if a cell phone provider offers a plan that costs $20 per month plus $0.10 text messages sent or received a comparable plan costs $50 per month but offers unlimited text messaging how many text messages would have to be sent or received in order for the plans to cost the same each month
Answer: You would have to send 300 text messages
Step-by-step explanation:
1. Turn problem into 20 + 0.10x = 50
2. Subtract 20 from both sides to get 0.10x = 30
3. Divide both sides by 0.10 to get x = 300

As the slope is -2, so the rate of change of the function is:
rate of change of function = -2Step-by-step explanation:
The slope is basically the rate of change of a function.
Let us take the two points from the graph
(0, 5)(4, -3)Taking the slope between two points to determine the rate of change of a function
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:5\right),\:\left(x_2,\:y_2\right)=\left(4,\:-3\right)[/tex]
[tex]m=-2[/tex]
As the slope is -2, so the rate of change of the function is:
rate of change of function = -2ANSWER HERE! pleaseeee

Answer:
C(-2,-5).
Step-by-step explanation:
FOR A CLOCKWISE 270° ROTATION:
Given point A(x,y) its image is given
as A`(y,-x).
For the image of C which is C`(-5,2)
Comparing this to A`(y,-x)
y = -5 and -x = 2,x = -2
hence C compared to A(x,y)
will be C(-2,-5).
2x - 6y = - 24 and x + -5y = -22
by substitution
Answer:
2x-6y=-24
2x=-24+6y
x=-24+6y÷2
x=-12+3y equation 1
x+(-5y)=-22
-12+3y-5y=-22
-13-2y=-22
-2y=-22+13
-2y=-9
y=-9÷2
y=4.5equation 2
putting value of equation 2 in equation 1
x=-12+3y
x=-12+3×4.5
x=-12+13.5
x=1.5 answer!!!
Which choice is equivalent to the fraction below x>=3?
Answer:
Answer: D. 2(V[x} + V{x - 2}) Step-by-step explanation: As hinted in the question, we have to simplify the denominator. To understand it easier, let's imagine we have x - y in the denominator. If we multiply it with x + y we'll get x? - y, right? Check the next line: (x - y) (x + y) = x² + xy -xy - y? = x² - y? If we have the square of those nasty square roots, it will be much simpler to deal with. So, let's multiply the initial fraction using x+y, but with the real values: 4 x-2 x+Vx-2 x-2 4(Va+v-2) (V#)² -(væ–2)² Then we simplify: 4(va+væ-2) 4(Va+va-2) (Væ)2-(Va-2)2 2(Va + Va – 2) 4(va+va-2) (x) -(x-2) 2 Answer is D. 2(V{X} + v{x - 2})

Write the expression as the
sine or cosine of an angle.
Answer:
sine(pie/5+pie/2)
Step-by-step explanation:
The expression, written as the sine of an angle is sin (7π/10)
Trigonometry Identities
From the question, we are to write the given expression as the sine or cosine of an angle.
The given expression is
sin(π/5)cos(π/2) + sin(π/2)cos(π/5)
Let A = π/5
and
B = π/2
Thus, we get
sinA cosB + sinB cosA
From the given information, we have that
sin(A ± B) = sinA cos B ± cosA sinB
∴ sin(A + B) = sinA cos B + cosA sinB
Now,
sinA cosB + sinB cosA = sinA cosB + cosA sin B
∴ sinA cosB + sinB cosA = sin (A + B)
Put A = π/5
and
B = π/2
sinπ/5 cosπ/2 + sinπ/2 cosπ/5 = sin (π/5 + π/2)
sinπ/5 cosπ/2 + sinπ/2 cosπ/5 = sin (7π/10)
Hence, the expression, written as the sine of an angle is sin (7π/10)

domain: (-00,00) ; range: (–00,00) ix-intercept: (11,0) : v-intercept: (0, - 2)
[-4,11] :x-intercept: (11,0) : vintercept: (0, - )

