3x-2y=8 and 0.5x+y=17

levacccp [35]

2y is in the first equation so if you change 0.5x+y=17 to y=17-0.5x and then double it to 2y=34-x, you can substitute and find x. And then you can find out y.

How to find x:

0.5x+y=17

y=17-0.5x

2y=34-x

3x-2y=8

3x-34-x=8

x=21

How to find y (with previous info.)

x=21

3x-2y=8

3*21-2y=8

63-8=2y

55=2y

27.5=y

Help please im pretty sure this is called angle sum theory but I could be wrong

DENIUS [597]

y = 25

Step-by-step explanation:

=> 115 = y + 90 {exterior angle of triangle is equal to the sum of its opposite two interior angles}

=> 115 = y + 90 

=> 115-90 =y

=> 115 = y + 90

=> 115-90 =y

=> y = 25

Consider the attached function - The values are?

kow [346]

To find the value f(-7), we just need to evaluate the function at $x=-7$ . In other words, we are going to replace $x$ with -7 in the function:
$f(x)=( \frac{1}{2} )^x$
$f(-7)=( \frac{1}{2})^{-7}$
$f(-7)=128$

Similarly, to find the value of f(5), we just need to evaluate the function at $x=5$ . In other words, we are going to replace $x$ with 5 in the function:
$f(x)=( \frac{1}{2} )^x$
$f(5)=( \frac{1}{2})^{5}$
$f(5)=0.031$

We can conclude that $f(-7)=128$ and $f(5)=0.031$
