Which equation represents the line that passes through (0,0) and is perpendicular to y= -4/3x + 3

Answer:

Im pretty sure the the product will be less than 2 7/8.

I think the answer will be 23/72

Answer:

Its below in the explanation

Step-by-step explanation:

2^2 = 4 so y=4 and x,y = 2,4

3^2 = 9 and x,y = 3,9

4^2=16 and x,y=4,16

Please give me brainliest

Answer:

2^2 = 4 so y=4 and x,y = 2,4

3^2 = 9 and x,y = 3,9

4^2=16 and x,y=4,16

Answer:

The time it takes to boil 2.2 litres of water is approximately 141 seconds

Step-by-step explanation:

The given parameters are;

The relationship of the variables, T and A is a proportional, therefore, we have;

T ∝ A, or T/A = k = Constant of proportionality

The time it takes to boil 2.8 liters of water = 180 seconds

∴ When A = 2.8 litres, T = 180 seconds, from which we have;

k = T/A = 180 s/(2.8 L) = 450/7 s/L

k = 450/7 s/L

When A = 2.2 litres, we have;

T/A = k

∴ T = k × A

Plugging in the value for both 'k', and 'A' when A = 2.2 litres, gives;

T = k × A = 450/7 s/L × 2.2 L = 990/7 s = 141.[tex]\overline{428571}[/tex] s

The time it takes to boil 2.2 litres of water, given a direct proportionality relation is, T = 141.[tex]\overline{428571}[/tex] seconds ≈ 141 seconds given to the nearest second.

Answer:

Step-by-step explanation:

(3*5) 15+(4*5) 20

20+15= 35-15= 20

Your answer is 20 I believe.

Answer: x = 5

Step-by-step explanation:

The area of a rectangle is the length times the width. Since the dimensions are given as functions of x, youre going to have to use FOIL to combine them, then set that answer equal to the given value of 72.

l*w = (x+3)*(x+4) = x^2 + 7x +12 = 72

Subtract 72 on both sides. There is a reason why we'll do this instead of subtracting 12. The quadratic formula will help us to solve for x.

x^2 + 7x - 60 = 0

Apply the quadratic formula

[tex]\frac{-7 (+/-)\sqrt{7^2-(4)*(1)*(-60} }{2*1} =\frac{-7(+/-)17}{2}[/tex]

We cant have a negative x value because that would result in negative dimensions and a negative area, which is impossible in this context. So you want to add the 17 instead of subtracting it.

x = 5 and x = -12

An alternate way is just factoring the trinomial to:

(x+12)(x-5) = 0

Answer:

[tex]5\frac{1}{8}[/tex]

Step-by-step explanation:

5 3/4 = 23/4

(23/4)2 = 46/8

46/8 - 5/8 = 41/8 = 5 1/8

Answer:

X = 60°

Step-by-step explanation:

the angle you are looking for is a corresponding angle to the angle given (121°)

2x + 1 = 121

121 - 1 = 2x

121 - 1 = 120

2x = 120

120/2 = 60

X = 60

Answer:

[tex]4x+3y=12.35-------------1\\\\x+8y= 13..05-------------2[/tex]

Step-by-step explanation:

Given data

let bread be x

and soup be y

Kacey buys four cans of soup and three loaves of bread for $12.35

4x+3y=12.35-------------1

Fernando buys eight cans of soup and one loaf of bread for $13.05

x+8y= 13..05-------------2

Hence the equation for both of their purchase is [tex]4x+3y=12.35-------------1\\\\x+8y= 13..05-------------2[/tex]

Answer:

Answer:

20 units square

Step-by-step explanation:

do the Pythagoras theorem

a²=b²+c² ⇒ a=√b²+c²

if b is 4 and c is 2 an a is the unknown

so a=√(4)²+(2)²

a=√20

then get the rule of the area of the square

Area of the square= s²

s=a=√20 (a is the hypotenuse of the triangle and also a side in the square)

so s²=20

Area of the square=20 units square
