"Where are you two going at this time of day? Playing hooky, I suppose. I'll just call up the principal and tell him!"

Eric was rock climbing. At one point, he stopped and climbed straight down 2\dfrac{1}{2}2

nikitadnepr [17]

The equation that matches the given situation is $-2\frac{1}{2}+6\frac{3}{4}=?$ . So, after two moves, Eric's elevation changed $4\frac{1}{4}$ meters above.

We know that in mathematics, subtraction means removing something from a group or a number of things. What is left in the group gets smaller when we subtract. The minuend is the first element we use. The subtrahend is the part that is being removed. The difference is the portion that remains after subtraction.

Assume that "negative" means climbing down and "positive" means climbing up. We must locate the elevation change in this area.

Given that Eric climbed straight down $2\frac{1}{2}$ meters. So we can write $-2\frac{1}{2}$ .

Again Eric climbed straight up $6\frac{3}{4}$ meters. So, we can write $6\frac{3}{4}$ .

Then the change = $-2\frac{1}{2}+6\frac{3}{4}$

= $-\frac{(2*2+1)}{2}+\frac{6*4+3}{4}$

= $-\frac{5}{2} +\frac{27}{4}$

= $\frac{-(5*2)+27}{4}$

= $\frac{-10+27}{4}$

= $\frac{17}{4}$

= $\frac{4*4+1}{4}$

= $4\frac{1}{4}$

Therefore, the equation that matches the given situation is $-2\frac{1}{2}+6\frac{3}{4}=?$ . So, after two moves, Eric's elevation changed $4\frac{1}{4}$ meters above.

Answer:

B. 95º

Step-by-step explanation:

Supplementary angles are ones that add up to 180º.

So if angle 1 is 85º, then the equation would be:

(x-the measure of angle 2)

X + 85 = 180

Solve for x:

X + (85-85) = 180-85

X = 95.

Hope this helps! Have a great day!

Find the value of x. Please help. I am confused

Oxana [17]

Answer:

x=30

Step-by-step explanation:

Exterior Angle Theorem = the exterior angle of a triangle is equal to the sum of the two opposite interior angle

Thus, 2x+6+36=4x-18

2x+42=4x-18 add 18 to both side

2x+60=4x minus 2x

60=2x

x=30

What is the transformation of the logarithmic function from the parent log5 x?

TiliK225 [7]

Answer: Choice #3 - compressed horizontally and translated by 4 units to the right.

$g(x)=\log_5(4x-16)=\log_5 4(x-4)$

This corresponds to horizontal shift to the right by 4 units and a horizontal compression.

Which equation demonstrates the multiplicative identity property

nignag [31]

<em>Equation b) (-3 + 5i) (1) = -3 + 5i demonstrates the multiplicative identity property </em>

<h3>Further explanation</h3>

There are several properties in integer multiplication operations

1. closed property

Multiplication between integers will produce integers too

2. commutative property

a x b = b x a

3. associative property

ax (bxc) = (axb) xc

4. identity

ax1 = 1 x a = a

5. distributive property

* addition

ax (b + c) = axb + axc

* substraction

ax (b-c) = axb - axc

The Multiplicative Identity is <u><em>1 </em></u>

<u><em>The multiplicative identity property states that any number multiplied by 1 will produce an original number. </em></u>

We complete the answer choices available from the problem above:

a) (- 3 + 5i) + 0 = -3 + 5i

O is an identity in the sum operation, the statement is false

b) (-3 + 5i) (1) = -3 + 5i

1 is a Multiplicative Identity of multiplication, so the statement is true

c) (-3 + 5i) (-3 + 5i) = -16-30i

d) (-3 + 5i) (-3 + 5i) = 16 + 30i

choice c and is a multiplication factor, so the statement is false
