X=16-4y. systems of equations 3x+4y=8<br> substitution
alina1380 [7]

Answer:

x=-4  y=5

Step-by-step explanation:

Rewrite equations:

x=−4y+16;3x+4y=8

Step: Solvex=−4y+16for x:

x=−4y+16

Step: Substitute−4y+16forxin3x+4y=8:

3x+4y=8

3(−4y+16)+4y=8

−8y+48=8(Simplify both sides of the equation)

−8y+48+−48=8+−48(Add -48 to both sides)

−8y=−40

−8y

−8

=

−40

−8

(Divide both sides by -8)

y=5

Step: Substitute5foryinx=−4y+16:

x=−4y+16

x=(−4)(5)+16

x=−4(Simplify both sides of the equation)

Answer:

x=−4 and y=5

The temperature is -3 F at 7:00 am During the next 4 hours the temperature increases 21 F. What is the temperature at 11:00am ?
telo118 [61]
Now what you want to do is 21 + (-3). Since this is the same as saying 21 - 3, the answer is 18. Therefore, the answer is 18°F.

A parabola and a circle are graphed into the standard (x,y) coordinate plane. The circle has a radius of 4 and is centered at (1
Gala2k [10]

Answer:

Correct answer: Two point of intersection and one touch point.

Step-by-step explanation:

Cartesian form of parabola is: y= a(x-1)² + 5  and point named A(2,4)

when we replace the coordinates of the point A in the formula we get

a = - 1 and parabola is  y= - (x-1)² + 5 which means that it faces the opening downwards. The parabola touches the circle in vertex.

God is with you!!!

Ilya [14]

Given:

The number is -\dfrac{7}{5}.

To find:

The location of the given number of the number line.

Solution:

We have,

Number=-\dfrac{7}{5}

It can be written as

Number=-\dfrac{5+2}{5}

Number=-\dfrac{5}{5}-\dfrac{2}{5}

Number=-1-\dfrac{2}{5}

It means the number is less than -1 but more than -2. So, the number lies between -2 and -1.

The mixed fraction form of given number is

Number=-(1+\dfrac{2}{5})

Number=-(1\dfrac{2}{5})

Number=-1\dfrac{2}{5}

Divide the number in 5 equal parts between two consecutive integers.

Now each unit represents \dfrac{1}{5}.

Since Number=-1-\dfrac{2}{5}, therefore, it is 2 units left from -1.

The number line is given below.
