Does the system shown always, sometimes, or never have a solution when a > b?
ax + y = 8
bx + y = 5
Answer:
always have a solution
Step-by-step explanation:
A linear equation in standard form is given by:
Ax + By = C, where A,B, C are real numbers and A,B is not equal to zero.
Two linear equations with equations Ax + By = C and Dx + Ey = F
Therefore the first equation becomes: (A/B)x + y = C/B and the second equation becomes (D/E)x + y = F/E ]
Both equations are said have a solution if A/B ≠ D/E, they have no solution if A/B = D/E and they have infinite solutions if A/B = D/E, C/B = F/E.
Given that:
when a > b
ax + y = 8
bx + y = 5
Since a ≠ b, but a > b, the system has a solution

5. A pizzeria charges $8 for a large cheese pizza,
plus $2 for each topping. The total cost for a large
pizza is given by the equation C = 2t + 8, where t is
the number of toppings. Graph the equation for
t between 0 and 5 toppings, and explain the meaning
of the slope and y-intercept.
Answer:
Step-by-step explanation:
The total cost for a large pizza is given by the equation:
C=2t+8
where t is the number of toppings.
Now, when t=0 we have:
C=8
when t=1 we have:
C=10
when t=2 we have:
C=12
when t=3 we have:
C=14
when t=4 we have:
C=16
when t=5 we have:
C=18
i.e. the graph of this equation is the ordered pair:
(0,8) , (1,10) , (2,12) , (3,14) , (4,16) and (5,18)
Now, the slope of this function means the cost of each topping.
and the y-intercept represents the cost of the pizza when there are no toppings.

=========================================================
Explanation:
We have two smaller right triangles that are glued together so to speak.
The base of the smaller triangle on the left is 5 while the height is h.
Let's use the tangent rule to find the value of h
tan(angle) = opposite/adjacent
tan(55) = h/5
5*tan(55) = h
h = 5*tan(55)
h = 7.14074003371058
Make sure your calculator is in degree mode. That value of h above is approximate.
--------------------------
Now focus on the smaller triangle on the right
It has the same height value h. This side is the adjacent side while x is the hypotenuse.
We'll use the cosine ratio
cos(angle) = adjacent/hypotenuse
cos(42) = h/x
cos(42) = 7.14074003371058/x
x*cos(42) = 7.14074003371058
x = 7.14074003371058/cos(42)
x = 9.6088135029715
x = 9.6

Randall is saving money to buy a bicycle. He has 37.80 in his savings account and saves 20% of his paper route earnings each week. After 10 weeks, he has $87.80 in his savings account. How much does Randall earn each week from his paper route
in 10 weeks he saved: 87.8-37.8= $50
so each week he saves 50/10= $5
So every week he earns 5*100 / 20= $25

The value of angle [tex]x[/tex] will be [tex]70^0[/tex] .
What is triangle ?A triangle is a polygon with three edges and three vertices. Its angles sum property says that the sum of all angles of a triangle is equals to [tex]180^0[/tex] . i.e.
[tex]\angle A + \angle B + \angle C = 180^0[/tex]
We have,
[tex]\triangle ABC[/tex], in which,
[tex]\angle A =50^0[/tex]
[tex]\angle C =x^0[/tex]
Let, [tex]\angle B =y^0[/tex]
Now,
Work out for [tex]\angle B[/tex],
A straight line always makes an angle of [tex]180^0[/tex] i.e. line [tex]CBD[/tex], which is divided into parts at [tex]B[/tex] by [tex]AB[/tex],
So,
[tex]120^0 + y =180^0[/tex]
[tex]y=180-120[/tex]
[tex]y=60^0[/tex]
Now,
Using angle sum property;
[tex]\angle A + \angle B + \angle C = 180^0[/tex]
[tex]50^0+60^0+x=180^0[/tex]
⇒ [tex]x=180-110[/tex]
[tex]x=70^0[/tex]
Hence, we can say that the measure of [tex]x[/tex] in the triangle will be [tex]70^0[/tex] .

2sin(x)+3> sin^2(x) over the interval 0<=x<=2pi radians?
Answer:
C on edge 2021
Step-by-step explanation:
The solution of x for the trigonometric inequality [tex]2sin(x)+3 > sin^2(x)[/tex] is x will lie between 0≤x< [tex]\frac{3\pi}{2}[/tex]
What is trigonometric inequality?An inequality of the standard form R(x) > 0 (or < 0) that consists of 1 or a few trigonometric functions of the variable arc x is a trigonometric inequality. Finding a solution to the inequality means determining the values of the variable arc x whose trigonometric functions make the inequality true.
According to the question
The trigonometric inequality :
[tex]2sin(x)+3 > sin^2(x)[/tex] and the interval 0<=x<=2pi radians
Let sin(x) = t
Now, inequality is :
[tex]2t+3 > t^{2}[/tex]
0 > t² - 2t - 3
0> t² - (3-1)t - 3
0> t² - 3t + t - 3
0> t( t - 3) + 1(t - 3)
0> ( t - 3) (t+1)
t < -1 or t < 3
sin(x) < -1 or sin(x) < 3
as sin(x) can not be 3 because sin oscillates between 1 and -1. Sine will never result in 3 so we disregard this as a solution.
sin(x) < -1
sin(x) < sin ([tex]\frac{3\pi}{2}[/tex] )
x < [tex]\frac{3\pi}{2}[/tex]
And the given interval for x
0<=x<=2pi radians
Therefore,
x will lie between
0≤x< [tex]\frac{3\pi}{2}[/tex]
Hence, The solution of x for the trigonometric inequality [tex]2sin(x)+3 > sin^2(x)[/tex] is x will lie between 0≤x< [tex]\frac{3\pi}{2}[/tex]

-5-5(6x-8)=-5x+19
Answer:
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−5−5(6x−8)=−5x+19
−5+(−5)(6x)+(−5)(−8)=−5x+19(Distribute)
−5+−30x+40=−5x+19
(−30x)+(−5+40)=−5x+19(Combine Like Terms)
−30x+35=−5x+19
−30x+35=−5x+19
Step 2: Add 5x to both sides.
−30x+35+5x=−5x+19+5x
−25x+35=19
Step 3: Subtract 35 from both sides.
−25x+35−35=19−35
−25x=−16
Step 4: Divide both sides by -25.

What is Algebra?Algebra, a discipline of mathematics where abstract symbols rather than concrete numbers are subjected to arithmetic operations
As per the given data:
We are given an expression, and we have to find out the value of x by solving the given expression.
-5 - 5(6x-8) = -5x + 19
In LHS, multiplying by 5 in the whole bracket.
-5 - [5 × 6x - 5 × 8] = -5x + 19
-5 - [30x - 40] = -5x + 19
In LHS, multiplying by -ve in the bracket.
-5 - 30x + 40 = -5x + 19
Adding 5x both the sides.
-5 - 25x + 40 = 19
Taking all the constants to the RHS after switching signs.
-25x = 19 - 40 + 5
-25x = -16
Multiplying by -ve both the sides.
25x = 16
x = 16/25
The value of x is 16/25.
Hence, The value of x is 16/25.
