The correct y-intercept, slope, and equation for the line include the following:

Mathematically, the slope of any straight line can be calculated by using this formula;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Note: Each interval on this graph represents 1 unit.

By critically observing the graph, we can reasonably and logically deduce the following points through which the line passes through:

Points (x, y) = (0, 4)

Points (x, y) = (10, 0)

Substituting the given parameters into the formula, we have;

Slope, m = (0 - 4)/(10 - 0)

Slope, m = -4/10

Slope, m = -2/5.

At point (0, 4), a linear equation for the line can be calculated by using the slope-intercept form:

y = mx + c

Where:

Substituting the given parameters into the formula, we have;

y = mx + c

y = -2x/5 + 4

Answer:

x = 1

Step-by-step explanation:

- [tex]\frac{5}{2}[/tex] x + [tex]\frac{3}{4}[/tex] x = - [tex]\frac{7}{4}[/tex]

multiply through by 4 ( the LCM of 2 and 4 ) to clear the fractions

- 10x + 3x = - 7

- 7x = - 7 ( divide both sides by - 7 )

x = 1

Answer:

[tex]x=1[/tex]

Step-by-step explanation:

Given equation is:

[tex]-\frac{5}{2}x+\frac{3}{4}x=-\frac{7}{4}[/tex]

Simplifying the left side of the equation.

[tex]\frac{2(-5x)+3x}{4}=-\frac{7}{4}[/tex]

This is equivalent to:

[tex]\frac{-10x+3x}{4}=-\frac{7}{4}[/tex]

This gives:

Answer:

d = 2 and terms are 6, 8, 10 12 and 14

Step-by-step explanation:

we know

[tex] a_{n} = a_{1} + (n-1)d [/tex]

here a(n) = nth term

a1 = 1st term

n = no. of term

d = common difference

putting the values we get,

178 = 6 + (87-1)d

⇒ 178 = 6 + 86d

⇒86d = 172

⇒ d = 2

So required common difference is 2.

Now the first term is 2

so second term is a2 = 6 + ((2-1)×2) = 8

third term = 6 + ((3-1)×2) = 10

fourth term = 6 + ((4-1)×2) = 12

fifth term = 6 + ((5-1)×2) = 14

The difference between a positive mixed number and negative mixed number is never positive is false.

Answer:

62feet

Step-by-step explanation:

10x=620

x=62feet

The perimeter usually gives the length of the figure. In a square, which has al its sides equal, the perimeter of the square will be four times its sides. The maximum width of the rectangle is 62 feet.

The perimeter of a rectangle is defined as the total distance covered by its boundaries or the sides. Since the rectangle is comprised of four sides, the perimeter will be the sum of all four sides. The perimeter is a linear measure and its unit is m, cm, feet, etc.

The equation used to calculate the perimeter of a rectangle is given as:

Perimeter = 2 (l + b)

Here l = length

b = breadth

Here the length is four times the width, l = 4x

Width may be b = x

Then perimeter is:

P = 2 (4x + x) = 620

10x = 620

x = 620 / 10 = 62 feet

Thus the width is 62 feet.

The equations that are true include the following:

(8 × 7)/2 - 12 = 22 - (2 × 3)

48 ÷ 8 + 2³ = 5 + 3²

In order to determine the equations that have a true and valid solution, we would simplify and evaluate each of the equations as follows:

(8 × 7)/2 - 12 = 22 - (2 × 3)

Opening the bracket on both sides of the equation, we have:

56/2 - 12 = 22 - 6

28 - 12 = 16

16 = 16 (True).

48 ÷ 8 + 2³ = 5 + 3²

Evaluating the exponents, we have:

48 ÷ 8 + 8 = 5 + 9

6 + 8 = 14

14 = 14 (True).

150/5² = 30 - 4² - 12

Evaluating the exponents, we have:

150/25 = 30 - 16 - 12

Answer:

35%

Step-by-step explanation:

35 divided by 100 = 0.35 = 35%

Step-by-step explanation:

A quadratic equation is in the form of

[tex]ax {}^{2} + bx + c[/tex]

C is the y intercept a.k.a the value of c is when x=0,

when x is 0, c is -7 so

c=-7

[tex] {ax}^{2} + bx - 7 [/tex]

Next we know when x is 2, y is 1 so

[tex]a(2) {}^{2} + 2b - 7 = 1[/tex]

[tex]4a + 2b = 8[/tex]

When x is 5, y is -2

[tex]a(5) {}^{2} + b(5) - 7 = - 2[/tex]

[tex]25a + 5b = 5[/tex]

So we have a system of equations, using elimination.

[tex]5a + b = 1[/tex]

[tex] - 6a = 6[/tex]

[tex]a = - 1[/tex]

So

[tex]5( - 1) + b = 1[/tex]

The probability of a Poisson distribution is represented as

P(x) = λˣe⁻λ/x!

In this case,

x = At least 2

This means that

x = 2, 3....

So, we have

P(x ≥ 2) = 1 - P(0) - P(1)

This gives

P(x ≥ 2) = 1 - 3⁰ * e⁻³/0! - 3¹ * e⁻³/1!

The percentage of $0.95 to $3.80: 25%

What is Percentage?

A percentage, often known as percent, is a division by 100. Percentage, which meaning "per 100," designates a portion of a total sum. 45 out of 100 is represented by 45%, for instance. Finding the percentage of a whole in terms of 100 is what percentage calculation is. Both manual calculation and the use of internet calculators are options.

The terms "out of 100" and "for every 100" can also be used to refer to percentages. For instance, you may say "it snowed 20% of the time" or "it snowed 20 days out of every 100 days."

A decimal can also be used to represent a percentage. For instance, 24 percent, 0.24, 24/100, or 24 hundredths could also be used to represent the percentage. By dividing the percentage by 10, you can obtain the percent in decimal form.

Given,

The material cost for one headband = $0.95

The cost of one headband sold = $3.80

Now to take the percentage of the cost of material of the headband to the selling price of the headband will be:

= (0.95/3.80) x 100

it can be also written as

= (0.95 x 100)/3.80

Using the angle sum property and the definition of congruency, the measure of angle G is determined to be 118°.

Therefore,

ΔCAT ≅ ΔDOG

m∠C = 25°

m∠O = 37°

The following formula is used to determine angle ∠G:

According to the definition of congruency, the arrangement of the letters in the congruency statement shows that angle ∠C is congruent to angle ∠D, angle ∠A is congruent to angle ∠O, and angle T is congruent to angle ∠G, indicating that we have;

m∠C = m∠D = 25°

m∠A = m∠O = 37°

m∠T = m∠G

The measure of angle ∠G and angle ∠T can therefore, be found from the angle sum property of the interior angles of a triangle.

m∠C + m∠A + m∠T= 180° (angle sum property of a triangle)

m∠D + m∠O + m∠G= 180° (angle sum property of a triangle)

m∠G = 180° - (m∠D + m∠O) (subtraction property of equality)

m∠G = 180° - (25° + 37°) = 118°

The interior angles of triangle add up to give 180 degrees.

The set of all points within a triangle, or all points in the convex hull of the triangle's vertices, is known as the interior of the triangle.

The three angles that make up a triangle's interior are referred to as its interior angles. The total of these three angles is always 180 degrees.

Here given two angles of triangle = 96° and 48°

We know that sum of interior angles = 180°

So x° + 96° + 48° = 180°

x + 144 = 180

x = 180 - 144

x = 36°

To find the value of y,

We know that angle over a straight line is 180°

So ,

96° + y° = 180°

y = 180 - 96

y = 84°
