Given g(x)=-2x+2, solve for x when g(x)=8

Answers

Answer:

x=±3. Explanation: g(x)=2x2−10 g(x)=8. ie 2x2−10=8 2x2=18 x2=9 x=±3.

Step-by-step explanation:

x = -3
To solve this, first set -2x + 2 = 8

Now you want to try to get x alone on one side so subtract 2 on both sides
-2x = 6

Finally divide both sides by -2 to find out what x is equal to

x =-3

To check if this is the right answer, plug -3 in for x in the original equation and see if it comes out as 8

-2(-3) + 2 = 8
6 + 2 = 8
8 = 8

Both sides are equal so -3 is the solution

Evaluate the expression when a=4 and b=-3.
-a +4b

Answers

Answer:

-16

Step-by-step explanation:

-a +4b

By putting the value a = 4 and b = -3

= -(4) + 4 × (-3)

= -4 - 12

= -16 (Ans)

Sense we know the values of a and b all we need to do is fill them in the problem and solve it
So once you fill them in it would give you -4+(4•-3)
Then you would simplify the parentheses
-4+(-12)
After wards you would add these two numbers together and since they are negative it would appear for the number to be bigger even though it is getter quite smaller
So the answer to this expression would be
= -16

Vanessa tried to prove that triangle KLM is congruent to triangle MNK. What is the first error Vanessa made in her proof?

Answers

Answer:

B. Vanessa only established some of the necessary conditions for a congruence criterion.

Step-by-step explanation:

The diagram does support the claim that \overline{KL}\cong\overline{MN}  

KL

≅  

MN

start overline, K, L, end overline, \cong, start overline, M, N, end overline because they both have two tick marks.

Step 1 is correct.

Step 2

The diagram does support the claim that \overline{LM}\cong\overline{NK}  

LM

≅  

NK

start overline, L, M, end overline, \cong, start overline, N, K, end overline because they both have a single tick mark.

Step 2 is correct.

Step 3

In this step, Vanessa claims that \triangle KLM\cong \triangle MNK△KLM≅△MNKtriangle, K, L, M, \cong, triangle, M, N, K using the side-side-side criterion. But Vanessa only established two pairs of congruent corresponding sides. To use this criterion, we must establish three pairs of congruent sides.

Vanessa would be able to use this criterion if she first established that \overline{MK}\cong\overline{KM}  

MK

≅  

KM

start overline, M, K, end overline, \cong, start overline, K, M, end overline (this can be done with the reason that line segments are congruent to themselves).

The first error Vanessa made in her proof was option B.

Vanessa only established two pairs of congruent corresponding sides

What is congruency?

polygons are congruent if they may be identical in size and shape - that is, if their corresponding angles and sides are the same.

Congruent shapes are shapes that can be exactly equal. The corresponding facets are identical and the corresponding angles are equal.
