Answer:
x = 0, 9/2
Step-by-step explanation:
6x^2 - 27x = 0 (original)
3x(2x - 9) = 0 (factor out GCF of 3x)
|
v
(solve each factor (3x and 2x - 9) for x)
3x = 0
x = 0
2x - 9 = 0
2x = 9
x = 9/2

5. You are taking a math quiz and need to complete at least 10 Geometry problems
and Algebra problems within 120 minutes. It will take you 15 minutes for each
Geometry problem and 10 minutes for each Algebra problem. Which system of
inequalities can be used to determine the amount of a, Algebra problems, and g,
Geometry problems you can complete.
Answer: 15g+10a(less than or equal to <) 120
2g+3a<10
The system of inequalities that can be used to determine the amount of geometry problems (g) and algebra problems (a) is:
[tex]a + g \geq 10[/tex]
[tex]10a + 15g \leq 120[/tex]
We can translate the given situation into inequalities to get the system of inequalities that we can use to find the amount of algebra and geometry problems that can be completed.
Thus:a = amount of algebra problems
g = amount of geometry problems
Therefore, the inequality that at least 10 geometry and algebra problems will be:[tex]a + g \geq 10[/tex]
Thus:
15 minutes for each geometric problem = 15g
10 minutes for each algebra problem = 10a
If all is intended to be taken within 120 minutes, therefore, the inequality that represents this will be:[tex]10a + 15g \leq 120[/tex]
Therefore, the system of inequalities that can be used to determine the amount of geometry problems (g) and algebra problems (a) is:
[tex]a + g \geq 10[/tex]
[tex]10a + 15g \leq 120[/tex]

If MP = 5.9, what is RN?
Answer:
A
Step-by-step explanation:
It would be A, because the two bisector lines that cut through this trapezoid are the same length, so 5.9-4.1=1.8. So the length of RN would be 1.8. Hope this helps!

Mason owns a trucking company. For every truck that goes out, Mason must pay the driver $13 per hour of driving and also has an expense of $1 per mile driven for gas and maintenance. On one particular day, the driver drove an average of 30 miles per hour and Mason's total expenses for the driver, gas and truck maintenance were $258. Write a system of equations that could be used to determine the number of hours the driver worked and the number of miles the truck drove. Define the variables that you use to write the system.

the angles of a triangle have measures of 78 degrees, 73 degrees, and 29 degrees. Which of the following be the measure of an exterior angle of a triangle?
A = 151 degrees.
B=141 degrees.
C=117 degrees.
D=112 degrees
Answer:
It's A.
Step-by-step explanation:
Extorior angles are 2 angles which match together which means 1 angle from outside the triangle matches with another angle in the triangle and form 180 degrees.
Use 180 and minus 78, 73 and 29 degrees separately. Do it until one of your answers match one of the options.

2. Write a quadratic function that has -intercepts (- 3, 0) and (4, 0) and passes through the point (5, 8)
Answer:
[tex]f(x)=x^2-x-12[/tex]
Step-by-step explanation:
Quadratic Function
Standard Form of Quadratic Function
The standard representation of a quadratic function is:
[tex]f(x)=ax^2+bx+c[/tex]
where a,b, and c are constants.
When the zeros of f (x1 and x2) are given, it can be written as:
f(x)=a(x-x1)(x-x2)
Where a is a constant called the leading coefficient.
We are given the two roots of f: x1=-3 and x2=4, thus:
f(x)=a(x+3)(x-4)
We also know that f(5)=8, thus:
f(5)=a(5+3)(5-4)=8
Operating:
a(8)(1)=8
Solving:
a=1
The function is:
f(x)=1(x+3)(x-4)
Operating:
[tex]\boxed{f(x)=x^2-x-12}[/tex]
Write the ratio as a fraction in simplest form, with whole numbers in the numerator and denominator.

Answer:
The given equation is of the form
p( x+ q)² + r = [tex]3((x+(-\frac{7}{6})^{2} +(-\frac{61}{12})[/tex]
Step-by-step explanation:
Step(i):-
Given equation 3 x² - 7 x -1
= [tex]3(x^{2} -\frac{7}{3} x )-1[/tex]
= [tex]3(x^{2} -2 X \frac{7}{3X2} +(\frac{7}{6} )^{2}-(\frac{7}{6} ^{2} )-1[/tex]
= [tex]3(x^{2} -2 X \frac{7}{6} +(\frac{7}{6} )^{2}-(\frac{49}{36} )) -1[/tex]
Step(ii):-
We know that formula
(a-b)² = a² - 2ab + b²
[tex]3x^{2} -7x-1 = 3((x-\frac{7}{6})^{2} -( 3X\frac{49}{36} )) -1[/tex]
[tex]3x^{2} -7x-1 = 3((x-\frac{7}{6})^{2} -\frac{61}{12}[/tex]
Final answer:-
The given equation is of the form
p( x+ q)² + r = [tex]3((x+(-\frac{7}{6})^{2} +(-\frac{61}{12})[/tex]
Kelsey knit a total of 6 centimeters of scarf over 2 nights. After 4 nights of knitting, how many centimeters of scarf will Kelsey have knit in total? Assume the relationship is directly proportional.
Answer:
[tex]12[/tex] cm
Step-by-step explanation:
If Kelsey knit a total of [tex]6[/tex] cm of scarf over [tex]2[/tex] nights, then we know that she can knit [tex]\frac{6}{2}=3[/tex] cm each night. Therefore, after [tex]4[/tex] nights of knitting, Kelsey would have knit a total of [tex]3*4=12[/tex] cm of scarf in total. Hope this helps!
