Step-by-step explanation:

E is before 2 and after 3 so it's the only answer for 2.4

B is -1 $\frac{4}{5}$ because it's - $\frac{1}{5}$ away from -2

D is 0.6 because it's right after 1 and

C is -0.2 because it's right after 0

A is -2 $\frac{3}{5}$ because it's before -3 but after -2

2.4=E

-1 4/5= B

-0.2= c

-2 3/5= A

0.6= D

The vertices of parallelogram ABCD are A(2,1),B(3,4),C(5,3), and D(4,0). ABCD is reflected over the x-axis to create parallelogr

Scorpion4ik [409]

So, coordinates of QRST will be:

Q(2,−1),R(3,−4),S(5,−3),T(4,0)

Option D is correct.

Step-by-step explanation:

The vertices of given parallelogram ABCD are A(2,1),B(3,4),C(5,3), and D(4,0).

ABCD is reflected over the x-axis to create parallelogram QRST

We need to find coordinates of QRST.

When the graph is reflected across x-axis, the x-coordinate remains the same, while y-coordinate becomes opposite i.e the sign is changed of the given coordinate.

So, coordinates of QRST will be:

Q(2,−1),R(3,−4),S(5,−3),T(4,0)

All the y-coordinates have been converted to their opposite signs

So, Option D is correct.

Is the point (-2, 5) a solution to the equation 2x + 5y = 0?

ratelena [41]

Answer:

Step-by-step explanation:

substitute -2 for 'x' and 5 for 'y'

2(-2) + 5(5) = 0?

-4 + 25 = 21, not 0

Convert from Standard Form to Slope Intercept Form 3x + 2y = 6

Ilia_Sergeevich [38]

Answer:

y = -3/2x + 3

General Formulas and Concepts:

Algebra I

Equality Properties

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define

Standard Form: 3x + 2y = 6

Step 2: Find slope-intercept form

Subtract 3x on both sides: 2y = 6 - 3x
Divide both sides by 2: y = 3 - 3/2x
Rewrite: y = -3/2x + 3

And we have our final answer!

The height of a cable that runs between two supports on a suspension bridge can be modeled by a quadratic function () where is t

Murrr4er [49]

What is the vertex

Its vertex is at (36, -10)

Let us assume that the left edge of the cable is at the origin.

Since the cable is at its lowest height 10 feet halfway between the two supports, the y-coordinate of its lowest point is -10 ft and the x coordinate is 72 ft/2 = 36 ft.

So, its vertex is at (36, -10)

Axis of symmetry

The y-axis.

Since the cable is symmetric about its lowest point, the axis of symmetry is the y-axis.

Domain

The domain is (0, 72).

Since the minimum value of its x-coordinate is at the origin which is x = 0 and the maximum value is at the other support which is at x = 72 ft,

the domain is (0, 72).

Range

The range is (0, -10)

Since the minimum value of the y-coordinate is -10ft and the maximum value is at the origin y = 0,

the range is (0, -10)

x and y-intercepts

The x-intercept is (0, 72) and the y-intercept is (0, 0)

Since the cable is attached at the origin and at 72 feet away from the origin at the other support, the x-intercept is 0 and 72 ft and the y-intercepts are 0 and 0.

So, the x-intercept is (0, 72) and the y-intercept is (0, 0)

How do you know if AB and CD are congruent?

Mariana [72]

If the length of two segments is equal then the two segments are congruent.

If l(AB) = l(CD) then seg AB ≅ seg CD.

Two line segments to be congruent if and only if they have the same length.

Two shapes are congruent if they are exactly the same shape and exactly the same size. In congruent shapes, all corresponding sides will be the same length and all corresponding angle will be the same measure.
