HElP!! Plzz thanks you

Answer:

y = 4

Step-by-step explanation:

In y =mx+b (slope -intercept form ),

We have m to be the slope

The first and the second equations contains the slope (coefficient of x)

The fourth option clearly states the slope is -5

That leaves with the third option with only a y-intercept.

Answer:

y=4

Step-by-step explanation:

y=4 on the graph would look like this -------------------------- and it would have a slope of zero. It's not x = -5 because that would have an undefined slope |.

And the first two the slope is the number in front of the x.

Hope this helped!!!

Answer:

1.5 miles

Step-by-step explanation:

.3 miles/12 minutes x 5/5 = 1.5 miles/ 1 hour

Recall the following property of exponents:

[tex]a^b\cdot a^c=a^{b+c}[/tex]

[tex]\implies 216^{-3k}\cdot 216^{-2k}=216^{-3k-2k}=216^{-5k}[/tex]

Now, notice that 6² = 36 and 6³ = 216, which means that

[tex]216^{-5k}=36^{2k-1} \iff (6^3)^{-5k}=(6^2)^{2k-1}[/tex]

Recall another property of (real) exponents:

[tex](a^b)^c=a^{bc}[/tex]

[tex]\implies(6^3)^{-5k}=6^{3(-5k)}=6^{-15k}\text{ and }(6^2)^{2k-1}=6^{2(2k-1)}=6^{4k-2}[/tex]

So we have

[tex]216^{-5k}=36^{2k-1} \iff 6^{-15k}=6^{4k-2}[/tex]

Since both sides are equal powers of 6, that must mean that the exponents must be equal, so

[tex]-15k=4k-2[/tex]

Solve for k :

[tex]-15k-4k=(4k-4k)-2[/tex]

[tex]-19k=-2[/tex]

[tex]k=\dfrac{-2}{-19}=\boxed{\dfrac2{19}}[/tex]

Clay and ott are correct but stacie is wrong.

An Arithmetic progression (AP) is a special type of progression in which the difference between two consecutive terms is always a constant. The terms of an arithmetic progression series is a a+d, a + 2d, a + 3d, a + 4d, a + 5d,…

Given here, the sequence as 2,4,6..... thus this is an arithmetic sequence with common difference 2 and therefore the subsequent terms are as follows : 2,4,6,8,18......

∴ Clay and Ott predicted correctly.

Hence, Clay and ott are correct but stacie is wrong.

Step-by-step explanation:

Also there is no following

The ratio of 12gm and 45 kg in simplest form is 3750 : 1.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, Are two weights in different measurement forms, To write them as a ratio we have to make their scale of measurement equal.

We know 1kg is equal to 1000 grams.

Therefore, 45 kg is equal to 45000 grams.

So, The ratio of 12gm and 45 kg is 45000 : 12.

22500 : 6.

11250 : 3.

3750 : 1.

1) A double - blind study is simply an experiment in which neither the participants nor the people who carry out the experiment know who is receiving any particular treatment. This method is usually used in order to prevent a biased view in research results.

2) True because randomized simply means that subjects were assigned to the group randomly.

3) Placebo - controlled trial simply means that there was a control group that received only a placebo treatment which is mainly designed not to have real effect.

Answer:

60%

Step-by-step explanation:

1/5 equals 20 % and thus 3/5 is 20 % multiplied by 3 so 60 %

Answer: "Percent" or "%" means "out of 100" or "per 100", Therefore x% can be written as  

x/100

.

We can then rewrite this as:  60%.

cause i got it right

Hello,

As you have not provided the graph, I can teach you how to answer the question.

You are solving for the slope of the line. The slope can be found by using the following equation:

slope (signified by the variable m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Note that the numbers does not exactly matter, only that what you set as variable [tex]x_1[/tex], the y inside that coordinate will also be [tex]y_1[/tex], and likewise for point 2.

For example, let us say your points for your line is (3 , 6) and (10 , 4)

Let:

[tex](x_1 , y_1)[/tex] [tex]= ( 3 , 6)[/tex]

[tex](x_2 , y_2) = (10 , 4)[/tex]

Plug in the corresponding numbers to the corresponding variables:

slope [tex]m = \frac{4 - 6}{10 - 3} = - \frac{2}{7}[/tex]

The given points will result in a [tex]-\frac{2 }{7}[/tex] slope.

Hope this helps!

Answer:

$390    you divide 520 by 4 so 520/4=130   now we subtract 130 from 520, 520-130=390

Step-by-step explanation:

Solving this question requires basic arithmetic formula and fractions.

New weekly income = $390

Let's call the number of hours kim works weekly as "x"

If she reduces this number of hours by one-fourth and her current weekly income is $520, then it means the amount to be deducted is;

[tex]\frac{1}{4}[/tex] × $520 = $130

Thus, her new weekly income will be;

$520 - $130 = $390

Answer:

y= - 3cosx - 2

Step-by-step explanation:

Our max here is at 1, and the minimum is at - 5

The distance between the x-axis and these points are 1 and 5. 5 + 1/2 = 6/2 = 3, our amplitude. But let's double check. Our middle point is - 2 so...

- 5 - (- 2) = - 5 + 2 = - 3

The amplitude is rather - 3.

f(x) = Acos(Bx + C) + D

Using this we know B = 0, D = - 2 (the middle point), C = 0, and A = - 3 (amplitude). B = 0, and C = 0, as there is no horizontal/vertical shift

f(x) = Acos(Bx + C) + D

f(x) = - 3cosx + (- 2)

f(x) = - 3cosx - 2

y= - 3cosx - 2

Answer:

x + 3y + 9 = 0

Step-by-step explanation:

y=3x + 2

Coefficient of x = 3

Gradient (m) of line y= 3x + 2 is 3

Since the line passing through point

(3,-4) is perpendicular to line y=3x + 2

hence gradient (m) of the line is -1/3;

And hence it equation is given as;

y - y1 = m(x - x1)

y - (-4) = -1/3(x - 3)

multiplying through by 3;

3 × y + 3 × 4 = 3 × -1/3(x - 3)

3y + 12 = -1(x - 3)

3y + 12 = -x + 3

x + 3y + 12 - 3 = 0

x + 3y + 9 = 0
