#21 the answer is does √ 9^2 + 2^2
a^2 + b^2 = c^2
9^2 + 2^2 = c^2
√ 9^2 + 2^2 = √ c^2
Answer:
y=3x-2
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept
y=3x-2
I think it is the fourth one
The equation for this problem would be:
x+y = 16
Rearranging the equation, it can be expressed as:
y = 16 - x
To obtain ordered pairs, replace random values of x up to 16 to find the value of y. The ordered pairs are tabulated and the graph is shown in the attached picture.
4x+2y=10 Equation 1
x-y=13 Equation 2
Solving by substitution method.
Isolate x from equation 2.
x=y+13
Substitute value of x in equation 1
4(y+13)+2y=10
4y+52+2y=10
6y+52=10
6y=-42
y=-7
Now substitute value of y in x=y+13
x=-7+13
x=6
Answer: (6,-7)
