Answer: x=3

Step-by-step explanation:

3x + 5 = 14

Subtract 5 from both sides

Divide both sides by 3 to get x alone

x=3

What is the slope of the line through (-7, -2) and (-6, 7)?
Reil [10]

Answer:

\displaystyle =9

Step-by-step explanation:

The slope formula is

\displaystyle \frac{y_2-y_1}{x_2-x_1}

\displaystyle y_2=7\\\displaystyle y_1=(-2)\\\displaystyle x_2=(-6)\\\displaystyle x_1=(-7)

\frac{7-(-2)}{(-6)-(-7)}=\frac{9}{1}=9

Therefore, the slope is 9, and the correct answer is 9.

Hope this helps!

Can anybody help me with this
kondaur [170]

Answer:

c ≈ 9.1 m

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

c² = 4.1² + 8.1² = 16.81 + 65.61 = 82.42 ( take square root of both sides )

c = \sqrt{82.42 } ≈ 9.1 m ( to the nearest tenth )

20 points and crown determine the product of each set of polynomials (2x-3)(4x+5)=0
bonufazy [111]
Remember to make the polynomials to equal zero, one or the other polynomial must equal zero. So...

2x-3 = 0

2x= 3

x=3/2

and

4x+5 = 0

4x = -5

x = -5/4

So the answers are x=3/2 and x = -5/4

Hope this helps!

Pleaseeeeee solveee 25 points pleaze help geometry

Answer:

(-3/2, 6)

Step-by-step explanation:

(-3,8) (6,-4)

As we move along the line segment with endpoints (-3,8) and (6,-4) from  (-3,8) to (6,-4) x increases by 9 units (from -3 to 6) and y decreases by -12 units (from 8 to -4).

for ratio of 1:5

Since 1+5=6, the point we are looking for is 1/6 of the way from (-3,8) to (6,-4).  

So, the desired point is

(-3 + (1/6)(9), 8 - (1/6)(12) )

= (-3 + 3/2 , 8 - 2)

= ( (-6 + 3)/2, 6)

= (-3/2, 6)
