4x -2(12x-1)= 14
4x-24x+2=14
-20x+2=14
-20x=12
x=-0.6 or -3/5
i don't know if there is a graph for this problem, but m1 should always equal m2
if m1 and m2 are parallel, one line that is perpendicular to m1 is always perpendicular to m2, and the slopes of m1 and m2 are equal and their lines should never intersect
Answer:
b) x-intercept
Step-by-step explanation:
First Vilgot made a hat with some amount of yarn, let us assume the weight of yarn used to be 'h', which is fixed. Then we assume the weight of yarn used to make unit length of scarf be 'm'.
The sum of the weight of yarn used to make hat and scarf both is 'x' and the length of scarf is 'y', as given in the question.
The sum of weight of scarf and hat can also be expressed as:
<em>( weight of yarn used to make hat ) + ( weight of yarn used to make unit length of yarn ) × ( length of scarf made )</em>
The above equation in terms of variables (assumed and given) will appear like:
here m and h are constants.
The above equation is represented by the graph given in the question.
So, if in the equation we substitute <em>y=0</em> then <em>x=h</em> which is x-intercept.
Therefore the <u>x- intercept</u> of graph give h which is the weight of yarn used to make hat.
Answer:
He needs to work for 40 whole hours
Step-by-step explanation:
In this question, we are tasked with calculating the amount a Tv will cost Bob in terms of the number of hours he needs to work.
Let’s look at the total cost he has to pay.
a. $500
b. 8% tax = 8/100 * 500 = $40
c. He is paying 2 bills of $35 each making a total of 2 * $35 = $70
The total amount he is to pay is thus; 500 + 40 + 70 = $610
Let’s look at his income ;
a. Bonus $45
b. Birthday gift $85
The total amount of money he has asides his salary to offset the bill is 45 + 85 = $130
The balance to pay from his salary would be $610 - $130 = $480
The number of hours he has to work since he earns $12 per hour would be 480/12 = 40 hours of work
This is not solvable there is no given total in my opinion
