Write in slope intercept form.
15x − 4y = 11
Answer:
y = 15/4x - 11/4
Step-by-step explanation:
Slope-intercept form of the line 15x - 4y = 11 is y = (15/4)y + 11/4.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
We know the equation of a line in slope-intercept form is y = mx + b.
∴ 15x − 4y = 11 can be written as - 4y = - 15x + 11 ⇒ y = (15/4)y + 11/4.

The diagram shows a right-angled triangle. 37° 15 cm cm What is the value of h? Give your answer correct to 1 decimal place.
[tex]tan = \frac{opp}{adj} [/tex]
[tex] \tan(37) = \frac{opp}{15} [/tex]
[tex]h = 15 \tan(37) [/tex]
[tex]h = 11.3 \: cm[/tex]
Answer:
h ≈ 11.3 cm
Step-by-step explanation:
Using the tangent ratio in the right triangle.
tan37° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{h}{15}[/tex] ( multiply both sides by 15 )
15 × tan37° = h , that is

What should Satish's balance in his register be? A. $610.82, B.$792.91, C.$910.82, or D.$947.14
Answer:
Balance = $195.56

Feb 4 deposit = $150.00
Feb 7 deposit = $225.56
Total credit = $375.56
Debit:
Feb 5 ATM withdrawal = $180
Total Debit = $180
Balance = credit - debit
= $375.56 - $180
= $195.56
Balance = $195.56
The answer is not included in the option. It is either the options are not correct or the values in the question are not correct. Please recheck

The Skateboard club has 2 different colours of skateboards Blue and Red. Can you find the number of skateboards of each colour, if the total number of skateboards is 15, and their product is 44
Answer: 11 and 4 respectively
Step-by-step explanation:
Let's denote the number of skate board for each color by x and y.
x + y = 15 ......... i
x × y = 44 .......... ii.
From equation I
x = 15 - y ....... iii
Put equation iii into ii.
x × y = 44
(15 - y) × y = 44
15y - y² = 44
15y - y² - 44 = 0
y² - 15y + 44 = 0
y² - 11y - 4y + 44 = 0.
y(y - 11) + 4(y - 11) = 0
(y - 4) = 0. .
y = 0 + 4.
y = 4
(y - 11) = 0
y = 0 + 11 = 11
The colors have 11 and 4 colors of blue and red respectively

A freight elevator has a weight limit of 15,000 pounds. Workers have loaded items weighing 2.6 tons onto the elevator. How many more pounds of freight can they load before reaching the weight limit?
Given :
A freight elevator has a weight limit of 15,000 pounds.
Workers have loaded items weighing 2.6 tons onto the elevator.
To Find :
How many more pounds of freight can they load before reaching the weight limit.
Solution :
We know, 1 ton = 2000 pounds.
So, 2.6 ton = 2.6 × 2000 = 5200 pounds.
Now, number of pounds of freight can be loaded before reaching the weight limit is :
N = 15000 - 5200 pounds
N = 9800 pounds

All the members of a school chorus are either students or employees.The ratio of students to employees is 2:5 and the chorus has 70 members. How many employees are members of the chrous?
Answer:
50 employees are members of the chorus
Step-by-step explanation:
Total number of chorus members = 70
ratio of students to employees = 2:5
This means that if the total number of employees were to be divided into 7 parts (2 + 5), 2 parts will be students while 5 parts will be employees. Now let us convert this fraction/ratio to numbers. This is done as follows:
students to employees = 2:5
∴ employees to students = 5:2
Total parts of employees and students = 5 + 2 = 7
∴ Number of employees
[tex]= \frac{5}{7}\ of\ 70\\= \frac{5}{7} \times \frac{70}{1}\\= \frac{350}{7} = 50\ members[/tex]
∴ 50 members are employees, while the remaining 20 are students

The inscribed angle is a point in the circle that has endpoints also in the circle. The value of the inscribed angle is half the value of the arc formed by the endpoints.
So, If the arc FJ is 84°, we have that the angle in point G isi 84/2 = 42°
A rectangle has a length of 80 cm and a width of 50 cm. The rectangle is dilated by a scale factor of 3.5 to create a
new rectangle
What is the area in square centimeters of the dilated rectangle?
Answer:
49,000
Step-by-step explanation:
To get the area of the dilated rectangle, we need the dilated dimensions
We simply multiply the scale factor by the dimensions
we have this as;
3.5 * 50 = 175 cm
and
3.5 * 80 = 280 cm
The area of the dilated rectangle is thus;
280 * 175 = 49,000 cm^2
A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
The area of the dilated rectangle is 49,000 cm²
Example:
The area of the dilated rectangle in square centimeters is 49,000 cm²
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Length = 80 cm
Width = 50 cm
Dilated with a scale factor = 3.5
We will multiply 3.5 with the length and width of the rectangle.
The dilated length = 3.5 x 80 = 280 cm
The dilated width = 3.5 x 50 = 175 cm
The area of the dilated rectangle.
= 280 x 175
= 49000 cm²
Thus,
The area of the dilated rectangle in square centimeters is 49,000 cm²

Answer:
A statistic is a characteristic of a sample, a portion of the target population. A parameter is a fixed, unknown numerical value, while the statistic is a known number and a variable which depends on the portion of the population.
Answer:
This is hw you do it
Step-by-step explanation:
A statistic and a parameter are very similar. They are both descriptions of groups, like “50% of dog owners prefer X Brand dog food.” The difference between a statistic and a parameter is that statistics describe a sample. A parameter describes an entire population

What is its average speed rounded to the nearest whole number?
what are the coordinates of A after reflecting across the line x = 3? (2, 3)
(3, 2) (3, 4) (3, -2)
Answer:
Here we can not see point A, so i will answer in a general way.
Let's suppose that point A is (a, b)
Now, if we do a reflection over a given line, the (perpendicular) distance between our original point to the line is the same as the distance between the reflected point and the line.
So for example if we have the point (x, y) and we do a reflection over the line x = k.
The distance between our point and the line is:
x - k
So the new point must be also at a distance of (x - k) from line x = k.
The only other point that meets this condition is (k - (x - k), y) = (2k - x, y)
Now remember that point A is (a, b)
And we do a reflection over x = 3
The distance between our point and the line is:
D = I(a - 3)I
Then the reflection will be:
(3 - (a - 3), b) = (6 - a, b)
Where (a, b) where the original coordinates of point A.

The perimeter of a rectangle with a length of 10 units which equation can be used to find the width of the rectangle
Answer:
2w + 20 = 55
Step-by-step explanation:
Here is the full question
The perimeter of a rectangle with a length of 10 units is 55 units. Which equation can be used to find the width, w, of the rectangle?
w + 10 = 55
w + 20 = 55
2w + 10 = 55
2w + 20 = 55
The perimeter of a rectangle's formula is = 2 ( length + breadth)
from the question ,
perimeter is 55 and length is 10
2(10 + w) = 55
20 + 2w = 55
