Solve the equation : (3.2y-1.8)-(5.2y+3.4)=-5.8
Answer:
y = 0.3
Step-by-step explanation:
[tex](3.2y-1.8)-(5.2y+3.4)=-5.8 \\ \\ = 3.2y - 1.8 - 5.2y - 3.4 = - 5.8 \\ \\ 3.2y - 5.2y - 1.8 - 3.4 = - 5.8 \\ \\ - 2y - 5.2 = - 5.8 \\ \\ - 2y = 5.2 - 5.8 \\ \\ - 2y = - 0.6 \\ \\ y = \frac{ - 0.6}{ - 2} \\ \\ y = 0.3[/tex]
Answer
y= -11/2
Explanation
3.2y-+1.8-5.2y-3.4=-5.8
Collect like terms
-2y-5.2=-5.8
Move the constant to the right
-2y=5.8+5.2
Calculate
-2y=11
Divide
y=-11/2
Graph the line with slope
1/2 and y-intercept -9
Answer:
Step-by-step explanation:
slope is the x axis and y intercept is the y axis
so 1/2 will go on the x axis and -9 will go on the y axis
1/2 uses the rise over run method
Answer:
Answer is in the screenshot. The equation for the line is y=1/2 x - 9
Step-by-step explanation:
To graph a line when you know the slope and y intercept, you make a point on the y intercept. Your y intercept iIs -9 so you would make a point on (0,-9).
After you have the point on (0,-9) you use the slope to create the rest of your line. Slope is just Rise
Run
Your slope is 1/2. That means your next point on the line is up 1 unit and right 2 units. The next point on the line is (2,-8).

Marlon saves Php 4.50 on Monday, Php 7.25 on Tuesday, Php 5.55 on Wednesday, Php 3.95 on Thursday, and Php 8.15 on Friday from his daily transportation allowance for 3 weeks. From these savings, he wants to buy a 3-layered lunch box which costs Php 195.75. How much more must he save?
A) Php 107.55
B) Php 8.20
C) Php 29.40
D) Php 170.55
Answer: Php 107.55
Step-by-step explanation:
From the question, Marlon saves Php 4.50 on Monday, Php 7.25 on Tuesday, Php 5.55 on Wednesday, Php 3.95 on Thursday, and Php 8.15 on Friday . The Total amount saved will be:
= 4.50 + 7.25 + 5.55 + 3.95 + 8.15
= 29.40
Amount saved for 3 weeks will be:
= 29.40 × 3
= 88.20
Since the lunch box he wants to buy costs Php 195.75 and he has saved Php 88.20. The remaining amount will be:
= 195.75 - 88.20
= 107.55
if angle a = (7x-27) and angle b = (3x + 29) , then find the value of x.
Answer:
x = 14
Step-by-step explanation:
7x - 27 = 3x + 29
Subtract 3x from both sides;
4x - 27 = 29
Add 27 to both sides;
4x = 56
Divide both sides by 4;
x = 14

22. l = 12m
b = 10m
Perimeter = 2(l + b)
= 2(12 + 10)
= 24 + 20
= 44m
Area = l×b
= 12 × 10
= 120m²
(a) Fencing required = 44m
Cost per metre = $12
Cost for the fencing of 44m = 12 × 44
= $528
(b) Levelling required = 120m²
Cost per metre² = $50
Cost for the levelling of 120m² = 120 × 50
= $6000

