Help!!!!!!!!!!!!!!!!!!!!!!!

Mathematics
1 answer:
IceJOKER [234]3 years ago
5 0

Answer:

i think b

Step-by-step explanation:

(2,2). When x of the line is 2, y of the line must be 2.

(-2,-2). When x of the line is -2, y of the line must be -2.

(2,2). y=mx+b or 2=1 × 2+b, or solving for b: b=2-(1)(2). b=0.

(-2,-2). y=mx+b or -2=1 × -2+b, or solving for b: b=-2-(1)(-2). b=0.

The equation of the line that passes through the points

(2,2) and (-2,-2)

is

y=1x

b came out to be zero, so there is no "+b" term.

Morgan has $60 to spend on clothes. he wants to buy a pair of jeans for $25 and spend the rest on t shirts each t shirt costs $5
Mashutka [201]

Answer:

C

Step-by-step explanation:

Morgan has $60. That is his spending limit.

He buys a pair of jeans for $25.

Each T-shirt is $5

We don't know how many t-shirts he can buy, so we can represent it with a variable, x

so,

25 + 5x \leq 60\\5x \leq 60 - 25\\5x \leq 35\\x \leq \frac{35}{5} \\x\leq 7

May I please get help with my math lesson if possible I don't know why they are 4 answers if 1 of the answers don't apply to any
Doss [256]

Answer: S1:E7 ; S2:E1 ; S3:E5

Step-by-step explanation:

What we know:

  • 3 answers apply
  • We need to find which answers go with each question

**A lot of info is problem-specific.

How to solve:

Since we only need to write the equations, we simply need to find the x and y variables, and the total.

Process:

Problem 1:

  • Find the x                                                                     5.50
  • Find the y                                                                     3
  • Find the total                                                                145
  • Write equation                                                      5.50 + 3 = 145

Problem 2:

  • Find the x                                                                     2.50
  • Find the y                                                                     0.75
  • Find the total                                                                25
  • Write equation                                                      2.50 + 0.75 = 25

Problem 3:

  • Find the x                                                                     2
  • Find the y                                                                     5
  • Find the total                                                                50
  • Write equation                                                        2 + 5 = 50

Solution: S1:E7 ; S2:E1 ; S3:E5

Just substitute the value to the x, Like this.

F(x)=x²+2x-7

F(1)=(1)²+2(1)-7
