Write the equation of a line with a slope of −1 and a y-intercept of −6. (2 points)

Answer:

x = 19.5, RQS=43

Step-by-step explanation:

It is important to note that RQS and TQS are supplementary, meaning their angles will add up to 180. Knowing this, we can create and solve the equation to find x..

(2x+4) + (6x+20) = 180

8x + 24 = 180

8x = 156

x = 19.5

Now that we know the value of x, we can substitute it into the equation for RQS, 2x+4.

2(19.5)+4

39+4

43

Hope this helped!

Answer:

[tex]x=19.5^o[/tex]

[tex]\angle RQS=43^o[/tex]

Step-by-step explanation:

Notice that the addition of these two angles give you and angle of [tex]180^o[/tex], therefore we can write the following equation to represent such addition:

[tex](2x+4)^o + (6x+20)^o=180^o\\2x+6x+4^o+20^o=180^o\\8\,x+24^o=180^o\\8\,x=180^o-24^o\\8\,x=156^o\\x=156^o/8\\x=19.5^o[/tex]

Therefore, the value of the angle RQS is:

[tex]\angle RQS=(2\,x+4)^o=(2\,*\,19.5^o)+4^o=43^o[/tex]

The equation is y = x +3 .

We have to check which one of the option does not fulfill the given equation .

Taking 1st option :-

Where x = -10 and y = -7

→ -7 = - 10 +3

→ -7 = -7

Hence this lies on graph.

Taking 2nd option :-

Where x = 13 and y = 16

→ 16 = 13 + 3

→ 16 = 16

It also lies on graph .

Taking 3rd option :-

→ Where x = -14 and y = -11

→ -11 = -14 +3

→ -11 = -11

This will also lie on graph .

Taking 4th option :-

Where x = -20 and y = 17

→ 17 = -20 + 3

→ 17 = 17

This will also gonna lie on graph .

Answer:

  B.  y = 4/3x + 1

Step-by-step explanation:

The offered choices are in slope-intercept form:

  y = mx + b

where m represents the slope (rise/run) and b represents the y-intercept.

The graph crosses the y-axis at y=1, so the y-intercept is +1. That eliminates choices A and D.

The slope is greater than 1, so choice C is eliminated. You know the slope is greater than 1 because the line goes up more than 1 unit for a 1-unit change to the right. If you look where the line crosses grid points, you see that it rises 4 units for a run of 3 units to the right. That means ...

  m = rise/run = 4/3

The equation is ...

  y = 4/3x +1 . . . . matches choice B

Answer:

B. y = 4/3x + 1

Step-by-step explanation:

First, find the slope using rise/run (y2 - y1) / (x2 - x1)

Use the points (0, 1) and (3, 5)

Plug in the numbers:

(5 - 1) / (3 - 0)

= 4/3

Looking at the graph, we can see the y intercept is (0, 1) so we can plug in 1 into the equation y = mx + b as b:

y = mx + b

y = 4/3x + 1

Answer:

The expression is T = b+s

Step-by-step explanation:

If b represents the number of bikes and s represents the number of skateboards Donte is planning to repair to save up money for college, the total number of things he can repair in a day will be expressed as the sum of number of bikes and number of skateboards i.e b+s = T

Given that He can repair up to 2 bikes per day, the total and 4 skateboards per day this means that b = 2 and s = 4

Total number of thing's he can repair in a day given this amount T = 2 + 4 = 6 things

5x² + 2x - 15 = 0

Step-by-step explanation:

Given

[tex]\frac{6}{x}[/tex] = 2x + [tex]\frac{4}{5}[/tex]

Multiply through by 5x ( common denominator )

Hey there! I'm happy to help!

We have two values for y. Since y=y, this means that −2x + 4 and − 1/3x − 1 are equal as well, so we can put them in an equation and solve for x.

−2x + 4 = − 1/3x − 1

We subtract 4 from both sides.

-2x=-1/3x-5

We add 1/3 x to both sides.

-5/3x=-5

We divide both sides by -1 2/3.

x=3

Now, we plug this into one of the original equations to find y.

y=-2(3)+4

y=-6+4

y=-2

Therefore, the solution is (3,-2) or x=3 and y=-2.

Answer:

60, 120 and 180.

