what is the image point of (8,-7) after a translation right 1 unit and up 4 units?
Answers
Answer:
It is (9,-3) because x increased by 1 unit and y increased by 4 units.
Answer:
[tex](9,-3)[/tex]
Step-by-step explanation:
[tex](8,-7)[/tex]
If it moves right, add the value to the x-coordinate. If it moves left, subtract the value from the x-coordinate. In this case, because the point was translated 1 unit right, we add 1 to the x-coordinate 8.
[tex](9,-7)[/tex]
If it moves up, add the value to the y-coordinate. If it moves down, subtract the value from the y-coordinate. In this case, because the point was translated 4 units up, we add 4 to the y-coordinate.

A rectangular soccer field may have a width between 50 and 100 yards and a length
between 100 and 130 yards. One particular soccer field has a perimeter of 320 yards. Its
length measures 40 yards more than its width. What are the dimensions of this field?
The length is___yards.
The width is____yards.
Answers
Answer:
[tex]perimeter = 2(l + w) \\ but \: length = 40 \times width \\ perimeter = 2(40w + w) \\ p = 2(41w) \\ 320 = 2(41w) \\ w = \frac{320}{(2 \times 41)} \\ w = 3.902 \: yards \\ length = 40 \times w \\ = 40 \times 3.902 \\ l = 156.08 \: yards[/tex]
9514 1404 393
Answer:
length: 100 yardswidth: 60 yardsStep-by-step explanation:
Let w represent the width of the field. Then the length is (w+40), and the perimeter is ...
P = 2(L +W)
320 = 2((w+40) +w) . . . . fill in values
160 = 2W +40 . . . . . . . . . divide by 2, collect terms
80 = w +20 . . . . . . . . . . . divide by 2
60 = w . . . . . . . . subtract 20
w+40 = 100
The length is 100 yards; the width is 60 yards.

Jade has 100 to spend on shoes and socks. She buys a pair of shoes for 75 and wants to wants to spend the rest of the money on socks. Each of socks cost $3.50. let n represent the number of the pair of socks that jade can buy. Which inequality represents her situation?
Answers
Answer:
75 + 3.5n ≤ 100
Step-by-step explanation:
Given that:
Total amount = $100
Cost of shoe = $75
Cost per socks = $3.50
n = number of socks pairs
Cost of shoe + (cost per pair of socks * number of socks) ≤ total amount
75 + (3.50 * n) ≤ 100
75 + 3.5n ≤ 100

(3x-2y=-16)first put in standard form y=mx+b
(-2y=-3x-16) divide both sides by -2
y=3/2x+8
Answer:
C
Step-by-step explanation:
By opposite I'm going to assume they mean the perpindicular line
To do this you first need to convert the function into linear form
So we have 3x-2y=-16
and so we can add 2y and 16 to both sides to get
3x+16=2y
then divide by 2 to get
3/2x+8=y
This is our function in linear form but now we need the opposite by taking the negative reciprocal of the slope
This means our near equation is now -2/3x+8 while none of them give that as an option directly if you simplify C it will match

Step-by-step explanation:
Which equation shows one way to find the value of 45 × 4?
45 × 4
Splitting each number into factors of each other
45 = 9 × 5
4 = 2 × 2
45 × 4 = (9 × 5) × (2 × 2)
45 × 4 = (9 × 2) × (5 × 2)
45 × 4 = 18 × 10

slope and y intercept of 5x + 8y = 8
Answers
Answer:
Slope: -5/8
y intercept: (0,1)
Step-by-step explanation:
The slope of the line will be {m} = -5/8 and the y - intercept will be 1.
What is direct variation?Direct variation of a quantity {y} with respect quantity {x} means that the value of {y} increases as the the value of {x} increases. Mathematically -
y = Kx
K = y/x
where -
{K} is scale factor. It also tells by how many times is {y} greater than {x}.
Given is the equation of a straight line as -
5x + 8y = 8
We can rewrite the equation as -
5x + 8y = 8
8y = - 5x + 8
y = -(5/8)x + 1
So the slope will be -
m = -(5/8)
c = 1
Therefore, the slope of the line will be {m} = -5/8 and the y - intercept will be 1.

umm its B cause i got it right hope this helped :)
Step-by-step explanation:
Use the figures to complete the statements proving the converse of the Pythagorean theorem.
Drag and drop a phrase, value, or equation into the box to correctly complete the proof.
To prove the converse of the Pythagorean theorem, we must show that if △ABC has sides of a, b, and c such that a² + b² = c² , then △ABC is a right triangle.
Define △DEF so that it is a right triangle with sides a, b, and hypotenuse x. By the Pythagorean theorem, a² + b² = x² .
Since a² + b² = c² and a² + b² = x², it must be true that c² = x². Since sides of triangles are positive, then we can conclude that Response area. Thus, the two triangles have congruent sides and are congruent.
Finally, if △ABC is congruent to a right triangle, then it must also be a right triangle.

The opposite of -10·t and t - 10·t is t
Step-by-step explanation:
1) The opposite of 4·x and -5 + 4·x is given as follows;
-4·x + (-5 + 4·x) = -4·x -5 + 4·x = -4·x + 4·x - 5 = 0 - 5 = -5
2) The opposite of -10·t and t - 10·t is given as follows;
-(-10·t) + (t - 10·t) = 10·t + t - 10·t = 10·t - 10·t + t = 0 + t = t
3) The opposite of (-7 - 4·v) and -4·v is given as follows;
-(-7 - 4·v) + (-4·v) = -1 × (-7 - 4·v) - 4·v = 7 + 4·v - 4·v = 7 + 0 = 7
"The difference between four-fifths of
a number and 11 is -46."
Answers
Answer:
The number is -43.75.
Step-by-step explanation:
4x/5 - 11 = -46
4x/5 = -35
x = -43.75
Answer:
-43.75
Step-by-step explanation:
This is the answer because:
1) We know that 4/5 of a number has to equal -35 since -46 + 11 = -35.
2) 4/5x = -35 (solve for x): -35 ÷ 4/5 = -43.75
3) 4/5 x -43.75 = -35, I got this by solving for x (look at step 2)
Therefore, the answer is -43.75

Determine whether the function f(x) = -9.5 + 6 + x² is even, odd or neither.
Answers
Answer:
The function f(x) = -9.5 + 6 + x² is neither odd or even.
Step-by-step explanation:
We know that a function is termed as 'even' when
f(-x) = f(x) for all x
We know that a function is termed as 'odd' when
f(-x) = -f(x) for all x
Given the function
f(x) = -9.5x⁵ + 6 + x²
substitute x with -x
f(-x) = -9.5(-x)⁵ + 6 + (-x)²
as (-x)⁵ = -x⁵, so
f(-x) = -(-9.5x)⁵ + 6 + (-x)²
Apply exponent rule: (-a)ⁿ = aⁿ, if n is even
f(-x) = -(-9.5x)⁵ + 6 + x²
Apply rule: -(-a) = a
f(-x) = 9x⁵ + 6 + x²
As
f(-x) ≠ f(x) ≠ -f(x)
Therefore, the function f(x) = -9.5 + 6 + x² is neither odd or even.

1.5(2y + 5) = 36 ( divide both sides by 1.5 )
2y + 5 = 24 ( subtract 5 from both sides )
2y = 19 ( divide both sides by 2 )
y = [tex]\frac{19}{2}[/tex] = 9.5
