How to do these problems

Answers

Answer 1

Answer: so all you have to do is divide the fractions. you would write 7/15 in your calculator, and boom you have the answer. or, you can just divide it by pencil and paper, which is harder. 4/5=0.8

What is the effect on the graph of the linear parent function, f(x) = x, when f(x) is replaced by f(x + 5)?A) The graph of the line becomes steeper.
B) The graph of the line shifts horizontally right 5 units.
C) The graph of the line shifts vertically down 5 units.
D) The graph of the line shifts horizontally left 5 units.

Answers

Answer:

D) The graph of the line shifts horizontally left 5 units.

Adding a number, n, inside of the parenthesis with x would move the parent function n units to the left.

Here are the rules:
F(x + a) shifts a units left.
F(x - a) shifts a units right.

You can see this by taking for example f(x) = x^2 then f(x+5) = (x+5)^2, if you graph y=x^2 and y=(x+5)^2, you will see it is shifted 5 units to the right.

A geometry student says; "I got lost in that lesson - I wrote down that AD/AB = AC/AB but I have no ideawhere it comes from."
Which of the following should have been the proportion that the student wrote?
answer choices:
a) AD/AB=AB/AC
b) AD/AC=AB/AB
c) AB/AD=AB/AC
d) AB/AC=AB/AD

Answers

Answer:

Therefore the choice is

a) AD/AB=AB/AC

Step-by-step explanation:

In Δ ADB and Δ ABC

∠A ≅ ∠A …………..{Reflexive Property}

∠ ADB ≅ ∠ ABC ..............{ measure of each angle is 90° given }

Δ ADB ~ Δ ABC ….{Angle-Angle Similarity test}

If two triangles are similar then their sides are in proportion.

$(AD)/(AB) =(AB)/(AC)\ \textrm{corresponding sides of similar triangles are in proportion}\n$

Therefore the choice is

a) AD/AB=AB/AC

Answers

$72-x+20=70 \n \n 92-x=70 \n \n -x=-22 \n \n x=22 \n \n blank=22$

$72-x+20=70 \n -x+92=70 \n -x+92-92=70-92$

Divide both sides by -1

$(-x)/(-1) = (-22)/(-1) =22$
