Step-by-step explanation:
Since Castel sold 6 apple pies and 4 lemon meringue pies for $80, we have 6x + 4y = $80.
Also Gabriella sold 6 apple pies and 5 lemon meringue pies for $94, we have 6x + 5y = $94.
6x + 5y = $94
- (6x + 4y = $80)
=> y = $14.
Therefore 6x + 5($14) = $94, 6x = $24, x = $4.
Hence each apple pie costs $4 and each lemon meringue pie costs $14.
The slope is -1 and the y-intercept is -5. Write a linear equation in slope-intercept form.
Someone pls help me!
[tex]y = mx + b[/tex]
where m = slope and b = y-intercept.
We have both given slope and y-intercept. We can simply substitute the given slope and y-intercept in slope-intercept form.
SubstitutionSubstitute m = -1 and b = - 5 in the equation.
[tex]y = - 1x - 5 \\ y = - x - 5[/tex]
We don't usually write 1x or -1x instead we write -x or x.

find the slope of the line which is perpendicular to the line 7 x + 11 Y - 2=0
Answer:
[tex]\huge\boxed{slope=-\dfrac{7}{11}}[/tex]
Step-by-step explanation:
METHOD 1The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
[tex]m[/tex] - slope
[tex]b[/tex] - y-intercept
We have the equation in the general form [tex](Ax+By+C=0)[/tex].
Convert to the slope-intercept form:
[tex]7x+11y-2=0[/tex] subtract 7x from both sides
[tex]11y-2=-7x[/tex] add 2 to both sides
[tex]11y=-7x+2[/tex] divide both sides by 11
[tex]y=-\dfrac{7}{11}x+\dfrac{2}{11}[/tex]
METHOD 2The general form of an equation of a line:
[tex]Ax+By+C=0[/tex]
The slope:
[tex]m=\dfrac{-A}{B}[/tex]
We have
[tex]7x+11y-2=0\\\\A=7;\ B=11;\ C=-2[/tex]
Substitute:
[tex]m=\dfrac{-7}{11}=-\dfrac{7}{11}[/tex]
4. Write the equation of line that is perpendicular to y= -1/3x + 7 and has a y intercept of -1.
1
Answer:
y = 3x - 1Step-by-step explanation:
Two lines are perpendicular if the product of theirs slopes is equal -1:
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇒ m₁×m₂ = -1
y = -1/3x + 7 ⇒ m₁=-1/3
-1/3×m₂ = -1 ⇒ m₂ = 3
The y-intercept is b=-1 so the equation in slope-intercept form:
y = 3x - 1

You can rent a car via two options. Option A charges $20 per day plus $0.10 per mile. Option B charges $0 per day, but $0.50 per mile. How many miles must you drive in one day for option A to be cheaper?
Answer:
50 miles
Step-by-step explanation:
Step one
given data
let the total charge be y and the number of miles be x
Option A charges $20 per day
plus $0.10 per mile.
y= 20+0.1x---------------1
Option B charges $0 per day,
but $0.50 per mile
y= 0.5x---------------2
equate 1 and 2 we have
20+0.1x=0.5x
20=0.5x-0.1x
20=0.4x
divide both sides by 0.4
x= 20/0.4
x=50 miles

Answer:
angle 1 = 100 degrees
angle 2 = 53 degrees
Step-by-step explanation:
diagonals of a rhombus bisect angles so angles 2 and 3 are both 53
angle 1 can be found by adding 37 and 53 and deducting that sum from 180
Combine like terms to create an equivalent expression. 4\left(1.75y-3.5\right)+1.25y4(1.75y−3.5)+1.25y
Answer:
8.25y + 14
Step-by-step explanation:
Given the expression
[tex]4\left(1.75y-3.5\right)+1.25y[/tex]
We are to simplify it as shown
Open the parenthesis
4(1.75y) - 4(3.5) + 1.25y
7y - 14 + 1.25y
Collect the like terms
7y + 1.25y - 14
8.25y + 14
Hence the required expression is 8.25y + 14

8.25y−14

5) For every 14 students who run track, there are 6 students who play baseball. There are 128 more students who run track than play baseball.
How many students run track?
How many play baseball?
Answer:
So we divide 128 into 14 which is 9.14285714286 but that eo be impossible so next we round to the nearest number which is now 9 now we multiply 9 by 14 and that gives us 126
I believe this is the answer
The answer is 126 and second ........ 132
