Answer:
- 7Step-by-step explanation:
x ← a number
7x ← seven times the number
x - 42 ← forty-two less than the number
Seven times a number is forty-two less than the number.
7x = x - 42
-x -x

What are the solution(s) of x2-4-0?
X=-4 or X-4
X=-2 or X= 2
X=2
X=4
Answer:
X = - 2 or X = 2
Step-by-step explanation:
*completing the square*
X^2 - 4 = 0
X^2 = 4
X = +-√4
x = +-2
x= -2, 2
*factoring*
X^2 - 4 = 0
(x-2)(x+2) = 0
|. |
x = 2, x = -2
________________________________
(x-2)(x+2) = x(x+2) - 2(x+2) = x^2 + 2x - 2x - 4 = x^2-4
Solve for x.
x/2 = -5
x = 5/2
x = -5/2
x = -10
Answer:
x = -10
Step-by-step explanation:
x/2 = -5
Multiply each side by 2
x/2 * 2 = -5 *2
x = -10

Frank liked to buy packs of baseball cards. On 3 different days, he bought 3 packs. On 3 other days, he bought 4 packs each day. After that he split his packs with his 2 brothers. How many packs will they each have? Choose the expression that best matches this situation. [(3 x 3) + (4 x 3)] ÷ 3 [(3 x 3) + (4 x 3)] - 3 (3 x 3) + [(4 x 3) ÷ 3] [(3 x 3) + (4 x 3) ÷ 3]
Answer:
[(3 x 3) + (4 x 3)] ÷ 3
Step-by-step explanation:
Choose the expression that best matches this situation.
[(3 x 3) + (4 x 3)] ÷ 3
[(3 x 3) + (4 x 3)] - 3
(3 x 3) + [(4 x 3) ÷ 3]
[(3 x 3) + (4 x 3) ÷ 3]
On 3 different days, he bought 3 packs
= 3 × 3
= 9 packs
On 3 other days, he bought 4 packs each day.
= 4 × 3
= 12 packs
After that he split his packs with his 2 brothers
= (9 + 12) / 3
= 21 / 3
= 7 packs each for him and his two brothers
Here is the expression:
[(3 x 3) + (4 x 3)] ÷ 3
= (9 + 12) ÷ 3
= 21 / 3
= 7 packs

purchased song costs $1.19. How many songs must be purchased for the monthly price of
Napster to be the same as iTunes?
Answer:
It will take 100 purchased songs for iTunes and Napster to equal in price.
Step-by-step explanation:
iTunes: y=1.29x
Napster: y=1.19x+10
1.29x=1.19x+10
10=.10x
x=100

Give the algebraic expression for each of the following:
The sum of 20 and a number, m
Answer:
The sum of 20 and a number,m = 20+m
Factorize the given expression and divide them as directed.
[tex](m^{2} -5m +6) divided (m-2)[/tex]
We have to find :
m² - 5m + 6 / (m - 2) = ?First of all, we need to factorize
(m² - 5m + 6)⭆ m² - 5m + 6
⭆ m² - (3 + 2)m + 6
⭆ m² - 3m - 2m + 6
⭆ m(m - 3) - 2(m - 3)
⭆ (m - 2) (m - 3)
★ Division :
➠ m² - 5m + 6 / (m - 2)
➠ (m - 2) (m - 3) / (m - 2)
➠ (m - 3) [Final answer][tex].[/tex]

can someone tell me how to solve translations please?
Step-by-step explanation:
Hey there!
Here; The coordinates are ; H(-4,-2), G(-5,3), F(-2,1)
The translation P(x,y) = P'(X+7,y)
Use same formula.
H(-4,-2) -------> P'(3,-2)
G(-5,3)-----------> G'(2,3)
F(-2,1)------------> F'(5,1)
Therefore, the answer is Option C.
