The general form of the equation of a line in slope intercept form is:
y = mx + c
where:
m is slope
c is y-intercept
An inequality can be represented graphically as a region on one side of a line. Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.
The first inequality with a solid line has a y-intercept of -1 and since it is shaded above the line, we will use ≥.
Two coordinates on the line are: (0, -1) and (1, 2)
The slope = (2 + 1)/(1 - 0) = 3
Thus, inequality is:
y ≥ 3x - 1
The second inequality with a dashed line has a y-intercept of 4 and since it is shaded below the line, we will use <.
Two coordinates on the line are: (4, 0) and (0, 2)
The slope = (2 - 0)/(0 - 4) = -1/2
Thus, inequality is:
y < -¹/₂x + 4

The value of the angle 3 as solved is 52 degrees.
What is the sum of the angles on a straight line?
The sum of the angles on a straight line is always 180 degrees, and this property is true for any pair of opposite angles formed by two intersecting lines.
We can see that what we have is the angles that are on a straight line
We have from the question that;
< 1= 90
<2 = 38
Thus;
<6 = 180 - (90 + 38) - Sum of angles on a straight line
<6 = 52°
Now;
<4 = 90 degrees (Vertically opposite angles)
<5 = 38 degrees (Vertically opposite angles)
Then;
<3 = 180 - (90 + 38) - Sum of angles on a straight line

Which of the following equations describes the
graph below?
Answer:
5x + 3y = - 15
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 0) and (x₂, y₂ ) = (0, - 5) ← 2 points on the line
m = [tex]\frac{-5-0}{0-(-3)}[/tex] = [tex]\frac{-5}{0+3}[/tex] = - [tex]\frac{5}{3}[/tex]
the line crosses the y- axis at (0, - 5 ) ⇒ c = - 5
y = - [tex]\frac{5}{3}[/tex] x - 5 ← in slope- intercept form
multiply through by 3 to clear the fraction
3y = - 5x - 15 ( add 5x to both sides )
5x + 3y = - 15 ← in standard form
What is angle CAB

The measure of the angle CAB in a right angled triangle ABC using given measurements is equal to 37°.
In the triangle ABC,
From the figure we have,
Measure of angle ABC = 90 degrees
Measure of angle ACB= 53 degrees
Sum of all the interior angles of a triangle is equal to 180 degrees .
⇒Measure of angle ABC + Measure of angle ACB + Measure of angle CAB = 180 degrees
⇒ 90° + 53° + Measure of angle CAB = 180°
⇒143° + Measure of angle CAB = 180°
⇒ Measure of angle CAB = 180° - 143°
⇒ Measure of angle CAB = 37°
Therefore, the measure of the angle CAB is equal to 37°.

A set of data items is normally distributed with a mean of 80 and a standard deviation of 9. Convert 71 to a z-score.
271 = 0
(Type an integer or a decimal.)
The z-score for 71 is -1.
Understanding Z-score calculationz-score is a measure of how many standard deviations an observation or data point is away from the mean of a distribution.
It is calculated by subtracting the mean from the observation and then dividing the result by the standard deviation: z = (x - μ) / σ
A positive z-score means that the data point is above the mean, while a negative z-score means that it is below the mean.
Applying the formula to solve our question
Here is a proven formula to use:
z = (x - μ) / σ
where:
x = the data item (x = 71)
μ = the mean of the distribution (μ = 80)
σ = the standard deviation of the distribution (σ = 9)
Substituting the values, we get:
z = (71 - 80) / 9
z = -1

Zeke and his stepmother wanted to start volunteering together. They found 9 opportunities online, 7 of which involved working at an animal shelter.
If they randomly chose to apply to 6 of the opportunities, what is the probability that all of them involve working at an animal shelter?
The likelihood that they will choose to work in an animal shelter for each of the six options they choose is around 0.2214 or 22.14%
The probability is given as,
P = (Favorable event) / (Total event)
The likelihood of choosing an opportunity at an animal shelter is 7/9. If each chance is equally likely to be chosen, the likelihood of choosing six in a row from an animal shelter may be estimated by multiplying the likelihood of choosing one opportunity by itself six times:
P = (7/9) x (7/9) x (7/9) x (7/9)
P = (7/9)⁶

