Answer:

y = 40x + 30

Step-by-step explanation:

The equation for a linear function is given by:

y = mx + b;

where y and x are variables, m is the slope or rate of change of the function and b is the initial value of y at x = 0 (that is y intercept).

Let y represent the total cost and x represent the number of hours worked.

The electrician charges 110 after 2 hours of work and 190 for 4 hours of work.

Representing in coordinate form as (x, y) we get:

(2, 110) and (4, 190)

The equation of the function can be gotten using the formula:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

Therefore:

[tex]y-110=\frac{190-110}{4-2}(x-2)\\\\y-110=40(x-2)\\\\y-110=40x-80\\\\y=40x-80+110\\\\y=40x+30[/tex]

Answer:

[tex]\huge\boxed{\sf 4i^2}[/tex]

Step-by-step explanation:

[tex]\sf = -4\\\\We \ know \ that\ i^2 = -1 \\\\= 4 (-1)\\\\= 4i^2\\\\\rule[225]{225}{2}[/tex]

[tex]\huge\mathtt\purple{Answer :- }[/tex]

Let the two numbers be 'm' and 'n'

Now we can get,

1) m + n = 56

2) m - n = 10

m + n = 56

n = 56 - m

m - n = 10

By substituting n = 56 - m we get,

m - (56 - m) = 10

56 - m - m = 10

56 - 2m = 10

-2m = 10 - 56

-2m = -46

m = - 46/-2

Now, we will find 'n' by the equation 1 ,

n = 56 - m

n = 56 - 23

33 + 23 = 56

33 - 23 = 10

Hence, verified

Answer:

2x^1+1

Step-by-step explanation:

Area=L X W

which means that (14x^4+7x^2) needs to be divided by 7x^2

factorise(14x^4+7x^2) which gives 7x(2x^2+1)

divide 7x(2x^2+1) by 7x^2

gives 2x^2 +1

Answer:

The area of a rectangle is (14x^4 + 7x^2) cm²

and its breadth is 7x^2 cm.

it's length is :---

[tex] = \frac{(14{x}^{4} + 7 {x}^{2})}{7 {x}^{2} } \\ = \frac{7 {x}^{2}(2 {x}^{2} + 1) }{7 {x}^{2} } \\ = (2 {x}^{2} + 1) \: c {m}[/tex]

(2x^2+1) cm is the right answer.

Step-by-step explanation:

1. ΔABC=ΔCDE: a) according to the condition BC=CD and AC=CE; b) m∠(BCA)=m∠(DCE).

2. if ΔABC=ΔCDE, then m∠(BAC)=m∠(DEC) and m∠(ABC)=m∠(CDE).

3. if m∠(BAC)=m∠(DEC), then AB || DE (or if m∠(ABC)=m∠(CDE), then AB || DE).

Answer:

9/140

Step-by-step explanation:

9/20⋅5/35

Factor the number: 35= 5⋅7

9/20⋅5/5⋅7

Cancel the common factor: 5

9/20⋅1/7

Apply the fraction rule

9⋅1/20⋅7

Multiply the numbers: 9⋅1=9

9/20⋅7

Multiply the numbers: 20⋅7=140

Answer:

The finding is significant at both α = 0.05 and α = 0.01.

Step-by-step explanation:

Given that:

Null hypothesis : H0: p = 0.65 against the Alternative Ha: p < 0.65,

The test statistic ; z test = - 2.35

From the test statistic value, we can obtain the p value of the test :

To determine if the claim is significant at both α = 0.05 and α = 0.01

We compare the Zstatistic and Zcritical values

If Zstatistic < Zcritical ; then we reject H0; if otherwise, we fail to reject H0

Zcritical at 95% one tailed = - 1.645 (left tail)

Zcritical at 95% one tailed = -2.326 (left tail)

- 2.35 < - 1.645

-2. 35 < 2.326

Since, Zstatistic < Zcritical;

The finding is significant at both α = 0.05 and α = 0.01.

Answer:

No.

Step-by-step explanation:

Your line should start at the point (0,-4) and move up 3 and over 1. The next point should be at (1,-1).

Answer:

This is not correct

Explanation:

To show this, I will use the equation y = 3x - 4.

Let's say that x = 3

In this case, 3x = 9

9 - 4 = 5

So y = 5

Since I can see you have the line hitting 3 on the x axis and the line hitting 2 on the y axis in the same spot, the line is not corresponding with the equation.

So if the line is at 0 on the x-axis, it should be -4 on the y-axis

If it is 1 on the x-axis, it should be -1 on the y-axis

And so on and so forth

Answer:

WY = 12 units.

Step-by-step explanation:

Given the number line

The distance between W and Y can be calculated such as:

WY = [Location of Y] - [Location of W]

WY = [7] - [-5]

WY = 7+5

WY = 12

Therefore, WY = 12 units

1/2 * 1/4 = 1/8

When you divide fractions you can multiply them if you use el reciproco ( not sure how to tell it in English sorry)

Hope this help

The equivalent multiplication equation is 1/2 x 1/4.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

Given:

1/2 ÷ 4​

As, the fraction does not support division.

So, to perform the division we change the division sign into multiplication sign and reciprocate the number on the right side of division sign.

Then, 1/2 ÷ 4​

= 1/2 x 1/4

= 1/8

Hence, the equivalent multiplication equation is 1/2 x 1/4.
