Eva is solving the equation 4(x+3/2)=8. She says, “I can subtract 3/2 from each side to get and then divide by 4 to get x=13/8. Dakota says, “I think you made a mistake.” How can Dakota know for sure that Eva’s solution is incorrect?

Please help my mom is gonna be mad at me if i can't get this question right

Step-by-step explanation:

436.2 / 6 = 72.7

Answer:

m = 35 , n = 110

Step-by-step explanation:

the opposite angles of a parallelogram are congruent , then

2m = 70 ( divide both sides by 2 )

m = 35

consecutive angles are supplementary, that is sum to 180° , then

n + 70 = 180 ( subtract 70 from both sides )

n = 110

Solution:

We know that:

This means that:

Divide 2 both sides to find m:

We can see that two angles measuring 70° and n° are a linear pair.

Answer:

c > 1

Step-by-step explanation:

Given equation: [tex]x^2-2x+c=0[/tex]

General form of quadratic equation: [tex]ax^2+bx+c=0[/tex]

We can use the discriminant to determine the value of c for which the equation has no real roots.

[tex]b^2-4ac < 0\implies \textsf{no real roots}[/tex]

From the given equation:

Inputting these values into the discriminant formula:

[tex]\implies (-2)^2-4(1)(c) < 0[/tex]

[tex]\implies 4-4c < 0[/tex]

[tex]\implies 4 < 4c[/tex]

[tex]\implies 1 < c[/tex]

[tex]\implies c > 1[/tex]

Here

Discriminant must be less than 0

[tex]\\ \rm\Rrightarrow b^2-4ac<0[/tex]

[tex]\\ \rm\Rrightarrow (-2)^2-4(1)(c<0[/tex]

[tex]\\ \rm\Rrightarrow 4-4c<0[/tex]

[tex]\\ \rm\Rrightarrow 4(1-c)<0[/tex]

[tex]\\ \rm\Rrightarrow 1-c<0[/tex]

Answer:

  8 units

Step-by-step explanation:

Points (2, 5) and (10, 5) have the same y-coordinate, so lie on the horizontal line y = 5. The distance between the points is the difference of their x-coordinates:

  10 -2 = 8

The points are 8 units apart.

B. I don't Know

Step-by-step explanation:

Answer:

For this case we can model the problem as a rectangle triangle.

 We know:

 Length of the hypotenuse

 Angle between the base of the triangle and the hypotenuse.

 We want to know:

 Length of the base.

 For this we use the following trigonometric relationship:

 cos (15) = \frac{x}{500}cos(15)=500x

 Clearing x we have:

 x = 500 * cos (15) x = 482.96x=500∗cos(15)x=482.96

 Rounding to the nearest tenth of a meter:

 x = 483.0 mx=483.0m

 Answer:

 The horizontal distance she has covered is:

 x = 483.0 mx=483.0m

Answer:

1.[tex]y=2x+4[/tex]
2.[tex]y=1x+3[/tex]

Step-by-step explanation:

Given the following questions:

Question one:

Point A = (-1, 2) = (x1, y2)
m = 2

To find the answer we will use the formula to find the slope intercept, substitute the values and then solve for b.

[tex]y=mx+b[/tex]
[tex]m=2[/tex]
[tex]x=-1[/tex]
[tex]y=2[/tex]
[tex]2=2(-1)+b[/tex]
[tex]2\times-1=-2[/tex]
[tex]2=-2+b[/tex]
[tex]-2+2=0[/tex]
[tex]2+2=4[/tex]
[tex]4=b[/tex]
[tex]b=4[/tex]
[tex]y=2x+4[/tex]

The slope intercept form of the line that passes through (-1, 2) and has a slope of 2 is "y = 2x + 4."

Question two:

Point A = (-1, 2) = (x1, y1)
Point B = (2, 5) = (x2, y2)

To find the slope intercept form we must first find the slope using the formula to calculate slope or rise over run.

[tex]m=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{5-2}{2--1}=\frac{3}{3}[/tex]
[tex]3\div3=1[/tex]
[tex]m=1[/tex]

Now that we have the slope, we will use the formula for slope intercept, substitute the values, then solve for b.

[tex]y=mx+b[/tex]
[tex]m=1[/tex]
[tex]y=2[/tex]
[tex]x=-1[/tex]
[tex]2=1(-1)+b[/tex]
[tex]1\times-1=-1[/tex]
[tex]2=-1+b[/tex]
[tex]-1+1=0[/tex]
[tex]2+1=3[/tex]
[tex]3=b[/tex]
[tex]b=1[/tex]
[tex]y=1x+3[/tex]

The line that passes through the points (4, -2) and (2, 5) in slope intercept form is indeed "y = 1x + 3."

