Answer:

K=10 H=65

Step-by-step explanation:

To work out K, you need to know that opposite angles are the same, so 5k is the same as 50, 50÷5= 10, so k=10

To work out H, you know that opposite angles are the same so 2h is the same as 130, 130÷2=65 so h=65

Given:

Line equation => $2.1x + 9.9y - 9.2 = 0$

Required:

x-intercept and y-intercept of the line.

SOLUTION:

The x-intercept is the point where the line intercepts the x-axis. To find the x-intercept of the line for which the equation is given above, set y = 0 and solve for x.

$2.1x + 9.9(0) - 9.2 = 0$

$2.1x + 0 - 9.2 = 0$

$2.1x - 9.2 = 0$

$2.1x - 9.2 + 9.2 = 0 + 9.2$

$2.1x = 9.2$

$\frac{2.1x}{2.1} = \frac{9.2}{2.1}$

$x = 4.4$ (approximated)

The y-intercept is the point where the line intercepts the y-axis. At this point, x = 0. Set x = 0 and solve for y to find the y intercept.

$2.1(0) + 9.9y - 9.2 = 0$

$9.9y - 9.2 = 0$

$9.9y - 9.2 + 9.2 = 0 + 9.2$

$9.9y = 9.2$

$y = \frac{9.2}{9.9}$

$y = 0.9$ (approximated)

Birds bakery has been open 3 times longer than Bridget's bakery and Bridget's bakery has been open for 6 years so how long has B

Natali [406]

Answer:

18 years

Step-by-step explanation:

Given:

Birds bakery has been open 3 times longer than Bridget's bakery.

And Bridget's bakery has been open for 6 years.

So, the Birds bakery open time = 3 $\times$ Bridget's bakery open time

Birds bakery open time = 3 $\times$ 6

Birds bakery open time = 18 years

Therefore, the Birds bakery has been open for 18 years.

Which of the following is equivalent to the to complex number i^21

Debora [2.8K]

Answer:

Step-by-step explanation:

Next time please share the possible answers. Thank you.

Notice that i^4 = 1.

Factoring i^21, we get (i^20)(i^1) = (1)^20i = i

How can you solve an equation with the variable on both sides?

diamong [38]

You should move the variable to the same side!

best by addition/substraction:

for example:

2x+5=3x

I will "move" the 3x:

2x+5-3x=0

now you can add up the variables: -x+5=0 (x=5)

essentially you can move it to the other side, changing the sign: + to -, - to +
