Find the slope of the line that passes through
(7,-1) and (9,0)
Answer:
1/2 or 0.5
Step-by-step explanation:
so to find the slope of two points you use the slope formula which is rise over run, y2-y1/x2-x1. so that would be -1-0/7-9. leading to -1/-2. so the slope is 1/2 or 0.5.

HELP “The vertical supports in this truss bridge are built so that
AABO=AOCD. Which of the following statements
is NOT true?”
Answer:
The statement that is not true is;
c) m∠ABO = m∠ODC
Step-by-step explanation:
With the assumption that the lengths AO, and OD are equal, we have that in ΔABO and ΔOCD, the following sides are corresponding sides;
Segment AO on ΔABO is a corresponding side to segment OD on ΔOCD
Vertices B and C on ΔABO and ΔOCD are corresponding vertices
Therefore;
Segments AB and OB on ΔABO are corresponding sides to segments OC and OD on ΔOCD respectively
Therefore, ∠ABO on ΔABO is the corresponding angle to ∠OCD on ΔOCD
Given that ΔABO ≅ ΔOCD, we have that ∠ABO ≅ ∠OCD
Therefore;
m∠ABO = m∠OCD by definition of congruency

Answer:
I believe D is the answer
Step-by-step explanation:
how I find the slope it by looking at the y-axis and what hits directly on that line. you can see that 3 hits directly on that line so the b in y=mx+b is three which is your starting point. then you follow the line and see where it hits directly on a point. then count the blocks. remember that it's rise over run so that's y over x. so you go down five and over one. since you go down five it's negative. the negative is only added onto the five not the one. and since it's five over one, you don't need to put the over one, it's just automatically there. hope this helps! good luck!

Reflect square JKLM with J(1, 4), K(6, 5), L(7, 0) and M(2, -1) in the y-axis. What are the coordinates of M'?
Given:
Reflect square JKLM with J(1, 4), K(6, 5), L(7, 0) and M(2, -1) in the y-axis.
To find:
The coordinates of M'.
Solution:
We have, M(2, -1) .
If a figure reflected over the y-axis then
[tex](x,y)\to (-x,y)[/tex]
Using this rule, we get
[tex]M(2,-1)\to M'(-2,-1)[/tex]
Therefore, the coordinates of point M' are (-2,-1).

Answer:
$5193.77
Step-by-step explanation:
You want to figure out what x is.
Since x is the number of years after 1996, you can do 2005 - 1996 = 9 years.
Then, plug x = 9 into the equation:
y = 11,000(0.92)^9
Plug this into a calculator and you get: y = $5193.77

Step-by-step explanation:
Jacques wants to make up packs of $0.45 comic books mixed with $0.75 ones to sell at $9.00 per pack. The number of $0.45 comic books is 4 more than the number of $0.75 comic books. Find the number of each type in the pack.
Answer:
The number of each type in the pack is 5 of $0.45 comic books and 9 of $0.75 comic books
Step-by-step explanation:
A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied.
In this case, the unknowns or unknown variables are:
x: number of $ 0.45 comic books
y: number of $ 0.75 comic books
Jacques wants to make up packs of $0.45 comic books mixed with $0.75 ones to sell at $9.00 per pack. Then the equation that represents this situation is:
x*0.45 + y*0.75= 9
On the other side, the number of $0.45 comic books is 4 more than the number of $0.75 comic books. Then the equation that represents this situation is:
x+4=y
The system of equations to solve is:
[tex]\left \{ {{x*0.45+y*0.75=9} \atop {x+4=y}} \right.[/tex]
One way to solve a system of equations is the substitution method, which consists of solving one of the unknowns in one of the equations and substituting its value in the next.
In this case we directly replace the expression of the variable and of the second equation in the first:
x*0.45 + (x+4)*0.75= 9
Solving:
x*0.45 + 0.75*x + 4*0.75= 9
1.2*x + 3=9
1.2*x= 9-3
1.2*x= 6
x= 6÷ 1.2
x=5
Replacing this value in the expression x+4=y you get:
5 +4=y
9=y
The number of each type in the pack is 5 of $0.45 comic books and 9 of $0.75 comic books
Can someone answer this please with an explanation.
Answer:
x=92
Step-by-step explanation:
those to angles are supplementary meaning that they add up to equal 180
so you set up the equation 180=x+x-4
180=2x-4
step 1 add 4 to each side
184=2x
step 2 divide each side by 2
x=92
so the angles equal 92 and 88
Answer:
92°
Step-by-step explanation:
180 degrees on a straight line.
2x - 4 = 180
2x = 184
X = 92°

(PLEASE HELP)Solve the given system using your choice of either graphically or algebraically. Show and explain all work.
y = 2x - 4
x + 2y = 12
Answer:
algebraically.
y = 2x - 4........….....(1)
x + 2y = 12..............(2)
substituting the value of y in equation (2) we get
x+2(2x - 4)=12
x+4x-8=12
5x=12+8
x=20/5=4
substituting the value of x in equation(1) we get
y=2×4-4=8-4=4
:.(x,y)=(4,4)answer
The value of x = 4
The value of y = 4
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first equation be = A
Let the second equation be = B
Now ,
y = 2x -4
Subtracting 2x on both sides , we get
y - 2x = -4 be equation (1)
And ,
x + 2y = 12 be equation (2)
Now , on simplifying the two equations , we get
Multiply equation (1) by 2 , we get
2y - 4x = -8 be equation (3)
Now , subtract equation (3) from equation (2) , we get
5x = 20
Divide by 5 on both sides , we get
x = 4
Therefore , the value of x is 4
Substitute the value of x in equation (2) , we get
4 + 2y = 12
Subtracting 4 on both sides , we get
2y = 8
Divide by 2 on both sides , we get
y = 4
Therefore , the value of y is 4
Hence , The value of x and y is 4

Solve the simultaneous equations
y = 2x^2
y = 3x + 14
Answer:
x = -2
And, x = 7 ÷ 2
Step-by-step explanation:
Given that
y = 2x^2
y = 3x + 14
Now equate these two above equations
2x^2 = 3x + 14
2x^2 - 3x - 14
2x^2 -7x + 4x - 14
x(2x - 7) + 2(2x - 7)
(x + 2) (2x - 7)
So it can be x = -2
And, x = 7 ÷ 2
