Answer:
C. [tex]\bold{a=8\frac8{15}}[/tex]Step-by-step explanation:
[tex]\frac54(a-8)=\frac23[/tex] multiply both sides by [tex]\frac45[/tex]
[tex]\frac45\cdot\frac54(a-8)=\frac23\cdot\frac45[/tex]
[tex]a-8=\frac8{15}[/tex] add 8 to both sides
[tex]a=8\frac8{15}[/tex]

HURRY What is the solution to the trigonometric inequality
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]

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

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.

C. 2x - 3y = 8
5x = 10
Answer:
C
Step-by-step explanation:
the x,y matrix will have the form of some x coefficient value, some y coefficient value and then the answer. if one of these values are missing you use a 0 as placeholder. look at the coefficients here. you know one equation will have an x coefficient of 2 and a y coefficient of -3 with a solution of 8 and the other equation will have x coefficient of 5 and no y at all with a solution of 10. only option c meets these criteria

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
