Answer:
Opening: Opens upwards
Axis of Symmetry: -7/2
Vertex: (-7/2, -81/4)
X - intercepts: (1, 0) and (-8, 0)
Y - intercept: (0, -8)
Step-by-step explanation:
Opening: 'a' is greater than zero
Axis of Symmetry:
[tex]\frac{-7}{2(1)} =\frac{-7}{2}[/tex]
Vertex:
[tex]y= (\frac{-7}{2})^{2} +7(\frac{-7}{2}) -8\\y= (\frac{49}{4}) +(\frac{-49}{2}) -8\\y= \frac{49}{4} +\frac{-98}{4} -8\\y=\frac{-49}{4}-8\\y = \frac{-81}{4}[/tex]
X - intercepts:
(x-1)(x+8)
x = 1 and x = -8
Y - intercept: (0, -8)
[tex]y= 0^{2} +7(0) -8\\\\y= -8\\[/tex]

2xy-yz=8 solve for z
Answers
The solution of the equation in terms of z will be; z = 2x - 8/y
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given the equation as;
2xy-yz=8
Now we have to solve for z;
2xy-yz=8
-yz = 8 - 2xy
Then divide by y on both sides;
z = 2xy/y - 8 / y
z = 2x - 8/y

Answer:
the sum of 8 terms of the series is -65104.
Step-by-step explanation:
The first term is 1.
The common ratio is (-5)/(1) = -5.
The sum of 8 terms is ...
S8 = a1(r^8 -1)/(r -1)
S8 = 1((-5)^8 -1)/((-5) -1) = 390624/-6 = -65104
The sum of 8 terms is -65104.
__
The 8th term is 1·(-5)^(8-1) = -78,125.

it takes an engineer three hours to drive to his brother's house at an average speed of 50miles per hour. If he takes the same route home, but his average speed is 60 miles per hour, what is the time, in hours that it takes him to drive home?
Answers
Answer:
2.5 hours
Step-by-step explanation:
→ Write the formula
Speed = Distance ÷ Time
→ Find the distance for 3 hours at a speed of 50 mph
Distance = Speed × Time ∴ 3 × 150 = 150
→ Now work out the time
150 ÷ 60 = 2.5 hours
