Slope is 3/7,and (4,9) is on the line
TiliK225 [7]

Answer:

y-9=\frac{3}{7}(x-4)

or

y=\frac{3}{7}x+\frac{51}{7}

Step-by-step explanation:

To write the equation of the line using a slope and a point, use the point-slope formula y-y_1 = m(x-x_1). Here m is 3/7. And the point (x_1,y_1) is (4,9). Substitute the values and simplify.

y-y_1=m(x-x_1)\\y-9=\frac{3}{7}(x-4)\\y-9=\frac{3}{7}x - \frac{12}{7}\\y=\frac{3}{7}x -\frac{12}{7} + 9\\y=\frac{3}{7}x + \frac{51}{7}

Both the point slope form and the final simplified form are considered equations of the line.

Is 7 to the 8th power times 7 equivalent to 7 to the the third power times 7 to third power equivalent?
Akimi4 [234]

Answer:

They are not equivalent.

Step-by-step explanation:

Before we solve the question, we need to know that from the laws of indices:

A^x x A^y = A^(x+y).

7 to the power of 8th power means 7^8

7^8 times 7 means 7^8 x 7. From the laws of indices we have 7^8 x 7 = 7^9.

7 to the power of 3rd power means 7^3

7^3 times 7 to the power of 3rd power means 7^3 x 7^3. From the laws of indices we have 7^3 x 7^3 = 7^6.

Obviously, 7^9 ≠ 7^3 therefore, they are not equivalent.

F(x)=-9x^2-7x+8, x=5
VashaNatasha [74]
F(x) = -9x^2 - 7x + 8
f(5) = -9(5^2) - 7(5) + 8
f(5) = -9(25) - 35 + 8
f(5) = - 225 - 35 + 8
f(50 = - 252 <==
