Answer: ( -2, 7 )
Step-by-step explanation:
Solve 4x + y = -1 for y:
Add -4 to both sides:
4x + y + -4 = -1 + -4
y = -4x - 1
Now plug -4x -1 in the other equation with y:
-5x - 2 ( -4x -1 ) = -4
3x + 2 = -4
Add -2 to both sides:
3x + 2 - 2 = -4 + -2
3x = -6
Now divide both by 3:
3x/3 = -6/3
x = -2
Now plug in -2 in the first equation with x:
y = - 4 ( -2 ) - 1
y = 7
Find the area of a right triangle with a height of 8 1/2 feet and a base of 15 feet
Answer:
63.75
Step-by-step explanation:
The equation for finding the area of a triangle is 1/2b x h
b = base
h = height
b = 15
h = 8.5
15(1/2) x 8.5
7.5 x 8.5 = 63.75
Answer:
A = 63.75 ft^2, or 63 3/4 ft^2
Step-by-step explanation:
The formula for the area of a triangle of base b and height h is
A = (1/2)(b)(h).
With h = 8.5 ft and b = 15 ft, the area of the triangle in question is
A = (1/2)(8.5)(15)ft^2, or
A = 63.75 ft^2, or 63 3/4 ft^2

Answer:
Step-by-step explanation:
Point of intersections of the graph with x-axis are not clear.
Let these points are x = -a, -b and c
Therefore, function representing the graph will be,
f(x) = p(x + a)(x + b)(x - c)
Since, this graph crosses y-axis at (0, -6),
f(0) = p(0 + a)(0 + b)(0 - c) = -6
-pabc = -6
p = [tex]\frac{6}{abc}[/tex]
Therefore, equation of the given function will be,
f(x) = [tex]\frac{6}{abc}(x+a)(x+b)(x-c)[/tex]
John bought a crate of floor tiles $100. The crate had 5 boxes of floor tiles. Each box contained 40 floor tiles. Write an equation to determine the cost per tile, t.
Answer:
5x+40=100
Step-by-step explanation:
The equation to determine the cost per tile, t will be [tex]\rm 200 \times t =100[/tex] and the cost per tile, t = 1/2$.
The total cost of a crate of floor tiles was $100 which had 5 boxes of floor tiles and each box contained 40-floor tiles. we have to determine the equation for the cost per tile, t.
What is the cost per tile?Here, Cost per tile = $t
Per Box Contain 40 tiles.
So, Price for 1 box = [tex]\rm 40\times t[/tex]
and Total price of crate = [tex]\rm 40 \times t \times5[/tex]
Therefore, [tex]\rm 40 \times t \times5=100[/tex]
[tex]\rm 200 \times t =100[/tex]
[tex]\rm t = \frac{1}{2}[/tex]
Hence, the cost per tile, t = 1/2.
The equation to determine the cost per tile, t will be [tex]\rm 200 \times t =100[/tex] and the cost per tile, t = 1/2$.

What is the area of this figure?
Answer:
[tex]\Huge\boxed {A =859ft^{2} }[/tex]
Step-by-step explanation:
Hello There!
To solve for the area of this figure we need to split the figure into 3 different parts:
A rectangle with a length of 9 ft and a width of 7 ft
a rectangle with a width of 9ft + 7ft and a length of 25 ft
a rectangle with a width of 18 ft and a length of 22 ft
To find the area of a rectangle we use the formula
[tex]A=w*l[/tex] where w = width and l = length
for the first one we plug in the values
A = 9 * 7
9 * 7 = 63 so the area of the smallest rectangle is 63ft²
Now lets find the area of the larger rectangle
The dimensions are l = 25 ft and w = 9 + 7 (16 ft)
Now we can plug in the values into the area formula
A = 16 * 25
16*25=400 so the area of the larger rectangle is 400 ft²
Now lets find the area of the last rectangle
The dimensions are l = 22 ft and w = 18 ft
now lets plug in the values to the formula
A = 22 * 18 =396
so the area of the last rectangle is 396 ft²
Finally we want to add all of the areas together
396 + 400 + 63 = 859
So the area of the figure is 859 ft²

department store sells a pair of shoes with a 33% discount coupon. If the store orignially sold the shoes for $55.25, what is the sale price?
Answer:
The sale price is $37.02.
Step-by-step explanation:
With the information provided, you can find the sale price by calculating 33% of the price which is the discount and subtracting that amount from the price:
$55.25*33%=$18.23
$55.25-$18.23=$37.02
According to this, the answer is that the sale price is $37.02.

