Suppose ADEF is the image of a translation of AABC. If D is at (-6, -2), what translation rule maps 4ABC to ADEF?
Answer: D. T <-9, -2> (ΔABC) = ΔDEF
Step-by-step explanation:
D = A
A (3, 0) --> D (-6, -2)
To get the x-coordinate of D, you add -9 to 3
To get the y-coordinate of D, you add -2 to 0
T <-9, -2> (ΔABC) = ΔDEF

find the value of x
x=
Answer:
The value of x is 3
Step-by-step explanation:
Here, we want to find the value of x
to do this, we apply the principle of similar triangles
That would work as follows;
4/x + 5 = 7/(2x + x + 5)
4/x + 5 = 7/3x + 5
4(3x + 5) = 7(x + 5)
12x + 20 = 7x + 35
12x - 7x = 35-20
5x = 15
x = 15/5
x = 3

[tex] {2}^{x} - {3}^{x} = \sqrt{ {6}^{x} } - \sqrt{ {9}^{x } } [/tex]
Answer:
x = 0
Step-by-step explanation:
[tex]{2}^{x} - {3}^{x} = \sqrt{ {6}^{x} } - \sqrt{ {9}^{x } } \\ \\ {2}^{x} - {3}^{x} = \sqrt{ {6}^{x} } - \sqrt{ {( {3}^{2}) }^{x } } \\ \\ {2}^{x} - {3}^{x} = \sqrt{ {6}^{x} } - \sqrt{ {({3)}^{2x}}}\\ \\ {2}^{x} - \cancel{{3}^{x}} = \sqrt{ {6}^{x} } - \cancel{ {3}^{x} } \\ \\ {2}^{x} = \sqrt{ {6}^{x} } \\ squaring \: both \: sides \\ \\ {( {2}^{x} )}^{2} = {(\sqrt{ {6}^{x} })}^{2} \\ \\ {2}^{2x} = {6}^{x} \\ \\ {2}^{2x} = {(2 \times 3)}^{x} \\ \\ {2}^{2x} = {2 ^{x} \times 3}^{x} \\ \\ \frac{ {2}^{2x} }{ {2}^{x} } = 3^{x} \\ \\ {2}^{2x - x} = {3}^{x} \\ \\ {2}^{x} = {3}^{x} \\ \\ \frac{ {2}^{x} }{ {3}^{x} } = 1 \\ \\ \bigg( \frac{2}{3} \bigg)^{x} = 1 \\ \\ \implies \: x = 0 \\ \\ \because \: for \: x = 0 \\ \\ \bigg( \frac{2}{3} \bigg)^{0} = 1[/tex]
In his last football game, Sean rushed for 89 yards. If his season total is 871 yards, how many total yards did he have prior to his last game?
Answer:

3a² - 24ab + 48b² = 3 ( a - 4b )²
Step-by-step explanation:We will start by rewriting the given quadratic polynomial,
3a² - 24ab + 48b²
Taking out the common "3",
=> 3 ( a² - 8ab + 16b² )
Splitting the middle term i.e. " - 8ab " appropriately,
=> 3 ( a² - 4ab - 4ab + 16b² )
=> 3 [ a ( a - 4b ) - 4b ( a + 4b ) ]
=> 3 ( a - 4b ) ( a - 4b )
Hence, option C is correct.
Answer:
[tex]\huge\boxed{\tt{ 3 (a-4b)(a-4b)}}[/tex]
Step-by-step explanation:
[tex]\sf 3a^2-24ab+48b^2\\\\Taking \ 3 \ as \ common\\\\= 3 (a^2-8ab+16b^2)\\\\= 3 [(a)^2 - 2 (a)(4) + (4b)^2]\\\\Using \ Formula \ a^2 - 2ab + b^2 = (a-b)^2\\\\= 3 (a-4b)^2\\\\= 3 (a-4b)(a-4b)\\\\\rule[225]{225}{2}[/tex]

Answer:
3/4
Step-by-step explanation:
f(0) - f(3) / 0 - 3
f(0) = -4
f(3) = 9/4 - 16/4 = -7/4
f(0) - f(3) = [-4 - (-7/4)]
f(0) - f(3) = [-16/4 + 7/4]
f(0) - f(3) = -9/4
-9/4 ÷ -3 = -9/4 · -1/3 = 3/4

Answer:
541.1 square feet
Step-by-step explanation:
A = πr²
1) convert in. to ft because answer is in sq. ft
78 in => 6.5 ft
2) Find radius of entire area
6.5 ft + radius of inner circle
6.5 + 10 = 16.5
3) Calculate area of combined circles
A = π(16.5)²
A = 855.3 sq. ft
4) Find area of inner circle
A = π(10)²
A = 314.2 sq. ft
5) Subtract area of inner circle from combined area
855.3 sq ft - 314.2 sq. ft = 541.1 sq. ft
