Answer:
-3
Step-by-step explanation:
ΔX = 0 – -1 = 1
ΔY = -3 – 0 = -3,
y = -3x – 3, so the slope is -3
Sorry if you don't understand, but pls brainliest for level up
Answer:
x= 1 and y= -1
Step-by-step explanation:
I'm pretty sure it is the just substitution method that you need for this, which is how I solved it and I am confident.
⁴5 because you have have to add 21 and 24 up that's how you find the answer
1^6 is just 1 so 1x=2, you can just take away the one because it is a given that if there is an x there is a 1, so the answer is x=2
Answer:
OD) 4.9 units, 14.2 units
<em> The lengths of the legs of a right triangle</em>
<em> </em>a = 4.9units , b = 14.2units and hypotenuse 'c' = 15
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the Acute angle is 19°
And hypotenuse (AC ) = c= 15
We will take cos∝ = ![= \frac{adjacent side}{hypotenuse}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7Badjacent%20side%7D%7Bhypotenuse%7D)
⇒ ![cos19 = \frac{BC}{15}](https://tex.z-dn.net/?f=cos19%20%3D%20%5Cfrac%7BBC%7D%7B15%7D)
⇒ BC = 15 × cos 19°
⇒ BC = 15 ×0.9455
⇒ BC = 14.18
The length of the one leg of the right angle triangle
BC = b = 14.18≅ 14.2
We know that ΔABC is a right angle triangle
![c^{2} = a^{2} + b^{2}](https://tex.z-dn.net/?f=c%5E%7B2%7D%20%3D%20a%5E%7B2%7D%20%2B%20b%5E%7B2%7D)
a² = c² - b²
= 15² - (14.18)²
= 225 - 201.07
= 23.93
a² = 23.93
a = √23.93 = 4.89≅4.9
<u><em>Final answer:-</em></u>
<em> The lengths of the legs of a right triangle</em>
<em> </em>a = 4.9units , b = 14.2units and hypotenuse 'c' = 15
