QUESTION: 1 1/5 = -2 2/3 x +6 solve for x will give brainliest answer quickly or no brainliest.

Whitepunk [10]

Answer: $x=1\frac{4}{5}$

Simplify both sides of the equation

$\frac{6}{5} =\frac{-8}{3} x+6$

Flip the equation

$\frac{-8}{3} x+6=\frac{6}{5}$

Subtract 6 from both sides

$\frac{-8}{3} x+6-6=\frac{6}{5} -6$

$\frac{-8}{3} x=\frac{-24}{5}$

Multiply both sides by 3/(-8)

$(\frac{3}{-8} )*\frac{-8}{3} x)=(\frac{3}{-8} )*(\frac{-24}{5} )$

$x=\frac{9}{5}$

Turn 9/5 into a Mixed Number

$x=\frac{9}{5} =1\frac{4}{5} \\x=1\frac{4}{5}$

A line with slope 2 passes through the point (2, -4). Find the coordinates of another point on the line.

Brilliant_brown [7]

Answer:

(3, -2)

Step-by-step explanation:

We can view slope as: $\frac{rise}{run}$ (rise / run)

"rise" is the change in y from one point to another

"run" is the difference in x from one point to another

So, if the slope of a line is 2, it rises 2 every time it runs 1 (2 = 2/1)

So, we can find another point on the line by adding 2 to the y-value, and adding 1 to the x-value.

(x, y)

(2, -4)

+ 1 + 2

(3, -2)

So, another point on this graph is (3, -2)

The diameter of a circle is 5.3 cm. What is the circumference

Julli [10]

Answer:

16.642cm

Step-by-step explanation:

Diameter of a circle = 5.3cm

Circumference of a circle = π(d)

= π x 5.3

= 3.14 x 5.3

= 16.642cm

GRAVITY The height above the ground of a ball thrown up with a velocity of 96 feet per second from a height of 6 feet is 6+96t-1

Nata [24]

Here the time function is h(t) = [6 + 96t - 16t^2] feet.

The initial height of the ball is 6 feet. That's when t=0. h(0)=[6+0-0] ft = 6 ft.

At t=7 sec, h(t) = [6 + 96t - 16t^2] feet becomes
h(7 sec) = h(t) = [6 + 96(7) - 16(7)^2] feet This produces a large negative number (-106 ft), which in theory indicates that the ball has fallen to earth and burrowed 106 feet into the soil. Doesn't make sense.

Instead, let t=1 sec. Then h(1 sec) = h(t) = [6 + 96(1) - 16(1)^2] feet
=[6 + 96 -16] ft, or 86 ft.

One sec after the ball is thrown upward, it reaches a height of 86 feet. It continues to rise, slowing down, until it finally stops for an instant and then begins to fall towards earth.
