solve for y -20x - 4y = 16
Answer:
y = -5x - 4
Step-by-step explanation:
-20x - 4y = 16
-4y = 20x + 16
4y = -20x - 16
y = -5x - 4
In the figure below, DF is a straight line. What is the degree measure of <FEG?
Answer:
c. 56 degrees
Step-by-step explanation:
angle FEG and angle DEG add up to 180.
2x-6+3x-31=180
x=31
2(31)-6=56
The measure of angle ∠ FEG is,
∠ FEG = 56°
We have to given that,
Angles are defined as,
∠ FEG = (2x - 6)°
∠ DEG = (3x + 31)°
Here, Angles FEG and angle DEG are linear pair.
Hence, angle FEG and angle DEG add up to 180.
2x - 6 + 3x + 31 = 180
5x + 25 = 180
5x = 180 - 25
5x = 155
x = 155 / 5
x = 31
Therefore, The measure of angle ∠ FEG is,
∠ FEG = (2x - 6)°
∠ FEG = (2 × 31 - 6)°
∠ FEG = (62 - 6)°
∠ FEG = 56°

The growth of a certain organism can be modeled by C(t)=10(1.029)^24t, where C(t) is the total number of cells after t hours. Which function is approximately equivalent to C(t)?
1. C(t) =240(0.083)^24t
2. C(t)=10(.083)^t
3. C(t)=10(1.986)^t
4. C(t)= 240(1.986)^t/24
Given:
The function is:
[tex]C(t)=10(1.029)^{24t}[/tex]
Where, C(t) is the total number of cells after t hours.
To find:
The function that is approximately equivalent to C(t).
Solution:
We have,
[tex]C(t)=10(1.029)^{24t}[/tex]
It can be rewritten as:
[tex]C(t)=10(1.029^{24})^{t}[/tex] [tex][\because (a^m)^n=a^{mn}][/tex]
[tex]C(t)\approx 10(1.986)^{t}[/tex] [tex][\because 1.029^{24}\approx 1.986][/tex]
The function [tex]C(t)=10(1.986)^{t}[/tex] is approximately equivalent to C(t).
Therefore, the correct option is 3.

X =
Exterior Angle =
3x + 25°
20°
X + 550
Answer:
x=65°
Step-by-step explanation:
Since all exterior angles add up to 360°.
⇒(3x+25°) + (20°) + (x+55°) =360°
⇒4x+100°=360° {Add up like terms}
⇒4x=260° {Subtract 100 from both sides}
∴ x=65° {Isolate x (divide both sides by 4)}

solve the linear equations elimination -2x+3y= 7 5x+8y= -2
Answer:
x=-2, y= 1
Step-by-step explanation:
Given data
-2x+3y= 7 --------------1
5x+8y= -2--------------2
Multiply 1 by 5 and 2 by 2 and add
-2x+3y= 7 X 5
5x+8y= -2 X 2
-10x+15y= 35
10x+16y= -4
0x+31y= 31
31y= 31
y= 31/31
y= 1
put y= 1 in eqn 1
-2x+3y= 7
-2x+3(1)= 7
-2x+3=7
-2x= 7-3
-2x= 4

A B and C from a triangle where BAC =90 AB = 7.4 mm and CA = 12 and find the length of AC , giving your answer rouned to 1DP
Question: A B and C form a triangle where BAC = 90°. AB = 7.4 mm and CA = 12 mm. Find the length of BC, giving your answer rounded to 1 DP.
Answer:
14.1 mm
Step-by-step explanation:
From the diagram attached,
Using pythagoras theorem,
a² = b²+c²............... Equation 1
From the attached file,
Given: a = x, b = 7.4 mm, c = 12 mm
Substitute these values into equation 1, and solve for x
x² = 7.4²+12²
x² = 54.76+144
x² = 198.76
x = √(198.76)
x = 14.1 mm
Hence, the length of BC = 14.1 mm
In each equation, select an operation to make the equation true. 24 ____34=18 24 ____−34= - 32 12 ____ -15 = -3 12 ____ -15 = 27 -18 ____ −34= 24
Answer:
1) 24 - 40 + 34 = 18
2) 24 - 22 - 34 = -32
3) 12 + 0 -15 = -3
4) 12 + 30 -15 = 27
5) -18 + 76 -34 = 24
Step-by-step explanation:
The given equations are;
1) 24 _ 34 = 18
We have;
18 - (34 + 24) = -40
Therefore;
24 - 40 + 34 = 18
2) 24 _ - 34 = -32
We have;
-32 - (24 - 34) = -22
Therefore;
24 - 22 - 34 = -32
3) 12 _ -15 = -3
We have;
-3 - (12 - 15) = 0
Therefore;
12 + 0 -15 = -3
12 - 15 = -3
4) 12 _ -15 = 27
We have;
27 - (12 - 15) = 30
Therefore;
12 + 30 -15 = 27
5) -18 _ -34 = 24
We have;
24 - (-18 - 34) = 76
Therefore;
-18 + 76 -34 = 24.
1. 24 x 34=18
2. 24 ➗ -34=-32 (i dont have the division thing lol)
3. 12 - 15=-3
4. 12 - (-15)=27
5. -18 x -34=24

