8x+5y=-13, 3x+4y=10 solve by elimination
8x+5y=-13
3x+4y=10
*4 on top
*5 on buttom
32x + 20y = - 52
15x + 20y = 50
subtraction
32x - 15x = - 52 - 50
17x = - 102
x = - 6
and then
3 * (-6) + 4y = 10
4y = 28
y = 7

Mateo completed the following steps to solve the equation -2 + z = 10.
-2 + z = 10
-2 + z − 2 = 10 − 2
z = 8
Explain why Mateo's solution is incorrect. Then show how to correctly solve the equation.
if z = 8
then
-2 + (-8) = - 10
not 10
-2 + z = 10
-2 + 2 + z = 10 + 2
z = 12
check
-2 + (+12) = +10
The explicit formula for a sequence an = 5 – 7n . What is the value of a12?
Answer: its just 12 because a is just a variable
Step-by-step explanation: so like 5 - 7n its just 5 - 7 which in 2 so 12a is just 12
Answer:
-79
Step-by-step explanation:
an=5-7n This is the given equation
Now, we substitute 12 for n and do the equation
a(12)=5-7(12)
a(12)=5-84
a(12)=-79 This is our answer, negative 79

The areas of the two rectangles below are equal. There are two possible areas. One is 105 u2
What is the other one?
Answer:
144 u²
Step-by-step explanation:
⇒ Areas are equal
(6x + 15)(2x + 7) = (4x + 7)(2x + 15)12x² + 42x + 30x + 105 = 8x² + 60x + 14x + 1054x² = 2xx = 1/2Calculating the areas
(6 x 1/2 + 15)(2 x 1/2 + 7) = 18 x 8 = 144(4 x 1/2 + 7)(2 x 1/2 + 15) = 9 x 16 = 144The other one is 144 u²

Consider the trinomial x2 – 9x + 18. Which pair of numbers has a product of ac and a sum of b? What is the factored form of the trinomial?
Answer:
(x-6)*(x-3)
Step-by-step explanation:
a*c
1*18=18
Factors of 18 are:
1, 2, 3, 6, 9, 18
The equation has +18 meaning both signs must be the same; - - or + +
The only two factors that work are -3 and -6
The factored form will be (x-6)*(x-3)

When dividing fractions you follow a rule called Keep change flip or KCF. You keep the first fraction in this case -2/5 then u change the symbol so from ÷ to × and then u flip the fraction. You then solve like you would a multiplication fraction.
Jared wants a quick trip by bus or train to New York. The bus’s average speed is shown in the graph. The train’s average speed is shown in the table. Which form of transportation travels a greater distance per hour?
Train
Time (hours) Distance (miles)
2 90
3 135
6 270
Bus
A graph has time (hours) on the x-axis, and distance (miles) on the y-axis. A line goes through points (0, 0) and (5, 300).
CLEAR CHECK
The train travels 5 miles more per hour than the bus.
The train travels 30 miles more per hour than the bus.
The bus travels 15 miles more per hour than the train.
The bus and train travel the same distance per hour.
Answer:
The bus travels 15 miles more per hour than the train
Step-by-step explanation:
If you look at the graph and how much the train goes per hour, it shows that in a less amount of time than the train the bus gets further. The only answer with the bus traveling further is 15 miles. Therefore, the bus travels 15 miles further per hour than the train!

d = common difference between the terms
Answers
1. I'm assuming you meant to type 0.2, 0.6, 1, 1.4...
In that case, it is increasing by 0.4, so the next three would be:
0.2 + (4-1)(0.4) = 1.8...
=> 1.8, 2.2, 2.6.
2. Here it's reducing by 0.25, so start with:
4 + (5-1)(-0.25) = 3...
=> 3, 2.75, 2.5

What type of triangle has only two congruent sides?.
ABCD is a rectangle AB=2x+4 AD=4x-2 DC=3y BC=y solve for x and y
The values of x and y in the rectangle ABCD are 1 and 2 respectively.
Properties of a rectangleOpposite sides are equal.Opposite sides are parallel.
Therefore,
AB = DC
AD = BC
2x + 4 = 3y
4x - 2 = y
Hence,
2x - 3y = -4
4x - y = 2
multiply equation(i) by 2
4x - 6y = -8
4x - y = 2
-5y = - 10
y = -10 / -5
y = 2
Therefore,
2x - 3(2) = -4
2x - 6 = -4
2x = -4 + 6
2x = 2
x = 1

Ryan works two jobs. He earns $10 per hour working at the hardware store, and he earns $13 per hour working at the shipping
company. If x represents hours at the hardware store and y represents hours at the shipping company, which inequality represents
the situation if Ryan wants to earn a minimum of $300?
A)
10x + 13y s 300
B)
10x + 13y = 300
13x + 10y s 300
D)
13x + 10y = 300
Given :
Ryan works two jobs. He earns $10 per hour working at the hardware store, and he earns $13 per hour working at the shipping.
To Find :
If x represents hours at the hardware store and y represents hours at the shipping company, which inequality represents the situation if Ryan wants to earn a minimum of $300.
Solution :
His total earning is given by :
T = 10( number of hours at hardware store ) + 13( number of hours at the shipping)
T = 10x + 13y
Now, he wants to earn a minimum of $300 i.e T ≥ $300.
So, 10x + 13y ≥ 300
Hence, this is the required solution.
