What is the solution to the system of equations? Use the substitution method.y=3x-4
9x-3y=14

A. There is no solution
B. (12, 14)
C. (14, 12)
D. There an infinite number of solutions.

Answers

Answer 1
Answer: { y = 3 x - 4
  9x -3y = 14

Subsititute y = 3x-4 :

[ 9 x - 3 ( 3 x-14 )=14]

Refine:

9 x  - 3 ( 3 x - 4 ) = 14

- 2 = 0

is false , therefore the system of equations has no solution

Answer A

hope this helps!

The brackets for a shelf are in a shape of a triangle. Find the angles of the triangle if the measures of the angles are in the ratio x : 2x : 3x :

Answers

ok so remember that al angles add to 180
angles are x,2x,3x

add
x+2x+3x=6x
6x=180
divide 6
x=30

tmes 2
30*2=60

30*3=90

the angles are 30,60,90 degrees
so the angles are 30 60 and 90 degrees.

Help on geometry similar triangles #4

Answers

Because BE // DC you have that AE / AD = BE / DC ;
AD = AE + ED;
AD = 9;
3 / 9 = BE / 15;
BE = ( 3 * 15 ) / 9;
BE = 5.

Elsa knows that for every bushel of apples she sells she earns $9 and for every basket of pears she earns $11. She uses the expression 9a + 11p to keep track of her earnings. Part A: Identify the coefficients and variables in the expression. (3 points)

Part B: How many terms are in the expression, what are they, and how do you know? (4 points)

Part C: Which term in the expression shows the total earned from selling baskets of pears? (3 points)

I only need help with b and c ?

Answers

B.  There are two terms, 9a and 11p.

C.  11p shows the total earned from selling pears, because she earns $11 per basket of pears, and when p increases by 1, the whole term increases by 11.

A triangle has sides measuring 15 15 and 15sqrt2 what are the angle measures of the triangle

Answers

We observe that we are in the presence of a rectangular triangle.
 Therefore, we have:
 An angle of 90 degrees.
 An angle that is given by:
 sine (x) = (15 / (15 * root (2)))
 sine (x) = (1 / root (2))
 x = asine (1 / root (2))
 x = 45 degrees
 And an angle that is given by:
 180-90-45 = 45 degrees
 Answer:
 The angle measures of the triangle are:
 90-45-45 degrees

PLEASE HELP ASAPExplain how the number of chromosomes per cell is cut in half during meiosis, in which the
diploid parent cell produces haploid daughter cells.

Answers

During meiosis I, homologous chromosomes are pulled apart to produce two daughter cells. These daughter cells then divide again in meiosis II, only now it is the sister chromatids that are split apart. The ploidy of the daughter cells is less than the ploidy of the parent cells, thus resulting in diploid parent cells and haploid daughter cells.
