Let the solid line be slope1 and dashed line be slope2

For the dashed line to be perpendicular,the slope has to be:
slope1 x slope2 = -1
thus
3/4 x slope2= -1
slope2 = -4/3

Larry gets $7 for each of the 3 flower beds he weeds and Y dollars to edge a yard. Zach will get $25 to clean a garage and Y dol
lbvjy [14]

Answer:

Expression for Larry will be;

\$21 + \$Y\geq \$X

Expression for Zach will be;

\$25 + \$Y\geq \$X

Step-by-step explanation:

Given:

Larry gets $7 for each of the 3 flower beds he weeds and Y dollars to edge a yard.

Amount for each flower bed he weeds = $7

Number of flower bed he weeds = 3

Total amount he gets for 3 flower bed he weeds = \$7\times 3 =\$21

Amount earn to edge a yard = Y

Total amount Larry will earn = $21 + $Y

Now Zach will get $25 to clean a garage and Y dollars to wash a car.

Amount earned to clean garage = $25

Amount earned to wash as car = $Y

Total Amount Zach will earn = $25 + $Y

The Both have to make X dollars to meet their goals.

Expression for Larry will be;

\$21 + \$Y\geq \$X

Expression for Zach will be;

\$25 + \$Y\geq \$X

Umm it’s to question just label it a and b

A) Scale of map is 1: 30,000

This is assuming that it meant 1 centimetre = 30,000 metres, for it gives no other information.

Multiply 1 with 30,000: 30,000 x `1 = 30,000

30,000 metres is your answer.

B) Scale is 1 inch: 6 miles. You are given 2.5 inches.

Remember that 1 inch = 6 miles.

Multiply 2.5 to both sides: (2.5) * 1 inch = (2.5) * 6 miles

2.5 inch = 2.5 * 6 miles

2.5 inch = 15 miles

15 miles is your answer.

Write a equation of the lines passes through the given points (-2,7) (1,1) the equation is?
vredina [299]

The point-slope form:

y-y_1=m(x-x_1)

m - slope

(x₁, y₁) - point

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (-2, 7) and (1, 1). Substitute:

m=\dfrac{1-7}{1-(-2)}=\dfrac{-6}{3}=-2

y-7=-2(x-(-2))\\\\\boxed{y-7=-2(x+2)}   <em>point-slope form</em>

\boxed{y=-2x+3}     <em> slope-intercept form</em>

\boxed{2x+y=3}       <em>standard form</em>
