what is the equation of the line that passes through the point (8,4) and has a slope of 3/2 ?
Answer:
y = 3/2x - 8
Step-by-step explanation:
y = 3/2x + b
4 = 3/2(8) + b
4 = 12 + b
-8 = b

Consider this equation: 0B = 21. Is the equation always false, no matter what value you give the variable? Justify your answer.
Answer:
because the variable is being multiplied by 0.
Step-by-step explanation:
the B in the equation is just a place holder for any number you can think of.
the problem with that is that any number times 0 will always give you 0, so the equation will look like this now
0 = 21
this equation is false because 0 is not equal to 21.
21 is equal to 21.

Find the slope of the line.
Answer:
The Slope of a line formula is given by
m=y2 - y1/ x2 - x1
Now Form a triangle using the straight line(It'd be best if you choose known Points on the graph)
Picking points (1, 2) and (2, 5) connect these points and you'll have a small triangle.
x1 y1 x2 y2
Substituting into the formula
m=5-2/2-1
m=3.

Answer:
2) Slope=10/3
Step-by-step explanation:
2. Use the equation y2-y1/x2-x1. In this line, I took the points (-4,-5) and (-1,5). Plug this into the equation to get 5--5/-1--4. Simplify this to get 5+5/-1+4. Simplify this to get 10/3. Therefore, the slope is 10/3
4. The equation is y=mx+b where m is the slope and b is the y-intercept. This means that the equation will be 8/3x-5.

he total cost of a vase of spring flowers at a flower shop depends on the number of flowers ordered. The vase costs $3, and each flower costs $2.50. Which equation can be used to findc,the total cost of the vase withfflowers?
Answer:
3+2.50x
Step-by-step explanation
x represents how many flowers you bought which you mulitply with 2.50 since each flower is 2.50 dollars. Then you add 3 since the cost of the vase is 3 dollars.

Find the measure of side c. Triangle A B C has a right angle at angle C. The measure of angle A is 29 degrees. Hypotenuse A B is labeled "c" and leg B C is labeled "a = 33 meters." 29 o c a = 33 m
Given:
In triangle ABC, right angle at angle C.
[tex]a = 33[/tex] meters
[tex]m\angle A=29^\circ[/tex]
To find:
The measure of side c.
Solution:
In a right angle triangle,
[tex]\sin \theta =\dfrac{Perpendicular}{Hypotenuse}[/tex]
It is also written as:
[tex]\sin \theta =\dfrac{Opposite}{Hypotenuse}[/tex]
In triangle ABC, angle C is a right angle. It means the side c is the hypotenuse.
In triangle ABC,
[tex]\sin A=\dfrac{a}{c}[/tex]
[tex]\sin 29^\circ=\dfrac{33}{c}[/tex]
[tex]c=\dfrac{33}{\sin 29^\circ}[/tex]
On further simplification, we get
[tex]c=\dfrac{33}{0.4848}[/tex]
[tex]c=68.0693[/tex]
[tex]c\approx 68.07[/tex]
Therefore, the measure of side c is 68.07 meters.

In a group of 24 people, 10 study
Physics, 15 study Chemistry and
18 study at least one subject.
Find the number of people who
do not study any of the subject.
Show steps pls
Answer:
n = 24
p(a) = 10/24
p(b) = 15/24
[ p(a) + p(b) - [p(a) ×p(b)] ] -1 = answer
[ 35/24 - 6/24 ] -1 = 39/24 - 24/24 = 5/24
=================================================
Explanation:
There are 24 people total and 18 of them study at least one subject. So that must mean 24 - 18 = 6 people do not study any of the subjects mentioned.
The values of 10 and 15 aren't used at all.

A sample proportion of 0.78 is found. To determine the margin of error for this statistic, a simulation of 100 trials is run, each with a sample size of 50 and a point estimate of 0.78. The minimum sample proportion from the simulation is 0.62, and the maximum sample proportion from the simulation is 0.80. The margin of error of the population proportion is found using half the range. What is the interval estimate of the true population proportion?
1. (0.74, 0.82)
2. (0.64, 0.92)
3. (0.72, 0.84)

Answer:
f(x) = -½x + 16
Step-by-step explanation:
Using two points in the line, (0, 16) and (4, 14), we can write an equation for the linear function in the slope-intercept form, f(x) = mx + b, by finding the slope (m) and the y-intercept (b), then substituting each of the value into f(x) = mx + b.
✔️Slope (m) = change in y/change in x
Using, (0, 16) and (4, 14),
Slope (m) = (14 - 16)/(4 - 0) = -2/4
m = -½
✔️y-intercept (b) would be the value of y when x = 0, or the point at which the y-axis is intercepted by the line.
Thus,
When x = 0, y = 16
Therefore,
b = 16
✅Write the equation of the function by substituting m = -½ and b = 16 into f(x) = mx + b
Thus:
f(x) = -½x + 16
