Answer:

z=-8.7

Step-by-step explanation:

-0.3z=-17.4-2.3z

10(-0.3z)=10(-17.4-2.3z)

-3z=-174-23z

20z=-174

z=-8.7

Check:

-0.3z=-17.4-2.3z

-0.3(-8.7)=-17.4-2.3(-8.7)

2.61=-17.4+20.01

2.61=2.61

Write the equation of a line that is parallel to y = -5/4x+ + 7 and that passes through the point (-4,1).

k0ka [10]

Answer: y- 1 = -5/4(x+4)\\

Step-by-step explanation:

y = mx + b, where m is the slope, and in the equation, the slope is -5/4.

For two-line that are parallel, the slope is the same, -5/4.

$y - y_{1}= m( x - x_{1})\\y- 1 = -5/4(x-(-4))\\y- 1 = -5/4(x+4)\\$
