Step-by-step explanation:

3x + 2y = -9

(X – Y = -13)×3

3x – 3y = -39

5y = 30

y=6

3x +2(6)=-9

3x=-21

x=-7

Karen bought a $6.95 canvas and 8 tubes of paint. She spent $24.95 on the canvas and the paints. Which equation can be used to find the cost of each tube of paint?

A. 6.95 + 8c = 24.95
B. 8 - 6.95c = 24.95
C. 6.95 - 8c = 24.95
D. 8 + 6.95c = 24.95

Answers

Answer:

A

Step-by-step explanation:

Answer:

A. 6.95 + 8c = 24.95

Step-by-step explanation:

Well, the answer to this question is A is because if we carefully look at this problem, then we can see that Karen bought a canvas for $6.95 and she also bought 8 tubes of paint. Now, the total amount of money that she spent is $24.95.

So, in this problem, our $6.95 is the cost for the canvas that she bought whereas when she mentions buying 8 tubes of paint, she doesn't mention how much each tube of paint costs so, the cost for one tube of paint is unknown and thus, it is a variable.

So, in conclusion, the answer to this question is definitly, A. 6.95 + 8c = 24.95

Write the quadratic equation whose roots are - 5 and -4, and whose leading coefficient is 3.

Answers

Answer:

The quadratic equation is

3x^2+ 27x + 60

Step-by-step explanation:

Here, we have the roots -5 and -4 and the leading coefficient of 3

Mathematically, we simply have this done to the roots;

x = -5 implies x+ 5

x = -4 implies x + 4

The product of this two will be;

(x + 5)(x + 4)

= x^2 + 5x + 4x + 20

= x^2 + 9x + 20

we add the leading coefficient

that would be;

3(x^2 + 9x + 20)

= 3x^2 + 27x + 60

meters above ground at

meters)

Answers

Answer:

See solution below

Step-by-step explanation:

Find the complete question below;

Given the height modeled by the function;

h(t) = 5 + 98t-4.9t²

when t = 0

h(0) = 5 + 98(0)-4.9(0)²

h(0) = 5

when t = 5

h(5) = 5 + 98(5)-4.9(5)²

h(5) = 5 + 490 - 122.5

h(5) = 372.5

when t = 10

h(10) = 5 + 98(10)-4.9(10)²

h(10) = 5 + 980 - 490

h(10) = 495

when t = 15

h(15) = 5 + 98(15)-4.9(15)²

h(15) = 5 + 1470 - 1,102.5

h(15) = 372.5

when t = 20

h(10) = 5 + 98(20)-4.9(20)²

h(10) = 5 + 1960 - 4.9(400)

h(10) = 1965- 1960

h(10) = 5

Adrian is drawing a map to show the directions from his house to his grandmother's house. He uses a scale of 1 1/2
inches represents 12 miles. If the distance from his house to his grandmother's house is 36 miles, how long is the drawing
on the map?

Answers

It’s going to be 4 1/2 inches.
36/12=3
3x1 1/2=4 1/2

The length of the drawing on the map for 36 miles is given by the equation A = 4 1/2 inches

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 equation be represented as A

Now , the value of A is

Let the number of miles be = 12 miles

So , 12 miles on the drawing represents = 1 1/2 inches

Now , the number of miles = 36 miles

12 x 3 = 36 miles

And , 36 miles on the drawing represents = 3 x 12 miles on the drawing

Substituting the values in the equation , we get

36 miles on the drawing represents A = 3 x ( 1 1/2 )

On simplifying the equation , we get

36 miles on the drawing represents A = 4 1/2 inches

Hence , the value on the drawing is 4 1/2 inches
