How to graph 2x + y = 4 ?
Explain steps please !!
Answers
y= -2x+4
this now matches the formula y= mx+c , -2 being m and 4 being c.
c is your y intercept so the graph will go through 4 on the y axis. Then m is the gradient of your graph and because it is negative you know it is going downwards. 2 means that every unit value you go across the x axis the y axis will go down 2.
To find where your graph crosses the x axis you need to make y=0 in your equation which looks like
0=-2x+4
2x=4
x=2
Now you know that your x intercept is 2 so you can draw a line going through 4 on the y axis and 2 on the x axis like my photo.

Answers
Answer:
-x+y= -14 (get this equation to where you can easily plug it in for a variable)
y= x -14
5x +6y =26 (plug the value above in for y and then solve)
5x + 6 (x-14) = 26 (use the distributive property)
5x +6x - 84 = 26 (combine like terms on the left side)
11x - 84 =26 (add 84 to both sides)
11x = 110 (divide both sides by 11 to isolate the x-variable)
x= 10 (this is the value for x. plug it into the easier equation and solve)
-(10) +y = -14
y= -4
(10, -4) (this is the solution for the system of equations)

-3x+7y=5x+2y Please HELP Complete the missing value in the solution to the equation.
(-5,_)
Answers
Answer:
(-5, -8); the missing value is -8
Step-by-step explanation:
First, you need to simplify the given equation to isolate y
1: -3x + 7y = 5x + 2y (Given)
2: 7y = 8x + 2y (Add 3x to both sides)
3: 5y = 8x (Subtract 2y from both sides)
4: y = 8/5x (Divide both sides by 5)
Now, you can use this to solve for the missing y in value set (-5, y)
where y = 8/5x and x = -5,
y = 8/5(-5)
y = -8
so, the missing value is -8

help with this bounds question please
Answers
Answer: 6.68km/litre
Step-by-step explanation:
Distance(d) = 187km ( to 3 significant figures)
Petrol(p) = 28litres ( to 2 significant figures)
A number, x, rounded to 1 significant figure is 200
Write down the error interval for x
Calculating the lower and upper bound for both 'd' and 'p'
Upper bound 'd' = 187.5km
Lower bound 'd' = 186.5km
Upper bound 'p' = 28.5km
Lower bound 'p' = 27.5km
Therefore,
Petrol consumption (C) = d/p
Upper C = 187.5 / 28.5 = 6.57894
Lower C = 186.5 / 27.5 = 6.781818
Accuracy answer for C = (6.57894 + 6.781818) / 2 = 6.680379
= 6.68km/ litre ( to 3 significant figures)
To achieve a reasonable level of accuracy, the upper and lower bounds of P and D was used to calculate C, which was then averaged.
Using 3 significant figures ensure that we capture the C better, instead of early rounding.

A.) 18.7 units
B.) 10.5 units
C.) 9 units
D.) 13 units
Answers
Answer:
B.) 10.5
Step-by-step explanation:
Use ratios, but be careful.
AE/AD = AB/AC
14/18 = x/(x+3).
14x+42 = 18x
42 = 4x
x = 10.5
The value of x in the given figure is 10.5 so, option B.) 10.5 units is correct.
What is the ratio of two quantities?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b
or
[tex]\dfrac{a}{b}[/tex]
Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.
Using ratios;
AE/AD = AB/AC
14/18 = x/(x+3).
14x+42 = 18x
42 = 4x
x = 10.5
Thus, option B.) 10.5 units is correct.

Jeremy built an office with a floor area of 55/14 square feet. The office is rectangular in shape. If the length of the room is 8 1/2 feet, what is the width of the room?
Answers
Answer:
110/289 feet
Step-by-step explanation:
Step one:
given data
Area of the floor= 55/14 square feet.
The length of the floor= 8 1/2 feet-----convert to simple fraction= 17/2 feet
Step two:
The expression for the area of the room is
Area= L*W
55/14= 17/2*W
55/14=17W/2
cross multiply
17W*14=55*2
289W=110
divide both sides by 289
W= 110/289 feet
