Answer:

y= 1x-5

Step-by-step explanation:

This grpah shows a linear equation, for which the formula is y=mx+b. M is the slope, and b is the y-intercept, which means the point on the y-axis when x is zero.

So far= y=_x-5

Now to find the slope, you can take 2 points and use the slope formula, which is [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

I used the points (1,-4) and (0, -5)

(1,-4)

[tex]x_{2} , y_{2}[/tex]

(0,-5)

[tex]x_{1} ,y_{1}[/tex]

Plug into formula

[tex]\frac{-4-(-5)}{1-0}[/tex]

negative minus negative becomes a positive

[tex]\frac{-4+5}{1}[/tex]

[tex]\frac{1}{1}[/tex]

The slope is 1, so the equation of the graph is

y= 1x-5

Answer:

Linear equations take the form: y = mx + c

y is the dependent variable i.e the money that Naomi has to pay in total.

x is the independent variable which in this case is weeks.

m is the slope and this shows the change as a result of x. It should therefore represent the weekly payment as this is increases per week.

c is a the y-intercept which means its a fixed figure that doesn't change. It will therefore be the down payment because that does not change.

Plan A:

Naomi wants to pay $840. Using the formula format and explanation above (replace x with w so it makes more sense), the formula will be:

840 = 60w + 180

Plan B:

This has no down payment so there will be no y-intercept.

840 = 70w

Answer:

x1 = x 61 = 6

x0 = 1 70 = 1

x-1 = 1/x 4-1 = 1/4

xmxn = xm+n x2x3 = x2+3 = x5

xm/xn = xm-n x6/x2 = x6-2 = x4

(xm)n = xmn (x2)3 = x2×3 = x6

(xy)n = xnyn (xy)3 = x3y3

(x/y)n = xn/yn (x/y)2 = x2 / y2

x-n = 1/xn x-3 = 1/x3

Step-by-step explanation:

When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.

If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.

Answer:

214.......................

Answer:

First question: Answer is C

Second question: Answer is C

Third question: Answer is A

Step-by-step explanation:

For the first question, the option is C since there were 5 interviewees per week, which gives a total of 5x12 = 60, that is, an exact sample population of 60.

For the second question, the exact population is of all the 250,000 households that are being contacted by the ACS.

For the third question, the population is 1161 American adults who if they provide information about the political party that they believe has better ideas to lead the country in the 21st century,

Answer:

Therefore we fail to reject the Null hypothesis [tex]H_0[/tex]

Because the is no sufficient evidence to support the claim of the alternative hypothesis [tex]H_a[/tex]

Step-by-step explanation:

From the question we are told that

Sample size [tex]n_1 =52[/tex]

Mean time 1 [tex]\=x_1=24.04\ hours[/tex]

Mean time 2 [tex]\=x_2=24.52\ hours[/tex]

Standard deviation [tex]\partial _1=5.769[/tex]

Standard deviation [tex]\partial _2=5.556[/tex]

Level of significance 0.05

The null hypothesis is [tex]H_o: \mu_1=\mu_2[/tex]

Alternative hypothesis [tex]H_a: \mu_1<\mu_2[/tex]

Generally the test statistics is mathematically represented as

      [tex]Z= \frac{\=x_1-\=x_2}{\sqrt{\frac{\sigma_1^2}{n_1}+\frac{\sigma_2^2}{n_2}}}[/tex]

     [tex]Z= \frac{24.04-24.52}{\sqrt{\frac{5.769^2}{52}+\frac{5.5562^2}{52}}}[/tex]

     [tex]Z= -0.4321583379[/tex]

     [tex]Z= -0.43[/tex]

From Table the Z-critical value at [tex]\alpha =0.05\ is\ -1.6449[/tex]

Therefore

Zcal> Zcritical

(-0.43)=(-1.645)

Generally we fail to reject the null hypothesis [tex]H_0[/tex] at [tex]\alpha = 0.05[/tex]

Therefore we fail to reject the[tex]H_0[/tex]

Because the is no sufficient evidence to support the claim of [tex]H_a[/tex]

Answer:

34.05

Step-by-step explanation:

Subtract 65 from 575.75 and then divide that number by 15

Solve for k

by simplifying both sides of the equation, then isolating the variable.

Exact Form:

k= −45/28

Decimal Form:

k=−1.60714285…

Mixed Number Form:

k= −1 17/28

so its the top one :)

Answer:

r = 3/2

Step-by-step explanation:

The common ratio (r) is the number that, when multiplied by the previous (n-1) term, gives the nth term of the geometric sequence ([tex]a_{n} =a_{n-1}*r[/tex]). To find the common ratio, we can take any term and divide it by its preceding term (rearrange the formula to get [tex]r=\frac{a_{n}}{a_{n-1}}[/tex]). If we take 24 and divide it by 16, we get the common ratio of 3/2 ([tex]r=\frac{24}{16}[/tex], [tex]r=\frac{3}{2}[/tex]). Hope this helps.

Answer:

they are just multiplying thr numbers on top for exsample 42÷6=7

Step-by-step explanation:

you should see what numbers dose the bottom numbers have in common and multiply by 15.

Step-by-step explanation:

Given system of equations are :

-3y = x+5 ....(1)

y = 2x+2 ...(2)

We need to find the solution of the equations.

Multiply equation (2) by 2.

-6y = 2x+10 ...(3)

Subtract equation (2) and (3).

y-(-6y)= 2x+2-(2x+10)

7y=2x+2-2x-10

7y=-8

y = 8/7

Put the value of y in equation (2)

[tex]\dfrac{8}{7}=2x+2\\\\\dfrac{8}{7}-2=2x\\\\x=\dfrac{\dfrac{-6}{7}}{2}\\\\x=\dfrac{-3}{7}[/tex]

Hence, this is the required solution.

We conclude that:

Step-by-step explanation:

Given

We have the function

f(x) = -x² - 10

To determine

f(-4) = ?

Calclulating f(-4)

substitute x = -4 in the function

f(x) = -x² - 10

f(-4) = -(4)² - 10

f(-4) = -16 - 10

f(-4) = -26

Therefore, we conclude that:
