Explain whether the points (−3,8), (−2,3), (−1,−2), (0,−7), (1,−12), and (2,−17) represent the set of all the solutions for the equation y=−5x−7.

A.Yes, because all solutions in the set of solutions for y=−5x−7 need to have integer values for both x and y.

B.Yes, because all of the points that are listed are on the line y=−5x−7.

C.No, because the x-intercept is not provided in the list of points.

D.No, because the set of all solutions of y=−5x−7 is represented by the line of the equation

Answers

Answer 1

Answer:

D

Step-by-step explanation:

We simply put each of the points to test

For a point to be correct, if we substitute the x-coordinate value, we should get the value of the y-coordinate

So let’s proceed

(-3,8)

8 = -5(-3) - 7

8 = 15 -7

8 = 8

(-2,3)

3 = -5(-2) - 7

3 = 10 -7

3 = 3

(-1,-2)

-2 = -5(-1) - 7

-2 = 5-7

-2 = -2

(0,-7)

y = -5x -7

y = -5(0) - 7

y = 0-7 = -7

(1,-12)

y = -5(1) -7

-12 = -5 -7

-12 = -12

(2,-17)

-17 = -5(2) -7

-17 = -10-7

-17 = -17

We can see that all the listed points are on the given line

Although all these points lie on the line, we cannot say they represent the set of all solutions

The set of all solutions can simply be represented by the line of the equation

Find the speed of a dog running 135 meters (m) to the right in 16s.

Answers

Based on the calculations, the speed of the dog is equal to 8.44 m/s.

Given the following data:

Distance = 135 meters.Time = 16 seconds.

To calculate the speed of the dog:

What is speed?

Speed can be defined as the distance covered by an object or living organism per unit of time. Thus, speed can be measured as meter per seconds.

Mathematically, speed is given by this formula;

[tex]Speed = \frac{distance}{time}[/tex]

Substituting the given parameters into the formula, we have;

[tex]Speed = \frac{135}{16}[/tex]

Speed = 8.44 m/s.

Answers

Answer:

10 is the answer

Step-by-step explanation:

Let squares be x, triangles be y and circle be z

Now,

x³ = 27

so, x = 3

Now,

x * y * y * y = 24

or, 3 * y³ = 24

or, y³ = 24/3

so, y³ = 8

so, y = 2

Again,

x * y * z² = 96

or, 3 * 2 * z² = 96

or, 6z² = 96

or, z² = 96/6

so, z² = 16

so, z = 4

Now,

z + x*y = 4 + 3*2 = 4 + 6 = 10

it should be 55, 27 divided by 3 is 9, 24-9 is 15, 15 divided by 3 is 5, 96-9-5=82, 82 divided by 2 is 41 so 41+5+9=55

Answer:

Step-by-step explanation:

the domain is the interval or set of all valid values for x.

reflecting the graph over the x-axis simply means to multiply the original function by -1.

that does not change the domain in any case. it only changes the range (the interval or set of possible y values).

so, the domain is the same as for the original function : all real numbers.

Zoe says an equilateral triangle is always an acute triangle, but an acute triangle is never an equilateral triangle. Which statement explains whether Zoe is correct or not

Answers

Answer:

Zoe is correct!

Step-by-step explanation:

The definition of an acute triangle is that all three angles are less than 90 degrees. An equilateral triangle has the angles 60, 60, and 60. All three are less than 90 degrees, so this means that an equilateral triangle is always an acute triangle.

However, that doesn't necessarily mean that an acute triangle is always an equilateral triangle.

Answers

Given that that the lengths of the parts of the secant are, QO = 14 and QP = 9, we have that the tangent, NO = 17.9

How can the length of the tangent be found?

The given parameters are;

Length of side, QP = 9

Length of QO = 14

Required;

The length of;

[tex] \overline{no}[/tex]

From the tangent and secant formula, we have;

[tex] { \overline{no}}^{2} = { \overline{qo}} \times ( { \overline{qp} \: + { \overline{qo}}})[/tex]

Which gives;

NO^2 = 14 × (9 + 14) = 322

NO = √(322) = 17.9

The length of the side NO = 17.9

X-intercept = (-4, 0)
y-intercept = (0, -8)

Answers

Answer:

y=[tex]\frac{1}{2}[/tex]x-8

Step-by-step explanation:

To solve this, you have to use the formula [tex]\frac{x_{2} -x_{1} }{y_{2} -y_{1}}[/tex] to find the slope.

[tex]\frac{0+4}{-8-0}[/tex] = 4/-8 = -1/2

so the slope is -1/2

Now, you plug your values into the formula y=mx+b

m = slope = 1/2

b = y-intercept = -8

so the final formula is y=[tex]\frac{1}{2}[/tex]x-8

State if the two triangles are congruent. If they are, state how you know.

Answers

Answer:  ASA

Explanation:

The angles marked with a single arc are one pair of congruent angles forming one "A" of "ASA".

The other "A" is the angles marked with double arcs.

The "S" refers to the sides between those said angles. These sides overlap perfectly so we have a shared side, meaning they must be the same length (refer to the reflexive property).

This is why the triangles are congruent by the ASA (angle side angle) congruence theorem. One triangle is a reflected version of the other. The mirror line being that shared overlapping side. Congruent triangles are like twin identical copies.
