Answer:

y = 2x + 1

Step-by-step explanation:

1. Find the slope: change in y/change in x

[tex]\frac{5-1}{2-0}[/tex] = 2

Slope: 2

2. Find y-intercept by substituting in a point (0, 1)

y = 2x + b

1 = b

3. Put the equation together

y = 2x + 1

The equation of the line passing through the points (0, 1) and (2, 5) is y = 2x + 1.

y intercept is the y coordinate of the point on the line where it touches the Y axis. The x coordinate will be 0 there.

The equation of a line in slope intercept form is,

y = mx + c

Here m is the value of the slope and c is y intercept.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Given two points (0, 1) and (2, 5).

Slope, m = (5 - 1) / (2 - 0)

               = 4 / 2

               = 2

c is the y coordinate when x = 0.

We have that point given (0, 1).

So c = 1

Substituting m = 2 and c = 1 in the general form, we get,

y = 2x + 1

Hence the equation of the line is y = 2x + 1.

No

Step-by-step explanation:

since the magnitude of xy ≠ zw,

|x-y| = xy = |52-121|= 69, |z-w| = zw = |-21-25| = 46

69 ≠ 46

7 is prime so the least common denominator is 7 times 2 times 5 which is 70.

Answer:

48 sq inches

Step-by-step explanation:

Given that,

Ribbon used around a bulletin broard is 28 inches

The length of her board is 6 inches

Let B is breadth of her board. 28 inches is perimeter. The perimeter of rectangle is given by :

P = 2(L+B)

28=2(6+B)

14=6+B

B=8 inches

The area of a rectangle is given by :

A = L×B

A = 8×6

A=48 sq inches

So, the area of her board is 48 sq inches

When saying something like [tex]E_{23}[/tex] we are looking at the item in the second row and third column of matrix E.

The acronym DNE stands for "Does Not Exist". It's another way of saying "Undefined". For instance, note how matrix E has only 3 columns. When we write [tex]E_{34}[/tex] we're asking about something in the fourth column, but no such column exists.

Answer:

Iris weighs 55 pounds, Ivan weighs 65 pounds.

Step-by-step explanation:

Divide 120 by 2: 60

Then make the 10 pound difference by adding and subtracting 5 to 60 for each answer: 55 and 65.

Iris = 55 pounds

Ivan = 65 pounds

Let x be Iris and y be Ivan.

x+ y = 120

y-10+ y = 120

2y - 10 = 120

2y = 120 + 10

2y = 130

y = 130/2

y = 65 pounds

x = y-10

= 65-10

x = 55 pounds

Step-by-step explanation:

Answer:

Step-by-step explanation:

From the picture attached,

From ΔABC,

m∠B = 180° - (m∠C + m∠A)

        = 180° - (90° + 32°)

        = 180° - 122°

        = 38°

Now we have to find the trigonometric ratio of BC and AB from ΔABC,

Since, sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

sin(32°) = [tex]\frac{BC}{AB}[/tex]

[tex]\frac{BC}{AB}=0.53[/tex]

Therefore, ratio of BC and AB represents the "sine of angle A".

Answer:32.4

Step-by-step explanation:

The measure of ∠W to the nearest 10th of a degree is, 32.9°.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know, The cosine rule of triangles, In a triangle, ABC with sides opposite to A is a and similar for b and c.

We have. cosA = (b² + c² - a²)/2bc.

Therefore, m∠W = (u² + v² - w²)/2uv.

m∠W = 0.84.

So, cosФ = 0.84.

Ф = cos⁻¹(0.84).

Ф = 32.9°.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Range of the function is the set of y-values (output values) of the function on the graph.

Domain of the function is the set of x-values (input values) of the function.

Domain of the function : [-5, 4)

(including x = -5 and excluding x = 4)

Range : [-4, 2)

(Including y = -4 and excluding y = 2)

x - intercepts : x = -5, -2, 2

Average rate of change over the interval [0, 2]

= [tex]\frac{f(2)-f(0)}{2-0}[/tex]

= [tex]\frac{0-(-4)}{2-0}[/tex] [Since, f(2) = 0, f(0) = -4]

= 2

Right most interval where the graph is positive → [2, 4]

The key feature of a function include the intercepts and intervals of the function

(a) The range

The least y value on the graph is at y = -4, and the maximum is at y = 2, with an open circle.

So, the range is:

[tex]\mathbf{Range = [-4,2)}[/tex]

(b) The domain

The least x value on the graph is at x = -5, and the maximum is at x = 4, with an open circle.

So, the domain is:

[tex]\mathbf{Domain = [-5,4)}[/tex]

(c) The x-intercepts

This is the point where the graph crosses the x-axis.

So, we have:

[tex]\mathbf{x-intercept =-2 \ and\ 2}[/tex]

(d) Average rate of change over [0,2]

From the graph, we have:

f(0) = -4

f(2) = 0

So, the average rate of change (m) is:

[tex]\mathbf{m = \frac{f(2) - f(0)}{2 - 0}}[/tex]

[tex]\mathbf{m = \frac{0 - -4}{2 - 0}}[/tex]

[tex]\mathbf{m = \frac{4}{2}}[/tex]

[tex]\mathbf{m =2}[/tex]

(d) The right-most interval where the graph is positive

The graph is positive from x = 2 to x = 4.

Hence, the right-most interval where the graph is positive is [2,4]
