Answer: Second graph is the correct option.

Step-by-step explanation:

Since we have given that

$y=-2(2)x+2\\\\y=-4x+2$

We will find the coordinate on y - axis first,

for coordinates on y-axis then x must be equal to 0.

so, put x=0,

$y=-4(0)+2\\\\y=0+2\\\\y=2$

So, according to this, Second graph has satisfied it.

Hence, Second graph is the correct option.

Find the value of the expression.

Olegator [25]

$( (\frac{3}{5}) {}^{0} ) {}^{ - 2} = (1) {}^{ - 2} = \frac{1}{1 {}^{2} } = \frac{1}{1} = 1$

What is an equation of a line that passes through the point (10,5) and is perpendicular to the line whose equation is y=5/4x-2?

Maurinko [17]

y = mx + b

slope(m) = -4/5

(10,5)...x = 10 and y = 5

now sub into the formula and find b, the y int

5 = -4/5(10) + b

5 = -40/5 + b

5 = -8 + b

5 + 8 = b

13 = b

so ur perpendicular equation is : y = -4/5x + 13 <===

Hope this helps!

17. You have $75 in your bank account. Each week you plan to deposit $8 from your allowance and $10 from your paycheck

Vanyuwa [196]

Answer:

60 weeks

Step-by-step explanation:

195 = 75 + (10 + 8)w

195 - 75 = (10 + 8)w

120 = (10 + 8)w

120 = (2)w

120 ÷ 2 = w

60 = w

Write the inverse of the function: f (x) = 2x+3

34kurt

Answer:

$y = \frac{x - 3}{2}$

Step-by-step explanation:

To find the inverse of a function, simply 'switch' the x and y's and solve for y. $y = 2x + 3$ becomes $x = 2y + 3$ . Now, solving for y, we get $y = \frac{x - 3}{2}$ .

hope this helped! :)
