Answer:
-7
Step-by-step explanation:
You use the quadratic formula of [tex]ax^{2} +bx+c = 0[/tex] to get:
a = 1
b = 7
c = -13
then you plug that into x= (-b ± √b²-4ac)/(2a) :
x= ( -7 ± √7²- 4(1)(-13) )/(2(1))
[tex]x=-\frac{7}{2} + \frac{\sqrt{101}}{2} \\\\x=-\frac{7}{2} - \frac{\sqrt{101}}{2}[/tex]
The sum of these two x values turns out to be:
[tex]x=-\frac{7}{2} + \frac{\sqrt{101}}{2}+( -\frac{7}{2} - \frac{\sqrt{101}}{2} )= -\frac{14}{2} = 7[/tex]
Jack needs 22 pirates for every 2 pirate ships he manages.
Answer:
55, 121
Step-by-step explanation:
2*2 =4
22*2=44
but 4 is not the number we need and 4 is one less so we divide 22 by 2 and get 11 so 44+11=55
thats the first box.
The second box is 55*2+11 which is 121
55:is the first box
121 is the second empty box
Which graph represents y as a function of x ?
Answer:
The second one
Step-by-step explanation:
Simply put, in order to be a function the x can not repeat and that is the only graph where they x does not repeat.
Second one graph is represents y as a function of x.
Here four graph shown.
We have to check which graph shows y as a function of x.
What is function?
If for each value of x, there is only one possible value of y or As a graph, if we trace a vertical line; it cannot cross more than one point of the function; then it is called function.
To solve this question we use the definition of function,
In first graph, when we draw vertical line then it intercepts on graph in more than one point, so it does not represents y as a function of x
Similarly, in third and fourth graph we use vertical line test.
Hence, only in second one graph, the vertical line test will be fulfill.
So, Second one graph is represents y as a function of x.

Write an expression that is equivalent to three over four (5z+ 16).
15 over four z + 16
15 over four z + 12
three over four z + 16
three over four z + 12
Your answer is 15 over four z + 12. Using the distributive property, 3/4 • 5z equals 15/4z, which can't be simplified. Then 3/4 of 16 is 12. If you divide 16 by 4 (the denominator) and then multiply by 3 (the numerator) that yields your answer.

PQ is parallel to RS
Use the diagram to findeasure of angle 2
Answer: 140
Step-by-step explanation: Since the lines are parallel, they have the same measured angles. Angle RS and angle PQ are both straight lines, meaning they are supplementary angles (180), and angle RA is 40 degrees, so you subtract 180(the total) by 40 to get the answer 140.

an inequality is ?
the solution is ?
Answer: The inequality is x/3 [tex]\leq[/tex] 4 and x [tex]\leq[/tex] 12
Step-by-step explanation:
The quotient of x and 3 is the same as x/3 and the at most sign is less than or equal to. x/3 has to be less than or equal to 4 which can be represented by the inequality,
x /3 ≤ 4 Solve for x by multiplying both sides by 3.
x ≤ 12

Michael is doing an underwater handstand. His feet are sticking up 0.5 meters above the surface of the water. Michael's hands are 1.8 meters directly below his feet.
What is the position of Michael's hands relative to the surface of the water?
Group of answer choices
A. 1.8 meters
B. 1.3 meters
C. 0.5 meters
D. -0.5 meters
E. -1.3 meters
F. -1.8 meters
Answer: 1.3 Meters or B
Step-by-step explanation:
To answer this question, it must be noted first that the reference points of the given distances in this item is (1) the surface of the water and (2) the feet. We are given with the distance from the hand to the feet, 1.8 m, and from the feet to the surface of the water, 0.5 m. To get the distance from the hands to the surface of the water, we just have to subtract the given distances giving us an answer of 1.3 m.
Answer:
e. -1.3 meters
Step-by-step explanation:
subtract 1.8 by 0.5 and you get 1.3 since youre below water level youd put - in front of 1.3 since its negative
