Answer:
i think you had written the formula wrongly
so if it was -30x not -30
Step-by-step explanation:
x intercept when y=0
-30x = 15
x= -0.5
y intercept when x=0
5y= 15
y=3
- if this is the one you want
-30 +5y=15
5y =45
y=9
and there not x intercept { }
Write an equation of line in point slope form containing (-1,1) and (4,-9)
Help!!!!!!!!!!!!!!!!!
9Answer: Y-1=-2(X+1) OR Y+9 = -2(X-4)
Step-by-step explanation:
Point slope form is Y-Y1=m(X-X1)
Slope (M) is (Y2-Y1)/(X2-X1)
SO M= (-9-1)/(4--1)
-10/5
M= -2
Answer:
y - 1 = -2 (x + 1)
Explanation:
point slope form: (y - y1) = m (x - x1)
m is the slope. To find m the formula is:
(y2 - y1) / (x2 - x1)
The given ordered pairs are: (-1,1) and (4,-9)
y2 is the y in the second ordered pair (-9)
y1 is y in the first ordered pair (1)
x2 is x in the second ordered pair (4)
x1 is x in the first ordered pair (-1)
= (-9 - 1) / (4 +1)
= -10/5
m = -2
Now plug m (-2), y1 (1), and x1 (-1) into the point slope form
y - 1 = -2 (x - -1)
y - 1 = -2 (x + 1)
Three equal-sized cardboard boxes are stacked on top of each other. Each box is 56.4 cm in height.
What is the combined height of the 3 stacked boxes?
18.8 cm
59.4 cm
112.8 cm
169.2 cm
Answer:
169.2cm
Step-by-step explanation:
56.4cm + 56.4= 112.8+ 56.4= 169.2cm
The combined height of the 3 stacked boxes will be 169.2 cm so option (D) will be correct.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given that,
Height of one box = 56.4 cm
So,
Height of two boxes = Height of one box + Height of one box
It means
Height of three boxes = Height of one box + Height of one box + Height of one box
So,
Height of three boxes = 56.4 + 56.4 + 56.4
Height of three boxes = 169.2 cm
Hence "The combined height of the 3 stacked boxes will be 169.2 cm".

You might want to specify which variable you are solving for...
what values of a and b would make shown below have infinitely many solutions aX +6=-3x+b
Answer:
a = -3, b = 6
Step-by-step explanation:
ax + 6 = -3x + b
If a = -3 and b = 6, then the equation would be -3x + 6 = -3x + 6, which would have infinitely many solutions.
If we isolate x, we have (a + 3) x = b - 6. We want the equation to be 0 = 0 for infinitely many solutions, so a has to be -3 and b has to be 6.

evaluate the expression
Answer:
32
Step-by-step explanation:
We are given the expression:
[tex]\frac{-8(13-37)}{6}[/tex]
and asked to evaluate the expression.
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
Solve inside the parentheses first. Subtract 37 from 13.
⇒ 13-37= -24
[tex]\frac{-8(-24 )}{6}[/tex]
Next, multiply -8 and -24.
⇒ -8*-24= 192
[tex]\frac{192}{6}[/tex]
Finally. divide 192 by 6.
⇒ 192/6 = 32
[tex]32[/tex]
When evaluated, the expression -8(13-37)/6 is equal to 32.

3.)
•What do you know?
-It’s about 425 miles from San Jose to Los Angeles and 320 miles from San Jose to Santa Barbara.
•What do you want to find out?
-How many miles it is from Santa Barbara to Los Angeles.
•What kind of answer do you expect?
-If using variable, I expect that I will get the number of miles from one city to the other.
5.)
425 = 320 + X
6.)
425 = 320 + X

7.)
X = 105
From Santa Barbra to Los Angeles it is 105 miles.
8.)

Ashley is looking for ways to save some spending money for her senior class trip to Mexico. She has decided to
stop eating chocolate for one whole year and instead save any money she would have spent on chocolate for the
trip. If Ashley typically spends $2.50 a week on chocolate, how much money, not accounting for interest, can she
expect to save for the trip in exactly one year? $|||
Answer:
She would have 130 dollars
Step-by-step explanation:
There are 52 weeks in a year. So multiply 2.50 by 52. She would have 130 dollars.
Ashley can expect to save $130 for the trip in exactly one year.
Ashley decided to stop eating chocolate for one whole year to save some spending money for her senior class trip to Mexico.
The amount Ashley typically spends a week on chocolate = $2.50.
We have to find how much Ashley can save in one year if we can save $2.50 per week.
How many weeks in a year?There are 365 days in a year and we have 7 days in a week.
If we divide 365 by 7 we get,
365 / 7 = 52.14.
which means 52 weeks.
So in one year, we have 52 weeks.
We can write this statement "Ashley typically spends $2.50 a week on chocolate" as :
1 week = $2.50
Multiply by 52 on both sides.
we get,
52 x 1 week = 52 x $2.50
52 weeks = $130
Thus, we can say that in one year Ashley can save around $130 if she saves $2.50 in a week.

Segment EC bisects segment AD at C. Find the value of “x," AD = 6x - 4 and AC = 4x - 3, and the measure of CD.
Answer: The value of x=1.
Measure of CD =1 unit.
Step-by-step explanation:
Given: Segment EC bisects segment AD at C.
That means , EC divided AD into two equal parts AC and CD,
i.e. [tex]AC=\dfrac{AD}{2}[/tex]
Also it is given that [tex]AD = 6x - 4[/tex] and [tex]AC = 4x - 3.[/tex]
then, we have
[tex]4x-3=\dfrac{6x-4}{2}\\\\\Rightarrow\ 4x-3= 3x-2\\\\\Rightarrow\ 4x-3x=-2+3\\\\\Rightarrow\ x= 1[/tex]
So, the value of x=1.
Now, CD = AC = 4(1)-3 =4-3 =1 unit.
Hence, Measure of CD =1 unit.

I really don’t get how to this at all like I really don’t get it I need some help
Answer:
no solution
Step-by-step explanation:
Given
4 + x = 3(x + 2) - 2x ← distribute and simplify right side
4 + x = 3x + 6 - 2x
4 + x = x + 6 ( subtract 4 from both sides )
x = x + 2 ( subtract x from both sides )
0 = 2 ← not possible
This indicates the equation has no solution

Answer: x=-6
Step-by-step explanation:

9x+27=4x-3 ⇔ distributive property (take off parentheses)
5x+27=-3 ⇔ subtraction property of equality (subtract 4x on both sides)
5x=-30 ⇔ subtraction property of equality (subtract 27 on both sides)
x=-6

Corrected Question:
The length of a rectangle is (t – 8) units, and its width is (t + 11) units. Which expression can represent the area of the rectangle?
Answer:
t² + 3t - 88
Step-by-step explanation:
Given:
Rectangle of;
length = (t - 8) units
width = (t + 11) units
The area A of a rectangle is given by;
A = length x width ----------------------------------(i)
Substitute the given length and width into equation (i) as follows;
A = (t - 8) x (t + 11) [expand the brackets]
A = t² -8t + 11t - 88
A = t² + 3t - 88
Therefore, the area is
(t² + 3t - 88) square units
