James purchased 2 T-shirts and a pair of jeans online and paid $80 for his purchase. The next week, the same site was offering a

Maurinko [17]

2t + j = 80
3(0.5)t + 2(0.5)j = 70

j = 80 - 2t
1.5t + j = 70
1.5t + 80 - 2t = 70
-0.5t = 70 - 80
-0.5t = -10
t = -10/-0.5
t = 20

j = 80 - 2t
j = 80 - 2(20)
j = 80 - 40
j = 40

so ur answer is C

2 sin x cos x = tan x

eimsori [14]

Answer:

If $sin x = 0$ we get $2 (0) (\pm1) = 0$ which is true. so we have a first set of solutions given by

$x= 0; x = \pi$ ;

Else, if $sin x \ne 0$ we can divide both sides by it and we get

$2 cos x = \frac 1 {cos x} \rightarrow 2cos^2x =1 \rightarrow cos^2x =\frac12\\cos x= \pm \frac{\sqrt2}2$

Which gives us a second set of solutions given by $x= \frac{\pi}4;x= \frac{3\pi}4; x= \frac{5\pi}4;x= \frac{7\pi}4$ ;

We can group all solutions (doesn't matter, but it's more elegant!) by writing

$x= k\frac{\pi}4; k\in \{0,1,3,4,5,7\}$

Use the table to determine slope and y intercept.

aleksklad [387]

Answer: The slope is 9/2 or 4.5

The y-intercept is 0

The equation of the line is y = 4.5x or $y =\frac{9}{2}x$

Step-by-step explanation: Using Slope intercept form, y = mx + b

m is the slope and b is the y-intercept.

Slope is rise/run.

The difference in y-values is 225. That is the rise

The difference in x values is 50, so that is the run.

225/50 can be simplified to 9/2 or 4.5

Use the calculated slope and any pair of values from the table to substitute for y and x in the equation and solve for b.

225 = 4.5(50) + b . Multiply mx

225 = 225 + b . Subtract 225 from both sides.

225-225 = b

0 = b

Rewrite the equation in slope-intercept form using the calculated values for m and b

When b is 0, it is omitted from the equation.

The resulting equation is

y = 4.5x or $y =\frac{9}{2}x$
