Which expression is equivalent to-g-7+3g-6
Which equation has the same solution as x2 - 6x - 14 = 0?
Answer:
B
Step-by-step explanation:
Given
x² - 6x - 14 = 0 ( add 14 to both sides )
x² - 6x = 14
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 3)x + 9 = 14 + 9
(x - 3)² = 23 → B

Please find answers in the explanation below
Step-by-step explanation:
4. Each unlabelled opposites are positioned at a 0.5 interval. That means each division in between 0 and 1, 1 and 2, 2 and 3, 3 and 4 are 0.5. So we have 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4
Same idea is applicable on the negative side of the graph. We have 0, -0.5, -1, -1.5, -2, -2.5, -3, -3.5, 4.
5. Like 4 above, each unlabelled opposite is positioned at an 0.5 or 1/2 interval.
So we have, 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4 (for the positive side) and 0, -0.5, -1, -1.5, -2, -2.5, -3, -3.5, 4 (for the negative side).
6a.
A positive number is one greater than zero while a negative number is one lesser than zero. So we have -0.5 and 0.5
6b. -0.4, 0.4
6c. -3.5, -3 1/2

Answer:
112.5 miles.
Step-by-step explanation:
2 cm = 25 miles
The question is asking you for the distance between two cities, and is giving you the information that it's 9 cm on the map.
2 cm + 2 cm + 2 cm + 2 cm = 8 cm
25 divided by 2 is 12.5, which would give you 1 cm for the map key.
2 cm + 2 cm + 2 cm + 2 cm + 1 cm = 9 cm
25 miles + 25 miles + 25 miles + 25 miles + 12.5 miles = 112.5

What type of correlation/association exists?
The number of hours you sleep in and the number of hours you are awake during the day
Answer:
Negative Correlation
Step-by-step explanation:
there is a negative correlation between the number of hours you sleep in and the number of hours you are awake during the day as the longer you are either awake or asleep the less time you will be doing the other thing
Here is a graph I made that will hopefully help you understand.
Even if I switched around the label for the x or y-axis, the correlation would still remain the same because the more you stay asleep, the less you will be awake and vice versa.

MY
Which pattern can we use to factor the expression?
U and V are either constant integers or single-variable expressions.
Pro
Choose 1 answer:
Pro
Tea
(U + V)? or (U – V)
e-(U+V)(U-V)
We can't use any of the patterns.
Answer:
The answer is B :
-3x + 4y = 24
4x - y = 7
Answer:
y=7-4x/-1
y=-7+4x
substituting y=-7+4x
-3x+4(-7+4x)=24
-3x-28+16x=24
-3x+16x-28-24=0
13x-52=0
13x=52
x=52/13
x=4
substituting x=4
-3x+4y=24
-3(4)+4y=24
-12-24+4y=0
-36+4y
4y=36
y=36/4
y=9

Answer:
7 is the answer
Step-by-step explanation:
They are based on 7th hrs.
Answer:
7
Step-by-step explanation:
If
4=28
Then let 1 be = x
so;
4=28
1=x
x=¼×28
x=7
This is because 28 can be divided by 4, 7 times.

what is the area of the shape
Answer:
A= 18
Step-by-step explanation:
To find the height, find the blocks inside the shape that is completely attached (they have to be in a straight vertical line). In this case, you can see that three vertical blocks in the middle of the shape is completely attached. That means your height is 3.
To find the width, look at the how many horizontal boxes make up the top. 6 block inside the shape corispond with 6 blocks on top of the shape, so the width is six.
Multiply 6 by 3 to get 18.
I need help please, it’s due in 10 minutes
Answer:
D) 133
Step-by-step explanation:
The total angle of a line is 180 degrees.
If you subtract angle FBE from line FD, you will get angle EBD.
180-47= 133.

Thirty pounds of grass seed will cover One-third of an acre. Which unit rate describes this situation? 10 pounds per acre 40 pounds per acre 90 pounds per acre 120 pounds per acre
Step-by-step explanation:
As always, the "unit rate" can be written two ways. You have not specified which one you want.
.. (30 lb)/(1/3 ac) = 90 lb/ac
.. (1/3 ac)/(30 lb) = (1/90) ac/lb
Answer:
90 pounds per arce

x/2+21=45
what is x in this equation?
Answer:
x = 48
Step-by-step explanation:
x/2+21=45
subtract 21 on both sides
x/2 + 21 - 21 = 45 - 21
x/2 = 24
Multiply by 2 on both sides
x/2 * 2 = 24 * 2
x = 48
Check
48/2 + 21 = 45
24 + 21 = 45
45 = 45 CORRECT
Hope this helped!
HELP I DON’t know how to answer this!!
Answer:
35 ft
Step-by-step explanation:
Since E and F are both midpoints, you can create a midsegment between them. A midsegment is half the length of the line segment parallel to it (the 70 ft) So:

7 plus the sum of a number x and 5 simplified expression:
Answer:
7+(x+5) (original equation)
x+12 (simplified)
Step-by-step explanation:
So we know the number is x
Since its just an expression we can’t make x equal to anything so the best we can do is simplify the expression given.
so 7 plus the sum of x and 5
7+(X+5)
Mow just simplify it
x+5 is x+5
x+5+7 is 12+x becuase 5+7 is 12 and I combined like terms
x+12

If I multiply a number L by another number M, I get 452,199. If I multiply L by the successor of M, I get 454,322. Find L x L.
plz tell the answer fast plz in is urgent :)
Step-by-step explanation:
L * M = 452,199
L * (M + 1) = 454,322
Therefore L * (M + 1) = L * M + L.
=> 454,322 = 452,199 + L, L = 2,123.
Hence L² = 2,123² = 4,507,129.

The cost of polishing 35 identical wooden cubical boxes at the rate of rs. 20 per sq. cm is rs. 1,51,200. Find the edge of each cubical box
Answer: 6 cm
Step-by-step explanation:
Total surface area of cubical box = [tex]6a^2[/tex] , a= edge length of cube (i)
As per given ,
Total surface area of one box = [tex]\dfrac{\text{Cost of polishing}}{\text{Rate} \times\text{Number of boxes}}[/tex]
[tex]=\dfrac{151200}{20\times35}\\\\=\dfrac{151200}{700}\\\\= 216\ sq. cm[/tex] (ii)
Now from (i) and (ii) ,
[tex]6a^2 = 216\\\\\Rightarrow\ a^2= 36\\\\\Rightarrow\ a= 6 \text{ [By taking square root on both sides]}[/tex]
Hence, the edge of each cubical box = 6 cm.
given m and n find the value of x
Answer:
x = 18
Step-by-step explanation:
you can create the following equation to solve for x:
5x - 2 + 5x + 2 = 180
10x = 180
x = 18
an alloy is made by mixing metals A and B in the ratio 3:5
metal a costs £42 per kg
metal b costs £20 per kg
how much would it cost to make 400g of the alloy?
Answer:
11.3
Step-by-step explanation:
First solve how many grams of each mineral you need.
To do this use this equation
[tex]\frac{3}{5} =\frac{x}{y} ; x+y=400[/tex]
Solve the system of equations to get
x=150, y=250
Since there are 1000 grams in 1 kg then the amount of kg of each material you need will be
[tex]x=\frac{150}{1000}; y=\frac{250}{1000}[/tex]
So you need to 0.15 of a kg of mineral a and 0.25 kg of mineral b.
Multiply 0.15 by 42 to get the amount of money needed to buy mineral a.
0.15*42=6.3
Multiply 0.25 by 20 get the amount of money needed to buy mineral b.
0.25*20= 5
Add them to get the final amount
6.3+5=11.3
