Answer:
y= $50x + $25
Step-by-step explanation:
Slope-intercept form is y=mx+b
x is something that is constant
b is something you add on to the constant
Answer:
The constant of proportionality is option D i.e 5.
Step-by-step explanation:
Variation:
Variation problems involve fairly simple relationships or formulas, involving one variable being equal to one term. There are two types of variation i.e.
- Direct variation
- Inverse variation
Direct Variation:
Mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other.
Example 
where, k is constant of proportionality.
The above given example is of Direct Variation
∴ y = 5 x
∴ k = 5 = constant of proportionality.
Inverse Variation:
Mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.
Example 
where, k is constant of proportionality.
3.5 + 2 = 2x - 10
5.5 = 2x -10
+10 +10

7.75 = x
7.75 is the answer
Answer:
c = -4
Step-by-step explanation:
16 = 4 - 3c
subtract 4 from each side
16-4 = 4-4 - 3c
12 = -3c
Divide each side by -3
12/-3 = -3c/-3
-4 =c
Answer:
The final interior angle = 124°
Step-by-step explanation:
A heptagon has 7 sides. The sum of the interior angles formula:
The sum of the interior angles = (n - 2)180 where n = number of sides.
The sum of the interior angles= (7 - 2)180° = 900°
Six interior angles = 776°.
The final interior angle + six interior angle = 900°
The final interior angle + 776° = 900°
The final interior angle = 900° - 776°
The final interior angle = 124°
