Answer:

The answer is x = -7.

Step-by-step explanation:

In order to find this, we need to start by using the slope formula with all of the information that we have.

m(slope) = (y2 - y1)/(x2 - x1)

1 = (3 - -7)/(3 - x)

1 = 10/(3 - x)

Now we can use cross multiplication to solve for x.

1(3 -x) = 1(10)

3 - x = 10

-x = 7

x = -7

If f(x) = 3x2 – 4 and g(x) = 2x - 6, what is g(f(2))?
saveliy_v [14]

Answer:

10

Step-by-step explanation:

find out f(2)

f(2)= (3×2×2) - 4= 8

then g(8) = 16 - 6= 10

This isosceles triangle has two sides of equal length , a, that are longer than the length of the base , b. The perimeter of the
Sholpan [36]
We are give the equation of the perimeter of the triangle as follows:
2a + b = 15.7 
where b represents the base.

Now, if we want to calculate the length of the base, all we have to do is isolate the b in one side of the equation as follows:
b = 15.7 - 2a

We know that a = 6.3 cm, therefore, the length of the base can be calculated as follows:
b = 15.7 - 2(6.3) = 3.1 cm

What is the range of possible sizes for side x? _ < x < _
qwelly [4]

Answer:

2.8 < x < 5.8

Step-by-step explanation:

We must apply the Triangle Inequality Theorem which states that for any triangle with sides a, b, and c:

a + b > c

b + c > a

c + a > b

Here, let's arbitrarily denote a as 4.1, b as 1.3, and c as x. So, let's plug these values into the 3 inequalities listed above:

a + b > c  ⇒  4.1 + 1.3 > x  ⇒  5.8 > x

b + c > a  ⇒  1.3 + x > 4.1  ⇒  x > 2.8

c + a > b  ⇒  x + 4.1 > 1.3  ⇒  x > -2.8

Look at the last two: clearly if x is greater than 2.8 (from the second one), then it will definitely be greater than -2.8 (from the third), so we can just disregard the last inequality.

Thus, the range of possible sizes for x are:

2.8 < x < 5.8

Using the numbers 1 through 9 only once in the boxes, what is the largest value of x you can get?
aliina [53]

Using the numbers 1 through 9 only once in the boxes, the largest value of x you can get is <u>7</u>.

<h3>What are mathematical operations?</h3>

Mathematical operations refer to the calculation of values using operands and mathematical operators.

Mathematical operations are formed like functions to take zero or more input values (operands) to a well-defined output value.

Some of the mathematical operators perform addition, subtraction, multiplication, division, exponentiation, and modulus operations.

<h3>Data and Calculations:</h3>

Mx + y = z

Let m = 1

x = 7

y = 2

1 x 7 + 2 = 9

7 + 2 = 9

9 = 9

Thus, using the numbers 1 through 9 only once in the boxes, the largest value of x you can get is <u>7</u>.
