PLEASE HELP!!

What is the scale factor?

Answer:

x = -3: [tex]y = 10[/tex], x = -2: [tex]y = 4[/tex], x = -1: [tex]y = 0[/tex], x = 0: [tex]y = -2[/tex], x = 1: [tex]y = -2[/tex], x = 2: [tex]y = 0[/tex], x = 3: [tex]y = 4[/tex]

Step-by-step explanation:

Let [tex]y = x^{2}-x-2[/tex], where [tex]x[/tex] and [tex]y[/tex] are the independent and dependent variables, respectively. The approach consists in evaluating the function at values presented in statement:

x = -3

[tex]y = (-3)^{2}-(-3)-2[/tex]

[tex]y = 10[/tex]

x = -2

[tex]y = (-2)^{2}-(-2)-2[/tex]

[tex]y = 4[/tex]

x = -1

[tex]y = (-1)^{2}-(-1)-2[/tex]

[tex]y = 0[/tex]

x = 0

[tex]y = (0)^{2}-(0)-2[/tex]

[tex]y = -2[/tex]

x = 1

[tex]y = (1)^{2}-(1)-2[/tex]

[tex]y = -2[/tex]

x = 2

[tex]y = (2)^{2}-(2)-2[/tex]

[tex]y = 0[/tex]

x = 3

[tex]y = (3)^{2}-(3)-2[/tex]

[tex]y = 4[/tex]

Step-by-step explanation:

because angle A and C are similar, so

9x-8=28

9x=36

x=4

Answer: 10 hours 5 minutes

Step-by-step explanation:

Convert the PM to 24 hour notation: 1720 hrs

Time taken = 1720 - 715

= 1005

= 10 hours 5 minutes

Both of them have to do with adding to the number

Answer:

7 1/2 or 15

Step-by-step explanation:

1/2 time 2 = 1 whole there 15 time 2 equal 30 and halfed is 15

Answer:

15

Step-by-step explanation:

15 times 2 = 30 and divided by 2 equals 15

No, they're not corresponding angles because they are not on the same side of the transversal.

Step-by-step explanation:

==========================================

Explanation:

1/2 = 0.5

Every 60 days, the amount cuts in half.

We start with 904 grams and after 60 days, we have 904*0.5 = 452 grams left over.

After another 60 days, we have 452*0.5 = 226 grams left over.

-------------

Alternative Method:

We can apply the half-life formula.

y = a*(0.5)^(x/H)

where,

In this case,

When x = 120 days go by, we have....

y = a*(0.5)^(x/H)

y = 904*(0.5)^(x/60)

y = 904*(0.5)^(120/60)

y = 904*(0.5)^(2)

y = 904*(0.25)

y = 226 grams of antimony left over.

This method is preferred over the first method if you have x be some non-multiple of 60, or if x is fairly large.

Answer:

Parallel

Step-by-step explanation:

Rearrange the equations and compare with

y = mx + c

where m is the gradient/ slope of the line.

You should see that the two equations have the same value of m, meaning they're parallel.

Answer:

21/2

Step-by-step explanation:

(x-8)/5=2/4

step 1 you simplify if you can to make it easier

(x-8)/5=1/2

step 2 multiply each side by 5

x-8=5/2

step 3 add each side by 8

x=5/2+8

16/2+5/2=21/2

x=21/2

Answer:

12meters

Step-by-step explanation:

Step one:

given data

Length= 4 meters

Width= 3 meters

Let us find the diagonal by applying Pythagoras theorem

[tex]z^2= x^2+y^2\\\\z^2= 4^2+3^2\\\\z^2= 16+9\\\\z^2= 25\\\\[/tex]

z=√25

z= 5meters

Step two:

Hence the total distance Victor has covered is

total= 4+3+5

total= 12meters

Answer:

-7

Step-by-step explanation:

-247 is the value of expression  d³a²−(c+b) for a=−2 , b=3 , c=−12 , and d=−4 .

An expression is combination of variables, numbers and operators.

The given expression is d³a²−(c+b)

d cube times of a square minus c plus d

a,b, c and d are variables

plus and minus are operators.

Given values of a, b c and d are

a=−2 , b=3 , c=−12 , and d=−4 .

Substitute these values in expression

(-4)³(-2)²-(-12+3)

(-64)(4)-(-9)

(-64)(4)+9

Minus two hundred fifty six plus nine

-256+9

Two hundred forty seven

-247

Hence -247 is the value of expression  d³a²−(c+b) for a=−2 , b=3 , c=−12 , and d=−4 .
