What is the slope of the line that passes through point (3,2) and point (6,11)?

Answer:

D

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = - 6 and (a, b) = (- 9, - 3), thus

y - (- 3) = - 6(x - (- 9)), that is

y + 3 = - 6(x + 9)

Step-by-step explanation:

Change the mixed fraction into improper fraction:

2 1/4 = 2 (1/4)(25/25) = 2 25/100 = 2.25

Divide 4 with 2.25

2.25/4 = 0.5625

0.5625 or a little over 1/2 cup of raisins are in each serving.

chad has 280 baseballs because if miguel has 125 MORE than chad then you have to subtract 125 from 405 to get chads baseball cards

To find out how many baseball cards Chad has, subtract 125 from Miguel's total of 405 baseball cards.

To find out how many baseball cards Chad has, we can use the information given in the question. It is stated that Miguel has 125 more baseball cards than Chad and Miguel has a total of 405 baseball cards. So, to find out how many cards Chad has, we subtract 125 from Miguel's total:

Chad's total = Miguel's total - 125

Chad's total = 405 - 125 = 280 baseball cards

Step-by-step explanation:

I take it that these are angles and not sides.

x + x + 2x = 180                All triangles have 180 degrees. Combine the left.

4x = 180                            Divide by 4

4x/4 = 180/4                     Do the division

Final answer:

To find out how much rain a city usually gets, divide the rain it received last year (17 inches) by the percentage of normal rainfall it represented (37%). The city normally receives about 45.95 inches of rain annually.

Explanation:

The student is asking how to calculate the usual annual rainfall for a city if the city received 17 inches of rain last year which was only 37% of their normal rainfall. To find the answer, we want to determine what 100% of their normal rainfall would be. We can use the formula:

Normal Rainfall = (Last Year's Rainfall / Percentage of Normal Rainfall) x 100

Substituting the given values into our formula, we get:

Normal Rainfall = (17 inches / 37%) x 100

Normal Rainfall = (17 / 0.37) inches

Normal Rainfall = 45.95 inches

Therefore, the city usually receives about 45.95 inches of rain annually.

Answer:

D

Step-by-step explanation:

given the 2 equations

x + 2y = 27 → (1)

2x + 3y = 46 → (2)

Rearrange (1) expressing x in terms of y by subtracting 2y from both sides

x = 27 - 2y ← substitute into (2)

2(27 - 2y) + 3y = 46

54 - 4y + 3y = 46

54 - y = 46 ( subtract 54 from both sides )

- y = - 8 ( multiply both sides by - 1 )

y = 8 → D

50 quarts is greater than 12 gallons.

Given that, 12 gallons and 50 quarts.

ANSWER

[tex]\frac{5 - x}{x + 2}[/tex]

EXPLANATION

We want to simplify the rational expression:

[tex]( \frac{1}{x - 4)} )( \frac{ - {x}^{2} + 9x - 20}{x + 2} )[/tex]

We split the middle term to obtain:

[tex]( \frac{1}{x - 4)} )( \frac{ - {x}^{2} + 5x + 4x- 20}{x + 2} )[/tex]

We now factor to obtain;

[tex]( \frac{1}{x - 4)} )( \frac{-x(x - 5) + 4(x - 5)}{x + 2} )[/tex]

[tex]( \frac{1}{x - 4)} )( \frac{(x - 5)(4 - x)}{x + 2} )[/tex]

Or

[tex]( \frac{1}{x - 4)} ) ( \frac{ - (x - 5)(x - 4)}{x + 2} )[/tex]

We cancel the common factors to get;

[tex]\frac{ - (x - 5)}{x + 2}[/tex]

[tex] = \frac{5 - x}{x + 2}[/tex]

Final answer:

The ordered pair (10, -52) is not a solution to the equation y = -5x - 4 because when x is substituted with 10, the equation yields -54, not -52.

Explanation:

To determine which ordered pair is not a solution of the equation y = -5x - 4, you need to plug the x-value from each ordered pair into the equation and see if the y-value matches the result.

The ordered pair that is not a solution is thus (10, -52).

First of all, we can find the angle B by using the fact that the interior angles of a triangle sum up to 180:

[tex]32.5+26.8+B=180 \iff B = 180-32.5-26.8=120.7

[/tex]

Now use the law of sines, which states that the ratio between a side and the sine of its opposite angle is constant. In particular, we have

[tex]\dfrac{\overwrite{BC}}{\sin(A)}=\dfrac{b}{\sin(B)}[/tex]

Plug in the known values and solve for b:

[tex]\dfrac{25}{\sin(32.5)}=\dfrac{b}{\sin(120.7)}\iff b=\dfrac{25\sin(120.7)}{\sin(32.5)}=40.01[/tex]

Answer: OPTION D

Step-by-step explanation:

You can apply the SUBSTITUTION method:

- Solve for x from the second equation and substitute it into the first equation.

- Solve for y:

[tex]x-8y=-57\\x=-57+8y[/tex]

[tex]2(-57+8y)+3y=19\\-114+16y+3y=19\\19y=133\\y=7[/tex]

- Substitute y=7 into any of the original equations ans solve for x. Then:

[tex]x-8(7)=-57\\x-56=-57\\x=-57+56\\x=-1[/tex]

The answer is:

D.

[tex]x=-1\\y=7[/tex]

Substitution method for solving system of equations consists in isolate one variable in terms of the other variable.

So, isolating x in terms of y from the second equation, we have:

[tex]x-8y=-57\\x=-57+8y[/tex]

Then, substituting x into the first equation, we have:

[tex]2(-57+8y)+3y=19\\-114+16y+3y=19\\20y=19+114\\19y=133\\y=\frac{133}{19}=7[/tex]

Now, substituting y into the second equation we have:

[tex]x-8(7)=-57\\x-56=-57\\x=-57+56=-1[/tex]

Answer:

A. 7 more than 2 times m

Step-by-step explanation:

If there's a variable (letter) right next to a coefficient (the number) like in this problem, that means that 2 is being multiplied by m.

Since there's a +7 in the problem, that means thats its being added to or "more than."

Multiplication is "times"

7 is not being multiplied by two or m, it's being added.

So, 2m + 7.

Answer:

3,384 miles

Step-by-step explanation:

If can cover 94 miles in 1/6 of an hour.  (1/6 hour)*6 = 1 hour, so multiply 94 by 6 to see how far the plane will travel in 1 hour.  

94(6) = 564 miles in one hour

Multiply that by 6 to see how far the plane travels in 6 hours

564(6) = 3,384  miles

The airplane can cover 3,384 miles in 6 hours.

The formula for finding the distance covered is:

Distance = speed*time

It is given that it can cover 94 miles in 1/6 hours.

This should be converted to per hour.

For this, multiply the distance by 6.

94 miles * 6 = 564 miles

The speed of the plane is 564 miles per hour.

The distance that the plane covers in 6 hours = 564 miles per hour * 6 hours

= 3,384 miles.

Therefore, we have found that the plane can cover 3,384 miles in 6 hours.
