He had 105 dollars. 150%=1.5 and 100-30=70 so 70x1.5 =105

Answer:

-2.4

Step-by-step explanation:

Let the unknown number be x.

-3.7 = -1.3(1) + x

-3.7 = -1.3 + x

x - 1.3 = -3.7

x = -3.7 + 1.3

x = -2.4

Answer:

y = -6x + 7

Step-by-step explanation:

In this question, we need to find the equation of a line with the given information.

We know that the line passes through (2, -5).

We also know that the line is parallel to the line 6x + y = 6, which means that it has to have the same slope.

To make it simpler to understand, we can change the equation into slope format:

y = -6x + 6

This means that our new line should have a slope of -6.

With the information above, we can plug in our new values to get the y-intercept of our equations, since we don't have that information.

Plug in your slope and coordinates to the y = mx + b equation and solve for b:

-5 = -6(2) + b

-5 = -12 + b

Add 12 to both sides.

7 = b

Our y-intercept would be b.

Now, we can plug in all our information to get our new equation:

y = -6x + 7

Your answer would be y = -6x + 7

Step-by-step explanation:

Using sine rule

g/sin25=510/sin122

Sin25=0.4226

Sin122=0.8480

g/0.4226=510/0.8480

Cross multiply

0.8480g=0.4226 x 510

0.8480g=215.526

Divide both sides by 0.8480

g=215.526/0.8480

g=254.16

The length of g is 70 inches.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given,

ΔGHI, h = 13 inches, i = 77 inches and ∠G=170°.

We need to find the length of G

Cosine rule: (for all triangles)

c²=a²+b²-2abcos(C)

=13²+77²-2.13.77.cos(175)

=169+5929-2002cos(175)

=6098-2002(0.598)

=6098-1197.2

c²=4901

Take square root on both sides

c=70.01

G=70.01

Hence, the length of g is 70 inches.

What's you question?

Step-by-step explanation:

Answer:

X=6

Step-by-step explanation:

First distribute

ie: 4x-2x+8=-8+4x+4

Next combine like terms

ie: 2x+8=-4+4x

Next subtract 2x from each side and add 4 to each side

ie: 12=2x

Then divide 2 from each side to get x alone

ie: 6=x  

Answer:

-4

Step-by-step explanation:

Looking at the points, one is at (-2,5) and another is at (-1,1)

The line goes down 4 and it goes 1 to the right

The slope is rise over run. In this case the rise if -4 and the run is 1.

Step-by-step explanation:

so for the first one you would enter -9 into all of the x's

g(x)=4x-7

g(-9)=4(-9)-7 ( you would get -36, then you would minus y. so the answer is -43!)

g(-9)=-43

second one would be the same thing

g(x)=x^2-4x+11

g(-4)=-7^2-4(-7)+11

Answer:

3 is the coefficeint of x

Step-by-step explanation:

Answer:

I just graphed the entire thing and none of them are on the line . . .

Answer:

x = (-39)/11

Step-by-step explanation:

Solve for x:

x - 9 = (3 (5 x + 1))/4

Multiply both sides by 4:

4 (x - 9) = (4×3 (5 x + 1))/4

(4×3 (5 x + 1))/4 = 4/4×3 (5 x + 1) = 3 (5 x + 1):

4 (x - 9) = (3 (5 x + 1))

Expand out terms of the left hand side:

(4 x - 36) = 3 (5 x + 1)

Expand out terms of the right hand side:

4 x - 36 = (15 x + 3)

Subtract 15 x from both sides:

(4 x - 15 x) - 36 = (15 x - 15 x) + 3

4 x - 15 x = -11 x:

-11 x - 36 = (15 x - 15 x) + 3

15 x - 15 x = 0:

-11 x - 36 = 3

Add 36 to both sides:

(36 - 36) - 11 x = 36 + 3

36 - 36 = 0:

-11 x = 3 + 36

3 + 36 = 39:

-11 x = 39

Divide both sides of -11 x = 39 by -11:

(-11 x)/(-11) = 39/(-11)

(-11)/(-11) = 1:

x = 39/(-11)

Multiply numerator and denominator of 39/(-11) by -1:

Answer: x = (-39)/11

Answer:

m<JKL = 38.1

Step-by-step explanation:

We are given 2 angles, <DFG and <JKL, which are complementary angles, also that m<DFG = x+8.0 and m<JKL = x-5.8

Complementary angles are angles that add up to 90.

