Answer:

a. x = 5/2

b. y = 16.5

c. z = 12

Step-by-step explanation:

Answer:

1) x = 2.5

b) y = 12.9

c) z = 12

d) 2.75 = w or 2[tex]\frac{3}{4}[/tex] = w

e) t = 4

Step-by-step explanation:

a)

2x = 5

divide both sides of the equation by 2

2x/2 = 5/2

x = 5/2

x = 2.5

b)

y + 1.8 = 14.7

subtract 1.8 from both sides of the equation

y + 1.8 - 1.8 = 14.7 - 1.8

y = 14.7 - 1.8

y = 12.9

c)

6 = 1/2z

divide both sides by 1/2 or multiply both sides by 2

6*2 = 1/2z * 2

6*2 = z

12 = z

d)

3.25 = 0.5 + w

subtract 0.5 from both sides of the equation

3.25 - 0.5 = 0.5 + 2 - 0.5

3.25 - 0.5 = w

2.75 = w

or

2[tex]\frac{3}{4}[/tex] = w

e)

2.5t = 10

t = 10/2.5

t = 4

Answer:

Measure of LKJ is 64

Step-by-step explanation:

Here, we want to find the measure of angle LKJ

mathematically, we know that a bisector line divides an angle into 2

Since one of the divided angle is 32

The other side too will be 32

Thus, the missing value would be;

32 + 32 = 64

The extra miles the pilot was forced to fly, found using Pythagorean Theorem was 16 miles. The correct option is therefore;

C. 16 mi

Pythagorean theorem can be stated as follows; The square of the length of the hypotenuse side of a right triangle is equivalent to the sum of the square of the lengths of the other two sides.

The direction the pilot planned initially = A southeast course

The direction the storm forced the pilot to travel = 32 miles south then 24 miles east

The number of extra miles the pilot is forced to fly = Required

Taking the original path as a straight line, and the destination arrived at being that of the new destination, we get by using Pythagoras Theorem

The new distance can be obtained by the scalar addition of the individual distances as follows;

d₂ = 32 + 24 = 56

The number of extra miles, Δd, is therefore;

Which indicates that we have;

im so so so sorry, but i dont know(possibly because im only in 7th grade with a sucky teacher)

Step-by-step explanation:

The answer is y(10° ) = -5351.5

A quadratic equation is a second-order polynomial equation in a single variable, x.

To write a quadratic relationship, consider the first three points: let it be A (0,70), B (1,69.7), and C (2,69.1).

To find the constant value, we substitute the first point in the quadratic function.

i.e   [tex]y=ax^{2} +bx+c[/tex]

At point A,  the equation becomes

y=0+0+c=70

i.e c=70

At point B, the equation becomes

a+b=69.7

At point C, the equation becomes

4a+2b=69.1

By solving the two equations above, we get the values of a and b.

a=-35.15 and b=104.85

Then the quadratic relationship becomes

[tex]y=-35.15x^{2} +104.85x+70[/tex]

At 11:00 A.M, the temperature becomes

y(10°) =-35.15(14*14) + 104.85(14)+70

y(10°)=-5351.5

The predicted temperature at 11.00 A.M is given by,  y(10°)=-5351.5

Step-by-step explanation:

Answer: The equation in slope-intercept form is y=2x-11

Step-by-step explanation: Slope-intercept is y=mx+b where m is the slope and b is the y-intercept. To find the slope, you find the difference between the y values divided by the difference between the x values. -5-(-9) = 4, and 3-1 is 2. 4/2 is 2, so m = 2. Since the slope is 2, it states for every x you move on the right you move 2 up. But we are trying to get the y-intercept, so x = 0. We are subtracting 1 in our x value, so we move 2 downwards. We subtract 2 from -9 which gives us -11, which is our y-intercept.

Hope this helps!
