Answer:

6/4

Step-by-step explanation:

ratio of x to y is the slope so

you can use butterfly method/cross multiply (multiply numerator on one side to the denominator on the other to bring all the terms up and then solve for y)

4(y+3)=6(x+2)

4y+12=6x+12

y=6/4x

so it would be 6/4

Simplify the following expression. 3x4 +2x3 - 5x2 + 4x2 +6x-2x - 3x4 + 7 x - 3x3

vlada-n [284]

**I want to mention that please use asterisk (*) symbol for multiplication as multiplication symbol x and variable x look the exact same

Your question is

3*4+2*3-5*2+4*2+6x-2x-3*4+7x-3*3

First calculate each term getting

=12+6-10+8+6x-2x-12+7x-9

Now combine like term which means adding all of the constant together and all of the term containing variable x together

=11x-5

Therefore 11x-5 is the answer to the expression.

1. Solve for p

DerKrebs [107]

Answer:

$1. \quad p=\dfrac{-3q}{2}\\\\2. \quad b=\dfrac{4a+7}{2}, b=\dfrac{19}{2}\\\\3. \quad r=\dfrac{d}{t}\\\\4. \quad \text{D. 30}$

Step-by-step explanation:

1. Subtract p:

3p +3q -p = 0

2p +3q = 0 . . . . collect terms

2p = -3q . . . . . . subtract 3q

p = -3q/2 . . . . . . divide by the coefficient of p

2. Add 7 and divide by the coefficient of b:

4a +7 = 2b

(4a +7)/2 = b

Substitute for a to find the value of b.

(4(3) +7)/2 = b = 19/2

3. Divide by the coefficient of r:

r = d/t

4. The sum of length and width is half the perimeter:

15 + w = 90/2 = 45

w = 30 . . . . . . . subtract the length; the width is 30 units

Find the counterexample to one of the following statements

Alisiya [41]

Answer:

1) You know that the addition of all interior angles of a triangle always should add up to 180°

Then, for example, we can construct a triangle with angles

100°, 40°, 40° such that

100° + 40° + 40° = 180°

So we have an example of a triangle that has one angle greater than 90°.

2) Suppose that we have the positive numbers 0.5 and 1.

The product is: P = 0.5*1 = 0.5

the sum is: S = 0.5 + 1 = 1.5

The sum is greater than the product.

2x³-8=0 How do I solve this problem ?

wlad13 [49]

Answer:

$x=2^{\frac{2}{3}}$

Step-by-step explanation:

1) Add 8 to both sides.

$2x^3=8$

2) Divide both sides by 2.

$x^3=\frac{8}{2}$

3) Simplify $\frac{8}{2}$ to 4.

$x^3=4$

4) Take the cube root of both sides.

$x=\sqrt[3]{4}$

5) Rewrite 4 as 2².

$x=\sqrt[3]{2^2}$

6) Use this rule: ${({x}^{a})}^{b}={x}^{ab}$ .

$x=2^{\frac{2}{3}}$

Decimal Form: 1.587401

__________________________________________

Check the answer:

$2x^3-8=0$

1) Let $x=2^\frac{2}{3}$ .

$2(2^{\frac{2}{3} })-8=0$

2) Use this rule: $(x^a)^b=x^{ab}$ .

$2\times2^{\frac{2\times3}{3} } -8=0$

3) Simplify 2 * 3 to 6.

$2\times2^{\frac{6}{3} } - 8 =0$

4) Simplify 6/3 to 2.

$2\times2^2-8=0$

5) Use Product Rule: $x^ax^b=x^{a+b}$ .

$2^3-8=0$

6) Simplify 2^3 to 8.

8 - 8 = 0

7) Simplify 8 - 8 to 0.

0 = 0

Thank you,

Eddie
