Solve by substitution:

7x - y = 3
Group of answer choices
(1 , 4)
(-1 , -4)
(-1 , 4)
(1 , -4)
Answer:
(1, 4)
Step-by-step explanation:
subsitute y=x+3 into the 2nd equation, which you will get 7x-(x+3)=3
get rid of the (), which you will get 7x-x-3=3
combine like terms and get 6x-3=3
move 3 to the other side and divide both sides by 6 and get x=1
use the first equation y=x+3 and subsitude 1 for x and get y=1+3
y=4

John is going camping, and he needs to buy a tent. The outdoor store has one that cost $90, but it's on sale for 25% off. What is the sale price?
A.$22.50
B.$65.00
C.$67.50
D.$112.50
Answer:
A
Step-by-step explanation:
Okay so, im not the best at explaining, but so we have a percentage. its 25%. you want to take the 25% and put it over 100 because a percentage is a number or ratio expressed as a fraction of 100. so it will be written as 25%/100
divide 25 by 100 and you get 0.25, correct? so that's one step further towards the answer.
then we write x/90 because we don't know (well we do) what we're gonna put. but, we're gonna multiply 0.25 by 90 and we get 22.5, which is equivalent to 22.50.
What is the equation of the line that is perpendicular to the line through (1,-4) and (-2,2) and passes through the x-intercept of that line?
Answer:
y=-[tex]\frac{1}{2}[/tex]x+[tex]\frac{3}{2}[/tex]
Step-by-step explanation:
First, calculate the slope of the line that is perpendicular to the equation of line we are asked to find
m=(y2-y1)/(x2-x1)
=(2-(-4))/(-2-1)
=6/-3
=-2
in this equation the slope is 2, and to find the first equation, use y=mx+b
use the point (1, -4) to find b
-4=(2)(1)+b
-4=2+b
b=-6
the first equation of the line is y=2x-6
to find the x intercept of that line substitute 0 for y
0=2x-6
2x=6
x=3
the slope of a line perpendicular to this would be the opposite reciprocal of the slope which would be equal to -1/2
for the second equation of the line to pass thorugh the x-intercept of the first line, it must pass through (3, 0), so substitute and solve for b
y=mx+b
0=(-1/2)(3)+b
b=3/2
thus the equation of the line that is perpendicular to the line through (1,-4) and (-2, 2) and passes through the x intercept of that line is y=-[tex]\frac{1}{2}[/tex]x+3/2
The equation of the line that is perpendicular to the line through (1,-4) and (-2,2) is [tex]y= \frac{1}{2}x+3[/tex]
The equation of the line perpendicular to the line passing through the points (x₁, y₁) and (x₂, y₂) is given as:
[tex]y-y_1=\frac{-1}{m} (x-x_1)[/tex]
The slope m is calculated using the formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{2-(-4)}{-2-1} \\\\m=\frac{6}{-3} \\\\m=-2[/tex]
For the line passing through the points (1,-4) and (-2,2), substitute m = -2, x₁ = 1, and y₁ = -4 into the equation [tex]y-y_1=\frac{-1}{m} (x-x_1)[/tex]
[tex]y-1=\frac{-1}{-2} (x-(-4))\\\\y-1=\frac{1}{2}(x+4)\\\\y=\frac{1}{2}x+2+1\\\\y= \frac{1}{2}x+3[/tex]

C. [tex]-2\frac{3}{8}[/tex] < -8/6 < -0.85 < 0.8 < 4/3 < 140% in ascending order.
What is ascending and descending order ?In ascending order we write numbers from smaller to greater and in descending order we write numbers from greater to smaller.
According to the given question we have list of fractions decimals and percentages and we have to write them in ascending order.
given [tex]-2\frac{2}{8}[/tex], - 0.85, 4/3, 140%, -8/6, 0.8.
Now let convert all these into one form we choose to convert them in percentage.
[tex]-2\frac{3}{8}[/tex] is -19/8 = -2.375 = -237.5 %.
-0.85 = - 85%.
4/3 = 133%.
140% = 140%
-8/6 = -133%
0.8 = 80 %.
∴ [tex]-2\frac{3}{8}[/tex] < -8/6 < -0.85 < 0.8 < 4/3 < 140%.

