Answer:

<h2>6x = 16</h2>

Step-by-step explanation:

6:2=8:x\to\dfrac{6}{2}=\dfrac{8}{x}\qquad\text{cross multiply both sides}\\\\(6)(x)=(2)(8)\\\\6x=16

Mark had 14 problems wrong on his test. his score was 72% correct. how many problems were on the test?
ella [17]
Let x = number of problems on test
If he got 14 wrong, then x - 14 is the number correct.
\frac{x-14}{x} = .72&#10;
x - 14 = .72x
.28x - 14 = 0
.28x = 14
x = 50

The test consisted of 50 problems.

I need help with this problem <br><br> Someone explain this to me
Anton [14]

Answer:

16.5

Step-by-step explanation:

Look at the relation between the 2 sides that you have measurements for. One is 16cm, the other 24cm. This means that triangle 2 is 1.5 times larger than triangle 1. Multiply the known measurement from tringle 1, 11cm by 1.5 and you get 16.5 cm

Which functions are symmetric with respect to the origin?
Damm [24]

Answer:

The correct option is;

y = arcsinx and y = arctanx

Step-by-step explanation:

The given options are;

1) y = arcsinx and y = arccosx

Here, we have at the origin, where x = 0,  arccosx ≈ 1.57 while arcsinx = 0

Therefore arccosx does not intersect arcsinx at the origin for it to be symmetrical to arcsinx or the origin

2)  y = arccosxy and y = arctanx

Here arctanx = 0 when x = 0 and arcos x = 1.57 when x = 0 therefore, they are not symmetrical

3) y = arctanx and y = arccotx

Similarly, At x = 0, arccotx = 1.57 therefore, they are not symmetrical

4) y = arcsinx and y = arctanx

Both functions arcsinx and arctanx pass through the origin and their shapes are similar but inverted as they go from negative to positive.
