4 1/2 + 1 3/5
What is the sum because I’m very slow
First, chance the fractions so the denominators are the same. The GCF of these is 10, so multiple both numerators and denominators so the denominator is 10.
1/2 = 5/10
3/5 = 6/10
Add the wholes and the fractions:
5 11/10
Since the numerator is higher than the denominator, we can make another whole:
11/10 - 10/10 = 1/10
So 5 becomes 6 because of the whole:
5 + 1 = 6
The fraction becomes 1/10:
So the final answer is:
6 1/10
(Important Note: Unless asked, you must always put fractions into its smallest form, meaning numerator can NEVER be higher than the demoninator. When you do this process, do not forget to add the whole number or else you will be incorrect.)
(Second note: its not GCF its closest product they have.)
Answer:
6 1/10
Step-by-step explanation:
convert mixed fraction to improper fraction
4 1/2 + 1 3/5
= (4*2 + 1) / 2 + (1*5 + 3) / 5
= 9/2 + 8/5
= lcm of 2 and 5 = 10
= (5 * 9 + 8 * 2) /10
= (45 + 16) /10
= 61/10
= (60 + 1) / 10
= 6 1/10
Hope it helps.
what is the slope of the line
Answer:
slope = 3/2
Step-by-step explanation:
Step 1: Select two points from the graph.
(3,0) and (1,-3) are two points on the graph.Step 2: Apply the formula to find slope- [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].
[tex]\frac{-3-0}{1-3}[/tex] [tex]\frac{-3}{-2}[/tex] [tex]\frac{3}{2}[/tex]Therefore, the slope is 3/2.

Quadrilateral ABCD has the following
vertices:
A(2, 7)
B(8,1)
C(1, -9)
D(-6, -2)
Is quadrilateral ABCD a parallelogram, and
why?
Answer:
No because the angle of point C is NOT congruent to the angle of point A.
Step-by-step explanation:
A quadrilateral MUST be a parallelogram if it has both pairs of its opposite angles congruent.

Help pls, due in 10 mins
Answer:
B. 39
Step-by-step explanation:
134 is a supplementary angle, so 180-134=46. 46 is the bottom left interior angle of the triangle.
Next that 56 and the bottom right exterior angle are supplementary, so 180-56=124.
now we have the bottom right exterior angle, to find the interior 180-124=56.
Then we can set up the equation to find x:
56+46+2x=180
we have 180 because all triangles angle equal 180.
calculate the equation:
combine like terms, (2x)+(56+46)=180
2x+102=180
Subtract 102 from both sides,
180−102=78
2x=78
Divide both sides by 2.
78/2=39
x=39.
Zidan is using the Rational Root Theorem to help find the roots of a 5th degree polynomial. He has discovered five roots and still has 4 to test. What is his next best step?
1-He should test the remaining 4 roots.
2-He should use the Factor Theorem to find the remaining polynomial roots.
3-He needs to pick one of the roots and use the quadratic formula to test it.
4-He can stop testing because he has found all the roots.
Answer:
He can stop testing because he has found all the roots.

HELP ASAP You are preparing to move into a new house. The walls of your room will measure 10 feet by 12 feet.
When you look at the blueprint, the lengths of the walls on the drawing are 7.5 inches by 9 inches. What
is the scale used on the blueprint?
The Scale used on blueprint is 1 inches represents 4/3 feet
Scaling is the increase or decrease in size of a figure or object so as to create an image of that object.
Since on the blueprint, the walls measure 10 feet by 12 feet but on the blue print it measures 7.5 inches by 9 inches. Hence:
Scale used on blueprint is 7.5 inches = 10 feet or 9 inches = 12 feet
1 inches = 4/3 feet
The Scale used on blueprint is 1 inches represents 4/3 feet

Could someone explain how to convert from slope intercept form: y=mx+b to standard form: ax+by=c because I don’t understand
Don’t copy from the internet pls
Answer:
basically you move the y and x to one side and the constant to the other
for example if we had 2y=-5x+6, you'd move the 5x other to the other side by adding 5x and you'd get 5x+2y=6

Y=X^2.
Y=-x^2.
Y=x^2 +2
Y=X^2-2
Y=2x^2
Answer:
y=x^2 is a parabola when y is x squared
y=-x^2 is the first one but when it is flipped over the x axis
y=x^2+2 is the first one shifted two up
y=x^2-2 is the third one but shifted 4 units down
y=2x^2 is the first one but two times the square of x
