Let E = total earnings per month and x represents the number of items sold.

Since the expression 5x + 350 is the earnings per month, this means E = 5x + 350.

We want the earnings (E) to be "at least 950", which means we want E to be equal to 950 or larger. So we can say

E >= 950

The symbol ">=" without quotes means "greater than or equal to"

Replace the "E" with "5x+350" and solve for x

E >= 950
5x+350 >= 950
5x+350-350 >= 950-350
5x >= 600
5x/5 >= 600/5
x >= 120

So you are close, but the answer is choice C. This means she must sell 120 items or more.

The function h is defined by h(x)=b−9÷x, where b is a constant. Find b, if the graph of h passes through the point (−6,19).

Paraphin [41]

H (x) = b - 9/x
At (-6 , 19) ,
h (x) = 19 , x = -6 ,
19 = b - (9/-6)
19 = b + 3/2
b = 35/2

In the given figure PQ is a transversal intersecting lines AB and CD. Find the measures of angles x and y. Hence prove AB//CD.

tekilochka [14]

Explanation:

From the given figure ,

AB || CD

PQ is a transversal

Given angles are 50° and 130°

50° and x are linear pair

⇛ 50°+x = 180°

⇛ x = 180°-50°

⇛ x = 130°

Therefore, "x" = 130°

and

130° and y are vertically opposite angles which are equal.

⇛ "y" = 130°

Therefore, y = 130°

Additional comment:-

If two parallel lines Intersected by a transversal then
Corresponding angles are equal.
Vertically Opposite angles are equal.
The sum of two adjacent angles is equal to 180° then they are called Linear Pair.
