triangles must be-

Answer:

c. 3

Step-by-step explanation:

5 can only have factors like 10, 15. 4 is not it because 4x10 is 40 and it cant be 42 and then 9x5 is 45. Your welcome. Pls mark brainliest :)

Answer:

hi .................

Answer:

x= -5

Step-by-step explanation:

First get X alone by dividing both sides by -4.2

-4.2x=21

-4.2. -4.2

then you're left with X = -5

To verify your answers, multiply -5 by -4.2

Answer:

y = 5x + 14

Step-by-step explanation:

y represents the total money their parents give them. X represents the number of chores. 5 is the sum of 3 + 2 since Jack gets $3 for each chode while Bella gets $2 for each chore. 14 is the set amount of money the receive each week since 8 + 6 is 14.

Answer:

I hope this help you out!

Answer:

The width is - 4 the lengeth is - 7

Step-by-step explanation:

w*l = 28in²

w = ?

l = w+3

w=2

2+3 = 5

5*2 = 10

w = 3

3+3 = 6

6*3 = 18

w = 4

4+3 = 7

7*4 = 28

So,

W = 4 L = 7

Answer:

(a/b)^k=a^k/b^k

Step-by-step explanation:

Using the laws of exponents, we know that (a/b)^k=a^k/b^k.

I couldn't get it to format correctly so just know that the "/" are for the fraction signs and the "^" is for the exponent marking.

Answer:

a^k / b^k

Step-by-step explanation:

You have to use the properties of the powers.

Answer: 6, 4.5

Step-by-step explanation:

Answer:

C: (1, 2.5)

Step-by-step explanation:

The point is not exactly on 2 or 3 on the y axis. So it is at 2.5. and when you read a graph you need to look at it from x to y so it should be C: (1, 2.5).

Answer:

X=56 Y=56

Step-by-step explanation:

Answer:

x = 1[tex]\frac{1}{6}[/tex], y = 3[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

y = -2x + 6 --- Equation 1

y = 4x - 1 --- Equation 2

Since both (-2x + 6) and (4x - 1) have the same total, y, they are equal.

-2x + 6 = 4x - 1

Isolate the like terms.

6 + 1 = 4x + 2x

Evaluate like terms.

6x = 7

Find x.

x = [tex]\frac{7}{6}[/tex]

x = 1[tex]\frac{1}{6}[/tex]

Substitute x = [tex]\frac{7}{6}[/tex] into Equation 2:

y = 4x - 1

y = 4([tex]\frac{7}{6}[/tex]) - 1

  = 4[tex]\frac{2}{3}[/tex] - 1

y = 3[tex]\frac{2}{3}[/tex]

counting the grid spaces from any point for example R and going to the point R' (R prime) will give you the translation

Answer: Inverse variation

Answer:

$240

Step-by-step explanation:

40 x 5 = 200

40 x 6 = 240                  (basically just adding forty dollars)

Answer:

[tex]\theta=24^\circ[/tex]

Step-by-step explanation:

Trigonometry and Right Triangles:

The ratios of the sides of a right triangle are called trigonometric ratios. Any angle or side length can be calculated using the appropriate trigonometric ratio.

Please refer to the image below. The balloon is 100 feet high and the rope has a length of 250 feet. The right triangle formed allows us to apply a trigonometric ratio that relates the two given side lengths: the hypotenuse and the opposite leg to angle θ.

The sine ratio is defined as:

[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]

[tex]\displaystyle \sin\theta=\frac{100}{250}=0.4[/tex]

[tex]\displaystyle \sin\theta=0.4[/tex]

Calculating θ:

[tex]\theta=\arcsin 0.4[/tex]

[tex]\theta=23.6^\circ[/tex]

To the nearest degree:

[tex]\mathbf{\theta=24^\circ}[/tex]

Answer:

All real solutions

Step-by-step explanation:

5w - 15 < 5w + 20

subtract 5w from both sides

-15 < 20

since it is true and there are no variables left. all real solutions will make this true

Answer:

w < w + 7

Step-by-step explanation:

5w-15 < 5w+20

divide all by 5 =

w < w + 7

Answer:

x = 81/4

Step-by-step explanation:

multiply both sides by 4

4x + 15 = 96

subtract 15 from both sides

4x = 81

divide both sides by 4

x= 81/4

i hope that's right

Answer:

81/4

Answer:

  no

Step-by-step explanation:

When the second equation is put in standard form like the first equation is, then you can see they are different. They do not define the same line.

  3x +2y = 7

  x + y = 7 . . . . . second equation in standard form

Answer: Let's solve for x.

−x−y=6

Step 1: Add y to both sides.

−x−y+y=6+y

−x=y+6

Step 2: Divide both sides by -1.

−x

−1

=

y+6

−1

x=−y−6

Answer:

x=−y−6

Let's solve for x.

5x−7y=66

Step 1: Add 7y to both sides.

5x−7y+7y=66+7y

5x=7y+66

Step 2: Divide both sides by 5.

5x

Answer: Y=-5

Step-by-step explanation:

The reason is because if you look down the y axis from the origin you can see the location where the line crosses over the y axis in this case it was at (0,-5)

Answer:

-3/2

Step-by-step explanation:

Rise/run

You count down/up however many until the line hits another point, and then go across until it matches. So I counted down 3 squares and over 2, and since it is going down it is negative.

I hope this helps :)
