Answer:
There are 182.88 cm in 2 yards.
Step-by-step explanation:
Given that,
1 inch = 2.54 cm
We need to find how many centimeters are there in 2 yards.
We know that,
1 yard = 36 inch
⇒ 2 yards = (2×36) inches
= 72 inches
It means,
72 inches = (72 × 2.54) cm
= 182.88 cm
Hence, there are 182.88 cm in 2 yards.
Howie bought 4 binder for $2.14 each, a pack of pencils for $1.25, and a new coat for $19.95. How much money did Howie spend altogether? A. $23.34 B. $27.34 C. $28.66 D.$29.76
Answer:
A. $23.34
Step-by-step explanation:
The computation of the amount of money spend altogether is given below:
= Purchase price of 4 binder + pack of pencils + new coat
= $2.14 + $1.25 + $19.94
= $23.34
We simply added the above three cost so that the total money incurred would be come
Hence, the correct option is A
What is the Y intercept pls help
Answer:
y- intercept = 1
Step-by-step explanation:
The y- intercept is the point on the y- axis where the graph crosses.
This occurs when the x- coordinate is 0
From the table the point (0, 1 ) is where the graph crosses the y- axis
Then y- intercept = 1
Please help please...
Answer:
(2x + 5)
Step-by-step explanation:
2(x + 1) + 6x = 4(2x + 5) + 2
2x + 2 + 6x = 8x + 20 + 2
8x + 2 = 8x + 22
Because both sides are 8x it will have no solution
Second one is "all of these are correct"
help with this question!
Answer:
y=4x
Step-by-step explanation:
a proportional relationship has to cross through the origin and all of the other answers have y intercepts and if it has a y intercept then it will not pass through the origin.

2x - 8+ 3x + 2 = 4x+10+ 3x - 6
Student Work:
2x - 8+ 3x + 2 = 4x+10+ 3x - 6
5x - 6 = 7x +16
- 5x -5x
-6 = 2x +16
-16 -16
-22 = 2x
2 2
-11= x
Answer:
no(double check my math!!)
Step-by-step explanation:
on the second step it should be 4 not 16 bc 10-6=4
2x-8+3x+2=4x+10+3x-6
5x-6=7x+4
-6=2x+4
-10=2x

Work out the area of the trapezium ABDE.
9 cm
6 cm
Answer:DE = 4
AB = 30
Step-by-step explanation:
Answer:
30cm²
Step-by-step explanation:
AE/BD = CE/CD
9/6 = CE/8
CE = 9/6 x 8
CE = 12cm
DE = CE - CD
DE = 12 - 8 = 4 cm
½(6 + 9)4 = 30cm²
Triangle XYZ at X(–6,1), Y(4,0), Z(1,3) is reflected across the y-axis. What are the new coordinates of the triangle?
Answer:
X(6, 1), Y(-4, 0), Z(-1, 3)
Step-by-step explanation:
When reflecting an image across the y-axis, (i.e, across a vertical line at the position x = 0), All you need to do is negate the x coordinate of each point, so:
(-6, 1) becomes (6, 1)
(4, 0) becomes (-4, 0)
(1, 3) becomes (-1, 3)
Answer:
(6,1) (-4,0) (-1,3)

Of 10 students surveyed in school,7 picked summer as their favorite season.If the school has 350 students,how many can be expected to prefer summer
Answer:
245
Step-by-step explanation:
This is a ratio
7/10 = 70% = the kids who picked summer which leaves off as 30% for an unknown season
7 : 10
245 : 350
The 7 is how many students chose summer, and the 10 is the number of students there are in general
The 245 is the number of students who chose summer, and the 350 is the number of students there are in general
All we had to do was see how many times 10 goes into 350, which is 35 times. So we multiply 10 by 35 and we get 350. Now whatever we do on one side, we need to do it to the other. So 7 times 35 gives us 245. And that's how I know that out of the 350 students there are in total, 245 of them chose summer.
Hope this helped!

Imagine that you are given the graph of a brand new parent function, y = P(x), that you have never seen before. You are then asked to graph y = P(x) + 3. Explain how you would go about graphing this new function.
Answer:
You would move each point on y=P(x) up by three. Or add 3 to each y coordinate
Step-by-step explanation:
This is because we're not manipulating the value of x before it gets multiplied by P.
For example:
If x is set to equal 5 and P equal to 2, then the parent function would have a coordinate of (5,10) since 2(5)=10 but the new function would have a coordinate of (5,13) since 2(5)+3= 13 due to order of operations (2×5 =10, then we add 3).
Answer:
Step-by-step explanation:
Step 1:
Plot y=P(x) from x=-a to x=a with x=0 as the middle point of the distance between a and -a.
Step 2:
Add the value of +3 to each point of y=P(x), ie, y=P(x)+3 meaning that the graph y=P(x) will be pulled up three units on the y axis.
y = 2x – 5 solve for x
Answer:
x= y/2+5/2
Step-by-step explanation:

Identifying Equivalent Expressions
Which expressions are equivalent to 7x - 14? Check all that apply.
14 - 7x
O x-2
-(14 – 7x)
7(x - 2)
3x - 14 + 4x
2x - 10 + 5x + 4
It is -(14-7x)
7(x-2)
3x-14+4x
Answer:
Option c, d and e are equivalent expressions to 7x-14
Step-by-step explanation:
Which expressions are equivalent to 7x - 14
Equivalent Expressions:
The expressions that are the same, even if the expression looks different.
For example: 2x^2+4 is equivalent to 2(x^2+2) because solving 2(x^2+2) we get 2x^2+4
Now, finding equivalent to expressions 7x - 14
Option a) 14 - 7x
Not equivalent to 7x-14
Option b) x-2
Not equivalent to 7x-14
Option c) -(14 – 7x)
Simplifying: -14+7x so, equivalent to 7x-14
Option d) (x - 2)
Simplifying: 7x-14 so, equivalent to 7x-14
Option e) - 14 + 4x
Simplifying: 3x+4x-14 = 7x-14, so, equivalent to 7x-14
Option f) 2x - 10 + 5x + 4
Simplifying: 2x+5x-10+4 = 7x-6 so, Not equivalent to 7x-14
So, Option c, d and e are equivalent expressions to 7x-14
