Answer:

It doesn't show what the drop down is. However, both of those are linear expressions.

Sergio's expressionn siplifies to: 9+3x (because two minuses cancel each other).

Leon's expression cancels to 12+6x (because 9+3=12)

Step-by-step explanation:

You have to show the dropdown to be able to answer exactly what they are looking for as an answer.

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.

Answers

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]

(i have the answer for part i, i just need hel with ii and iii)

Answers

Answer:

(-1, -5), (-1/2, -3), (-1, -9)

Step-by-step explanation:

The function in vertex form is:

f (x) = a(x - h)² + k, where (h, k) is the vertexf(x) = (x - 1)² - 3

i) y = f(x) - 2 = (x - 1)² - 3 - 2 = (x - 1)² - 5 ⇒ h = 1, k = -5

Minimum point:

(- 1, -5)

ii) y = f(2x) = (2x - 1)² - 3 = 4(x - 1/2)² - 3 ⇒ h = 1/2, k = -3

Minimum point:

(-1/2, -3)

iii) y = 3f(x) = 3((x - 1)² - 3) = 3(x - 1)² - 9 ⇒ h = 1, k = -9

Minimum point:

(-1, -9)

The list below shows all the possible outcomes for tossing a coin and rolling a 1 to 6 number cube. What is the probability that Max tosses heads and rolls a number greater than 2

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]

Solve 3-4/7 with steps pls

Answers

Since there are multiple steps, we would use PEMDAS. Since dividing comes before subtracting, we would divide -4/7 first.
-4/7= −0.571428571428571
Since it’s a really big decimal, we’re going to round it to the nearest hundredth. That would get you -0.57
Next we would do 3-0.57
3-0.57= 2.43

So your answer would be 2.43

Hope it helps :)
