Answer:

x = -11.5;. y = -58.5

Step-by-step explanation:

-3x+y=-24

y=7x+22

-3x+(7x+22)=-24

-3x+7x+22=-24

4x=-24-22

4x = -46

x = - 11.5

y= 7 * (-11.5) + 22

y = -58.5

Answer:

first one: 8

second one: 3

Step-by-step explanation:

-3x + y = -24 |÷(-3x)

y = 8

y = 7x + 22 |-y

(y would be 1; the 7x moves to the other side.) meams:

7x = 21 |÷7

x = 3

alexandrea and imani each think of a number. alexandras number is 8 more than Imanis number. the sum of two numbers is 50. what

juin [17]

Alexandera=a
imani=i

a is 8 more than i or
a=8+i

the sum of the 2 numbers is 50 or
a+i=50

a=8+i
so subsitute 8+i for a in a+i=50
8+i+i=50
8+2i=50
subtract 8 from both sides
2i=42
divide both sides by 2
i=21

subsiutte into a=8+i

a=8+21
a=29

a=29
i=21

Which of the following represents the factorization of the trinomal below

Allisa [31]

I believe B. is your answer. If you use the ac method, you will multiply 8 and 3 which is 24. So now, what factors of 24 will give you 10?6 and 4

Now substitute

$8 {x}^{2} + 4x + 6x + 3$
Now do factorization by grouping.

$4x(2x + 1) + 3(2x + 1)$
Therefore, your answer is (4x+3)2x+1)
