That is what I got ¡my teacher showed me that method in school .
Answer:
x = -5
Step-by-step explanation:
3x=-15
Divide each side by 3
3x/3 = -15/3
x = -5

Answer:
see attached.
Step-by-step explanation:
Your graph demonstrates a possible function, but it has the domain and range swapped.
__
The <em>domain</em> is the <em>horizontal</em> extent, so your line must end at x=-9 on the left and x=6 on the right.
The <em>range</em> is the <em>vertical</em> extent, so the function must extend from -4 at the bottom to +8 at the top.
The attachment shows a linear function with those characteristics.
Answer:
x = 5
Step-by-step explanation:
The axis of symmetry is the vertex x coordinate
Answer: 0.4286
Step-by-step explanation:
Given : Total components = 7
Number of bad component in 7 electrical components = 1
Number of good component in 7 electrical components = 7-1=6
The number of combinations of selecting any 4 components =
The number of combinations of selecting all 4 good components =
Then, the probability that all selected components function properly will be :
Hence, the probability that all selected components function properly. is 0.4286 .
