Answer:
t = 6 hours
Step-by-step explanation:
D = r x t
1920 = 320t
divide both sides by 320:
t = 6 hours
3x + y = 4
8x + 2y = 10
Answer:
I take it that we solve for x and y, so we have
3x + y = 4, so we have y = 4 - 3x
and plug that in to
8x + 2y = 10
8x - 6x + 8 = 10
so
2x = 2
x = 1
y = 4 - 3
y = 1

So, if ya wanna solve this question and of course questions alike, ya gotta pay attention to the graph. mean All of these parabolic chart have the domain of R
Step-by-step explanation:
So there ya go
D=R
and now bout the range ya gotta find the vertex, which is:
[tex] x = \frac{ - b}{2a} \: \: y = \frac{Δ}{4a} [/tex]
now pay attention
X=2/–2=–1
y=–(–1)²–2(–1)+3=4
Now the highest point of your parabolic chart is 4 and the lowest point is endless which is (–♾,4]
Well, finally your answer is D

suppose that grade point averages of undergraduate students at one university bell-shaped distribution with a mean of 2.57 and a standard deviation of 0.4 describe where approximately 99.7% of a grade point averages lie
Answer:
2.57-0.4-0.4-0.4=1.37
2.57-0.4-0.4=1.77
so the answer is 1.37 between 3.77

if (x/3+1,y-2/3)is equal to (5/3,1/2) find the value of x and y
Answer:
The value of x is 2.
The value of y is [tex]\frac{7}{6}[/tex]
Step-by-step explanation:
x:
We have that:
[tex]\frac{x}{3} + 1 = \frac{5}{3}[/tex]
Multiplying everything by 3
[tex]x + 3 = 5[/tex]
[tex]x = 2[/tex]
The value of x is 2.
y:
We have that:
[tex]y - \frac{2}{3} = \frac{1}{2}[/tex]
Least common multiple between 3 and 2 is 6, which means that we multiply everything by 6.
[tex]6y - 4 = 3[/tex]
[tex]6y = 7[/tex]
[tex]y = \frac{7}{6}[/tex]
The value of y is [tex]\frac{7}{6}[/tex]

Someone answer and explain ILL MARK BRAINLIEST!!!
Answer:
x=1, y=-2
Step-by-step explanation:
2x-3y=8 (1)
4x+3y=-2 (2)
From (1):
2x=8+3y
x=4+1.5y (3)
Subst (3) into (2)
4(4+1.5y)+3y=-2
16+6y+3y=-2
16+9y=-2
9y=-2-16
9y=-18
y=-2
subst y=2 in to (3)
x=4+(1.5*-2)
x=4-3
x=1
Ans: x=1, y=-2

Find the roots/zeroes of the following polynomial
x^2−19=6
Answer:
x=5 and x=-5
Step-by-step explanation:
1. first you would subtract 6 from both sides to set the equation = to zero.
2. The equation would then be x^2-25=0.
3. that is a difference of two squares polynomial. So when you factor it, it is (x+5)(x-5)=0
4. by the zero product property, the roots are 5 and -5.
Is the slope for the line below positive or negative
Answer:

Find the Area of the Shaded Region.
Round to the nearest tenth if necessary.
18 m
25 m
5 m
50 m
9514 1404 393
Answer:
610 m²
Step-by-step explanation:
If we extend the horizontal line across the right-hand portion of the figure, then the figure is divided into two rectangles:
bottom: 5 m × 50 m = 250 m²
top: 18 m × 20 m = 360 m²
The sum of these areas is the shaded area:
shaded area = 250 m² +360 m² = 610 m²
