Given the line 2x - 3y - 5 = 0, find the slope of a line that is perpendicular to this line.
Answer:
The slope of the line would be -3/2.
Step-by-step explanation:
Let's get this equation into the proper slope form:
2x - 3y - 5 = 0
2x - 3y + 3y - 5 = 0 + 3y
2x - 5 = 3y
(1/3)(2x - 5) = 3y * 1/3
2/3x - 5/3 = y
Since the slope is 2/3, we need to find the negative reciprocal of that number, which is -3/2.
First of all, we need to add 5 on both sides :
2x-3y=5
Now, subtract 2x on both sides ↓
-3y=5-2x
Or
-3y=-2x+5
Now we need to divide by -3 on both sides to get y all by itself ↓
y=-2/-3+5/-3
[tex]\boxed{\\\begin{minipage}{2cm}y=$\displaystyle\frac{2}{3} x-\frac{5}{3}$ \\ \end{minipage}}[/tex]
Now determining the slope is facile.
If lines are perpendicular to each other, they
Intersect at a 90º angleHave slopes that are opposite reciprocalsIn order to find the opposite reciprocal of a fraction, we need to switch the numerator & the denominator places and then change the fraction's sign as follows ↓
(slope = 2/3)
Switch the numerator and denominator places ↓
3/2
Change the fraction's sign ↓
-3/2
Therefore the slope's -3/2hope helpful ~

( just keep the first fraction as it is, change the divide sign to a multiply and flip the second fraction upside down. )
Answer:
35/4 or 8 3/4.
Step-by-step explanation:
-7 / -4/5
Invert the second fraction and multiply:
= -7 * -5/4
= 35/4
= 8 3/4.

Answer:
Triangles A and B
Step-by-step explanation:
Similar triangles have congruent corresponding angles. Triangles a and b both have angle measures of 90°, 23° and 67°. Triangle C has different angle measures therefore it cannot be similar to either triangle A and B.
Similar triangles also have similar side length ratios via corrsesponding sides. This is true for triangles A and B eg. have corresponding side length ratios of 24/12 , 26/13 and 10/5 which all equal 2
So we can conclude triangles A and B are similar
there are five geometric mean between a and b. if second and last mean are 2 and 16 respectively, find the value of a and b.
Answer:
a = 1/2, b = 32.
Step-by-step explanation:
Second = a1r and fifth = a1r^4 where r = common ratio and a1 is the first mean after a.
So 1ar^4 / a1r = r^3 = 16/2
r^3 = 8
r = 2.
So a1 = 1.
The 5 means are 1, 2, 4, 8, 16
S0 a = 1/2 = 1/2 and b = 2*16 = 32.
what is 3/4 - 3/8 = in simplest form
Answer:
3/8
Step-by-step explanation:
We have to use a common denominator of 8 for this problem. 3/4 = 6/8. 6/8 - 3/8 is 3/8. 3/8 is in its simplest form, so that would be the answer.
Answer:
3/8
Step-by-step explanation:
Reduce the fraction to lowest terms
1 is the greatest common divisor of 3 and 8. The result can't be further reduced.

Answer:
Number line 3 also known as [C]
Step-by-step explanation:
Given that:
c ≤ -1
Knowing that:
≤ = Less than or equal to
Now substitute into the equation:
C less than or equal to -1
Thus, it going left on a number line.
The only number line with left is [A] and [C]
Since ≤ = Less than or equal to -1
then, it including -1
also known as a closed circle means the number is included and an open circle means it is not.
Hence, it closed circle.
Thus, the answer is [C]

Marina bought a bag of 10 chocolate cookies, 35 vanilla cookies, and 30 peanut butter cookies.
If she selects a cookie from the bag without looking, what is the probability she selects a peanut butter cookie?
Answer:
[tex]\frac{2}{5}[/tex]
Step-by-step explanation:
1) Add all the values.
= 10 + 35 + 30
= 75
2) 75 will be the denominator and the one required will be the numerator.
Since there are 30 peanut butter cookies, the probability is [tex]\frac{30}{75}[/tex].
3) Simplify the fraction if necessary.
Divide both sides by 15.
= [tex]\frac{2}{5}[/tex]

The results of a poll show that between 74% and 82% of consumers prefer Chip A to Chip B. What is the point estimate for the percent of consumers that prefer Chip A to Chip B?
74%
78%
82%
8%
Answer:
78%
Step-by-step explanation:
First of all, the point estimate is a value located in between the upper confidence limit and the lower confidence limit, it identifies a point in some parameter space.
This question provides us with an interval estimate which is a range of values used to estimate a population parameter.
Interval Estimate = 74% to 82%
74% = Lower confidence limit
82% = Upper confidence limit
Point estimate = middle value
= [tex]\frac{74+82}{2}=\frac{156}{2}[/tex]
= 78%

Step-by-step explanation:
Your going to have the divide y by x so (y ÷ x)
5÷2 = 2.5
10÷4 = 2.5
15÷6 = 2.5
They all end up having the same answer. So when you divide y by x, you have to have the same answer for every single one.

In order to estimate how many pizzas were eaten, we need to subtract the amount of pizza left from the original amount. The amount of pizza left is 5/6 + 1 3/4. 5/6 is about 1 and 1 3/4 is about 2. 1 + 2 = 3 pizzas eaten.
The original amount of pizzas, 8, minus the amount of pizzas eaten, 3, is 5.. We can estimate that 5 pizzas were eaten.

4x - 2y = 12
x + 2y = 8
(to cancel 2y, solve by adding)
4x - 2y = 12
+
x + 2y = 8
4x + x = 5x
-2y + 2y = 0
12 + 8 = 20
5x = 20
÷5
x = 4
Substitute x=4 to one of the equation:
x + 2y = 8
4 + 2y =8

2y. = 4
÷2
y. = 2
Check:
4 + (2x2) does give you 8
