The equation of each line given the y-intercept and x-intercept

5 and -4 is 4y- 20 = 5x.

The line has an x-intercept at x = -4 and y intercept at y = 5 this means that the line passes through the points(,0) and(,5).

Now we find the pitch m of the line passing through the points(,0) and(,5)(x-intercept).

The pitch of the line is

m = y2- y1/ x2- x1

= 5- 0/ 0-(- 4)

= 5/ 4

Point- pitch Formula y = m(x-x1)

where m is the pitch and( x, y) is the given point.

Now substituting the values

y- 0 = (5/4)( x-(- 4))

y = (5/4)( x 4)

4y- 20 = 5x

Ex. 32 + 32 = 64

Answer:

The graph of the line x = 12 is a vertical line.

A vertical line is a line with a constant x-value, in this case x = 12, so all the points on the line will have an x-coordinate of 12, regardless of their y-coordinate. All the point on the line will have the same x-coordinate and it will be parallel to the y-axis.

It does not have a slope, does not cross the y-axis, it is not horizontal.

Answer:

x = 5, y = 1

Step-by-step explanation:

2x - y = 9

2x + y = 11         subtract equation 2 from equation 1

0 - 2y = -2

y = -2/-2 = 1       substitute into equation 1 or 2 to solve for x

2x - 1 = 9

2x = 10

x = 10/2 = 5

Solving a system of equations we will see that the efficiency of the first car is 25 miles per gallon, and the one of the second car is 35 miles per gallon.

Let's define the variables:

x = fuel efficiency of the first car.

y = fuel efficiency of the second car.

We know that the sum is equal to 60 miles per galon, thus:

x + y = 60

We also know that the he first car consumed 35 gallons of gas and the second consumed 20 gallons of gas. The two cars drove a combined total of 1575 miles, this can be written as:

35x + 20y = 1575

Then we have a system of equations:

x + y = 60

35x + 20y = 1575

We can isolate x on the first equation to get:

x = 60 - y

And substitute that in the other equation:

35*(60 - y) + 20y = 1575

2100  - 15y = 1575

2100 - 1575 = 15y

525/15 = y

35 = y

And x = 60 - y = 60 - 35 = 25

These are the efficiencies.

Answer:

The correlation coefficient of 0.29 indicates that the correlation is a weak positive correlation. Thus option (D) is the correct answer.

What is correlation?

"Correlation is a statistical tool that studies the relationship between two variables. Data sets have a positive correlation when they increase together, and a negative correlation when one set increases as the other decreases".

For the given situation,

Correlation coefficient = 0.29

Positive correlation: the two variables change in the same direction.

Negative correlation: the two variables change in opposite directions.

No correlation: there is no association or relevant relationship between the two variables.

The correlation coefficient lies between 0 to 0.3 indicating that the correlation is a weak positive correlation.

Hence we can conclude that option (D) weak positive correlation is the correct answer.

When the line of slope of 3 passes through two points, the value of y is -8.

The slope or gradient of a line in mathematics is a number that describes both the direction and the steepness of the line. The slope of a line indicates its steepness. Slope is calculated mathematically as "rise over run" (change in y divided by change in x). The slope is a numerical value that describes the steepness of a line and is typically calculated by dividing the vertical distance by the horizontal distance (rise over run) between two points.

Here,

m=3

m=(y2-y1)/(x2-x1)

3=(y+5)/(-3+(2))

-3=y+5

y=-8

The value of y is -8 when the line of slope of 3 is passing through 2 points as given.

The incenter is where a triangle's angle bisectors meet. Since C is the incenter, segment BC should be the angle bisector. So, there is an error in line 3; segment AB and BC are congruent.

Any triangle with any 2 sides that are the same length is defined as an isosceles triangle. An isosceles triangle has two equal-sized angles that are opposite from one other and have equal sides.

If all three angles of the three triangles are acute, the circumcenter of an isosceles triangle sits inside the triangle. The circumcircle's chords are the sides of the triangle. In this case, the circumcenter is outside of the triangle since one of the angles is 90 degrees.

The circumcenter of a triangle ABC is the location where the perpendicular bisectors of its sides cross.

There is good evidence that smoking rates for young teens in Massachusetts have decreased.

To answer this question, we need to calculate the proportion of teens in the sample who said they smoked (63/273). This gives us a sample proportion of 0.23, which is lower than the long-run average smoking prevalence in the state (26%). This suggests that there is good evidence that smoking rates for young teens have decreased.

We can also calculate a confidence interval to further assess the evidence. A 95% confidence interval for the true proportion of teens in Massachusetts who smoke would be (0.17, 0.29). This confidence interval does not contain the long-run average smoking prevalence of 26%, which suggests that there is a statistically significant decrease in smoking rates for young teens in Massachusetts.

Overall, there is good evidence that smoking rates for young teens in Massachusetts have decreased.

Answer: (-5x+3) - (-7x7) = -5x + 3 - (-7x7) = -5x + 3 + 7x7 = 2x7

The expression (-5x+3) - (-7x7) is the result of subtracting two algebraic expressions. When subtracting algebraic expressions, we need to distribute the negative sign to each term before combining like terms.

The first step is to distribute the negative sign to each term in the second expression, (-7x7). This gives us:

(-5x+3) - (-7x7) = -5x+3 + 7x7

Now we can combine the like terms, x7, to get the simplified expression:

-5x+3 + 7x7 = 2x7

So the final answer is 2x7.

A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The sum of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse. ​

1) Area of design = area of rectangle + 2(area of triangle)

Area of design = (60×30) + 60×45

Area of design = 1800 + 2700

Area of design = 4500 ft²

2) Area covered by grass =  2(area of triangle)

Area covered by grass =   = 60×45

Area covered by grass = 2700 ft²

3) installment of grass is $0.55 per ft².

If the relationship between his hours of work (x) and the amount of money in his bank account (y) is represented by equation "y = 10x + 50" , then the money did he have in his bank account before he started working is $50 .

The equation y = 10x + 50 shows the relationship between Hamal's hours of work (x) and the amount of money in his bank account (y).

When x = 0, the equation becomes y = 10(0) + 50, which simplifies to y = 50. So when Hamal has not worked any hours, he has $50 in his bank account.

The length of the rectangular field is 200 meters.

Given, we have length of the field equal to twice its breadth. Let the breadth of the field be "b". Therefore, length will be "2 x b". Now, Meghna jogged around the field 5 times which means she covered the perimeter of the field 5 times. We know that the perimeter of a rectangular field is [tex]2(l+b)[/tex] where l is the length of the rectangle and b is the breadth.

After jogging around the field 5 times, she covered a distance of 3 km. Converting kilo meters into meters: 3km ⇒ 3 x 1000 =  3000 meters. Now, We can equate the perimeter of the rectangle with  the given information like this :

⇒[tex]2(l+b) * 5 = 3000m[/tex]

We already know that length = 2b, therefore putting in the equation gives us :

⇒ 2(2b+b) x 5 = 3000m

⇒2(3b) x 5 = 3000m

⇒10(3b) = 3000m

⇒30b = 3000m

Dividing both sides of the equation with 30,

⇒b = 100 m

Since, length = 2b, Therefore Length ⇒ 2 x 100m = 200m
