Answer:
The equation for relationship between the thickness and the number of weeks is f(x)=3.8 -0.2*x
Step-by-step explanation:
Ice thickness decreases at a rate of 0.2 meters per week. This can then be represented by the expression
f(x) = k - 0.2*x
where k is the thickness of the ice before the melting starts and x is the number of weeks.
After 7 weeks, the ice is only 2.4 meters thick. This means that x has a value of 7, while f (7) = 2.4. Replacing in the previous expression:
2.4=k -0.2*7
and solving you get:
2.4=k- 1.4
2.4 + 1.4= k
3.8= k
Then, <u><em>the equation for relationship between the thickness and the number of weeks is f(x)=3.8 -0.2*x</em></u>
The X coordinate changes when you translate a figure left.
1<em>.) </em><em>Reduction</em>
<em>As you can see Triangle A was reduced in size as a result of Triangle B</em>
<em>2.) </em><em>Enlargement</em>
<em>Square A is much smaller than square B, making this an enlargement</em>
<em>3.) </em><em>Enlargement</em>
<em>The quadrilateral shown here gets larger with quadrilateral B</em>
<em>4.) </em><em>Reduction</em>
<em>This object gets vividly smaller as shown on the graph, making it a reduction </em>
Answer:
x = <u>+</u>3
Step-by-step explanation:
4x² = 36
sqareroot both side we get,
√4x² = √36
2x = 6
x = 6/2
x = <u>+</u>3
Thus, The answer is <u>+</u>3
