Math help!!! What’s the answer to 1&2?

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.

solution x=12

extraneous solution x=-4

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

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

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

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

48 = -48

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.

Answer:

∠FJH ≅ ∠BJA

Step-by-step explanation:

From the image we can see that the only congruent relation ∠FJH has is with ∠BJA which is due to these angles being vertically opposite

So, ∠FJH and ∠BJA are vertically opposite and hence, congruent. We can say that ∠FJH ≅ ∠BJA

Very hard work u know

Answer:

If [tex]k > 0[/tex], then [tex]x[/tex] must be greater than 0.

Step-by-step explanation:

If [tex]k > 0[/tex], then we state that [tex]e^{5\cdot x} > 0[/tex] and [tex]e^{5\cdot x}[/tex] is a trascendental function with a lower bound so that [tex]e^{5\cdot x}> 1[/tex]. Then, the minimum value of [tex]k[/tex] is 1 and we proceed to solve the latter equation to find the value of [tex]x[/tex]:

[tex]e^{5\cdot x}> 1[/tex]

[tex]\ln e^{5\cdot x} > \ln 1[/tex]

[tex]5\cdot x > 0[/tex]

[tex]x > 0[/tex]

Therefore, [tex]x[/tex] must be greater than 0.

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
