f(-5) = 17f(7) = 19====================================
Work Shown:
Plug in x = -5. Use PEMDAS to simplify
f(x) = |3x-2|
f(-5) = |3(-5)-2| ... replace every x with -5
f(-5) = |-15-2|
f(-5) = |-17|
f(-5) = 17
---------------------
Repeat for x = 7
f(x) = |3x-2|
f(7) = |3*7-2| ... replace every x with 7
f(7) = |21-2|
f(7) = |19|
f(7) = 19
find the value of x. PLEASE HELP

2x+108 = 180
2x+108-108 = 180-108
2x = 72
2x/2 = 72/2
x = 36
-------
Notes:
The reason 2x and 108 add to 180 is because they form a straight angleIn step 2 above, I subtracted 108 from both sidesIn the second to last step above, I divided both sides by 2.The general steps to solving any equation is to follow PEMDAS in reverse to isolate the variable.Given : There is a line . It is divided into two parts by another line such that it forms two angles on two sides of the angle which are 2x° and 108° .
To Find : The value of x .
Solution : Given that the two angles are 2x and 108° . So , we know that the measure of a straight line is 180° . So the sum of the two angles will be also equal to 180°. That is ;
[tex]\large\boxed{\red{\bf \angle 1 + \angle 2= 180^{\circ}}}[/tex]
Where [tex]\angle[/tex]1 and [tex]\angle[/tex]2 are two angles .⇒ 2x° + 108° = 180° .
⇒ 2x° = 180° - 108° .
⇒2x° = 72°.
⇒ x =[tex]\sf \dfrac{72}{2}[/tex]
⇒ x = 36° .
Hence the value of x is 36° .

Mrs. Chip bought 2 sheets and a blanket and paid $41. Mrs. Dale bought a sheet and 4 blankets and paid $80.
Answer:
Sheet = $12Blanket = $17Step-by-step explanation:
Let the cost of a sheet be s and cost of a blanket be b
2s + b = 41s + 4b = 80From the first equation we get:
b = 41 - 2sSubstitute in the second equation
s + 4*(41 - 2s) = 80s + 164 - 8s = 807s = 84s = 12Then
b = 41- 2*12 = 17Lin is interested in how many of her classmates watch her favorite TV show, so she starts asking around at lunch. She gets the following responses: 4 YES and 10 NO. If she ask one more random classmate, do you think they will say "YES" or " NO"?
Answer:
They will probably say NO
Step-by-step explanation:
Add to find the total number of response.
10 + 4 = 14
Find the probability of someone saying yes or no.
4 / 14 ≈ 0.29 or 29%
10 / 14 ≈ 0.71 or 71%
As you can see, saying NO is more likely than saying YES.
Best of Luck!
Solve the equation
(1/2)-sinx=1
Answer: #2. sin x (sin x + 1) = 0
sin x = 0 or sin x + 1 = 0
sin x = 0 or sin x = -1
Step-by-step explanation:
the value of x will be x = 210° and 330° for the given expression (1/2)-sinx=1.
What is an expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.
Given a equation (1/2)- sin x = 1
Simplifying the given expression
=> (1/2)- sin x = 1
subtract 1/2 on both sides
=> -sin x = 1/2
=> sin x = -1/2
=> x = 210° and 330°
For all x = 0 to 360°

An angle measures 70.2° more than the measure of its complementary angle. What is the measure of each angle?
A complementary angle of another angle is the angle that when you add it to that angle, you get 90 degrees.
For example, we have angle A. When we add the complementary angle of angle A, you get 90 degrees. :)
So, what we can do for this problem is create an equation! :)
x + 70.2° = "an angle"
x = complementary angle
Notice: I put the 70.2° to show the difference between the complementary angle and the angle itself.
Now, we can make an equation!
(x + 70.2°) + x = 90
2x = 19.8
x = 19.8/2
x = 9.9 degrees
One angle is 9.9 degrees, and the other angle is x + 70.2 = 9.9 + 70.2 = 80.1 degrees. We can see that when we add 9.9 and 80.1 we get 90 degrees, and when you minus 9.9 from 80.1, you get 70.2. :)

The poetry club had its first bake sale and they made 79.35 dollars. The club members are planning to have 4 more bake sales. Leslie said if we make the same amount at each bake sale we will earn 3,976.50 dollars. Peggy said no way we will earn 396.75 after bake sales. Use estimation to help Peggy explain why Leslie reasoning is incorrect.
Answer:
Peggy is correct, their total bakes sale = $396.75
Step-by-step explanation:
Using estimation to help Peggy explain why Leslie reasoning is incorrect.
From the question we can see that:
First bake sale they made = $79.35
4 more bake sales making the same amount = 4 × $79.35
The total amount they would make from the bake sales =
$79.35 + (4 × $79.35)
= $396.75
Peggy was right. Leslie's reasoning was incorrect.

Complete the sentence with the phrase that makes the proof statement true. Segment PR is perpendicular to segment QS. Angle QRP is a right angle A. by the definition of perpendicular. B. because angle Q is congruent to angle S. C. by the Reflexive Property of Equality. D. because PQR is an isosceles triangle.
Answer:
A. by the definition of perpendicular.
Explanation:
Indeed, in geometry, for lines to be termed as been perpendicular, it means that two lines met at a right angle (90 degrees).
From the attached image we could see that Segment PR is perpendicular to segment QS as it touches or meets with segment QS which follows the definition of perpendicular. Also, Angle QRP is a right angle because it is exactly 90 degrees.

One yardstick for measuring how steadily—if slowly—athletic performance has improved is the mile run. In 1958, the local record for the running of a certain distance was 3 minutes, 59.3 seconds, or 239.3 seconds. In the half-century since then, the record has decreased by 0.5 seconds per year.
Answer:
They will hit 180 seconds in 118.6 year
Step-by-step explanation:
Let M be the record for the mile (in seconds)
Let x be the year after 1958
So, x=(year)-19548
We are given that In the half-century since then, the record has decreased by 0.5 seconds per year
So, slope = m = 0.5
Now we will use point slope form
y = mx+c
So, we can express M as,
[tex]M=239.3-0.5 \times x[/tex]
Now we are supposed to find when they will hit 180 seconds
Substitute M = 180 in equation
180=239.3-0.5x
x=118.6
So, they will hit 180 seconds in 118.6 year
