What’s the value of x

Answers

Answer:

16

Step-by-step explanation:

This is due to the rule that all shapes exterior angles add to 360.

Therefore 360 = 46 + 3x +62 + 4x + 47 + (180-83)

360 = 248 + 7x

7x = 112

x= 16

The equation of a line is y = 2x − 6. Find the slope and y-intercept of the line.

Answers

Answer:

Slope is 2 and y-int is -6

Step-by-step explanation:

y=mx+b

M is slope

B is y-int

Answer:

The slope is 2 and the y intercept would be -6

Step-by-step explanation:

y=mx+b where M would be the slope and b is the y intercept. Fill in the formula and there you have the slope and the y intercept. Good luck!

Find the equation of the line that is parallel to y = -7x + 2 and contains the point (-5,32)​

Answers

Answer:

Y=-7x-3

Step-by-step explanation:

Answer:

y = - 7x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 7x + 2 ← is in slope- intercept form

with slope m = - 7

Parallel lines have equal slopes, thus

y = - 7x + c ← is the partial equation

To find c substitute (- 5, 32) into the partial equation

32 = 35 + c ⇒ c = 32 - 35 = - 3

y = - 7x - 3 ← equation of parallel line

2) 5 gallons and lose 2/3 gallons per minute

2/3 gal/minute minutes) = 5 gallons

x = 5(3/2) = 15/2 = 7.5 minutes to drain the other 5 gallons

3) 10 gallons when full

That is 3 gallons more than the 7 gals there when Jada arrived.

Terrell wrote that 5 – 4.2 = 8. Which statement about his answer is true? CLEAR CHECK 8 is wrong because a number gets smaller, not larger, when you take 4.2 from it. 8 is right because 50 – 42 = 8. 8 is right because 4.2 + 8 = 5. 8 is wrong because you cannot subtract a decimal from a whole number.

Answers

Answer:

a) is wrong because a number gets smaller, not larger, when you take 4.2 from it

Step-by-step explanation:

Given

[tex]5 - 4.2 = 8[/tex]

Required

Determine which of the options is true

First, we need to solve for 5 - 4.2

[tex]5 - 4.2 = 0.8[/tex]

Compare this answer with Terell's answer (8)

We observe that: [tex]0.8 \neq 8[/tex]

This implies that; Terell is wrong

The two options that support the answer being wrong are (a) & (d)

Analyzing (a):

5 should get smaller when 4.2 is subtracted from it.

This isn't the case in Terell's solution.

Hence, (a) is true

Analyzing (d):

d is wrong because a decimal can be subtracted from a whole number

Hence, (a) answers the question