C.
domain: (0, 11] : range:
D.
Given:
The function is
[tex]f(x)=7x+11[/tex]
To find:
The domain, range, and intercepts of the function.
Solution:
We have,
[tex]f(x)=7x+11[/tex]
It is a linear function, and domain and range of these types of functions are all real numbers.
[tex]Domain:(-\infty,\infty)[/tex]
[tex]Range:(-\infty,\infty)[/tex]
Put x=0 in f(x), to find the y-intercept.
[tex]f(0)=7(0)+11[/tex]
[tex]f(0)=0+11[/tex]
[tex]f(0)=11[/tex]
So, the y-intercept is 11.
Put f(x)=0 in f(x), to find the x-intercept.
[tex]0=7x+11[/tex]
[tex]0-11=7x[/tex]
[tex]-11=7x[/tex]
Divide both sides by 7.
[tex]\dfrac{-11}{7}=x[/tex]
So, the x-intercept is [tex]\dfrac{-11}{7}[/tex].
Therefore, [tex]Domain:(-\infty,\infty), Range:(-\infty,\infty), x-intercept : (\dfrac{-11}{7},0),[/tex] [tex]y-intercept :11[/tex].
The diagram shows a triangle.
19c+16°
13c
17c+17°
What is the value of c?
c =
°
Answer:
c=3
Step-by-step explanation:
Angle sum of a triangle is 180°
(19c+16)°+13c°+(17c+17)°=180°
collect the like terms i.e
19c+13c+17c+16+17=180°
49c°+33°=180°
49c°=180°-33°
49c°=147
dividing by 49 both sides
49c/49=147/49
c=3

SHOW WORK
Answer:
[tex] \huge{ \boxed{ \bold{ \tt{2 \sqrt{26}}} \: \: \text{units} } } [/tex]
♁ Question :Find the distance between ( 5 , -6 ) and ( 3 ,4 ).♁ Step by step explanation:Let the points be A and B. Now,
Let, A ( 5 , -6 ) ⇢ ( x₁ , y₁ )Let, B ( 3 , 4 ) ⇢ ( x₂ , y₂ )Use the distance formula to determine the distance between A ( 5 , -6 ) and B ( 3 , 4 ).
[tex] \boxed{ \underline{ \sf{distance = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } }}}[/tex]
Substitute the actual value of the points into the distance formula and then simplify.
[tex] \dashrightarrow{ \sf{ \sqrt{ {(3 - 5)}^{2} + {(4 - ( - 6))}^{2} } }}[/tex]
Remember : The positive and negative integer are always subtracted but posses the sign of the bigger integer.
[tex] \dashrightarrow{ \sf{ \sqrt{ {( - 2)}^{2} + {(4 - ( - 6))}^{2} } }}[/tex]
Remember : ( - ) × ( - ) = ( + )
[tex] \dashrightarrow{ \sf{ \sqrt{ {( - 2)}^{2} + {(4 + 6)}^{2} } }}[/tex]
Add the numbers : 4 and 6
[tex] \longrightarrow{ \sf{ \sqrt{ {( - 2)}^{2} + {(10)}^{2} } }}[/tex]
Evaluate the power
[tex] \longrightarrow{ \sf{ \sqrt{4 + 100}}} [/tex]
Add the numbers : 4 and 100
[tex] \dashrightarrow{ \sf{ \sqrt{104}}} [/tex]
[tex] \dashrightarrow{ \boxed{ \sf{2 \sqrt{26} }}}[/tex] units
Therefore , The distance between ( 5 , -6 ) and ( 3 , 4 ) is [tex] \sf{2 \sqrt{26}} [/tex] units .
And we're done!

What is the point-slope form of an equation for a line that passes through the point (5, –5) with the slope of 2?
Answer:
y + 5 = 2(x - 5)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 2 and (a, b) = (5, - 5) , thus
y - (- 5) = 2(x - 5) , that is
y + 5 = 2(x - 5)

Struggling to do my math work haha please help. Worth 14 points!!!
Answer:
C. y = -1/2 + 2
Step-by-step explanation:
First, we need to find the Slope.
Points: ( -4,4) and (8,-2)
Formula: m = y2 - y1/x2 - x1
m = y2 - y1/x2 - x1
m = -2 - 4/8 - (-4)
m = -6/8 + 4
m = -6/12
m = -1/2
Alright, now that we have the Slope, we can now use the Slope Form to find the Slope Intercept Form.
Point: (8,-2) (You may choose any points, but I would like to choose these for no reason)
Slope: -1/2
Formula: y - y1 = m(x - x1)
y - y1 = m(x - x1)
y - (-2) = -1/2(x - (8))
y + 2 = -1/2x + 4
y = -1/2 + 4 - 2
y = -1/2 + 2
The Slope Intercept Form is: y = -1/2 + 2
