Answer:
4. C
5. 7
6. 3
Step-by-step explanation:
Four:
You have to multiply both of them. Just easy math!
Five:
This one is more complicated. You can see that it is asking you to plug in for a,
F(3):
F(1.25):
So now just subtract the answers. 7-0 equals 7.
Six:
Just look at the graph and see what number corresponds with y(6), or the 6 on the y axis. It appears to be three.
Have a nice day! Hope this helps. Don't forget to mark brainliest!
X^2 + 3x - 4 = 6
x^2 + 3x - 10 = 0 (Now reverse FOIL)
(x + 5)(x - 2)(Now x will equal the opposites of your numbers)
x = -5
x = 2
Hope this helped!
Answer:
The answer to your question is the letter B. x = 6
Step-by-step explanation:
Data
4x² - 48x = -144
Process
1.- Equal to zero
4x² - 48x + 144 = 0
2.- Multiply 4 by 144
4 x 144 = 576
3.- Find the prime factors of 576
576 2
288 2
144 2
72 2
36 2
18 2
9 3
3 3
1
4.- Find two numbers that added gives -48,
these numbers are -24 and -24
5.- Write the equation using these numbers
4x² -24x - 24x + 144 = 0
6.- Factor by grouping
4x(x - 6) - 24(x - 6)
7.- Factor by like terms
(x - 6)(4x - 24)
8.- Find the solutions
x - 6 = 0 4x - 24 = 0
x = 6 4x = 24
x = 24/4
x = 6
The transformation is a reflection
Answer:
The answer to your question is:
m = length of the smaller bed = 17 ft
l = length of the larger bed = 25 ft
Step-by-step explanation:
Data
A1 + A2 = 914
A1 - A2 = 336
A1 = l²
A2 = m²
Process
l² + m² = 914
l² - m² = 336
l² = 336 + m²
(336 + m²) + m² = 914
336 + 2m² = 914
2m² = 914 - 336
2m² = 578
m² = 578 / 2
m² = 289
m = 17 ft
l² = 336 + 289
l² = 625
l = 25 ft