An equilateral triangle with side length 9 cm is shown in the diagram, work out the area of the triangle.
Give your answer rounded to 1 DP.
Question:-
Find the area of an equilateral triangle with side length = 9cm correct upto one decimal place.
_______________________________________________
Solution:-
In an equilateral triangle all sides are equal.
Let s = side length = 9 cm
Then, area of equilateral triangle is given as:
A = (√3/4)s²
Putting the value of s here,
A = (√3/4) * (9 cm)²
=> A = (√3/4) * 81 cm²
=> A = √3 * 20.25 cm²
We know that, √3 = 1.732
=> A = 1.732 * 20.25 cm²
=> A = 35.073 cm²
Rounding to one decimal place,
=> A = 35.1 cm²
_______________________________________________
The answer is 35.1 cm².

Given: Angle ^HMA is bisected by MT.
HT = MT
Find the measure of angle ^MAT.
Answer:
angle MAT=48
Step-by-step explanation:
angle H = 44
angle M = 88
angle A = 48
triangle HTM is an isosceles triangle which means its other two angles are congruent and to find those two measurements we do (180-92)/2=44MT bisects, meaning split equally in half, so we multiply 44 by 2 and now we have angle measures of H&M180-(H+M)= AA car traveled 187 miles in 4 hours and 16 minutes.

To find:
The inverse function [tex]f^{-1}(x)[/tex].
Solution:
We have,
[tex]f(x)=\dfrac{8\sqrt[3]{x}-8}{9}[/tex]
Step 1: Putting f(x)=y, we get
[tex]y=\dfrac{8\sqrt[3]{x}-8}{9}[/tex]
Step 2: Interchange x and y.
[tex]x=\dfrac{8\sqrt[3]{y}-8}{9}[/tex]
Step 3: Isolate variable y.
[tex]9x=8\sqrt[3]{y}-8[/tex]
[tex]9x+8=8\sqrt[3]{y}[/tex]
[tex]\dfrac{9x+8}{8}=\sqrt[3]{y}[/tex]
Taking cube on both sides, we get
[tex]\left(\dfrac{9x+8}{8}\right)^3=y[/tex]
[tex]y=\left(\dfrac{9x+8}{8}\right)^3[/tex]
Step 4: Putting [tex]y=f^{-1}(x)[/tex], we get
[tex]f^{-1}(x)=\left(\dfrac{9x+8}{8}\right)^3[/tex]
Therefore, the correct option is C.

Answer:
126°
Step-by-step explanation:
To find the exterior angle, we need to know one of the acute angles. Those are found using the fact that they are complementary.
(5x -6) +(3x) = 90
8x = 96 . . . . . . . . . . . add 6, collect terms
x = 12 . . . . . . . . . . . . . divide by 8
3x° = 3·12° = 36° . . . . . . find the "remote" acute angle
exterior angle = 90° +36°
exterior angle = 126°
__
The exterior angle is the supplement of the one marked (5x-6)°. It is also the sum of the two remote interior angles, 90° and 3x°. Being lazy, we figure that 90 +3·12 is easier to compute than 180 - (5·12 -6). Either way, the exterior angle is 126°.

Answer:

Step-by-step explanation:
180-123=57
180-(57+80)=43
Answer:
x=43
Step-by-step explanation:
the other two angles measure 80 (vertical angles are equal) and 57, (straight lines make 180 degree angles)
so x = 43 because 180-(80+57)=43 (180 degrees in a triangle)
Beach towels are on sale for $1.50 off of the regular price. Ms. Ortiz buys 4 beach towels on sale for a total of $33.96. Use equations to determine the regular price of a beach towel.
Answer: $9.99
Step-by-step explanation:
From the question, we are informed that beach towels are on sale for $1.50 off of the regular price and that Ms. Ortiz buys 4 beach towels on sale for a total of $33.96.
The amount for each beach towel bought will be:
= $33.96/4
= $8.49
Since there's $1.50 off the normal price, that means the normal price for each will have been:
= $8.49 + $1.50
= $9.99

Answer:
65.6%
Step-by-step explanation:
The question is essentially asking the ratio of the volumes.
Va = πr²h = π(15²)(20)
Vb = πr²h = π(19²)(19)
The ratio of volumes is ...
Va/Vb = π(15²)(20)/(π(19³)) = (15²)(20)/19³ ≈ 0.65607
Container B will be about 65.6% full when container A is empty.
