I need major help. I have a lot of missing work and really need help with algebra 1. (solving linear equations)

1 answer:

A= 5 + 2 = 7
You get this by doing the inverse operation so minus 2 by 2 and 7 then you get your answer so it should look like this
X+2= 7
-2. -2
———
X= 5

B: 15-4=11
+4. +4
————-
X= 15

C: 4(3) = 12

D: 50/5 = 10

Btw this should be easy, try doing it on to your own now.

Answer:

4 quarters

10 tenths

Step-by-step explanation:

<h3>Tenths</h3>

$\frac{1}{10}$

<h3>Quarter</h3>

$\frac{1}{4}$

<h3>Whole</h3>

$1$

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

$1 = \frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}$

∴ There are <u>4</u><u> </u><u>quarters</u> to make a whole

$1 = \frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}$

∴ There are <u>10</u><u> </u><u>tenths</u><u> </u>to make a whole

Is the given point interior , exterior, or on the circle k (x+2)2 + (y-3)2 =18 P (8,4)

Mnenie [13.5K]

One way would be to find the distance from the point to the center of the circle and compare it to the radius

for
$(x-h)^2+(y-k)^2=r^2$
the center is (h,k) and the radius is r

and the distance formula is
distance between $(x_1,y_1)$ and $(x_2,y_2)$ is
$D=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$

r=radius
D=distance form (8,4) to center

if r>D, then (8,4) is inside the circle
if r=D, then (8,4) is on the circle
if r<D, then (8,4) is outside the circle

so
$(x+2)^2+(y-3)^2=18$
$(x-(-2))^2+(y-3)^2=(\sqrt{18})^2$
$(x-(-2))^2+(y-3)^2=(3\sqrt{2})^2$

the radius is $3\sqrt{2}$
center is (-2,3)

find distance between (8,4) and (-2,3)

$D=\sqrt{(8-(-2))^2+(4-3)^2}$
$D=\sqrt{(8+2)^2+(1)^2}$
$D=\sqrt{10^2+1}$
$D=\sqrt{100+1}$
$D=\sqrt{101}$

$r=3\sqrt{2}$ ≈4.2
$D=\sqrt{101}$ ≈10.04

do r<D

(8,4) is outside the circle

Find the value of x. If necessary, round to the nearest tenth.

Ghella [55]

Answer:

x = 10.3 in

Step-by-step explanation:

To find the value of a, use the area formula for a triangle. The formula is A = 1/2 *b*h. Here b = x and h= x. The formula becomes A = 1/2 *x². Substitute A = 53 and solve for x by using inverse operations.

A = 1/2x²

53 = 1/2x²

106 = x²

√106 = x

10.3 = x
