5x + 2y = 7
zvonat [6]

Answer:

(\frac{5}{7},\frac{12}{7})

Step-by-step explanation:

The given system is

5x+2y=7

y=x+1

We substitute the bottom equation into the top equation to get:

5x+2(x+1)=7

Expand to get:

5x+2x+2=7

Group similar terms:

5x+2x=7-2

Combine similar terms:

7x=5

x=\frac{5}{7}

Put x=\frac{5}{7} into the bottom equation

y=\frac{5}{7}+1

y=\frac{5+7}{7}

y=\frac{12}{7}

The solution is

(\frac{5}{7},\frac{12}{7})

Not drawn to scale

StartFraction 1 over x EndFraction = StartFraction 2 over 6 EndFraction

StartFraction 1 over x EndFraction = StartFraction 6 over 2 EndFraction

StartFraction 1 over 6 EndFraction = StartFraction 2 over x EndFraction

ANSWER THIS QUESTION IF YOUR GOOD AT MATH ↓
blondinia [14]

Answer:

It's C, g(x) = (1/2)^x

This is a horizontal reflection of y = 2^x

across the y axis.

Step-by-step explanation:

Using the process of elimination, you can spot this answer by applying what is logical about the transformations of an exponential function.

The transformations of a standard exponential function can be given by:

ab^(1/c(x-h))+k

First note that A must be incorrect because -2^x would be a reflection across the x axis which would not match the function g because a reflection across the x axis would cause the exponential growth or decay value b to become a reciprocal and -2 is not a reciprocal of 2.
