How many roots does y=3x^2+8 have?
Answers
Answer:
This quadratic has two unequal, imaginary roots.
Step-by-step explanation:
y = 3x^2 + 8 is a quadratic function, and (like all quadratics) it has two roots. In this case they happen to be different (unequal), as well as imaginary.
Setting y = 3x^2 + 8 = 0, we get:
3x^2 = -8, or
x^2 = -8/3
Taking the square root of both sides, we get
x = ±i√(8/3) (2 imaginary roots)

Answers

Answer:
C 3x +1 = y
Step-by-step explanation:
x-values increase by 1 from row to row.
y-values increase by 3 from row to row.
The slope of the linear function is the ratio of the y-increase to the x-increase:
m = ∆y/∆x = 3/1 = 3
The only offered choice with an x-coefficient of 3 is ...
C 3x +1 = y

If you check this against the table entries, you find it fits.
3(1) +1 = 4
3(2) +1 = 7
and so on.

16
D
multiply both sides of the equation by
7
Answers
Answer:
A. Add -2 to both sides
Step-by-step explanation:
The reason you need to add -2 to both sides is because if you add -2 to -2 it cancels out and you are left with x=18. But you need to add -2 to 18 too because them the equation won't be equal anymore.

Suppose the ratio of girls to boys in your school is 19:17. There are 1908 students altogether. Write and solve a system of equations to find the total number of boys and girls in the school.
Answers
Answer:
901 boys and 1007 girls
Step-by-step explanation:
let b be the number of boys
let g be the number of girls
[tex]b + g = 1908\\17g = 19b\\g = \frac{19}{17} b\\b+\frac{19}{17} b = 1908\\2\frac{2}{17}b = 1908\\b = 901\\901 + g = 1908\\g = 1007[/tex]
A student claims that the expression “9 times the sum of a number and 13" is translated to the algebraic expression 9n + 13. Is the student correct? If not, what is the correct expression?
Answers
Answer:
No, the student is not correct. The correct expression is 9(n+13).
Step-by-step explanation:
"9 times the sum of a number and 13" means you must multiply 9 by the sum, not just by the number. 9n + 13 would be "the sum of 9 times a number and 13." Slightly different wording.
Answer:
Sample Response: The student is not correct. He should use parentheses like this 9(n+13). Without the parentheses, it means nine times n plus 13, but should be the sum of n plus 13 multiplied by 9.
N 1846 the depth of the river was 5 feet deep. In 1847 it dropped to 3.2 feet. This year, 1848, it rose to 6.6 feet. Find the percent change in river depth
Answers
Answer:
40.4%
Step-by-step explanation:
Given data
Initial depth= 5feet
Final depth= 5-3.2+6.6= 8.4feet
Hence the percent change
% change= FInal-initial/final*100
% change= 8.4-5/8.4*100
% change= 3.4/8.4*100
% change= 0.404*100
% change=40.4%
Hence the percent change is 40.4%
Percentage change between two measurement is the proportion of
change between the measurement expressed as a percentage.
The percentage change in the river depth in in 1848 is 106.25%
Reasons:
The given parameters are;
The depth of the river in the year 1846 = 5 feet
In the year 1847, the depth = 3.2 feet
In 1848 the depth = 6.6 feet
[tex]\displaystyle Percentage \ change = \mathbf{ \frac{Current \ depth - Previous \ depth}{Previous \ depth}}[/tex]
Which gives;
[tex]\displaystyle Percentage \ change = \frac{6.6 -3.2}{3.2} \times 100 = \mathbf{106.25 \%}[/tex]
The percentage change in the river depth in the current period = 106.25%

Answer:
ecall that 6 + 6 + 6 = 6 × 3
Instead of adding 6 three times, you can multiply 6 by 3 and get 18, the same answer.
Similarly,
6 + 6 + 6 + 6 + 6 + 6 + 6 = 6 × 7 = 42
Still by the same token,
2 + 2 + 2 + 2 = 2 × 4
In algebra, 2 × 4 can be written as (2)(4)
