1. <span>3(z-2)-z=4z-20
</span> 3z-6-z=4z-20
-2z=-14
z=7
2. the slope = (8-5)/(4-10)=-1/2
3. the equation is
(y-8)/(x-3)=3
y-8=3x-9
y=3x-1
4. the <span>slope of a horizontal line is 0
5. to graph the required equation, you can put any values to x , then find the corresponding value of y, for example put x=0, y=2*0+3=3, you can put two different values to x then you will get 2 different sets of coordinates, then you jot the coordinates on the graph paper and you can plot out the line! hope this help you:)</span>
Answer:
The required answer is 54.
Step-by-step explanation:
Given that a = 3 and b = (-1) . And we have to find the value of 2a³ b⁴ .
In such kind of problems , just substitute the given values of a and b to get the required answer .
So here ,
= 2a³ b⁴.
= 2 × (3)³ × (-1)⁴.
= 2 × 27 × 1 .
= 54
Answer:
265
Step-by-step explanation:
The value(s) for which the rational expression −5u+12−2u+2 is undefined is u = 1.
<h3>What is radial expression?</h3>
The expression or an equation which can be undefined at some point is a celled the radial expression.
f(u) = -5u +12 / -2u +2
For the function to be undefined, denominator must be equal to zero.
-2u +2 =0
-2u =-2
u = 1
Thus, the value for which the given expression is undefined is 1.

The volume of a cylinder is
Volume = π (radius)² (length or height)
Volume = π (4 cm)² (15 cm) = 240 π cm³ = 753.98 cm³
