=-2(x²-8x+16-16)-35

=-2(x²-8x+16)+32-35

=-2(x-4)²-3

axis of symmetry is x-4=0

or x=4

Answer 2

Answer:

y=2x^2+16x-35

a=2, b=16

Finley's pumpkin had a mass of 6.5 kilograms (kg) before he carved it. After carving it, the pumpkin had a mass of 3.9 kg ​

Answers

Answer:

[tex]\%Change = -40\%[/tex]

Step-by-step explanation:

Given

[tex]Initial = 6.5kg[/tex]

[tex]Final = 3.9kg[/tex]

Required

Determine the percentage change --- Missing from the question

This is calculated as

[tex]\%Change = \frac{Final - Initial}{Initial} * 100\%[/tex]

[tex]\%Change = \frac{3.9kg - 6.5kg}{6.5kg} * 100\%[/tex]

[tex]\%Change = \frac{-2.6kg}{6.5kg} * 100\%[/tex]

[tex]\%Change = \frac{-260}{6.5}\%[/tex]

The basketball coach spent $35 on 5 t shirts for his team last season. This season, he needs to purchase 7 t shirts. If he pays the same rate as last year, how much will the t shirts cost?

Answers

Answer:

5 dollars

Step-by-step explanation:

last year he got 5 they were 7 dollars because 7x5 is 35 so do the same thing to do other it also equals 35

ok so he bought 5 last season and spent 35 last time. we first need to find how many each was for last season. we can do this by dividing 35 and 5.

so 35/5

is 7

the next season he needs to have 7,

2 more then the prior season.

we now know each t shirt is the same price as last season it’ll be $7 each.

so you’d multiply 7x7 which is

$49

final answer: $49

2X-5<9 solve inequality

Answers

Step-by-step explanation:

2x<9+5

2x<14

2x/2<14/2

x<7

Answer:

[tex]\boxed {\boxed {\sf x <7}}[/tex]

Step-by-step explanation:

To solve the inequality you must isolate the variable, which is x.

[tex]2x-5 < 9[/tex]

5 is being subtracted from 2x. The inverse of subtraction is addition, so add 5 to both sides of the equation.

[tex]2x-5+5 < 9+5[/tex]

[tex]2x < 14[/tex]

x is being multiplied by 2. The inverse of multiplication is division, so divide both sides by 2.

[tex]\frac {2x}{2} < \frac {14}{2}[/tex]

[tex]x <7[/tex]

The solution to this inequality is x <7

Which equation represents a line which is parallel to the y-axis?
X=-4y
Y=x-3
Y=-7
X=-8

Answers

Answer:

x = -8

Step-by-step explanation:

If the line is parallel to the y axis, that means it will be a vertical line.

Vertical lines have an equation of x = , because the line will only go through one x value.

They also will not have a slope, because their slope is undefined.

So, the correct answer is x = -8
