Write the equation of a line that is perpendicular to y=-2/7x + 9 and that passes through the point (-4,6) [FP]
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
$y-6=(7/2)(x+4)$
$y=(7/2)x + 20$
Find the value of AB.
Step-by-step explanation:
Since all side lengths of smaller squares are equal, we have
[tex]3x+4=4x-1[/tex]
[tex]x=5[/tex]
Since length of AB is twice of the side length of smaller squares,
[tex]\bar{AB}=2(3x+4)=2(3\cdot5+4)=38[/tex]
Answer:
AB=38

Solve the equation x^2-12x=0
Answer:
x=0
x=12
Step-by-step explanation:
Set up the equation
x^2-12x=0
Factor out x
x(x-12)=0
Set each factor equal to 0.
x=0
(x-12)=0
x=12
if f(x)=3x-7 evaluate f(-2w+1/2)=
Step-by-step explanation:
f(x) = 3x - 7
f (-2w + .5) = 3(-2w + .5) - 7
= -6w + 1.5 -7
= -6w - 5.5
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.

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)

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

PLEASE MARK ME BRAINLIEST.Need help with #12
Please help
Step-by-step explanation:
If the figure is triangle then,
Let PR be x
So,
PQ+QR+PR= 180 (Sum of all the angles of the triangle)
Therefore,
6x+25+16-3x+x=180
4x+36=180
4x= 180/36
x= 144/4
X= 36
NOW,
PQ= 6x+25
= 6(36)+25
= 216+25 = 241= PQ.
QR = 16-3x
= 16-3(36)
= 16-108
= -92
PR = 36

PR = 36

Answer:
The square root of 2 is between 1 and 2, so radical 2 is about 1.4.
Step-by-step explanation:
You can plot a 1 on the very left and a 2 on the very right of the number line.
Since there is no formal square root of 2, you have to estimate.
It has to be less than 2 because if you multiply 2 * 2 you get 4 and that's too big; we want to get 2.
It also has to be greater than 1 because 1 * 1 = 1 and that's too low.
I would estimate it to be right before the middle line.

| 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
