Answer:

Step-by-step explanation:

1. Subtact 152 from 180 because 152 and the angle next to it are corresponding

180 - 152 = 28

2. Add the two angles inside the triangle and subtract them from 180 to find the missing angle

28 + 115 = 143

180 - 143 = 37

angle 1 = 37

The equation of line t is y = -2x + 9. Perpendicular to line t is line u, which passes through

Archy [21]

Answer:

Equation of line u in slope-intercept form is: $\mathbf{y=\frac{1}{2}x+9 }$

Step-by-step explanation:

Equation of line t : y = -2x + 9.

We need to find equation of line u, which is perpendicular to line t and passes through point (-10,4)

The equation must be in slope-intercept form.

The general equation of slope-intercept form is: $y=mx+b$ where m is slope and b is y-intercept

Finding Slope:

If two lines are perpendicular, their slopes are opposite i.e $m=-\frac{1}{m}$

Slope of line t: y=-2x+9 we get m =-2 (Comparing with general form y=mx+b, we get m =-2)

Slope of line u: $\frac{1}{2}$

So, we get Slope of line u: m= $\frac{1}{2}$

Finding y-intercept:

Using slope m= $\frac{1}{2}$ and point(-10,4) we can find y-intercept

$y=mx+b\\4=\frac{1}{2}(-10)+b\\4=-5+b\\b=4+5\\b=9$

Equation of line u:

So, equation of line u, having slope m= $\frac{1}{2}$ and y-intercept b=9, we get:

$y=mx+b\\y=\frac{1}{2}x+9$

So, Equation of line u in slope-intercept form is: $\mathbf{y=\frac{1}{2}x+9 }$

Factor completely: 4x2 + 25x + 6

IceJOKER [234]

(x + 6)(4x + 1)
x times 4x = 4x^2
x times 1 = x
6 times 4x = 24x
6 times 1 = 6
<span>And finally, by adding like terms, 4x^2 + 25x + 6

I hope this helps you! Good luck :)</span>

Elise pays $21.75 for 5 student tickets to the fair. What is the cost of each student ticket?

seraphim [82]

Answer: $4.35 for each ticket

Step-by-step explanation:

You have to find the unit rate; how much does 1 student ticket cost?

We have to divide 21.75 ÷ 5.

21.75 ÷ 5 = 4.35.

So each ticket cost $4.35.

Hope this helps!
