Solve each system by using substitution.
3x - y = 4

Answer:
[tex]from \: last \: equation : \\ x = - 4 - 5y - - - (a) \\ substitute \: in \: first \: equation \\ 3( - 4 - 5y) - y = 4 \\ - 12 - 15y - y = 4 \\ - 16y = 16 \\ y = - 1 \\ \\ therefore \: from \: (a) \\ x = - 4 - 5( - 1) \\ x = 1[/tex]
Point M is the midpoint of AB.
If AM = 12x + 8 and MB = 10x + 15, then AM = ?
Answer:
AM = 50
Step-by-step explanation:
12x + 8 = 10x + 15
subtract 10x from both sides
2x + 8 = 15
subtract 8 from both sides
2x = 7
divide both sides by 2
x = 3.5
-----------------------------
AM = 12x + 8
AM = 12(3.5) + 8
AM = 42 + 8
AM = 50
Deshawn and Chris are playing soccer. Chris takes a shot on goal from 25 feet away. Deshawn can reach the top of the 8-ft goal when standing. The function that models the height of the ball across the field is ()=−.(−)+f of , open x close , equals negative , 0.05 . Open x minus 16 close squared . Plus 11.
Answer:
Yes, Chris will score
Step-by-step explanation:
Given the function :
F(x) = - 0.05(x - 16)² + 11
Distance from goal = 25
Height of goal = 8
Scoring condition, if ball isn't blocked :
If the ball travels a distance of 25 feets towards goal and elevation of ball isn't greater than 8 feets, then Chris will score ;
Function which models ball height with respect to distance, x
Put x = 25 in the equation and se if f(x) < 8 feets
F(25) = - 0.05(25 - 16)² + 11
F(25) = - 0.05(9)² + 11
F(25) = - 0.05 * 81 + 11
F(25) = - 4.05 + 11
F(25) = 6.95 feets
Hence, Chris would score if ball isn't vlaocjed by DeShawn because the height of ball is lower than the height of the goal.

Step-by-step explanation:
Jamal's friends toss 12 balls to him at the same time. Three balls are red, 3 are green, 3 are blue, and 3 are white. Jamal manages to catch 5 of the balls.
What is the probability that he catches 2 red balls and 1 ball of each of the other colors?
Answer:
81/792 or 9/88 or 10.2%
Step-by-step explanation:
Possibility: nCr(12,5) = 792
Red: nCr(3,2) = 3
Blue, Green, White: nCr(3,1) = 3
3 * 3 * 3 * 3 = 81
81/792 simplified is 9/88 percentage is 10.22%
The probability that Jamal will catch 2 red balls and 1 ball of each of the other colors is 0.1025.
What is probability?Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.
The probability of any event always lies in the close interval of 0 and 1 [0,1].
The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.
The total numbers of balls are 12.
Each color has 3 balls.
If total 12 balls are tossed, the number of ways of catching 5 of them is,
¹²C₅ = 792
The number of ways of catching 2 red balls out of 3 is ³C₂ = 3
The number of ways of catching 1 green ball out of 3 is ³C₁ = 3
The number of ways of catching 1 blue ball out of 3 is ³C₁ = 3
The number of ways of catching 1 white ball out of 3 is ³C₁ = 3
Thus, the probability as per the question is given as follows,
(3 × 3 × 3 × 3)/792
= 81/792
= 0.1025
Hence, the probability of catching 2 red balls and 1 ball of each of the other colors is 0.1025.

What which is equivalent to√x10?
Answer:
E) x^5
Step-by-step explanation:

Joseph runs 2 miles on Monday. Each day after that, he runs the same 1 1/3 mile route every
morning. His goal is to run at least 6 miles by the end of the week.
Which inequality represents the least number of days after Monday that Joseph needs to run
to reach his goal? *
Answer:
2 + 1 1/3x ≥ 6
x ≥ 3 days
Step-by-step explanation:
Monday = 2 miles
Other days = 1 1/3 miles
x = least number of days after Monday that Joseph needs to run
to reach his goal
Total miles = 6 miles
The inequality is
2 + 1 1/3x ≥ 6
1 1/3x ≥ 6 - 2
1 1/3x ≥ 4
4/3x ≥ 4
Divide both sides by 4/3
4/3x ÷ 4/3 ≥ 4 ÷ 4/3
x ≥ 4 × 3/4
x ≥ 3 days

OB. 107%
C. 85%
D. 22%
Answer:
107%
Step-by-step explanation:
because if we look at the x-axis, Discount (%)
and look at 35 which is between 30 and 40
and start going up we get near 100
so
107%
or?
we use the two points and with that we find the slope first
[tex]\frac{y2-y1}{x2-x1}[/tex]
plug in (20,62) and (10,32)
[tex]\frac{32-62}{10-20}[/tex]
equals
[tex]\frac{-30}{-10}[/tex]
simplify to 3
then we use
y - y1 = m (x - x1)
y - 62 = 3 (x - 20)
y - 62 = 3x - 60
add 60 from both sides
y - 2 = 3x
add 2 to both sides
y=3x+2
then plug in 35
y= 3(35) + 2
which is
107

Find the measure of x and y (3x-3) (4y+4) 60 degrees
Answer:
y=29
X=21
Step-by-step explanation:
180-60=120
4y+4=120 get y by itself and remember that what ever you do to one side you do to the other.
Alternate interior angles are congruent so 3x-3=60
Hence, the values of [tex]y=29,x=21[/tex].
What is a degree?
A degree, usually denoted by °, is a measurement of a plane angle in which one full rotation is [tex]360[/tex] degrees.
Here given that,
The measure of [tex]x[/tex] and [tex]y[/tex] is
[tex](3x-3) (4y+4)[/tex] and the angle is [tex]60[/tex] degrees.
As we know the sum of three angles is [tex]180[/tex] a degree.
[tex]180-60=120[/tex] degree
Since [tex]4y+4=120[/tex] get [tex]y[/tex] we are doing it on the one side so we need to do it on the other side also.
And the alternate angles are congruent [tex]3x-3=60[/tex] degrees.
Hence, the values of [tex]y=29,x=21[/tex].

Peter bought 6 mangos at $x each. He also bought a papaya for $5. If x =2, find the total cost of the fruits.
Answer:
Total cost of all fruits = $17
Step-by-step explanation:
Given:
Number of mangoes Peter bought = 6
Cost of each mango = x
Cost of papaya = $5
Find:
Total cost of all fruits if x = 2
Computation:
If x = 2
So,
Cost of each mango = x
Cost of each mango = $2
Cost of 6 mangoes = 6 × Cost of each mango
Cost of 6 mangoes = 6 × 2
Cost of 6 mangoes = $12
Total cost of all fruits = Cost of 6 mangoes + Cost of papaya
Total cost of all fruits = 12 + 5
Total cost of all fruits = $17
