what is the value of this expression when x = -5 and y = -3 [tex]\frac{2}{3} x^{3} y^{2}[/tex]
Answer:
y = - 750
Step-by-step explanation:
Given
y = [tex]\frac{2}{3}[/tex] x³y² ← substitute x = - 5, y = - 3 into the expression
= [tex]\frac{2}{3}[/tex] × (- 5)³ × (- 3)²
= [tex]\frac{2}{3}[/tex] × - 125 × 9 ( cancel the 3 and 9 )
= 2 × - 125 × 3
= - 750

How do you solve x^2+5x-14=0
Answer:
x = -7 , x = 2
Step-by-step explanation:
[tex]x^2 + 5x -1 4= 0\\\\x^2 + 7x -2x - 14 = 0\\\\x(x + 7) -2(x + 7) = 0\\\\(x+7)(x-2) = 0\\\\x+ 7 = 0 , \ x - 2 = 0 \\\\x = - 7 , \ x = 2[/tex]
Answer:
x = - 7, x = 2
Step-by-step explanation:
Solve by factoring , that is
x² + 5x - 14 = 0
Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (+ 5)
The factors are + 7 and - 2 , since
7 × - 2 = - 14 and 7 - 2 = + 5 , then
(x + 7)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x - 2 = 0 ⇒ x = 2

Shawn and Dorian rented bikes from two different rental shops. The prices in dollars, y, of renting bikes from the two different shops for x hours is shown. Shop Shawn used: y=10+3.5x Shop Dorian used: y=6x If Shawn and Dorian each rented bikes for the same number of hours and each paid the same price, how much did each pay for the rental? Round to the nearest dollar if necessary. 3 4 14 24
Answer: 24
Step-by-step explanation:
Since we are given the information that
Shop Shawn used: y=10+3.5x while Shop Dorian used: y=6x.
To solve the question asked, we need to equate both equations together and this will be:
10 + 3.5x = 6x
6x - 3.5x = 10
2.5x = 10
x = 10/2.5
x = 4
Therefore, we can put the value of x into any of the equation to get y. This will be:
y = 6x
y = 6 × 4
y = 24
The amount paid for the rentals is 24

Answer:
x = [tex]7\sqrt{2}[/tex]
Step-by-step explanation:
a is the hypotenuse of the right angled triangle ehereas the other two sides are legs of a right angle triangle .
since the other two sides are equal both should be denoted as x.
now the value of a is given i.e 14 m
using pythagoras theorem,
pythagoras theorem states that sum of square of two smaller sides of a right triangle is equal to the sum of square of hypotenuse. so,
a^2 + b^2 = c^2
x^2 + x^2 = 14^2
2x^2 = 196
x^2 = 196/2
x^2 = 98
x = [tex]\sqrt{98}[/tex]
x = [tex]7\sqrt{2}[/tex]
Answer:
[tex]x=7\sqrt{2}[/tex]
Step-by-step explanation:
The given triangle is a right isosceles triangle. This means that it is a triangle with two congruent sides and a right angle (indicated by the box around one of the angles). One of the properties of a right isosceles triangle is that it follows the following sides-ratio,
[tex]x-x-x\sqrt{2}[/tex]
Where (x) represents the legs (sides adjacent to the right angle of a right triangle) or the congruent sides in this case. ([tex]x\sqrt{2}[/tex]) represents the hypotenuse or the side opposite the right angle. Form a proportion based on the given information and solve for the unknown value (x).
[tex]x=\frac{a}{\sqrt{2}}[/tex]
Substitute,
[tex]x=\frac{14}{\sqrt{2}}[/tex]
Simplify,
[tex]x=\frac{14}{\sqrt{2}}\\\\x=\frac{14*\sqrt{2}}{\sqrt{2}*\sqrt{2}}[/tex]
[tex]x=\frac{14\sqrt{2}}{2}[/tex]

