I need help with this geometryyyy workkk

Answers

Answer:

Perpendicular

Step-by-step explanation:

For this problem, it is important to note two things. One line is completely vertical, and the other line is completely horizontal.

The line y=9 is completely horizontal at the y-value at 9. The line x = 2 is completely vertical at the x-value at 2.

Hence, these two lines would be perpendicular.

Cheers.

Answer:

Perpendicular.

Step-by-step explanation:

Since it makes a huge cross +, which we want it to be, we need the lines to intercept and it makes a right angle. That means it is perpendicular.

. If T is the midpoint of SU, what are ST, TU, and SU?

Answers

Step-by-step explanation:

We have ST=5x, TU=3x+32 and they're equal if T is the midpoint:

5x = 3x + 32

2x = 32 x = 16

ST = 5x = 80

So TU = 80

and SU=160

Approximately how many times greater is 2.3x10^-4 than 1.15x10^-8?

Answers

Answer:

2.3 × is 20,000 times greater than 1.15 ×

Step-by-step explanation:

Given as :

The first number= x = 2.3 ×

The second number= y = 1.15 ×

Let The first number is z times greater than second number

i.e x = z × y

Or, z =

Or, z = 2 ×

∴ z = 20,000

So,The first number is 20,000 times greater than second number

Hence, 2.3 × is 20,000 times greater than 1.15 ×

Point I is on line segment \overline{HJ}
HJ
. Given HI=2x,HI=2x, HJ=4x,HJ=4x, and IJ=4x-10,IJ=4x−10, determine the numerical length of \overline{IJ}.
IJ
.

Answers

Answer:

IJ = 20

Step-by-step explanation:

Point I is on the lines segment HJ. So,

HJ = HI + IJ

Putting all the given values, we get :

4x=2x+4x-10

Taking like terms together, we get :

-2x=-10

x=5

Put the value of x in IJ = 4x-10

IJ = 4(5)-10

IJ = 20

Hence, the value of IJ is 20.

3x-2x+2y+8y= x+10y

I don't add 1 to x coze when x alone stands for 1, I added +10y because both the y equations had + they were positive so I add a +.

HELP!!! WILL GIVE BRAINLIEST!!!! 40 POINTS!!!!!! The agriculture department of a university works with individuals wanting to build greenhouses heated with only plastic. The department raised funding for 3,450 greenhouses. The program started with a group of 310 existing greenhouses. The number grew to 3,262 greenhouses 10 years after inception. Which equation can be used to model the relationship between the number of greenhouses outfitted depending on the number of years since the project began?

Answers

Answer:

Should be something along the lines of:

3,450 = 326x - 310

Step-by-step explanation:

First, let's start with the number of years. Assume the number of years is x. 3262 greenhouses amounts to about 326 greehouses/year. The other number was the existing greenhouses, but we want just how many greenhouses that were built, per the subtraction sign.

Hope this helps!! : )