This means that m<DFG plus m<JKL is equal to 90.

As an equation, that would be:

m<DFG + m<JKL = 90

We can substitute m<DFG and m<JKL with their measures.

x + 8.0 + x - 5.8 = 90

Combine the x's.

2x + 8.0 - 5.8 = 90

Subtract 5.8 from 8.0.

2x + 2.2 = 90

Subtract 2.2 from both sides

2x = 87.8

Divide both sides by 2.

x = 43.9

We found the value of x, but we aren't done yet. The question wants us to find the measure of <JKL.

Remember that m<JKL=x-5.8

So, replace 43.9 as x and subtract 5.8 from it.

m<JKL = x-5.8 = 43.9 - 5.8 = 38.1

Answer:

the rate of change is 4.

Step-by-step explanation:

It is 4 because to find the rate of change you need to see how many pieces of corn (y) there are for every serving (x). If you see if you plug in the number three in between 2 and 4 for the servings and you follow the pattern of the table you will get 12. Then you subtract 8 from 12 and you get 4.

so basically the rate of change is the difference in corn for every serving.

Answer:

Step-by-step explanation:

6) Slope = 5

(5 , 40) ; m =5

y - y1 = m(x -x1)

y - 40 = 5 (x - 5)

y -40 = 5x - 25

     y = 5x - 25 + 40

y = 5x + 15

7)  slope = 2

m =2 ;  (-2 , 0)

y - y1 = m(x -x1)

y - 0 = 2(x -[-2])

      y = 2(x +2)

y = 2x +4

Answer:

y - 4 = 2/3(x - 2)

Step-by-step explanation:

The format for point-slope form is: y - y₁ = m(x - x₁)

where m is the slope, x₁ is the x-coordinate and y₁ is the y-coordinate.

In (2,4), 2 is the x-coordinate and 4 is the y-coordinate.

The slope is 2/3.

When you plug in the values, you get:

y - 4 = 2/3(x - 2)

Marketing variables that are included in consumer discrete choice models are often endogenous. Extant treatments using likelihood-based estimators impose parametric distributional assumptions, such as normality, on the source of endogeneity. These assumptions are restrictive because mis specified distributions have an impact on parameter estimates and associated elasticities. The normality assumption for endogeneity can be inconsistent with some marginal cost specifications given a price-setting process, although they are consistent with other specifications. In this paper, we propose a heterogeneous Bayesian semiparametric approach for modeling choice endogeneity that offers a flexible and robust alternative to parametric methods. Specifically, we construct centered Dirichlet process mixtures (CDPM) to allow uncertainty over the distribution of endogeneity errors. In a similar vein, we also model consumer preference heterogeneity nonparametrically via a CDPM. Results on simulated data show that incorrect distributional assumptions can lead to poor recovery of model parameters and price elasticities, whereas the proposed semiparametric model is able to robustly recover the true parameters in an efficient fashion. In addition, the CDPM offers the benefits of automatically inferring the number of mixture components that are appropriate for a given data set and is able to reconstruct the shape of the underlying distributions for endogeneity and heterogeneity errors. We apply our approach to two scanner panel data sets. Model comparison statistics indicate the superiority of the semiparametric specification and the results show that parameter and elasticity estimates are sensitive to the choice of distributional forms. The CDPM specification yields evidence of multimodality, skewness, and outlying observations in these real data sets.

Answer:

y=2x+1.

Step-by-step explanation:

You first need to find the slope of the line already graphed. -2 to 1 would be three units to the right, and -2 to 4 would be six units up. You would use the equation (y2-y1)/(x2-x1), where x1 and y1 would be the x and y values of the first coordinate of the graphed line, and x2 and y2 would be the second coordinate. This would be 6/3, which can be simplified to 2/1, which can be simplified to 2, which would mean the slope of the given line would be 2, as well as the parallel line. Now, you could use a pretty complicated equation to find the y-intercept of the line you need to graph, but I would recommend using the slope to find it. Since the given point is (3, 7), you would need to go to the left, meaning you would reverse the slope until you reach the y-axis, so you would use -2 as the slope. 3*-2=-6, and 7-6=1, so the y-intercept would be 1. The answer would be y=2x+1. Hope this helps.
