y = 4x - 1
b) 2x + y = 8
4x + 3y = 16
c) -3x + 2y = 19
4x + 5y = 13
d) -3x + 7y = 9
4x - 3y = 7
e) -4x + 5y = -7
x = 23 - 3y
f) y = -x
y = -2/5x - 1/5
Good evening ,
Look at the photo below for the answer.
:)
Answer:
a) x = 1 , y = 3
Step-by-step explanation:
a) 7x + 3y = 16
y = 4x - 1
or
3y + 7x = 16 ... (i)
y - 4x = -1 ... (ii)
Solving the simultaneous equation by substitution;
Equation (ii) tells us that y = 4x - 1
Substituting that in (i) gives;
3(4x - 1) + 7x = 16
12x - 3 + 7x = 16
19x = 16 + 3 = 19
x = = 1
y = 4(1) - 1 = 3

Answer:
The english class would have half as more so divide the amount that the math class has by 2 and then add i to the english class
Step-by-step explanation:
2.Find the constant of variation for the relationship shown in the following table:
x 1 2 3 4
y 4 8 12 16
A.1 B.2 C.3 D.4
3.If f(x) varies directly with x, and f(x) = 8 when x = 6, write the direct linear variation equation. A. f(x) = x B.f(x) = 6x C.f(x) = 8x D.f(x) = x
4.If f(x) varies directly with x, and f(x) = 56 when x = 8, find the value of f(x) when x = 2
A.4 B.7 C.8 D.14
5.Which does not show a direct variation between x and y?
A.y = B.y = 2x C.y = 0.5x D.y =
the answer is D i have this test and its the right answer for 2 reasons
1,its the only thing that looks like english
2,its always the right answer in anime logic
Square root x=13
x=169
Hope you get it!
To solve the equation x^2√x-8+2=7, follow these steps: combine like terms, square both sides, simplify, take the cube root, and simplify again to find x = 3.
To solve the equation x2√x-8+2=7, we need to isolate the variable x. Here are the steps:
Therefore, the solution to the equation is x = 3.
