Which compound inequality has no solution?
Oxs-2 and 2x >6
Oxs-1 and 5x s5
Oxs-1 and 3x >-3
Oxs-2 and 4x s-8
HURRY PLSS
Answer: The first option:
x ≤ -2 and 2x ≥ 6
Step-by-step explanation:
A compound inequality will have no solution if the inequalities are contradictory.
An example of this would be:
x > 3 and x < 1
There is no value of x that is at the same time larger than 3, and smaller than 1.
Now, let's analyze the options.
1) x ≤ -2 and 2x ≥ 6
This has no solution, because if x ≥ -2, the maximum value that x can take is x = -2
Replacing that in the other inequality we get:
2*(-2) > 6
-4 > 6
This is false, then this compound inequality has no solution.
2) x ≤ -1 and 5*x < 5
This ineqalty has infinite solutions, one can be x = -2
-2 ≤ -1 and 5*(-2) < 5
are both true.
3) x ≤ -1 and 3x ≥ -3
A solution for this can be x = -1
-1 ≤ -1 is true
3*(-1) ≥ -3
-3 ≥ -3 is true.
Then we have at least one solution here.
4) x ≤ -2 and 4x ≤ -8
Here we have infinite solutions, one can be x = -10
-10 ≤ - 2 is true
4*(-10) ≤ -8
-40 ≤ - 8 is also true.
Then the only option that has no solutions is the first one.

Line a passes through that point (-8,-7) and has a slope of 5/8. Choose the equation that best represents A
Answer:
y = 5/8 x -2
Step-by-step explanation:
Given that the slope of the line, m=5/8, which passes through the point (-8,-7).
Let the equation of the line be y=mx+c
where m is the slope of the line and c is a constant.
As m=5/8, so the equation of line become
y= 5/8x+c
As the line passes through the point (-8,-7), so putting y= -7 and x= -8, we have
-7 = 5/8(-8)+c
-7 = -5 + c
c= -7 + 5
c= -2
On putting the value of c, the equation of line become
y=5/8 x -2
Hence, the equation of the line is y = 5/8 x -2.
An electricity company estimates that Daryl will spend £600 on electricity next year.
An administration charge of 15% is added.
Daryl wants to pay in four equal instalments throughout the year,
How much should each payment be?
Answer:
Each payment should be £172.5
Step-by-step explanation:
Cost of electricity for next year = £600
Administration charge = 15%
Daryl wants to pay in four equal instalments throughout the year,
How much should each payment be?
First we need to find the total cost of bill by adding 15% of administration charge by finding 15% of 600
[tex]15\% \:of\: 600\\=\frac{15}{100}\times 600\\= 90[/tex]
So, 15% of 600 is 90
Now adding 90 into the electricity cost:
600+90
= 690
Now, the total cost of electricity bill is £690
Daryl wants to pay in four equal instalments.
So, divide 690 by 4
Each payment for instalments is: [tex]\frac{690}{4} = 172.5[/tex]
So, Each payment should be £172.5

Line 1 y= -5/2x
Line 2 y= -5/2x +8
Which statement about the graph of the line is true
Answer:
They have the same slope
Step-by-step explanation:
Given
[tex]y = -\frac{5}{2}x[/tex]
[tex]y = -\frac{5}{2}x + 8[/tex]
Required
Determine the true statement about both lines
An equation has a general format of:
[tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
By comparing this to the equations of both lines, we have that:
For line 1:
[tex]m = -\frac{5}{2}[/tex]
For line 2:
[tex]m = -\frac{5}{2}[/tex]
Compare the slopes of both lines, we have that:
[tex]m = m = -\frac{5}{2}[/tex]
Hence, we can conclude that both lines have the same slope

periodpointblankA cheetah can run a rare of 105,600 years per hour find the number of miles the cheetah could run at this rate in 5 minutes.
Answer:
360 yards per 5 minutes.
Step-by-step explanation:
A cheetah can ride up to 105,600 yards per hour.
An hour is equal to 60 km.
It can run up to 'x' miles per 5minutes.
So, 360 x 5/ 5
= 1800/5
= 360 yards per 5 minutes.

ABCD is a parallelogram.
Angle B and Angle C are adjacent (successive) angles.
Adjacent angles of a parallelogram are supplementary.
Therefore,

Q. no. 1 ) Find the value of x.
Here we can clearly see that ∠DCB and ∠ABC are co - interior angles . And we know that the sum of co interior angles is 180° .
[tex]\tt:\implies \angle DCB + \angle ABC = 180^{\circ} \\\\\tt:\implies (2x + 12)^{\circ} + 5x^{\circ}=180^{\circ} \\\\\tt:\implies 7x = (180 - 12 )^{\circ} \\\\\tt:\implies 7x = 168^{\circ} \\\\\tt:\implies x =\dfrac{168^{\circ}}{7} \\\\\underline{\boxed{\red{\tt\longmapsto x = 24^{\circ}}}}[/tex]

Q. no. 2 ) Determine the measure of < C .
Here we can see that <C = 2x + 12 ° . So ,
[tex]\tt:\implies \angle C = 2x + 12^{\circ} \\\\\tt:\implies \angle C = 2\times 24^{\circ} + 12^{\circ} \\\\\tt:\implies \angle C = 48^{\circ} + 12^{\circ} \\\\\underline{\boxed{\red{\tt\longmapsto \angle C = 60^{\circ}}}}[/tex]

3x 16
Answer:
sum of interior angle of a triangle is 180 degree
so,
3x +7 + 2x+7 +3x+6 = 180
8x + 20 = 180
8x = 180 - 20
8x = 160
x = 160/ 8
x = 20
May it will help you
Answer:
x = 20
Step-by-step explanation:
According to angle sum property of a triangle , sum of all the angles in a triangle is equal to 180°.
So,
[tex](3x + 7) + (2x + 7) + (3x + 6) = 180[/tex]
[tex] = > 8x + 20 = 180[/tex]
[tex] = > 8x = 180 - 20 = 160[/tex]
[tex] = > x = \frac{160}{8} = 20[/tex]

45 min = 45*1/60 hr = 3/4 hrDistance is:
d = speed*timed = 26/3*3/4 = 13/2 = 6 1/2 milesIs this the X factor method and how would you do it?
====================================
Work Shown:
4x^2 - 8x - 192
4(x^2 - 2x - 48)
4(x - 8)(x + 6)
We see that (x - 8) is one factor
To factor x^2-2x-48 into (x-8)(x+6), we need to find two numbers that
add to -2, andmultiply to -48Through trial and error you should find the two values are -8 and 6 since
-8 + 6 = -2-8*6 = -48-----------
Another approach is to use the quadratic formula to solve x^2-2x-48 = 0. You should find that the two roots are x = 8 and x = -6.
Those two roots lead to the equations x-8 = 0 and x+6 = 0.
Then use the zero product property to get (x-8)(x+6) = 0
This shows that x^2-2x-48 factors to (x-8)(x+6)
