Answer:
x^2 - 16
Step-by-step explanation:
Answer:
x² - 16
Step-by-step explanation:
(x - 4)(x + 4)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x + 4) - 4(x + 4) ← distribute both parenthesis
= x² + 4x - 4x - 16 ← collect like terms
= x² - 16
Help me please answer thanks
At a restaurant, the cost for one breakfast taco and one glass of milk is $2.10.
The cost for two tacos and three glasses of milk is $5.15.
How much would it cost for 3 tacos and 4 glasses of milk
Answer: $7.25
Step-by-step explanation:
Let T = taco cost
Let M = milk cost
T + M = 2.10
2T + 3M = 5.15
Multiply the first equation by (-2) and add it to the second equation
-2T - 2M = -4.20
2T + 3M = 5.15
M = 0.95
Plug this value for M in to the first equation
T + 0.95 = 2.10
T = 1.15
So a taco costs $1.15 and the milk costs $0.95
1.15 * 3 = 3.45
0.95 * 4 = 3.80
3.45 + 3.80 = 7.25

Answer:
Step-by-step explanation:
1a. 2x - 4y = 2
-x + 4y = 3
x = 5
-5 + 4y = 3
4y = 8
y = 2
(5, 2)
1b. 2x + 3y=1
-2x + 2y = -6
5y = -5
y = -1
2x - 3 = 1
2x = 4
x = 2
(2, -1)
2a. x + 2y = 4
2x - 5y = -1
-2x - 4y = -8
2x - 5y = -1
-9y = -9
y= 1
2x - 5 = -1
2x = 4
x = 2
(2, 1)
2b. 4x + 2y = 4
x - 2y = -5
5x = -1
x= -1/5
-1/5 - 2y = -5
-2y = -4 4/5
y= 12/5
(-1/5, 12/5)
3. 5x + 3y = 85
11x + 5y = 163
25x + 15y = 425
-33x - 15y = -489
-8x = -64
x = 8 regular
5(8) + 3y = 85
40 + 3y = 85
3y = 45
y = 15 mini bouquets
(8 regular, 15 mini bouquets)
4a. 6x + 12y = -6
18x - 12y = - 162
24x = -168
x = -7
3(-7) - 2y = -27
-21 - 2y = -27
-2y = -6
y= 3
(-7, 3)
4b. 3(6 -y) - 2y = 38
18 - 3y - 2y = 38
18 - 5y = 38
-5y = 20
y = -4
x = 6 + 4
x = 10

Answer:
NM =LK=20cm(side of parallelogram are equal)
LN=KM=24cm(diagonal of parallelogram are equal)
QM=1/2×24=12cm(diagonal bisect each other)
KN=√(24²-20²)=13.26cm(by Pythagoras theorem)

A company makes steel rods shaped like cylinders. Each rod has a diameter of 8 centimeters and a height of 20 centimeters. If the company used 28,134.4 cm3 of steel, how many rods did it make?
Answer:
1,172.3 cm³
Step-by-step explanation:
Find the volume of one rod, then divide the total volume of steel used by the volume of one rod. The volume of one rod is
V = (πd²/4)h
d = 4 cm
h = 20 cm
Plugin the numbers and get V in cm³, then divide the given total volume of 28,134.4 cm³ by V. If the result is not an integer, then round down.
Add
20 + 4 = 24
Then
28,134.4 ÷ 24 = 1172.26
Rounded to the nearest 0.1 or the Tenths Place = 1,172.3
Therefore, 1,172.3 rods will be made per hour.

Jesse serve 13 pints of orange juice at her party. How many quarts of orange is that she serve? Jesse served ____ quarts and ____ pints.
Solve the system by substitution.
y = 5x
y = 9x + 4
Answer:
(-1, -5)
Step-by-step explanation:
[tex]\left \{ {{y=5x} \atop {y=9x+4}} \right.[/tex]
1. We must calculate x, for that we must substitute y, so we have:
5x=9x+4
2. Now we solve the equation.
5x-9x=4
-4x=4
x=-1
3. Now we must calculate y
y=5x
y=5(-1)
y=-5
And the answer is (-1, -5)

Solve for x. −12x+13>35 Drag and drop a number or symbol into each box to correctly complete the solution.
Answer:
x < -11/6.
Step-by-step explanation:
−12x + 13 > 35
-12x > 35 - 13
-12x > 22
Divide both sides by -12 and invert the inequality sign:
x < -22/12
x < -11/6.
