Answer:

f(-2) = -1

Step-by-step explanation:

-2 is x, so replace x as -2 into the equation

f (-2) = 2(-2) + 3

f (-2) = -4 + 3

f (-2) = -1

A collection of all points in the plane of the form (x, f(x)) is the graph of a function f. The graph of f is defined as the graph of the equation y = f(x).

[tex]\to f (x) = 2x + 3[/tex]

[tex]\to f(-2) =?[/tex]

Putting the value "-2 " into the above given method:

⇒  f(-2) = 2(-2) + 3

⇒  f(-2) = -4 + 3

⇒  f(-2) = -1

Answer:

quadrant 2

Step-by-step explanation:

top right is 1, top left is 2, bottom left is 3, and bottom right is 4

Step-by-step explanation:

check it.. i have solved it for you.

Given:

The first equation of the system of equations is

[tex]5x+2y=-4[/tex]

To find:

The equation that gives a system with no solution.

Solution:

We have,

[tex]5x+2y=-4[/tex]

It can be written as

[tex]2y=-5x-4[/tex]

[tex]y=\dfrac{-5x-4}{2}[/tex]

[tex]y=-\dfrac{5}{2}x-2[/tex]

On comparing this equation with slope intercept form [tex]y=mx+b[/tex], we get

[tex]m=-\dfrac{5}{2},b=-2[/tex]

It means the slope of the line is [tex]-\dfrac{5}{2}[/tex] and the y-intercept is -2.

Slope of parallel lines are same but the y-intercepts are different.

From the given options, the slope of the line is [tex]-\dfrac{5}{2}[/tex] only in option D and the y-intercept is -3 which is different from -2.

The line [tex]y=-\dfrac{5}{2}x-3[/tex] is parallel to the given line and parallel lines have no solution. So, the second equation of the system of equations is [tex]y=-\dfrac{5}{2}x-3[/tex].

Therefore, the correct option is D.

Answer:

Step-by-step explanation:

6). Since, m∠JMN = 90° [Given]

    And m∠JMK + m∠NMK = m∠JMN

    m∠JMK = m∠JMN - m∠NMK

                  = 90° - 28°

                  = 62°

    From the other figure,

    m∠STR + m∠STP = 180° [Linear pair of angles]

    m∠STR = 180° - m∠STP

                  = 180° - 118°

                  = 62°

    Therefore, mJMK = m∠STR = 62°

    And m∠JMK ≅ m∠STR

8). Since, BF is the angle bisector of ∠AFC,

    ∠AFB ≅ ∠BFC [By angle bisector theorem]

    ∠CFD ≅ ∠BFC [Given]

    Therefore, ∠AFB ≅ ∠CFD [Transitive property of equality]

9). AG is the bisector of CD,

    Therefore, CE ≅ DE ------- (1)

    IJ is the bisector of CE,

    Therefore, CK ≅ KE ---------(2)

    BH is the bisector of ED,

    Therefore, EF ≅ FD -------(3)

    Since, CE ≅ DE [Given as (1)]

    (CK + KE) ≅ (EF + FD)

    2(KE) ≅ 2(EF) [Given in properties (2) and (3)]

     KE ≅ EF

Answer:

- The temperature is 8 degrees below 0

- A student's class average decreases by 8 points.

Answer:

The temp is 8 degrees below 0, a student's class average decreases by 8 points

Step-by-step explanation:

a puppy gaining 8 pounds is positive

the temp is 8 degrees below 0 which is negative

the elevation of a hot air balloon is 8 meters above the ground

A student's class average decreases by 8 points = negative

The value -8 is negative and it doesn't say you have to only select one answer

1/5x-5+-3=y

Step-by-step explanation:

Answer:

y=1/5x-2

Step-by-step explanation:

(y - y1) = m(x - x1)

y-(-3)=1/5(x-(-5))

y+3=1/5(x+5)

y+3=1/5x+1

y=1/5x+1-3

y=1/5x-2

Answer:

2.82

Step-by-step explanation:

The formula for the circumference of a circle is given as:

π × D

Where D represents the Diameter of the circle.

From the question:

The circumference of a circle is 8.88cm.

The Length of the Diameter is calculated as:

8.88cm = π × D

D = 8.88 cm/π

D = 2.8265917893 cm

Approximately to 2 decimal places = 2.83cm

Therefore, the length of the diameter = 2.83 cm

Answer:

[tex] PQ=4\sqrt{2} \:cm=5.66 \: cm[/tex]

Area of square PQRS[tex] = 32\: cm^2 [/tex]

Step-by-step explanation:

ABCD is a square. Points P, Q, R and S are the midpoints of sides AB, BC, CD and DA of square ABCD respectively.

Therefore,

BP = 1/2 * AB = 1/2 *8 = 4 cm

BQ = 1/2 * BC = 1/2 *8 = 4 cm

In [tex] \triangle PBQ, \: m\angle PBQ =90\degree [/tex]

Therefore, by Pythagoras theorem:

[tex] PQ=\sqrt{4^2 +4^2} [/tex]

[tex] PQ=\sqrt{2*4^2} [/tex]

[tex] PQ=4\sqrt{2} \:cm=5.66 \: cm[/tex]

Area of square PQRS[tex] =PQ^2 [/tex]

Area of square PQRS[tex] =(4\sqrt{2}) ^2 [/tex]

Area of square PQRS[tex] = 32\: cm^2 [/tex]

Answer:

C = 17 - R

Step-by-step explanation:

In this scenario, 17 cars would be the initial starting point. While C would be the final number of cars, meaning that our equation would have to equal C. If she rents R number of cars then this number is being subtracted from the initial number of cars because Charmaine would no longer have them in his/her possession. Therefore, it is being subtracted. Using this information we can create the following equation.

C = 17 - R
