Answer:

Option D

Step-by-step explanation:

<em>If the bases are the same in a multiplication problem, then you can simply add the exponents. (i.e., a² × a⁶ = a²⁺⁶ = a⁸)</em>

\bullet \rightarrow 5^4\times5^7

\bullet\rightarrow 5^{4 + 7}

\bullet \rightarrow \boxed{5^{11}}

PLS PLS PLS PLS HELP ASAP!! WILL MARK BRAINLIEST!
grandymaker [24]

Answer:

1. D

2. y = 15.50x + 450

Step-by-step explanation:

1. Since it is a function, the missing pair can't repeat input values with different output, therefore only option D is unique so is the correct choice.

2. x  > (y - 450)/ 15.50

i) Rita gets paid $450 per week.

ii) She gets $15.50 for every new membership she sells.

iii) let y represent the total pay per week.

iv) let x represent the number of new memberships sold.

v) the equation representing total pay is y = 15.50x + 450.

vii) therefore the equation that represents a higher rate of membership sold is given by  x  > (y - 450)/ 15.50

Which of the lines graphed has a slope of -1/2 and a y-intercept of 3?
VARVARA [1.3K]

Answer:

The answer is image 3.

Step-by-step explanation:

The equation for the line will be y = (-1/2)x + 3 so the gradient is negative and you will have to find the x-intercept and y-intercept.

x-intercept :

let \: y = 0

0 =   - \frac{1}{2} x + 3

\frac{1}{2} x = 3

x = 3 \div  \frac{1}{2}

x = 6

y-intercept :

let \: x = 0

y =  -  \frac{1}{2} (0) + 3

y = 3
