Which of the following is the graph of the solution set of t – 4 ≥ 4t + 8 or 3t >14 – 4t?
Answers
Answer:
Option (C)
Step-by-step explanation:
There are two inequalities,
t - 4 ≥ 4t + 8 ------(1)
3t > 14 - 4t ------(2)
By simplifying inequality (1),
t - 4 ≥ 4t + 8
t ≥ 4t + 8 + 4
t ≥ 4t + 12
t - 4t ≥ 12
-3t ≥ 12
t ≤ [tex]\frac{12}{(-3)}[/tex]
t ≤ -4
By solving inequality (2),
3t > 14 - 4t
3t + 4t > 14
7t > 14
t > [tex]\frac{14}{7}[/tex]
t > 2
From the given graphs, Option (C) will be the answer.

Andrea has a balance of $135.68 in her savings account. Every Friday Andrea goes to the bank to deposit $170.50 and withdraw (take out) $60. If she does this every Friday for 4 weeks, how much money does Andrea have in the bank? Show all work or explain how you got your answer.
Answers
Answer
577.68
Step-by-step explanation:
first you subtract 60 from 170.50 to get 110.5. After that you multiply by 4 to get 442. take 442 and add it to 135.68 to get 577.68. so it would look like this
170.500-60=110.5 110.5 x 4=442 442+135.68=577.68

Find the measure of each numbered angle
Answers
measure of angle 2 is 56
measure of angle 3 is 74
All triangle’s angles add up to 180
The measure of each numbered angles are ∠1 = 56°, ∠2 = 56° and ∠3 = 74°.
What is Angle?An angle for any figure is formed by two rays which joins at a common point called vertex or node.
Usually angles are measured in degrees or radians.
Consider triangle PMQ
The sum of the interior angles of a triangle is 180°.
∠MPQ + ∠QMP + ∠PQM = 180°
58° + 66° + ∠1 = 180°
∠1 = 180° - (58° + 66°)
∠1 = 180° - 124°
∠1 = 56°
Now, ∠1 and ∠2 are vertically opposite angles. Hence they are equal.
∠2 = 56°.
Again, for triangle NQO
∠2 + ∠3 + 50° = 180°
56° + ∠3 + 50° = 180°
∠3 = 180° - (50° + 56°)
∠3 = 180° - 106°
∠3 = 74°
Hence ∠1, ∠2 and ∠3 are 56°, 56° and 74° respectively.

Step-by-step explanation:
Given
36a² - 49b² ← this is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
Thus
36a² - 49b²
= (6a)² - (7b)²

The measure of exterior angle ∠CAD of a triangle ABC is 100°.
From the given figure, ∠ACB=80° and ∠ABC=20°.
What is an exterior angle theorem?The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.
From the given triangle,
m∠CAD=m∠ACB+m∠ABC
⇒ m∠CAD=80°+20°
⇒ m∠CAD=100°
Therefore, the measure of exterior angle ∠CAD of a triangle ABC is 100°.

OR
[tex]17^\circ F[/tex] decrease in the temperature.
Step-by-step explanation:
Given that:
Temperature at the night = [tex]12^\circ F[/tex]
Temperature in the morning = -[tex]5^\circ F[/tex]
To find:
The total difference in the temperature = ?

Can someone please how to do fractions in the lowest terms
Answers
Answer:
In order to out a fraction in lowest terms, you must divide by the Greatest Common Factor, or GCM, of the numerator and denominator in the fraction. Let's say we have the fraction 25/100. We know that the greastest common factor of 25 and 100 is 25, as 25 ÷ 25 = 1 and 100 ÷ 25 = 4 so 25/100 in lowest terms is 1/4:
25 25 1
___ ÷ ___ = ___
100 25 4
If the GCM of a fraction equals 1, the fraction is simplified. Because the only common factor of 1 and 4 is 1, we know this fraction is simplified.
1 1 1
__ ÷ ___ = ___
4 1 4