Step-by-step explanation:

It maps onto itself every 60 degrees.

So as they are multiples of 60 it will map onto itself at 120 and 189 degrees also.

The measure of the angle by which David can rotate the hexagon to map it onto itself is 60°, 120°, and 180°. The correct options are C, D, and E.

When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."

Given that David uses drawing software to rotate the regular hexagon about its center. Now, since the measure of the center angle of a hexagon made by any of its sides is 60°.

Further, if the hexagon is rotated by any angle that is divisible by 60° then it will result in the same hexagon.

Hence, the measure of the angle by which David can rotate the hexagon to map it onto itself is 60°, 120°, and 180°.

B) -4<x<2

Step-by-step explanation:

-1 < x + 3 < 5

-3       -3      -3

-4 < x + < 2

We have some unknown number x and we're adding 3 to it getting x+3

To isolate x, we need to undo the operation happening to it. So we need to undo the addition of 3. We'll subtract 3 from all sides

-1 < x+3 < 5

-1-3 < x+3-3 < 5-3 ... subtract 3 from all sides

Answer: We have an odd number of pennies.

Step-by-step explanation:

So we have N pennies.

When we wan to divide the N pennies into groups of 2, we have a penny left over.

This means that N is not divisible by 2.

The problem is that there are infinite natural numbers that are not divisible by two, this is the set of odd numbers.

And remember that an odd number can be written as:

N = 2*k + 1.

where k is an integer.

Then we want to divide this by 2 (divide N into groups of 2)

we have:

N/2 = (2*k + 1)/2 = 2*k/2 + 1/2 = k + 1/2.

So we have k groups of 2 pennies, and a penny leftover that we can not divide into two.

Answer:

The critical region is F >F ₀.₀₁ (2,18) = 6.01

Step-by-step explanation:

For 1 way ANOVA the degrees of freedom Between Samples would 2 and within Samples would be 18 .

Alpha is given  to be = 0.01

v1 = k-1 and v2 = n-k

Where k is the number of rows and n is the total number of values

v1= 3-1= 2   and v2 = 21-3= 18

So if we look up the table we find the values of the critical region to be 6.01

Hence the critical region is less and equal to 6.01

The critical region is F >F ₀.₀₁ (2,18) = 6.01

48 burpees & 80 squats

Step-by-step explanation:

Let burpees= x

Let squat = y

For every 12 burpees Melinda did, she did 20 squats.

X/y =12/20

20x= 12y

X= 0.6y

Melinda did a total of 128 squats and burpees

X+y= 128

But x= 0.6y

0.6y +y= 128

1.6y= 128

Y= 128/1.6

Y= 80

X+y= 128

X+80= 128

X=128-80

X= 48

Step-by-step explanation:

AA (Angle-Angle) Similarity postulate is exactly what it sounds like: Two triangles can be proven similar if they have two congruent angles.

We can tell what angles are congruent through the markings:

(A) and (B) can be immediately be eliminated, because one or more tringle in the pair does not have enough markings to prove congruency, so therefor cant be proven to be similar.

(D) is a little more difficult to decipher, but when you look closely, you can tell that the markings are not identical, so therefor  the angles are not congruent.

(C) is correct because it has identical markings which makes the angles congruent.

Hope this helps :)

Option C is correct because it has identical markings which makes the angles congruent by AA.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

Two triangles can be proven similar if they have two congruent angles.

Option A and B are not similar through AA because one or more tringle in the pair does not have enough markings to prove congruency, so therefore they are not similar.

Option C is correct because it has identical markings which makes the angles congruent by AA.

Hence, Option C is correct because it has identical markings which makes the angles congruent by AA.

Computation:

⇒ New segment AD = AB + CD

⇒ New segment AD = 5 units + 5 units

⇒ New segment AD = 10 units

Answer:

Step-by-step explanation:

f(x) = cx + d

For the first equation

f(50) = 27,000

Substitute the value of x that's 50 into the expression

That's

50c + d = 27,000

For the second equation

f(100) = 38,000

Substitute the value of x that's 100 into the expression

We have

100c + d = 38,000

Subtract the first equation from the second one to eliminate d

That's

100c - 50c + d - d = 38,000 - 27,000

50c = 11,000

Divide both sides by 50

We have the final answer as
