You will read for 45 minutes if your brother reads for 15 minutes.
<em><u>Explanation</u></em>
You decide to read 30 minutes longer than your brother reads.
If your brother reads 
number of minutes, then 30 minutes longer than minutes means 
minutes.
As the number of minutes you read is 
, so the equation will be: 
When your brother reads for 15 minutes, then we will just <u>plug 
into the above equation</u>. So.....
So, you will read for 45 minutes if your brother reads for 15 minutes.
Answer:
1/4
Step-by-step explanation:
Answer:
a4 = 128
a5 = -512
Step-by-step explanation:
a1= -2
q= (-1)^(n+1) × 4
a4 = a1q³ = (-2) (-4)³ = -2 × -64 = +128
a5 = a1q⁴ = (-2) (-4)⁴ = -2 × 256 = -512
3 in the power of ten means "10^3."
How to solve exponents is to multiply the number as many times as it's exponent. So in this case you will have to multiply ten, three times.
Which would mean that....
The answer is 10^3.
Hope this helps.
Answer:
Slope: 5
Y-intercept: 0
Equation: y=5x
Step-by-step explanation:
Lets look for an equation of the format y = mx + b, where m is the slope and b is the y-intercept (the value of y when x = 0).
Slope is defined as the "Rise/Run" of the line. The change in y(the rise) for a change in x(the run). This can be calculated by taking any two of the given data points. I'll pick (1,5) and (5,25):
Rise = (25 - 5) = 20
Run = (5 - 1) = 4
The Rise/Run, or slope, m, is (20/4) or 5.
<u>The equation becomes y = 5x + b.</u>
To find b, the y-intercept, enter <u>any</u> of the points into the equation and solve for b:
y = 5x + b
y = 5x + b for (4,20)
20 = 5*(4) + b
b = 0
The line goes through the origin at x = 0 (0,0).
The equation is y = 5x + 0 or just y = 5x.
Slope: 5
Y-intercept: 0
Equation: y=5x
