Answer:
y=5x+4
Step-by-step explanation:
You would have to look up how to do the hadn written way of figuring out this but I just used my calculator. To do this with your TI-84 or newer calculator, press "stat" and go into "edit". You will see some columns with the names "L1, L2, L3, etc." which stand for lists. put your x values in "L1" and their corresponding y values next to them in "L2". When you're done press stat again and move right to the heading "Calc". Go down to number 4 which should say "LinReg(ax+b)" next to it and press enter. now you should see "Xlist" and "Ylist" with "L1" and "L2" beside them respectively. Once that is set, go down to "Calculate" and press enter and it should give you slope intercpet form and what "a" and "b" are. You're welcome.~ ;P

What is the equation of this graphed line?
Answer:
[tex]y=-\frac{9}{8} x+7[/tex]
Step-by-step explanation:
The slope is found by doing the equation [tex]\frac{rise}{run}[/tex]. When looking at the first two points, it's shown that the rise (difference between the two y values) is -9 (since it decreased by 9) and the run (difference between the two x values) is 8 (since it increased by 8). This makes the slope equal [tex]-\frac{9}{8}[/tex].
The y intercept is found by looking at the y value when x = 0. In this picture, it is clear that it is 7.
The equation you want to use is y = mx + b , where b is the y intercept and m is the slope. Just plug in the numbers and you got your equation!

Which pair of numbers has the greatest GCF?
A = 140 and 210
B = 130 and 390
C = 240 and 320
D = 550 and 880
In the figure shown, which theorem can be used to show that ABC = ADEF?
O A The triangles are not congruent.
OB SAS Triangle Congruence Theorem
OC AAS Triangle Congruence Theorem
OD ASA Triangle Congruence Theorem
Pick choice-C ... AAS.
When I learned Geometry (during the late Pleistocene epoch), I don't remember ever using AAS.
BUT ... If you know 2 angles of a triangle, then you know all three, because they all add up to 180.
So if you have AAS=A'A'S', then you also have ASA=A'A'S', which was a congruence theorem even way back then.
Ahhh the good old days. We rarely got any homework, because the teachers all knew that the clay tablets would ruin our backpacks.

what is the value of this expression below when z=3
10z^2-2z-2

82
Step-by-step explanation:
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

15 is answer.
Find the slope of the line passing though points (-7, 8) and (5, -7).
Answer:
13/13= Slope = 1
Step-by-step explanation:
M=rise/run, So that means 13 down then 13 to the left.
So 13/13 is the slope, but if it is simplified it is slope=1
Substitution method
3x+2y=15
y=6x
Answer:
x = 1
Step-by-step explanation:
3x +2y = 15
y = 6x
Substitute y for 6x in 3x +2y = 15!
3x + 2(6x) = 15
3x + 12x = 15
Combine like terms
15x = 15
Divide both sides by 15
15x = 15
x = 1

Geoff has had, for a long time, a savings account with an annual interest rate of 3.65%. Now, however, the bank wants to change his rate to 0.3% monthly. Should Geoff accept this change?
Answer:
No

Answer:

