Answer:
42
Step-by-step explanation:
√2x-3-3=6
√2x-3=6+3
√2x-3=9
2x-3=9^2
2x=81+3
X=84/2
X=42
So value of X is 42
The temperature one cold morning is -5 °C. By noon, the temperature had increased by 3 degrees and at 4 PM the temperature was zero. The increase from noon to 4 PM was
Answer:
2°C
Step-by-step explanation:
Morning
-5°C
Noon (+3)
-2°C
4pm (+?)
0°C
Equation I used:
(-5) + (3) + x = 0
I'm assuming you're being taught how to work with negative intervals in algebra? Don't worry, that's why you're practising with temperature. Instead of asking online, try using the progress your teacher taught you. If you have notes, look back at them. Practise makes perfect :)

what is 3.78 plus 8.94
Answer:
The answer is 12.72 hope this helps
Step-by-step explanation:
You'll add them it's just like simple addition but you just have to know where the decimal point will be after adding
3.78
+8.94
12.72
When you are adding you start from the back with back I mean the end so when you add 8 plus 4 it's going to be 12 then you write or type the 2 and then carry the 1 and add it to the 7 which is going to be 8 then you add the 8 to the 9 which is going to be 17 that's why we have the 7 there then you carry 1 and add it to the 3 which is going to be 4 and then 4+8 is going to be;12
That's how we got the 12.72
Hope you understand

Which word describes the slope of the line?
Answer:
rate of change
Step-by-step explanation:
Answer:
"rise over run" or "rate of change"
Step-by-step explanation:
"Slope" itself is "rise over run", or how quickly the line moves up or down relative to the x-axis as the value of x changes.
A gradient is really just another name for slope, not a description OF a slope.

(5x+3y)-(2x-7y)+8x please help
Answer:
A I soo sorry but I really can't solve this I have not learned it yet
Answer: 11x-10y
Step-by-step explanation:
Combine like terms.
(5x+3y)-(2x-7y)+8x
3x + 8x
Remember to distribute the negative.
-(-7y) = +7y
3y +7y
Combine like terms once again.
3x+8x= 11x and 3y+7y= 10y

Which decimal is greater ? .0203 or .023
Answer:.023
Step-by-step explanation:
What's the answer to this?
Answer:
steeper
Step-by-step explanation:
D) Vertically compressed
E) Flatter
=====================================================
Explanation:
An example would be if a = 0.5 which leads to the graph being half as tall as it used to be since 1/2 = 0.5; notice how a = 0.5 makes 0 < a < 1 true. Since the graph is squished vertically, the graph is flatter.
We don't have a reflection over the x axis since 'a' is not negative.
----------------
Extra info:
If a > 1 then the graph is stretched vertically to make it taller than it used to be. Eg: a = 5 leads to the graph being 5 times taller than before which also would make it steeper too. The value of d handles the vertical shifting. If d > 0, then we shift up d units. If d < 0, then we shift down |d| units.A camera can take 3/4 of a picture per second.

The line is intercepted with the number one
the slope of the line represented by 3x-5y=-15
Answer:
i think its 3/5
sorry if im wrong:(
Step-by-step explanation:
Answer:
Since the equation '3x + 5y = 15' is transformed to slope-intercept form 'y = (-3/5)x + 3' the slope is (-3/5).
Step-by-step explanation:
Since the equation '3x + 5y = 15' is transformed to slope-intercept form 'y = (-3/5)x + 3' the slope is (-3/5).

A runner saved $25 when he purchased a pair of tennis shoes on sale. If the sale price was 35% off the regular price, what was the regular price of the tennis shoes?
Given:
Amount saved in sale = $25
Sale price was 35% off the regular price.
To find:
The regular price of the tennis shoes.
Solution:
Let the regular price of the tennis shoes be x.
Sale price was 35% off the regular price.
[tex]Discount=\dfrac{35}{100}x[/tex]
Amount saved in sale = $25
[tex]0.35x=25[/tex]
Divide both sides by 0.35.
[tex]x=\dfrac{25}{0.35}[/tex]
[tex]x=71.42857[/tex]
[tex]x\approx 71.43[/tex]
Therefore, the regular price of the tennis shoes is $71.43.
The price of a car was decreased by 16% to £2400. What was the price before the decrease?
Answer:
£2857.14
Step-by-step explanation:
Given parameters:
Cost of car = £2400
Discount = 16%
Unknown:
The original cost = ?
Solution:
Original price - ( 16% x original price) = New price
Original price(1 - 16% ) = 2400
Original price(1 - 0.16) = 2400
Original price x 0.84 = 2400
Original price = [tex]\frac{2400}{0.84}[/tex] = £2857.14

Which equation represents the relationship “4 less than a number is 10?”
Answer:
x - 4 = 10
x = 14
Step-by-step explanation:
Any variable can be used to represent the number, I choose to use "x" in this case.
x - 4 = 10
Inverse operations;
x - 4 = 10
+4 +4
x = 14
