PLEASE PLEASE HELP ME WITH THIS, SO CONFUSED (image attached) explain it please !!!
1 answer:
Because the figures are similar, they have same proportion for the sides.
Compare the sides
hypotenuse/base = hypotenuse/base
(x - 9) / 4 = (x + 1) / 9
Do cross multiplication, then simplify
9(x - 9) = 4(x + 1)
9x - 81 = 4x + 4
9x - 4x = 4 + 81
5x = 85
x = 85/5
x = 17

Answer:
Graph the equation is shown below.
Step-by-step explanation:
The linear equation representing the relation between cost of ordering a pizza and the number of additional toppings is:
Here,
<em>y </em>= cost of the pizza
<em>x</em> = number of toppings
The graph of the linear equation is shown below.
Consider the point (2, 10.25).
When <em>x</em> = 2 compute the value of <em>y</em> as follows:
The point (2, 10.25) satisfies the equation.
Again consider a point (18, 18.25).
When <em>x</em> = 18 compute the value of <em>y</em> as follows:
The point (18, 18.25) satisfies the equation.
The two points are also plotted on the graph.
The answer would be 15.7142857143
