Answer:
d is correct
Step-by-step explanation:
the equation of the line which has a gradient of 3 and passes through the point (-1,3)
Answer:
Call the line (d): y = ax + b
(d) intersects the vertical axis at the point where the intersection is 3 ⇒x = 0, y = 3 Instead of (d) we have: b = 3
(d) intersects the horizontal axis at the point where the coordinate is -1 ⇒x = −1, y = 0 Instead of (d) we have: −a + b = 0
Replace into b = 3 into -a + b = 0 we have: −a + 3 = 0⇔a = 3
So the equation for the line is y = 3x + 3

Please help me answer this.
Answer:
B. Positive slope
Step-by-step explanation:
The line on the graph is positive, as it grows from left to right.
Answer:
Positive Slope
Step-by-step explanation:
The line goes up, which means that it's positive. To be exact the line equation is y = 3x + 1. The slope (3) is positive, which proves that its a positive slope, not negative.

9. Fred bought 24 new baseball cards for $50. There were two types of cards. One type cost $1 per card, and the other cost $3per card. Define the variables, and write a system of equations to find the number of each type of card he bought. Then solve the system using the best method for the situation.
Answer:1$ cards = 11 cards 3$ cards= 13
Step-by-step explanation:the first equation is -x-y=-24 and the second is x+3y=50. Solving them as a system will get 2y=26 to y=13 then plug in 13 to the y for -x-y=-24 to get 11. Mr jacobs is hard I know lol. Use elimination by subtraction and keep the first equation as x+y=24 and then flip to negative

A ladder rests 22 feet up the side of a building. If the base of the ladder is 20 feet away from the building, how tall is the ladder to the nearest hundredth?
Answer:
Length of ladder =L =15
Distance from wall = D =9
Height on wall = H =??
Pythagoras equation L*L = D*D + H*H
15×15= (9×9) + H×H
225-81 = 144 =HxH
H= 12 feet.

Which set of numbers describe the side length of a right triangle
Answer: 3,4,5
Step-by-step explanation:
5² = 3² + 4²
25 = 9 + 16
25 = 25
The set of numbers 3, 4, and 5 describe the side length of a right triangle.
Option C is the correct answer.
What is the Pythagorean theorem?Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We have,
Set of numbers:
1, 2, 3
2, 3, 4
3, 4, 5
4, 5, 6
We need to find the set of numbers that describe the side length of a right triangle.
We will apply the Pythagorean theorem to all the sets of numbers.
Using 1,2,3.
1² = 2² + 3²
1 = 4 + 9
1 = 13
2² = 1² + 3²
4 = 1 + 9
4 = 10
3² = 1² + 2²
9 = 1 + 4
9 = 5
This is not true.
Similarly,
Set of numbers: 2,3,4 and 4,5,6 are not true.
Using 3, 4, 5
5² = 3² + 4²
25 = 9 + 16
25 = 25
This is true.
Thus,
The set of numbers 3, 4, and 5 describe the side length of a right triangle.
Option C is the correct answer.

Find the slope of the line that passes through (10, 92) and (97, -3).
Answer:
-95/87
Step-by-step explanation:
Formula to find slope: (y2-y1) / (x2-x1)
In this problem y2 is -3 and y1 is 92. x2 is 97 and x1 is 10.
We substitute these numbers into the equation.
(-3-92) / (97-10)
Then we simplify this by subtracting.
-95/87 is our final answer.

What single decimal multiplier would you use to decrease by 6% followed by a 7% increase?
Answer:
the single decimal multiplier is 1.0058
Step-by-step explanation:
Let us have 100
Decreasing by 6% will be
100 - 0.06(100)
= 94
Increasing by 7%
= 94 + 0.07(94)
= 100.58
So
to get the single decimal multiplier,
we have 100.58/100 = 1.0058
