Answer:
D
Step-by-step explanation:
4x²= 32
x²= 32 ÷4 <em>(</em><em>÷</em><em>4</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
x²= 8
x= ±√8 <em>(</em><em>square</em><em> </em><em>root</em><em> </em><em>bith</em><em> </em><em>sides</em><em>)</em>
☆ A '±' symbol has to be added whenever we introduce a square root as the square of any number, positive or negative, would result in a positive number.
Answer:
<u>scalene</u>
Step-by-step explanation:
Length of XZ = √3² + 4² = √25 = 5
Length of ZY = √1² + 7² = √50 = 5√2
Length of XY = √4² + 5² = √41
As all lengths are different, the triangle is <u>scalene</u>
If the graph of x is shifted 7 units up, the equation of the new graph would be: f(x) = x +7.
<h3>Transformations in graphs</h3>
According to the question:
- The given equation is: f(x) = x
On this note, when the graph of the equation is shifted 7 units up, it follows that every f(x) value of the graph increases by 7 units.
Hence, the equation of the new graph is; f(x) = x +7.
