What could be the first step toward correctly solving the equation 5x+70=−3x−10

Mathematics

klasskru [66]4 years ago
7 0

Answer:

Add '-3x' to each side of the equation.

-70 + 5x + -3x = -10 + 3x + -3x

Combine like terms: 5x + -3x = 2x

-70 + 2x = -10 + 3x + -3x

Combine like terms: 3x + -3x = 0

-70 + 2x = -10 + 0

-70 + 2x = -10

Add '70' to each side of the equation.

-70 + 70 + 2x = -10 + 70

Combine like terms: -70 + 70 = 0

0 + 2x = -10 + 70

2x = -10 + 70

Combine like terms: -10 + 70 = 60

2x = 60

Divide each side by '2'.

x = 30

Simplifying

x = 30

stellarik [79]

Answer:

C. f(x)=3(1/2)^x

Step-by-step explanation:

standard form of a function is f(x)=ab^x

a should be 3, or the y value where the x value is 0

the b value is 1/2 because that's the rate of change

Convert 0.827 to a fraction or in simplest form
dangina [55]
<span>0.827 = 0.827 / 1


Numerator = 0.827 × 10 × 10 × 10 = 827
Denominator  = 1 × 10 × 10 × 10 = 1000

Numerator / Denominator = 827 / 1000

Simplifying our fraction

= 827/1000

= 827/1000</span>
