Hey there!
The answer to your question is [tex]4x^2+2x-2[/tex]
Given:
[tex]x^2-3x+7[/tex] [tex]and[/tex] [tex]3x^2 +5x-9[/tex]
First, we can start by adding like terms. The following are like terms:
[tex]x^2[/tex] [tex]and[/tex] [tex]3x^2[/tex]
[tex]-3x[/tex] [tex]and[/tex] [tex]5x[/tex]
[tex]7[/tex] [tex]and[/tex] [tex]-9[/tex]
Now, we can add these pairs together, giving us:
[tex]4x^2[/tex]
[tex]2x[/tex]
[tex]-2[/tex]
Now, add all this together, and we get our answer as:
[tex]4x^2 + 2x - 2[/tex]

Hassan plotted point M in the coordinate plane below.
On a coordinate plane, Point M is 0.5 units to the left and 0.25 units down.
He says that the plotted point is (0.5, 0.25). What is Hassan’s error?
The x- and y-coordinates are switched.
Both coordinates should be negative.
The x-coordinate should be -2.
The y-coordinate should be -1.
Answer:
Both coordinates should be negative
Step-by-step explanation:
When you go to plot a point, you always start at (0,0). Since you go left 0.5 units, that would put you at -0.5, then you go down 0.25 units which would put you at (-0.5, -0.25). The result would be (-0.5, -0.25). Hope this helps! :)

Answer:
x = 130 degrees
Step-by-step explanation:
We know that the total angle equals to 180 degrees since it is a straight line
Therefore, 25 + 25 + x = 180
180 - 25 - 25 = 130
Therefore, x = 130 degrees
Plz mark brainliest :D
Step-by-step explanation:
As we know that sum of all angles on a straight line is 180°
thus,
25°+x+25° = 180°
=> x + 50° = 180
=> x = 180° - 50°
=>. x = 130°

2. Rohan spends x daily and saves y per day. What is his income after 3 weeks?
Step-by-step explanation:
Amount of money spend in 1 day = x
So, amount of money spend in 7 days = (7x)
⇒ Amount of money spend in 1 week = (7x)
Amount of money saved in 1 week = y
∴ Income in 1 week = (7x + y)
So, income in 3 weeks = [3 x (7x + y)]
= (21x + 3y)
Answer:
total income after 3 weeks=7×3(x+y=21x+21y
income=saving + expenses

Answer: 8/9
Step-by-step explanation:
The common multiple they all share is 18, so change the denominator to that for all the fractions.
2/3 = 12/18
13/18 = 13/18
7/9 = 14/18
5/6 = 15/18
The next answer would be 16/18 which is equivalent to 8/9
Answer:
12/18,13/18,14/18,15/18
the next would be 16/18=8/9

If the cost of manufacturing mobile phones is $10,000 for the factorytime plus $80 per phone and that each
phone sells for $100, how many phones must be manufactured for the mobile phone manufacturer to
break even (when costs equals revenue)?
Answer:
500 phones
Step-by-step explanation:
cost of manufacturing: y = 80x + 10,000
money from phone sales: y = 100x
* note: x = #phones
solve for when they're equal;
100x = 80x + 10,000
100x - 80x = 80x - 80x + 10,000
20x = 10,000 –––––––––––> divide both sides by 20
x = 500

A remodeling project calls for sanding a chair with a disk sander. The sanding disk used on the sander has a radius of 4 inches. Find the area of the disk. Use 3.14 for \large \pi
Answer:
the area of the disk is 50.24 inches^2
Step-by-step explanation:
The computation of the area of the disk is as follows:
As we know that
The area of the circle is
= πr^2
= 3.14 × 4^2
= 3.14 × 16
= 50.24 inches ^2
hence, the area of the disk is 50.24 inches^2

Find the measurement of angle ABC
Answer:
x=97° a=97° b=97°
Step-by-step explanation:
83°+a=180° (by linear pair)
a=180°- 83°
a=97
and a=x°(by corresponding angle)
x= 97°
x=b(by vertical opposite angle)
b = 97°

Answer:
A. 2[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
You have to replace x with one of the values in the set. You have to find the one that works.
3[tex]\frac{1}{2}[/tex]x = 8[tex]\frac{3}{4}[/tex]
8[tex]\frac{3}{4}[/tex] ÷ 3[tex]\frac{1}{2}[/tex] = x

8 to 14
8 to 6
6 to 14
6 to 8
Answer:
8 to 6
Step-by-step explanation:
The question is asking what is the ratio of "tablespoons of raspberries" TO ratio of "tablespoons of sugars".
= 8 tablespoons of raspberries TO 6 tablespoons of sugar
= 8 (tablespoons of raspberries) TO 6 (tablespoons of sugar)
= 8 TO 6
The ratio of tablespoons of raspberries to tablespoons of sugar should be considered as the 8 to 6.
Calculation of the ratio:Since Macy's aunt makes raspberry jam using 6 tablespoons of sugar and 8 tablespoons of raspberries.
So here the ration be like
= 8 raspberries tablespoons to 6 tablespoons of sugar
= 8 to 6
hence, the second option is correct.

x = 70°, y = 30°, z = 20°
Step-by-step explanation:
Right triangle have a total internal angle of 180°.
x = 180° - 110°
= 70°
z = 180° - 90° - x
= 180° - 90° - 70°
= 20°
y = 180° - 40° - 90° - z
= 180° - 40° - 90° - 20°
= 30°

Answer:

b. 17/36

e. 19.8
Step-by-step explanation:
Hope this helped!
Answer:
a. 18 b. 15/64 c. 122 2/9 d. 157.5615 e. 19.8
Step-by-step explanation:
a.
b. multiply across, so 1 * 15 = 15, 4*16=64, 15/64 can't be reduced, so done
c. 13 3/4 * 7 8/9, you must convert to improper fractions to multiply
4*13+3 = 55 so the first part is 55/4, 7*9+8=80 so the second is 80/9
55/4 * 80/9 = (55*80) / (4*9) = 4400 / 36, both are divisible by 4 so can be reduced to 1100/9 which cannot be reduced any further, 1100 + 9 = 122 R 2 so
1100/9 = 122 2/9
d. used calculator
e. 33% of 60 = (33//100)*(60/1) = (33*60) / (100*1) = 1980 / 100 = 19.8
