find the equation of the line that passes through a and b
Answers
y = 2x - 1
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 = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = A(4, 7) and (x₂, y₂ ) = B(2, 3)
m = = = 2, thus
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation.
Using B(2, 3), then
3 = 4 + c ⇒ c = 3 - 4 = - 1
y = 2x - 1 ← equation of line

There were 28 boys on the boy's basketball team and 16 girls on the girl's basketball team last year. This year the number of boys decreased by 8% but the number of girls increased by 19%. Was there an increase or decrease in overall participation?
Answers
The sum of participants last year was 44 students, but this year was only 37.80 participants.
There is an increase in total participants.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
number of boys = 28
Number of girls = 16
Total participants = 28 + 16 = 44
Now, there is decrease in number of boys by 8%
= 28- 8% x 28
=28- 8/100 x 28
=28 - 0.08*28
=28 -2.24
= 25.76
and, there is 19% increase in number of girls
=16 + 0.19 x 16
=16 + 3.04
=19.04
So, total participants = 25.76 + 19.04
= 44.8
Hence, there is an increase in total participants.

What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
In any equilateral triangle, the three angles are of equal measure and they equal 60 degrees.
When we drop a perpendicular that is the height of the triangle we have a 30 -60 90 triangle.
The hypotenuse = 8
Let, perpendicular = a and base = 4
According to Pythagoras theorem,
A right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
perpendicular²+base² = hypotenuse²
a² + (4)² = (8)²
a² + 16 = 64
a² = 64 - 16
a² = 48
a = √48
a = 4√3
Hence, the altitude of the triangle is 4√3

8. A line passes through the points (0-2) and (0,5). Is it possible to write an equation of the line in
slope-intercept form? Justify your answer.
Answers
Answer: No
Step-by-step explanation:
There is no slope
It is not possible to write the equation of the line passing through (0, -2) and (0, 5), because slope is not defined.
What is Slope?Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.
Given that a line passes through two points (0, -2) and (0, 5).
Both the points are on Y axis.
Therefore the line is along the Y axis.
Slope of a line along the Y axis is not defined since the Y axis is making 90° with the X axis and tan 90° is the slope, which is not defined.
Or in other words, taking the given points,
slope = change in y coordinates / change in x coordinates
= (5 - -2) / (0 - 0)
= 7 / 0, not defined.
Hence the equation of the line along the Y axis cannot be written in the slope intercept form as the slope is undefined.

At the supermarket, you can fill your own honey bear container. A customer buys 12 oz of honey for $5.40.
How much does honey cost per ounce?
How much honey can you buy per dollar? Round to the nearest hundredth.
Answers
Answer: a. $0.45; b. 2.22 oz
Step-by-step explanation:
From the question, we are informed that acustomer buys 12 oz of honey for $5.40.
a. How much does honey cost per ounce?
To calculate this, we divide $5.40 by 12oz. This will be:
= $5.40/12
= $0.45
b. How much honey can you buy per dollar?
Since 1 ounce cost $0.45, the number of honey that can be bought for $1 will be:
= $1/$0.45
= 2.22 oz

The formula t=√h/4 represents the time t in seconds that it takes an object to fall from a height of h feet. If a rock falls from a height of 125 feet, estimate how long it will take to reach the ground
Answers
Answer:
it would take 14mph
Step-by-step explanation:
A function assigns the values. The time it will take for the rock to reach the ground from a height of 125 feet is 2.795 seconds.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given that the formula t=√h/4 represents the time t in seconds that it takes an object to fall from a height of h feet.
Now, in order to calculate the time, it will take for the rock to fall from the height of 125 feet, simply substitute the height of the rock from which it is dropped in the formula given.
Therefore, the time it will take for the rock to reach the ground from a height of 125 feet is,
t = √h / 4
t = (√125) / 4
t = (5√5) / 4
t = 2.795 seconds
Hence, the time it will take for the rock to reach the ground from a height of 125 feet is 2.795 seconds.

and m\angle B=(4x-14)^{\circ}∠B=(4x−14)
∘
, then find the measure of \angle A∠A.
Answers
Answer:
the measure of ∠A. is 87∘
Step-by-step explanation:
Two angles are said to be supplementary angles if the sum of those angles is 180 degrees.
_________________________________________________
Given
∠A=(4x−30) ∘
∠B=(4x−14) ∘
Fir angles to be supplementary
∠A + ∠B = 180
(4x−30) ∘ + (4x−14) ∘ = 180∘
(8x -54 )∘ = 180∘
=> 8x = 180∘ + 54∘= 234∘
=> x = 234∘/8 = 29.25∘
Thus,
∠A=(4x−30) ∘
∠A=(4*29.25−30) ∘ =( 117 - 30 ) ∘ = 87∘
Thus,
the measure of ∠A. is 87∘