It might be 2 not 100 percent sure
Answer:
isosceles (based on sides) and right triangle (based on angles)
Step-by-step explanation:
This is an isosceles triangle because two of the sides are the same distance (it is in cm.). This is also a right triangle because at point B the two lines are perpendicular (using their slopes).

Step-by-step explanation:
From Euclidean Geometry, parallelograms satisfy the following properties:
1) [tex]\angle A = \angle C[/tex], [tex]\angle B = \angle D[/tex]
2) [tex]\angle A +\angle D = \angle D + \angle C = \angle C +\angle B = \angle A+\angle B = 180 ^{\circ}[/tex]
3) [tex]AD = BC[/tex], [tex]AB = DC[/tex]
By 3):
[tex]AD = 6[/tex]
By 3):
[tex]DC = 14[/tex]
By 2):
[tex]\angle A = 180^{\circ}-\angle D[/tex]
[tex]\angle A = 180^{\circ}-66^{\circ}[/tex]
[tex]\angle A = 114^{\circ}[/tex]
By 1):
[tex]\angle B = 66^{\circ}[/tex]
By 1):
[tex]\angle C = 114^{\circ}[/tex]
Sand falls onto a conical pile at the rate of 10 cubic feet per minute. The radius of the pile is always equal to one half it altitude. How fast is the altitude of the pile increasing when the pile is 5 feet high?
Answer:
Either one of these.
Step-by-step explanation:
volumepile=1/3 (PI r^2)h
but r=h/2, so
volume=1/12 PI h^3
dv/dt=10 ft^3/min
but dv/dt=1/12 PI 3h^2 dh/dt
solve for dh/dt
This assumes you mean by "altitude" the height. If you mean altitude as slant height, you have to adjust the fromula
_______________________________________________
given: r = h/2
V = (1/3)π r^2 h
= (1/3)π (h/2)^2 (h)
= (1/12) π h^3
dV/dt = (1/4)π h^2 dh/dt
for the given data ...
10 = (1/4)π(25)dh/dt
dh/dt = 10(4)/((25π) = 1.6/π feet/min

Answer:
The graduate will have $4,084.97 when he cashes in the CD at the end of the 36-months.
Step-by-step explanation:
This can be determined using the formula for calculating the future value (FV) formula as follows:
FV = PV * (1 + r)^n ................................. (1)
Where;
FV = Future value or the amount the graduate will have at end of 36 months = ?
PV = Present value or the total amount invested = Cash gifts from friends and relatives + Amount of 3 scholarships he received = $900 + $250 + $300 + $1,400 = $2,850
r = daily interest rate = 1% / 360 = 0.01 / 360 = 0.0000277777777777778
n = number of days = 36 months * 360 days = 12,960
Substituting the values into equation (1), we have:
FV = $2,850 * (1 + 0.0000277777777777778)^12,960
FV = $2,850 * 1.43332224806396
FV = $4,084.96840698229
Approximating to the nearest cent as required, we have:
FV = $4,084.97
Therefore, the graduate will have $4,084.97 when he cashes in the CD at the end of the 36-months.

Oh phone company offers to monthly plans plan a cost $13 plus an additional $.14 for each minute of calls Plan B cost $18 plus an additional of $.09 for each minute of calls.
For what amount of calling do the two plans cost the same?
What is the cost when the two plans cost the same?
Answer:
For 100 minutes
Step-by-step explanation:
Step one:
given data
Oh phone company
monthly plans plan a cost $13 plus an additional $.14 for each minute of calls
let the number of minutes be x, and the total be y
y= 13+0.14x--------------------1
Plan B cost $18 plus an additional of $.09 for each minute of calls
let the number of minutes be x, and the total be y
y= 18+0.09x--------------------2
Step two:
Equate 1 and 2 above
13+0.14x=18+0.09x
collect like terms
18-13= 0.14x-0.09x
5=0.05x
divide both sides by 0.05
x=5/0.05
x=100 minutes
