⟹Answer:
[tex]x = -10[/tex]
⟹Step-by-step explanation:
Lets Solve!
⟹The first thing we must do is define our variables. Lets look at the problem again:
"The sum of a number and 7 is multiplied by 4. The result is equal to -12."
We can make x the number that is being added to 7.
The sum of x and 7 is multiplied by 4. This expression equals -12.
[tex]4(x+7) = -12[/tex]
⟹Now we use distribute 4 amongst (x+7)
[tex]4(x+7) = -12[/tex]
[tex]4x+28 = -12[/tex]
Next we subtract 28 from both sides.
[tex]4x+28 = -12[/tex]
[tex]4x = -40[/tex]
Last we divide 4 on both sides.
[tex]\frac{4x}{4} = \frac{-40}{4}[/tex]
➧ [tex]x = -10[/tex]

Step-by-step explanation:
please help me this question
====================================================
Work Shown:
r = radius = 7 cm
C = circumference of a full circle
C = 2*pi*r
C = 2*pi*7
C = 14*pi
C = 43.9822971502571 approximately
C = 43.9823
If we have a circle of radius 7, then the distance around the full circle is roughly 43.9823 cm.
Divide this over 2 to get the distance around half the circle
C/2 = 43.9823/2
C/2 = 21.99115
C/2 = 22 cm
This takes care of the curved portion. The straight portion is 2r = 2*7 = 14 cm which adds on to get 22+14 = 36 cm
Answer:
option b 36cm
Step-by-step explanation:
perimeter if the wire = diameter length + 0.5(2piradius) = 7+7+pi(7) = 35.991 cm = 36cm

Another name for the slope of a linear function is _________.
A. Average Rate of Change
B. Conjecture
C. First Differences
D. Polynomial
Answer:
A. Average Rate of Change
Step-by-step explanation:
lines from two points ( point slope form )
Answer:1
Step-by-step explanation:
to find the slop you have to use the formula m=y2-y1/x2-x1 but before you do that you have to label them like the first points (-8,-5) is (x1,y1) the the other points are (5,-8) which are (x2,y2) put them in a formula like M=y2-y1/x2-x1 which you get +1 as they answer.
Answer:
Step-by-step explanation:
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )
(- 8, - 5)
(5, - 8)
m = [tex]\frac{-5+8}{- 8-5}[/tex] = [tex]-\frac{3}{13}[/tex]
y + 8 = [tex]-\frac{3}{13}[/tex] ( x - 5 )
y = [tex]-\frac{3}{13}[/tex] ( x - 5 ) - 8

Abby that she needed to boil 3 cups of water but she actually needed to boil 5 cups of water what was her percent error
Answer:
40%
Step-by-step explanation:
Use the percent error formula:
percent error = (|accepted value – experimental value| / accepted value) x 100
Plug in the values and solve:
(|5 - 3| / 5) x 100
(2 / 5) x 100
= 40
So, the percent error is 40%

Answer:
x ≤ -11.25 or x > -8.75
Step-by-step explanation:
The graph here shows a disjunction compound inequality, in which either of the statements is true. That is for the compound inequality to be true, either one or the other statement is true. The word "OR" is used in stating this inequality.
On the graph, the directed line to our left has a full circle which starts at -11.25.
This means x ≤ -11.25.
The other directed line to our right has an empty circle, and starts at -8.75.
This means x > -8.75.
✅The compound inequality representing the graph will be written as:
x ≤ -11.25 or x > -8.75
Is 16-2x=-8+4(x-3) a infinite solution
Answer:
No it's one solution
Step-by-step explanation:
16-2x=-8+4(x-3)
16-2x=4x-20
subtract 16 from both sides = -2x=4x-36
subtract 4x from both sides = -6x=-36
divide both sides by -6
x=6

Answer:
y=3/5x-4
Step-by-step explanation:
Answer:
y = 3/5x - 4
Step-by-step explanation:
Usually, I always look for the y intercept first! This one is -4, since that's where the line hits the y axis. From that point, you would use RISE/RUN to find the slope, and in this case, it's 3/5 !!
I really hope this helps!!

Write the equation of the line passing through the points (44,6) and (-4,-6)
Answer:
Y = 1/4x - 5
Step-by-step explanation:
Slope (m = y2-y1 / x2-x1) is 1/4 and using one point substituting it instead of x and y you get y - intercept of -5.

PLEASE ANSWER THE QUESTION CORRECTLY!!
Answer:
y = -11
Step-by-step explanation:
Equation formula: y = mx + b
y = y-point
mx = slope
b = y-int
The equation has no slope since it's a straight line so the equation is y = -11
y = 0 + (-11)
y = -11

How do you subtract decimals and whole numbers again? My brain just fell asleep XD. Do you put the whole number before the decimal point, or do you ignore the decimal point completely? The equation is 18.5 - 16 if it helps you understand the question.
I dont understand what you are asking.
