This is one method of finding the answer for this,

3:4, 3+4=7

3 part=3/7×280
= 120

4 part =4/7×280
=160
answer=
3:4
120:160
hope it helps....

<span>Just in case you didn't understand them :)

So we start off by breaking it down!!
3:4, 3+4=7 

In other words (or any at that lol) we find out that 280 can be broken off into 3 parts!

3 part=3/7×280  = 120
giving us 120 as the end result! 

</span><span>We also find out that 280 can be broken off into 4 parts!
</span><span>
4 part =4/7×280=160
Leaving us with 160

Meaning that now, we put the two new found ratios together to create our answer!! :)

So, 3:4 now equals 120:160

So your answer will be 120:160

</span> I hope this helps, I know that it helps for me when someone breaks it down for me! :)

Write the ratio for sin x, cos x and tan x
finlep [7]

Answer:

Sin X = 15/17

Cos X = 8/17

Tan X = 15/8

Step-by-step explanation:

Recall, SOHCAHTOA.

Thus:

Sin X = opp/hyp

opp = 15

hyp = 17

✅Sin X = 15/17

Cos X = adj/hyp

Adj = 8

Hyp = 17

✅Cos X = 8/17

Tan X = opp/adj

Opp = 15

Adj = 8

✅Tan X = 15/8

1.Write an equation of the line in point-slope
Oduvanchick [21]

Answer:

<u>Point slope form</u>

y-10 = -6 (x+1)

<u>Slope-intercept form</u>

y=-6x+4

<u>Standard form</u>

4x+y=4

Step-by-step explanation:

Equation in Point slope form is

y-y_1=m (x-x_1) ---------- (1)

Here

m=-5 \ \ \ and \ \ \ (x_1, y_1) = (-1, 10)

Substituting values in equation (1)

y-10 = -6 (x+1) ------------- (2)

Equation (2) is equation of line in point slope form.

<u>Re-arranging equation (2)</u>

y = -6x - 6 + 10

y=-6x+4 ----------- (3)

Equation (3) is equation of straight line in slope-intercept form

<u>Re-arranging equation (3)</u>

<u />4x+y=4   --------(4)

Equation (4) is equation of line in standard form

How do you solve 4b^2+8b+-12=0. Also find the parabole.?
Likurg_2 [28]
First you divide everything by 4 which will become b^2+2b-3=0
Then you can factor this which is
(b-1)(b+3)=0
B=1
B=-3 ... I think that's how you do it
