Given f (x) = 3x - 8 find x if f(x) = -14​

Answer:

[See Below]

Step-by-step explanation:

✦ First change the improper fractions to decimals:

  ✧ ⁵⁄₄ = 1.25

  ✧ -⁹⁄₅ = -1.8

✦ Then divide:

  ✧ 1.25 ÷ -1.8 = -0.69

So x would be -0.69 in decimal form.

On January 3, the high temperature in Anchorage, Alaska, was −24∘F. That same day, the high temperature in Minneapolis, Minnesota, was −9∘F. Since, temperature is of interval scale, the difference between the temperature in Anchorage and the temperature in Minneapolis is of 15 degrees.

There are four scales of measurement. They are : nominal, ordinal, interval and ratio scale. Nominal and ordinal scales are for categorical data. Whereas, interval and ratio scale are for numerical data.

Interval scale only allows arithmetic operation addition and subtraction, but not multiplication and division.

Given in the question,

temperature of Anchorage, Alaska = −24∘F

temperature of Minneapolis, Minnesota =  −9∘F

difference in the two temperature =  −9∘F - ( −24∘F) = -9 + 24 = 15°F

Question :

There are 3 different cheeses at the deli. Yasuko buys Three-fourths of a pound of each. There are also 4 different meats. She buys One-half of a pound of each. How much total meat and cheese did Yasuko buy at the deli? a) One-fourth pounds

b) 2 and one-fourth pounds

c) 4 and one-fourth pounds

d) 4 and one-half pounds

Answer:

c) 4 and one-fourth pounds

Step-by-step explanation:

From the question:

There are 3 different cheeses at the deli. Yasuko buys Three-fourths of a pound of each.

Total pounds of cheese = 3 × (3/4)

= 9/4 pounds of cheese

There are also 4 different meats. She buys One-half of a pound of each.

Total pounds of meats she bought = 4 × (1/2)

= 4/2 pounds of meat

The total pounds of total meat and cheese did Yasuko bought at the deli =

= 9/4 pounds of cheese + 4/2 pounds of meat

L.C.M = 4

= 9 × 1 + 4 × 2/4

= 9 + 8/4

= 17/4

= 4 1/4 pounds

In words is 4 and one-fourth pounds

Answer:

y= -2x + 7

Step-by-step explanation:

So in slope intercept y will always equal something so you start with

y= mx + b

m = slope and b = y-intercept

so in this case it would first be

y = -2x + b

and then since we have the point it passes through (-4,7) we know that the line passes through the y axis at 7 hence the y value is 7.

so you finally get

y=-2x+7

The equation of line passes through the point (-4, 7) will be;

⇒ y = - 2x - 1

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The point on the line are (-4, 7).

And, The slope of the line is,

⇒ m = - 2

Now,

Since, The equation of line passes through the point (- 4, 7).

And, Slope of the line is,

m = - 2

Thus, The equation of line with slope - 2 is,

⇒ y - 7 = - 2 (x - (-4))

⇒ y - 7 = - 2 (x + 4)

⇒ y - 7 = - 2x - 8

⇒ y = - 2x - 8 + 7

⇒ y = - 2x - 1

Therefore, The equation of line passes through the point (-4, 7) will be;

⇒ y = - 2x - 1

Answer:

  39°

Step-by-step explanation:

It is the same measure as the one labeled 6x-9, since these are vertical angles.

  4x +7 = 6x -9

  16 = 2x . . . . . . . . add 9-4x

  8 = x

  4x+7 = 4(8) +7 = 39

The angle is 39°.

Answer: Symmetric property of equality

This is the idea that if x = y, then y = x. We can swap the left and right sides of an equation, and still mean the same thing. The same applies to congruences as well.

Answer:

The answer is below

Step-by-step explanation:

a) Natalie basic salary is $300 per week. She is paid a commission of 30% of her total sales for the week. Therefore her total weekly salary per week is given by:

Total weekly salary = Basic salary + Commissions

If Natalie makes $225 in sales, her commission = 30% of $225 = 0.3 × $225 = $67.5

Total weekly salary = Basic salary + Commissions = $300 + $67.5

Total weekly salary = $367.5

b) If Natalie makes $x in sales, her commission = 30% of $x = 0.3 × $x = $0.3x

Total weekly salary = Basic salary + Commissions = $300 + $0.3x

Total weekly salary = $(300 + 0.3x)

Answer:

Step-by-step explanation:

The average speed is defined as the total distance traveled divided by the total time taken.

from A to B

distance= 100 miles

speed= 50 mi/h

speed= distance/time

time= distance/speed

time= 100/50

time= 2 hours

from B to C

distance= 100 miles

speed= 70 mi/h

speed= distance/time

time= distance/speed

time= 100/70

time= 10/7 hours

Average speed= total distance/total time

total distance= 200 mile

total time= 2+10/7= (14+10)/7= 24/7

Average speed= 200/24/7

Average speed= 200*7/24

Average speed= 1400/24

Average speed= 58.3 mi/hour

Parallel lines have equal slopes, but different y intercepts.

For example, y = 2x+5 and y = 2x+7 are parallel lines with the same slope m = 2, but the y intercepts are different (5 and 7) to ensure we aren't talking about the same line.
