can you help me graph -3y<2x+9
Answer:
Step-by-step explanation:
please help:)I’m not good at math and need to get this done ASAP
Answer:
First and third options are equivalent, second and fourth options are not equivalent.
Step-by-step explanation:
Remember the relation:
[tex]a^n*a^m = a^{n + m}[/tex]
and:
[tex](a^n)^m = a^{n*m}[/tex]
We have the expression:
[tex]7^{1/5}*49^{7/5}[/tex]
We know that 49 = 7*7
Then we can write the above relation as:
[tex]7^{1/5}*49^{7/5} = 7^{1/5}*(7^2)^{7/5}[/tex]
We can use the second relationship from the above ones and write this as:
[tex]7^{1/5}*(7^2)^{7/5} = 7^{1/5}*7^{2*7/5} = 7^{1/5}*7^{14/5}[/tex]
Now we can use the first relationship to get:
[tex]7^{1/5}*7^{14/5} = 7^{1/5 + 14/5} = 7^{15/5} = 7^3 = 343[/tex]
Then:
The first option is equivalent.
The second option is not equivalent
The third option is equivalent.
The fourth option is not equivalent.
1.When two variables are proportional which of the following is constant?
(1) their sum
(3) their product
(2) their ratio
(4) their difference
Answer:
Their Ratio
Step-by-step explanation:
You switched the numbers 2 and 3 btw
[tex]\boldsymbol{\left ( 2 \right )}[/tex] their ratio
A ratio indicates how many times one number contains another.
Two sequences of numbers, often experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, which is called the coefficient of proportionality or proportionality constant.
When two variables are proportional, [tex]\boldsymbol{\left ( 2 \right )}[/tex] their ratio is constant.

HELP! WHY IS THIS TRIANGLE CONGRUENT! EASY PLS HELP
Answer:
D. xz=yz, angle z is shared, wz=wz
Answer:
Side-angle-side postulate
Step-by-step explanation:
First, you know that angle XZW = YZW because they are both 90 degrees.
Next, you know that side WZ = side WZ because of the reflexive property (they are the same side)
Lastly, you know that YZ = XZ because Z is the midpoint meaning it divides the entire thing perfectly in half
You have two sides and the included angle, so it is SAS.
Help would be appreciated
Answer: Yes
Step-by-step explanation:
x = 3
y = -7
10x + 20y ≥ -3
10 (3) + 20 (-7) ≥ -3
30 + (-140) ≥ -3
30 - 140 ≥ -3
-110 ≥ -3

Write the equation of the line that passed through the point (-1,-4) that is perpendicular to the line
2
у -2 +1.
Show all of your work and answer in the text box provided.
Answer:
The line that meets these conditions is y = 1.5x - 2.5
If you want to use fractions, it would be y = 3x/2 - 5/2
Step-by-step explanation:
To get a line perpendicular to y = -(2/3)x + 1, We can start by finding its slope. That's easy enough as a perpendicular slope is the negative reciprocal of the given one. As this has a slope of -2/3, our new slope has to be 3/2, or 1.5
All we need to do then is express that rate of change relative to the given point (-1, -4). We can do this by expanding the classic equation:
Δy = sΔx
We can write that as such:
y - (-4) = 1.5(x - (-1))
y + 4 = 1.5(x + 1)
y + 4 = 1.5x + 1.5
y = 1.5x + 1.5 - 4
y = 1.5x - 2.5
Or if you want to express those numbers as fractions, it would be y = 3x/2 - 5/2.
To make sure the answer's correct, we can simply plug -1 in as the x value, and see if we get y = -4:
y = 3(-1) / 2 - 5/2
y = -3 / 2 - 5 / 2
y = -8 / 2
y = -4
So we know that our answer is correct (assuming that the slope is correct, which it is - a perpendicular line always has the negative reciprocal of the other line's slope).

PLS HELP I'll GIVE BRAINLIEST.... A student walks x kilometers (km) along a straight path from point P to point Q. Then the student walks y km along a straight path from point Q to point R. What is the total distance, x + y, in km, that the student walks?
Answer:
5.5 km
Step-by-step explanation:
P.S - The exact question is -
As from the figure , we can see that
2 square = 1 km
Now,
Number of squares between P and Q = 4
Number of square between Q and R = 7
So,
Total number of squares = Number of squares between P and Q + Number of squares between Q and R
= 4 + 7 = 11
⇒Total number of squares = 11
Now as
2 squares = 1 km
⇒ 1 square = [tex]\frac{1}{2} km[/tex]
⇒11 square = [tex]\frac{11}{2} km = 5.5 km[/tex]
∴ we get
total distance, x + y = 5.5 km
At an average internet speed of 15 mbps, a computer takes 4 minutes to
download an application file. If the speed slows down to 10 mbps, how
long does the computer take to download the file?
Answer:
6 minutes
Step-by-step explanation:
Speed of net = 15mbps
Time taken = 4min.
Total size of application= 15*60*4= 3600mb
Now speed = 10mbps
Time taken = 3600/10
= 360 sec = 360/6 min
= 6 min
