Taft CLB Algebra 2 Unit 1: Systems of Linear Equations and Inequalities 2020-2021 / 3 of 13

Tju [1.3M]

Answer:

$B + G \leq 15$

$6B + 10G \geq 90$

Step-by-step explanation:

Given

Represent Babysitting with B

Represent Gas Station with G

Total workhours = At most 15

Earnings = At least $90

First, we need to represent the work hours as inequality

B + G = At most 15

At most 15 means less than or equal to 15.

So, we have:

$B + G \leq 15$

Next, we represent the earnings as inequality.

6 hours of babysitting is: 6B

10 hours at gas station is: 10G

So:

6B + 10G is at least 90

At least 90 means greater than or equal to 90

So, we have:

$6B + 10G \geq 90$

Tony’s Electronics is marking down the price of a TV 23% from the original price of $175. Which expression can be used to find t

Arlecino [84]

Answer:

The sale price is $\$134.75$

The expression is $\$175(0.77)$

Step-by-step explanation:

we know that

The sale price is equal to subtract the discount price from the original price

The discount price is equal to multiply the original price by the percent discount in decimal form

Let

x ----> the sale price

y ---> discount price

$23\%=23/100=0.23$ ----> percent discount in decimal form

$y=\$175(0.23)=\$40.25$

$x=\$175-y$

substitute

$x=\$175-\$40.25=\$134.75$

therefore

the expression is

$175-0.23(175)\\175(1-0.23)\\175(0.77)$

A quadratic function y=f(x) is plotted on a graph and the vertex of the parabola is (3,6). What is the vertex of the function de

maks197457 [2]

Answer:

vertex = (- 2, 6)

Step-by-step explanation:

Given f(x) then f(x + a) represents a horizontal translation of f(x)

• If a > 0 then a shift to the left of a units

• If a < 0 then a shift to the right of a units

Here a = 5 , thus a horizontal translation left by 5 units.

Thus

vertex of g(x) = (3 - 5, 6 ) = (- 2, 6 )

N circle C, r = 32 units. What is the area of circle C?

charle [14.2K]

The answer is: " 1024π units² " ; or; " 3215.36 units² " .
______________________________________________________
A = π * r² ;

A = π * 32² = 1024 π units² ;

or, using "3.14" for "π" ;

1024 * π = 1024 * (3.14) = 3215.36 units² .
