Answer:

(0,3)

Step-by-step explanation:

It is where the lines intersect

The value of the g(x) is equal to the value of f(x). Then the solution of the equation is at (0, -3).

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

The given expression are as follows

g(x) = -2x - 3 and f(x) = Ix+1I - 4

For the solution of the system, the value of the g(x) is equal to the value of f(x). Then we have

[tex]\begin{aligned} \rm g(x) &= \rm f(x)\\\\\rm -2x - 3 &= \rm x + 1 - 4\\\\-\rm 2x - 3 &= \rm x - 3\\\\\rm 3x &= 0\\\\\rm x &= 0 \end{aligned}[/tex]

Then the g(x) will be

g(x) = -2(0) - 3

g(x) = - 3

Then the solution of the equation is at (0, -3).

Answer:

Number of red marbles = 13

Number of green marbles = 12

Number of blue marbles = 5

Total Number of marbles = 13+12+5

Total Number of Marbles = 30 marbles

[tex] \bf \: probability \: of \: blue \: marbles \: = \frac{number \: of \: blue \: marbles}{total \: number \: of \: marbles} [/tex]

[tex]\sf \dashrightarrow \: probability \: of \: blue \: marble = \frac{5}{30} \\ \\ \sf \dashrightarrow \: probability \: of \: blue \: marble = \cancel \frac{5}{30} \\ \\ \sf \dashrightarrow \: probability \: of \: blue \: marble = \frac{1}{6} [/tex]

So, the probability of blue marbles would be ⅙ .

Answer:

1/6 chance of getting blue

Step-by-step explanation:

find your total (30) that will be your denominator

the number of blue marbles will be your numerator (5)

then simplify 5/30 to 1/6

Answer:

Two angles are congruent if they have the same measure. If you didn't already know, when two lines intersect the vertical angles formed are congruent. For example, all the angles in a square are congruent. All the angles in a regular pentagon are 108°, therefore all the angles are congruent because they are the same.

Step-by-step explanation: Hope this helps:).........if not sorry:(

Answer:

Well, AN angle (as you've stated in your question) can't, by definition, be congruent; you need at least two angles. Once that condition is met, then we can say that two angles are congruent if they have the same measure.

Zoe:

P = $5,500

r = 0.085

A = 2P

Aubrey:

P = $5,500

r = 0.0825

Step 2: Find Time

Find time elapsed by using Zoe.

So the time it takes for Zoe to get double her money is approximately 8.15467 years.

Step 3: Find Audrey's Money

∴ after the elapsed time of approximately 8.15467 years, Zoe would have made double her money valued at $11,000 and Audrey would have made $10,498.10.

Answer:

Green nails

Step-by-step explanation:

Solution:

Note that:

Simplify the equation to find x.

→ x + 108 + (180 - 133) = 180°

→ x + 108 + (47) = 180°

→ x + 155 = 180°

→ x = 180 - 155 = 25°

Answer:

x = -11/9

Step-by-step explanation:

3(x-4) + 1 = 12x

Step 1: Use distributive property

3*x - 3*4 + 1 = 12x

3x - 12 + 1 = 12x

Step 2: Combine like terms

3x - 11 = 12x

Step 3: Subtract '3x' from both sides

-11 = 12x - 3x

-11 = 9x

Step 4: Divide both sides by 9

-11/9 = x

Answer:

Solve the first part in Parenthese

Step-by-step explanation:

3(X-4)

3x-12+1=12x

         -1   -1

3x-11-12=12x

        -12 -12

3x-11=0x

    -11  -11

3x= -11x

The image point for the given rule and preimage is (6 - 8)

When we apply a rule T<a, b> to a preimage point (x, y) we get the image (x + a, y + b), so this is like a translation.

So if we apply the rule T<4, -1> to the preimage point (2, -7), the image will be:

(2 + 4, - 7 + (-1)) = (6 - 8)

Concluding, the image point is (6 - 8)

The limits are important in calculus and mathematical analysis and can be used to define integrals, derivatives and continuity. The limit of the given function is 4.

In mathematics, the limit is defined as the value that a function approaches the output for the given input values. It is used in the analysis process and it always concerns about the behaviour of the function at a particular point.

The upper and lower limits are used to define the definite integrals whereas the indefinite integrals are defined without using the limits and it have an arbitrary constant while integrating the function.

The limit of the given function is:

limₓ → -1  (2x² + 3x + 5)

(2 × (-1)² + 3 × (-1) + 5)

(2 × 1 + (-3) + 5) = ( 2 - 3 + 5)

= 4

So the limit of the given function is 4.

Answer:

If he scored x points in the first half, then x + p = 31

Answer:

expression:

first half points + second half points = total points obtained

Let first half points be y

y + p = 31

y = 31 - p ......this is the expression.

solve:

y = 31 - p

y = 31 - 7

y = 24 points