Step-by-step explanation:
we can say that AD is congruent to DC
so your equation for x is: 4x - 1 = 2x
solve this to get x = 0.5
plug x into and equation and multiply you answer by 2 to find the hypotenuse of triangle ABC and DEF
4(0.5) - 1 = 1
hypotenuse: 1 x 2 = 2
since we know x is 0.5, plug this into 4x + 1 to find the length of the leg FE,
4(0.5) + 1 = 3
In the diagram, it shows that the legs of triangle are congruent
this means that FE, ED, BA, and BC are all congruent
since we know FE is 3, we know that all the other sides are 3 as well
this means that the perimeter of the triangle is: leg + leg + hypotenuse
so 3 + 3 + 2
the perimeter is 8
yeah so can u help me
Answer: 5 - 9 = -4
Step-by-step explanation:
So 0 represents your starting point. The arrow starting at 0 is going to the right, so it's adding. It ends at 5, so that means the problem begins with 5. The next arrow starts at 5, then goes back to -4, going back 9 spaces. So far we have 5 - 9. It all stops at -4, so that makes it 5 - 9 + -4.
20 pointsBRAINLEST!!!!!!!!!! and PointsAfter an accident, police can use the formula v=25L to estimate the speed, v, in miles per hour, that a car was traveling by measuring the length of the skid marks, L, in feet. Estimate the speed of a car that left skid marks 118 ft long. If the posted speed limit is 45 mi/h, was the car speeding? The speed of a car that left skid marks 118 ft long was about nothing mi/h.
The correct format of the question is
After an accident, police can use the formula [tex]v=2\sqrt{5L }[/tex] to estimate the speed, v, in miles per hour, that a car was traveling by measuring the length of the skid marks, L, in feet. Estimate the speed of a car that left skid marks 118 ft long. If the posted speed limit is 45 mi/h, was the car speeding? The speed of a car that left skid marks 118 ft long was about nothing mi/h.
Answer:
48.6mi/h, Yes the car was speeding.
Step-by-step explanation:
The speed of the car is given by [tex]v=2\sqrt{5L }[/tex]
Skid length (L) = 118ft
V= [tex]2\sqrt{5*118}[/tex]
= 2 [tex]\sqrt{590}[/tex]
= 2*24.3
V = 48.6mi/h
Since the speed limit is 45mi/h and the velocity of this driver is 48.6mi/h it is clear that was speeding by 3.6mi/h over speed limit.
Which statement(s) could be used in a proof with the reason CPCTC after proving ΔABC≅ΔEFG? (Check all that apply) *
AC ≅ EG
AB ll EF
BC ≅ FG
∠BCA ≅ ∠FGE
∠CBA ≅ ∠GEF
Answer:
The statements(s) that could be used in a proof with the reason Corresponding Parts of Congruent Triangles are Congruent (CPCTC) are;
AC ≅ EG
BC ≅ FG
∠CBA ≅ ∠GEF
Step-by-step explanation:
CPCTC is a phrase that stands for Corresponding Parts of Congruent Triangles are Congruent. It can be used as a bases for congruent relationships of corresponding angles and segments, after two triangles have been proven as congruent
Given ΔABC is congruent to ΔEFG, we have by CPCTC;
Side AB ≅ Side EF
Side AC ≅ Side EG
Side BC ≅ Side FG
∠A ≅ ∠E
∠B ≅ ∠F
∠C ≅ ∠G.
For each equation, determine whether it has no solutions, exactly one solution, or is true for all values of x (and has infinitely many solutions). If an equation has one solution, solve to find the value of x that makes the statement true.
6 x + 8 = 7 x + 13
6 x + 8 = 2 ( 3 x + 4 )
6 x + 8 = 6 x + 13
Answer:
Equation 1 has exactly one solution.Equation 2 has infinitely many solutions.Equation 3 has no solution.Step-by-step explanation:
We are given three equations to solve. First, let's solve the equations for x.
Equation 1
[tex]\displaystyle{6x+8=7x+13}\\\\7x + 13 = 6x + 8\\\\x + 13 = 8\\\\\bold{x = -5}[/tex]
Therefore, we determined that for the first equation, x = -5. We can check our solution by substituting it back into the original equation.
[tex]\displaystyle{6(-5)+8=7(-5)+13}\\\\-30 + 8 = -35 + 13\\\\-22 = -22 \ \checkmark[/tex]
Since we got a true statement, there are no other values of x for which we get a true statement. Let's test this with the opposite value: positive 5.
[tex]6(5)+8=7(5)+13\\\\30 + 8 = 35 + 13\\\\38 = 48 \ \text{X}[/tex]
Therefore, for Equation 1, there is exactly one solution.
Equation 2
[tex]6 x + 8 = 2 ( 3 x + 4 )\\\\6x + 8 = 6x + 8\\\\0 + 8 = 8\\\\8 = 8 \ \checkmark[/tex]
We get a true statement by solving for x (which ends up canceling out of the equation entirely). Therefore, we can check any value in place of x to see if we get a true statement. For this instance, I will use -3.
[tex]6(-3) + 8 = 2 ( 3(-3) + 4 )\\\\-18 + 8 = 2(-9+4)\\\\-18 + 8 = 2(-5)\\\\-18 + 8 = -10\\\\-18 = -18 \ \checkmark[/tex]
We still get a true statement, so Equation 2 has infinitely many solutions.
Equation 3
[tex]6 x + 8 = 6 x + 13\\\\0 + 8 = 13\\\\8 \neq 13[/tex]
We get a false statement. Therefore, Equation 3 has no solution.