Find any domain restrictions on the given rational equation:
X/2x+14 + x-4/6 = 3/x^2 + 2x -35. Someone please answer I’m doing summer school not tryna redo math AGAIN
Answer:
[tex]\dfrac{x}{2 \cdot x + 14} + \dfrac{x - 4}{6} = \dfrac{3}{x^2} + 2\cdot x - 35; Domain \ restriction \ x \neq 0 \ or \ -7[/tex]
Step-by-step explanation:
The given rational equation is presented here as follows;
[tex]\dfrac{x}{2 \cdot x + 14} + \dfrac{x - 4}{6} = \dfrac{3}{x^2} + 2\cdot x - 35[/tex]
A domain restriction are the limits to the ranges of input values (x-values) of a function
The three main types of domain restrictions are the reciprocal function, the log function, and the root function
The form of restriction in the given rational are reciprocal form, which are;
[tex]\dfrac{x}{2 \cdot x + 14}[/tex], and [tex]\dfrac{3}{x^2}[/tex], from which the function is undefined when;
2·x + 14 = 0, therefore when x = -7, or x² = 0, when x = 0
Therefore, the domain restrictions are that the function is defines for all x, except x = -7 and x = 0
The domain restrictions are x ≠ -7 and x ≠ 0.

If the distance from D to D' is 10 and the distance from A to D is 5, what is the scale factor?
Answers:
1) 3
2) 2
3) 1/2
4) 1/3
Answer:
2
Step-by-step explanation:
Because 10/5 is 2
The scale factor for the given distances will be 2. The correct option is 2.
To determine the scale factor, we need to compare the distances between corresponding points in two similar figures. In this case, the distances between points D and D' in one figure and points A and D in the other figure are provided.
The scale factor is determined by dividing the distance between corresponding points in the two figures. Therefore, the scale factor can be calculated by dividing the distance from D to D' (10) by the distance from A to D (5):
Scale factor = Distance from D to D' / Distance from A to D = 10 / 5 = 2
Therefore, the correct answer is option 2). The scale factor is 2.

Step-by-step explanation:
X, Y and Z are three points on a map. Y is 85km and on a bearing of 190° from X. Z is on a bearing of 140°, from Y. Z is due south of X. Calculate the distance between X and Z rounded to 1 DP
Answer:
The distance between X and Z is approximately 95.99 km
Step-by-step explanation:
Given, X, Y and Z are three points on a map. Y is 85km and on a bearing of 190° from X. Z is on a bearing of 140°, from Y. Z is due south of X.(For Diagram Please Find in Attachment)
Thus, The parameters areThe distance of Y from X = 85 km
The bearing of Y from X = 190°
The bearing of Z from Y = 140°
The bearing of Z from X = 180°
Now,
In triangle XYZ, we have∠YZX = 180° - (130° + 10°) = 40°
Therefore, Apply the sine rule here, we get
(85 km)/sin(40°) = XZ/(sin(130°))
XZ = sin(130°) × (85 km)/sin(30°) ≈ 95.99 km
The distance between X and Z ≈ 95.99 km
Write an expression in simplest form for the perimeter of a right triangle with leg lengths of 12a5 and 9a5.
Given:
The lengths of legs of a right triangle are [tex]12a^5[/tex] and [tex]9a^5[/tex].
To find:
The perimeter of a right triangle.
Solution:
In a right angle triangle,
[tex]Hypotenuse=\sqrt{Leg_1^2+Leg_2^2}[/tex]
[tex]Hypotenuse=\sqrt{(12a^5)^2+(9a^5)^2}[/tex]
[tex]Hypotenuse=\sqrt{144a^{10}+81a^{10}}[/tex]
[tex]Hypotenuse=\sqrt{225a^{10}}[/tex]
On further simplification, we get
[tex]Hypotenuse=\sqrt{(15a^{5})^2}[/tex]
[tex]Hypotenuse=15a^5[/tex]
Now, the perimeter of the triangle is the sum of all of its sides.
[tex]Perimeter=Leg_1+Leg_2+Hypotenuse[/tex]
[tex]Perimeter=12a^5+9a^5+15a^5[/tex]
[tex]Perimeter=36a^5[/tex]
Therefore, the perimeter of the right triangle is [tex]36a^5[/tex].
