How many solutions does the system of equations x − y = 7 and y equals the square root of the quantity 3 times x plus 3 end quantity minus 2 have?
9514 1404 393
Answer:
one solution (11, 4)
Step-by-step explanation:
Both equations describe curves with positive slope. The y-intercept of the line (-7) is less than that of the root function (-2), so the line must intersect the root function in exactly one place. There is one solution.
__
Solved in the conventional way, the equation would become a quadratic, with two solutions. One of them is extraneous. (That is why I prefer a graphical solution.)
Given ...
x -y = 7
y = √(3x +3) -2
We can substitute for y to get ...
x -7 = √(3x +3) -2
x -5 = √(3x +3)
x^2 -10x +25 = 3x +3 . . . . . . square both sides
x^2 -13x +22 = 0 = (x -11)(x -2) . . . . . gives solutions x=11, x=2
The value x=2 does not satisfy the equation ...
x -7 = √(3x +3) -2 ⇒ 2 -7 = √(3·2 +3) -2 ⇒ -5 = 1 (false)
Determine the intercepts of the line.
Do not round your answers.
y - 3 = 5(x - 2)
Please help!!!
Answer:
the Y intercept is (0,-7) and the X intercept is (7/5,0)
Step-by-step explanation:
For Khan academy
The y-intercept is -7 and the x-intercept is 7/5 if the equation of the line is y - 3 = 5(x - 2)
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have an equation of the straight line:
y - 3 = 5(x - 2)
For y-intercept:
Plug x = 0
y - 3 = 5(0 - 2)
y = -7
For x-intercept:
Plug y = 0
0 - 3 = 5(x - 2)
x = 7/5
Thus, the y-intercept is -7 and the x-intercept is 7/5 if the equation of the line is y - 3 = 5(x - 2)

Ramon’s had a 60 question test and got 70% of the questions correct how much did he get incorrect?
Answer:
18
Step-by-step explanation:
total no. of questions - 60
percentage of correct answers - 70%
60 = 100%
? = 70%
cross multiply and divide the answer by hundred
[tex] \frac{60 \times 70}{100} \\ \\ \frac{4200}{100} = 42[/tex]
answers got correct = 42
therefore answers got incorrect = 60 - 42 = 18
answer = 18

Given below are expressions in factored form in which both factors are binomials. Follow the process in multiplying the binomials using FOIL method and answer the questions that follow. Write your answer on your answer sheet.
1. (x + 1)(x + 2) = x2 + 2x + x + 2
= x2 + 3x + 2
2. (x-2)(x-3) =x2 – 3x - 2x + 6
= x2 - 5x + 6
3. (x + 3)(x-4) = x2 - 4x + 3x - 12
= x² - x - 12

I believe your answer is:
[tex]m = -\frac{2}{5}[/tex]
»»————- ★ ————-««
Here’s why:
⸻⸻⸻⸻
[tex]\text{We will convert the equation to slope intercept form.}\\\\2x + 5y = 10\\\rule{150}{0.5}\\\rightarrow 2x + 5y = 10\\\\\rightarrow 2x - 2x + 5y = 10-2x\\\\\rightarrow 5y = 10-2x\\\\\rightarrow 5y = -2x + 10\\\\\rightarrow\frac{5y=-2x+10}{5}\\\\\rightarrow\boxed{y = -\frac{2}{5}x+2}[/tex]
⸻⸻⸻⸻
Since [tex]-\frac{2}{5}[/tex] replaces 'm's spot, it is the slope of the given equation.

plz help. DUE IN 10 MINUTESYou have a recipe that calls for 5 parts (cups) of water for every 3 parts (cups) of flour. you use 15 cups of water. How much flour do you need?
Answer:
9
Step-by-step explanation:
if you have 5 for every 3 to get from 5 to 15 you multiply by 3 so now just multiply 3 by 3 to get 9
Answer:
9 cups of flour
Step-by-step explanation:
since there's 15 cups of water and you need 3 cups of flour for every 5 cups of water 15 divided by 5 is 3 and 3 times 3 is 9 so there should be 9 cups of flour
