Write an equation for the description.
Ten times the sum of half a number x and 7 is 9.

10( 1/2x + 7) = 9

Step-by-step explanation:

This is the answer because:

1) 10 times the sum is representing 10 multiplied by the sum of two numbers

2) The sum of half a number x and 7 is 1/2x + 7 because you have to figure out 1/2 of x first and then add it with 7

3) This whole entire expression is supposed to equal to 9, so the final answer is 10( 1/2x + 7) = 9

4) 1/2x + 7 is in parenthesis because you have to figure out the sum of those two number and then multiply it with 10

Hope this helps!

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
