Answer:

Y-Intercept: (0, -5)

Slope: 1/2

Explanation:

The y-int is when x = 0. The slope formula is (y2 - y1)/(x2 - x1) in which you use 2 points on the line.

Could anyone find the length of side x

Answer:

x = 2.4

Step-by-step explanation:

For this equation, you need to use trigonometry. we only need to use one of the two angles given and for this example i'm going to use the 60° angle. as we know the adjacent side and want to know the opposite side, we need to use the trig ratio tan $(\frac{opp}{adj})$ in this case, we will replace the adjacent side with

the square root of 2.

= $\frac{x}{\sqrt{2} }$

as the side we know is on the bottom of the ratio, we need to multiply it by the ratio (tan) then the angle (in case you don't know, * means multiply)

$\sqrt{2} * tan(60) = 2.44948...$ round to 1 decimal place

x = 2.4

Hope this was helpful :-)

I'm sorry if this was confusing, trigonometry is very hard to explain.

Answer:

Step-by-step explanation:

Four more than zero, and Positive four because four above zero is saying that its a positive number. (positive numbers are always greater than zero) so it would be positive four, and Four more than zero.

a bookstore took in$ 167 on the sale of 5 copies of a new cookbook and 3 copies of a new novel the next day it took in $ 89 on t

I am going to use C to represent cookbook and N to represent N. I find that easier to remember which is which.

Day 1: 5C + 3N = 167

Day 2: 3C + 1N = 89

We need to solve one of these equation for either the C or N. I always choose the easiest one! Day 2 looks like the one.

3C + 1N = 89 (I am doing to solve for N because we won't have a fraction)

1N=89-3C

N=89-3C

Now we take this solution for N and put it into our first equation.
