Answer:

C. y = -2x + 3

Step-by-step explanation:

The equation of a line in slope-intercept form is given as y = mx + b.

m = slope, while b = y-intercept.

We already know that the slope, m, = -2.

We are given a point also as (0, 3). This means, at x = 0, y = 3.

Therefore, the y-intercept, b, = 3, because, the line would intercept the y-axis of the graph at y = 3, and at that point, x = 0.

Thus,

Slope (m) = -2,

y-intercept (b) = 3

Plug these values into y = mx + b

✅The equation of the line in slope-intercept form would be:

y = -2x + 3

How many different five digit members can be formed from the digits 5, 6, 7, 8 and 9 if digits can be repeated? If digits cannot

Dafna11 [192]

Answer:

Solution given:

5,6,7,8,9,

When repeated:

it has

5 ways for each

different five digit members can be formed from the digits:5*5*5*5*5=<u>3125</u>

When not repeated:

it has

5 ways for 1st

4 ways for 2nd

3 ways for 3rd

2 ways for 4th

1 ways for 5th

different five digit members can be formed from the digits:5*4*3*2*1=<u>120</u>

Answer:

Q. 2)Perimeter =2(l+b)

So,

2(8x-8 +8x)=80cm(Given in Question)

= 2*16x-8=80cm

16x- 8= 80 divided by 2,

16x=40+8=48

x=48 divided by 16

X=3

Q.1) Perimeter=2(l+b)

2(2x+8 +4x)=76cm(Given in Question)

2* 6x +8=76

6x+8= 76 divided by 2, 38

6x= 38-8, 30

x= 30 divided by 6 = 5

X=5

Last month you spent $40 on clothing. This month you spent 120% of what you spent last month. Set up a proportion to model thi

andreyandreev [35.5K]

Answer:

$48

Step-by-step explanation:

Given that:

Money spent on clothing last month = $40

Money spent this month is 120% of the spending of the last month.

To find:

A proportion to model this situation.

And the spending done this month?

Solution:

Let us have a look at 120% first.

$120\%= \dfrac{120}{100} = \dfrac{6}{5}$

$\frac{6}{5}$ of $x$ can be found by comparing $x$ with 5, then we have to find the equivalent of 6.

Here, $x$ is 40.

5 parts are equivalent to 40

1 part is equivalent to $\frac{40}{5} = 8$

6 parts are equivalent to $8\times 6 = 48$

simply:

$40 \times \dfrac{120}{100} = 48$
