System of equations!!!
Answer:
Step-by-step explanation:
1. x^2-x-20=3x-15
x=5, x=1 substitute
y=3*5-15 = 0
y=3*(-1)-15 = -18
Solution: (5,0) & (-1,-18)
2. x^2+2x+3=x+5
x=-2, x=1 substitute
y= -2+5 = 3
y=1+5 = 6
Solution: (-2,3) & (1,6)

Answer:
C. [tex]y = - \frac{1}{4} x - 2[/tex]
Step-by-step explanation:
To find slope using coordinates, use the formula above.
[tex](4, - 3) \: (0, - 2)→ \frac{ - 2 - ( - 3)}{0 - 4}→ \frac{ - 2 + 3}{ - 4} → - \frac{1}{4} [/tex]
Now, using the [tex]y = mx + b[/tex] formula, plug in [tex] - \frac{1}{4} [/tex] as [tex]m[/tex] (slope) and either coordinate as the [tex]x[/tex] and [tex]y[/tex] values. It looks like this:
[tex] - 3 = - \frac{1}{4}(4) + b[/tex]
To solve for [tex]b[/tex], continue to use PEMDAS.
[tex] - 3 = - \frac{1}{4}(4) + b→ - 3 = - 1 + b→ - 2 = b[/tex]
Now use [tex]m[/tex] and [tex]b[/tex] to solve for your equation:
[tex]y = - \frac{1}{4} x - 2[/tex]
The answer is C.

Imagine making slices through the solid parallel to the bases. What two-dimensional shapes are formed
Answer:
shape as that of the base of the solid
Step-by-step explanation:
A solid has a three dimensional shape. A three dimensional shape has both length, breadth and height. If the solid is being cut parallel to the base, a two dimensional shape (has length and width) is formed.
The shape of the two dimensional shape is the same as the shape of the base. Hence if solid is cut parallel to the bases, the shape formed would have the same shape as that of the solid base.
if you can please answer the first and other question bc i dont know if im right lol
Answer:
DB!
Step-by-step explanation:
Question 1: A rectangle's area is length x width. You add up all the portions for the full area.
Question 2: A rectangle's area is length x width. a is the width and the length is 2+3+4, so the area is a(2+3+4)

Pls help with #6 pls pls!!!
Answer:
Answers in explanation.
Step-by-step explanation:
Finding angle 1:
52 + angle 1 = 180
angle 1 = 128
Finding angle 2:
128 (angle 1) + angle 2 = 180
angle 2 = 52
Finding angle 5:
52 + 47 + angle 5 = 180
angle 5 = 81
Finding angle 3:
angle 2 + angle 3 + angle 5 = 180
52 + angle 3 + 81 = 180
angle 3 = 47
Finding angle 4:
angle 3 + angle 4 = 180 OR angle 4 + 47 = 180
47 + angle 4 = 180
angle 4 = 133

Explain the steps of graphing 2x + 4≤ 12.
Answer:
Step-by-step explanation:
First, you want to simplify so the equation would be x+2≤6 or x≤4
Because you are solving for x you want to graph a vertical line on 4.
Then you shade on the left side of the line because it is less than or equal to. If it were just less then you would do a dashed line on 4 but because it is also equal to 4 then you keep it a solid line.
I recommend using Desmos graphing calculator.

A third line goes through the same point. How would that show up in a table representing the relationship for the third line?
Answer:
Most likely the table will contain one pair of values that correspond to the coordinate where the previous lines intersect.
Step-by-step explanation:
It may be possible that the table before the third line contains values on either side of the point of intersection, but the slope will produce a line that connects those values and passes through the previous intersection.

James paid an initial fee of $6.00 for a movie rental service. Each time he rents a movie he is charged $2.00. Sarah uses a different movie
rental service that charges based on the equation y = 3x + 4, where y is the total cost and x is the number of movies rented. At what point
are the prices of the two services the same?
606
Answer:
We have system of equations
James's total cost: Y = 2x + 6 (1)
Sarah's total cost: Y = 3x + 4 (2)
replace y = 2x + 6 and (2) => 2x + 6 = 3x + 4 => x = 2 => y = 10
So the total cost of renting movies by James And Sarah is equal

In one part of a kennel, 5/8 of the 24 dogs are male. In another part of the kennel, 4/5 of the 30 dogs are male.
How many male dogs are in the two parts of the kennel?
Answer:
39
Step-by-step explanation:
The computation of the number of male dogs in the two parts of the kennel is shown below:
In one part, the male dogs are
= 24 × 5 ÷ 8
= 15
In the another part, the male dogs are
= 30 × 4 ÷ 5
= 24
So, the total male dogs is
= 15 + 24
= 39

Answer:
C. {-9,-3}
Step-by-step explanation:
[tex]|k+6|=3[/tex] gives [tex]k+6=3[/tex] if [tex]k + 6 \geq 0[/tex]. This gives [tex]k=-3[/tex], which is valid.
It can also give [tex]-(k+6) = 3[/tex] if [tex]k + 6 < 0[/tex]. This gives [tex]k=-9[/tex], which is valid.
Hence the solutions are [tex]k=-9 \vee k=-3[/tex].
