My friend Dubble got 10 rews and corazs for about $32. Rews for $2 each and some corazs for $8 each

Answers

Answer:

"Dubble" bought 10 rews for $2.00 each and 1 corazs for $8.00 each

-I put quotation marks on Dubble bc i didnt know if it was a boy or girl name sorryyy its.. um.. unique :)          -

Step-by-step explanation:

The price for the rews is 10x 2 because the price of each is $2 and he got 10 so he spent $20 on rews.

Then you subtract the total amount of money "Dubble" used buying these things and the amount of money "Dubble" used on the rews which is 32-20=8

The last step is that you divide 8 by the pice of each corazs which is 8 divided by 8 so the answer is 1.

Hope this helped you sorry im a little late bubs.<3

How would i know if a line on a graph has passed the vertical line test?

Answers

Answer:

The vertical line will only pass the graph line once.

Step-by-step explanation:

For example, I found an example online. The vertical line intersects a circle twice. But on a horizontal squiggly line, it only touches it once. So the circle is NOT a function but the squiggly line IS a function.

Hope this helps!! Brainiest is appreciated!! Happy Holidays!!!!


To use the vertical line test, take a ruler or other straight edge and draw a line parallel to the y-axis for any chosen value of x. If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function.

Ellis is making some beef burgers for his friends. His recipe 500g of beef mince and 120g of cheese to make four burgers. He buys 1.5 of mince and 400g of cheese, and makes as many burgers as possible. How much cheese will he have left over

Answers

Given :

Ellis is making some beef burgers for his friends.

His recipe 500g of beef mince and 120g of cheese to make four burgers.

He buys 1.5 of mince and 400g of cheese, and makes as many burgers as possible.

To Find :

How much cheese will he have left over.

Solution :

500 g and 120 g of beef mince and cheese respectively make 4 burgers.

125 g and 30 g of beef mince and cheese respectively make 1 burgers.

Now, we will keep increasing  the ingredients until there is any shortage of any ingredients.

1000 g and 240 g will make 8 burgers.

1500 g and 360 g will make 12 burgers.

1625 g and 390 g will make 13 burgers.

Cheese left is ( 400 - 390 ) g = 10 g.

Therefore, 10 grams of cheese will be left.

What are the roots of the equation x2 + 15x = -57 in simplest a + bi form?

Answers

Answer:

Step-by-step explanation:

Rewrite x2 + 15x = -57 as x^2 + 15x + 57 = 0, in which the coefficients of this quadratic are {1, 15, 57}.

Then the discriminant is b^2 - 4ac  =  225 - 4(1)(57) = -3

                                     

Because the discriminant is negative, we know that the two roots will be complex.  They are:

      -15 ±i√3

x = ---------------

Answer:

Step-by-step explanation:

We can add (15/2)² to complete the square:

  x² +15x +(15/2)² = -57 +(15/2)²

  (x +7.5)² = -0.75

  x +7.5 = ±i(√3)/2 . . . . take the square root

The roots are ...

A. -10
B. -18/125
C. 10
D. 18/125

Answers

D, because you multiply -6 with -3 which is 18, then multiple 5 and 25 which faces you 125.

The fraction represents the solution to (-6/5)/(-3/25) in the simplest form will be 10. Then the correct option is C.

What is Algebra?

Algebra is the study of algebraic expressions, while logic is the manipulation of those concepts.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to answer the problem correctly and precisely.

The fraction numbers are given below.

-6/5 and -3/25

Then the division of the numbers -6/5 and -3/25 will be given by putting a division sign between them. Then we have

⇒ (-6/5) ÷ (-3/25)

⇒ (-6/5) / (-3/25)

⇒ (6/5) x (25 / 3)

⇒ 150 / 15

⇒ 10

The part that addresses the answer for (- 6/5)/(- 3/25) in the most straightforward structure will be 10. Then the right choice is C.

How many solutions does the following equation have?
3x + 7 + 2x = 5x + 7
One. Many. None

Answers

Answer:

Infinite/many

Step-by-step explanation:

3x + 7 + 2x = 5x + 7

3x + 2x + 7 = 5x + 7

5x + 7 = 5x + 7

5x - 5x + 7 = 7

7 = 7

Infinite solutions

Answer: many (all real numbers)

Step-by-step explanation:

1) add 2x and 3x to give you 5x

You now have 5x+7=5x+7

2) you can simplify this by subtracting 7 on both sides and dividing by 5

3) you are then left with x=x

Write an equation in slope-intercepts form for the line that passes through (5, -4) and is perpendicular to the line described by 2x-10y=0
EXPLAIN what you did in each step to arrive at your answer plz

Answers

Answer:

y = -5x + 21

Step-by-step explanation:

First, put 2x - 10y = 0 into slope intercept form to find the slope:

Subtract 2x from both sides:

-10y = -2x

Divide each side by -10:

-10y = -2x

y = 1/5x

So, the slope of the line is 1/5.

Perpendicular lines have opposite reciprocal slopes, so the slope of the other line will be -5.

Then, use the equation y = mx + b to plug in the slope and the point given.

Solve for b:

y = mx + b

-4 = -5(5) + b

-4 = -25 + b

21 = b

Lastly, plug in the slope and b into y = mx + b to create the equation in slope intercept form:

y = -5x + 21 is the equation
