Answer:

<em><u>The equality is true</u></em>

Step-by-step explanation:

<em><u>x+(y+z)=(x+y)+z</u></em>

<em><u>x+(y+z)=(x+y)+zwhen we plug in -4/15 for x,-4/5 for y</u></em>

<em><u>x+(y+z)=(x+y)+zwhen we plug in -4/15 for x,-4/5 for yand 17/8 for z,we get</u></em>

<em><u>x+(y+z)=(x+y)+zwhen we plug in -4/15 for x,-4/5 for yand 17/8 for z,we get-4/15+(-4/5+17/8)=(-4/15+-4/5)+17/8</u></em>

<em><u>x+(y+z)=(x+y)+zwhen we plug in -4/15 for x,-4/5 for yand 17/8 for z,we get-4/15+(-4/5+17/8)=(-4/15+-4/5)+17/817/24=17/24</u></em>

<em><u>x+(y+z)=(x+y)+zwhen we plug in -4/15 for x,-4/5 for yand 17/8 for z,we get-4/15+(-4/5+17/8)=(-4/15+-4/5)+17/817/24=17/24so this equality is true</u></em>

Solve the following system of equations for all three variables.
Juli2301 [7.4K]

Answer:

Equation 1: x = 5 y/ 2 − 14  and  y = 2 x /5 + 28/5

Equation 2: y = 9 + 2 z/ 7   and  z = − 63 /2 + 7 y/ 2

Equation 3: y = 7 /3 − 2 z /3   and  z = 7/ 2 − 3 y /2

Determine whether the triangles are congruent. Explain your reasoning .
Nookie1986 [14]

Answer:

Step-by-step explanation:

First use the fact that the sum of interior angles of a triangle is 180° to find the measure of the missing angle

in ΔDEF we have 180 -68 -81 = 31°

in ΔABC we have 180 -68 -33 = 79°

the measure of the angles in ΔABC and ΔDEF are different 33°, 68°, 79° ≠81°, 68°, 31°so the two triangles are not congruent.

What is the y-intercept of the line that passes
lara [203]

The slope is

\frac{-13-31}{1-(-10)}=-4

So, the equation is

y+13=-4(x-1)

The y-intercept is when x=0, so

y+13=-4(0-1) \\ \\ y+13=4 \\ \\ \boxed{y=-9}
