Solve for y and x<br> 2+3x-1=4y <br> And <br> 2x-3=y
Natasha_Volkova [10]

Answer:

x = 2.6, y = 2.2

Step-by-step explanation:

if 4y = 2 + 3x - 1 and

y = 2x - 3,

4y = 2 + 3x -1 and 4y = 8x - 12 so

8x - 12 = 2 + 3x - 1

so 5x - 12 = 1,

5x = 13,

x = 2.6

If x = 2.6,

y = 5.6 - 3

so y = 2.2

6. A line passes through (1, -5) and (-3, 7).
Phantasy [73]

Answer:

1.y−7=3(x+3)

2.y=3x+16

Step-by-step explanation:

use point-slope formula to find the slope and plug it into the equation

y-y₁=m(x-x₁)

slope= -\frac{y2-y1}{x2-x1}

plug in the value of x and y from both  of the coordinates into this equation and then use one set of points and slope to get your equation

Is a trinomial always a higher degree than a monomial explain why or why not
KatRina [158]

Answer:  NO

<u>Step-by-step explanation:</u>

Let's define some of the vocabulary words so we can understand what is being asked.

trinomial: 3 terms   → each term is separated by a plus or minus sign

                               Example: 5x² + 3x + 2

monomial: 1 term   →  no plus or minus sign exists in the term.

                               Example: 5x²

degree: the largest exponent → it can be in any of the terms.

                               Example: 5x² has a degree of 2

It is possible that a monomial has an exponent greater than that of a trinomial so the answer is NO!

trinomial:   5x² + 3x + 2      has a degree of 2

monomial: 5x⁴                    has a degree of 4

TRIANGLE CONGRUENCE! PICTURE ADDED. How is QTP congruent to SPT?
shtirl [24]

Answer:

The triangles are congruent because:

  1. QP = ST
  2. angle P = angle T
  3. the side PT is in both triangles

We know when 2 sides of two triangles and the angle between them is congruent, the triangles are congruent.
