Answer:
4v-6.3w+9.8
Step-by-step explanation:
If you distribute the negative sign (same as distributing -1), then you get -(-4v) + (-6.3w) - (-(9.8))
Basically it's switching the signs
Hope that helped :)
х+ 5y = 16
х+ Зу = 10
x=?
y=?
Answer:
x=1 y=3
Step-by-step explanation:
x+5y=16
x+3y=10
2y=6
y=3
x+15=16
x=1
verify
1+9=10
Answer:
x = 1 , y = 3
Step-by-step explanation:
x + 5y = 16 → (1)
x + 3y = 10 → (2)
Subtract (1) from (2) term by term to eliminate x
0 + 2y = 6
2y = 6 ( divide both sides by 2 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting into (1)
x + 5(3) = 16
x + 15 = 16 ( subtract 15 from both sides )
x = 1

Find cos O if sinO = sqrt2/2 is in the second quadrant
Answer:
D. [tex]-\frac{\sqrt{2} }{2}[/tex]
Step-by-step explanation:
So, on a regular coordinate plane, coordinates are written (x,y)
well, in trig, coordinates are written (cosθ, sinθ).
if sinθ=[tex]\frac{\sqrt{2} }{2}[/tex] in the second quadrant, then look for the "y-value" that says
if you don't have a unit circle to look at, then it helps to know that the fraction [tex]\frac{\sqrt{2} }{2}[/tex] is ONLY found with ITSELF OR THE NEGATIVE OF ITSELF. it is never paired with another number.
this means that this number will only be seen in the coordinates
[tex](\frac{\sqrt{2} }{2} ,\frac{\sqrt{2} }{2})\\(-\frac{\sqrt{2} }{2},\frac{\sqrt{2} }{2})\\(-\frac{\sqrt{2} }{2},-\frac{\sqrt{2} }{2})\\(\frac{\sqrt{2} }{2},-\frac{\sqrt{2} }{2})[/tex]
use this knowledge along with knowing the signs in each quadrant:
Q1: (+,+)
Q2: (–,+)

pls helpppppppppppppppp Which value of y makes the equation 12y−3=5 true?
y is equal to 2
y is equal to 1
y is equal to 2 thirds
y=13
Answer:
y = 2/3
Step-by-step explanation:
so 12y-3=5, add the 3 to the 5 to get 12y=8. Then divide the 12y by 12 and the 8 by 12. In so you geet y=2/3
Answer:
y is equal to 2 thirds (y = 2/3)
Step-by-step explanation:
12y − 3 = 5
Substitute the given options to see which one will provide a true statement:
If y = 2:
12y − 3 = 5
12(2) − 3 = 5
24 − 3 = 5
21 = 5 (False statement, so it's not the right answer).
If y = 1:
12(1) − 3 = 5
12− 3 = 5
9 = 5 (False statement).
If y = 2/3:
12(2/3) − 3 = 5
8 - 3 = 5
5 = 5 (True statement).
If y = 13:
12(13) − 3 = 5
156 - 3 = 5
153 = 5 (False statement).
Therefore, the correct answer is: y = 2/3.

Answer:
the first option if you are looking for where they intercept
Step-by-step explanation:
Find two numbers if their ratio is 9:11 and their difference is 6 THERE ARE TWO ANSWERS!!
Step-by-step explanation:
x, y are the 2 numbers.
x/y = 9/11
x - y = 6
x = y + 6
now we use that in the first equation
(y + 6)/y = 9/11
y + 6 = 9y/11
11y + 66 = 9y
2y = -66
y = -33
x = y + 6 = -27
but the second equation could also be
y - x = 6
then
x = y - 6
and that in the first equation leads to
(y - 6)/y = 9/11
y - 6 = 9y/11
11y - 66 = 9y
2y = 66
y = 33
x = y - 6 = 27

Answer:
I don't know if you have given the full question.
Step-by-step explanation:
but from what you have typed I understood that ( -x ) = - ( x)
positive × positive = positive
negative × negative = positive
positive × negative = negative
so from this we derive -x = -x ( when we open the bracket negative 1 is multiplied to x)

To get to the camp in time, tourists had to go with a speed 4km/h. They went with that speed half of the road, but then they drove with a bus and arrived to the camp 2h 20min before the planned time. How many kilometers did tourists drive with the bus, if the speed of the bus was 60km/h?
Answer:
it is solved at jemrare dot com
Step-by-step explanation:
This problem can be solved using distance formula;
s=vt
Here we suppose;
Speed of Tourists=v1=4 km/h
speed of bus=v2=60km/h
Total time to be taken by the tourists to reach the camp without bus=t
Time taken by tourists when bus used=t-2h20min=t-140min
let the total distance is ‘x’ but half is travelled without bus and other half by bus!
for first half distance=s1 =x/2
for second half distance=s2=x/2
Using s=vt formula for first half;

6) Identify the graphed linear equation. A) y = 2 5 x - 5 B) y = 1 5 x - 5 C) y = 2 5 x + 5 D) y = 1 5 x + 5
Answer: There is no graph that I can see. I created one showing each line.
Step-by-step explanation: A straight line has the form y=mx+b, where m is the slope and b is the y-intercept (the value of y when x is zero). The two lines with slope 25 will rise much more quickly than the ones with a slope of 5. You could eliminate two lines based on that alone. With the two remaining lines, look at the y-intercept seen on the graph (the value of y when x=0). The options are 5 and -5. The correct line will be the one with the expected intercept.
12/x=45
What would x equal
Answer:
=4/15
=0.26
Step-by-step explanation:
Answer:
x = 4/15
Step-by-step explanation:
Step 1: Multiply both sides by x.
[tex]\frac{12}{x} * x = 45 * x[/tex] [tex]12 = 45x[/tex] [tex]45x = 12[/tex]Step 2: Divide both sides by 45.
[tex]\frac{45x}{45} = \frac{12}{45}[/tex] [tex]x = \frac{4}{15}[/tex]Therefore, x = 4/15.

Answer:
Slope = 3/2, or 1.5
Step-by-step explanation:
Pick out the lattice points ( points that intersect the graph markings)
I see 2 points, ( 3, 1), and ( 5, 4)
Slope = Δy/xΔ = 4 - 1/5 - 3 = 3/2
Slope is 3/2, or 1.5

Don't remember how to do this. Please help!
Step-by-step explanation:
Given the linear function, w(x) = 3/5x + 2, where the slope, m = 3/5, and the y-intercept is (0, 2).
Start by plotting the y-intercept on the graph. Then, use your slope, m = 3/5 (rise 3 units, run 5 units) to plot other points on the graph.
Attached is an edited screenshot of your given problem, which shows the plotted points on the graph using the techniques explained in this post.

Answer:
C
Step-by-step explanation:
24.75+(-24.75)= 0
Though I would have believed A would be correct if not for the fact of how far he walked which would be 4.6 miles
B is similar you can't become the same age as someone if the are older than you
D is just 230+230=460
