MArishka [77]3 years ago

Answer:

x = 27

Step-by-step explanation:

Vertical angles are congruent.

5(x - 4 ) = 4x +7

5x - 20 = 4x + 7   {Distributive property}

Add 20 to both sides

5x = 4x + 7 + 20

5x = 4x  + 27

Subtract 4x from both sides

5x - 4x = 27

x = 27

Answer:

x = 27

Step-by-step explanation:

vertical angles are congruent , then

5(x - 4) = 4x + 7 ← distribute parenthesis on left side

5x - 20 = 4x + 7 ( subtract 4x from both sides )

x - 20 = 7 ( add 20 to both sides )

x = 27

What is the volume, in cubic in, of a rectangular prism with a height of zin, a width of
Delicious77 [7]

2 The question isn't well formatted, thus the length and width aren't given. Hence, we take a value in place of both to. Obtain an hypothetical solution.

Answer:

60 in³

Step-by-step explanation:

To obtain the volume eof a rectangular prism, we use the formular :

Volume of rectangular prism = Length * width * height

Let width = 5 inches ; height = 6 inches; lebgth = 2 inches

Volume of rectangular prism = (6 in * 5 in * 2 in) = 60 in³

Kindly note that the width and height values are hypothetical values as the values in the question aren't well formatted.

1) y=-5^{-x}, y = x+5 ,
\\ \\ -5^{-x}=x+5
\\ \\  ln(-5^{-x})=ln(x+5)
\\ \\ ln(- \frac{1}{5^{x}} )=ln(x+5),

you cannot find ln of negative number, so it is going to be

 "0" solutions.


The graphs of these equations will not intersect. 

2) y = 4(1.2)^{x}, y = x+7
\\ \\ x+7= 4(1.2)^{x}

graphs have 2 intersects, so two solutions.

3) y= {0.5}^{x} , y =6, \ 6=0.5^{x}

One intercept. so one solution
