Answer:
x = 81/4
Step-by-step explanation:
multiply both sides by 4
4x + 15 = 96
subtract 15 from both sides
4x = 81
divide both sides by 4
x= 81/4
i hope that's right
Do you have an example?
it probably means to tell you to make I the main subject of the whole equation.
e.g. I = 2y + x^2 - x^3
<em> I </em>hope you find this useful, Mark as Brainliest please, it's very much appreciated.
Explanation:
In one minute, Diego can type 35 words;140÷4
At this rate, it will take him 11 minutes to type 385 words;385÷35
Therefore, he can type 525 words in 15 minutes; 35×15
Answer:
The length of side XZ should be greater than 10 and lesser than 60.
Step-by-step explanation:
In triangle XYZ ,
As
The length of side XY = 25 mm
The length of side YZ = 35 mm
Range of the third side can be computed when we already know the two sides of the triangle.
If subtracting , the 3rd side would have to be more than 10. Else 3rd side can not be made as two smaller legs will not meet.
and
If adding , the 3rd side would have to be less than 60. Else 3rd side will reach further than the the other two sides could reach.
Therefore, the length of side XZ should be greater than 10 and lesser than 60.
The choices are points of a function that lies at coordinates (x,y). Just do trial and error with each choice and see which applies
a) x = 0, y = 0
-5(0)^2 + 20(0) - 17 > 0
-17 > 0 (not true)
b) x = 2, y= 2
-5(2)^2 + 20(2) - 17 > 2
3 > 2 (true)
c) x =5, y=2
-5(5)^2 + 20(5) - 17 > 2
-42 > 2 (not true)
d.) x=1, y=5
-5(1)^2 + 20(1) -17 > 5
-2 > 5 (not true)
So, the answer is B.
