when we add -1.4 and 1.4 we get zero so its the opposite

Answer:

B

Step-by-step explanation:

Answer:

y = -3x + 9

Step-by-step explanation:

6x + 2y = 18

move 6x to the right of the equation by subtracting on both sides

2y = -6x + 18

then to single out the 'y' divide by 2 on both sides

y = -3x = 9

Answer:

18 kg

Step-by-step explanation:

We can use a proportion.

First, 13 kg 500 g = 13 kg + 500 g = 13 kg + 0.5 kg = 13.5 kg

Proportion:

9 cows is to 13.5 kg as 12 cows is to x

9/13.5 = 12/x

Cross multiply.

9x = 13.5 * 12

Divide both sides by 3.

3x = 4.5 * 12

Divide both sides by 3.

x = 1.5 * 12

x = 18

Answer: 18 kg

Answer:

translation of four units up

Step-by-step explanation:

Answer:

A. translation of 4 units up

Step-by-step explanation:

Take one point from each line, for example:

The y-values of these points are 5 points apart, therefore, f(x) was translated 4 units up to get g(x).

Answer:

46

Step-by-step explanation:

the common one is 2

Answer:

2/3 plus 3/4 is 17/12.

Step-by-step explanation:

this is because the common denominator is 12, and once you add it all you get 17/12 :))

Answer:

congruence, corresponding,sum of 180

Answer:

x= -5

Step-by-step explanation:

f(x) = -5x +10

plug in 35 for f(x)

35= -5x +10

ten move 10 to the other side

25= -5x

then divide by -5

-5 = x

Answer:

X = 20

Step-by-step explanation:

3x + 50 = 6x -10

3x - 6x = -10 - 50

-3x = -60

x = -60/-3

x = 20

Answer:

x = 20

Step-by-step explanation:

Vertically opposite angles are congruent.

6x - 10 = 3x + 50

       6x = 3x + 50 + 10

       6x = 3x + 60

6x - 3x = 60

        3x = 60

          x = 60/3

x = 20

Answer:

A) 0.48

Step-by-step explanation:

The probability that Mrs. Barnes does not check homework if the students take a pop quiz will be 0.77.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

Mrs. Barnes’s class determined the probability that she will check homework on a randomly chosen day is 0.42.

They also determined the probability that she will give a pop quiz when she checks homework is 0.6, and the probability that she will give a pop quiz when she does not check homework is 0.9.

Then the probability that Mrs. Barnes does not check homework if the students take a pop quiz will be =

P = 0.42 x 0.6 + 0.58 x 0.9

P = 0.252 + 0.522

P = 0.774 ≈ 0.77

Answer:

x = 27

Step-by-step explanation:

m<X + m<XWY + m<XYW = 180    (measures of <s of triangle add to 180)

m<X = 90

90 + m<XWY + m<XYW = 180

m<XWY + m<XYW = 90     Equation 1

m<XWY + m<VWY = 180      (linear pair)     Eq. 2

m<XYW + m<ZYW = 180      (linear pair)     Eq. 3

Add Eqs 2 & 3

m<XWY + m<VWY + m<XYW + m<ZYW = 360

m<XWY + m<VWY + m<XYW + m<ZYW = 360

According to Eq. 1, m<XWY + m<XYW = 90.

90 + m<XYW + m<ZYW = 360

Also, m<VWY = 6x & m<ZYW = 4x

90 + 6x + 4x = 360

10x = 270

x = 27

Answer:

k = am + 3mx

Group by taking common factor m

k = m(a + 3x)

Divide both sides by (a +3x)

k / (a+3x) = m

Then, m = k / (a+3x). This is the answer

Answer:

ASA

Step-by-step explanation:

As two lines are parallel, alternate interior angles will be congruent and the side between them is common.

So, ASA congruent

Answer:

the area of the curve y= f(x) = x between x = 5 and x = 10

[tex]A=\frac{75}{2}[/tex]

Step-by-step explanation:

Using the Area formula

[tex]A=\int _a^b\:f\left(x\right)dx[/tex]

As the area of curve lies between x = 5 and x = 10

so

so the integral expression becomes

[tex]A=\int _5^{10}xdx[/tex]

[tex]\mathrm{Apply\:the\:Power\:Rule}:\quad \int x^adx=\frac{x^{a+1}}{a+1},\:\quad \:a\ne -1[/tex]

[tex]A=\left[\frac{x^{1+1}}{1+1}\right]^{10}_5[/tex]

    [tex]=\left[\frac{x^2}{2}\right]^{10}_5[/tex]

     [tex]=\frac{1}{2}\left[10^2-5^2\right][/tex]

     [tex]=\frac{1}{2}\cdot \:75[/tex]

     [tex]=\frac{75}{2}[/tex]

Therefore, area of the curve y= f(x) = x between x = 5 and x = 10

[tex]A=\frac{75}{2}[/tex]

Answer: 21

Step-by-step explanation:

We know 9x - 56 is equal to 6x + 7

So:

9x - 56 = 6x + 7

Add 56 to each side

9x = 6x + 63

Subtract 6x from each side

3x = 63

Now divide each side by 3

x = 21
