Answer:

2 greater than or equal to-9

Step-by-step explanation:

since the graph has an equation of x²+2x-8

to find the value of x when y=0 find two numbers that if you multiply them together it will give you -8 and if you add them they will give you +2

+4x-2=-8

+4+(-2)=+2

so x²+2x-8=0

can be writteb as (x+4)(x-2)=0

so one time x+4=0 so x=-4

and one time x-2=0 so x=2

so x roots at -4 and 2

to find y when x=0

0²+2(0)-8=-8

so y root at -8

(shown in graph above)

the range is from minimum point to the maximum(down to up) for the y values

there is no maximum point so the graph goes to infinity

the minimum is the middle point between the two x roots so take an average of them

(-4+2)÷2=-1

so when x=-1

(-1)²+2(-1)-8=-9

so the minimum starts from -9 going up to infinity

so the answer is greater or equal to-9

What is 10 1/3 x 1/4? that is, what is ten and one third times one fourth?
Phantasy [73]

Answer: 31/12, or 2 7/12

Step-by-step explanation: The answer is actually very simple. All you have to do is to simplify 10 1/3 into 31/3, as 10x3+1=31. Then, you have to multiply 31/3 with 1/4. Do a simple fraction multiplication, and you get 31/12, or 2 7/12 if your teacher is asking for a mixed number. Sometimes simplifying is better

The answer is: x is choose your answer
katrin2010 [14]

Answer:

All real numbers

Let's find the critical points of the inequality.

−4x+7=17

−4x+7+−7=17+−7(Add -7 to both sides)

−4x=10

−4x−1=10−1

(Divide both sides by -1)

4x=−10

4x=−10(Solve Exponent)

log(4x)=log(−10)(Take log of both sides)

x*(log(4))=log(−10)

x=log(−10)log(4)

x=NaN
