evaluate the expression if a=-2 and b = 5

Evaluate The Expression If A=-2 And B = 5

Answers

Answer 1

If , a = (-2) and b = 5

Then :-

[tex] = \frac{8 \times 5 - 6 \times ( - 5)}{13} [/tex]

[tex] = \frac{40 - ( - 30)}{13} [/tex]

[tex] = \frac{70}{13} [/tex]

[tex] = 5.384615[/tex]

[tex]∴ \: \frac{8 \times 5 - 6 \times ( - 5)}{13} = 5.384615[/tex]

Answer:

6. The triangle is acute

m<P = 60

m<Q = 84

m<R = 36

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

7. Claim: the three angles added together equal 180 degrees

m<J = 116 degrees

m<K = 33 degrees

m<L = 38 degrees

Step-by-step explanation:

m<P = 4a + 12 = 4(12) + 12 = 60

m<Q = 7a = 7(12) = 84

m<R = 3a = 36

(4a + 12) + 7a + 3a = 180 degrees

14a + 12 = 180

14a = 168

a = 12

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

m<J = 4x + 12 = 4(26) + 12 = 116

m<K = x + 7 = 26 + 7 = 33

m<L = 2x - 14 = 2(26) - 14 = 38

(4x + 12) + (x + 7) + (2x - 14) = 180 degrees

7x - 2 = 180

7x = 182

x = 26

3 (2n + 4) - 2 = 1 +5 (n + 1)​

Answers

Answer:

n = -4

Step-by-step explanation:

Start off by remembering PEMDAS which first P means parenthesis so use distributive property to multiply the 2n + 4 by the 3 in front of it and do the same to the n + 1 and multiply that by the 5 in front which turns your question into 6n+12-2=1+5n+5 so now i'd combine like terms on both sides which now gives you 6n + 10 = 5n +6 so now to get the n on one side i'm going to sub tact it from both sides doesnt matter which one you do but to make it easier i'd subtract the 5n from the 6n because the whole point is to solve for n and by doing that you'd already be getting it by itself. so now the question should look like n + 10 = 6 so subtract 10 from both sides to isolate the n and you get your answer n = -4

Answer:

N = - 4

Step-by-step explanation:

3 (2n+4)-2=1+5(n+1

distribute 3 through the paretheses

6n+12-2=1+5n

add the numbers

6n+10=6+5n

move constant to the right-hand side and change its sign

6n-5n=6-10

calculate the difference

n = - 4

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

The graph of the linear function shown in the image.

Now,

Two points on the graph are (3, 350) and (2, 250).

Hence, Rate of change = (250 - 350) / (2 - 3)

                                    = -100/-1

                                    = 100

Thus, The rate of change with respect to the number of deposit will be 100.

Sarah, Lacey, and Mark stuffed envelopes with invitations for parents to an open house.

• Sarah stuffed 10 more envelopes than Lacey.

• Mark stuffed 3 less than twice as many envelopes as Lacey.

• Altogether they stuffed 503 envelopes.

If x represents the number of envelopes that Lacey stuffed, which equation BEST represents this situation?

x+10+2x−3=503

x+10x+3−2x=503

x+x+10+2x−3=503

x+x+10+3−2x=503

Answers

Answer: x+x+10+2x−3=503

Step-by-step explanation:

Let's define 3 variables:

S = # of stuffed envelopes by Sarah.

X = # of stuffed envelopes by Lacey.

M = # of stuffed envelopes by Mark.

S = 10 + X.

M = 2*X - 3.

X + S + M = 503.

Now we can replace the first two equations into the third equation:

X + (10 + X) + (2*X - 3) = 503.

Then the correct option is: x+x+10+2x−3=503

Now we can also solve the equation, just because it is fun:

X + 10 + X + 2*X - 3 = 503

4*X + 7 = 503

4*X = 503 - 7 = 496

X = 496/4 = 124

Lacey stuffed 124 envelopes.

Solve |6x+ 72| = 12 x Identify the solution and an extraneous solution.​

Answers

solution x=12

extraneous solution x=-4

The solution of the absolute value equation is x = 12, and the extraneous solution is x = -4

How to solve the absolute value equation?

Here we have the equation:

|6x + 72| = 12*x

Then we can rewrite this in two ways as:

6x + 72 = -12*x

6x + 72 = 12x

We can find two solutions for x. For the first one:

6x + 12x + 72 = 0

18x = -72

x = -72/18 = -4

For the other equation we get:

6x - 12x + 72 = 0

6x = 72

x = 72/6 = 12

Which is the extraneous solution?

It is x = -4, because we will get:

|6*-4 + 72| = 12*-4

48 = -48
