find the numerical value of the following expression X+y-z, when X=3,y=-2 and Z=-9
Answer:
10
Step-by-step explanation:
after substituting in the values of each variable, the expression becomes..
3 + (-2) - (-9)
= 3 - 2 - (-9)
= 1 - (-9)
= 1 + 9 = 10
A line passes through the point (-8,4) and has a slope of . -5/2
Write an equation in slope-intercept form for this line.
Answer:
Y= -5/2x +16
Step-by-step explanation:
To solve this, understand that (-8,4) is (x,y)
And Slope intercept form is y=mx +b
Since you have a possible x and y with - 8 and 4, sub that in making it 4=m(-8) + b
We also have the Slope (or M) which is -5/2, sub that in and get 4 = -5/2 (-8) + b
Do the multiplication and get 4= 40/2 +b
Simplify to 4= 20 + b
Then re-arrange to have the unknown (b) on one side and known on the other (when you move a number over the equal sign its sign, positive or negative, becomes the opposite)
B= 20-4
Subtract
B= 16
Now you know the b and can add it to your equation,
Y= -5/2x +16
Answer:
y = -5/2x - 16.
Step-by-step explanation:
First use the point-slope form of a line:
y - y1 = m(x - x1)
y - 4 = -5/2(x - (-8))
y - 4 = -5/2x - 40/2
y = -5/2x - 20 + 4
y = -5/2x - 16.

A line passes through the point (7,9) and has a slope of 2.
Write an equation in slope-intercept form for this line.
Answer: y = 2x - 5
Step-by-step explanation:
slope- intercept form is always written as y = mx + b, where m = slope, and b is the y-intercept.
To find b, substitute the point and the slope into the equations, you will get:
y = mx + b
9 = 2(7) + b
9 = 14 + b
-5 = b
Plug in m and b into the equation, we get:
y = mx + b
y = 2x + (-5)
y = 2x - 5

In a two digit number. the unit digit is thrice the tens digit. if 36
is added to the number, the digits interchange their place. find the number
Answer:
Step-by-step explanation:
answer: the original number is 62.
Given :
Units digits is thrice the tens digit
The digits interchange when - 36 is added
To find :
The number
Solution :
✯
Let the digits be -
Units place as 3y
Tens place as 10(y)
⇒ 10(y) + 3y
⇒ 10y + 3y
⇒ 13y --------- (Orignal Number)
✯
Let the digits be -
Units place as y
Tens place as 10(3y)
⇒ 10(3y) + y
⇒ 30y + y
⇒ 31y --------- (Number with reversed digits)
✯
The number gets reversed when 36 is added to it.
⇒ 13y + 36 = 31y
⇒ 13y - 31y = - 36
⇒ 18y = 36
⇒ y = 36/18
⇒ y = 2
✯
⇒ 13y
⇒ 13(2)
⇒ 26
✯
The units place should be thrice of the tens place,
⇒ 2 × 3 = 6
Units place is 6
Reversed digits are 62,
⇒ 26 + 36 = 62
⇒ 62 = 62
The Orignal Number is 62.

The equation is y=mx+b.
My question is, is ‘b’ supposed to be in decimal form or in fraction form??
Answer: both ways are acceptable
Step-by-step explanation: When writing equations of lines in this form,
we usually keep the "b" value or the constant term as a fraction.
However, if you prefer decimals, you can absolutely change
it to a decimal to visualize is better if you'd like, it's really your choice.
For example, if the equation of a line was y = -3/4x - 7/4, I could leave
it how it is or I could change the -7/4 to -1.75 giving me y = -3/4x - 1.75.
Which is the point-slope form of a line that has a slope of -4 and passes through point (-3,1)?
Hi!
The point-slope formula looks like this:
y-y1=m(x-x1)
in this case
y1=1
m=-4
x1=-3
plug in the values
[tex]\boxed{\boxed{\bold{y-1=-4(x-(-3)}}}[/tex]
Note:
For Point-Slope Form, we use a point that the line passes through and the slope of the line.
Actually, that's why it's called "Point-Slope Form" right? =)
Hope everything is clear.
Let me know if you have any other questions; if so, please feel free to use the comment section.

Find the value of xx, yy, and zzz in the rhombus below.
Answer:
x = 13; y = 13; z = 18
Step-by-step explanation:
In a rhombus, opposite angles are congruent and consecutive angles are supplementary.
6x + 8 = 86
6x = 78
x = 13
7y + 3 + 86 = 180
7y + 89 = 180
7y = 91
y = 13
5z + 4 + 86 = 180
5z + 90 = 180
5z = 90
z = 18

a cell phone tower services about 1,256sq. miles what is the radius?
Start with the formula for finding the area of a circle.
A=πr2
First, substitute the given information in the equation. You have the area and you know that pi is 3.14.
153.86=(3.14)r2
Next, divide the area by pi. This will help to get one step closer to figuring out the radius.
3.14)153.86¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
Remember, when you divide decimals, to move the decimal two places in the divisor and the dividend.
314)15386¯¯¯¯¯¯¯¯¯¯¯¯¯¯
314)15386¯¯¯¯¯¯¯¯¯¯¯¯¯¯ 49− 1256 –––––––– 2826 − 2826–––––––0
So far, the answer is 49, but that is not the radius because r2 is on the right side of the equal sign.
49=r2
Then, you need to figure out which number times itself is equal to 49. You can figure this out by finding the factors of 49.
7×7=49
Now, you know that the radius is 7 inches because 7×7=49.
The radius is 7 inches.
Finally, to figure out the diameter, which is twice the radius, multiply the radius by 2.
7×2=14
The diameter is 14 inches.
hope this helps.
The radius covered by the tower will be 20 miles.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.
Given that a cell phone tower services about 1,256sq. miles. The area of the circle will be calculated by the formula,
Area = πr²
1256 = π x r²
r² = ( 1256 / π )
r² = 400
r = √400
r = 20 miles
Hence, the radius of the circle will be 20 miles.

the hire purchase of a car is 680000 naira. there is a deposit of 12.5 percent. the remainder is spread over 12 equal monthly instalment. find the deposit , calculate the remainder to be paid and find the amount of each monthly instalment to the nearest naira
Answer:
Step-by-step explanation:
I am not sure why there is no interest rate given as it is common that there will be an interest charge for a monthly installment plan.
Assuming it is an interest-free plan, the remainder payment is for an amount of:
680000*(1 - 12.5%)
= 680000*(0.875)
= 595000 naira
Dividing that into 12 equal monthly, each monthly installment is
595000/12 = 49583.33
~49583 naira
