Can someone help me solve this and explain step by step algebraically <br> 1/8x+1/4y=2
mote1985 [20]

Answer:

x=16-2y

Step-by-step explanation:

\mathrm{Subtract\:}\frac{1}{4}y\mathrm{\:from\:both\:sides}

\frac{1}{8}x+\frac{1}{4}y-\frac{1}{4}y=2-\frac{1}{4}y

\mathrm{Simplify}

\frac{1}{8}x=2-\frac{1}{4}y

\mathrm{Multiply\:both\:sides\:by\:}8

8\cdot \frac{1}{8}x=8\cdot \:2-8\cdot \frac{1}{4}y

\mathrm{Simplify}

x=16-2y

Final Answer: x=16-2y

3. g(x) = x^2 - 5x + 3
    g(-3) = -3^2 - 5(-3) + 3
    g(-3) = 9 + 15 + 3
    g(-3) = 27 <==

4. 4(7b + 15f - 8f) =
    4(7b + 7f) =
     28b + 28f <===

5. C = 2.50r + 15
    for 5 rolls...r = 5
    C = 2.50(5) + 15
    C = 12.50 + 15
    C = 27.50...its A

You use a garden hose to fill a wading pool. If the water level rises 16 centimeters every 7 minutes
Sergeeva-Olga [200]
Rise=16, run=7. Slope is rise/run, and therefore is 16/7. The run is considered to be the x coordinate. Since the x coordinate on the point is 21, we know it has moved 3 exact points away from the origin (21/7=3). We can use this movement of 3 exact points to determine the y coordinate as well. Since the rise (y) is 16 for every exact point on a graph, we know the graph has risen 48 units (16x3=48). So, the point ends up being (21,48). The rate of change is 16cm per 7 minutes, or 2.28cm/minute. The equation is Y=(16/7)X (no y intercept because the graph starts at the origin). The equation gives you the y value of 48 when x is equal to 21.
