Mathematics
1 answer:
cupoosta [38]2 years ago
6 0

Answer:

x = -5

x = -12

Step-by-step explanation:

- 7x - 60 = x^2 + 10x

add 7x to both sides

x^2 + 17x = -60

add 60 to both sides

x^2 + 17x + 60 = 0

factorise quadratic

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

<em>x = -12</em>

<em>x = -12x = -5</em>

4x - 5 - 2x = x - 5<br><br> No Solution<br> X=0<br> X=4<br> X=5
Alekssandra [29.7K]

Answer:

x = 0

Step-by-step explanation:

Step 1: Write equation

4x - 5 - 2x = x - 5

Step 2: Solve for <em>x</em>

  1. Combine like terms: 2x - 5 = x - 5
  2. Subtract x on both sides: x - 5 = -5
  3. Add 5 to both sides: x = 0

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

4(0) - 5 - 2(0) = 0 - 5

0 - 5 - 0 = -5

-5 = -5

How does the graph of the function g(x)=2^x-4 differ from the graph of f(x)=2^x
VARVARA [1.3K]

Answer:

The graph of g(x) is the graph of f(x) moved down 4 units.

Step-by-step explanation:

Subtracting a function by a constant:

Subtracting a function by a constant x is the same as moving the function down x units.

In this question:

f(x) = 2^x

g(x) = 2^x - 4

Thus, the graph of g(x) is the graph of f(x) moved down 4 units.
