What is the slope of a line parallel to the line whose equation is 22 - y = 7. Fully
reduce your answer.
Answer:
The slope of the parallel line is 2
Step-by-step explanation:
Parallel lines have equal slopes, so for this question you need to re-format the equation to match a y=mx+b format (slope-intercept form).
2x -y = 7 | Subtract 2x from both sides
-y = 7 + 2x | Multiply by negative one to make y even
y = 7 + 2x | Rearrange the equation to match the formula
y = 2x +7 | 2 is your slope for both parallel lines!

What does x equal?
Answer:
3x+7=10x-22
We simplify the equation to the form, which is simple to understand
3x+7=10x-22
We move all terms containing x to the left and all other terms to the right.
+3x-10x=-22-7
We simplify left and right side of the equation.
-7x=-29
We divide both sides of the equation by -7 to get x.
x=4.14285714286
Answer:
x=15
Step-by-step explanation:
(10x-22)+(3x+7)=180

How do I rewrite this number in scientific notation 54.8×103
Answer:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Step-by-step explanation:
You move right 2 units and left 10 units. You end at (-5, -1). Where did you start?
Answer:
(-13,-1)
Step-by-step explanation:
Moving right means moving positively on the x-axis
Moving left means moving negatively on the x-axis
Follow the equation backwards using the x-coordinate:
Move left 10 units-- -5-10 = -15
Move right 2 units-- -15+2 = -13
Since the y-coordinate did not change, the point you started at is (-13,-1)

Beth bought 35¢ stamps and 15¢ stamps at the post office. If she purchased 60 stamps at a cost of $17, how many of each kind did she buy?
Answer:
She buys 20 Stamps of $0.15 and 40 Stamps of $0.35.
Step-by-step explanation:
40 x 0.35 = 14
20 x 0.15 = 3
$14 + $3 = $17
40 ($0.35) + 20 (0.15) = 60 stamps

Given that pentagon ABCDE ≈ pentagon FGHIJ, find the measure of angle 1.
A. 99
B. 100
C. 121
D. Cannot be determined
the given angle of 1 is 100
The measure of ∠1 is equivalent to 100°.
What is the difference between upward, downward, leftwards and rightwards translation?Upward translation : [k] units = When the upward translation take's place then, each point will have its y - coordinate shifted upwards by +k units.Downward translation : [k] units = When the downward translation will take place then, each point will have its y - coordinate shifted downwards by -k units.Leftward Translation : [k] units = When the leftward translation will take place then, each point will have its x - coordinate shifted by -k units to the left.Rightward Translation : [k] units = When the rightward translation will take place then, each point will have its x - coordinate shifted by +k units to the right.Given is that pentagon ABCDE ≈ pentagon FGHIJ.
Since the pentagons are similar, we can say that the corresponding angles will be equal. So, we can write -
∠1 = 100°
Therefore, the measure of ∠1 is equivalent to 100°.

In the diagram below,Ab and De bisect each other.If f is the midpoint dc, AB=20 and De=12, find the value of FC+CB.Show how you arrived at your answer.
Answer:
13
Step-by-step explanation:
AB = 20
DE =12
Since AB and DE bisect each other, therefore:
AC = CB = ½(AB)
AC = CB = ½(20)
AC = CB = 10
Also,
DC = CE = ½(DE)
DC = CE = ½(12)
DC = CE = 6
Since F is the midpoint of DC, therefore:
FC = ½(DC)
FC = ½(6)
FC = 3
Find the value of FC + CB. Plug in the values of FC and CB:
3 + 10 = 13
NEED HELP ASAP!! which function has a range of y is greater than or equal to 0
Answer:
c
Step-by-step explanation:
The third function has a range of y that is greater than or equal to 0.
What is a function?A function is a kind of rule that, for one input, gives you one output.
For the first function, it contains negative values for y, so it was eliminated.
The second function did not start from zero, so it was eliminated.
The third function obeys the given condition, but the last function contains negative values for y.
Hence, the third function satisfies the condition that y is greater than or equal to 0.

A rectangular prism has a square base with side length s units. It also has the curious property that the numerical value of the sum of its edge lengths (in units) is equal to the numerical value of its surface area (in square units).
If one edge of the prism has length 8 units and s 6= 8, then s can be written in the form a + √b, where a and b are integers. Find a + b.
You need 660 mL of a 80% alcohol solution. On hand, you have a 40% alcohol mixture. How much of the 40%
alcohol mixture and pure alcohol will you need to obtain the desired solution?
You will need
mL of the 40% solution
and
mL of pure alcohol.
Submit Question
Let a be the amount of 40% solution and b be the amount of pure alcohol that you will use.
You want to end up with a volume of 660 mL, so
a + b = 660
For each mL of solution used, the 40% solution would contribute 0.4 mL of alcohol, and the pure alcohol will contribute 1 mL of alcohol. In the desired solution, you want a concentration of 80% alcohol, so that it contains 0.8 • 660 mL = 528 mL of alcohol, and
0.4a + b = 528
Solve the system of equations above. Subtracting the second from the first eliminates b and lets us solve for a :
(a + b) - (0.4a + b) = 660 - 528
0.6a = 132
a = 220
Then
220 + b = 660
b = 440
So you will need 220 mL of the 40% solution and 440 mL of pure alcohol.

At the market, 8 batteries cost $10,
How much do 6 batteries cost?
Answer:
$7.50
Step-by-step explanation:
You can use proportions to find that 8/10 = 6/x
then you can multiply 10 by 6 and divide the result by 8 to get the answer.
You can also divide 10 by 8 to get 1.25 and multiply it by 6, as 10 divided by 8 gives you the unit rate, or the price of each battery. Then you multiply it by 6 to get 7.5, or the cost of 6 batteries.

QUADRATIC EQUATION – WORD PROBLEMS
Fatima got 16 marks more than Zahra in Math test. The product of their mark is 1380. Find their marks.
The answer 30 ,46
I just need the steps
Answer:
Fatima's points = 46
Zahra's points = 30
Step-by-step explanation:
Let's give names to the unknowns (the number of points each one got)
Fatima's points = y
Zahra's points = x
Now create the equations given by the info they provide:
"Fatima got 16 marks more than Zahra"
y = x + 16
"The product of their mark is 1380."
x * y = 1380
Now use the first equation as substitution for "y" in the second equation:
x * (x + 16) = 1380
reduce the expression:
x^2 + 16 x = 1380
x^2 + 16 x - 1380= 0
Solve using quadratic formula:
[tex]x=\frac{-16+/- \sqrt{16^2+4(1380)} }{2} \\x=\frac{-16+/- \sqrt{5776} }{2} \\x=-8+/- 38\\x = 30\,\,\,or\,\,\,x=-46[/tex]
we pick 30 since the scores from a test must be larger than zero.
Now we use the first equation to solve for the other variable;
y = 30 + 16 = 46
then x = 30 and y = 46
