus into plus is minus

Therefore, we can see that -2 x -2 x -2 = -8

Which is the same as saying (-2)^3 = -8

Question: Find the measurement indicated in each parallelogram

Answers

31.) Answer: 11
32.) Answer: 14
33.) Answer: 30.6
34.) Answer: 16.5

Answer:

31) 11

32) 14

33) 30.6

34) 16.5

Step-by-step explanation:

31) GW is half the length of UW and UW is equal to 22. So, 22/2 = 11

32) VY is half the length of VX and VY is equal to 7. So, 7 x 2 = 14

33) VR is half the length of VX and VR is equal to 15.3. So, 15.3 x 2 = 30.6

34) UH is half the length of FH and FH is equal to 33. So, 33/2 = 16.5

A rectangle has a perimeter of 600 cm. The width of the rectangle is 40 cm less than the length. What is the length of the rectangle, in cm?

Answers

Answer:

170cm

Step-by-step explanation:

Given data

perimeter of 600 cm

let the Length be x

L=x

W= x-40

P=2L+2W

600=2(x)+2(x-40)

600=2x+2x-80

600= 4x-80

600+80= 4x

680= 4x

divide both sides by 4

x= 680/4

x=170

Hence the length is 170cm
