In the equation, 23 + b= 456 the variable is what
Z varies jointly with x, and y, and z=7 when x= 2, y= 2
pleasee I need an answer now!!
Answer:
(7/4)(2)(2)=7
Step-by-step explanation:
Answer:
z = 1.75xy
Step-by-step explanation:
Given z varies jointly as x and y then the equation relating them is
z = kxy ← k is the constant of variation
To find k use the condition z = 7 when x = 2 and y = 2, then
7 = k × 2 × 2 = 4k ( divide both sides by 4 )
1.75 = k
z = 1.75xy ← equation of variation
What is the value ofx?
Answer:
x = 39
Step-by-step explanation:
∠JKL and ∠LKM are complementary angles meaning they have a sum of 90° Knowing this, we can create an equation to solve for x.
2x - 14 + 26 = 90
2x + 12 = 90
2x = 78
x = 39

Find the length of the third side. If necessary, write in simplest radical form. (15 POINTS!!)
Answer:
4
Step-by-step explanation:
perpendicular (p) = 4
hypotenuse (h) = 2√5
base (b) = ?
We know by using Pythagoras theorem
b = √(h² - p²)
= √ (2√5)² - 4²
= √ 16
= 4

Sunrise, a bed-and-breakfast hotel, charges a one-time deposit of $25 plus $85 per night. Another bed-and-breakfast hotel called Bright Eyes charges a flat rate of $95 per night. Craig wants to book a hotel for 5 nights.
Answer:
Sunrise $450 Bright Eyes $475
Step-by-step explanation:
Let x= number of days
Sunrise:
(25 + 85x)= total cost
(25+85(5))= $450
Bright Eyes:
(95x)= total cost
(95(5))= $475
The Bright eyes hotel would be more cost efficient than the Sunrise hotel.
What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Sunrise, a bed-and-breakfast hotel, that charges a one-time deposit of $25 plus $85 per night. Another bed-and-breakfast hotel called Bright Eyes charges a flat rate of $95 per night.
The total cost for 5 nights at Sunrise hotel would be -
C(s) = 25 + 85 x 5 = $450
The total cost for 5 nights at Bright eyes hotel would be -
C(b) = 95 x 5 = $475
Therefore, the Bright eyes hotel would be more cost efficient than the Sunrise hotel.

yes
no
Answer:
No because the sign does not have a line under it. The line means equal too
Step-by-step explanation:
The coordinates of one endpoint of a line segment are (4, −12). The length of the segment is 5 units. Determine four coordinate pairs that could serve as the other endpoint of the given line segment. Enter all four coordinate pairs in the box using a comma to separate each pair. For example: (0, 0), (1, 1), (2, 2), (3, 3)
Answer:
Four coordinate pairs that could serve as the other endpoint of the given line segment are given by: (9,-12), (-1,-12), (4,-7), (4,-17).
Step-by-step explanation:
One endpoint of (4,-12), length of 5 units.
Four possible pairs:
Add 5 to x, keep y: (4+5,-12) = (9,-12).
Subtract 5 from x, keep y: (4-5,-12) = (-1,-12).
Keep x, add 5 to y: (4,-12+5) = (4,-7)
Keep x, subtract 5 from y: (4,-12-5) = (4,-17)
Four coordinate pairs that could serve as the other endpoint of the given line segment are given by: (9,-12), (-1,-12), (4,-7), (4,-17).

A clear box has the shape of a rectangular prism and is filled with sand. Find the volume if the box
Answer:
24 m³
Step-by-step explanation:
Since you didn't state the dimensions of the rectangular prism, and you didn't add a picture to show it's dimensions, then permit me to assume dimensions for the question
Assuming it's breadth is 2 m.
Assuming it's length is 4 m.
Assuming it's height is 3 m
Then the volume of a rectangular prism is given as l * b * h. Which means we multiply all the sides by one another. From my assumption of values, we have that 2 * 3 * 4, and this gives us 24 m³
24 m
Now what you'd do is substitute your values for my assumed values.. Cheers

a^2+3a=7
Answer:
two unequal, complex roots
Step-by-step explanation:
Rewrite this quadratic as a^2 + 3a - 7 = 0. The coefficients are {1, 3, -7}. The discriminant is b^2 - 4ac = 3^2 - 4(1)(-7), or 9 - 28, or -19.
Because the discriminant is negative, we know immediately that this quadratic has two unequal, complex roots.
Solve the quadratic equation.
3x^2=81
Answer:
3x^2=81
x²=81/3
x=√27=3√3
Step-by-step explanation:
3x²=81
With this we have to square root both sides to find the value of x.
[tex] \sqrt{3 {x}^{2} } = \sqrt{81} [/tex]
So the x will cancel the square root sign so;
[tex]3x = \sqrt{81} [/tex]
And now we have to find the square root of 81 which is 9, because when we multiply 9 by 9 we are going to be get 81 so the square of 9 is 81 and the square root of 81 is 9
So;
[tex]3x = 9[/tex]
And then we divide both sides by 3 to find the value of x ;
[tex] \frac{3x}{3} = \frac{9}{3} [/tex]
[tex]x = \frac{9}{3} [/tex]
[tex]x = 3[/tex]

What is the remainder if f(x) = x^4- 5x2 - 6x - 10 is divided by x - 3?
A. 8
B. 44
C. -46
D. 224
Answer:
A) 8
Step-by-step explanation:
The remainder when f(x) = x⁴ + 0x³ - 5x² - 6x - 10 is divided by x - 3 is 18.
What is factor theorem?Factor theorem states that if x - a is a factor of f(x) then f(a) = 0.If f(a) ≠ 0 then x - a is not a factor of f(x).
To determine the remainder of f(x) = x⁴ + 0x³ - 5x² - 6x - 10 when divided by x - 3 which is x - 3 = 0 or x = 3 we have to replace the value of x in f(x).
∴ f(x) = x⁴ + 0x³ - 5x² - 6x - 10.
f(3) = (3)⁴ + 0(3)³ - 5(3)² - 6(3) - 10.
f(3) = 81 + 0 - 45 - 18.
f(3) = 18.
So, the remainder is 18.
