Step-by-step explanation:
How do you solve this equation: 80x =
11100
Divide by 11100 on both sides
Multiply by 80 on both sides
Multiply by 11100 on both sides
Divide by 80 on both sides
Answer:
Divide by 80 on both sides
What is the y-intercept of y=5x-2
Answer:
the y intercept is -2
Step-by-step explanation:
the y intercept is always the value on the end
Answer slope-intercept form is y = mx+ b y = m x + b, where m m is the slope and b b is the y-intercept. y = mx +b y = m x + b Find the values of m m and b b using the form y = mx+b y = m x + b.

Simplify using the division rule
14,252
Trs
Answer:
2rs
Step-by-step explanation:
simplify- 2*7r^2s^2/7rs
r^2 divided by r^1=r^(2-1)=r^1=r
s^2 divided by s^1=s^(2-1)=s^1=s
canceling out 7 as it appears on both sides of the fraction line
Prove that √sec²
Given:
Consider the given statement is
[tex]\sqrt{\sec^2\theta+\text{cosec}^2\theta}=\tan \theta+\cot \theta[/tex]
To prove:
The given statement.
Solution:
We have,
[tex]\sqrt{\sec^2\theta+\text{cosec}^2\theta}=\tan \theta+\cot \theta[/tex]
Taking LHS, we get
[tex]LHS=\sqrt{\sec^2\theta+\text{cosec}^2\theta}[/tex]
[tex]LHS=\sqrt{\dfrac{1}{\cos^2\theta}+\dfrac{1}{\sin^2\theta}}[/tex]
[tex]LHS=\sqrt{\dfrac{\sin^2\theta+\cos^2\theta}{\sin^2\theta\cos^2\theta}}[/tex]
[tex]LHS=\sqrt{\dfrac{1}{\sin^2\theta\cos^2\theta}}[/tex] [tex][\because \sin^2\theta+\cos^2\theta=1][/tex]
[tex]LHS=\dfrac{1}{\sin\theta\cos\theta}[/tex]
[tex]LHS=\dfrac{\sin^2\theta+\cos^2\theta}{\sin\theta\cos\theta}[/tex] [tex][\because \sin^2\theta+\cos^2\theta=1][/tex]
[tex]LHS=\dfrac{\sin^2\theta}{\sin\theta\cos\theta}+\dfrac{\cos^2\theta}{\sin\theta\cos\theta}[/tex]
[tex]LHS=\dfrac{\sin\theta}{\cos\theta}+\dfrac{\cos\theta}{\sin\theta}[/tex]
[tex]LHS=\tan \theta+\cot \theta[/tex]
[tex]LHS=RHS[/tex]
Hence proved.

7(3.5)=24.5
y = x^2 + 8x + 15 find the y-intercept
Answer:
15
Step-by-step explanation:
To find the y-intercept, just set the x value to 0:
[tex]y=0^2+0x+15=15[/tex]
Find the zeros of the function.
Enter the solutions from least to greatest.
g(x) = -10x2 + 490
lesser =
greater x =
Answer:
Lesser = -490
Greater x = 100x
Step-by-step explanation:
The zeros is basically the opposite numbers to make the equation equal to 0.
We have -10x^2(I believe it's a power)
and we have + 490
so,
-10x^2 = -100x
So the opposites to make those is:
+ 100x because, -100x + 100x = 0
and -490 because, 490 - 490 = 0.

Tiles with the letters A, B, C, D, E, F, G, and H written on them are placed in a bag. Malik draws out one letter at random. Which statements about the situation are true? Check all that apply.
The number of possible outcomes is 8.
The probability of drawing the tile with E written on it is 1/4
P(vowel) = 1/4
P(vowel) + P(consonant) does not = 1
Choosing one letter at random is a simple event.
Answer:
P(vowel) = [tex]\frac{1}{4}[/tex]
Choosing one letter at random is a simple event.
Step-by-step explanation:
P(vowel) = [tex]\frac{1}{4}[/tex]
This is because there are 2 vowels so the probability [tex]\frac{2}{8}[/tex] is which can be simplified to [tex]\frac{1}{4}[/tex] .
Moreover, Choosing one letter at random is a simple event.
The definition of a simple event is one that can only happen in one way, or in other words, it has a single outcome.
Malik's probability of drawing one letter at random is 1/4.
Probability calculation:P (vowel) = [tex]\bold{ \frac{1}{4}}[/tex] It's good to select one letter at random. P(vowel) = [tex]\bold{ \frac{1}{4}}[/tex]Since there are two vowels, the probability is [tex]\bold{ \frac{2}{8}}[/tex], is equal [tex]\bold{ \frac{1}{4}}[/tex].Furthermore, picking one letter at random is an easy procedure.A simple event is one that can only happen one way or has just one conclusion.Find out more about the probability here:

market stall holder bought a variety of coloured 'hoodies to sell. Each hoodie costs the stall holder $20 and she intends to sell them to the public at a mark up of 65%
write the percentage mark up value as:
1) fraction in simplest form
2) decimal
Answer:
20 x 0.65 = 13
20 + 13 = 33
20 x 65/100 = 13

What are the solutions to (3x - 2) (4x + 1) = 0?
9514 1404 393
Answer:
x = 2/3, -1/4
Step-by-step explanation:
The zero product rule tells you a product will be zero only if one or more factors is zero. The solutions to this equation are the values of x that make one or the other of the factors be zero.
3x -2 = 0
3x = 2
x = 2/3 . . . . makes the first factor zero
__
4x +1 = 0
4x = -1
x = -1/4 . . . . makes the second factor zero
__
The solutions are ...
x = 2/3 or x = -1/4

2 (x + 3 )= -x
Answer:
-2 =x
Step-by-step explanation:
2 (x + 3 )= -x
Distribute the 2
2x+6 = -x
Subtract 2x from each side
2x+6-2x = -x-2x
6 = -3x
Divide each side by -3
6/-3 = -3x/-3
-2 =x
Answer:
x = -2
Step-by-step explanation:
2 (x + 3) = -x
2x + 6 = -x
- 6 -6
2x = -x - 6
+x + x
3x = -6

OH OKK NICE TELLING ME
Step-by-step explanation:
-2(v - 2) = -3 – 2v
Answer:
no solution
Step-by-step explanation:
Given
- 2(v - 2) = - 3 - 2v ← distribute left side
- 2v + 4 = - 3 - 2v ( subtract 4 from both sides )
- 2v = - 7 - 2v ( add 2v to both sides )
0 = - 7 ← not possible
This indicates the equation has no solution
Two sides of a triangle measure 20 cm and 30 cm. Which of the following could be measure of the third side.
A-3cm
B-6cm
C-11cm
Answer:
11 cm
Step-by-step explanation:
the other two choices are too short
If 30 is the hypotenuse, the other two sides must exceed 30.
Answer:
C-11cm
Step-by-step explanation:
The sum of two sides of a triangle must always be bigger than the third!
3+20 is less than 30
6+20 is less than 30
11+20 is greater than 30!