If you have a 30 degree reference angle, the side opposite (the side not part of the reference angle) is 1/2 the size of the hypotenuse.
Since the side opposite is 12, the hypotenuse is easily found.
1/2 = opposite / hypotenuse
1/2 = 12 / hypotenuse Cross multiply
hypotenuse = 2 * 12
hypotenuse = 24
Now use the Pythagorean Theorem to get the third side.
c = 24
a = 12
b = ?
a^2 + b^2 = c^2
12^2 + b^2 = 24^2
144 + b^2 = 576 Subtract 144 from both sides.
b^2 = 576 - 144
b^2 = 432
Now you have to factor 432 down to its primes
432 = 2 * 2 * 2 * 2 * 3 * 3 * 3
The rule is for every two 2s you take one outside the root sign and throw the other one away. If there are an odd number of factors, leave one of them under the root sign.
sqrt(b^2) = sqrt(432)
b = 4 * 3sqrt(sqrt(3))
b = 12 sqrt(3)
Answer
r = 12*sqrt(3)
t = 24
The answer is D

Given the sequence 9,6,3,0,..., at what nth term will the number become -24?
Answer:
12
Step-by-step explanation:
A sequence is given and we need to find the term when it will become -24 . The given sequence is,
9 , 6 , 3 ,0 , . . . . .
Here Common Difference can be calculated by subtracting consecutive terms . So the Common Difference is 6-9 = -3 . Here the nth term is (-24) .Now using the formula to find nth term .
⇒ T_n = a + (n-1)d
⇒ (-24) = 9 + (n-1)(-3)
⇒ -24-9 = (n-1)(-3)
⇒ (n-1) = -33/-3
⇒ n-1 = 11
⇒ n = 11 + 1
⇒ n = 12
Hence the required number of term is 12.What is the area of the triangle?

which is the solution to 4/5(n-3)=n-2
Answer:
-2 = n
Step-by-step explanation:
Multiplying both sides by (5/4) quickly isolates (n - 3):
(5/4)(4/5)(n - 3) = (5/4)(n - 2), or
n - 3 = (5/4)(n - 2)
Let's eliminate fractions by multiplying both sides by 4:
4n - 12 = 5n - 10
Combining like terms, we get -2 = n

50 POINTS if p=(-2,-1) and Q=(-6,-3) are the endpoints of the diameter of a circle, find the equation of the circle
Answer:
(x+4)^2 + (y+2)^2 = 5
Explanation:
Using the midpoint formula, we find that the center of the circle is (-4, -2). We also calculate using the distance formula that between the two points is [tex]\sqrt{2\\0}[/tex]or [tex]2\sqrt{5\\\\}[/tex].
Because we found the diameter, to find the radius we divide by two, getting [tex]\sqrt{5\\\\}[/tex].
Now that we have the center, (-4, -2), and the distance from the center to the radius, we can put the information into the circle equation:
(x-h)^2 + (y-k)^2 = r^2
This becomes:
(x+4)^2 + (y+2)^2 = 5
Answer:
-4 , -2 , 5Step-by-step explanation:
(x-(-4))^2+(y-(-2))^2=5
since 2 negatives equal a positive, - -4 = +4
same thing for -2
(x+4)^2+(y+2)^2=5
Solve for y: 5(y + 2/5) = -13
Answer:
y = -3
Step-by-step explanation:
Let's solve your equation step-by-step.
5 (y+2/5) = −13
Step 1: Simplify both sides of the equation.
5(y+2/5)= −13
(5)(y) + (5)(2/5) = −13(Distribute)
5y + 2 = −13
Step 2: Subtract 2 from both sides.
5y + 2 − 2 = −13 −2
5y = −15
Step 3: Divide both sides by 5.
5y/5 = −15/5
y = −3
Answer:
y = −3
