Answer:
-7/5.
Step-by-step explanation:
Leave the denominators the same and subtract only the numerators. Since -3 is negative and 4 is a positive being subtracted, you get -7 as the numerator. So, it's -7/5.
Find the value of 9w + 1 given that -5w -5 = 5
Answer:
-17
Step-by-step explanation:
First, let's see what the value of w is, by solving -5w - 5 = 5.
-5w - 5 = 5 Add 5 on both sides.
-5w = 10 Divide -5 on both sides.
w = -2
Now, we know that w is equal to -2, let's plug it in to find the value.
9(-2) + 1 Distribute.
-18 + 1 Add.
-17

If 7m - 3 = 53. What is the value of 11m + 2?
Answer:
90.
Step-by-step explanation:
7m - 3 = 53
m would be 8 because 56 - 3 = 53.
11m + 2 equals 90 because 11 times 8 (8 is m) is 88, which added by two is 90.
What is the solution of the system of linear equations graphed below?
Answer: (1.125,-0.25)
Step-by-step explanation: The point that is the same for both equations is the point where they intersect. It appears from the graph to be around (1,0). We should confirm this by deriving the equation for each line and then solving them. Use the standard format: y = mx+b, where m is the slope and b the y-intercept.
I calculate the 1st line (angled down to the right) to have a slope (m) of -2 [y drops 2 for every increase of 1 for x). The y intercept is 2 (b). This equation would be y = mx+b, or y = -2x + 2.
The second line has a positive slope of 2/3 and a y intercept of -1, y = (2/3)x-1
Set these two equations equal to each other and solve for x.
-2x+2=(2/3)x-1
x = 1.125
Use that value of x to solve for y: y = -0.25
The point of intersection is therefore (1.125, -0.25)
| 7x-2 | +3 = -1 solve for x
Answer:
x = -2/7 or
x = 6/7
Step-by-step explanation:
|7x-2| + 3 = -1 subtract 3 from both sides
|7x-2| = -4 now there are two probabilities
7x-2 = -4 or
7x-2 = 4 if first probability the value of x would be:
7x-2 = -4 add 2 to both sides
7x = -2 divide both sides by 7
x = -2/7 for the second probability the value of x would be:
7x-2 = 4 add 2 to both sides
7x = 6 divide both sides by 7
x = 6/7

Answer:
Step-by-step explanation:
Domain means what is the lowest value of x on the graph and what is the highest. Our graph begins at an x value of -5 (but -5 is not included because the dot is not filled in) and goes all the way up to 2 (but 2 is not included either since the dot is not filled in. Therefore, the domain is
D = {x | x ∈ R, -5 < x < 2}
which means that the domain is in the set of real numbers that begin at -5 and end at 2, neither included.

6. Andrew is planning on taking a vacation to Santorini, Greece which will cost $5,000. He makes $2900 ser
month. His fixed expenses are $1200 each month. He spends $200 on food and 5% of his monthly salary on
entertainment. How many months will it take to save enough for Andrew to go to Santorini, Greece
Answer: 3 months
Step-by-step explanation:
Answer:
3 1/2 months (Someone please check my math)
Step-by-step explanation:
We can set up this problem by making an equation.
(2900-1200-200-5%)(x)=5000
(1500-5%)(x)=5000
(1425)(x)=5000
5000 divided by 1425 equals 3.50...
My answer would be 3 1/2 months but I could be wrong.

Answer:
$y=(7/2)x+20$
Step-by-step explanation:
SInce the gradient of the first line is $-2/7$ then the gradien of the perpendicular line is $7/2$.
Therefore by the point slope formula the line that we are looking for is
$y-6=(7/2)(x+4)$
$y=(7/2)x + 20$

if you make $391 for 17 hours how much would you make in 13 hours
Answer:
We would make $299 in 13 hours.
Step-by-step explanation:
Hi there!
We're given:
⇒ We make $391 in 17 hours
To find how much we make in 13 hours, we must first find how much we make in 1 hour. Divide $391 by 17 hours:
391 ÷ 17 = 23
Therefore, we make $23 in 1 hour.
Multiply $23 by 13 hours to find how much we would make in 13 hours:
23 × 13 = 299
Therefore, we would make $299 in 13 hours.
I hope this helps!
