the angles you have to find are vertical angles to the equations that are given. a vertical angle is an angle that is directly across from another.

angle 1 is equal to 4x+10

angle 2 is equal to 8x-25

since this is a transversal,

4x+10=8x-25

then just solve for x.

x= 8.75

then substitute 8.75 wherever you see x.

4(8.75)+10 = 45
8(8.75)-25= 45

going back to the vertical angle rule, both angle 1 and 2 are equal to 45°

Form an equation in x and solve it.​

Answers

Answer:

x= 8

Step-by-step explanation:

x^2 = 6x+16

TAKE RHS OVER TO LHS TO EQUATE IT TO 0

x^2 - 6x - 16 = 0

FACTORISE

(x-8)(x+2) =0

Therefore

x-8= 0 or x+2= 0

x= 8 or x= - 2

Sub and see which works

8^2 = 6(8) + 16

64= 64

-2^2 = 6(-2) + 16

-4= 4

So the answer must be

x= 8

Answer: b =50°

Step-by-step explanation:

The angles on a straight line =180°

180° = 50°+90°+b

180°-50°-90°=b

50° = b

Answer:

Step-by-step explanation:

∠b + ∠a + 50° = 180°

∠b + ∠90 + 50° = 180°

∠b = 180° - 90° - 50° = 40°

After driving for 2 hours, Juan is 110 miles from his home. After driving 5 hours, he is 275 miles from his home. What is his average rate of change?

Answers

Answer:

392

Step-by-step explanation:

The average rate of change will be "55 m/h".

According to the question,

→ After 2 hours (t₁),

Juan is 110 miles (d₁) from his home.

→ After 5 hours (t₂),

Juan is 275 miles (d₂) from his home.

→ The average rate of change will be:

= [tex]\frac{d_1+d_2}{t_1+t_2}[/tex]

By substituting the values, we get

= [tex]\frac{110+275}{2+5}[/tex]

= [tex]\frac{385}{7}[/tex]

= [tex]55 \ m/h[/tex]

Thus the above is the right solution.

Slope intercept form looks like this: y = mx + b where m is the slope and b is the y intercept. An example of a line in slope intercept form is y = 5x + 3.

The important thing to realize is that y is alone on one side. It doesn’t have a coefficient (number in front of variable) and is positive. X and the constant (in the example above the constant is 3) are on the other side of the equation.

To put 4y - 4x = -32 into slope intercept form, first add 4x to both sides

4y = 4x - 32

Divide each side by 4 (so y is alone)

y = x - 8

What is parallelogram?

A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.

Given that, a parallelogram with one base 11, height 10 units and area 60 sq units.

We know that, area of a parallelogram = base x height

Therefore,

base x 10 = 60

base = 60 / 10

base = 6

Hence, the missing base is 6.
