Answer:
x = -1/4
Step-by-step explanation:
Find the equation of the line that passes through points (0, 2) and (1, 1). (Slope)
m = (1 - 2) / (1 - 0) = -1
The equation of the line in slope intercept form is
y = mx + b
We have
m = -1
b = 2 (The y-intercept is given)
Substitute
y = -x + 2 (Equation A)
Now solve the system of equations
y = -x + 2 (Equation A)
y = 3x + 3 (Equation B)
Solve the system by substitution, equate equation A and equation B
3x + 3 = -x + 2
Solve for x
3x + x = 2 - 3
4x = -1
x = -1/4
Therefore, the x-coordinate of the intersection both lines is 1/4

A deli sells 2 hot dogs for $2.50. What is the constant of proportionality of dollars per hot dog?
Answer:
$1.25 per hot dog
Step-by-step explanation:
Since we have given that
A deli sells 2 hot dogs for $2.50
i.e.
Cost of 2 hot dogs = $2.50
And we need to find the constant of proportionality of dollars per hot dog, for which we'll use unitary method.
So,
Cost of 1 hot dog is given by
2.50/2=$1.25
So, Cost of per hot dog is $1.25.

Evaluate the expression 53 ÷ (13 − 8) × 2.
Answer:
im confused too so lets work together!
Step-by-step explanation:
(13 - 8 = 5.) so, rewrite the problem as 5 cubed divided by (5) x 2! Now, we figure out 5 cubed. 5 x 5 equals 25, x 5 equals 125. So, 125 divided by 5 would be 25. Now, 25 x 2 is 50.
The final answer would be 50!

1. A piece of steel has a volume of 12 cm3
and a mass of 96g. What is its density?
Answer:
it's density is 8 g /cm³
Step-by-step explanation:
Mass (m) = 96 g
Volume (v) = 12 cm³
Density (d) =?
We know density is defined as mass per unit volume so
d = m/v
= 96 / 12
= 8 g/cm³
Hope it will help :)
Note : if in the question it is said to write in sI system u have to write in kg/m³.

Step-by-step explanation:
<AOP + < BOP = 180°< being linear pair >
x + 30° + x - 30° = 180°
2x = 180°
x = 90°
Now
<AOP = x + 30° = 90° + 30° = 120°
<BOP = x - 30° = 90° - 30° = 60°
<AOP is obtuse angle because it is less than 180° but more than 90°.<BOP is acute angle because it is less than 90°.Hope it will help :)❤

The Montgomery Company tells Squeaky Clean that most of their buildings are 40 feet tall. Squeaky Clean decides to use ladders to reach the upper windows. The base of the ladder works best on the sidewalk so it needs to be 9 feet away from the building. How tall should the ladder be in order to reach the top of the building?
Answer: 41 feet
Step-by-step explanation: The ladder, the building and the sidewalk creates a right triangle, with the 90° formed at the junction of sidewalk and building, so the length of the ladder is the triangle's hypotenuse.
To determine hypotenuse, use Pythagorean's theorem:
[tex]h^{2}=s^{2}_{1}+s^{2}_{2}[/tex]
[tex]h=\sqrt{40^{2}+9^{2}}[/tex]
[tex]h=\sqrt{1681}[/tex]
h = 41
For the ladder to reach the top of the building, it has to be 41 feet tall.
Complete the following sentence
If x is to 6 as 10 is to 15, then x is equal to .
Answer:
x=4
Step-by-step explanation:
x/6 = 10/15
x/6 = 2/3
3x=12
Answer:
x=4
Step-by-step explanation:
To find this, you must first figure out the relationship between 10 and 15. Since 10 is 2/3 of 15, "x" must be 2/3 of 6.
To find "x", divide 6 by 3 to get 2, then 2 by 2 to get 2/3 of 6 (4). Thus meaning X = 4.

Which ratio is equivalent to the ratio 32:40?
Answer:
4/5, or 4:5
Step-by-step explanation:
Roxanne likes to fish. She estimates that 30% of the fish she catches are trout, 20% are bass, and 10% are perch. She designs a simulation.
Let 0, 1, and 2 represent trout.
Let 3 and 4 represent bass,
Let 5 represent perch.
Let 6, 7, 8, and 9 represent other fish.
The table shows the results:
The probability helps us to know the chances of an event occurring. The probability of Roxanne catching bass is 60%.
What is Probability?The probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
For the next four of the fishes to be bass, the numbers in the table must contain the digit 3 or 4 in it. Therefore, the cases where Roxanne catches bass are:
263520534526699443483087832335793840683933637683Also, it is mentioned that the total number of cases is 20 (Given in the table). Therefore, the probability of catching a bass can be written as,
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}\\\\\\Probability=\dfrac{\text{Number of cases where Roxanne catches fish}}{\text{Total number of catches}}\\\\\\Probability = \dfrac{12}{20} = 0.60\\\\Probability = 60\%[/tex]
Hence, the probability of Roxanne catching bass is 60%.

Find the common ratio and the three terms in the sequence after the last one given. -4, 16, -64, 256, …
Answer:
The ratio of all the adjacent terms is the same and equal to
[tex]r=-4[/tex]
The next three terms after the last one will be:
[tex]a_5=-1024[/tex][tex]a_6=4096[/tex][tex]a_7=-16384[/tex]Step-by-step explanation:
Given the sequence
-4, 16, -64, 256, …
Finding the common ratio
An arithmetic sequence has a constant ratio 'r' and is defined by
[tex]a_n=a_1\cdot r^{n-1}[/tex]
computing the ratios of all the adjacent terms
[tex]\frac{16}{-4}=-4,\:\quad \frac{-64}{16}=-4,\:\quad \frac{256}{-64}=-4[/tex]
The ratio of all the adjacent terms is the same and equal to
[tex]r=-4[/tex]
Finding the next three terms
Given the sequence
-4, 16, -64, 256, …
here
[tex]a_1=-4[/tex]
[tex]r=-4[/tex]
substituting [tex]a_1=-4[/tex] and [tex]r=-4[/tex] in the nth term
[tex]a_n=a_1\cdot r^{n-1}[/tex]
[tex]a_n=-4\left(-4\right)^{n-1}[/tex]
substituting n = 5 to determine the 5th term
[tex]a_5=-4\left(-4\right)^{5-1}[/tex]
[tex]a_5=-4^4\cdot \:4[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]
[tex]a_5=-4^{1+4}[/tex]
[tex]a_5=-4^5[/tex]
[tex]a_5=-1024[/tex]
substituting n = 6 to determine the 6th term
[tex]a_6=-4\left(-4\right)^{6-1}[/tex]
[tex]a_6=-4\left(-4^5\right)[/tex]
[tex]\mathrm{Apply\:rule}\:-\left(-a\right)=a[/tex]
[tex]a_6=4\cdot \:4^5[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]
[tex]a_6=4^{1+5}[/tex]
[tex]a_6=4^6[/tex]
[tex]a_6=4096[/tex]
substituting n = 7 to determine the 6th term
[tex]a_7=-4\left(-4\right)^{7-1}[/tex]
[tex]a_7=-4^6\cdot \:4[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]