Which system of equations can you use to find the roots of the equation 2x3 + 4x2 – x + 5 = –3x2 + 4x + 9? y = 2x3 + x2 + 3x +5 y =9 y = 2x3 + x2 y = 3x + 14 y = 2x3 + 4x2 – x + 5 y = –3x2 + 4x + 9
Answer:The answer is y = 2x3 + 4x2 – x + 5 and y = –3x2 + 4x + 9
Roots are both: x=-4, x= -1/2 , x= 1
Proof:
Solve for x over the real numbers:
2 x^3 + 4 x^2 - x + 5 = -3 x^2 + 4 x + 9
Subtract -3 x^2 + 4 x + 9 from both sides:
2 x^3 + 7 x^2 - 5 x - 4 = 0
The left hand side factors into a product with three terms:
(x - 1) (x + 4) (2 x + 1) = 0
Split into three equations:
x - 1 = 0 or x + 4 = 0 or 2 x + 1 = 0
Add 1 to both sides:
x = 1 or x + 4 = 0 or 2 x + 1 = 0
Subtract 4 from both sides:
x = 1 or x = -4 or 2 x + 1 = 0
Subtract 1 from both sides:
x = 1 or x = -4 or 2 x = -1
Divide both sides by 2:
Answer: x = 1 or x = -4 or x = -1/2
Step-by-step explanation:
The answer is y = 2x3 + 4x2 – x + 5 and y = –3x2 + 4x + 9
Roots are both: x=-4, x= -1/2 , x= 1
Explanation:
Solve for x over the real numbers:
2 x^3 + 4 x^2 - x + 5 = -3 x^2 + 4 x + 9
Subtract -3 x^2 + 4 x + 9 from both sides:
2 x^3 + 7 x^2 - 5 x - 4 = 0
The left hand side factors into a product with three terms:
(x - 1) (x + 4) (2 x + 1) = 0
Split into three equations:
x - 1 = 0 or x + 4 = 0 or 2 x + 1 = 0
Add 1 to both sides:
x = 1 or x + 4 = 0 or 2 x + 1 = 0
Subtract 4 from both sides:
x = 1 or x = -4 or 2 x + 1 = 0
Subtract 1 from both sides:
x = 1 or x = -4 or 2 x = -1
Divide both sides by 2:
Answer: x = 1 or x = -4 or x = -1/2

A spotlight has a beam that travels 100 feet and covers an area intercepted by an 84°
angle, as shown
What is area covered by the beam to the nearest square foot?
31416 satt
184 sq.ft
7330 sq.ft
26389 sq.ft
Answer:
7330 sq.ft
Step-by-step explanation:
Area covered by the beam = Area of sector
Area of sector = [tex] \frac{\theta}{360} \times \pi r^2 [/tex]
Where,
[tex] \theta = 84° [/tex]
Radius (r) = 100 ft
Plug in the values into the formula
Area of sector = [tex] \frac{84}{360} \times \pi 100^2 [/tex]
Area of sector = [tex] \frac{84 \times \pi \times 10,000}{360} [/tex]
Area of sector = 7,330 ft² (nearest square foot)

Answer:

Step-by-step explanation:
determine if l || m based on the information given on the diagram. If yes, state the converse that proves the lines are parallel.
Answer/Step-by-step explanation:
1. YES.
Converse: If same side interior angles are supplementary, then l || m. (Same side interior angles)
Since the sum of the two same side interior angles, 65° and 115°, equals 180°, therefore, l || m.
2. YES.
Converse: if two angles angles are a linear pair, they are supplementary, therefore l || m. (Linear pair)
Thus,
128° + 53° = 180°.
3. YES.
Converse: if two angles are corresponding angles and congruent, therefore l || m. (Corresponding angles).
Thus,
The indicated angles which are equal to 90°, are corresponding angles therefore, l || m.
4. YES
Converse: if two alternate exterior angles are congruent, then l || m. (Alternate exterior angles)
Thus, the two exterior angles are congruent, therefore l || m.
The converse which would serve as prove that l is parallel to m are given in the answers below:
Considering the information in the given diagrams:
1. Yes, l is parallel to m.
The converse is: "If corresponding angles are equal, then l is parallel to m". One of the corresponding angles plus [tex]115^{o}[/tex] equals [tex]180^{o}[/tex].
Thus, l || m.
2. Yes, l is parallel to m.
The converse is: "if two angles are linear pair, then they sum up to [tex]180^{o}[/tex]".
So then, l || m.
3. Yes, l is parallel to m.
The converse is: "if two corresponding angles are right angles, then they are congruent".
Therefore, l || m.
4. Yes, l is parallel to m.
The converse is: :if two alternate exterior angles are congruent, then l is parallel to m".
Therefore, l || m.
