Answer:
x + y = 32
x = y + 8
Step-by-step explanation:
Sum of two numbers is 32:
x + y = 32
One number is 8 more than the other:
x = y + 8
5x - 4y = -10
y = 2x - 5
2 =
y =
Answer:
x=10
y=15
Step-by-step explanation:
Since we know y in terms of x, we can use substitution and say instead of-
5x-4y=-10
5x-4(2x-5)=-10
5x-8x+20=-10
-3x=-30
x=10
Substitute x into the equation-
y=2x-5
y=2(10)-5
y=20-5=15.

What is the first step for plotting points on the coordinate plane
Answer:
Steps for Plotting an Ordered Pair (x, y) in the Coordinate Plane. Determine the x-coordinate. Beginning at the origin, move horizontally, the direction of the x-axis, the distance given by the x-coordinate. If the x-coordinate is positive, move to the right; if the x-coordinate is negative, move to the left.
An airplane flies with a constant speed of 620 miles per hour. How long will it take to
travel a distance of 310 miles? Give your answer in minutes or hours.
Answer:
30 minutes
Step-by-step explanation:
Alright lets start by laying out what the problem gives us :
A plane flies 620 mph.
It is asking how long it will take to travel 310 miles.
We need to give our answer in minutes or hours.
So lets take mph and look at the full meaning "Miles per hour"
An hour has 60 minutes in it.
So really it is saying miles per 60 minutes as well as miles per hour
So you could say the plane is traveling 620 miles every 60 minutes.
So now lets look at the number 310.
Just looking at it I can tell you that 310 looks very close to half of 620, in fact it is exactly half!
So lets divide the 620 mph by the 310 miles it is asking and we get 2! Proving that 310 is half of 620.
Alright now lets divide both the number of miles and number of minutes :
620 miles per 60 minutes
divided by 2 both miles and minutes
310 miles per 30 minutes
So this is your answer. After this you get that it would take 30 minutes to travel 310 miles in a plane going 620 miles per hour!
I hope this helps and I could help you understand it. :)

Find the slope and y-intercept of the line represented by the table.
.
Please help me
Step-by-step explanation:
I cant see the question but use the formula
y=mx+b
m=slope
b=y-intercept
you can also use the equation
y2-y1/x2-x1 to find slope.
since its a table, you can plug the x (input) and y (output) coordinates of the table to find the slope.
Write a quadratic function in vertex form whose graph has the vertex ( -5. - 1) and passes through the point (-2.2).
Answer:
[tex](\frac{1}{3})(x+5)^2-1[/tex]
Step-by-step explanation:
So first let's write a graph in vertex form with a vertex of (-5, -1)
We get
a(x+5)²-1
We now need to determine a
we know that when x= -2 y=2 which means we have
a(-2+5)²-1=2
Solve for a
a(3)²=3
9a=3
a=3/9
a=1/3
Now that we know what a is equal to we can write our equation
[tex](\frac{1}{3})(x+5)^2-1[/tex]

Veronica cut a triangular piece of cookie cake with side lengths that measure 3.6 cm, 6 cm and 4.8cm.
Did Veronica cut out a right triangle?
Answer:3.6 + 4.8 > 6
Step-by-step explanation:
The answer is YES, the triangle that is cut down by Veronica is a right triangle.
What is a triangle?The basic polygonal shape of a triangle has three sides & three interior angles. This is one of the fundamental shapes in geometry and is particularly associated. It has three connected vertices. Triangles can be divided into a variety of categories according to their sides and angles.
As per the given information in the question,
The lengths of the sides of the triangle are given as,
Let Base, b = 3.6 cm
Perpendicular, p = 4.8 cm
Hypotenuse, h = 6 cm
Now, use the equation of Pythagoras' theorem,
h² = p² + b²
6² = 4.8² + 3.6²
36 = 23.04 + 12.96
36 = 36
It satisfies Pythagoras' theorem, which means that it is a right triangle.

4 (X + (-1))
(4 x + 5)
4 (x + 1)
(5 - 4x)
Answer:
4(x + 1) and 4(x - (-1))
Step-by-step explanation:
4(-1 + 1) = 4(0) = 0
(4 (-1) + 5) = -4 +5 = -1
4(-1 - 1) = 4(-2) = -8
(5 - 4(-1)) = 5 + 4 = 9
4(-1 - (-1)) = 4(0) = 0
