Answer:

y = 14

Step-by-step explanation:

Since AC = BC then the triangle is isosceles and the base angles are congruent, that is

∠A = ∠B = 50°, thus

∠C = 180 - (50 + 50) ← sum of angles in Δ = 180°

= 180 - 100 = 80°, hence

5y + 10 = 80 ( subtract 10 from both sides )

5y = 70 ( divide both sides by 5 )

y = 14

Butoxors [25]

Answer:

y-intercept: (0, -3)

x-intercept: (5, 0)

Step-by-step explanation:

Trick question! The problem gives you the x and y intercepts. x intercept is when y is 0, and y intercept is when x = 0!

Y=109x <br>y=79x+2506<br> can some one solve both equations and a graph would be helpful plz

Amiraneli [1.4K]

Answer:

x ≈ 83.533

y = 9105.13

Step-by-step explanation:

Step 1: Substitution

109x = 79x + 2506

30x = 2506

x = 83.533

Step 2: Plug <em>x</em> in

y = 109(83.533)

y = 9105.13

15 POINTS! someone pls answer

photoshop1234 [79]

Answer:

$2(\frac{1}{2} *20*50)+2(\frac{1}{2} *20*10)$

Step-by-step explanation:

The formula for the area of a triangle is $\frac{1}{2} *b*h$

The triangles that can be made is the triangle that has legs 20 and 50 and the triangle that has legs 20 and 10.

Since there are 2 of each triangles, we get:

$2(\frac{1}{2} *20*50)+2(\frac{1}{2} *20*10)$

The answer that fits is the first option.
