x=-3y+3

x-3y=-15

Answers

Answer 1

Answer:

x = -6

y = 3

Step-by-step explanation:

Since we are given what x equals, we will plug that in first to the second equation.

(-3y+3) - 3y = -15

Solve by combining like-terms and isolating y.

-6y + 3 = -15

-6y = -18

y = 3

Now plug in y to the first equation to solve for x.

x = -3(3) + 3

x = -9 + 3

x = -6

The number factor of a variable term is called the
a) variable
b) constant
c) algebraic expression
d) numerical coefficient

Answers

It’s the coefficient. I don’t know what a numerical coefficient is but that would be my best guess. Sorry if it is wrong. Hope that helps!

The number factor of a variable term is called the numerical coefficient.

Algebraic expression are made of terms . Terms might be a signed numbers, a variable, or a constant multiplied by a variable or variables.

Examples of an algebraic expression is as follows:

4x + 7

When a constant is multiplied by a variable or variables , that constant is called the coefficient.

In our example the variable is x . The number factor of the variable term x is called the numerical coefficient .

Therefore, the numerical coefficient in our case is 4.

Which value of m makes this equation true? m - 8 = -1
m = 9
m=7
m= -9
m = -7

Answers

Answer:

The answer is 7 because if we write 7 - 8 = -1, then we could see that the answer would be -1 since 7 is 1 value lower than 8, and 8 - 8 = 0, so if 7 is lower than 8 by 1, then you would go one value lower from 0, which is -1. You can also figure this out by looking at a number line and starting from 7 and then going backwards 8 times and whatever number you land on after going back 8 times is your answer.

plssssss help fast!!!!Launching From a Tower
Suppose a projectile is launched from a tower into the air with an initial velocity of 48 feet per
second. Its height, h, in feet, above the ground is modeled by the function
h = -16t2 + vot + 64
where t is the time, in second, since the projectile was launched and v, is the initial velocity.
A. What tower platform height was the projectile launched from?
B. How long was the projectile in the air?
C. When did it reach its maximum height?
D. What was its maximum height?
E. What domain makes sense for the function in this context?

Answers

Answer:

A. h = 64

B.  t = 4 -> 4 seconds

C. t = 1.5 -> 1.5 seconds

D. maximum height is 100 ft

E. The domain that makes sense for the function in this context is t

is any positive real number since time can not be negative.

Step-by-step explanation:

h = -16t2 + vt + 64

A. What tower platform height was the projectile launched from?

when the projectile was not launched, t = 0

h = -16(0)^2 + v(0) + 64 = 64

B. How long was the projectile in the air?

if the projectile lands, its height = 0 so substitute 0 for h

0 = -16(t)^2 + 48(t) + 64

  = -16(t^2 - 3t -  4)

 = -16(t - 4)(t + 1)

t = 4 or t = -1

Since time can not be negative, t = -1 can not be the answer. Therefore, the projectile lands when t = 4 or 4 seconds.

C. When did it reach its maximum height?

maximum -> t=-b/2a where in -16(t)^2 + 48(t) + 64, b = 48 and a = -16

t = -48/-32 = 1.5

D. What was its maximum height?

plug t = 1.5 into -16(t)^2 + 48(t) + 64

-16(1.5)^2 + 48(1.5) + 64 = -36 + 72 + 64 = 100

E. The domain that makes sense for the function in this context is t

is any positive real number since time can not be negative.

The maximum height is 100 feet at a time of about 1.5 seconds.

What is an equation?

An equation is an expression that shows the relationship between two or more variables and numbers.

Given that:

h = -16t² + vt + 64

-16t² + 48t + 64 = h

h is the height, v is the initial velocity and t is the time.

a) The tower height is about 64 feet from the equation

b) The time is at h = 0, hence:

-16t² + 48t + 64 = 0

t = 4 seconds

c) Maximum height is at h' = 0

h' = -32t + 48

-32t + 48 = 0

t = 1.5 seconds

d) h(1.5) = -16(1.5)² + 48(1.5) + 64 = 100 feet

a remote control car races straight down the street at 26 miles per hour. Two hours later, a second remote control car races straight down the same street at 52 miles per hour in pursuit of the first car. From the moment the first care started, how many hours will it take thje second car to catch up to the first? What type of problem best exemplifies this question?

Answers

Answer:

4 hours

Step-by-step explanation:

Given

Speed of the first car = 26 mphSpeed of the second car = 52 mphTime difference  = 2 hoursThe first car makes 2*26 = 52 miles before the second car starts racing

Let the time the second car races before catching the first car be x

The equation:

26x + 52 = 52x52x - 26x = 5226x = 52x = 2

It takes 2 hours for the second car to catch the first car.

It takes 2 + 2 = 4 hours from the moment the first car started the race.
