Answer:
10
Step-by-step explanation:
because 7÷35 =5 but that would be for only one pencil so if u multiply that 5×2 it would be 10 pencils
The answer to this is x > -2
Answer:
x1 = 4
x2 = -5
Step-by-step explanation:
There is a formula to solve the quadratic equations, which is:
[-b +- √ (b² - 4 ac) ] / (2a)
Quadractic equations have this look:
ax² + bx + c = 0
You need to stablish the numbers:
where a, is the number with x², b the x and c, the independent term.
x² + x - 20 = 0 For this case:
a = 1 ; b = 1 ; c = -20. We replace in the formula
[-1 +- √ (1² - 4 1 (-20)) ] / (2 .1)
(-1 + √81) / 2 = 4
(-1 - √81) / 2 = -5
Answer:
Option C =
Step-by-step explanation:
As you can see from the graph, one of the points lying on the graph is (3,1).
Inserting this point in above all equations, we get,
1] <em> = -1</em> , which is not equal to 1.
2]<em> </em>= 4.464 , which is not equal to 1.
3]<em> = 1</em> , which is equal to 1.
4] <em> = 2.464</em> , which is not equal to 1.
Thus, only option 3 satisfies the point.
One can also check for other points.
