Answer:
Each table costs $22
Step-by-step explanation:
<u>Step 1: Make an expression</u>
<u>Step 2: Divide both sides by 8</u>
Answer: Each table costs $22
In the X1 and X2 is the same number because a negative number X negative number your result always be a positive number
Answer:
y = 5x - 23
Step-by-step explanation:
Since that is ll to y = 5x - 1, slope must be same as that of y = 5y - 1.
Compare y = 5y - 1 with y = mx + c, where m is slope.
Slope of the required line = 5.
And a point lying on that line is (4,-3). Therefore,
Equation is:
=> y - (-3) = 5(x - 4)
=> y + 3 = 5x - 20
=> y = 5x - 23
Answer:
Step-by-step explanation:
Question 1
System of equations is,
y = -6x -------(1)
y = -4x - 2 ---------(2)
Substitute the value of y from equation (1) to equation (2)
-6x = -4x - 2
-6x + 4x = -2
-2x = -2
x = 1
From equation (1)
y = -6(1)
y = -6
Question (2)
System of equations is,
-y = x --------(1)
3x + 5y = 20 ---------(2)
Substitute the value of x from equation (1) to equation (2)
3(-y) + 5y = 20
-3y + 5y = 20
2y = 20
y = 10
From equation (1)
-y = x
x = -10
Question (3)
System of the equations is,
y = -2x - 7 --------(1)
9x - 10y = 12 ----------(2)
Substitute the value of y from equation (1) to equation (2)
9x - 10(-2x - 7) = 12
9x + 20x + 70 = 12
29x = 12 - 70
29x = -58
x = -2
From equation (1)
y = -2(-2) - 7
y = 4 - 7
y = -3
Just put it on the graph
