<h3>I'll teach you how to solve 4m^2 - 10= -6</h3>

-----------------------------------------------------

Add 10 to both sides:

4m^2-10+10= -6+10

Simplify:

4m^2= 4

Divide both sides by 4:

4m^2/4= 4/4

Simplify:

m^2= 1

For x^2 = f(a) the solutions are x =  \sqrt f(a) - \sqrt f(a):

m= \sqrt 1, m= -\sqrt 1

Simplify:

m = 1, m = -1

Your Answer Is m = 1, m = -1

plz mark me as brainliest :)

Answer:m = 3,-2, as

4m - 2 = 10                                 and                             4m - 2 = -10

4m = 12                                      and                              4m = -8

m = 3                                          and                              m = -2

Evaluate the following expression if a=-9, b=-7,c=9 and d=3<br> 2cd + 3ab =
stepladder [879]

Answer:

<h3>The answer is 243.</h3>

Step-by-step explanation:

To evaluate the expression substitute the values of a , b , c and d into the above expression

a = - 9

b = - 7

c = 9

d = 3

So we have

2cd + 3ab = 2(9)(3) + 3(-9)(-7)

= 2(27) + 3( 63)

= 54 + 189

We have the final answer as

<h3>243</h3>

Hope this helps you

Given: Lines a and b are parallel and line c is a transversal. Prove: Angle2 is supplementary to Angle8 Horizontal and parallel
kondaur [170]

Answer:

The correct option is;

Corresponding angles theorem

Step-by-step explanation:

Type of lines of lines a and b = Horizontal and parallel lines

The transversal to a and b = Line c

The angles between a and c labelled clockwise from the upper left quarter segment =  1, 2, 4 and 3

The angles between b and c labelled clockwise from the upper left segment =  5, 6, 8 and 7

Therefore, we have;

Statement   {}                                                   Reason

1. a║b, c is a transversal   {}                             Given

2. ∠6 ≅ ∠2       {}                                              Corresponding angles theorem

3. m∠6 = m∠2       {}                                         Definition of congruent

4. ∠6 is supp. to ∠8        {}                               Definition of linear pair

5. ∠2 is supp. to ∠8        {}                               Congruent supplement theorem

Corresponding angles are the angles located in spatially similar or matching corners of two lines that have been crossed by the same transversal. When the two lines having a common transversal are parallel, the corresponding angles will be congruent.

−1.2(3x − 3) = 4(3x +0.9)<br><br><br> help pls
Viefleur [7K]

Answer:

- 1.2(3x - 3) = 4(3x + 0.9) \\  - 3.6x + 3.6 = 12x + 3.6 \\  12x + 3.6x = 3.6 - 3.6 \\ 15.6x = 0 \\  \\ x =  \frac{0}{15.6}  \\  \\ x = 0

I hope I helped you^_^
