What is the solution to −1/4(d+1)<2

kogti [31]

Answer:

$d > -9$

Step-by-step explanation:

$-\dfrac{1}{4}(d + 1) < 2$

First, multiply both sides by -4. You must also change the inequality sign since you are multiplying both sides by a negative number.

$-4 \times \left(-\dfrac{1}{4}\right)(d + 1) > 2 \times (-4)$

$d + 1 > -8$

Subtract 1 from both sides.

$d + 1 - 1 > -8 - 1$

$d > -9$

Barbara requires 2 gallons of paint to cover an area of 800 square feet. Identify the graph for the relationship from quantity t

mote1985 [20]

Answer:

Step-by-step explanation:

x = area to be painted

y = gallons of paint needed

we know already one point of that function/graph :

x = 800

y = 2

so, for a simple relationship between the 2 variables we can assume

y = ax

2 = a×800

a = 2/800 = 1/400

so, we get

y = (1/400) x

for 2400 ft²

y = 1/400 × 2400 = 1/4 × 24 = 24/4 = 6

she needs 6 gallons of paint for 2400 ft².

2y-3x=ay-2x for y <br> please solve for y

babunello [35]

Answer:

$y= \frac{x}{-a + 2}$

Step-by-step explanation:

2y - 3x = ay - 2x

(2y - 3x) + (3x - ay) = (ay - 2x) + (3x - 2y)

2y - 3x + 3x - ay = ay - 2x + 3x - ay

2y - ay = ay - ay -2x + 3x

2y - ay = x

y(-a + 2) = x

$\frac{y(-a + 2)}{-a + 2} = \frac{x}{-a + 2}$

$y= \frac{x}{-a + 2}$

Hope this helps! :D
