PLS HELP ME WITH THIS QUESTION!!!!!
Answer: 24
Step-by-step explanation:
Let the total number of problems be x.
After 15 minutes, [tex]x-\frac{1}{4}x=\frac{3}{4}x[/tex] problems are left.
After another 15 minutes, [tex]\frac{3}{4}x\left(1-\frac{1}{3})=\frac{3}{4}x\left(\frac{2}{3} \right)=\frac{1}{2}x[/tex] problems are left.
This is equal to 12, meaning x = 24.

point Find the length of segment CD with C(2,3) and D (-3, 15
Step-by-step explanation:
so, if the text is correct, the 2 points are
(2, 3) and (-3, 15).
the length of the line segment is the distance between both points.
did this we use Pythagoras for right-angled triangles.
c² = a² + b²
c is the Hypotenuse and the distance between both points. a and b are the legs (enclosing the 90 degree angle), which are simply the differences of the x and the y coordinates.
so,
distance² = (2 - -3)² + (3 - 15)² = 5² + (-12)² = 25 + 144 = 169
distance = sqrt(169) = 13 = length of line segment

fill in the blanks with <,>,= symbols( -3)+(-19)+6...................(-41)-15+9
[tex]( - 3) + ( - 19) + 6 \\ - 3 + ( - 19) + 6 \\ - 3 - 19 + 6 \\ = - 16[/tex]
#2[tex]( - 41) - 15 + 9 \\ - 41 - 15 + 9 \\ = - 47[/tex]
Now,[tex] - 16 > - 47[/tex]
How?When the number is in negative the smaller number is greater than the greater number.Answer:
(-3)+(-19)+6 [>] (-41)-15+9
Step-by-step explanation:
(-3)+(-19)+6= -16
and
(-41)-15+9= -47
so, -16 is greater than -47

Two positive numbers have a difference of 8. The larger number is two more than twice the smaller. Find the two numbers
Let the bigger number be 'p' and the smaller number 'p'.
Since the numbers have a difference of 8, then p - q = 8
& since the larger number is two more than twice the smaller, then
p = 2q + 2
⇒ (2q + 2) - q = 8 [by substituting for equation for p]
q = 6
Since q = 6,
⇒ p - 6 = 8
p = 14
∴ the smaller number is 6 and the bigger 14

Answer:
Step-by-step explanation:
Solve the equation for 0 and 1:
x^3 + 6x -5
Replace x with 0:
0^3 + 6(0) -5 = -5
Replace x with 1:
1^3 + 6(1) -5 = 1+6 -5 = 2
Because the value of f(0) is negative and the value of f(1) is positive then there is at least one value of x between 0 and 1 that f(x) = 0
