Answer: Yes

Step-by-step explanation:

x = 3

y = -7

10x + 20y ≥ -3

10 (3) + 20 (-7) ≥ -3

30 + (-140) ≥ -3

30 - 140 ≥ -3

-110 ≥ -3

(3, 7) is a solution

Answer:

y=3/4x+10

Step-by-step explanation:

lts take two points

(-4,7)

(0,10)

so slope is 3/4

so 3/4*-4+b= 7

-3+b=7

b=10

y= 3/4x+10

if my answer helps please mark as brainliest.

Answer:

y = 3/4 x + 10

Step-by-step explanation:

the b is 10 because y is 10 when x is 0

to find the x, plug in any variable from the chart into the equation y=mx+b

i used (-4, 7), so the equation would be 7=m(-4)+10

solve for x

-4m=7-10=-3

m=3/4

Answer:

y = 30

x = 150

Answer:

a) d = 3.6t

b) 10.8 miles

c) 1.2 hours

Step-by-step explanation:

For part a:

Slope of a line: y = mx + b

In this case, the equation would be: d = mt,

where m represents the speed Caden is walking at.

Note: b = 0 in this case because when Caden starts walking on the treadmill, he hasn't really covered any distance yet.

Therefore, plugging in a speed of 3.6 miles per hour, the equation is:

d = 3.6t

For part b:

This is a simple instance of plugging in 3 hours for our t value.

Therefore, d = 3.6 (3)

d = 10.8 miles

For part c:

In this case, we are given that d = 4.32 miles.

Therefore, 4.32 = 3.6t

Dividing both sides by 3.6, we get

t = 1.2 hours

Answer:

First and third options are equivalent, second and fourth options are not equivalent.

Step-by-step explanation:

Remember the relation:

[tex]a^n*a^m = a^{n + m}[/tex]

and:

[tex](a^n)^m = a^{n*m}[/tex]

We have the expression:

[tex]7^{1/5}*49^{7/5}[/tex]

We know that 49 = 7*7

Then we can write the above relation as:

[tex]7^{1/5}*49^{7/5} = 7^{1/5}*(7^2)^{7/5}[/tex]

We can use the second relationship from the above ones and write this as:

[tex]7^{1/5}*(7^2)^{7/5} = 7^{1/5}*7^{2*7/5} = 7^{1/5}*7^{14/5}[/tex]

Now we can use the first relationship to get:

[tex]7^{1/5}*7^{14/5} = 7^{1/5 + 14/5} = 7^{15/5} = 7^3 = 343[/tex]

Then:

The first option is equivalent.

The second option is not equivalent

The third option is equivalent.

The fourth option is not equivalent.

In algebra, the highest power of the variable is known as the degree of the expression. Note: If the degree of an algebraic expression is 1 then it is called linear expression. If the degree of an algebraic expression is 2 then it is called quadratic expression.

Answer:

It would take 2.5 cups of flour to make 1 loaf of bread.

Step-by-step explanation:

You would 7.5 divided by 3 to get how much it would take for 1 loaf of bread.

7.5/3 = 2.5

it would take 2.5 cups of flour to make 1 loaf of bread.

Answer:

5.5 km

Step-by-step explanation:

P.S - The exact question is -

As from the figure , we can see that

2 square = 1 km

Now,

Number of squares between P and Q = 4

Number of square between Q and R = 7

So,

Total number of squares = Number of squares between P and Q + Number of squares between Q and R

                                          = 4 + 7 = 11

⇒Total number of squares = 11

Now as

2 squares = 1 km

⇒ 1 square = [tex]\frac{1}{2} km[/tex]

⇒11 square = [tex]\frac{11}{2} km = 5.5 km[/tex]

∴ we get

total distance, x + y = 5.5 km

Answer:

$20

Step-by-step explanation:

To find the total bill, divide the tip amount by 0.15

3/0.15

= 20

So, his total bill was $20

Answer:

6 minutes

Step-by-step explanation:

Speed of net = 15mbps

Time taken = 4min.

Total size of application= 15*60*4= 3600mb

Now speed = 10mbps

Time taken = 3600/10

= 360 sec = 360/6 min

= 6 min

Answer:

Step-by-step explanation:

I think you mean 0.5 in:20 mi

2 in × (20 mi)/(0.5 in) = 80 mi

2 inches on the map corresponds to 80 miles.

8 miles is the real distance that corresponds to the 2 inch map measurement.

We can utilize the map's scale to get the actual distance that corresponds to the 2 inch map distance.

The scale is presented as 0:5 in:20 mi, which implies that each 5 inches on the map corresponds to 20 miles in actual travel distance.

Let's establish a ratio to determine the actual distance:

5/2 = 20/x

If we cross-multiply, we obtain:

5x = 2(20)

5x = 40

When we multiply both sides by 5, we get:

x = 40 / 5

x = 8

Therefore, 8 miles is the real distance that corresponds to the 2 inch map measurement.

Step-by-step explanation:

Answer:

D. xz=yz, angle z is shared, wz=wz

Answer:

Side-angle-side postulate

Step-by-step explanation:

First,  you know that angle XZW = YZW because they are both 90 degrees.

Next, you know that side WZ = side WZ because of the reflexive property (they are the same side)

Lastly, you know that YZ = XZ because Z is the midpoint meaning it divides the entire thing perfectly in half

You have two sides and the included angle, so it is SAS.
