A rectangular flower bed is enlarged so that its area increases by 15 yd².

1 answer:

6 0

First, we subtract 15 yd² from the area given. Doing so, will give us an answer of,
x² + 8x
This expression can be factored out as (x + 8)(x). Thus, the dimensions of the flowed bed before its area is increased by 15 yd² are (x + 8) yd and (x) yd.

Line CD passes through points C(3, -5) And D(6, 0). What is the equation of line CD in standard form?

Fynjy0 [20]

Y = mx + b
m = (0 - -5)/(6 - 3) = 5/3
y = 5/3x + b
0 = 5/3(6) + b
b = -10
(y = 5/3x - 10)3
3y = 5x - 30
3y - 5x = -30
5x - 3y = 30

Can somebody help me asap?

Oduvanchick [21]

Answer:

44%

Step-by-step explanation:

First, take that pretty figure and align it into complete rows.

It will make 2 full rows plus one block.

1 row is 20% since 100 / 5 blocks is 20.

That's 11 blocks.

11 / 25 = .44 or 44%

Every triangle in the figure at right is equilateral. What is the measure of ∠AGE?

Andrew [12]

Answer:

120°

Step-by-step explanation:

All the angles of an equilateral triangle are equal, and hence have a measure of 60°.

∵ ∠AGF is a part of equilateral Δ AGF, m∠AGF = 60°.

∵ ∠FGE is a part of equilateral Δ AGF, m∠FGE = 60°.

Also note that ∠AGE = ∠AGF + ∠FGE.

⇒ m∠AGE = m∠AGF + m∠FGE

⇒ m∠AGE = 60° + 60°

= 120°.

Please help this is hard math

Rainbow [258]

Answer:

$y=-4x+2$

Step-by-step explanation:

First we find the slope of the line AB passing through the point (2,0)
line AB is perpendicular to the line $y=\frac{1}{4}x-3$ , this equation is slope intercept for, which is $y=mx+b$ so our m or slope is $\frac{1}{4}$
Since the slope of line AB is perpendicular to $m=\frac{1}{4}$ then we use the equation $slope of line1\times slopeofline2=-1$ , so what do we multiply $\frac{1}{4}$ by to get -1? -4 right, so that's the slope of line AB with the point (2,0)
Now line CD is parallel to line AB, that means it has the same slope as AB, so slope of CD is -4
So we make the equation $y-y_1=m(x-x_1)$ so m= -4 and our point is (-1,6)
$y-(6)=-4(x-(-1)\\y-6=-4x-4\\y=-4x-4+6\\y=-4x+2$ thats the equation of line side CD
