Answer:
Third bar graph.
Step-by-step explanation:
Given : 5x + 7.5 = 15.
To find : Which bar diagram represents the equation.
Solution : We have given 5x + 7.5 = 15
In the equation we can see sum of 5x and 7.5 is 15 .
By the bar graph combination box of 5x and box of 7.5 is equal to the box of 15.
Then Third bar graph represent the equation .
Two pink boxes of 5x and 7.5 and one blue box of 15.
Therefore, Third bar graph.

Answer:
7x + 3y = 44
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c (m is the slope and c the y- intercept )
Rearrange - 3x + 7y = 5 into this form by adding 3x to both sides
7y = 3x + 5 ( divide all terms by 7 )
y = x + ← in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = - , thus
y = - x + c ← is the partial equation
To find c substitute (5, 3) into the partial equation
3 = - + c ⇒ c = 3 + =
y = - x + ← in slope- intercept form
Multiply through by 3
3y = - 7x + 44 ( add 7x to both sides )
7x + 3y = 44 ← in standard form
