Solve the following equation for x.
5x + 15 = - 45
Answer:
-12
Step-by-step explanation:
5(-10)=-60
-60+15=
-45
Answer:
-12
Step-by-step explanation:
Reorder the terms:
15 + 5x = -45
Solving
15 + 5x = -45
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + 5x = -45 + -15
Combine like terms: 15 + -15 = 0
0 + 5x = -45 + -15
5x = -45 + -15
Combine like terms: -45 + -15 = -60
5x = -60
Divide each side by '5'.
x = -12 :)

Write an equation in slope-intercept form that is perpendicular to y = -7x + 3 and passing through (14.1).
Answer:
y = 1/7x -1
Step-by-step explanation:
1) Find the slope.
- In this case, the equation given is in simplest form so you can easily come to the conclusion that '-7' is the slope. But, since the math question wants a slope-intercept form in perpendicular form, the slope would actually be 1/7.
2) Use the point-slope form and substitute the values available. Then solve.
m (slope) = 1/7
(a, b) = (14, 1)
y - b = m(x - a)
y - 1 = 1/7(x - 14)
y - 1 = 1/7x - 2
y = 1/7x - 1
The result is your answer.
Hope this helped (please tell me if I made a mistake or if you have any confusion and I will resolve it under the comments) ^^
CAN U HELP I WILL GIVE 20 POINTS
Answer:
Your pay rate would be $7 per hour
Your friend's rate is $9 per hour
Step-by-step explanation:
To get the answer for your pay rate you'll have to divide 56/8 and then you'd get your number 7, so you get $7 dollars per hour.
To get the number for your friends pay rate you'd also do the same thing, divide. 36/4 gives you the number 9, so your friend gets $9 dollars per hour.

5-4x=23
What's the value of x and please show your work.
Answer:
x = 9/2 or 4.5
Step-by-step explanation:
5-4x=23 |-5
5-4x-5=23-5
-4x=18 |*(-1)
4x=18 | /2
2x=9 |/2
x=9/2 or 4.5
Answer:
x = 4.5
Step-by-step explanation:
Subtract 5 from BOTH sides to start with:
5-5 = 0 (5 cancels out on left side) 23-5 = 18
New Equation: -4x = 18
Divide BOTH sides by -4
4 cancels out (x is left) 18/4 = 4.5
New: x = 4.5
Solve for x/4+12=-12
Ed use 3 2/3 cups of peanut butter and 2 cups of powdered sugar to make 1 batch of peanut butter fudge. How much more peanut butter will Ed use than powdered sugar to make 3 batches of fudge?
Answer:
Ed will use 5 more peanut butter than powdered sugar to make 3 batches of fudge(11-6=5)
Step-by-step explanation:
3 2/3 cups of peanut butter (x)
2 cups of powdered sugar(y)
for every one batch you need 2 cups, and for 3 batches you need 6 cups of powdered sugar(2*3=6)
and for every batch you need 32/3 cups of peanut butter and for three batches you need (3 2/3 *3)= 11/3 *3=33/3=11 cups of peanut butter to make the fudge
Ed will use 5 more peanut butter than powdered sugar to make 3 batches of fudge(11-6=5)

Computer packages at an electronics store are priced $1,729.99, $2,249.99, $2,139.99, $1,979.99, and $999.99.
What is the range of the prices of the computer packages?
Answer:1250
Step-by-step explanation:
You take the highest number 2249.99 and subtract the lowest number 999.99 to get the range of 1250
The range of the prices of the computer packages is $1250.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Given,
Computer packages at an electronics store are priced $1,729.99, $2,249.99, $2,139.99, $1,979.99, and $999.99.
One thousand seven hundred and twenty nine point nine nine comma two thousands two hundred forty nine point nine nine comma two thousand one hundred thirty nine point nine nine comma one thousand nine hundred seventy nine point nine nine comma nine hundred ninety nine point nine nine.
Range is the difference between highest value minus lowest value.
Range=Highest value - Lowest value
Range=$2,249.99-$999.99.
Range=$1250
Hence, the range of the prices of the computer packages is $1250.

Answer:

Step-by-step explanation:
m over 8 minus 5 equal 12
Answer:
m = 136
Step-by-step explanation:
m/8 - 5 = 12
1. Add 5 on both sides
m/8 - 5 + 5 = 12 + 5
m/8 = 17
Multiply 8 on both sides since u are trying to isolate the variable
m/8 * 8 = 17*8
m = 136
Check
136/8 - 5 = 12
17 - 5 = 12
12 = 12
Hope it helped!
Step-by-step explanation:
[tex]\frac{m}{8}[/tex] - 5 = 12 : Original Problem
[tex]\frac{m}{8}[/tex] -5 +5 = 12 + 5 : Bringing the constants to one side
[tex]\frac{m}{8}[/tex] = 17 : Simplification
[tex]\frac{m}{8}[/tex]×8 = 17×8: Isolating the variable
m = 136 : The answer!!!
Checking the answer
[tex]\frac{136}{8}[/tex] -5 = 12 : Substitution
[tex]\frac{136}{8}[/tex] = 17 : Bringing constants to one side and simplification
136 = 17 × 8 : Isolating the answer
136 = 136 : Success!!!

HELP PLSSS Function g is a transformation x of f(x) = 2 ^ x Select all the true statements about the functions. (F-|F.2.4)
Answer:
its the second, not sure about 3
Step-by-step explanation:
2^x can never be negative
g is 2^x+4, which also can never be negative
neither have a y-intercept, so im not sure about three
but they have the same domain (-inf, inf), but not the same range, as g is always greater than 4, while f can be less than 4
and thus they don't have the same asymptote
both functions have an x-intercept: 1 for f(x), 5 for g(x)
so only the second choice is correct

-3a + 4 = -14
What the answer to this
Answer:
-6
Step-by-step explanation:
-3a + 4 = -14
-3a = -14 - 4
-3a = -18
a = -18 / 3
a = -6
Answer:
a = 6
Step-by-step explanation:
Step 1: Subtract 4 from both sides.
-3a + 4 - 4 = -14 - 4
+4 and -4 cancel out.
Step 2: Subtract 4 from -14 to get -18.
-3a = -18
Step 3: Divide both sides by -3.
a = -18/-3
Step 4: Divide -18 by -3 to get 6.
a = 6
Let's check our work by substituting a for 6.
-3(6) + 4 = -14
Multiply -3 by 6 to get -18.
-18 + 4 = -14
Add -18 and 4 to get -14.
-14 = -14
This is true, so a = 6.

Melanie earns $7 per hour when she
baby-sits. An equation for this relation
is w = 7h, where h represents the
number of hours and w represents
Melanie's wage in dollars.
a) Use the equation to create a table
of values.
b) In one week, Melanie earned $105.
How many hours did she baby-sit?
c) In one month, Melanie baby-sat for
24 h. How much did she earn
from baby-sitting in that month
Answer:
A) We know that she make $7 per hour, with this we can make a table:
1hr | $7
2hr | $14
3hr | $21
etc...
B) If in one week she earns $105 and 1w = 7h (1hr = $7) holds true, that means that we have to divide 105 by 7 which gives us 15hrs
C) If she baby-sat for 24hrs, we just have to multiply that by 7 and we get $168
