Answer:
Move all terms to the left side of the equation and simplify.
4x²+7x−2=0
Use the quadratic formula to find the solutions.
(−b±√b2−4(ac))/2a Substitute the values a=4 , b=7, and c=−2 into the quadratic formula and solve for x.
(−7±√72−4⋅(4⋅−2))/2⋅4 Simplify.
x=−(7±9)/8 .The final answer is the combination of both solutions.
x=1/4,−2

1. For AEFG shown below, construct the median from E to side FG. Leave all construction marks.
can somebody please describe where i put the construction marks? it’d be really helpful.
Answer:
Step-by-step explanation:
A median bisects the side it intersects with, so the first step is to bisect FG.
Set the compass slightly larger than half of FG.
Put the point on F and draw a half circle that intersects FG and faces G.
Put the point on G and draw a half circle that intersects FG and faces F.
Draw a line through the intersections of the two half circles, and the intersection of that line with FG is FG's midpoint.
Connect the midpoint with E, and the connecting line is the median.
Find the value of z.
What is the range of the function shown in the graph below?
Answer:
y= -3/2X + 2
Step-by-step explanation:
we get the gradient by picking any two points from the graph( it a linear graph)
using the point:
(x,y)= (-2,5) , (4,-4)
using M= (y2-y1)/x2-x1)
we get our gradient to be -9/6 which is
-3/2
using the equation of a straight line graph which is
y-y1=m(x-x1) and the point (4,-4)
we get
y-(-4)=-3/2(x-4)
----> y+4= -3/2x + 6
make y subject of the formula to take the form
y=mx+c
we get :
y=-3/2x + 2

Answer:
x= 12
Step-by-step explanation:
The solution is, he bought 3 bags of carrots and 8 bags of tomatoes.
What is equation?An equation can be stated as a mathematical statement that is made up of two expressions connected by an equal sign. In its normal form in algebra, it can be said as of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
Mark spent a total of $16.35 to buy a total of 11 bags of carrots and bags of tomatoes.
Each bag of carrots costs $1.05, and each bag of tomatoes costs $1.65.
let, he bought x bags of carrots and y bags of tomatoes.
now, we get,
x+y = 11 ....(1)
1.05x + 1.65y = 16.35 ....(2)
solving this, we get,
x= 3
y= 8
Hence, The solution is, he bought 3 bags of carrots and 8 bags of tomatoes.

Hi!! Whats 5+5+6355334+64-463454432/2?
Answer: 414628192
Step-by-step explanation: ok, so take 5+5=10
10+ 6355334= 6355344 + 64= 6355408
then do 463454432/2 which = 231727216 then
646355408-231727216= 414628192

Step-by-step explanation:
y=30
y=0.5x+5
you would take 30÷0.5=60
0.5x60+5
30+5=35
x=35

Step-by-step explanation:
A triangle equals 180º so to find x, just subtract the other angles from 180
180 - 39 - 84 = 57
Step-by-step explanation:
x+39+84=180 (being sum of angle of triangle is 180)
x+123=180
x=57

A rectangle has coordinates (2, 6) (9, 6) (9, 10) and (2, 10) on a grid with 1 cm squares. What is the area of the shaded rectangle?
Answer:
Area of Rectangle = 28 cm²
Step-by-step explanation:
Given - A rectangle has coordinates (2, 6) (9, 6) (9, 10) and (2, 10) on a grid with 1 cm squares.
To find - What is the area of the shaded rectangle?
Solution -
The graph of the rectangle is as follows :
From the diagram, e can see that
Length of Rectangle = 7 units (cm)
Breadth of Rectangle = 4 units (cm)
We know that,
Area of Rectangle = Length × Breadth
= 7 × 4
= 28 cm²
⇒Area of Rectangle = 28 cm²

Step-by-step explanation:
what is 4 + 78908 + 54732927 - 7 + 45678?
Answer: the answer is: 54857510
Step-by-step explanation:
What i had just did was i just broke the equation into 2 parts: so i did first (4 + 78908 + 54732927 - 7) which gave me 54811832. Then i did the next part which was adding 45678 in the mix ( 54811832 + 45678 = 54857510) So, the number from which you are left with is 54857510.
((TIP: Next time when you see problems like this, break them down into smaller equations so it will be much easier for you to solve, and its much more quicker and less harsh on your brain rather then just trying to do in all in one shot))

HELP PLEASE HELP!!!!
Answer:
a=12 b=9
Step-by-step explanation:
u can substitute 3/4a in for b in a+b=12 since it is equal to b, giving you
a+3/4a=21
a=4/4a
4/4a+3/4a=21
7/4a=21
4/7(7/4a=21)
a=12
plug in 12 for a in either equation
b=3/4*12
b=9
(21=12+b) -12
9=b
