49, here's why...
a negative multiplied by a negative equals a positive, and if you're working with parentheses, and you don't see a sign, at all, then it means you have to multiply.
hope I helped :)
A plane took 3 h 33 min to finish a journey. If the distance of the journey was 2840 miles, at what average speed did the plane travel?
Answer:
800mph
Step-by-step explanation:
Step one
Given data
time taken= 3 h 33 min
= 3.55 hours
distance = 2840 miles
Step two:
from speed= distance/time
substitute
speed= 2840/3.55
speed= 800mph
Hence the speed is 800mph
Find the slope of the line 3,0 and 0,-3
Answer:
1
Step-by-step explanation:
The slope of the line is 1. To find slope use the formula [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex], this calculates the change in y over the change in x. So plug in the known values [tex]\frac{0+3}{3-0}[/tex], this equals 3/3 or 1. This means every time y increases by 1, x will also increase by 1.

Answer:
f(x)=0.5x+3.5, x<1
f(x)=-2x+6, x>1
Step-by-step explanation:
Find the Point of Interest, which is at x=1 because the direction changes. Find the slope (rise/run) of the line on the left which is 1/2 or 0.5. Find the y-intercept by plugging in the given point: (-3, 2). 0.5(-3)+c=2 so the y-intercept is 3.5. Do the same for the line on the right.

Answer:
18. 56
19. 132
20. 55
21. 120
22. 129.5
23. 61.3
Step-by-step explanation:
First look at the lines arrangment
angle 1+angle 5=180 and according to corresponing angles theorem angle 5 and angle 2 are equivalent. Angle 1+4=180
180-124=56
Angle 2+3=180
180-48=132
According to corresponding angles
angle 4=angle 7 and angle 7=angle 2 meaning angle 4=5
so angle 5=2
Like everything opposite to each other is conr=gruent
angle 8=angle 1 and angle 1=angle 6
means both angle 6 and 8 are congruent.
LOOK angle 7+3=180 means angle 2+6=180
so if ANGLE 7=50.5
6=3
180-50.5=129.5
23. angle 6 and 3 are congruent and as you know angle 7+3=180 and angle 2+6=180
angle 3+angle 6=180
180-118.7=61.3
18. Measure of angle 1=124 then angle 4=56
19.Angle 2= 48 then angle 3=132
20.Angle 4=55 then angle 2=55
21. angle 6=120 then angle 8=120
22.angle 7=50.5 then angle 6=129.5
23.angle 3=118.7 then angle 2=61.3
Hope this helps!!

The radius of a circle is 1 foot. What is the area of a sector bounded by a 90 degree arc?
Answer:
The answer is 11/14 ft^2 or pi/4 ft^2
Step-by-step explanation:
The area of the sector bounded by that angle measure will be the area of the circle divided by 4
Area of the circle is;
pi * r^2
so the area here is;
22/7 * 1 * 1 = 22/7
divide this by 4
= 22/28 = 11/14 ft^2
y=2x+5. It says Complete the missing value in the solution to the equation. I NEED TO SOLVE FOR X
Answer: X=y/2-5/2
Step-by-step explanation:
Answer:
x=1/2y+(−5/2) or x=y-5/2
Step-by-step explanation:
Step 1: Flip the equation.
2x+5=y
Step 2: Add -5 to both sides.
2x+5+−5=y+−5
2x=y−5
Step 3: Divide both sides by 2.
2x/2=y−5/2
x=1/2y+(−5/2) or x=y-5/2
Jenna has already cycled 8 kilometers this year,plus she plans to cycle 2 kilometers during each trip to work.Write an equation that shows the relationship between the number of trips to work t and the total distance cycled d.
Answer:
[tex]d = 8 + 2t[/tex]
Step-by-step explanation:
Given
[tex]Rate = 2km/trip[/tex]
[tex]Base\ Cycle = 8km[/tex]
[tex]d = total\ distance[/tex]
[tex]t = cycles[/tex]
Required
Determine the expression for this scenario
The expression can be derived from:
[tex]Total\ Distance = Base\ Cycle + Rate * Cycles[/tex]
Substitute d for Total Distance and t for cycles
[tex]d = Base\ Cycle + Rate * t[/tex]
Substitute values for Base Cycle and Rate
[tex]d = 8 + 2* t[/tex]
[tex]d = 8 + 2t[/tex]
what is the answer to this eqution 3.5(x+2)=-4 ? could you please help me thank you
Answer:
x=-3.14
or -3 with -.5 remainder
Step-by-step explanation:
PEMDAS
Parenthesis Exponent Multiply Divide Add Subtract
parenthesis 3.5*x=3.5x 3.5*2=7
3.5x+7=-4
subtract 7 from both sides
3.5x=-11
divide both sides by 3.5
x=-3.14
or -3 with -.5 remainder
Answer:
x=-22/7
Step-by-step explanation:
multiply 3.5 and x then multiply 3.5 and 2. this will get you 3.5x+7=-4. next you need to subtract the 7 from the -4, resulting in 3.5=-11. finally divide -11 and 3.5, after that you get the answer of x=-22/7 or -3 1/7. if you need decimal form that will be -3.142857
Lancé le 26 novembre 2011, le Rover Curiosity de la Nasa est chargé d'analyser la planète Mars. il a atterri sur la planète rouge le 6 août 2012, parcourant ainsi une distance d'environ 560 millions de kilomètres en 255 jours. quelle est la durée du vol?
Answer: La durée de la vol entire est 560 millions de miles. La durée par hour est 2.19 millions de miles par hour.
Step-by-step explanation: Je ne sais pas sûr que Je comprends la question exactement. Si on doit trouver la durée par hour, il faut divider 560000000 par 255.

what is the value of (4x-5)-(3x-10)
Answer:
-5
Step-by-step explanation:
Identify the x- and y-intercepts of the equation
4x - y = 8
[tex]\boxed{\boxed{\pink{\sf \leadsto The \ x - intercept \ is \ (2,0) \ \& \ the \ y \ intercept \ is \ (-8,0) }}}[/tex]
Step-by-step explanation:A linear equation is given to us and we are required to find x and y Intercepts to it. So the given linear equation to us is ,
[tex]\bf \implies 4x - y = 8 \\\\\bf\implies \dfrac{1}{8} \bigg( 4x -y\bigg) =\frac{1}{8}\times 8 \\\\\bf\implies \dfrac{4x}{8}-\dfrac{y}{8} = \dfrac{8}{8} \\\\\bf\implies \dfrac{x}{2}-\dfrac{y}{8}=1 \\\\\bf\implies\boxed{\red{\bf \dfrac{x}{2}+\dfrac{y}{-8}=1 }}[/tex]
Hence on comparing to standard form we get
x intercept as (2 , 0 )y intercept as (0,-8) Hence the x - intercept is ( 2 , 0 ) and the y - intercept is ( 0 , -8 ) .Answer:
x = (2,0)
y = (0,-8)
Step-by-step explanation:
Remember than an intercept always has the other number as 0.
Let's put this in standard form of a linear equation, or y = mx + b
4x - y = 8
-y = -4x + 8
y = 4x - 8
"b" is the y intercept. The y intercept is -8, or (0,-8)
Now, to find the x intercept, all we have to do is substitute 0 for y.
0 = 4x -8
8 = 4x
2 = x
The x intercept is 2, or (2,0)
