Hello There!

Write it in numerical form:
9.42
One decimal place means there is one digit after the decimal point
You would round down because the number in the hundredths column is 4 or below.
Therefore, your answer would be 9.4

Hope This Helps You!
Good Luck :)

Identify the x- and y-intercepts of f(x) and the x- and y-intercepts of g(x). f(x) =3x−1;g(x)=2f(x)−4

Tju [1.3M]

F(x)=3x-1

y-intercept:
y=3(0)-1
y=-1

x-intercept:
0=3x-1
1=3x
1/3=x

g(x)=2f(x)-4

y-intercept:
y=2f(0)-4
y=2(-1)-4
y=-6

x-intercept:
0=2f(x)-4
0=2(3x-1)-4
0=6x-2-4
0=6x-6
0=x-1
1=x

Tim has an after-school delivery service that he provides for several small retailers in town. He uses his bicycle and charges $

nlexa [21]

Answer:

$4.84

Step-by-step explanation:

Given that

For delivery within $1\frac{1}2$ mi, charges = $1.25

For delivery within $1\frac{1}2$ mi - $1\frac{3}4$ mi, charges = $1.70

For delivery within $1\frac{3}4$ mi - 2 mi, charges = $2.15

and

so on.

i.e.

For delivery within 2 mi - 2 $\frac{1}4$ mi, charges = $2.60

For delivery within 2 $\frac{1}4$ mi - 2 $\frac{1}2$ mi, charges = $3.05

For delivery within 2 $\frac{1}2$ mi - 2 $\frac{3}4$ mi, charges = $3.50

For delivery within 2 $\frac{3}4$ mi - 3 mi, charges = $3.95

For delivery within 3 mi - 3 $\frac{1}4$ mi, charges = $4.40

So, every 0.25 mi or $\frac{1}4$ mi increase in distance, there is an increase of $0.45 in the charges.

It is given that there is increase of 10% in the rates.

i.e. for every 0.25 mi increase in distance, there is an increase of 0.45*1.10 = $0.495 in the charges.

The distance of $3\frac{1}8$ miles lies within the range 3 mi - 3 $\frac{1}4$ mi.

So actual charges after increase of 10%

$\Rightarrow \$4.40 \times \dfrac{110}{100}\\\Rightarrow \$4.40 \times 1.10\\\Rightarrow \bold{\$4.84}$

Describe and correct the error in solving the proportion?

Ilia_Sergeevich [38]

Answer: Choice B

They did not perform the cross multiplication properly

The correct step should be m*24 = 8*15 which solves to m = 5

========================================================

Explanation:

In general, if we had the equation A/B = C/D, then it cross multiplies to A*D = B*C. We refer to this as cross multiplication because of the shape made when we connect the terms (to figure out what multiplies with what). The diagram below shows what I mean.

So that's why m/8 = 15/24 cross multiplies to m*24 = 8*15

Simplifying things a bit leads to 24m = 120. Then we divide both sides by 24 to fully isolate m and we get m = 120/24 = 5. Therefore, m = 5.

Hello can you please help me posted picture of question

ollegr [7]

The correct option is (B) 4x^2 + 18x + 18

Explanation:
The area is given as:
(3+2x)(6+2x)

To find the polynomial just simplify it.
3(6+2x) + 2x(6+2x)

18 + 6x + 12x + 4x^2

4x^2 + 18x + 18
