I need help please!!!!

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:

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: 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

where is the question here n a graph ?????

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

sinΦ = 18/44

Φ= 24.15°

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:

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]

No, because people who are the same age can have different zip codes!!

I took a test with this question and got it correct!!

Step-by-step explanation:

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:

The negative solution = x = -4

Step-by-step explanation:

Let the number be = x

The square of number = x²

The difference between the square of a number and 28 = x²-28

Given that the difference of the square of a number and 28 is equal to three times that number.

Thus, the equation becomes

[tex]x^2-28=3x[/tex]

subtract 3x from both sides

[tex]x^2-28-3x=3x-3x[/tex]

[tex]x^2-3x-28=0[/tex]

[tex]\left(x+4\right)\left(x-7\right)=0[/tex]

[tex]x+4=0\quad \mathrm{or}\quad \:x-7=0[/tex]

[tex]x=-4,\:x=7[/tex]

Thus, the negative solution = x = -4

Answer:

hosta = 2 $,,, geranium = 5 $

Step-by-step explanation:

if we make two eq.

1) .... 54 = 2h + 10g

2) ...... 40 = 10h + 5g

if we multiply 1st by -5 it turns to

3) ..... -270 = -10h - 50g

cancel both 10h

add eq. .. becomes : -230 = -46g

g = 5

substitute in any find , that h = 2

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:

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:

X=56 Y=56

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.

Answer: 6, 4.5

Step-by-step explanation:

area of the whole figure

= (x + 1)(2x + 3)

= x(2x + 3) + 1(2x + 3)

= 2 {x}^{2} + 3x + 2x + 3

= (2x)^(2} + 5x + 3

area of the unshaded region

= x(2x)

= 2x²

area of the shaded region

= 2x² + 5x + 3 - 2x²

= (2x² - 2x² ) + 5x + 3

= 5x+ 3

THEREFORE,

THE AREA OF THE FRAME IS C. 5x + 3

Answer: Inverse variation

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: x=8

Step-by-step explanation: Solve for the x by simplifying both sides of the equation, then isolate the variable.

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]
