Y = -5x + 3 y = 8x – 23

Mathematics
1 answer:
svet-max [94.6K]4 years ago
4 0

Answer:

x = 2 , y = -7.

Step-by-step explanation:

Two Equations are given in the question ,

y = -5x + 3 -(1)

y = 8x - 23  -(2)

We have to solve both of them ,

Subtracting equation 2 from equation 1 , we will get

-5x -8x + 3 + 23 = 0

-13x + 26 = 0.

So,

x = 2.

Putting x = 2 in Equation 1 ,

y = -10 + 3.

y = -7.

Thus Solution of both of the equations is x = 2 , y = -7.

Tammy learns in science class that water freezes when its temperature is
Oksanka [162]

The required number line that shows all of the possible

temperatures is option A.

<h3>Inequalities and number line</h3>

From the given question, we have that water freezes when its temperature is no more than 32 °F

The statement no more than 32 °F shows that the temperature cannot be greater than 32 but less than or equal to 32. This is written mathematically as;

t ≤ 32.

We are to select the number line that shows all of the possible temperatures. The required number line that shows all of the possible

temperatures is option A.

Classify the triangle with 9, 15, 19 as an acute right obtuse or not a triangle
Novosadov [1.4K]

Answer:

Hence the correct option is the last one . The triangle is an obtuse angled triangle.

Step-by-step explanation:

i) the sum of any two sides added together is greater than the third side hence this is a triangle.

ii) it is<em><u> not</u></em> a right angled triangle as \sqrt{9^{2} + 15^{2} } \neq  19 and \sqrt{9^{2} + 15^{2} } <  19

iii) the triangle is not acute from ii) above

iv) the triangle is an obtuse triangle from ii) above.
