Answer:

-2; 4

Step-by-step explanation:

6x - 8y + 1 = 6(1/2) - 8(3/4) + 1 = 3 - 6 + 1 = -2

3xy - 2x² = 3*4*3 - 2*4² = 36 - 32 = 4

Use the substitution method

Answers:

6x-8y+1

6(1/2)-8(3/4)+1

Cross out 6 and 2 , divide by 2. 6/2= 3 , 2/2= 1, 3/1= 3

Cross out 8 and 4 divide by 4 . -8/4= -2 , 4/4= 1, -2/1= -2 and -2*3= -6

3-6+1

3-5

= -2

3xy-2x^ 2

3(4)(3)-2(4)^ 2

(3)(4)(3)= 36

write out 4 and 4 ( two times because of the exponent)

4*4= 16

36-2(16)

Mutiply first then subtract

-2*16= -32

36-32

= 4

Which are linear pairs? Check all that apply. ∠DAE and ∠EAD ∠BAC and ∠CAD ∠BAE and ∠EAD ∠EAD and ∠DAC ∠CAE and ∠BAD

mariarad [96]

Answer:

B). ∠BAC and ∠CAD

C). ∠BAE and ∠EAD

D). ∠EAD and ∠DAC

Step-by-step explanation:

As we know, a linear pair consisting of angles at a single point of the line has a sum of 180° in total. In other words, two supplementary angles together comprise a linear pair. In the given figure, the pair of supplementary angles ∠BAC and ∠CAD, ∠BAE and ∠EAD, and ∠EAD and ∠DAC are the linear pairs as their sum is 180°. Thus, options B, C, and D are the correct answers.

point b, o, and y are collinear on by, and bo:oy = 5/8. B is located at (4,2,) o is located at (57/8,-3) and Y is located at (x,

Lena [83]

Given: BO : OY = 5:8. Coordinate B is located at (4,2,) ; O is located at (57/8,-3) and Y is located at (x,y).

We have to determine the coordinate Y.

We will use cross section formula which states:

The coordinates $(x_1,y_1) , (x_2,y_2)$ are divided in the ratio $m_1 : m_2$ by the Coordinate A. So, the coordinates of A are given by the formula:
