Answer:
here!<3
Step-by-step explanation:
A: 9 + 13 + 10 is equal to or less than C
B: 32 is equal to or less than C
Step-by-step explanation:
How I got A:
in order to solve this you have to add 9, 13, and 10.
don't solve it right away, but write every number out individually.
It says in the problem, "Afterward he had AT MOST $10".
With this we know we need a sign other than equal to.
if the amount was at most $10, we need to use equal to or less than.
I chose equal to or less than because it says AT MOST, so the amount he was pain will be equal to, or less than all of then numbers given to us added.
How I got B:
I added 9, 13, and 10.
The sum of these numbers is 32
C is our variable, because we don't know how much they paid him
32 is equal to or less than C
Hope this helps <3
solve the systems of equations via graphing then check the solution in each equation: 4x+6y=18, (y+2)=1/3(x+2)
Answer:
(4 1/3, 1/9)Step-by-step explanation:
Given system
4x + 6y = 18(y + 2) = 1/3(x + 2)Solution is the intersection point:
(4 1/3, 1/9)Simplify the first equation:
2x + 3y = 93y = -2x + 9y = -2/3x + 3Check:
1/9 = -2/3*4 1/3 + 91/9 = -26/9 + 91/9 = (27 - 26)/91/9 = 1/9Simplify the second equation:
y + 2 = 1/3x + 2/3y = 1/3x + 2/3 - 2y = 1/3x - 4/3Check:
1/9 = 1/3*13/3 - 4/31/9 = (13 - 12)/91/9 = 1/9Answer:
see belowStep-by-step explanation:
to understand thisyou need to know about:linear equationgraphing linear equationPEMDASgiven equation:4x+6y=18......(I)
(y+2)=1/3(x+2).......(ii)
let's solve using graph:the picture is attached
got from the picture
[tex]x = 4 \frac{1}{3} \\ y = \frac{1}{9} [/tex]
let's justify the (I) equation
[tex]4(4 \frac{1}{3}) + 6( \frac{1}{9} ) = 18[/tex]
[tex]4( \frac{13}{3} ) +6 (\frac{1}{9}) = 18[/tex]
[tex] \frac{52}{3} + \frac{2}{3} = 18[/tex]
[tex] \frac{52 + 2}{3} = 18[/tex]
[tex] \frac{54}{3} = 18[/tex]
[tex]18 = 18[/tex]
provenlet's justify the ii equation:[tex] \frac{1}{9} + 2 = \frac{1}{3} ( \frac{13}{3} + 2)[/tex]
[tex] \frac{19}{9} = \frac{1}{3} \times \frac{19}{3} [/tex]
[tex] \frac{19}{9} = \frac{19}{9} [/tex]
provenA tractor, starting from a stationary position, drives down the road. It accelerates at 4 m/s2 for 10 seconds, then travels at a steady pace for another 30 seconds. How much distance has it covered since it started driving?
A. 1,550 m
B. 1,400 m
C. 200 m
D. 1,200 m
Answer:
B. 1400 meters.
Step-by-step explanation:
According to the statement, there are two stages for the motion of the tractor, in which we need to find the travelled distance:
(i) Uniform accelerated motion.
[tex]s_{i} = s_{o,i} +v_{o,i}\cdot t_{i} + \frac{1}{2}\cdot a\cdot t_{i}^{2}[/tex] (1)
[tex]v_{i} = v_{o,i}+a\cdot t_{i}[/tex] (2)
Where:
[tex]s_{o,i}[/tex] - Initial position of the tractor, measured in meters.
[tex]s_{i}[/tex] - Final position of the tractor, measured in meters.
[tex]v_{o,i}[/tex] - Initial velocity of the tractor, measured in meters per second.
[tex]t_{i}[/tex] - Time, measured in seconds.
[tex]a[/tex] - Acceleration, measured in meters per square second.
[tex]v_{i}[/tex] - Final velocity of the tractor, measured in meters per second.
(ii) Uniform motion.
[tex]s_{ii} = s_{i} + v_{i}\cdot t_{ii}[/tex] (3)
Where:
[tex]s_{ii}[/tex] - Final position of the tractor, measured in meters.
[tex]t_{ii}[/tex] - Time, measured in seconds.
The distance covered by the tractor ([tex]\Delta s[/tex]), measured in meters, is:
[tex]\Delta s = s_{ii}[/tex] (4)
If we know that [tex]a = 4\,\frac{m}{s^{2}}[/tex], [tex]t_{i} = 10\,s[/tex], [tex]v_{o,i} = 0\,\frac{m}{s}[/tex], [tex]s_{o,i} = 0\,m[/tex] and [tex]t_{ii} = 30\,s[/tex], then distance covered by the tractor is:
By (1) and (2):
[tex]s_{i} = 0\,m + \left(0\,\frac{m}{s} \right)\cdot (10\,s)+ \frac{1}{2}\cdot \left(4\,\frac{m}{s^{2}} \right) \cdot (10\,s)^{2}[/tex]
[tex]s_{i} = 200\,m[/tex]
[tex]v_{i} = \left(0\,\frac{m}{s} \right)+\left(4\,\frac{m}{s^{2}} \right)\cdot (10\,s)[/tex]
[tex]v_{i} = 40\,\frac{m}{s}[/tex]
By (3):
[tex]s_{ii} = 200\,m + \left(40\,\frac{m}{s} \right)\cdot (30\,s)[/tex]
[tex]s_{ii} = 1400\,m[/tex]
By (4):
[tex]\Delta s = 1400\,m[/tex]

Jelani has twice as much money on his subway pass as Alexis. If they both add $20 to their passes, Jelani will have 1.5 times as much on his pass as Alexis. Write an equation to represent this situation.
Answer:
since J=2A
2A+20=1.5(A+20)
Step-by-step explanation:
J=2A
2A+20=1.5(A+20)
simplified for proof
J+20=1.5A+30
.5A=10
A=20
J=40
Equation for situation is x - 1.5y = 10, where x is the money of Jelani and y is money of Alexis.
What are linear equations?An algebraic equation with a variable with a highest exponent of one is known as a linear equation. Some linear systems have three equations, but not all linear equations have one, two, or three variables. Generally, an arrangement of straight condition has just a solitary arrangement yet at times, it has no arrangement or boundless number of arrangements.
Given Jelani has twice the money as Alexis,
let Jelani have money be x and Alexis have money be y
according to question x = 2y
and if both add $20 dollar to their pass Jelani will have 1.5 times much than Alexis, so x + 20 = 1.5(y + 20)
simplify x - 1.5y = 10
Hence the equation will be x - 1.5y = 10

0.35
0.44
0.52
Answer:
0.44
Step-by-step explanation:
Using it's concept, it is found that the experimental probability of an even number other than 8 being generated is of 0.44.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, out of 300 numbers, 154 are even, 22 are eight, hence 132 are even numbers different of eight, hence the probability is given by:
p = 132/300 = 0.44.

Answer:
y = -2/3x - 1
Step-by-step explanation:
First, find the slope so you can see that when x goes up by 3, y goes down by 2. This means that the slope is -2 divided by 3, or -2/3.
You can see in the picture that the y-intercept is at the point (0, -1).
That means the equation would be y = -2/3x - 1
Write the equation of a line that would be parallel to the line given.
