Answer:

=4/15

=0.26

Step-by-step explanation:

Answer:

x = 4/15

Step-by-step explanation:

Step 1: Multiply both sides by x.

Step 2: Divide both sides by 45.

Therefore, x = 4/15.

Answer: y = -x1 - 1

Step-by-step explanation:

Do both points satisfy this equation?:

(1,-2): -2 = -1 -1 Yes

(-3,2): 2 = -(-3)-1 [or 3-1=2] Yes

The line contains the points (1,-2) and (-3,2) is Y= -x-1. The correct option is B.

A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that the points are  (1,-2) and (-3,2). The equation of the line will be the line which satisfies the given points.

Y= -x-1

At points (1,-2),

Y= -x-1

-2=-1-2

-2=-2

At point(-3,2).

Y =-x-1

2=3-1

2 = 2

The line Y= -x-1 is passing through the points  (1,-2) and (-3,2). The correct option is B.

Answer:

15 seconds

Step-by-step explanation:

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.

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;

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

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:

Answer:

the first option if you are looking for where they intercept

Step-by-step explanation:

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.

Answer:

1,295

Step-by-step explanation:

35 - 100%

x - 3,7%

x= 35*3,7:100=1,295

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
