Answer:

2x10^5

Step-by-step explanation:

$5 \times {10}^{2} = 5 \times 100 = 500 \\ \\ 2 \times {10}^{5} = 2 \times 100000 = 200000 \\ \\ 200000 > 500 \\ \\ 2 \times {10}^{5} \: is \: greater$

Slope-intercept from of an equation for the line passes through -1,2 and Parallel to y=2x-3

Dennis_Churaev [7]

The equation of the line in slope - intercept form is $y=2 x+4$

Explanation:

The line passes through the points $(-1,2)$ and parallel to the line $y=2x-3$

Since, the line is parallel, the slope is $m=2$

The y - intercept can be determined by substituting the points $(-1,2)$ and $m=2$ in the slope - intercept formula, we get,

$y=mx+b$

$2=(2)(-1)+b$

$2=-2+b$

$4=b$

Thus, the y - intercept is $b=4$

The equation of the line in slope - intercept form can be determined using the formula $y=mx+b$

Thus, substituting $m=2$ and $b=4$ , we get,

$y=2 x+4$

Hence, the equation of the line in slope - intercept form is $y=2 x+4$

Robin has $450 to spend on home repairs. The repairman charges $65 for the initial visit and $37.50 per hour or part of an hour.

laiz [17]

Answer:

6 hours

Step-by-step explanation:

First set up the equation. Seeing the word "per", we know that this will be the variable. The repairman charges an initial fee of 37.50, so we add that fee to the total cost of every hour. To find how much Robin can spend, you set it equal to 450

65x + 37.50 = 450

Now subtract 37.50 from both sides because neither number has a variable, so you can subtract them to simplify the equation

65x = 412.5

To isolate x and find what it's equal to, divide both sides by 65 to get rid of the coefficient.

x = 6.34.

However the answer should be 6 because robin cannot afford a full or part of a 7th hour
