Answer:
x=2.5 for the second question!
x= -8.3 repeating for the 5th question
Step-by-step explanation:
Answer:
1. x = 9
2. x = 5/2
3. x = -64
4. x = -20
5. x = -5
6. x = 19
7. x = -6
Step-by-step explanation:
1.
-3x + 9 = -18
-3x = -27
x = 9
2.
2x - 14 = -9
2x = 5
x = 5/2
3.
x/2 + 8 = -24
x/2 = -32
x = -64
4.
-2.5x - 10 = 40
-2.5x = 50
x = -20
5.
-6x - 10 = 20
-6x = 30
x = -5
6.
50 = 2x + 12
38 = 2x
19 = x
x = 19
7.
x/2 - 7 = -10
x/2 = -3
x = -6

a pair of parametric equations to model the path of the beetle. Which point represents the location of the beetle 5
seconds after starting?
Answer:
It actually (70, 195)
Step-by-step explanation:
The point that represents the location of the beetle 5 seconds after starting are; (70, 195).
How to define Parametric Equations?The pair of parametric equations to model the path of the beetle is;
x(t)= 14t and y(t)= 37t + 10
An animation shows a beetle crawling in a straight line from the point (0, 10) to the point (28, 84) in 2 seconds.
Proving the answer;
At t(0,10), x = 0 and y = 10
Thus;
For X-coordinate;
x(0) = 14(0)
x(0) = 0
Similarly;
For y-coordinate;
y(0) = 37(0) + 10
y(0) = 10
That corresponds with the coordinate t(0, 10).
At t = 2 seconds, we have;
For x-coordinate;
x(2) = 14(2)
x(2) = 28
Similalry, for the y-coordinate;
y(2) = 37(2) + 10
y(2) = 160
Now, At t = 2 seconds, we have;
For x-coordinate;
x(5) = 14(5)
x(5) = 70
Similalry, for the y-coordinate;
y(5) = 37(5) + 10
y(5) = 195
The point that represents the location of the beetle 5 seconds after starting are; (70, 195).

Answer:
[tex]\boxed {\boxed {\sf 53}}[/tex]
Step-by-step explanation:
This is a right triangle, which we know because of the little square in the corner.
We can use the Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
where a and b are the legs and c is the hypotenuse.
In this triangle, 28 and 45 are the legs, because they make up the right angle. The unknown side is the hypotenuse, because it is opposite the right angle.
[tex]a=28 \\b=45 \\[/tex]
[tex](28)^2+(45)^2=c^2[/tex]
Solve the exponents.
(28)²= 28*28= 784[tex]784+(45)^2=c^2[/tex]
(45)²=45*45=2025[tex]784+2025=c^2[/tex]
Add the two numbers.
[tex]2809=c^2[/tex]
Solve for c by isolating it on one side of the equation. c is being squared. The Inverse of a square is the square root. Take the square root of both sides of the equation.
[tex]\sqrt{2809} =\sqrt{c^2}[/tex]
[tex]\sqrt{2809} = c[/tex]
[tex]53=c[/tex]
The third side and hypotenuse of the triangle is 53
[tex]\pink{\sf Third \: side \: of \: the \: triangle = 53}[/tex]
Solution :As, the given triangle is a right angled triangle,
Hence, We can use the Pythagoras' Theorem,
[tex]\star\:{\boxed{\sf{\pink {H^{2} = B^{2} + P^{2}}}}}[/tex]
Here,
H = Hypotenuse of triangleB = Base of triangle P = Perpendicular of triangleIn given triangle,
Base = 45 Perpendicular = 28 Hypotenuse = ?Now, by Pythagoras' theorem,
[tex]\star\:{\boxed{\sf{\pink {H^{2} = B^{2} + P^{2}}}}}[/tex]
[tex] \sf : \implies H^{2} = (45)^{2} + (28)^{2}[/tex]
[tex] \sf : \implies H^{2} = 45 \times 45 + 28 \times 28[/tex]
[tex] \sf : \implies H^{2} = 2025 + 784[/tex]
[tex] \sf : \implies H^{2} = 2809[/tex]
By squaring both sides :
[tex] \sf \sqrt{H^{2}} = \sqrt{2809}[/tex]
[tex] \sf : \implies H^{2} = \sqrt{2809}[/tex]
[tex] \sf : \implies H^{2} = \sqrt{(53)^{2}}[/tex]
[tex] \sf : \implies H^{2} = 53 [/tex]
[tex]\pink{\sf \therefore \: Third \: side \: of \: the \: triangle \: is \: 53}[/tex]

