One hundred students go to the cafeteria to
eat lunch. Six tables held the same amount of
students while an additional 10 students
stood in line. Which equation can be used to
find the number of students sitting at each
table?
A 100= 10x + 6
B 100 + 6 x= 10
C 10 x - 100 = 10
D 6x + 10 = 100
Answer:
D
Step-by-step explanation:
6x + 10 = 100
6 times 15 = 90
Add 90 + 10 = 100
Answer:
the answer is d

1 What is the nature of the roots of the quadratic equation if the value of its discrimman
is zero?
The roots are not real
o the roots are rational and not equal
b. The roots are irrational and not equal d the roots are rational and equal
2. Whal is the ans of symmetry of the parabola y
Answer:
If d is zero, both roots are rational and equal.
Step-by-step explanation:
Quadratic Equations
The standard representation of a quadratic function is:
[tex]f(x)=ax^2+bx+c[/tex]
where a,b, and c are constants.
Solving with the quadratic formula:
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
The discriminant is defined as:
[tex]d=b^2-4ac[/tex]
The sign of the discriminant defines the nature of the roots of the quadratic equation as follows:
If d is positive, both roots are real and differentIf d is negative, both roots are imaginary and conjugateIf d is zero, both roots are rational and equal.17.546 rounded to the nearest hundred

Find the slope of the line through the points (-7, - 12) and (1, -16)
Answer:
y =
-1x/2 – 31/2
Step-by-step explanation:
The vertices of a rectangle are R(-5, -5), S(-1,-5), 7(-1, 1), and U(-5, 1). After translation,
R' is the point (-11, -11). Find the translation rule and coordinates of U'.
(x, y) + (x - 6, y + 6); (-11, 7)
(x, y) (x - 6, y - 6); (-11,-5)
(x,y) → (x + 6, y - 6); (1, -5)
(x, y) + (x + 6, y + 6); (1,7)
Answer:
B. (x, y) (x - 6, y - 6); (-11,-5)
Step-by-step explanation:
Given the vertices of a rectangle are R(-5, -5), S(-1,-5), 7(-1, 1), and U(-5, 1). After translation, the coordinate R' is at the point (-11, -11), in order to know the translation factors used;
Let (x, y) be the translation coordinate added to the original coordinate R to get R'. To get the coordinate (x, y)
(x, y)+(-5, -5) =(-11, -11)
x - 5 = -11
x = -11+5
x = -6
Similarly;
y-5 = -11
y = -11+5
y = -6
Hence the coordinates added to initial vertices is (-6, -6)
To get the new coordinate U' after translation, we will add the coordinate (-6, -6) to the U(-5, 1) as shown;
(x, y) + (-5, 1) = (-6, -6)+(-5, 1)
= (-6-5, -6+1)
= (-11, -5)
Hence the coordinates of U' is (-11, -5) and the translation rule is (- 6+ x, -6+y) where (x, y) is (-6, -6).
Based on the above calculation, it can be seen that (x, y) (x - 6, y - 6); (-11,-5) is correct.

The editor of a textbook publishing company is deciding whether to publish a proposed textbook. Information on previous textbooks published show that 20 %20% are huge successes, 30 %30% are modest successes, 30 %30% break even, and 20 %20% are losers. Before a decision is made, the book will be reviewed. In the past, 99 %99% of the huge successes received favorable reviews, 60 %60% of the moderate successes received favorable reviews, 40 %40% of the break-even books received favorable reviews, and 30 %30% of the losers received favorable reviews. If the textbook receives a favorable review, what is the probability that it will be huge success?
Answer:
[tex]Probability = 0.198[/tex]
Step-by-step explanation:
Given
Publish
[tex]Huge\ Success = 20\%[/tex]
[tex]Modest\ Success = 30\%[/tex]
[tex]Break\ Even = 30\%[/tex]
[tex]Losers = 20\%[/tex]
Favorable Reviews:
[tex]Huge\ Success = 99\%[/tex]
[tex]Modest\ Success = 60\%[/tex]
[tex]Break\ Even = 40\%[/tex]
[tex]Losers = 30\%[/tex]
Required
Determine the probability that a textbook is huge success and favorable
To do this, we simply multiply the probability of a textbook being huge success and being favorably reviewed. as follows;
[tex]Probability = 20\% * 99\%[/tex]
[tex]Probability = 0.198[/tex]

What is the equation for this line?
Answer:
The equation of the line is y = 2x - 3
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope of the line, [tex]m=\frac{y2-y1}{x2-x1}[/tex] b is the y-intercept (value y at x = 0)Let us take two points on the line to find its equation
∵ Points (3, 3) and (0, -3) lie on the line
∴ x1 = 3 and y1 = 3
∴ x2 = 0 and y2 = -3
→ Use the rule of the slope above to find m
∵ [tex]m=\frac{-3-3}{0-3}=\frac{-6}{-3}=2[/tex]
∴ m = 2
→ Substitute its value in the form of the equation above
∴ y = 2x + b
∵ b is the value of y at x = 0
∵ y = -3 at x = 0
∴ b = -3
→ Substitute it in the equation above
∴ y = 2x + -3
→ Remember (+)(-) = (-)
∴ y = 2x - 3
∴ The equation of the line is y = 2x - 3
