Answer:
h(x+2)= x² +5
Step-by-step explanation:
h(x)= x² +5 -2x
h(x+2)= (x+2)² +5 - 2(x+2)
h(x+2)= x² +4x+4+5-4x-4
h(x+2)= x² +5
Enter the solution (x, y) to the system of equations shown
x = 2.5
5y + 2x = -10
Answer:
x=2.5, y=-5. (2.5, -5).
Step-by-step explanation:
5y+2(2.5)=-10
5y+5=-10
5y=-10-5
5y=-15
y=-15/5
y=-5
Answer:
(2.5, -3)
Step-by-step explanation:
We are told up front that x = 2.5. Substituting 2.5 for x in the second equation, we get:
5y + 2(2.5) = -10.
Carrying out the indicated multiplication:
5y + 5 = -10.
Then 5y = -15, and y = -3.
The solution in the form (x, y) is (2.5, -3).

Answer:
1. m∠B=110°
2. 560 cm3
3. Numerical data
4. 2000 cm3
5. 50%
Step-by-step explanation:
1. The explanation of part 1 is given in the attachment.
2. Given dimensions : 10 cm, 8 cm, and 7 cm.
Let Length of cuboid =10 cm
breadth/width of cuboid =8 cm
height of cuboid = 7cm
Volume of cuboid = length *width* height
=( 10 *8*7) cm3
=(560) cm3
3. Age, Birth date and weight are the types/examples of "Numerical Data" because these all are describe in terms of numeric values.
4. 1 liter = 1000 cm3 or 1 cm3 = 0.001 liter
1.5 liters =(1.5*1000) cm3 = (15*100) =1500 cm3
1 dm3 =1000 cm3
0.35 dm3 = (0.35*1000) cm3 = (35*10) cm3 =350 cm3
Given expression: 1.5 litre + 0.35 dm3 + 150 cm3 = cm3
1500 cm3 + 350 cm3 +150 cm3 = 2000 cm3
5. If A=(1/2)B, then B : A = 50 %
Ratio: B : A
B : (1/2) B
1: (1/2)
50 % (The value of A is half of the value of B)
what's (-1,4), y=3x+5?
Answer:
(-1,4)
-1 is x and 4 is y
You have to plug it in for the equation:
4= 3(-1)+5
4= -3+5
4 = 2
the answer is no solution because 4 does not equal to 2

Question 2) An online gaming club has a one-time registration fee of $14.95 and charges $0.69 to buy each game. If Sammy has $60.00
to join the club and buy games, what is the maximum number of games she can buy?
B
66
°C 108
D
109
PLEASE HELP
Answer:
the answer is b beacause
Step-by-step explanation:
when you multiply 14.95 times 6 it equals b
Answer: 65
Step-by-step explanation:
Let the number of games be x, this means that the cost of x games will be 0.69x.
There is also a one-time registration fee of $14.95 , this means that for Sammy to register and buy game with $60 , the equation will be
14.95 + 0.69x =60
subtract 14.95 from both sides
0.69x = 60 - 14.95
0.69x = 45.05
divide through by 0.69
x = 45.05/0.69
x = 65.28985507
Therefore , the maximum number of games she can buy is 65
4²+2²-(-3²)=m²-(-1²)+(√3)²
Answer:
m = ± 5
Step-by-step explanation:
Given
4² + 2² - (- 3²) = m² - (- 1²) + ([tex]\sqrt{3}[/tex])² ← evaluate exponents
noting that - 3² = - 9 and - 1² = - 1
16 + 4 - (- 9) = m² - (- 1) + 3, that is
20 + 9 = m² + 1 + 3
29 = m² + 4 ( subtract 4 from both sides )
25 = m² ( take the square root of both sides )
m = ± 5
A rectangle has a width of 6 units and a length of 2x+8 units. If the area is 108 units squared, what is the value of x?
Answer:
x=5
Step-by-step explanation:
let, width of rectangle=b=6 units
length of rectangle=l=2x+8
given area of rectangle=108 units squared
area of rectangle=lb
108=(2x+8)6=12x+48
108-48=12x

find the 30th term of the arithmetic sequence with a first term of 4 and a comman difference of 8
Answer:
236
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 4 and d = 8, thus
[tex]a_{30}[/tex] = 4 + (29 × 8) = 4 + 232 = 236

The rate that The price increased from the original price to today
Answer:
700%
Step-by-step explanation:
The price increased from $0.30 to $2.40. What is the rate of increase, in percentage?
We can use the formula shown below:
[tex]\frac{New-Old}{Old}*100[/tex]
Where
New Price is 2.40 and the Old Price is 0.30
We substitute and calculate:
[tex]\frac{New-Old}{Old}*100\\\frac{2.40-0.30}{0.30}*100\\=7*100\\=700[/tex]
Hence,
Price increased 700%
