Answer:

109, Corresponding angles postulate

Step-by-step explanation:

Angle 2 and the angle that’s 71 degrees are supplementary.

Just subtract 180 - 71 = angle 2

For the second box…

Alternate exterior angles is wrong (means congruent)

Vertical angles is wrong (means congruent)

Same-side interior angles is wrong (angle that’s 71 degrees is clearly outside)

Corresponding angles is RIGHT (Supplementary and the angle that’s 71 degrees is outside, and angle 2 is inside, so it’s corresponding.)

Alternate interior angles is wrong (means congruent)

telo118 [61]

Answer:

The toll on a bridge is $1.00 \:for\: cars\: and\: $2.50 for trucks. In one hour, a tollbooth operator collects a total of $105 in tolls.

Equation :---

$\boxed{c + 2.5t = 105}$

Above equation represents the relationship between the number of cars, c, and the number of trucks, t, which could have passed by this tollbooth.

Help please I need 5 points total. i need 2 to left of vertex. i need vertex. i need 2 to right of vertex. Please, quickly, I am

We are given with a quadratic equation which represents a Parabola , we need to find the vertex of the parabola , But let's recall that , For any quadratic equation of the form ax² + bx + c = 0 , the vertex of the parabola is given by ;

${\quad \qquad \boxed{\bf{Vertex = \left(\dfrac{-b}{2a},\dfrac{-D}{4a}\right)}}}$

Where , D = b² - 4ac (Discriminant)

Now , On comparing the given equation with ax² + bx + c , we have

⇢⇢⇢ a = 1 , b = - 10 , c = 27

Now , Calculating D ;

${:\implies \quad \sf D=(-10)^{2}-4\times 1\times 27}$

${:\implies \quad \sf D=100-108}$

${:\implies \quad \bf \therefore \quad D=-8}$

Now , Calculating the vertex ;

${:\implies \quad \sf Vertex =\bigg\{\dfrac{-(-10)}{2\times 1},\dfrac{-(-8)}{4\times 1}\bigg\}}$

${:\implies \quad \sf Vertex = \left(\dfrac{10}{2},\dfrac{8}{2}\right)}$

${:\implies \quad \bf \therefore \quad Vertex = (5,2)}$

Hence , The vertex of the parabola is at (5,2)

Note :- As the Discriminant < 0 . So , the equation will have imaginary roots .

Refer to the attachment for the graph as well .

If f = {(4, 2), (6, 1), (8, 4), (10, 2), (12, 5)}, what is the range

UNO [17]

Answer:

Range = {2,1,4,5}

Step-by-step explanation:

When a function is given in the form if a relation. i.e. ordered pairs.

When the function is given in the form of ordered pairs then the set of first elements i.e. x-coordinates of all ordered pairs forms domain while the set of second elements i.e. y-coordinate of all ordered pair is called range.

So in the given function:

Range = {2,1,4,5}

The repeating values are only written once..
