If a solution(s) exists y=y so we can say:

x^2-3x=-2x+2  add 2x to both sides

x^2-x=2  subtract 2 from both sides

x^2-x-2=0  factor

(x-2)(x+1)=0

So x=-1 and 2, using y=-2x+2 we find:

y(-1)=4 and y(2)=-2

So the two solutions occur at the points:

(-1,4) and (2,-2)

Find the surface area of the pyramid round to the nearest tenth choose the correct unit
sineoko [7]

slant height(h) = 16.3ft

Base side = 20ft

\text{Area of pyramid=}\frac{1}{2\text{ }}\times perimeterofbase\text{ x slant height}

Perimeter of base = 4(base side) = 4(20) = 80ft

\begin{gathered} \text{Area of pyramid = }\frac{1}{2}\times80\times16.3 \\ \text{Area = }652ft^2 \end{gathered}

Find the y-intercept of the line -4× - 2y =16​
Oksi-84 [34.3K]

Answer:

The y intercept is (0,-8)

Step-by-step explanation:

To find the y intercept, set x = 0 and solve for y

-4x -2y = 16

-4(0) -2y =16

-2y = 16

Divide by -2

-2y/-2 = 16/-2

y = -8

The y intercept is (0,-8)

Approximate: log5 4/7
Evgesh-ka [11]
   Properties of Logs

logb(x/y) = log<span>bx</span> - log<span>by</span>.

therefore

log5 (4/7)= log5 (4)- log5 (7)

<span>Solve log 5 (4) and log 5 (7)  with the base change of the logarithm</span>

<span>log 5 4 = log 4 / log 5 </span>

 Use the calculator: 

<span> <span>log 5 4 =0.8613531161 </span></span>

 log 5 7 = log 7 / log 5 

<span>log 5 7 =1.2090619551</span>

<span>log5 (4/7)= log5 (4)- log5 (7)=-0.347708839</span>
