A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.

What is the equation of a line?

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The graphs can be described as shown below.

A.) The first graph has the y-intercept at 2. Therefore, the first graph can be described by the equation, y =5x + 2.

B.) For the second graph, the graph passes through the point (-1,0). Therefore, if we substitute the value of y as 0 in the equation y=3x+3, we will get x=-1.

Hence, the equation of the second graph is y=3x+3.

C.) For the third graph, the graph passes through the point (-1.5,0). Therefore, if we substitute the value of y as 0 in the equation y=2x+3, we will get x=-1.5.

Hence, the equation of the second graph is y=2x+3.

Answers

Minimizing the sum of the squared deviations around the line is called Least square estimation.

It is given that the sum of squares is around the line.

Least squares estimations minimize the sum of squared deviations around the estimated regression function. It is between observed data, on the one hand, and their expected values on the other. This is called least squares estimation because it gives the least value for the sum of squared errors. Finding the best estimates of the coefficients is often called “fitting” the model to the data, or sometimes “learning” or “training” the model.

find the value of p in the given figure

Answers

The value of p is 60°

How to determine the value

The figure given is a triangle and it is important to note that sum of angles in a triangle = 180 degrees

The other sides are gotten by;

Angle on a straight line = 180

110 + x = 180

x = 180 - 110

x = 70

The other interior angle

130 + y = 180

y = 180 - 130

y = 50

We have,

x + y + p = 180

70 + 50 + p = 180

120 + p = 180

p = 180 -120

p = 60°

Thus, the value of p is 60°

Is this right or wrong

Answers

Answer:

∠C and ∠F are right angles

Step-by-step explanation:

To prove that two triangles are congruent using HL, one must have:

a right angle congruent,a leg congruent, and the hypotenuse (the side across from the right angle) congruent.

For this problem, there are two sides of the triangle already congruent:  one could be the hypotenuse (if the right angle were across from it), and the other congruent side could be a leg.  So, if we can prove either that angles C & F are right angles, or that angles A & D are right angles, that would be enough to use HL congruence.

Hence, from the answer choices provided, proving that angle C and angle F are both right angles would be sufficient to prove the triangles are congruent via HL congruence.

Side note:  Proving angles B and E would not be enough to use HL congruence, because the hypotenuse is always across from the right angle.  So, if angle B were a right angle, it would mean that side AC was the hypotenuse (which hadn't yet been proven or stated to be congruent).

While not enough to prove triangle congruence via HL, if angle B and E were congruent at all (right angles or not), it would be enough to prove that the triangles were congruent by SAS (side-angle-side) because it would have proven that two sides and the included angle were congruent.

Ashley and Castel each improved their yards by planting daylilies and ornamental grass. They
bought their supplies from the same store. Ashley spent $118 on 2 daylilies and 14 bunches of
ornamental grass. Castel spent $98 on 14 daylilies and 7 bunches of ornamental grass. What is the
of one daylily and the cost of one bunch of ornamental grass? Also could you show work

Answers

Each daylily cost $3 and one bunch of ornamental grass cost $8.

Build two equation's: (Let 'd' be daylilies, 'o' be ornamental grass)

$118 on 2 daylilies and 14 bunches of ornamental grass.

2d + 14o = 118

$98 on 14 daylilies and 7 bunches of ornamental grass.

14d + 7o = 98

Make d subject for first equation.

2d + 14o = 118

2d = 118 - 14o

d = (118 - 14o)/2

d = 59 - 7o

Insert this into second equation.

14(59 - 7o) + 7o = 98

826 - 98o + 7o = 98

-91o = -728

o = 8

Find value of d:

d = 59 - 7o

d = 59 - 7(8)

d = 3

Answer:

Cost of one daylily = $3

Cost of one bunch of ornamental grass = $8

Step-by-step explanation:

Define the variables:

Let d = cost of one daylily (in dollars)Let g = cost of one bunch of ornamental grass (in dollars)

Given information:

$118 = 2 daylilies and 14 bunches of ornamental grass$98 = 14 daylilies and 7 bunches of ornamental grass

Create a system of equations with the given information and defined variables:

[tex]\begin{cases}2d+14g=118\\14d+7g=98 \end{cases}[/tex]

Multiply the second equation by 2:

[tex]\implies 2(14d+7g)=2(98)[/tex]

[tex]\implies 28d+14g=196[/tex]

Subtract the first equation from this equation to eliminate the variable g:

[tex]\begin{array}{r r r}28d & +14g = & 196\\- \quad \quad2d & +14g = & 118\\\cline{1-3}26d & = & 78\end{array}[/tex]

Solve for d:

[tex]\implies 26d=78[/tex]

[tex]\implies d=3[/tex]

Substitute the found value of d into one of the equations and solve for g:

[tex]\implies 2d+14g=118[/tex]

[tex]\implies 2(3)+14g=118[/tex]

[tex]\implies 6+14g=118[/tex]

[tex]\implies 14g=112[/tex]

Answers

Answer:

  C.  Ian rode less than 1 hour

Step-by-step explanation:

It never hurts to think about what the problem statement is telling you. Ian rode at a speed that would take him 18 miles in 1 hour.

Interpretation

Clearly, Ian would pass the 15-mile mark in a 1-hour ride before an hour had elapsed. If he only rode 15 miles, he rode less than 1 hour.

The actual time Ian rode is given by the relation between speed, time, and distance.

  time = distance/speed

  time = (15 mi)/(18 mi/h) = (15/18) h = 5/6 h

Ian's riding time was 5/6 of an hour, which is less than 1 hour.

Answer:

Answer:

B

Step-by-step explanation:

y = x² → (1)

y = 3x - 2 → (2)

substitute y = x² into (2)

x² = 3x - 2 ← subtract 3x - 2 from both sides

x² - 3x + 2 = 0 ← in standard form

(x - 1)(x - 2) = 0 ← in factored form

equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 2 = 0 ⇒ x = 2

substitute these values into (2) for corresponding values of y

x = 1 : y = 3(1) - 2 = 3 - 2 = 1 ⇒ (1, 1 )

From equation (2)

9x - 2y = 38

y = 4.5x - 19 -------- (3)

Substitute this into equation (1)

-7x + 18x - 76 = -32

-7x + 18x = -32 + 76

x = 4

Substitute the value of x into equation (3)
