PLEASE HELP ME!!! I don't understand.... If possible, please explain!

Mathematics
1 answer:
gogolik [260]3 years ago
8 0

Answer:

55

Step-by-step explanation:

Since this is an isosceles triangle, the angles at the bases of the identical legs must be equal

<A = <C

3x+40 =x+50

Subtract x from each side

3x-x+40 = x+50-x

2x +40 = 50

Subtract 40 from each side

2x+40-40=50-40

2x = 10

Divide each side by 2

2x/2=10/2

x = 5

We want to find <A

3x+40

3(5)+40

15+40

Find an explicit formula for f(n)<br> f(1)=−62 f(n)=f(n−1)+5<br> ​
Aleks04 [339]

Answer:

  • f(n) = 5n - 67

Step-by-step explanation:

<u>Given</u>

  • f(1)=−62
  • f(n)=f(n−1)+5

<u>Property of AP</u>

  • aₙ = a₁ + (n-1)d
  • a₁ = -62, d = 5

<u>Applying same on the given function</u>

  • f(n) = -62 + (n-1)*5 = -62 + 5n - 5 = 5n - 67
  • f(n) = 5n - 67

What is the equation of the line that passes through the point (−0.5,8) and has a slope of −5?
natima [27]

Answer:

Slope=-1.8, X=-0.5, y=1.9

Equation is y^2-y^1=m(x^2-x^1).

Y-1.9=-1.8(X-(-0.5))

Y-1.9=-1.8x+0.90

Add 1.9 on both sides.

Y= -1.8x+1.

I hope this helps you.

Oki I have a few but I’m giving a lot of points I just didn’t feel like doing them separate.
Ghella [55]
Given two angles of a triangle, we can find the third one by subtracting what we have from 180:
180-63.2-75.9=40.9°.  This means C is correct.
This also means that B is correct; if a triangle is equilateral, all angles must be congruent as well, which these are not.

Cross multiplying the proportion we have:
x*1 = 3(y-3)
1x = 3y - 9
Solving for y, we first cancel the 9 by adding:
1x+9 = 3y
Now we cancel the 3 by dividing:
1x/3 + 9/3 = 3y/3
1/3x + 3 = y
In this format, we can see that the slope (m) is 1/3 and the y-intercept (b) is 3.

Going by the directions for the points P, Q, R, and S, PQ would be parallel to SR and PS would be parallel to QR.  These sides are not parallel to any other sides of this figure.

For the last problem, the vertices given do not form a parallelogram.  There is only 1 pair of parallel sides using these points.
