y = 9x + 14
y = 4x + 49
Answers
Answer:
x = 7; y = 77
Step-by-step explanation:
y = 9x + 14
y = 4x + 49
Since both equations are solved for y, set the two right sides equal and solve for x.
9x + 14 = 4x + 49
5x = 35
x = 7
Sow substitute 7 for x in the first equation and solve for y.
y = 9x + 14
y = 9(7) + 14
y = 63 + 14
y = 77
Answer: x = 7; y = 77
Answer:
x=7 y=77
Step-by-step explanation:
Subtract 4x from 9x you get 5x
subtract 14 from 49 you get 35
5x=35
9*7=63+14=77
4*7=28+49=77

Compare the graph of y = 4x and y = 4x + 1.
how are they the same how are they different
Answers
Answer:
Step-by-step explanation:
Notice that the difference is in the y-intercept. The first equation has a y-intercept of 0 since y = 4x + 0, the second has a y-intercept of 1 since
y = 4x + 1. In other words, the graph is translated up 1 unit to cross at (0,1) instead of (0,0)

Amir pits £3035 into a bank account. The account pays 4% compound interest each year. Work out how much money amir will have in the account after 6 years
Answers
Answer:

Step-by-step explanation:
Let P denotes principal amount, T denotes time period and R denotes rate of interest.
Amount = [tex]P(1+\frac{R}{100})^T[/tex]
Amir pits £3035 into a bank account. The account pays 4% compound interest each year.
Put [tex]P=\£3035,\,R=4\%,\,T=6[/tex]
Amount = [tex]3035(1+\frac{4}{100})^6=3035(\frac{104}{100})^6=\£3840.2[/tex]

Answers
Answer: 84.8°
Step-by-step explanation:
a²+b²+c²-2bc(cosA)
cosA = b² + c² - a² / 2bc
That is the formula we will be using.
Then, plug in our numbers.
cosP= 500² + 380² - 600² / 2(500)(380)
cosP= 34400/380000
cosP≈ 0.09052631
cos⁻¹(0.09052631) ≈ 84.81
∠P = 84.8°

Answers
Answer:
100 inches
Step-by-step explanation:
Given that the mans height is 71 inches. Height of lamp is 108 inches and distance between them is 52 inches. For Figure refer to attachment . The given figure both triangles are similar by AA similarity Condition. So we know that the corresponding parts of similar triangles are proportional .Let Distance between man a d its shadow be x .
Using this concept ,
=> AM / PN = QA / QP
=> 108 / 71 = 52 + x / x
=> 1.52 x = 52 + x
=> 1.52 x - x = 52
=> 0.52 x = 52
=> x = 52/0.52
=> x = 100 in .
What is an equation of the line that passes through the point ( − 1 , − 3 ) and is perpendicular to the line x − 2 y = 14? pls answer will mark you as brainiest
Answers
Answer:
y = -2x - 5
Step-by-step explanation:
First rewrite the second equation into y = mx + b format:
x - 2y = 14
2y = x - 14
y = x/2 - 14/2 (Divide both sides by 2)
y = 1/2x - 7
A line perpendicular to another has the negative reciprocal slope
So the slope of our first equation is -2. (Flip 1/2 = 2, then take the opposite)
Plug in the points (-1, -3) for the x and y coordinates.
x (x coordinate) = -1
y (y coordinate) = -3
slope (m) = -2
-3 = -1(-2) + b
-3 = 2 + b
-3 - 2 = b
b = -5
The equation of the line is y = -2x - 5. Hope this helps! :)
Answer:
y = -2x - 5 or 2x + y = -5
Step-by-step explanation:
Let's find the slope of the given line.
-2y = -x + 14
y = 1/2(x) -7
m = 1/2
The slope of a line perpendicular is the negative reciprocal of 1/2, which is -2
Now use the point-slope form of a line
y + 3 = -2(x + 1)
y + 3 = -2x - 2
y = -2x - 5 or 2x + y = -5
An item is regularly priced at $24. Christine bought it on sale for20% off the regular price.How much did he pay for it
Answers
Answer:
$19.2
Hope this helps!! :)
Answer:
$19.20
Step-by-step explanation:
First find how much 20% of 24 is.
What is 20% of 24?
Y is 20% of 24
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 20% * 24
Converting percent to decimal:
p = 20%/100 = 0.2
Y = 0.2 * 24
Y = 4.8
Then subtract that from $24
Which gives you $19.2

Is 7 a solution for the equation 3(x + 4)= 2x - (-2x)?
Answers
Step-by-step explanation:
3x+12=2x+2x
3x+12=4x
3x-4x=-12
-x=-12
x=12
Answer:
no, the answer is x = 12
Step-by-step explanation:
3(x + 4)= 2x - (-2x)
3(x + 4)= 2x + 2x
3x + 12 - 12 = 4x - 12
3x - 4x = 4x - 12 - 4x
