Find the slope of the line through each pair of point
Rashid [163]

The slope of the line passes through (-6, 3) and (1, 5) is \frac{2}{7}

<u>Solution:</u>

Given, two points are (- 6, 3) and (1, 5)  

We have to find the slope of a line that passes through the above given two points

Slope of a line that pass through \left(x_{1}, y_{1}\right) \text { and }\left(x_{2}, y_{2}\right) is given as:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

\text { Here, in our problem, } x_{1}=-6, y_{1}=3 \text { and } x_{2}=1, y_{2}=5

\text { Slope } m=\frac{5-3}{1-(-6)}=\frac{2}{1+6}=\frac{2}{7}

Hence, the slope the line that passes through the given points is \frac{2}{7}

Really need help<br> Solve the system of equation <br> Y=8x+11<br> Y=5x+29<br><br> X=<br><br> Y=
KonstantinChe [14]

Answer:

(6,35)

Step-by-step explanation:

Set both equations equal to each other and solve for x

8x+11=5x+29, Subtract 5x from both sides

3x+11=29, Subtract 11 from both sides

3x=18 Divide by 3

x=6

Substitute x=6 back into either equation to solve for y

y=8(6)+11

y=48+11

y=59

Need help with this question
-Dominant- [34]

Answer:

C

Step-by-step explanation:

In a right triangle, the side opposite the right angle is the largest side as the right angle represents the largest angle in the triangle. Therefore, as 17.5 is opposite the right angle, we can say that AB²+10²=17.5², and √(17.5²-10²)=AB = 14.4

Using sohcahtoa, we can establish that

sin(∠C) = opposite/hypotenuse = 14.4/17.5, and

arcsin(14.4/17.5) = ∠C = 55°

Because the angles in a right triangle add up to 180 degrees, we can say that ∠A+∠B+∠C = 180°, so ∠A + 90 + 55 = 180 and ∠A = 35°

caleb wants to rent a kayak. Kayak rental cost 14.50 for a half hour.If caleb rents a kayak for one hour and forty-five minutes.
jolli1 [7]
50.75
you multiply 14.50 times 3.5
 the reason why it is 3.5 is because there are two half hours in one hour, and another half hour plus 15 minutes ( which is half of a half hour)
i hope this is clear!!
good luck!!
