Answer:

I think it's 3/4

Step-by-step explanation:

$y = k \times x + n$

On picture we can see that n=-1 and we also use

(x, y) = (-4,-4) and if we put that in function :

$- 4 = - 4 \times k - 1 \\ - 4k = - 3 \\ k= \frac{3}{4}$

Solve the equation. 2 ( 4z - 1) = 3(z+2) Z=

sveta [45]

Answer:

$z = \frac{8}{5}$

Step-by-step explanation:

Calculate for the value of $z$ :

$2(4z - 1) = 3(z + 2)$

-Use Distributive Property on both left and right:

$2(4z - 1) = 3(z + 2)$

$8z - 2 = 3z + 6$

-Take $3z$ and subtract $8z$ :

$8z - 3z - 2 = 3z - 3z + 6$

$5z - 2 = 6$

-Add $2$ to both sides:

$5z - 2 + 2 = 6 + 2$

$5z = 8$

-Take $5z$ and divide on both sides:

$\frac{5z}{5} = \frac{8}{5}$

$z = \frac{8}{5}$

Therefore, the value of $z$ is $\frac{8}{5}$ .

Solve x^2 - 4 = 77.

Gennadij [26K]

Answer:

X = 9 or x = -9

Step-by-step explanation:

We want to solve the quadratic equation

${x}^{2} - 4 = 77$

We shall use the square root method

Let us add 4 to both sides to get:

${x}^{2} - 4 + 4 = 77 + 4$

${x}^{2} = 81$

We take square to get:

$x = \pm \sqrt{81}$

$x = \pm9$

The solution is x=9 or -9

what variable expression should you subtract from both sides of the equation so that you are left with no variables on the right

Scorpion4ik [409]

SOLUTION:

Step 1:

In this question, we are given the following:

Step 2:

The details of the solution are as follows:

What variable expression should you subtract from both sides of the equation so that you are left with no variables on the right-hand side?

The variable expression is: subtract 5x from both sides so that you are left with no variables on the right-hand side

$\begin{gathered} 6x\text{ - 10 = 5x + 15} \\ \text{Subtract 5 x from both sides, we have that:} \\ 6x\text{ - 5x - 10 = 5x - 5x + 15} \\ x\text{ - 10 = 15} \\ \text{Now, add 10 to both sides, we have that:} \\ x\text{ - 10 + 10 = 15 + 10} \\ x\text{ = 25} \\ \text{check:} \\ 6x\text{ - 10 = 5x + 15} \\ \sin ce,\text{ x = 25 , we have that:} \\ 6(25)\text{ - 10 = 5(25) + 15 } \\ 150\text{ - 10 = 125+ 15= 140 ( COR}\R ECT) \end{gathered}$

CONCLUSION:

The final answer is:

$x\text{ = 25}$
