Answer:
No, for 2(4)+1+3 does not equal 0 it equals 12
Step-by-step explanation:
first we have
2x+1+3=0 x=4
replace x with 4
2(4)+1+3=0
then following pemdas
8+1+3=0
finish it up
12=0
Answer:
-28
Step-by-step explanation:
Plug in -2 where m is and 5 where n is in the equation
1. 9(-2) -2(5)
2. = -18 -10
3. The answer is -28
Answer:
hello buddy i can't draw here but this is a type angle
acute angle
Use the fact that 72 degrees are an acute angle so it will be less than 90 degrees.
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.
