What is the y-intercept of the equation 4x + 5y = 20?
(0,4)
(0,5)
(4,0)
(5,0)
Answers
Answer:
(0,4)
Step-by-step explanation:
4x+5y=20
5y=20-4x
y=4-4/5x
y-intercept means a point on the y-axis(x=0)
y=4-4/5x
y=4-4/5(0)
y=4
Therefore, y-intercept is at (0,4)

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

The ongoing profundity of the hole is less than the negative region feet subterranean level. Then the right choice is D.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
A hole needs to arrive at no less than 72 feet subterranean level. This implies it should be multiple 1/2 times its ongoing profundity. This profundity is addressed by the imbalance 4 ¹/₂ d < - 72, where d is the ongoing profundity of the burrow.
4 ¹/₂ d < - 72
Simplify the inequality, then we have
4 ¹/₂ d < - 72
4.5d < - 72
d < - 72 / 4.5
d < - 16
The ongoing profundity of the hole is less than the negative region feet subterranean level. Then the right choice is D.

Answer 1a 18 1b 36 1c 648
1a : if you look at the shape you will see its made of squares. I counted the squares, its 18.
1b : one side is 6 in. since its a square all sides are equal. so multiply 6 by 6 to get 36.
1c : this one is easy. We take the number of squares across the surface (18) by the area of each square (36) it is 648.

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

A store regularly sells a Nintendo Switch Lite for $200. They are currently on sale for 30% off and in your state the sales tax is 8%. What would be the final cost for the consumer (including tax) if they buy the Nintendo Switch Lite?
Answers
Answer:
$151.20
Step-by-step explanation:
The sale price of the Nintendo Switch Lite is 30% off its regular price of $200, which means the discount is:
Discount = 30% x $200 = $60
The sale price of the Nintendo Switch Lite after the discount is:
Sale price = $200 - $60 = $140
The sales tax in the state is 8%, so the tax amount on the sale price is:
Tax amount = 8% x $140 = $11.20
Therefore, the final cost for the consumer, including tax, would be:
Final cost = Sale price + Tax amount = $140 + $11.20 = $151.20
Hence, the final cost for the consumer, including tax, would be $151.20 if they buy the Nintendo Switch Lite.
200 x 30% is 60 then i guess you subtract 60 from 200 which is 140 then im pretty sure you multiply the sales tax aka 8% to 140 which would be 8% x 140 = 11.2 then you add 11.2 to 140 and i think that gives you 151.2
A glide reflection is a transformation that is made up of a translation and a reflection across a line the is parallel to the direction of the translation.
A. Graph triangle DEF with vertices D(1,-1) E(7,-3) F(2,-7)
B. Graph triangle DEF under a glide reflection where the translation is (x,y) —> (x, y+8). Give the coordinates of the vertices of the image.
C. Are the two figures congruent?
Answers
Answer:
m
Step-by-step explanation:k
The vertices of the image triangle after the glide reflection are D'(1, 7), E'(7, 5), F'(2, 1) and both the triangles are not congruent
Graph of triangle DEF with vertices D(1,-1), E(7,-3), F(2,-7):
To graph the triangle, plot the given coordinates on a coordinate plane and connect the points to form a triangle.
D(1,-1), E(7,-3), F(2,-7)
Graph of triangle DEF under a glide reflection where the translation is (x,y) —> (x, y+8):
To perform the glide reflection, we first apply the translation by adding 8 to the y-coordinate of each vertex, and then we reflect the resulting triangle across a line parallel to the direction of the translation.
Translation: (x,y) —> (x, y+8)
Applying the translation to the original triangle DEF:
D(1, -1+8) = D(1, 7)
E(7, -3+8) = E(7, 5)
F(2, -7+8) = F(2, 1)
Now we have the new vertices for the translated triangle:
D(1, 7), E(7, 5), F(2, 1)
Next, we reflect this translated triangle across a line parallel to the direction of the translation. Since the direction of the translation is vertical, the reflection line will also be vertical.
The resulting image triangle after the glide reflection will have the same vertices as the translated triangle, but mirrored vertically.
The vertices of the image triangle after the glide reflection are:
D'(1, 7)
E'(7, 5)
F'(2, 1)
The original triangle DEF and the image triangle after the glide reflection are not congruent.
