10z^2-2z-2
10x3^2-2x3-2
90-6-2
90-8
82
Answer:
82
Step-by-step explanation:
Evaluate 10z² - 2z - 2 where z = 3:
[tex] \longrightarrow [/tex] 10z² - 2z - 2 = 10 × 3² - 2 × 3 - 2
3² = 9:
[tex] \longrightarrow [/tex] 10 × 9 - 2 × 3 - 2
10 × 9 = 90:
[tex] \longrightarrow [/tex] 90 - 2 × 3 - 2
-2 × 3 = -6:
[tex] \longrightarrow [/tex] 90 - 6 - 2
90 - 6 - 2 = 90 - (6 + 2):
[tex] \longrightarrow [/tex] 90 - (6 + 2)
6 + 2 = 8:
[tex] \longrightarrow [/tex] 90 - 8
[tex] \longrightarrow [/tex] 82

Answer:
So all the possible solutions are:
[tex]\bold{523,~400,~379~and,~378.6}[/tex]Solution Steps:
First you need to solve the real inequality to understand how to find the rest of the possible equations.
Add 78 to both sides:
[tex]78+78=[/tex] Cancels Out[tex]300+78=378[/tex]So now we know the real answer, but it ask for all possible answers.
(Means anything larger than 300 when you plug it into x - 78 > 300.)
Numbers that are greater than 378:
1.) [tex]377-78=299 > 300[/tex] (False)
2.) [tex]523-78=445>300[/tex] (True)
3.) [tex]0-78=-78>300[/tex] (False)
4.) [tex]-62-78=-140>300[/tex] (False)
5.) [tex]400-78=322>300[/tex] (True)
6.) [tex]379-78=301>300[/tex] (True)
7.) [tex]222-78=144>300[/tex] (False)
8.) [tex]378.6-78=300.6>300[/tex] (True)

During geometry class, students are told that ΔTSR ≅ ΔUSV. Marcus states that ΔTSR is mapped to ΔUSV by performing a rotation about point S. Sam states that ΔTSR is mapped to ΔUSV by a reflection across the line that goes through point S. Determine if either student is correct.
Answer: Marcus is correct.
i got it right on Edge2020
Step-by-step explanation:
Transformation involves changing the position of a shape through translation, dilation, rotation and reflection.
Marcus's claim is correct.
The triangles are given as: ΔTSR and ΔUSV
By comparison, we can see that point S is on both triangles, and this point on both triangles corresponds.
So, to map ΔTSR to ΔUSV, then ΔTSR must be rotated about point S to ΔUSV or rotate ΔUSV about point S to ΔTSR.
Hence, Marcus is correct, and Sam is not.

Answer:
m = 1/3
Step-by-step explanation:
Answer:
Slope can be indentified by looking t how much a point has gone up/down and to the right/left. An example can be a point at 0,0 and a point at 1,1
from 0,0 to 1,1 it goes 1 units up and 1 unit right. Therefore the slope is 1/1 or just 1.
So to find this answer we could graph the points or just find out how many units it takes from going up/down and right/left to get from (-2, 1) to (7, 4)
From -2 to 7 is 9 units and from 1 to4 is 3 units
The slope is rise/run meaning the distance u moved in height over he distance moved right/left. Therefore the slope is 3/9 which is 1/3

Find the greatest solution to the following system of equations. Write as x= ?
y=x^2+x-2 and y=-x+1
Answer:
we have x=1, y=0 and x=-3, y=4
Step-by-step explanation:
We need to solve the equations: [tex]y=x^2+x-2 \ and \ y=-x+1[/tex]
Let:
[tex]y=x^2+x-2--eq(1)\\ y=-x+1---eq(2)[/tex]
Putting value of eq(2) into eq(1)
[tex]-x+1=x^2+x-2\\Solving:\\x^2+x-2+x-1=0\\x^2+2x-3=0\\Factorising:\\x^2+3x-x-3=0\\x(x+3)-1(x+3)=0\\(x-1)(x+3)=0\\x-1=0 \ or \ x+3=0\\x=1 \ or \ x=-3[/tex]
Now finding values of y for x=1 and x=-3
[tex]For \ x=1, \\y=-x+1 \\y=-1+1 \\y=0\\For \ x=-3\\ y=-x+1\\y=-(-3)+1 \\y=3+1\\y=4[/tex]
So, we have x=1, y=0 and x=-3, y=4

What does it mean if (2, 20) is a solution of y = 10x and x +y = 22 ?
2, 20) makes exactly one of the equations true.
(2, 20) makes at least one of the equations true.
(2, 20) makes neither equation true.
(2, 20) makes both equations true.
Answer:
(2, 20) makes both equations true
Step-by-step explanation:
If a point is a solution for 2 equations, that means that it makes both equations true.
So, since (2, 20) is a solution to both y = 10x and x + y = 22, that means it makes both of the equations true.