Hope this helps.

Step-by-step explanation:

Hopefully this helps you,
So if A= 70 degrees, C will also 70 degrees.
The parallelogram will always equal 360 degrees, so 70(2) = 140.
Then 360 - 140 = 220.
Then divide 220 by 2, so 220/2 = 110.
Therefore angles B and D are 110 degrees.
So your answer,
C = 70 degrees
B and D = 110 degrees

Step-by-step explanation:

x²+4x=8

rearrange

x² + 4x - 8 = 0

half of 4 is 2

so

x² + 4x + 2² - 2² - 8 = 0

do x² + 4x + 2²

multiplies to give 4 adds to give 4

2+ 2

(x + 2)²

(x + 2)² - 2² - 8

(x + 2)² - 4 - 8

(x + 2)² - 12

(x + 2 + √12) (x + 2 - √12)

√12 = √4 * √3 = 2 √3

(x + 2 + 2√3) (x + 2 - 2√3)

Answer:

Step-by-step explanation:

1. x-9=-17-simplifies to a single solution-one solution

2.x+4=4+x-same thing on each side-infinite solutions

3. 0.4x=0.4x+2-same variable coefficient plus a number-no solutions

4. 5x=5x-3-same as above-no solutions

5. 5x=2-variable on one side, constant on another-one solution

6. x-5=x-5-same thing on each side-infinite solutions

7.3x=3x-same thing as above-infinite solutions

8.8x-10=8x-same coefficient for each variable plus a constant-no solutions

Answer:

One solution:

x + 9 = -17

5x = 10

No solution:

0.4x = 0.4x +2

5x = 5x - 3

8x - 10 = 8x

Infinite solutions:

x + 4 = 4 + x

x - 5 = x - 5

3x = 3x

Step-by-step explanation:

x + 9 = -17

  - 9     -9

x = -26 (one solution)

x + 4 = 4 + x

  - 4   - 4

x = x (infinite solutions)

0.4x = 0.4x +2

-0.4x  -0.4x

0 = 2 (no solution)

5x = 5x - 3

-5x  -5x

0 = -3 (no solution)

5x = 10

/5   /5

x = 5 (one solution)

x - 5 = x - 5

 + 5       + 5

x = x (infinite solutions)

3x = 3x (infinite solutions)

8x - 10 = 8x

    + 10  + 10

8x = 8x + 10

-8x   -8x

0 = 10 (no solution)

Steak burgers = $4.50

Fries = $2.25

Step-by-step explanation:

Steak burgers = x; fries = y

-2 (3x + 2y = $18)

3  (2x + 3y = $15.75)

-6x - 4y = -36

6x + 9y = 47.25

5y = 11.25

÷5    ÷5

y = $2.25

3x + 2y = 18

3x + 2( 2.25 ) = 18

3x + 4.5 = 18

Answer:

The tree is 28 feet in height.

Step-by-step explanation:

This is a proportion problem. You need to keep the height of the objects on one side of the ratios and the length of the shadows on the other.

74 / x = 102/39           Cross Multiply

102x = 74*39              The inches as a unit cancel out.

102x = 2886               Divide by 102

x = 2886/102

x = 28.29 feet

The bat will fit in the box if the length of the bat is less than the interior diagonal of the box

Julian's bat will not fit inside the box

From the complete question, the dimension of the box is:

32 in by 6 in by 8 in

Start by calculating the diagonal (d) of the base of the box using the following Pythagoras theorem

[tex]d^2 = 6^2 + 8^2[/tex]

Next, calculate the length of the interior diagonal of the box.

[tex]L = \sqrt{32^2 + d^2\\[/tex]

This gives

[tex]L = \sqrt{32^2 + 6^2 + 8^2}[/tex]

Evaluate

[tex]L = 33.53[/tex]

The length of the bat (34 inches) is greater than the interior diagonal of the box (33.53 inches)

Hence, the bat will not fit inside the box

Answer:

  34.6

Step-by-step explanation:

The perimeter of a plane geometric figure is the sum of its side lengths. This figure has two horizontal sides, so their length is easy to compute. It also has two diagonal sides, so the distance formula or Pythagorean theorem must be invoked to find their length.

The length of diagonal AC is ...

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((1 -6)² +(-5 -4)²) = √((-5)² +(-9)²) = √106 ≈ 10.3

The length of each horizontal segment can be found by counting grid squares or by finding the difference of x-coordinates.

  AB = 6 -(-1) = 6 +1 = 7

__

Two sides have length 10.3 and two sides have length 7, so the perimeter is ...

  P = 2(10.3 +7) = 34.6 . . . units
