Answer: no
Step-by-step explanation:
A jet and a light plane leave the same airport at the same time and travel in opposite directions at 960 km/h and 560 km/h, respectively. In how many hours will they be 4560 km apart?
The jet travels a distance of
(960 km/h) t
after time t, while the light plane travels a distance of
(560 km/h) t
The jet is faster than the light plane, so the distance between them is
(960 km/h) t - (560 km/h) t = (400 km/h) t
so the time it takes for them to be 4560 km apart is
(400 km/h) t = 4560 km
==> t = (4560 km) / (400 km/h)
==> t = 11.4 h

The graph of y = -3x + 4 is:
Answer:
(0,4)
Step-by-step explanation:
What is the equation, in slope-intercept form, of the line that passes through (0, 6) and has a slope of 4 (5 points)
Answer: y=4x+6
Step-by-step explanation: you replace the variables in the equation with the variables in the point given to find b.
Answer:
[tex]y = 4x+6[/tex]
Step-by-step explanation:
Equation of a line
The equation of a line can be written in the form:
[tex]y = mx+b[/tex]
Where m is the slope of the line and b is the y-intercept. We are given the value of m=4, thus the equation becomes:
[tex]y = 4x+b[/tex]
To find the value of b, we use the point (0,6):
[tex]6=4*0+b[/tex]
Solving:
[tex]b=6[/tex]
Thus, the equation in slope-intercept form of the required line is
[tex]\boxed{y = 4x+6}[/tex]

Kate has $7 in her lunch account. She spends $3 each day on lunch for 5 days. What
is the balance of her lunch account after the 5th day?
Answer:-7
Step-by-step explanation:
Answer:
$-8
Step-by-step explanation:
Subtract 3 from 7 for the first day. She has $4 left
Subtract 3 from 4 for the second day. She has $1 left
Subtract 3 from 1 for the third day. She has $-2 left
Subtract 3 from -2 for the fourth day. She has $-5 left
Subtract 3 from -5 for the fifth day. She has $-8 left in her lunch account

find x,y,and z if AB||CD
Step-by-step explanation:
Hey there!
75° + 28° + angle KFG = 180°( being linear pair)
103° + angle KFG = 180°
angle KFG = 180° - 103°
Therefore, angle KFG= 77°
Now;
angle KFG + 28° +22° + X= 180°{ co-interior angle}
77°+28° + 22°+x= 180°
X = 180°-127°
Therefore, X = 53°
y == X+22°= 75° { being alternate angle}
angle KFG+x+z = 180° {sum of interior angle of triangle}
77°+53° + z = 180°
z = 180° - 130°
z= 50°
Therefore, X= 53°, y = 75° and z= 50°.
Hope it helps...
The area of a rectangle is x²-4x-21
Write down an expression for the width and the length of
the rectangle.
Answer:
Step-by-step explanation:
Area of rectangle= Length x Width
and the given Area is a quadratic expression
A=[tex]x^{2} -4x-21[/tex]
We use the factorization method so,
we need 2 numbers that when multiplied we get -21 and when we add/subtract we get -4 so,
A=[tex]x^{2} -7x+3x-21[/tex]
now we simplify,
A=[tex]x(x-7)+3(x-7)[/tex]
A=[tex](x-7)(x+3)[/tex]
This looks familiar doesn't it, when we write the formula for the area of rectangle its
A= Length x Width and the equation here shows that
A= [tex](x-7)(x+3)[/tex]
So the expression for the length is x-7 and
the expression for the width is x+3 i think u have missed maybe some information on the question as such that the perimeter might be missing because length could be either x-7 or even x+3 same goes for width maybe someone can correct me if im wrong
Janice is roller skating at a constant speed away from her house. The first half of the street is flat, but the second half has a steep upward hill. Janice moves more slowly as she skates up the hill.
Which graph shows Janice's position as she roller skates away from her house?
A. Z
B. X
C. W
D. Y
Answer:
It's Z.
Step-by-step explanation:
Because the road is straight at first, then it gets steep.
which means that the road goes down,
kinda like a drop off.
Answer:
Y moving quicker, then moving slower rate
which is the first step in simplifying the expresion 2(x+3)+5?
Answer:
[tex]2x + 11[/tex]
Step-by-step explanation:
1) Expand by distributing terms.
[tex]2x + 6 + 5[/tex]
2) Collect like terms.
[tex]2x + (6 + 5)[/tex]
3) Simplify.
[tex]2x + 11[/tex]
The first step to do this equation is to expand.which means to solve whats inside the parentheses first. If you expand you'll get a answer of 2x + 11.

Find 3 ratios that are equivalent to the given ratio. 6/9
Answer:
2:3
12:18
18:27
Step-by-step explanation:
Answer:
In order to get equivalent ratios, we can just multiply by a factor! Lets use the factors of 2, 3, 4.
So we have:
[tex]2 * \frac{6}{9}=\frac{2*6}{2*9}=\frac{12}{18}[/tex]
As well as:
[tex]3 * \frac{6}{9}=\frac{3*6}{3*9}=\frac{18}{27}[/tex]
And finally:
[tex]4 * \frac{6}{9}=\frac{4*6}{4*9}=\frac{24}{36}[/tex]

Which expression describes the area in square units of a rectangle has a width of 4x^3y^2 and a length of 3x^2y^3
Area is length x width:
4x^3y^2 x 3x^2y^3
Apply the exponent rule: a^b x a^c = a^(b+c)
4 x 3 = 12
x^3 x x^2 = x^5
y^2 x y^3 = y^5
Combine for final answer: 12x^5y^5
What is the answer to 6x + 7= -x + 70
Answer:
x = 9
Step-by-step explanation:
6x + 7 = -x + 70
~Subtract 7 to both sides
6x = -x + 63
~Add x to both sides
7x = 63
~Divide 7 to both sides
x = 9

can you make an irrational number, a rational number and if possible, how?
Answer:
The sum of two irrational numbers, in some cases, will be irrational. However, if the irrational parts of the numbers have a zero sum (cancel each other out), the sum will be rational.
