Answer:
4, A fraction is the numerator divided by the denominator.
Step-by-step explanation:
Fractions do not involve multiplying! It is dividing, so we can rule out all the multiplication related questions.
The top number of a fraction is the numerator 2/3.
The bottom number is the denominator 2/3.
The / is a sign of division.
So, 1 is wrong and 4 is right.

5x+2y = 19
1x + 4y=13
Answer:
{x,y} = {25/9,23/9}
Step-by-step explanation:
// Solve equation [2] for the variable x
[2] x = -4y + 13
// Plug this in for variable x in equation [1]
[1] 5•(-4y+13) + 2y = 19
[1] - 18y = -46
// Solve equation [1] for the variable y
[1] 18y = 46
[1] y = 23/9
// By now we know this much :
x = -4y+13
y = 23/9
// Use the y value to solve for x
what is (2x + 5) + 3 < 22 ?

Answer:
8.1, 41/5, 8.2 repeating, √76
Step-by-step explanation:
Answer:
8.1 < 41/5 < 8.2 < √76
Step-by-step explanation:
41/5 = 8 1/5 = 8.20
_
8.2 = 8.222 ...
√76 ≈ 8.7
8.1 _
8.1 < 8.20 < 8.222 ... < 8.7 = 8.1 < 41/5 < 8.2 < √76

1. What is the radius of the red circle?
2. What is the radius of the blue circle?
3. What are the coordinates for the center of the red circle?
4. What are the coordinates for the center of the blue circle?
5. What is the equation for the red circle?
6. What is the equation for the blue circle?
Answer:
See Below
Step-by-step explanation:
1. Radius of the red circle = 2 units
2. Radius of the blue circle = 1 unit
3. Coordinates for the center of the red circle = (-2, 2)
4. Coordinates for the center of the blue circle = (2, 2)
5. Equation for the red circle:
[tex] \{x - (-2)\}^2 + (y-2)^2 = 2^2 [/tex]
[tex] \red{\boxed {(x+2)^2 + (y-2)^2 = 4}} [/tex]
6. Equation for the blue circle:
[tex] (x-2)^2 + (y-2)^2 = 1^2 [/tex]

The graph shows the distance, y, that a car traveled in x hours:
A graph is shown with the x-axis title as Time in hours. The title on the y-axis is Distance Traveled in miles. The values on the x-axis are from 0 to 5 in increments of 1 for each grid line. The values on the y-axis are from 0 to 375 in increments of 75 for each grid line. A line is shown connecting ordered pairs 1, 75 and 2, 150 and 3, 225 and 4, 300. The title of the graph is Rate of Travel.
What is the rate of change for the relationship represented in the graph? (1 point)
A) fraction 1 over 150
B) fraction 1 over 75
C) 75
D) 150
The speed of the car is 75 mph
===========================================================
Explanation:
The four given points on the diagonal line are:
(1,75)(2,150)(3,225)(4,300)Pick any two points from that list of four. I'll pick the first two points. The coordinates are then plugged into the slope formula below
m = (y2-y1)/(x2-x1)
m = (150-75)/(2-1)
m = 75/1
m = 75 so the answer is choice C
The rate of change of 75 means that each time x goes up by 1, y increases by 75.
For each hour that passes, the car has traveled 75 miles. Therefore, the rate of change is 75 miles per hour.
-----------
Note how,
slope = rise/run = (change in y)/(change in x)change in y = change in distancechange in x = change in timespeed = (change in distance)/(change in time)In short, the slope represents the speed of the car. If the line remains the same slope, then the speed is constant.

it's 75 i took the test

y = x2 + 10x + 10
Answer:
x = -5 - √15 or x = -5 + √15Step-by-step explanation:
[tex]y = x^2+10x+10\\\\y=x^2+10x+25-25+10\\\\y=(x+5)^2-15\\\\y=0\quad\iff\quad (x+5)^2-15=0\\\\(x+5)^2=15\\\\x+5=\pm\sqrt{15}\\\\x=-5-\sqrt{15}\quad or\quad x= -5+\sqrt{15}[/tex]

Pqr is an isosceles triangle and prs is a straight line
Answer:
∠ QRS = 132°
Step-by-step explanation:
Since the triangle is isosceles then the 2 base angles are congruent, that is
∠ PQR = ∠ PRQ = [tex]\frac{180-84}{2}[/tex] = [tex]\frac{96}{2}[/tex] = 48°
∠ PRQ and ∠ QRS are adjacent angles , so
∠ QRS = 180° - 48° = 132°
