Answer:

a = 15

Step-by-step explanation:

g(x) is the same thing as "y".  Our point gives us an x and y value, so we will sub those into the equation and solve for a:

-2 = a(1/3) - 7 and

-2 = 1/3a - 7 and

5 = 1/3a so

a = 15

A spinner has five sections, labeled A, B, C, D, and E. The spinner is spun 84 times, and the results are recorded in the table.
Effectus [21]
17% because you would do the number of times it landed on section a (14) over the total times spun (84) which gives you 16.6666 (16 2/3) which would round up to 17%. Hope this helps!

QUADRILATERAL QUAD IS A RECTANGLE FIND THE VALUE OF X AND Y <br><br> DU= 26, QP= 2X +7
grandymaker [24]

Answer:

The value of x is 3.

Step-by-step explanation:

Consider the below figure attached with this question.

Given: Quadrilateral QUAD is a rectangle, DU=26 and QP=2x+7.

We need to find the value of x.

Diagonals of a rectangle are equal.

QA=DU=26             .... (1)

Diagonals bisect each other.

QP=UP=AP=DP=2x+7      .... (2)

Using (1) and (2) we get

DU=QP+AP

DU=QP+QP

DU=2QP

Substitute given values.

26=2(2x+7)

26=4x+14

26-14=4x

12=4x

Divide both sides by 3.

3=x

Hence, the value of x is 3.

2x + 3y = 15 and x - 3y = 3 What's the ordered pair
Ganezh [65]

Answer:

x = 6

y = 1

Step-by-step explanation:

to solve this system of equation we say let

2x + 3y = 15 .......................... equation 1

x - 3y = 3.................................. equation 2

from equation 2

x - 3y = 3.................................. equation 2

x = 3 + 3y.................................... equation3

substitute for x in equation 1

2x + 3y = 15 .......................... equation 1

2(3+3y) + 3y = 15

6 + 6y + 3y = 15

9y = 15 -6 ................................... combining the like terms

9y = 9

divide both sides by the coefficient of y

9y/9 = 9/9

y =1

put y = 1 in equation 3

x = 3 + 3y.................................... equation3

x = 3 + 3(1)

x = 3 +3

x = 6

therefore the value of  x is 6 and y is 1 respectively
