Solve the inequality -5/4(8x+4)<6-3x. Show your work.

Debora [2.8K]

Answer:

$x>-\frac{11}{7}$

Step-by-step explanation:

<u>Step 1: Distribute</u>

<u /> $-\frac{5}{4} (8x+4)$

$(-\frac{5}{4} *8x)+(-\frac{5}{4} *4)$

$-\frac{40x}{4}-\frac{20}{4}$

$-10x-5$

<u>Step 2: Add 10x to both sides</u>

<u /> $-10x-5\mathbf{+10x}$

$-5$

<u>Step 3: Subtract 6 from both sides</u>

<u /> $-5\mathbf{-6}$

$-11$

<u>Step 4: Divide both sides by 7</u>

<u /> $-11\mathbf{/7}$

$x>-\frac{11}{7}$

Answer: $x>-\frac{11}{7}$

Find the ordered pairs for the x- y-intercepts of the equation 4x+2y=16

erastovalidia [21]

The x-intercept is what 'x' is when 'y' is equal to 0. So plug in 0 for 'y' and solve for 'x':

$\sf 4x+2y=16$

$\sf 4x+2(0)=16$

Simplify:

$\sf 4x=16$

Divide 4 to both sides:

$\sf x=4$

So the x-intercept is (4, 0).

The y-intercept is what 'y' is when 'x' is equal to 0. So plug in 0 for 'x' and solve for 'y':

$\sf 4x+2y=16$

$\sf 4(0)+2y=16$

Simplify:

$\sf 2y=16$

Divide 2 to both sides:

$\sf y=8$

So the y-intercept is (0, 8).

On Tuesday the temperature is 1 ºC. By Wednesday it has dropped to –2 ºC. The temperature drops by twice as much from Wednesday

Finger [1]

Answer: $-8^{\circ}C$

Step-by-step explanation:

Given

The temperature on Tuesday is $1^{\circ}C$

Temperature drops to $-2^{\circ}C$ on Wednesday

Net drop in temperature $1-(-2)=3^{\circ}C$

The temperature drops twice from Wednesday to Thursday

$\Delta T=2\times 3=6^{\circ}C$

Temperature on Thursday

$\Rightarrow -2-6=-8^{\circ}C$
