The sum of the digits in a two-digit number is 16. The digit in the tens place is 2 more than the digit in the
ones place. The system of linear equations shown below represents this situation, where x is the digit in
the tens place and y is the digit in the ones place. Solve the system to find the two-digit number.
(x + y = 16
Ix-y=2
The two digit number is

Answer:

y = x+6

Step-by-step explanation:

You can see that (0,6) and (1,7) are points on the line, and the y-intercept of the line is 6.

Use the coordinates of these points to find the slope of the line.

slope = (7-6)/(1-0) = 1

y-intercept = 6

Slope-intercept equation for line of slope 1  that has y-intercept of 6:

y = x+6

Answer:

[tex]\frac{3}{2}[/tex] [tex]or[/tex] [tex]1\frac{1}{2}[/tex]

Step-by-step explanation:

We are given a graph and asked to find the slope.

So we can see two coordinate points, one on (0, 3) and (2, 0).

When trying to find slope, we use the method rise over run, which basically means y over x as a fraction, in which you then divide.

So count how many times it'll take for x to get to y, base it off the picture below

Since we see our numbers to be divided are 3 over 2, do the division and you get 1 1/2.

Would this be negative though? No, since the graph is in an increase, not a decrease.

Step-by-step explanation:

This is not the same exact question but it shows you the throw down.

A+B+C= 180

so if A=60 and B=70

The sin is= 8

so 60+70= 130

130+c=180

130-180= 50

C=50

Answer:

a=40 degree( vertically opposite angle)

a+b+90=180( area of triangle)

or, 40+ b+ 90=180

or,b=180-130

b=50 degree

c+65=180 (st.line)

or, c= 180-65

c= 115 degree

Answer:

the domain for both graphs is infinity

Step-by-step explanation:

both graphs are absolute value graphs, which means there is an infinite amount of possible x values in positive and negative directions.

edit: actually, if there are no arrows of the ends of the graphs, then what i just said is not true. a possible answer if that's the case may be both graphs have domains that include negatives

Answer:

Null, H0: μ ≥ 16

Alternative ; H1: μ < 16

reject H0

Step-by-step explanation:

Null, H0: μ ≥ 16

Alternative ; H1: μ < 16

To compute the test statistic :

We need the sample mean and sample standard deviation :

15.87, 16.02, 15.78, 15.83, 15.69, 15.81, 16.04, 15.81, 15.92, 16.10

Using calculator :

Sample mean, m = 15.887

Standard deviation = 0.13

Test statistic :

(m - μ) / s/sqrt(n)

(15.887 - 16) / 0.13/sqrt(10)

-0.113 / 0.0411096

= - 2.749

Tcritical at 95%

Tn-1, 0.025

T10,0.025 = 2.262

Since the test statistic value is less than the critical value, reject H0

Answer:

  (-1, -2)

Step-by-step explanation:

The difference between the coordinates of the image and the coordinates of the original is the same for both points.

  X - (0, 2) = (5, 2) -(6, 6)

  X = (5, 2) -(6, 6) +(0, 2) = (5-6+0, 2-6+2)

  X = (-1, -2)

The image of the point after translation is (-1, -2).

Find x

The relationship between x, 47 and [tex]17^{\circ}[/tex] is:

[tex]sin(17^{\circ}) = \frac{x}{47}[/tex]

i.e.

[tex]sin(\theta) = \frac{Opposite}{Hypotenuse}[/tex]

Solving further:

[tex]sin(17^{\circ}) = \frac{x}{47}[/tex]

Make x the subject

[tex]x = 47 * sin(17^{\circ})[/tex]

[tex]x = 47 * 0.2924[/tex]

[tex]x =13.7428[/tex]

[tex]x =13.7[/tex] --- approximated

Answer:

What is the Measure if what?

Step-by-step explanation:

GKW = 39°

PKG = 61°

PKW = 90°

PKF = 90°

FKM = 39°

PKM = 129°

WKF = 180°

WKM = 219°

Answer:

1.W&M=141 degerees

2.M&F=39 degerees

3.F&G=141 degerees

Step-by-step explanation:

1= if g&w were 39 degerees to search w&m

= 180-39=141degerees

w&m=141 degerees

2=the same with g&w

3= the same with w&m

Answer:

there are 3 1/6 pieces

Step-by-step explanation:

since 3 x 1/6=3/6.

another explanation:

(3/6)/(1/6)=(3/6) x (6/1) since you multiply by inverse when dividing fractions. Then, (3/6) x (6/1) = 18/6, which equals 3.

Answer:

See below

Step-by-step explanation:

The domain of [tex]f[/tex] is non-negative real numbers, and the domain of [tex]g[/tex] is real numbers.

[tex](f\circ g)(x) = 2\sqrt{2}|x|^5[/tex] (I skipped calculation details), so [tex](f\circ g)(9) = 2 \sqrt{2} \cdot 9^5[/tex].

Answer:

Isabella earned $48 from Nara. Isabella earned $16 from Hector. Isabella sells petunias for $6 per bunch (the number of petunias per bunch is unclear).

Step-by-step explanation:

Nala bought 12 roses which is greater than 10. So she received a $1 discount for each one. Nara spent 12*4=$48 dollars.

Hector bought 4 bunches of daisies meaning  that Hector spent 4*4=$16.

Petunias cost $6 per bucnh.

Step-by-step explanation:

1.5 is the radius so you plug it into [tex]\pi r^{2}[/tex] to get about 7.07 than do get the volume of a sphere you multipy by (4/3). I used my phone so you may want to use a ti84 so you can reuse the answers to get it more exact. It is a rounded answer with rounds at each step.

Answer:

y= -49.26 or -49 6/23

Step-by-step explanation:

First distribute the 23 to y and 57

23y+1311=178

then subtract 1311 from both sides

23y=-1133

Then divide 23 to both sides

y= -49.2608695652

rounded: -49.3

as a fraction: -49 6/23