Identify an equation in point-slope form for the line perpendicular to
y=1/4x-7 that passes through (-2,-6).
A. y+6= -4(x+2)
B. y+6= -1/4(x+2)
C. y+2 = -4(x+ 6)
D. y-6=1/4(x-2)
Given:
Equation of line is [tex]y=\dfrac{1}{4}x-7[/tex].
The perpendicular line passes through (-2,-6).
To find:
The point slope form of perpendicular line.
Solution:
We have,
[tex]y=\dfrac{1}{4}x-7[/tex]
On comparing this equation with [tex]y=mx+b[/tex], we get
[tex]m=\dfrac{1}{4}[/tex]
Slope of given line is [tex]\dfrac{1}{4}[/tex].
Product of slopes of two perpendicular of the lines is -1.
So, [tex]Slope\times \dfrac{1}{4}=-1[/tex]
[tex]Slope=-4[/tex]
Slope of required line is -4 and it passes through (-2,-6). So, the point slope form is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope.
[tex]y-(-6)=-4(x-(-2))[/tex]
[tex]y+6=-4(x+2)[/tex]
Therefore, the correct option is A.
if the second term of a geometric series is 48 and its fifth term is 6 then find the sum of its first term 6 terms
Answer:
The answer is 189.
Step-by-step explanation:
This geometric sequence is actually just a division of 2 for every term downwards. Therefore, we can see the first term is [tex]48 \cdot 2[/tex] which is 96. Hence, we can work our way down from there:
List:
First term: 96
Second term: 48
Third term: 24
Fourth term: 12
Fifth term: 6
Sixth term: 3
Now, all we have to do is to add all the first 6 terms together to get:
[tex]96 + 48 + 24 + 12 + 6 + 3[/tex]
[tex]= 189[/tex]
The answer is 189.

can somebody please help
Answer and Step-by-step explanation:
1. 3(5x - 4) = 8x + 2
15x - 12 = 8x + 2
15x - 8x = 2 + 12
7x = 14
x = 2
2. 9(n + 3) = 7n - 3
9n + 27 = 7n - 3
9n – 7n = -3 – 27
2n = – 30
n = –15
3. 2(10 - 6x) = x - 8x
20 - 12x = -7x
20 = -7x + 12x
20 = 5x
x = 4
4. 5a + 4(3a - 8) = 4 + 13a
5a + 12a - 32 = 4 + 13a
17a - 32 = 4 + 13a
17a - 13a = 4 + 32
4a = 36
a = 9
5. 2y + 18 = 12 - 6(y + 7)
2y + 18 = 12 - 6y - 42
2y + 6y = 12 - 42 - 18
8y = -48
y = -6
6. x - (5 - 3x) = 7x + 4
x - 5 + 3x = 7x + 4
4x - 7x= 4 + 5
-3x = 9
x = -3
7. 8(m - 5) = 2(3m - 8)
8m - 40 = 6m - 16
8m - 6m = -16 + 40
2m = 24
m = 12
8. -4(3 - 6d) = 9(2d - 2)
-12 + 24d = 18d - 18
24d - 18d = -18 + 12
6d = -6
d = -1
9. 7(10 - 3w) = 5(15 - 4w)
70 - 21w = 75 - 20w
-21w + 20w = 75 - 70
-w = 5
w = -5
10. 6t + 3(5t - 4) = 12(2t - 5)
6t + 15t - 12 = 24t - 60
21t - 24t = -60 + 12
- 3t = -48
t = 16
11. 2(9x - 1) = 99 - 7(3 - 4x)
18x - 2 = 99 - 21 + 28x
18x - 28x = 99 - 21+2
-10x = 80
x = -8
12. 6(5k - 8) - 20 = 11(2k - 3) + 3k
30k - 48 - 20 = 22k - 33 + 3k
30k - 68 = 25k - 33
30 - 25k = -33 + 68
5k = 35
k = 7
13. - x - (13 + 4x) = -3(5 - 9x) + 2
-x -13 - 4x = -15 + 27x + 2
-5x - 13 = -13 + 27x
-13 + 13 = 27x + 5x
0 = 32x
x = 0
This is a complex fraction
12 - 4 + 6 / 4 - 2 + 3

Pentagon PENTA has coordinates P(0,0), E (4,4), N (8,4), T ( 8,-4), and A (4,-4) and is dilated at the origin with a scale factor of 3/4. Select all that are coordinates of P’E’N’T’A?
Answer:
5
Step-by-step explanation:
because thats the answer
Answer:
P'(0,0), E' (3,3), N'(6,3), T'(6,-3), A'(3,-3)
Step-by-step explanation:
1.The dilation is by a scale factor of 3/4 meaning it's less than one, meaning the image will get smaller.
2.To find the new coordinates, multiply 3/4 by each number in the coordinate pair. For example 4x3/4 is 3 making (4,4) (3,3).

Dawn is y years old.
Rashid is three times as old as Dawn.
Hugo is seven years younger than Dawn.
The total of Dawn's age, Rashid's age and Hugo's age is T years.
a) Find a formula for T in terms of y.
Answer:
T= y+ 3y-7
Step-by-step explanation
I'm pretty sure you can also write T= 4y-7 as a simplified form of the equation
The formula for T in terms of y can be written as;
T= y+ 3y -7
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
Given that Dawn is y years old.
So, Rashid is three times as old as Dawn means R = 3y
Hugo is seven years younger than Dawn means H = y - 7
The total of Dawn's age, Rashid's age and Hugo's age is T years.
We can also write T= 4y-7 as a simplified form of the equation

Answer:
hi
Step-by-step explanation:
im adding an answer so u can giveee the guy brailiestz
Answer:
376.8 m²
Step-by-step explanation:
The formula for finding the surface area of a cylinder is SA=2πr²+2πrh, where r is the radius of the base and h is the height of the cylinder. Using the diameter of the base, we can first calculate that the radius of the base is 10/2=5 meters. Then, we can plug our values into the equation.
SA=2πr²+2πrh
SA=2π(5)²+2π(5)(7)
SA=2π(25)+2π(35)
SA=50π+70π
SA=120π
Because the question asks us to use 3.14 for π, we plug that into our equation.
SA=120(3.14)
SA=376.8 m²