What is a dilation?In Mathematics and Geometry, a dilation is a type of transformation which typically changes the size of a geometric object, but not its shape.
Next, we would have to dilate the coordinates of the preimage by using a scale factor of 9 centered at the point D (-5, 5) by using this mathematical expression:
(x, y) → (k(x - a) + a, k(y - b) + b)
For coordinate B, we have;
Coordinate B = (4, -4) → (9(4 - (-5)) + (-5), 9(-4 - 5) + (-5))
Coordinate B = (4, -4) → (9(9) - 5, 9(-9) - 5)

Sarah is building a 10-foot-long pen for her pet rabbits. She wants to make gravel bases for two circular food containers to go inside the pen along with its width, as shown in the diagram. Let y represent the width of the pen and x represent the radii of the gravel bases and food containers. What system of inequalities can be used to determine the width of the pen, y, and the radii of the gravel bases, x?
1. The width of the pen must be greater than or equal to the sum of the diameters of the two circular food containers, which is equal to 2x + 2x = 4x:
y ≥ 4x2. The width of the pen must also be less than or equal to the length of the pen, which is 10 feet:
y ≤ 103. The radii of the gravel bases must be greater than or equal to the radii of the food containers, which is equal to x:
x ≥ x4. The radii of the gravel bases must also be less than or equal to half the width of the pen, which is equal to y/2:
x ≤ y/2SYSTEM OF INEQUALITIESSystem of inequalities that can be used to determine the width of the pen, y, and the radii of the gravel bases, x, is:
y ≥ 4xy ≤ 10x ≥ 0x ≤ y/2Answer:
Step-by-step explanation:
The sum of the diameters of the gravel bases cannot exceed the width of the pen, so 2x+2x≤y. Rewrite this to get y≥4x as the first inequality in the system.Next, to write the expression for the cost of the fencing, find the perimeter of the rectangle and multiply the perimeter by the cost per foot of fencing. The pen is a rectangle, so the perimeter is 2(10)+2(y), or 20+2y. Multiply the cost ($4.00 per foot) by the perimeter to get 4(20+2y).Now write an expression for the gravel bases for the circular food containers. Because A=πr2 and the cost of the gravel is $2.00 per square foot, multiply the cost of the material by the sum of these areas to get 2(πx2)+2(πx2).The total cost must be less than or equal to $150, so we can say that 4(20+2y)+2(πx2)+2(πx2)≤150. Finally, simplify and solve for y.80+8y+2πx2+2πx2≤15080+8y+4πx2≤1508y≤70−4πx2y≤8.75−0.5πx2So, this is the system.

A slide at a water park with a constant slope sends riders traveling a distance of 45 feet to the pool at the bottom of the slide. If the depth of the pool is 12 feet, and the angle of depression from the top of the slide is 45 ° what is the vertical distance from the top of the slide to the bottom of the pool? Round answers to the nearest tenth.
The required vertical distance from the top of the slide to the bottom of the pool is 43.8 feet.
We can use trigonometry to solve this problem. Let's call the vertical distance from the top of the slide to the bottom of the pool "h" (in feet). We can use the angle of depression (45°) to find the horizontal distance from the top of the slide to the bottom of the pool. Since the slide has a constant slope, the angle between the slide and the ground is also 45°. It implies that the vertical height is equal to the horizontal projection of the slide.
Apply Pythagorean theorem,
45² = h² + h²
h = 45/√2
h = 31.8
Now, as mentioned that depth of the pool is 12 feet so, the total vertical height is given as,
= h + 12
= 31.8 + 12
= 43.8 feet
Thus, the required vertical distance from the top of the slide to the bottom of the pool is 43.8 feet.
