PLEASE HELPP I NEED IT A S A P WILL MARK BRAINLIESTTTT!!!!!
Answer:
-6x - 19y - 56Step-by-step explanation:
Simplify:
-8(2x) + 5(2x - 12) + -2(5y - 2) + (-3) (3y) =-16x + 10x - 60 - 10y + 4 - 9y = x(-16 + 10) + y(-10 - 9) + (-60 + 4) = x(-6) + y(-19) + (-56) =-6x - 19y - 56Answer:
−6x−19y−56
Step-by-step explanation:
−8(2x)+5(2x−12)+−2(5y−2)+(−3)(3y)
Multiply −8 and 2 to get −16. Multiply −3 and 3 to get −9.
−16x+5(2x−12)−2(5y−2)−9y
Use the distributive property to multiply 5 by 2x−12.
−16x+10x−60−2(5y−2)−9y
Combine −16x and 10x to get −6x.
−6x−60−2(5y−2)−9y
Use the distributive property to multiply −2 by 5y−2.
−6x−60−10y+4−9y
Add −60 and 4 to get −56.
−6x−56−10y−9y
Combine −10y and −9y to get −19y.
−6x−56−19y

Amit works for 35 hours and earns £8 per hour.
On Saturday he works for an extra 5 hours and receives 25% extra pay for these hours worked.
Work out the total amount of money that Amit will receive this week.
Answer:
the total amount received by him is £330
Step-by-step explanation:
The computation of the total amount of money that he received is shown below:
For 35 hours, he earns = 35 ×£8 per hour = £280
For extra 5 hours, he earns = 5 × (£8 × 1.25) = £50
Hence, the total amount received by him is £330
Cincinnati is about 225 miles from Cleveland. What is the distance between these cities on the map?
10 millimeters = 25 miles
Answer:90
Step-by-step explanation:
The distance between these cities on the map is 90 mm.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Cincinnati is about 225 miles from Cleveland and on scale 10 millimetres is equal to 25 miles.
The distance on the map will be calculated as,
25 miles = 10 mm
1 mile = 10 / 25 mm
225 miles = ( 225 x 10 ) / 25
225 miles = 90 mm
Therefore, the distance between these cities on the map is 90 mm.

Step-by-step explanation:
f(x) = -x^3 + 3x^2 + x - 3 Using the end behavior of f(x), determine the graph of the function
Answer:
Here, the given function,
Since, the leading coefficient is negative, and degree is odd,
Thus, the end behaviour of the function is,
Therefore, the graph rises to the left and falls to the right.
Now, when f(x) = 0
That is, graph intercepts the x-axis at (3, 0), (1, 0) and (-1, 0).
When x = 0,
That is, graph intersects the y-axis at ( 0, -3),
Also, for 0 > x > -1 , f(x) is decreasing,
For 2.55 > x > 0, f(x) is increasing,
For 3 > x > 2.55, f(x) is decreasing,

A box with no top is to be constructed from a piece of cardboard whose length measures 6 inches more than its width. The box is formed by cutting squares that measure 2 inches on each side from the four corners and then folding up the sides. If the volume of the box will be 14 in^3, what are the dimensions of the piece of cardboard?
Answer:
This is not possible
W = width of cardboard to start with
W+6 = length of cardboard to start with
H =2 (height of finished box)
volume = W x L x H = 14 in^3
if H=2 in, then the area of the base before cutting out the 2x2 corners is W x L = 7 in^2
This is not enough area to cut out the 4 corners of 2x2 each, which would be 16 in^2

The side lengths of a triangle are 9, 12, and 15. Is this a right triangle?
Answer:
Yes, this is a right triangle.
Step-by-step explanation:
If you look more closely, you can notice that it is a 3-4-5 Pythagorean triple and it was multiplied by 3 to get 9-12-15.
Or you can do it using the Pythagorean Theorem directly:
9^2 + 12^2 = 15^2
and that is true.
Answer:
yes it is.
Step-by-step explanation:
pythagorean theorem. A^2 + B^2 = C^2

Answer:
(-4, -5)
Step-by-step explanation:
-4x + 2y = 6
-4x + 2(x - 1) = 6
-4x + 2x - 2 = 6
-2x - 2 = 6
-2x - 2 + 2 = 6 + 2
-2x = 8
-2x/-2 = 8/-2
x = -4
------------------------
y = x - 1
y = -4 - 1
y = -5

Can someone please explain how to do this problem for me?
Answer:
We always start with the x because in the alaphbet x is before y. So it says x=1 and the graph is skipping by 2 so in the middle of where the interact and beside positive 2 on the x row is where the 1 is so you keep it there for now. Now for the y you can see the middle where the interact well that is 0 so you have to keep the dot on the x place because if it said y=2 we would move it but is says 0 so we dont move it!

The average of six numbers is 4. If the average of two if those numbers is 2,what is the average of the other 4 numbers?
Answer: Average of other 4 numbers =5
Step-by-step explanation:
Sum of n numbers = Average of n numbers x n
Given: Average of 6 numbers =4
so sum of 6 numbers = 6x 4 = 24
Average of 2 numbers = 2
Sum of 2 numbers = 2 x 2 =4
Sum of rest of 4 numbers = sum of 6 numbers - Sum of 2 numbers
= 24-4
=20
Average of 4 numbers = [tex]\dfrac{20}{4}[/tex]
i.e. Average of 4 numbers =5
