Match the solution set given in inequality notation with the solution set given in interval motion x > 7.8
Answer:
(7.8, ∞)
Step-by-step explanation:
Given the inequality :
x > 7.8 ; the inequality can be explicitly interpreted as x greater than 8 ; this means that the inequality holds for all values of x above 7.8
The interval for which the inequality holds true is :
x > 7. 8 - - - > (7.8, ∞)

what is the equation, in point-slope form, of the ljne that is perpendicular to the given line and passes through the point (-4,-3)?
Answer:y+3=1/4(x+4)
Step-by-step explanation:
First find the slope of the line with the points -1,1 and 0,-3
1-(-3)/-1-0 = -4
perpendicular is negative reciprocal which is 1/4
now we have the slope, and a point so we can put it in point slope form
y+3=1/4(x+4)
point slope form is y-y1 = m(x-x1)
with x1,y1 being the point and m being the slope

Answers:
number of sides = 15regular polygon name = regular 15-gon=======================================================
Explanation:
If 156 degrees is the interior angle measure, then 180-156 = 24 is the exterior angle measure.
Divide 360 over this to find that 360/24 = 15
This means the regular polygon has 15 sides.
I'm using the idea that if n is the number of sides, then 360/n is the exterior angle measure. So 180 - (360/n) is the interior measure.

given h (x)=5x-3 find the value of h(-4)
Answer:
h(- 4) = - 23
Step-by-step explanation:
To evaluate h(- 4) substitute x = - 4 into h(x) , that is
h(- 4) = 5(- 4) - 3 = - 20 - 3 = - 23
h (-3) = 57

solve this linear equation into every single step you would use -x+9+3x=4x+2(x-3.5)
Answer:
[tex]x=8[/tex]
Step-by-step explanation:
[tex]x+9+3x=4x+2(x-3.5)[/tex]
Distribute 2 to the parenthesis
[tex]x+9+3x=4x+2x-7[/tex]
Combine like terms
[tex]4x+9=6x-7[/tex]
Subtract 4x from both sides
[tex]4x+9=6x+-7[/tex]
[tex]-4x[/tex] [tex]-4x[/tex]
[tex]9=2x+-7[/tex]
[tex]2x+-7=9[/tex]
Add 7 to both sides
[tex]2x+-7=9[/tex]
[tex]+7[/tex] [tex]+7[/tex]
[tex]2x=16[/tex]
Divide both sides by 2
[tex]2x=16[/tex]
[tex]/2[/tex] [tex]/2[/tex]
[tex]x=8[/tex]

Find the volume of a regular square pyramid with base edge 10 ft. and height 12 ft.
120 ft
75ft?
400 ft
D 300 ft?
Answer:
V = 400 ft^3
Step-by-step explanation:
The area of the base of this regular square pyramid is (10 ft)^2, or 100 ft^2.
Recalling that the area of a pyramid is V = (1/3)(base area)(height), in this case we get V = (1/3)(100 ft^2)(12 ft) = 400 ft^3

Find the volume of the cube, if one face of the cube has an area of
121 sq.m.
Answer:
1331 m^2
Step-by-step explanation:
To find the volume of the cube, we should first find the length of one side's edge. The square root of 121 (the face area) gives us our edge length, 11.
Now, to find the volume of the whole cube, we use the equation V=11^3, and our result is 1331.

A pencil case with a cylinder shape with diameter= 10 cm
and height = 12 cm .
What is the length of the longest pencil that can fit in the pencil case?
Answer:
length of the longest pencil that can fit must be less than 13cm
Step-by-step explanation:
To get the longest pencil that fit the case, we will use the pythagoras theorem;
diameter = 10cm
radius = 10/2
radius = 5cm
Height = 12cm
Get the length of the longest side
l² = r²+h²
l² = 5²+12²
l² = 25 + 144
l² = 169
l = √169
l = 13cm
Hence the length of the longest pencil that can fit must be less than 13cm

Montraie is driving on a long road trip. He currently has 13 gallons of gas in his car.
Each hour that he drives, his car uses up 1 gallon of gas. How much gas would be in
the tank after driving for 6 hours? How much gas would be left after t hours?
Answer:
7 gallons
Step-by-step explanation:
Montraie is driving on a long road trip
He currentlyhase 13 gallons of fuel in his car
Each hour that he drives, he uses up 1 gallon of fuel
Therefore the amount of gas that would be left after 6 hours can be calculated as follows
= 13-6
= 7
Hence there will be 7 gallons of fuel left

whoch expression is equivalent to -20 - (-4)
Answer:
D
Step-by-step explanation:
-(-4)=+4
so it is -20+4
Answer:
D) -20 + 4 is the answer.
Step-by-step explanation:
1) Record the terms .
[tex]4 - 20[/tex]
2) Use this rule: a - b = -(b - a)
[tex] - (20 - 4)[/tex]
3) Use algorithm method.
(see the attached picture)
4) After simplifying, we have:
[tex] -(20 - 4) = - 16[/tex]

Part A: Estindlate the solution from the graph. -
Part B: What is the equation of each line in the system? blue line: _ and red line:
Answer:
Part A
The estimated solution of the graph is (37/29, -30/29)
Part B
The equation of the blue line is y = 0.6·x - 1.8
The equation of the red line is y = (-4/3)·x + 2/3
Step-by-step explanation:
Part A
From the given graph, we have two lines, one red and one blue line, intersecting in Quadrant IV
Given that the equation of the lines are also required, we find the solution of the graph, through the equation of the lines as follows;
The points through which the blue line passes are (-2, -3), and (3, 0)
The slope of the blue line, [tex]m_b[/tex] = (0 - (-3))/(3 - (-2)) = 0.6
Therefore, we have;
y - 0 = 0.6·(x - 3)
∴ The equation of the blue line is y = 0.6·x - 1.8
The approximate points through which the red line passes are (-1, 2) and (-2.5, 4)
The slope of the red line, [tex]m_r[/tex] = (4 - 2)/((-2.5) - (-1)) = -4/3
Therefore, we have;
y - 2 = (-4/3)·(x - (-1)) = (-4/3)·x - 4/3
∴ The equation of the red line is y = (-4/3)·x - 4/3 + 2 = (-4/3)·x + 2/3
y = (-4/3)·x + 2/3
The solution for the graph is the point where the y-values are equal
Therefore, wat the solution point, y = y, and 0.6·x - 1.8 = (-4/3)·x + 2/3
0.6·x + 4/3·x = 1.8 + 2/3
x = (1.8 + 2/3)/(0.6 + (4/3)) = 37/29 ≈ 1.28
At the solution of the graph, y = 0.6 × (37/29) - 1.8 = -30/29
Therefore, the estimated solution of the graph is (37/29, -30/29)
Part B
From the above solution of the graph, we have;
The equation of the blue line: y = 0.6·x - 1.8
The equation of the red line: y = (-4/3)·x + 2/3
if a/4=2/3, then (a-4)/4 would equal
a. -2/3
b. -1/3
c. 0
d. 1/3
Answer:
b. -1/3
Step-by-step explanation:
a/4=2/3
a=8/3
(a-4)/4
(8-12)/12
=-4/12
=-1/3
Answer:
-1/3
Step-by-step explanation:
a/4=2/3
Multiply each side by 4
a/4 *4=2/3 *4
a = 8/3
(a-4)/4
(8/3 - 4) /4
Getting a common denominator
(8/4 - 12/3) /4
(-4/3)/4
-1/3
