Answer:

19. y=5x+-1

20. y=-2.5x+4

Step-by-step explanation:

19: 9-4=5

-1+5=4 so m=5

b=-1

so y=5x+-1

20: -1-1.5=-2.5

4+-2.5=1.5

so m=-2.5

b=4

so y= -2.5x+4

The question says “The image shows the front of Bob’s barn.Bob plans on painting the front of his barn,not including the doors o

AleksandrR [38]

Bob need to paint 205 square feet.

Solution:

Length of the door = 7 ft

Breadth of the door = 5 ft

Area of the door = length × breadth

= 7 × 5

= 35

Area of the door = 35 ft²

The given image is a trapezoid.

Top base = 12 ft

Bottom base = 20 ft

Area of the trapezoid = $\frac{1}{2} \times\text{sum of the parallel sides}\times\text{height}$

$$=\frac{1}{2}\times(12+20)}\times15$

$$=\frac{1}{2}\times 32\times15$

= 240

Area of the trapezoid = 240 ft²

Surface area to paint = Area of the trapezoid – Area of the door

= 240 ft² – 35 ft²

= 205 ft²

Hence Bob need to paint 205 square feet.

You have space in your garden for 60 small flowering bulbs. Crocus bulbs cost $0.25 each and daffodil bulbs cost $0.65 each. You

Doss [256]

Answer:

32 daffodils bulbs and 28 crocus bulbs

Step-by-step explanation:

Assuming 'x' as Crocus and 'y' as daffodil. Now we'll form equations.

-> for 60 small flowering bulbs

x+y=60

x=60-y --->eq(1)

->Crocus bulbs cost $0.25 each and daffodil bulbs cost $0.65 each with the budget $27.80

0.25x + 0.65y = 27.80 -->eq(2)

Next is to substitute x=60-y in eq(2)

(2)=>0.25(60-y) + 0.65y = 27.80

15 - 0.25y + 0.65y = 27.80

0.4y = 12.8

y = 12.8/ 0.4

y= 32 daffodil bulbs

Now, plugging the value of y in eq(1)

(1)=>x=60-32

x= 28

x=28 crocus bulbs

Therefore, you can buy 32 daffodils bulbs and 28 crocus bulbs

Find the xx-intercept of each line defined below and compare their values.

alexandr1967 [171]

Answer:

$\displaystyle greater\:than \\ Line\:B: [-6, 0] \\ Line\:A: [2, 0]$

Step-by-step explanation:

The x-intercept of Line B is already given to you because it is where the graph intersects the x-axis.

Now, to get the x-intercept of Line A, plug 0 in for y to get this:

0 = −2x + 4

- 4 - 4

_____________

$\displaystyle \frac{-4}{-2} = \frac{-2x}{-2} \\ \\ 2 = x$

So, the x-intercept of Line A is $\displaystyle [2, 0],$ and since 2 is greater than −6, greater than would be your answer.

I am joyous to assist you anytime.
