X/2 + y/3 = 6....multiply by common denominator (6) to get rid of fractions..
3x + 2y = 36

3x + 2y = 36
x - y = 2....x = y + 2

3(y + 2) + 2y = 36
3y + 6 + 2y = 36
3y + 2y = 36 - 6
5y = 30
y = 30/5
y = 6

x - y = 2
x - 6 = 2
x = 2 + 6
x = 8

solution is : (8,6)

In order for two lines to be perpendicular, their slopes must multiply together to equal to negative one
So we do negative one divided by 2/5 to get the slope of the red line
Which is -5/2
To check, we do 2/5 multiplied by -5/2 which equals to -1 so our answer is correct

Answer:

a=11

Step-by-step explanation:

Let's solve your equation step-by-step.

√a+5=4

Solve Square Root.

√a+5=4

a+5=42(Square both sides)

a+5=16

a+5−5=16−5(Subtract 5 from both sides)

a=11

Check answers. (Plug them in to make sure they work.)

a=11(Works in original equation)

zhenek [66]

Answer:

The percent error of Heather's calculation is <u>8%</u>.

Step-by-step explanation:

Given:

Heather measures the temperature of her coffee to be 133.4 degrees fahrenheit. It is actually 145 degrees fahrenheit.

Now, to find the percent error of Heather's calculation.

The temperature of coffee Heather measures = 133.4° F.

Coffee's actual temperature = 145° F.

So, to get the measurement in error we subtract the temperature of coffee Heather measures from coffee's actual temperature:

145-133.4=11.6\°.

Now, to get the percent error:

\frac{11.6}{145}\times 100

=\frac{1160}{145}

=8\%.

Therefore, the percent error of Heather's calculation is 8%.
