Choose the missing step in the given solution to the inequality −2x − 14 > −4 + 3x.
−2x − 14 > −4 + 3x
−5x − 14 > −4
_____________
x < −2
A. −5x < 10
B. −5x > −18
C. −5x > 18
D. −5x > 10
Answer:
Step-by-step explanation:
-2x - 14 > -4 + 3x
subtract 3x from both sides
-5x - 14 > -4
add 14 to both sides
-5x > 10
divide both sides by -5
x < -2
The answer would be -5x > 10.
This is because our last inequality was -5x - 14 > -4 so we add 14 to both sides and it would look like this -5x (-14 + 14) > (-4 + 14) which would transition into our next inequality -5x > 10.
So therefore the answer would be -5x > 10.
pls help me !! will mark brainliest... i just need you to solve for m<1 and m<7 !! thanks !!
Step-by-step explanation:
=( n-2)180
= ( 4 - 2 )180
= 360
So, 144 + 90 + m<2 +m<1 = 360
144 + 90 + 85 + m<1 = 360
319 + m<1 = 360
m<1 = 360 - 319
m<1 = 41
their is an unknown angle so let's call it x
let's find x first ( m<6=49)
x + m<6 = 180
x + 49 = 180
x = 180 - 49
x = 131
Now let's find m<7
m<7 + 38 + m<4 + x = 360
m<7 + 38 + 85 + 131 = 360
m<7 + 254 = 360
m<7 = 360 - 254
m< 7 = 106

Answer:
1. 144 2. 16 3. 1 4. 3x-6
Step-by-step explanation:
So think of this as a function in a function. So you work from the inside to the outside. So for problem 1, we start with f(4)) [you read it "f of 4"] so what is the solution when x = 4, since f(x) means the function of x so f(4) means 'the function of 4' inside f(x).
Since f(x) = 3x then f(4) = 3(4) [notice how you substitute the 4 everywhere you see a letter x]
so f(4) = 12, now you work the next part h(f(4)) since f(4)=12 then h(12)
So take the h(x) function which is h(x) = [tex]x^{2}[/tex] then h(12) = [tex]12^{2}[/tex] so h(12) = 144
Help !! Asap!! Please
Answer:
4
Step-by-step explanation:
so 8*6=48, so we know that (4*6)+(_*6) should equal 48.
4*6=24
subtract 24 by 48 and we get 24.
now you probably know that it equals 4, but to be sure, divide 24 by 6, and you'll get 4.
Answer:
From top to bottom:
1st box: 4
2nd box: 24
3rd box: 48
Step-by-step explanation:
So, based on my knowledge, you are learning the Distributive probability. So, what the Distributive property does is it basically allows to distribute the one of the numbers in the multiplication problem. In this problem, we can see that the 8 is being distributed into two groups of 4 to make (4 * 6) + (4 * 6). Then, we solve the things in the two parenthesis, making 24 + 24. Now, all we have to do is add 24 + 24, making 48.

Given the measure of two of the angles, find the measure of the 3rd
Answer:
Measure of 3rd angle is 80 degrees
angle SAX - angle PAX = measure of 3rd angle (SAP)
hence 141 - 61 = 80 degrees
hence measure of 3rd angle is 80 degrees

A line that includes the point (6,-4) has a slope of -1/2 what’s the equation in slope intercept form
Answer:
The equation in the slope-intercept form will be:
[tex]\:y=-\frac{x}{2}-1[/tex]Step-by-step explanation:
Given
Point (6, -4)Slope m = -1/2Important Tip:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
[tex]m[/tex] represents the slope[tex]b[/tex] is the y-interceptIn our case,
(x, y) = (6, -4)m = -1/2Step 1 of 2
Determine the y-intercept b
substitute m = -1/2 and (x, y) = (6, -4) in the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
[tex]-4\:=-\:\frac{1}{2}\left(6\right)+b[/tex]
switch sides
[tex]-\frac{1}{2}\left(6\right)+b=-4[/tex]
[tex]-3+b=-4[/tex]
Add 3 to both sides
[tex]-3+b+3=-4+3[/tex]
simplify
[tex]b=-1[/tex]
Thus, the y-intercept b = -1
Step 2 of 2
substitute the values
substitute b = -1 and m = 1/2 in the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
[tex]y=-\frac{1}{2}x+\left(-1\right)[/tex]
[tex]\:y=-\frac{x}{2}-1[/tex]
Conclusion:
Therefore, the equation in the slope-intercept form will be:
[tex]\:y=-\frac{x}{2}-1[/tex]
The graph of the line equation is also attached.

a) 25.8
b) 36.8
c) 64.2
d) 42.0
Answer:
y = 25.8
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos y = adjacent/ hypotenuse
cos y = 18/20
Take the inverse cos of each side
cos ^-1 (cos y) = cos^-1(18/20)
y =25.84193276
Rounding to the nearest tenth
y = 25.8

The semi-circle has a diameter of 8. What is the perimeter of the semi-circle?
Answer:
roughly 12.56 units
Step-by-step explanation:
Since the perimeter of a circle is 2*pi*r, we can divide it by two or multiply by half in order to find the perimeter of a semicircle
half of the diameter is the radius, so 8/2 =4, r=4
Plug in what we know...
C=2*pi*4
Solve
2*3.14*4
25.12
divide by 2
25.12/2=12.56
12.56 units is the perimeter
Answer:
Approx. 20.566 units
Step-by-step explanation:
Find the circumference of the whole circle first by doing:
C = 2πr
r = 4 (8 divided by 2)
C ≈ 25.133
Then divide that by two because a semi-circle is half a circle:
12.566
Then add 8 (diameter) to that number for the open side.
Hope this helps :)
Verify Euler's formula for
(a) Tetrahedron
(b) Hexagonal prism
Answer:
Euler's formula for polyhedron is:
V - E + F = 2where V- vertex, E- edge, F- faceAs per the above formula the relationship between the vertexes, edges and faces is same for any polyhedron.
Lets confirm, have a look at the picture
(a) Tetrahedron, count each element:
V = 5, E = 8, F = 5Verify
5 - 8 + 5 = 10 - 8 = 2 - correct(b) Hexagonal prism, count each element:
V = 12, E = 18, F = 8Verify
12 - 18 + 8 = 20 - 18 = 2 - correct$77 at 16% for 6 months
What is the difference between the total amount in the account if you did simple and compound interest?
Answer:
$0.231
Step-by-step explanation:
Given data
P= $77
r= 16%
t= 6 months= 0.5 years
For simple interest
A= P(1+rt)
A=77(1+0.16*0.5)
A= 77(1+0.08)
A= 77*1.08
A= $83.16
For compound interest
A=P(1+r)^t
A= 77(1+0.16)^0.5
A= 77(1.16)^0.5
A= 77*1.077
A= $82.929
The difference is
=83.16- 82.929
=$0.231
