True or false To find 7% of a number, multiply the number by 0.7
Answer:
true and it also depends on what question it is
Step-by-step explanation:
because 7% = 0.07 when doing a mathematical question it will help you a lot if you turn 7% into a decimal 0.07 and it will be more easier than doing it as a percentage.

Write an equation of the line in slope-intercept form that contains
(-3, 13) and (6,-5)
Answer:
[tex]y = -2x +7[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (-3,13)[/tex]
[tex](x_2,y_2) = (6,-5)[/tex]
Required
Determine the equation in slope intercept form
First, we calculate the slope:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
The equation becomes:
[tex]m = \frac{-5 - 13}{6 - (-3)}[/tex]
[tex]m = \frac{-5 - 13}{6 +3}[/tex]
[tex]m = \frac{-18}{9}[/tex]
[tex]m = -2[/tex]
The equation is then calculated using:
[tex]y -y_1 = m(x - x_1)[/tex]
Substitute values for y1, m and x1
[tex]y - 13 = -2(x -(-3))[/tex]
[tex]y - 13 = -2(x +3)[/tex]
[tex]y - 13 = -2x -6[/tex]
Make y the subject
[tex]y = -2x - 6 + 13[/tex]
[tex]y = -2x +7[/tex]

Find the values of X and why in the following equation.
(x+yi)+(4+9i)=9-4i
Answer:
The values of x and y are x = 5 and y = -13 ⇒ B
Step-by-step explanation:
If the complex numbers are A = (a + bi) and B = (c + di), then
A + B = (a + c) + (b + d)i
(a + c) is the real part(b + d) is the imaginary partLet us solve the question
∵ (x + yi) + (4 + 9i) = 9 - 4i
→ Add the real parts and the imaginary parts on the left side
∵ x, 4 are the real parts, and y and 9 are the imaginary parts
∴ (x + 4) + (y + 9)i = 9 - 4i
→ Compare the two sides, and equate the like terms
∵ 9 is the real part and -4 is the imaginary part
∴ x + 4 = 9
→ Subtract 4 from both sides
∴ x + 4 - 4 = 9 - 4
∴ x = 5
∵ y + 9 = -4
→ Subtract 9 from both sides
∵ y + 9 - 9 = - 4 - 9
∴ y = -13
Answer:
x = 5 and y = -13

write in slope intercept form
Answer:
[tex]-\frac{3}{5}[/tex]
The slope is -3/5
Step-by-step explanation:
Answer:
y=3/5x-2
Step-by-step explanation:
Right now, this equation is in standard from or Ax^2 + Bx = C and you need to convert it to slope-intercept from which is y=mx+b where m is the slope and b is the y-intercept
Convertion
3x-5y=10 Subtract 3x from both sides
-5y=-3x+10 Divide all terms by -5
You get
y=3/5x-2

A bag contains 4 sour-apple candies and 3 watermelon candies. One piece of candy is chosen at random and returned to the bag. Then a second piece of candy is chosen at random What is the probability that both pieces of candy chosen will be sour -apple ?
Answer: [tex]\dfrac{16}{49}[/tex]
Step-by-step explanation:
Given: A bag contains 4 sour-apple candies and 3 watermelon candies.
Total candies = 4+3 = 7
If replacement of candy is done, then the probability of getting sour apple will be the same and independent each time .
Probability of selecting sour apple candy= [tex]\dfrac{\text{Number of sour apple candy}}{\text{Total}}[/tex]
[tex]=\dfrac47[/tex]
Now , the probability that both pieces of candy chosen will be sour -apple =[tex]\dfrac47\times\dfrac{4}{7}=\dfrac{16}{49}[/tex]
hence, required probability = [tex]\dfrac{16}{49}[/tex]

sarah lost her science book her school charges a lost book fee equal to 75% of the cost of the book sarah recieved a notice she owes the school $60 for the book how much did the school pay for the book
Answer: $80
Step-by-step explanation:
You have been told that Sarah ended up paying $60, and you were told before that the charge for a lost book was 75%.
Therefore
$60 = 75%
Now we have to find out what amount of money would be equivalent to 100%:
To do this, find out what amount of money would be equivalent to 25% first.
You can do this by dividing both values by 3.
60 / 3 = 20
75 / 3 = 25
So now $20 = 25%
Now find 100% (which is the original amount) multiply each value by 4 :
$80 = 100%
So the school payed $80 for the book.
hope this helps :)
