the greatest solution of x in the equation x^2+8x−30=18
Answer:
The two possible outcomes are 4 and -12, so 4
Step-by-step explanation:
The greatest value of x is 4.
What is factorization?
Factorization is when you break a number down into smaller numbers that, multiplied together, give you that original number. When you split a number into its factors or divisors, that's factorization.
Given equation
⇒ [tex]x^{2} +8x-30 = 18[/tex]
⇒ [tex]x^{2} +8x-30-18=0[/tex]
⇒ [tex]x^{2} +8x-48=0[/tex]
⇒ [tex]x^{2} +12x-4x-48=0[/tex]
⇒ [tex]x(x+12)-4(x+12)=0[/tex]
⇒ [tex](x+12)(x-4)=0[/tex]
x = -12 and x = 4
Hence, the greatest value of x is 4.

Answer:
A
Step-by-step explanation:
since it is on sale for 27%, multiply $28 by 70% (0.7) to find the total amount of money the shirt costs now that it is on sale (since it's on sale for 30% off)
$28*0.7=$19.60
Answer:
$19.60
Step-by-step explanation:
First, find 30% of $28. :)
To do this, multiply 28 by 0.3. (30% is the same thing as 3/10 or 0.3)
28 x 0.3 = 8.4.
30% of 28 is 8.4.
Next, subtract $8.4 from $28. (Shirt on sale for 30% off)
28 - 8.4 = $19.60

Team D's car went the same distance on each of its trials. Team C's car went exactly 1 cm farther in each trial than Team D's car. Team C's car went 543 cm in all.
Answer:
180 cm
Step-by-step explanation:
Number of trials per team = 3
Distance per trial for team D's car is the same for each trial, let distance = x
Distance per trial for team C's car is 1cm farther than team D's distance and the same for each trial, hence, distance = x + 1 per trial
Total distance traveled by C = 543 cm
This means :
(x + 1) + (x + 1) + (x + 1) = 543
3x + 3 = 543
3x = 543 - 3
3x = 540
x = 540 / 3
x = 180
Hence, distance traveled per trial for team D's car = x = 180 cm
Help! ( i'll give brainlisy ) if you don't know the answer then don't type a "answer" and no sending links please.
Answer: Linear
The equation is y = 2x-5
Slope = 2
y intercept = -5
====================================================
Explanation:
Each time x goes up by 1, y increases by 2. This directly leads to a linear equation due to the same rate of change no matter where you are in the table.
The slope is rise/run = 2/1 = 2 because "y increases by 2 each time x increases by 1".
We could use the slope formula to see this. Pick on any two rows to plug in the coordinates. I'll use the last two rows
m = (y2-y1)/(x2-x1)
m = (3-1)/(4-3)
m = 2/1
m = 2
This confirms the slope is 2.
The positive slope means that the line goes uphill as you move from left to right.
---------------
The y intercept is b = -5 because the y intercept always happens when x = 0. This applies to any function, whether it's linear or not.
Together with m = 2 as the slope and b = -5 as the y intercept, we go from y = mx+b to y = 2x-5 as our linear equation
As a way to check, plug in something like x = 1 to find that...
y = 2x-5
y = 2*1-5
y = 2-5
y = -3
The table shows that x = 1 and y = -3 pair up together in the same row, so that confirms x = 1. I'll let you verify the other x values.

is 9e+2(e+5) and 11e+5 equivalent?
No,
[tex]9e + 2(e + 5) = 11e + 10[/tex]
And 11e + 10 is not equivalent to 11e + 5
Answer:
No, its not.
9e + 2(e+5)
= 9e + 2e + 10
= 11e + 10
---> 9e+2(e+5) when simplified gives 11e + 10.
---> Therefore, its not equal to 11e + 5
A card is drawn randomly from a deck of 52 cards.
Find the probability of getting red faced card.
The probability of drawing a red face card from a deck of cards is 3/26
Explanation:
In a deck of cards, there are 6 red-faced cards.
Probability = No. of favourable events / Total no. of events
So, the probability of drawing a red-faced card is 6 out of 52 cards.
Thus, the probability of drawing a red face card from a deck of cards is 6/52 = 3/26.

Step-by-step explanation:
Answer:
139.5º
Step-by-step explanation:
The sum of supplementary angles is 180º
s + 40.5 = 180
Subtract 40.5 from both sides
s = 139.5º

What does x=_____ degrees
Answer:
x = 48 degrees
Step-by-step explanation:
This triangle is an isosceles which means that two of the angles are the same and all triangles add up to 180 degrees so we take the two angles we know and add them
66 + 66 = 132
Then we subtract that number from 180 to find the third angle
180 - 132 = 48
Answer:
x = 48°
Step-by-step explanation:
Since the legs of the triangle are congruent then the base angles are congruent, both 66° , then
x = 180° - (66 + 66)° = 180° - 132° = 48°
In the diagram, parallel lines P and Q are cut by transversal R.
(2x + 40°
(3x - 85)°
What is the value of x?
Answer:
x=125
Step-by-step explanation:
Using the definition of supplementary angles, the value of x in the given diagram is: 45.
What are Supplementary Angles?Supplementary angles equals 180 degrees when added together.
(2x + 40)° and (3x - 85)° are supplementary angles. Therefore:
(2x + 40) + (3x - 85) = 180
Solve for x
2x + 40 + 3x - 85 = 180
Add like terms
5x - 45 = 180
5x = 180 + 45
5x = 225
x = 225/5
x = 45
The value of x is: 45.
