Answer:
21
Step-by-step explanation:
multiple both sides by 7
v = 21
Check:
21/7 = 3
3 = 3
Answer:
If a shape is a square, then it is a quadrilateral
Step-by-step explanation:
Quadrilateral means four sided shape, so automatically, because a square has 4 sides, you know it is a quadrilateral. But not all quadrilaterals are a square, you could have a rectangle which is four sides so you know that this statement is wrong "If a shape is a quadrilateral, then it is a square." Therefore, the answer is "If a shape is a square, then it is a quadrilateral
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:
no solution
Step-by-step explanation:
|f-6| = |f+8|
solve absolute values
f-6 = f+8
add 6 to 8
f = f+14
subtract f from f
0=14
not true; no solution
