Show all work to solve 2x2 +7x - 4 = 0
Heyy!!
2x2 + 7x - 4 = 0
4x + 7x - 4 = 0
11x - 4 = 0
11x = 4
x = 4/11
ANSWER: x = 4/11x+3y=-5
4. Tyler and Han are trying to solve this system by substitution:
Tyler's first step is to isolate x in the first equation to get x = -5 - 3y. Han's first step
is to isolate 3y in the first equation to get 3y = -5 - X.
Show that both first steps can be used to solve the system and will yield the same
solution.
Answer:
Tyler's - (-5 - 3y) + (3y) = -5
Han's - (x) + (-5 - x) = -5
Step-by-step explanation:
If we are going to use Tyler's first step then we would use x = - 5 - 3y and substitute it in the original simultaneous equation x + 3y = -5, becoming (-5 - 3y) + (3y) = - 5 giving an exact answer of - 5.
But if we are using Han's first step then we will still substitute into the original simultaneous equation but in 3y. It would become
x + (-5 - x) = - 5 which also gives us an exact answer of -5.
Thus proving that both first steps show the same solution of -5.

W/5+20=22. How do I do this
Answer:
W = 10
Step-by-step explanation:
W / 5 + 20 = 22
W / 5 - 20 = 22 - 20
W / 5 = 2
W * 5 = 2 * 5
W = 10
Step-by-step explanation:
[tex] \frac{w}{5} + 20 = 22 \\ \\ \frac{w}{5 } = 22 - 20 \\ \\ \frac{w}{5} = 2 \\ \\ w = 5 \times 2 \\ \\ w = 10[/tex]

Which graph represents a linear function? (4 points)
A coordinate plane is shown with a curved line that starts in the bottom left area of the graph, passing through the point -1 comma -5, curving to pass through the y-axis at 2.5, then curving up again to pass through the point 1 comma 5
A coordinate plane is shown with a line passing through the x-axis at negative 2 and the y-axis at negative 6.
A coordinate plane is shown with a parabola graphed in an upward U shape. The bottom of the parabola touches the y-axis at -10 and curves upward on both sides
A coordinate plane is shown with a wavy line that sits on the x-axis and moves across the graph in even up and down waves.
Answer:
The second option
Step-by-step explanation:
Linear means a straight line.
Choices 1, 2, and 4 are wrong because they are either a parabola or wavy, and by definition of both of these terms, they are not straight and are therefore not linear.
A taxi ride costs $3 plus $2.50 per mile. if sasha has 37 in cash,what is the greatest whole number of miles she can ride in this taxi? 25 points if done with explanation and correct answer
Answer:
13 miles is the greatest whole number of miles she can go.
Step-by-step explanation:
37-3=34
$5 for 2 miles
34/5 = 6 remainder 4
that is 12 miles. But since she still has 4 dollars left, she can go another mile. so, 12 +1 = 13

Answer:
Value of x = 3
m∠HEB=27°
Step-by-step explanation:
1) CEH and HEB are complementary angles, therefore both of their angles added together will be 90 degrees
2) Set the two equations added together equal to 90 and solve for x
19x+6+9x=90
28x=84
x=3
3) Plug in x into 9x to get HEB
9(3)=27

y = x + 3
Answer:
x=33 and y=36
Step-by-step explanation:
You can rewrite the equation into
x+2=4/3x-9
Now you can subtract 2 on both sides
x=4/3x-11
Now subtract 4/3x on both sides:
-1/3x=-11
Multiply -3 on both sides:
x=33
Now substitute x with 33
y=33+3
y=36
Thus x=33 and y=36
Hope this helps!
The equation of a line is given below.
2x + 5y = -5
Find the slope and the y-intercept.
Then use them to graph the line.
Answer:
y=-2/5x-1
Step-by-step explanation:
2x+5y=-5
Step 1: Add-2x to both sides.
2x+5y=-5
+-2 +-2
5y=-2x-5
Step 2: Divide both sides by 5.
5y ÷ 5 = -2x-5÷5
y=-2/5x-1
The front lawn of NPHS has a roped off area of 2x^2 - 11x + 15. What are the
possible dimensions of the roped off area?
Answer:
[tex]x-3[/tex] by [tex]2x-5[/tex] units
Step-by-step explanation:
Use the slide-and-divide method to factor the polynomial:
[tex]2x^2-11x+15[/tex]
[tex]x^2-11x+30[/tex]
[tex](x-6)(x-5)[/tex]
[tex](x-3)(2x-5)[/tex]
Therefore, the dimensions are [tex]x-3[/tex] by [tex]2x-5[/tex] units
