Write the equation of a line that is parallel to y= -5x + 4 and passes through the point (3,-1)
Answer:
y = -5x + 14
Step-by-step explanation:
Parallel lines have the same slope, and their equations are identical except for the value of the constant (which in turn is the y-intercept).
Both lines have the slope m = -5. Start with y = mx + b, or y = -5x + b. Then substitute 3 for x and -1 for y:
-1 = -5(3) + b, or:
14 = b (the y-intercept is 14)
Then the desired equation is y = -5x + 14.

Step-by-step explanation:
seperate the prism into two. for the long rectanglular prism the formula is (6x2)x2 which is equal to 24. for the wider rectangular prism it's (4x4)x2=32. Add 32 and 24 together which makes the answer 56
What is 8x-2y=6 is slop-intercept form
Answer:
y= 4x -3
Step-by-step explanation:
1) add -8x at both members
8x - 2y - 8x = 6 - 8x
-2y = -8x + 6
2) divide both members by -2
y = 4x -3

Step-by-step explanation:
A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs
Characteristics of a trapezoid
It has 4 vertices and edges
If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram
Area of a trapezoid = x (sum of the lengths of the parallel sides) x height
Perimeter = sum of lengths of sides of a trapezoid

HOW TO DO THIS QUESTION
9514 1404 393
Answer:
583.4 cm³
Step-by-step explanation:
We have the base dimensions, so enough information to find its area:
A = s²
A = (10 cm)² = 100 cm²
__
The height of the triangle is found by solving triangle AMV for the distance MV. That is found from the trig relation ...
Tan = Opposite/Adjacent
tan(68°) = MV/AM
The length of AM is half the diagonal of the square base, so is (10√2)/2 = 5√2. The length of MV is ...
MV = AM·tan(68°) = 5√2·tan(68°) ≈ 17.50
So, the volume of the pyramid is ...
V = (1/3)Bh
V = (1/3)(100 cm²)(17.50 cm) ≈ 583.4 cm³ . . . . volume of the pyramid

Step-by-step explanation:
The segments in each figure are tangent to the circle at the points shown.
Find each length.
Answer:
y = 12
Step-by-step explanation:
The segments are equal in length, SR = TR, so set up an equation:
[tex]\frac{y^2}{12}=y[/tex]
Multiply by 12.
[tex]y^2=12y\\y^2-12y=0[/tex]
Factor out the y on the left side.
[tex]y(y-12)=0[/tex]
There are two solutions: y = 0 and y = 12. The y = 0 solution makes no sence (segment SR can't have a length of 0). The other solution, y = 12, works just fine.
Solve the equation for x.

Answer:
The second deal is better. It is $2.042 per gallon
Step-by-step explanation:
$11/5 and 51.05/25 are the deals.
Let's multiply the first deal by 5/5.
That is $55 per 25 gallons and the other deal is $51.05 per 25 gallons.
So the second deal is better.
Now lets divide 51.05 by 25 to find out how much dollars per gallon
51.05 / 25 = 2.042, so it is $2.042 per gallon.
At the bottom is a completed addition problem, with all the digits replaced by letters. Every letter represents a single digit and different letters represent different digits. Which digit might the letter T represent. MH + MH MH = TM
Answer:
T = 5 (H = 7, M = 1); T = 7 (H = 4, M = 2); T = 9 (H = 1, M = 3)
Step-by-step explanation:
We know MH+MH+MH=TM
MH is a two digit number, and TM is also a two digit number.
MH+MH+MH=3*(MH)<100
3M<=9, meaning that M could be 1, 2, or 3.
If M=1, MH+MH+MH=3(10+H)=30+3H=TM=10*T+1
30+3H=10T+1, so 3H must include 1 in one's digit.
The only possibility is that 3H = 21, then H = 7
MH+MH+MH=17+17+17=TM=51, T = 5
If M=2, MH+MH+MH=3(20+H)=60+3H=TM=10T+2
60+3H=10T+2, so 3H must include 2 in one's digit.
The only possibility is 3H = 12, then H = 4
MH+MH+MH=24+24+24=72, T = 7
If M=3, MH+MH+MH=3(30+H)=90+3H=TM=10T+3
90+3H=10T+3, so 3H must include 3 in one's digit.
The only possibility is 3H = 3, then H =1
MH+MH+MH=31+31+31=93, T=9
We will see that if we define M = 2, and H = 4, the value that T takes is T = 7
Which digit the letter T represent?We know that:
MH + MH + MH = TM
We can write this as:
M*10 + H + M*10 + H + M*10 + H = T*10 + M
30*M + 3*H = T*10 + M
30*M - M + 3*H = T*10
(29*M + 3*H)/10 = T
Now we need to find two values for M and H such that T is a digit.
For example, if M = 2 we have:
(29*2 + 3*H)/10 = T
(58 + 3*H)/10 = T
Now we can take H = 4, then we get:
(58 + 3*4)/10 = T
(58 + 12)/10 = T = 7
In this case, we found that a possible value of T is T = 7.
