-9x = 10 - 2y
-48 = 4x+10y
Answer:
x=−2 and y=−4
Step-by-step explanation:
I will solve your system by substitution.
(Add -4x to both sides)
(Add 48 to both sides)
(Divide both sides by -4)
(Simplify both sides of the equation)
(Add 2y to both sides)
(Add -108 to both sides)
(Divide both sides by 49/2)
(Simplify both sides of the equation)
Answer:
x=−2 and y=−4

Someone plz help me show your work!
Answer:
1/6
Step-by-step explanation:
We know that 1/2 are apples and 1/3 are bananas
we also know that
apples+bananas+oranges=1
Which means that
1/2+1/3+oranges=1
Add 1/2 + 1/3 by getting the denominators equal
3/6+2/6=5/6
Which means that 5/6+oranges=1
1-5/6=1/6
1/6
write everything below this
1/2+1/3+oranges=1
1/2+1/3=5/6
5/6+oranges=1
oranges=1-5/6
oranges=1/6

Pleasee helppp answer correctly !!!!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!!!!
Answer:
(4,7)
Step-by-step explanation:
interest earned:? principal: 250$ interest rate: 4% time: 2 years
First begin with the interest formula.
Interest = Principal x Rate x Time
The $250 is the principal is the amount of money invested.
The rate is 4% which translates to the decimal .04.
The time is 5 years.
So we have I = (250)(.04)(2).
Multiplying, (25)(.04) is 10 and we have 10(2) which is 20.
This means that the interest earned in 2 years is $20.

ABCD is a trapezium
AD=10cm
AB=9cm
DC=3cm
Angle ABC=angled BCD=90degrees
Calculate the length of AC
Give your answer correct to 3 significant figures
Answer:
12.0 cm
Step-by-step explanation:
✔️First, find the height, BC, of the trapezium using Pythagorean Theorem.
BC² = 10² - (9 -3)²
BC² = 10² - 6²
BC² = 64
BC = √64
BC = 8 cm
✔️Find AC using Pythagorean Theorem:
AC² = AB² + BC²
AC² = 9² + 8²
AC² = 145
AC = √145
AC = 12.0415946 ≈ 12.0 (3 significant figures)

Which value of x makes the value of the expression x - 11.5 a negative number?
Answer:
11
Step-by-step explanation:
The absolute value of any positive number is the number itself, so 11 has 11 as an absolute value. Also, the absolute value of a negative number is its (positive) opposite, so also has 11 as an absolute value.
please help i cant figure this out :/
Answer:
6,15
Step-by-step explanation:
A dilation is the changing of a size. A scale factor is a proportional number that tells us how much we change a shape.
If the scale factor is over 1, the new image will stretch.
If the scale factor is under 1, the new image will shrink
Since we are asked to find A' (which is prime notation) meaning that we are asked to find the coordinates where A' is at on the new image.
Since the scale factor is 3,
3 is greater than 1 so it will stretch.
Now, multiply 3 to each number
to find it new location.
[tex] \frac{2}{5} \times \frac{3}{3} = \frac{6}{15} [/tex]
So the coordinates are at 6,15
Answer:
I'm pretty sure you multiply each number in (2,5) by the 3 to get new coordinates of (6,15)
that's the only answer that could fit :)

Triangle ABC is dilated by a scale factor of 1.5 to form Triangle DEF. Are Triangles ABC and DEF congruent? Why or why not?
Answer:
Yes, they will be.
Step-by-step explanation:
Congruent means when they are the same shape and same size.
If triangle ABC is dilated to form triangle DEF, that means that they will have the same shape and the same size.
So yes Triangles ABC and DEF will be congruent to one another because they will be the same shape, and they will have the same size as well.

HELP “The vertical supports in this truss bridge are built so that
AABO=AOCD. Which of the following statements
is NOT true?”
Answer:
The statement that is not true is;
c) m∠ABO = m∠ODC
Step-by-step explanation:
With the assumption that the lengths AO, and OD are equal, we have that in ΔABO and ΔOCD, the following sides are corresponding sides;
Segment AO on ΔABO is a corresponding side to segment OD on ΔOCD
Vertices B and C on ΔABO and ΔOCD are corresponding vertices
Therefore;
Segments AB and OB on ΔABO are corresponding sides to segments OC and OD on ΔOCD respectively
Therefore, ∠ABO on ΔABO is the corresponding angle to ∠OCD on ΔOCD
Given that ΔABO ≅ ΔOCD, we have that ∠ABO ≅ ∠OCD
Therefore;
m∠ABO = m∠OCD by definition of congruency
