Answer:
a. y = -x
b. Area = xy
c. x = -y
Step-by-step explanation:
a. The perimeter of the garden is the distance all the way around, in this would be x+y+x+y, or 2x + 2y. To solve for y, we’re trying to isolate it on one side. We need to subtract 2x to get 2y = -2x. Divide by 2 to get y = -x.
b. Area is length times width, so x • y, or xy.
c. To express in terms of x, we can take the equation y = -x and multiply it by -1 to get x = -y

Answer:
15$ a day would be the estimate for 1 day
Step-by-step explanation:
Part a)
The diagonal line goes through (0,15) and (2,20)
Find the slope based on those points
[tex](x_1,y_1) = (0,15) \text{ and } (x_2,y_2) = (2,20)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{20 - 15}{2 - 0}\\\\m = \frac{5}{2}\\\\m = 2.5\\\\[/tex]
The y intercept is b = 15 because this is where the line crosses the y axis.
We go from y = mx+b to y = 2.5x+15.
Now plug in x = 1 to find the cost of renting for one day.
y = 2.5x+15
y = 2.5*1+15
y = 17.5
Another way to get the answer is to start at 1 on the x axis number line. Draw a vertical line upward until you reach the curve. From there, draw a horizontal line toward the y axis (refer to the diagram below). You should land somewhere between 15 and 20. The midpoint of which is 17.50
Answer: $17.50=====================================================
Part b)
We can do the reverse idea of the previous part.
Start at y = 25 on the y axis. Draw a horizontal line toward the curve. After reaching the curve, draw a vertical line down until you hit the x axis. You should arrive at x = 4.
Or you can use the algebraic approach since we know the cost equation
y = 2.5x+15
25 = 2.5x+15 ... plug in y = 25
25-15 = 2.5x
10 = 2.5x
2.5x = 10
x = 10/(2.5)
x = 4

Answer:
AC = 2.96
Step-by-step explanation:
Use the trigonometric ratio cosine:
cosine = adjacent ÷ hypotenuse
cos(65°) = AC ÷ 7
[tex]cos(65) = \frac{AC}{7}[/tex]
Multiply both sides by 7:
7(cos(65)) = AC
(Note: Set your calculator to degrees!)
And plug 7(cos(65)) into your calculator to get:
AC ≈ 2.96

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels 18 miles per hour slower than the westbound train. If the two trains are 570 miles apart after 3 hours, what is the rate of the eastbound train?
Formula: Distance = rate * time
570 = (R+(R-18))*3
570 = (2R - 18)*3
190 = 2R-16
208 = 2R
R = 104
Eastbound Train: 86mph
Westbound Train: 104mph
how can i solve it formula y= mx + b
Answer:
y = 4/3x - 4
Step-by-step explanation:
you are given b
so y = mx -4
you can look at the graph and see the slope from there. like the y-intercept and the x-intercept
(0,-4) and (3,0)
slope formula is y2-y1/x2-x1
and so you do -4-0/0-3
-4/-3.
so your slope formula would be
y = 4/3x - 4

i really need some help on this math problem?can you help me
Answer:
7 units
Step-by-step explanation:
Forming an equation:
There is a one-time signup fee. Let that be represented by "a".
Then, there's also a weekly fee. Let that be represented by "b", i.e., the fee for one week is "b" units.
==> If she goes to the gym for x weeks, then her total weekly fee will be "b" times "x" units.
If we represent her total cost after membership by "y", our equation becomes:
[tex] \boxed{ \sf{y = a + bx}}[/tex]
We're provided with three values of x and y.
When x = 6, y = 133When x = 12, y = 175When x = 24, y = 259The solution to the equation:
Substitute the respective values of x and y into the equation.
#1
133 = a + 6b
==> a = 133 - 6b
#2
175 = a + 12b
Since we only need the values of two variables we'll use only two equations.
Substituting from #1 for a:
175 = (133 - 6b) + 12b
==> 175 = 133 + 6b
==> 175 - 133 = 6b
==> 42 = 6b
==> b = 7
And b is the amount she pays each week.
So, the answer is 7 units.

A realtor uses a lock box to store the keys to a house that is for sale. The access code for the lock box consists of six
digits. The first digit cannot be 4 and the last digit must be even. How many different codes are available? (Note that 0
is considered an even number.)
Answer:
450,000
Step-by-step explanation:
The first digit has 9 choices
Digits 2 through 5 each have 10 choices
Digit 6 has 5 choices.
9 * 10 * 10 * 10 * 10 * 5 = 450,000

what is the slope of y−4=−7(x−6)
Answer:
slope = - 7
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
y - 4 = - 7(x - 6) ← is in point- slope form
with slope m = - 7
Answer:
M= -7
Step-by-step explanation:
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
y - 4 = - 7(x - 6) ← is in point- slope form
with slope m = - 7

In right triangle ABC, C is the right angle. What does sinB equal? options: sinB, cosB, cosA, not enough information
Answer:
Answer: cos(A)
Step-by-step explanation:
» From trigonometry,
[tex]{ \tt{ \sin( \theta) = \frac{opposite}{hypotenuse} }} \\ [/tex]
[tex]{ \tt{ \red{ \sin(B) = \frac{AC}{AB} }}} \\ [/tex]
» For cosine:
[tex]{ \tt{ \cos( \theta) = \frac{adjacent}{hypotenuse} }} \\ \\ { \red{ \tt{ \cos(A) = \frac{AC}{AB} }}}[/tex]
» Therefore, sinB = cosA
Answer:
Not enough information
explanation:
Taking sin here:
∠A + ∠B + ∠C = 180°
∠A + ∠B + 90 = 180°
∠A + ∠B = 90°
sin(A) + sin(B) = sin(90)
sin(B) = 1 - sin(A)
Taking cos here:
∠A + ∠B + ∠C = 180°
∠A + ∠B + 90 = 180°
∠A + ∠B = 90°
cos(A) + cos(B) = cos(90)
cos(A) + cos(B) = 0
cos(B) = -cos(A)

Answer:
a = 6.5 mperimeter = 52 mStep-by-step explanation:
The shape is a trapezoid on top of a parallelogram. The areas of each of the figures can be found separately, then added together.
Trapezoid areaThe area formula is ...
A = 1/2(b1 +b2)h . . . . where b1, b2 are the base lengths and h is the height
A = 1/2(12 +a)(7) = 3.5(12 +a) = 42 +3.5a
__
Parallelogram areaThe area formula is ...
A = bh
A = (12)(9) = 108
__
The area of the figure is then ...
total area = trapezoid area + parallelogram area
172.75 = 42 +3.5a + 108
22.75 = 3.5a . . . . . . . . . . . . subtract 150
6.5 = a . . . . . . . . . . divide by 3.5
The length 'a' is 6.5 meters.
__
PerimeterThe perimeter is the sum of the side lengths. Opposite sides of the parallelogram are the same length. Clockwise from the bottom left, the sum of side lengths is ...
P = 9.2 +7.8 +6.5 +7.3 +9.2 +12 . . . meters
P = 52 . . . meters
The perimeter is 52 meters.
